## Title
Computer-implemented method of administering and scoring integrated reasoning question formats

## Abstract

Automated methods and systems are provided for presenting and scoring items which are presented in different question formats that include graphics interpretation, two-part analysis, table analysis, and multi-source reasoning. There are a plurality of response opportunities for each item, and each response opportunity is independent of each other. In operation, an item is presented in the respective question format on a processor-controlled user interface display screen. A response engine receives the response for each response opportunity. A scoring engine in communication with the response engine receives the plurality of responses and scores the plurality of responses by determining whether the response selected for each response opportunity is correct, and assigning credit for the item only if each of the responses for each of the response opportunities is correct, and assigning no credit for the item if at least one of the responses for each of the response opportunities is incorrect.

BACKGROUND OF THE INVENTION
A standardized test is a test that is administered and scored in a consistent, or “standard,” manner. As discussed in U.S. Pat. No. 6,234,806 (Trenholm et al.), which is incorporated by reference herein, standardized tests are administered to examinees (also, referred to herein as “test-takers, respondents, or users) for educational testing and evaluating particular skills. Academic skills tests include SATs, LSATs and GMATs.
The educational needs of modern society continue to evolve, and thus the desired academic skills that employers require likewise change. Academic skill tests thus must continue to evolve to properly gauge an examinee's abilities with respect to new skills. To meet this need, extensive research is conducted to identify the new skills that need to be tested for, and to create standardized test questions which can accurately measure the examinees' proficiency with respect to the new skills. Professionals, such as psychometricians who work in the educational measurement field, translate these identified skills into new test question formats and actual test questions. There are many feedback loops in the test development process. For example, even after suitable test question formats are identified and actual test questions are generated, it is still necessary to conduct extensive field tests over large populations of examinees to evaluate whether test responses are accurately measuring the examinees' proficiency with respect to the identified skills. Psychometricians use a plurality of well-known metrics to measure whether test responses from a pool of examinees meet this standard. Some of the metrics include item analysis, response latency analysis, form analysis, equating analysis and differential item functioning (DIF) analysis.
One important aspect in developing test formats is the scoring process. There are many ways to score a test. The manner in which test responses are presented and scored can greatly influence whether the test accurately measures the skills of the examinee that the test-giver wishes to gauge. Some scoring factors include whether full or partial credit is used and the score scale. For example, if a test provides multiple response opportunities for an item, the same exact test might be an inaccurate gauge of a skill to be measured if the scoring factors are not properly selected. Again, extensive analysis by psychometricians of field test results must be performed to confirm that a proposed scoring process should be adopted.
Furthermore, the field tests should be performed on a general population of examinees who are taking standardized tests in the ordinary course of their educational advancement, such as when applying to higher education programs. Performing tests in laboratory settings does not provide a sufficient environment to ensure that the test results will accurately reflect examinees' performance on a real-world version of the test.
SUMMARY OF THE INVENTION
Preferred embodiments of the present invention relate to automated methods and systems for presenting and scoring items which are presented in different question formats that include (i) graphics interpretation, (ii) two-part analysis, (iii) table analysis, and (iv) multi-source reasoning. There are a plurality of response opportunities for each item, and each response opportunity is independent of each other. The methods and systems operate as follows for each of the different question formats:
1. An item is presented in the respective question format on a processor-controlled user interface display screen.
2. A response engine receives the response for each response opportunity that is presented on the user interface display screen.
3. A scoring engine in communication with the response engine receives the plurality of responses and scores the plurality of responses by determining whether the response selected for each response opportunity is correct, and assigning credit for the item only if each of the responses for each of the response opportunities is correct, and assigning no credit for the item if at least one of the responses for each of the response opportunities is incorrect.
As noted above, each response opportunity is independent of each other. “Independent of each other” means that the test-taker can respond to each of the response opportunities without needing to know the responses (or the correct response) to any of the other response opportunities. Stated another way, the test-taker won't have to answer one question (response opportunity) correctly to be able to answer another (response opportunity).

