Abstract:
A system for assessing the diagnostic reasoning ability of learners engaged in a field of study employs a coded situation test and utilizes a computerized process for grading examinations taken by the learners and for rating their capacity for diagnostic reasoning. The computerized diagnostic reasoning evaluation instrument embodies storage in a test file of the situation test description which describes, illustratively in narrative form, a plurality of problems associated with the situation test employing a plurality of phrases. Each phrase has associated therewith a respective phrase identification symbol which is used by the examinee to record answers to the examination. In a nursing embodiment of the invention, each learner selects from a listing of possible problems. Those problems which are considered by the learner to be significant and present in the situation test are then identified by storing their respectively associated code symbol. In practice, the answers by the examinee may be entered directly into a computer by the examinee, or may be recorded by the examinee on paper and later entered into the grading computer by someone else. Subsequently, the learner is asked to identify which of the selected problems are significant using supporting data, and create from coded objectives, criteria, interventions, and rationale listings an intervention plan which is proposed by the learner to resolve the major problems. Grading is achieved by reference to a computerized answer key generated by an expert, such as a teacher, and stored in a computer memory as an answer key.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates generally to evaluation systems, and more particularly, to a system which employs a computer for assessing the diagnostic reasoning skills of an individual, particularly of a learner/trainee in any field of study using situations, including the case method of study, or where evaluation of learner performance is achieved using situation tests. 
     In a variety of disciplines, the situation test method of learner evaluation has been accepted as the preferred approach. The case study methodology has associated therewith the significant advantages of providing a vehicle for generating discussion among learners and dialogue with a teacher. Additionally, the study of a case affords the learner considerable opportunity to apply his or her knowledge and reasoning skills in a predetermined situation test. 
     One of the major problems in the case study method of teaching is in grading a multiplicity of learners objectively and consistently. For example, in institutional teaching situations where hundreds of learners are taking the same test, the percentage of agreement among the various experts who grade the tests is low. This percentage remains low even when the experts are provided with grading criteria. 
     One field which has traditionally employed the case study method is health care education. It is extremely important that persons involved in nursing and other health-related disciplines have well-developed problem-solving and critical thinking capabilities. An individual practicing in these fields is required to determine the problems of a patient from a case history, or narrative, which includes factual information derived objectively and subjectively. The individual must then select from the problems those which are of primary importance to warrant an intervention. Of course, once there is a determined need for intervention, an intervention plan must be developed. It is significant in the education process of such individuals to ascertain, preferably by quantification, the extent to which they have succeeded in developing their critical thinking and problem-solving capabilities. 
     It is, therefore, an object of this invention to provide a system for evaluating reasoning and analysis capability of individuals. 
     It is another object of this invention to provide an evaluation system which assists a teacher/trainer in identifying aptitudes and deficiencies in learners relating to identifying problems in given situations and selecting data in support of these problems. 
     It is also an object of this invention to provide an evaluation system which assists a teacher in identifying aptitudes and deficiencies in learners relating to planning of corrective intervention after identifying problems in given situations. 
     It is a further object of this invention to provide a computerized evaluation system which assists a teacher in identifying aptitudes and deficiencies in learners relating to identifying problems and planning corrective intervention in given situations. 
     It is additionally an object of this invention to provide a computerized system for assisting a teacher in assessing the ability of a learner to identify major problems in a plurality of potential problems. 
     It is yet a further object of this invention to provide a computerized system for assessing the diagnostic reasoning skills of learners in health-related fields of study. 
     It is also another object of this invention to provide a computerized system for assessing diagnostic reasoning skills of learners in fields of study which use situation tests to assist in evaluating learners. 
     It is yet an additional object of this invention to provide a computerized system for assisting a teacher of a field of study which employs the situation test method in assessing the diagnostic reasoning skills of a large number of learners. 
     It is still another object of this invention to provide a computerized system for evaluating and assessing the problem identification skills of learners. 
     It is a yet further object of this invention to provide an objective, criterion-based, computerized testing and evaluation system. 
     It is also a further object of this invention to provide a testing and evaluation system which can provide substantially immediate feedback of learner performance to a teacher and a learner. 
     It is additionally another object of this invention to provide a testing and evaluation system for use in conjunction with a computer, whereby the examinations of a plurality of learners are objectively evaluated in problem identification and intervention planning. 