DETAILED DESCRIPTION OF THE INVENTION
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention.
The question formats of the present invention are described in the context of the Integrated Reasoning (IR) section of the Graduate Management Admissions Test (GMAT®), administered by the Graduate Management Admissions Council, located in Reston, Va. The IR section was formally added to the GMAT exam in June 2012 so that the score on the IR section officially counts as a portion of the GMAT score since that date. However, the question formats of the present invention are not limited to the particular use in the GMAT exam and may be used on many other types of standardized tests.
Each of the items in the various question formats are presented to the user and scored via the same combination of hardware and software, shown in FIGS. 1 and 2. FIG. 1 shows a system flowchart 100 and FIG. 2 shows system hardware/software architecture 200. Referring to FIGS. 1 and 2, a processor 202 retrieves an item from storage 204 and displays the item on user-interface display screen 206 (step 100). A user response is received from user (test-taker) 208 and the response is sent to a response engine 210 (step 104). There will be multiple response opportunities for each item, and thus there will be multiple responses for each item. If there are more items to be presented to the user 208, then the next item is retrieved from the storage 204 and is presented to the user (“YES” output of decision block 106, step 102). If there are no more items to be presented to the user 208, then the responses are ready to be scored (“NO” output of decision block 106). A scoring engine 210 receives the responses from the response engine and scores the responses using scoring rules 214 (step 108). A scoring transformation 216 converts the score from a raw score to a scaled score (step 110).
In one preferred embodiment, the response engine 210 and the scoring engine 212 each have their own processor (not shown) which is separate from the processor 202 which controls the presentation of items on the user-interface display screen. However, other embodiments, one or more of the processors may be shared, such as the processor 202 and the processor associated with the response engine 210.
The IR section is only one of a plurality of sections of the GMAT exam. Since exam scoring preferably occurs separately from the test-taking site, and a later point in time, the responses for the IR section and the other sections of the GMAT exam will typically be stored in a file (not shown) populated at the exam site or at a remote site in communication with the exam site. This file is then electronically communicated to the scoring engine 212 at a later point in time. In one embodiment, a user may be provided at the exam site with some form of a score derived from their responses. In this embodiment, a version of the scoring engine 210 may operate locally to provide instant feedback to the test-taker after completion of the GMAT exam. However, no official score is provided at the exam site, and the score may be in the form of a raw score, not a scaled score.
Exam scoring may also be performed by a different entity that the entity that administers the GMAT exam. For example, an independent GMAT-certified contractor may administer the GMAT exam, but the scoring may be performed by a different GMAT-certified contractor, or by GMAT directly. Accordingly, there will typically be a time-delay between exam taking and exam scoring, and there will also typically be a data file transfer of the stored responses between different entities who are responsible for exam administration and exam scoring.
Referring again to the scoring engine 212, the scoring rules operate as follows:
1. Determine whether the response selected for each response opportunity is correct.
2. Assign credit for the item only if each of the responses for each of the response opportunities is correct, and assign no credit for the item if at least one of the responses for each of the response opportunities is incorrect.
In this manner, no partial credit is given for an item. As discussed above, each response opportunity is independent of each other. In conventional exam scoring where there are multiple response opportunities for a given item, and wherein the response opportunities are independent from each other, each response opportunity is assigned credit or no credit, depending upon whether the response is correct or incorrect. Thus, in conventional exam scoring for items described herein, partial credit is given for an item.
There are known (prior art) types of multiple choice exams wherein multiple potential correct answers are permitted for a question related to an item (e.g., there may be five answers, and the test-taker is instructed to select all correct answers). Some of these exams are graded in a manner that does not provide partial credit, so that the test-taker must select all of the correct answers when given a response opportunity, and none of the incorrect answers when given the response opportunity, to receive credit. However, there is only one response opportunity for such a question (i.e., select all answers that apply triggers the response opportunity). If the test-taker correctly selects all of the answers on the next question for the item when given the response opportunity for the next question, then the test-taker gets credit for that question, regardless of how they scored on other questions related to the same item. The type of scoring used for these multiple choice/multiple potential correct answer tests is thus not the same type of scoring described in the present invention which assigns no partial credit when there are multiple response opportunities for an item and any one response for the item is incorrect. This is also referred to herein as scoring at the item level.
In one preferred embodiment of the present invention, there are four question formats, namely, graphics interpretation, two-part analysis, table analysis, and multi-source reasoning. A sample IR test section may have 12 items, generally evenly distributed among the four question formats (e.g., three items from each question format). An overview and detailed specifications for each of the four question formats is provided below.

An example of an Integrated Reasoning section of the GMAT exam which consists of 12 questions is provided below. Successive display screens are shown to illustrate the screens that the test-taker experiences. In the example below, responses are entered for each of the response opportunities. Some of the responses are correct and some are incorrect. An example of the scoring process using the responses given in the example
The test-taker is provided with the following instructions for this section:
The Integrated Reasoning section consists of four question types, which require you to analyze and synthesize data in different formats and from multiple sources.
i. Almost all question formats require multiple responses. Questions are designed to measure how well you integrate data to solve complex problems, so you must answer all parts of a single question correctly to receive credit.
ii. All answer choices for a single question are presented on the same screen. You must submit responses to all parts of the question before moving on to a new question on another screen. Once you answer a question, you may not go back and change the answer.
iii. Data presented in text are approximately 300 words or fewer.
iv. Answer options don't provide information or clues that will help you solve other questions.
v. One set of data is used for several Multi-Source Reasoning questions, but the questions are independent of one another—you won't have to answer one question correctly to be able to answer another.
Graphics Interpretation: Interpret the graph or graphical image and select the option from a drop-down list to make the answer statements accurate.
Two-Part Analysis: Select one answer from each column to solve a problem with a two-part solution. Possible answers will be presented in a table with a column for each part.
Table Analysis: Sort the table to organize the data so you can determine whether certain conditions are met. Each question will have statements with opposing answers (e.g., yes/no, true/false, inferable/not inferable); select one answer for each statement.
Multi-Source Reasoning: Click on the page to reveal different data and discern which data you need to answer the question.
FIGS. 8-12 show a succession of display screens for graphics interpretation items.
FIG. 8: This is the initial display screen for item 1 of 4.
FIG. 9: The user selects the first drop-down box and views the potential responses to the first response opportunity.
FIG. 10: The user selects the answer “5 of 6.”
FIG. 11: The user selects the second drop-down box and views the potential responses to the second response opportunity.
FIG. 12: The user selects the answer “2 out of 3” and hits the Next button to confirm the two responses.
The drop-down boxes can be selected and responded to in any order and the user may change the answer any point in time prior to hitting the Next button.
The process described in FIGS. 8-12 is repeated for the remaining graphics interpretation items. FIGS. 13 and 14 shows selected display screens for another graphics interpretation item.
FIG. 13: This is the initial display screen for item 3 of 4. (The display screens for Item 2 of 4 were skipped in this illustration.)
FIG. 14: The user selects the first drop-down box and views the potential responses to the first response opportunity.
FIG. 15: The user selects the second drop-down box and views the potential responses to the second response opportunity.
FIGS. 16-18 show a succession of display screens for two-part analysis items.
FIG. 16: This is the initial display screen for item 1 of 5. (There would not likely be five items of this type since there are only 12 total items.)
FIG. 17 shows the user's two responses made to the two response opportunities for item 1 of 5.
FIG. 18 shows the user's two responses made to the two response opportunities for item 4 of 5.
FIGS. 19-23 show a succession of display screens for table analysis items.
FIG. 19: This is the initial display screen for item 1 of 3.
FIG. 20: The user selects the drop-down box for sorting of the table by column values.
FIG. 21: The user has selected to sort by “Production, world rank.” The table now appears differently than it did in the initial display screen of FIG. 19.
FIG. 22: The user has selected to sort by “Exports, world rank.” The table now appears differently than it did in the initial display screen of FIG. 19 and the display screen of FIG. 21. The user has also made responses to the two response opportunities and is ready to select the Next button to confirm the responses. In a typical scenario, the user will repeatedly re-sort the table while deciding which responses to select for the two response opportunities. Any responses that were made remain selected even if the user performs additional table resorting. The responses can be changed at any time prior to selecting the Next button.
FIG. 23: This is the initial display screen for item 2 of 3.
FIGS. 24-27 show a succession of display screens for multi-source reasoning items.
FIG. 24: This is the initial display screen for item 1 of 7. (Again, there would not likely be seven items of this type since there are only 12 total items.)
The stimulus information is Email #1.
FIG. 25: The user clicks on Email #2 which changes the stimulus information to Email #2.
FIG. 26: The user clicks on Email #3 which changes the stimulus information to Email #3. The user has also made responses to the two response opportunities and is ready to select the Next button to confirm the responses. The user can also re-review the other emails before deciding on the responses. Any responses that were made remain selected even if the user goes back to review other emails. The responses can be changed at any time prior to selecting the Next button.
FIG. 27: This is the initial display screen for item 2 of 7.
FIG. 28: This is the initial display screen for item 5 of 7. Note that the stimulus information for items 2 of 7 and 5 of 7 is the same. (The stimulus information for items 3 of 7 and 4 of 7 would also be the same in this example.) However, the statements and response opportunities differ for each item.
The table below shows a sample score tally and the corresponding raw score. The comments are for explanatory purposes only and would not appear in the table in this format. However, all of the responses would be electronically recorded. Except for item 1, the table does not reflect the succession of display screens described above.