     A still further object of this invention is to provide a testing and evaluation system for use in conjunction with a computer, whereby the diagnostic reasoning capability of a learner is evaluated substantially irrespective of the extent to which the learner completed the examination. 
     An additional object of this invention is to provide a testing and evaluation system for use in conjunction with a computer, whereby evaluation of the diagnostic reasoning capability of a learner is evaluated by monitoring the binary states of at least two software flags. 
     Yet another object of this invention is to provide a testing and evaluation system for use in conjunction with a computer, whereby an overall performance score of a learner is increased by extra effort on the part of the learner in completing an examination. 
     Another object of this invention is to provide a testing and evaluation system for use in conjunction with a computer, whereby correctness of rationale in support of an action is considered in the grading of a learner. 
     SUMMARY OF THE INVENTION 
     The foregoing and other objects are achieved by this invention which provides a method of operating a computing machine to assess the reasoning ability of an individual to be evaluated. In accordance with the invention, a situation test description which describes a plurality of characteristics associated with a situation test is stored in a test file. At least one question pertaining to the situation test, as set forth in the situation test description, to be answered by the individual is stored in a question file. In one embodiment of the invention, the question is in the form of a listing of choices whereby the individual to be evaluated selects one or more predetermined problems he or she believes is related to the situation test. A problem identification file sees and stores a problem identification response by the individual to be evaluated. The information received by the problem identification file is in the form of a code number corresponding to at least a selected one of the possible choices. 
     In a preferred embodiment of the invention, the phrase identification symbols associated with the plurality of phrases which form the situation test description, are stored in an answer file by the learner being evaluated to identify the specific ones of the phrases which support the answers selected by the learner. Thus, the learner forms a data relationship between the data provided in the narrative of the situation test, and the data which forms the bases of the questions to be answered, or problems to be solved, by the learner during the examination. The stored answers, which may include identification numbers or symbols associated with selected ones of listed possible problems, the components of an intervention plan to be proposed by the learner, and the supporting phrases of the situation test description are compared to predetermined answers stored in an answer key, which will be discussed hereinbelow, during grading. 
     Further in accordance with the invention, the intervention plan proposed by the individual to resolve a major one of the problems identified in the problem data relationship is stored in an intervention plan selection file. As indicated, in certain embodiments, the intervention plan selection file may be included in the answer file. The problem identification file includes specific data elements from the situation test description. The data elements are in the form of an identification file which may be part of the intervention plan file. It is to be understood that the term &#34;files&#34; correspond to any memorialization arrangement, such as computer memory, and need not have associated therewith any nomenclature. 
     In one embodiment of the invention, the intervention plan stored in the intervention plan selection file consists of a plurality of coded selection options selected by the individual to be evaluated. The plan may included coded listings of objectives, criteria, interventions, and reasons. Thus, within each such component of the intervention plan, there are listings of choices, each choice having an associated code number. In operation, the individual to be evaluated is requested to select one objective and at least one criteria for each problem in the problem identification file which has been identified as being major. The individual to be evaluated therefore will select from a plurality of each of objectives, criteria, interventions, and reasons. However, not every intervention plan need incorporate all such components during testing. Moreover, the identification of the problems, as well as the intervention plan, can be edited by the learner being evaluated prior to submission of the examination for grading. 
     In a computerized embodiment, an answer key is stored on a memory disk by a teacher or administrator of the examination. In a practical embodiment of the invention, the software can be accommodated on one disk, and includes a file portion for making separate disks for administration of the examination. The individual being evaluated can enter the answers to the examination at a computer or an answer sheet which then is entered into a computer. 
     The system permits a teacher to make disks containing the examination for distribution to individuals being evaluated, or the administrators of the examination. As will be described herein, the learner test disk will also contain at least a portion of a known operating system, such as a disk operating system, to permit the learner disk to be self-loading. 
     As previously noted, in a preferred embodiment of the invention, the software system contains an editor portion which permits the teacher to create an answer key for a given situation test. The answer key can be edited by the teacher at any time. There is further provided a disk-making portion which is used to place the examination on the separate learner disks. Finally, a correction portion of the software package is employed to grade the responses to the situation test. In a preferred embodiment, the grading process generates a print-out which describes the pattern of reasoning of the tested individual which yield three numerical scores: problem identification score, intervention plan score, and total score. The resulting plurality of scores can be subjected to group analysis. Thus, groups of learners can be compared, thereby permitting diagnosis of reasoning deficiencies which apply to the group of learners as a whole, so as to enable development of corrective training program. 
     A measure of security is achieved by the production of an individual disk(s) for each of the learners being evaluated. In this manner, a learner cannot obtain the test results of any other learner. Additionally, the learners can be identified by learner numbers, which permit posting of grades in a conventional manner without identifying the particular individuals. 
     In the practice of the invention, the system, from the standpoint of the learner, is initialized, illustratively by booting in a conventional manner, and identification information is requested. After the entry of the identification information, the answer files are opened and instructions are displayed on the screen to commence the examination. When the examination is completed, the information is stored in the answer files on the disk, and the answer files are closed. 
     During the examination, the test begins with the problem identification section. After reading the situation test description, the individual being evaluated selects from a listing of possible problems, those codes which are believed associated with problems raised by the situation test description, which in a specific illustrative embodiment may be a medical situation in narrative form. Prior to proceeding with the generation of an intervention plan, the learner being evaluated is afforded an opportunity to edit the answers to the problem identification section, prior to their being entered on the computer disk. 
     Upon completion of the problem identification section, the learner being evaluated commences the intervention plan section. In this section, the learner is requested to select a predetermined number of the problems identified in the previous section on the basis of a determination by the learner that their significance as problems is sufficient to warrant intervention. As previously indicated, the intervention plan is created by selecting appropriate choices from several options within listings of problems, objectives, criteria, interventions, and rationale, for each major problem, or each problem of primary importance. As also previously indicated, the listings are coded by number, each listing including correct and incorrect choices. 
     An &#34;objective&#34; is defined as a measurable behavior expected to guide intervention. &#34;Criteria&#34; is an outcome which describes achievement of objectives. An &#34;intervention plan&#34; is defined as a plan of action for solving a given situation. In a nursing embodiment of the invention, multiple interventions, illustratively five interventions, can be listed for each major problem along with rationale. &#34;Rationale&#34; is a reason cited by the learner for specific action. 
     In this embodiment, the intervention plan for each major problem is rated. For example, each correct action and an associated correct reason receive a score of one point. Thus, only one-half point is given if action is correct, but the rational is incorrect. Thus, in this embodiment, the classifications of intervention plan can include &#34;correct intervention,&#34; &#34;intervention plan with some validity,&#34; and &#34;intervention plan without validity.&#34; In this particular embodiment, if the intervention plan for a selected major problem is correct, it is labeled as &#34;correct intervention.&#34; If three of five actions are correct, it is labeled as &#34;intervention with some validity.&#34; A rating of &#34;intervention without validity&#34;  occurs when four of five actions entered are incorrect. An intervention rating is calculated for each of the major problems. 
     In a specific illustrative embodiment of the invention which is suitable for use in health care education, particularly nursing education, an illustrative respondent version of an examination directed to a case study would appear as follows:

(21) When this happened, the nursing home staff reported that she either cried or attempted to hide. 
     (22) Miss Giordano was never married, lived alone and was a grammar school teacher until her retirement at age 65. (23) Her parents came to America from Italy and her religion is Roman Catholic. (24) Her sister, who is her only living relative, says that she was a hard-working fastidious person all of her life. (25) She was devoted to her job and (26) kept to herself for the most part after she retired. (27) Her health was always good, and she was never hospitalized until now. (28) Her medical diagnosis in the nursing home was Dementia, and her only (29) medication was Restoril 15 mg po HS. 
     (30) In the hospital, Miss Giordano has been quiet and cooperative with the nursing staff. (31) She is disoriented to time and place, (32) but responds to her own name and can identify herself. (33) She seemed to recognize her sister and brother-on-law when they visited last night, (34) however, she called them by the wrong names. (35) She is on complete bed rest (36) but in no apparent discomfort except during position change. (37) The admitting physician prescribed Darvocet N-100, which she received at 2 AM.

     The answer key to a situation test is created using a teacher disk containing software which, in this embodiment, is called &#34;EDITOR.COM.&#34; This software can also be used to edit or correct answers to a previously generated situation test. Additionally, help screens may be included for the purpose of facilitating usage of the software. The teacher disk may further be provided with another section of software &#34;CORRECT.COM&#34; which is used to grade the answers of the learner. In one embodiment, the learner disk, which contains the learner&#39;s answers, is inserted into a drive of a microcomputer, and the teacher disk is inserted into a second drive. The learners&#39; answers are then compared against those in the answer key, and the resulting score can be written into an individual file maintained on magnetic media. The CORRECT.COM program first obtains the learner&#39;s answers, grades the problem identification section, and then grades the intervention plan. The learner&#39;s answers and scores are then printed for review. 