score









Raw scores are transformed (converted) to scaled scores using a transformation process.
The raw score of the IR section is the sum of all the item (question) scores but the raw scores are not the scores reported to the test-takers (users). The reported scale ranges from 1 to 8 and the scaled score of the IR section is derived from a conversion of the raw score.
Most high-stakes test programs utilize multiple test forms in one test administration or different test forms for different test administrations as a measure of test security. Despite the endless effort to minimize the differences in the process of assembling multiple parallel test forms, the resultant forms might vary slightly in difficulty. A statistical procedure is performed to adjust the raw scores for the minor differences in the difficulty. The statistical procedure, known as “equating,” ensures that all the scores from all test forms are comparable. A conversion table for each test form resulted from the equating procedure includes a mapping of raw to scaled scores. In practice, the conversion becomes a simple table consultation to find the corresponding scaled score for a raw score.
There are a variety of equating methods. One preferred method for use in the IR section is the “equipercentile equating method.” Many other methods could be used for this purpose and the present invention is not limited to this particular equating method.
FIG. 29 is a flowchart of the IR scoring process 2800. The steps of the flowchart are implemented in a computer program environment, and are summarized as follows:
Select item—2802
Present item to candidate and capture response—2804
Analyze item response—2806
Select response opportunity—2808
Analyze response opportunity—2810
Score the response value as either correct (“1”) or not correct (“0”)—2812, 2814, 2816
If all response opportunities have not been scored, select the next response opportunity and score it —2818, 2820 and repeat 2806-2810
If all response opportunities have been scored, check whether all response opportunities for the item were correct and assign an item score of “1” or “0” depending upon the result —2822, 2824, 2826
If there are more items to score, select the next item and repeat the steps above —2828, 2830
If there are no more items to score, calculate the IR section raw score which is the number of items with an item score equal to “1”—2832
Calculate the IR section scaled score using a conversion table to map the raw score to the scaled score —2834
FIG. 30 show a perceptual map of the data structure of the IR section 2900 which includes a plurality of IR items 29021-2902n and a plurality of IR response opportunities 29041-2904n.
FIGS. 31-33 show the IR section data structure at the data value level. FIG. 31 shows the section data, FIG. 32 shows the item data, and FIG. 33 shows the response opportunity data.