     Grading of the problem identification section and the intervention plan section is, in this embodiment of the invention, performed separately. However, the results of such grading may be presented in a unified, or consolidated, report, not only of the various sections for each examinee, but also for the various examinees. In this manner, the members in a group of examinees can be compared to one another, and as a group, to assist in the development of norms for the group, and of corrective curricula. 
     It is a particularly advantageous feature of the invention that the situation test and additionally the accompanying problem choices may be entered into a computer using any commercially available word processing software package. Alternatively, these may be provided in a test booklet which accompanies the software. This feature facilitates administration of the examination selectably independent of a computer, or with a computer. 
     An essential aspect of the invention is the ability to yield both, numerical and rating scores for both, assessment and plan sections. The plan section of the inventive process includes the multiple combinations of five components, including hypotheses, objectives, criteria, interventions, and rationale. There is no restriction on the number of problem choices or hypotheses. 
     As indicated in the examination, the examinee is directed to select from the problem listings the most important problems. Next he or she is directed to select the objective, criteria, intervention, and rationale for each major problem identified using the listings provided. Only one objective is allowed for each major problem. Each of the listings provided within the situation test include distractors. One to three criteria may be used for a major problem, in this specific embodiment, and one to five interventions and rationale for interventions may be used for each major problem. Interventions and rationale are scored separately, but the system of the present invention also looks for a match between a specific intervention and specific reason. Some known grading systems ask the examinee to provide interventions, but generally do not ask for rationale, or grade its relationship to specific interventions. 
     The process of the present invention also includes in certain aspects thereof creation of a situation test, which is independent of the grading process. The focus of the software process is to grade the responses of an examinee to a given situation, and to compare the responses to an answer key. In some embodiments, this results in the production of an individualized printout containing indications of the validity of the responses by the individual examinee, rather than merely a global response which states only the percentage of correct responses by the examinee. 
     In accordance with another significant aspect of the invention, and as will be described hereinbelow with respect to FIGS. 2-8, not all of the six components noted hereinabove need be used in every examination environment. In those environments where the software pertaining to the entire, or master, system is employed, but not all components are required, the portion of the printout pertaining to the unused components may appear as all zeroes. It is to be understood, however, that the present invention is not limited to the specific combinations of components indicated hereinbelow. 
     In the creation of an examination in accordance with the master diagnostic reasoning evaluation instrument of the invention, the following essential components of a situation test are required: 
     1. Narrative description of situation with numbered phrases or elements. 
     2. Problem and hypothesis listings, preferably with distractors. 
     3. Objective listing with distractors. 
     4. Criteria listing with distractors. 
     5. Intervention listing with distractors. 
     6. Rationale listing with distractors. 
     7. Answer key prepared by trainer/teacher or panel of experts including correct responses as follows: 
     a. Problem choices with substantiating data phrases with coded numbers for each such problem choice. For example, consider the following: 
     Problem: Malnutrition (2) 
     Substantiating data: 
     1: Weight loss Δ=(2) 
     2: Protruding abdomen Δ=(4) 
     3: Low Hemoglobin Δ=(12) 
     4: Fatigue Δ=(30) 
     b. Hypotheses or major problem choices with intervention plan for each major problem, with coded numbers for each.

     DETAILED DESCRIPTION 
     FIG. 1 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to assess a situation and propose a valid intervention plan. As shown in this figure, there are six major components of the general system, the components being entitled &#34;assessment,&#34; &#34;hypothesis,&#34; &#34;objectives,&#34; &#34;criteria,&#34; &#34;interventions,&#34; and &#34;rationale.&#34; As will be discussed hereinbelow with respect to the other drawing figures, these six elements can be combined in different manners in accordance with the reasoning patterns of respective disciplines of fields of study. In FIG. 1, however, the master design is represented for a system which evaluates the diagnostic reasoning required in a complex field, illustratively health care nursing. 
     In the master design shown in FIG. 1, assessment and plan are the two central ingredients for diagnostic reasoning. Assessment is based on the identification of problems for a given narrative description. The written situation test, as indicated previously, contains coded phrases which are both relevant and irrelevant. The learner, or examinee, being evaluated is first provided with the narrative and then is asked to select by number from a listing of problems which may or may not be inherent in the situation, and which the professional should address. In addition, the examinee is expected in this embodiment to select illustratively between one and four data phrases by number from the narrative description which support each problem choice. 
     The master flow diagram of the diagnostic reasoning instrument of FIG. 1 illustrates that the data choices are classified as RELEVANT or IRRELEVANT. The ability of an examinee to make an assessment is scored numerically and rated as assessment with validity (AV), assessment with some validity (AWSV), and assessment without validity (AWV). A numerical score for this section is based on a predetermined weighting for each problem identified by the examinee. The rating for this section is based on the total number of problems identified correctly and incorrectly. 
     The PLAN section of the diagnostic reasoning instrument of FIG. 1, which is the most comprehensive form, consists of five components: 
     1. HYPOTHESES are responses by the examinee to the examination question, &#34;Select from your problem choices the most important problems.&#34; The learner is expected to delimit further the problem choices using the same problem listing provided in the situation test and used for assessment. A rating classification for these choices is provided in a computerized printout (not shown) to the learner, but not a separate numerical score. The ratings for HYPOTHESES are classified as appropriate (AH), mixed (MH), inappropriate (IH), and no hypothesis (NH). These ratings are determined by number and are dependent upon the accuracy of the major problem choices. 
     2. OBJECTIVES are selected by the learner for each major problem from a listing provided within the situation test. The program of the present invention, as will be described hereinbelow, grades these response as correct or incorrect, but no rating is provided. These response are stored for grading purposes. 
     3. CRITERIA describe achievement of an OBJECTIVE and are also provided in a listing. The learner is expected to select, in this specific illustrative embodiment, between one and three CRITERIA for each major problem. The selections are graded by the program of the present invention as correct or incorrect. 
     4. INTERVENTIONS which are determined by the examinee as being required to be taken by the professional to solve the client problems are provided within the situation test. In this specific embodiment, the program restricts these choices to a maximum of 5 for each major problem, or within a range of 1 to 5 interventions for each major problem choice. Each INTERVENTION choice is graded as either correct or incorrect, and the program determines whether it matches a predetermined RATIONALE. An intervention rating is calculated for each major problem based upon the degree of match with the answer key. Intervention classifications are: intervention with most validity (IWMV), intervention with some validity (IWSV), and intervention without validity (IWV). A one-half point is given for each correct intervention (CI). 
     5. RATIONALE are selected from a listing by the learner for each intervention selected. Each RATIONALE is rated as either correct or incorrect by the program, and a rationale rating is derived on the basis of RATIONALE choices for each major problem. The rationale ratings are: relevant rationale (RR), mixed rationale (MR), incomplete rationale (IR), and rationale without validity (NR). 
     As is evident from the foregoing, the master, or general, diagnostic reasoning instrument of the present invention, as shown in FIG. 1, includes two sections, assessment and plan, with a total of six components. After completion of the examination by the examinee, the process of the present invention grades all of the components, resulting in three numerical scores and four ratings. The ASSESSMENT numerical score is based on the problem choices with supporting data phrase. The PLAN numerical score is based on choices for HYPOTHESES, OBJECTIONS, CRITERIA, INTERVENTIONS, and RATIONALE. A total score for a given situation test is the combined numerical score for both the ASSESSMENT and PLAN sections. The four ratings are for ASSESSMENT, HYPOTHESIS, INTERVENTION, and RATIONALE components. 
     FIGS. 2-8, described hereinbelow, pertain to various combinations of the elements noted hereinabove in the master diagnostic reasoning instrument, the diagnostic reasoning instruments formed of such combinations being adaptable to specific fields or disciplines: 
     FIG. 2 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to work up a diagnosis. The model of the diagnostic reasoning instrument represented herein includes the two components of ASSESSMENT and HYPOTHESIS. Thus, this instrument is particularly suited for use in fields which focus on diagnosis. The primary emphasis of the field of medicine is on the identification of a diagnosis based on taxonomy. An integral part of a diagnostic work-up includes the data collection and the sorting of data. The collecting of the correct data, not just a large amount of data, must be performed before a correct diagnosis can be achieved. Generally, a physician makes a list of possible hypotheses at the conclusion of a physical examination and after obtaining a medical history. The advantage of the present inventive program over this process is that it can quickly test a learner and/or practitioner&#39;s ability to perform the assessment and diagnosis process properly. The diagnostic reasoning instrument of FIG. 2 should be used for fields which focus on written diagnosis formation based on sound or standardized data collection methods. 
     FIG. 3 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner, illustratively in the field of equipment repair, to assess a situation and effect repair. This diagnostic reasoning instrument focuses on ASSESSMENT and PLAN components. Technicians and repair service personnel are expected to assess a situation and then repair the equipment problem. The advantage of the present program is that it will accept any situation that a trainer designs and it is not limited to a specific field of endeavor. Thus, this system can be used to evaluate the skills of, for example, computer technicians, auto mechanics, or engineering technicians. In addition, this system can be used to determine the ability of an administrative assistant to assess a situation and intervene. Such situations can relate to equipment or clients. 
     FIG. 4 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner, illustratively in a sales field, to assess a consumer, generate an objective as to what to sell within a given situation, and make a sale. A critical component of making a sale is to have a plan. The diagnostic reasoning instrument of this figure utilizes OBJECTIVES, INTERVENTIONS, and CRITERIA as the three components of a PLAN, or sales presentation. In various sales industries, it is understood that terminology may differ from that presented herein, but the components remain the same. 
     FIG. 5 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to produce an intervention pursuant to a PLAN based on CRITERIA which need not be verbalized. For example, an architect focuses on a plan for a given situation and may write or state an OBJECTIVE, and make a drawing (intervention). The criteria may be, for example, whether the building will stand, but this criteria need not be stated. The primary focus of this field is the INTERVENTION design (plan). 
     FIG. 6 is a block and line representation of diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to make a HYPOTHESIS and specify INTERVENTIONS. Thus, the PLAN is the INTERVENTIONS, and therefore the diagnostic reasoning instrument of this figure is helpful in evaluating the creativity of a learner. Data collection is not specified as an integral part of this process. A learner may have an idea about the environment and a plan to carry it out, but the situation may or may not be confined to a natural environment or one known to any extent by the examinee. For example, the environment may be artificial, such as voice synthesis. 
     FIG. 7 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to assess a given situation using verbalization of data, and formulate a PLAN using valid CRITERIA. This diagnostic reasoning instrument is useful in assessing how humans should approach daily situations. First, a situation must be assessed completely by collecting data. Then a PLAN is created, using HYPOTHESIS and CRITERIA. In fields where the emphasis is on a verbalization of assessment stage and data sorting, prior to determining the problem, this system is appropriate or applicable. In this system, intervention is of secondary importance or not a consideration at all, whereas thinking is primary. Examples of fields in which this system could be used include logic, philosophy, and aesthetics. 
     FIG. 8 is a block and line representation of a diagnostic reasoning instrument which is useful in providing an evaluation of the ability of a learner to assess a given situation, and articulate HYPOTHESES and RATIONALE. This system is particularly adaptable to the physical sciences which focus on premises (ASSESSMENT), conclusions (HYPOTHESES), and criteria (RATIONALE). This system emphasizes the major goal of the physical sciences which is to make discoveries. 
     FIG. 9 is a block diagram which is useful in describing generally the process of taking an examination in accordance with the invention. First, the program variables are initialized, at step 10, illustratively by booting the system which may be installed on a computer disk containing at least a portion of a disk operating system. Such initialization results in production of a screen (not shown) at step 11 which could be used to identify the school or institution, or any other similar information. The learner then enters his or her unique information at step 12 which results in the opening of the files at step 13. Subsequently, at step 14, the examination is taken and the learners&#39; answers are stored at step 15. Upon completion of the examination, the answer files are closed, at step 16, and the process is stopped at step 17. 
     FIG. 10 is a logic flow chart which illustrates the taking of the examination. Initially, at step 20, a determination is made whether any problems have yet been identified. Prior to commencing the examination, no problems have been identified, and therefore the system proceeds to step 21 where the code numbers associated with selected ones of the problem choices are entered. The program then proceeds to a command step 22 where a decision is made by the learner whether to edit the program identification information, or proceed to the intervention plan section. If edit is desired, the process returns to step 20, and, since program identification information has been stored, editing information is generated at step 23. Upon completion of the editing, the process returns to command step 22, and a similar process is repeated for the intervention plan. 
     In the intervention plan portion of the examination, a determination is made at step 24 whether the intervention plan answers have been entered, and if not, the process proceeds to step 25 where the learner enters the intervention plan. Again, if the learner desires to edit the intervention plan, such editing can be achieved at step 26. After editing, a decision is made at command step 27 whether or not to quit, as shown at step 28. 
     FIG. 11 is a logic diagram of the process present on the teacher disk for creating and editing answer keys. After initialization of the system and generation of a logo screen, the process proceeds to generate a menu, as illustrated at process step 30. If it is determined at process step 31 that editing is not desired, the process proceeds to request at step 32 whether help is required. If not, the new answers are created at step 33 and are entered at step 34. As shown, first the problem identification answers, and then the intervention plan answers are entered at step 35. This data is subsequently stored. However, if it is desired to edit the answer key, the appropriate key is selected at step 36. 
     FIG. 12 is a block diagram of a process for grading the answers of the learners. After initialization of the grade variables at step 42, the learner disk is inserted in drive A, in this embodiment, of a microcomputer system at step 43. In this specific embodiment, a menu is generated at step 44 which allows the teacher to grade individual learners, grade all of the learners at once, or obtain a list of learners who completed the situation test. Each learner&#39;s score is stored on the disk and can be printed. 
     FIG. 13 is a block diagram of an overview of the examination correction process. Learner information is obtained at step 51 and the problem identification and intervention plan sections are graded at steps 52 and 53, respectively. The learners&#39; answers and the resulting score are printed at steps 54 and 55. Finally, the learners score is written into a respective file at step 56. 
     FIG. 14 is a logic diagram of the examination grading process. Software flags I and J are initialized at step 60. In this embodiment, software flag I is set to &#34;true&#34; and software flag J is set to &#34;false.&#34; These flags allow the program to establish the conditions under which the learners&#39; answers to the problems are determined to be correct, partially correct, or incorrect. This process analyzes all of the responses for all of the problems, and provides a rating of the learner&#39;s overall judgment. The validity of the learner&#39;s judgment is measured irrespective of the number of problems which have been completed. However, in this embodiment of the invention, as will be discussed below, there is additionally provided a score which reflects the number of problems completed. In other words, credit is given for extra effort in completing additional problems during the examination. 
     In this embodiment, software flag I assumes a true state if all of the problems are correct. Software flag J assumes a true state if at least one problem is correct. Thus, the following conditions operate in the system: 
     
         ______________________________________SoftwareFlagsI     J______________________________________T     T      Assessed with validity, all problems correctT     F      Cannot existF     T      Some right and some wrong, assessed with some        validityF     F      All are wrong, assessed with no validity______________________________________ 
    
     This rating system can accurately evaluate the performance of a learner who might only answer one or two problems correctly. In addition to the software flags, a scoring system is also present to recognize extra effort by an individual who might work on many more problems in the same context with the same degree of accuracy. Both learners would achieve the same rating, but the learner who completed more problems would get a higher score. 
     After the initialization, the learners&#39; answers are read by the computer at step 61. The answers to the problem are compared for correctness at step 62, and if the answer is not correct, the I flag is set to false at step 63. However, if the problem was answered correctly, the data phrases are then examined at step 64. The number of correct data phrases found for each correct problem is divided by the total number of correct data phrases for that problem, and the resulting fraction is added to the score. 
     At step 66, a determination is made whether the problem was a major one. If so, at step 67, the problem score is added to the major problem total; otherwise it is added to the minor problem total in step 69. Then software flag J is set to true at step 68. 
     This sequence continues until all of the problems have been graded. At that time, the major problem score is multiplied by a predetermined number, illustratively 3, so as to provide more credit for recognizing the most important problems. Then the major and minor problem scores are divided by the total number of correct problems in their respective categories and both scores are combined. This results in a score of the overall assessment ability of the learner and the results are displayed or printed. 
     FIG. 15 is a logic diagram of a system for grading the intervention plan of a learner. After reading the learner&#39;s answer at step 70, a determination is made as to whether the problem is a major one. If the problem is major, one point is awarded for a correct objective in step 71. Then, the criteria is examined for correctness at step 74. The number of correct criteria found is divided by the number of correct criteria possible. The resulting fraction is added to the score. The interventions are then checked at step 75, and if the associated rationales are correct one point is added. However, if the rational is not correct, only one-half point is awarded. When all of the interventions for each problem have been evaluated, the score is divided by the total number of interventions for that problem. A rating is produced, illustratively as an output, for each problem. 
     If the problem is not major, then the system will search for more problems at step 73 until all problems are evaluated. When no further problems are found, the score is divided by the total number of problems and an output of overall scores and ratings is produced.
