Artificial Neural Networks (ANN's) are nowadays a common subject in different curricula of graduate and postgraduate studies. Due to the complex algorithms involved and the dynamic nature of ANN's, simulation software has been commonly used to teach this subject. This software has usually been developed specifically for learning purposes, because the existing general packages often lack of a convenient user interface, and are too complex or inadequate for these goals. Since ANN's algorithms, types and applications grow regularly, this solution becomes more and more complex and inefficient. In this paper, we present Visual NNet, a learning-oriented ANN's simulation environment, which overcomes this problem by reusing Matlab Neural Networks Toolbox (MNNT), a well-known, comprehensive and robust ANN implementation. Visual NNet combines an on-purpose learning oriented design with the advantages of an ANN's implementation like MNNT. Furthermore, reusing MNNT has done Visual NNet development more cost-effective, fast and reliable.

Automatic program evaluation is a way to assess source program files. These techniques are used in learning management environments, programming exams and contest systems. However, use of automated program evaluation encounters problems: some evaluations are not clear for the students and the system messages do not show reasons for lost points. The author proposes several ideas for possible improvements in black box testing, which can lead into better service for the users of automatic evaluation systems.
Invariant Based Programming in Education--An Analysis of Student Difficulties

In this paper, we analyze the errors novice students make when developing invariant based programs. In addition to presenting the general error types, we also look at what students have difficulty with when it comes to expressing invariants. The results indicate that an introductory course utilizing the invariant based approach is suitable from the very beginning of university studies in CS without being &quot;too advanced&quot;. Although inventing the invariant was not found to be trivial, the main difficulty faced by novices when applying a correct-by-construction approach to program development seems to be related to weak skills in translating intuitive and informal statements into a symbolic form using logical notation in general and quantifiers in particular.

In order to improve the learning process for students with different pre-knowledge, personal characteristics and preferred learning styles, a certain degree of adaptability must be introduced to online courses. In learning environments that support such kind of functionalities students can explicitly choose different paths through course contents or can be directed to different parts of the instructional material depending on the pace of their advancement in acquiring new knowledge. This paper presents the implementation of such an environment by extending open source learning management system Moodle.

This work investigates the effect of computer use in the memory process in young and adults under the Perceptual and Memory experimental conditions. The memory condition involved the phases acquisition of information and recovery, on time intervals (2 min, 24 hours and 1 week) on situations of pre and post-test (before and after the participants took part on a Basic Computing course), in which the participants studied the map of Brazil during 7 minutes and the estimates of different areas of Brazilian states were performed according to the magnitude estimation method, without the presence of the map. On the Perceptual condition, the estimates were made in the presence of the Brazilian map. The study made possible to verify that the use of a computer, as a new activity enables a differentiation on the memory process in relation to the different experimental conditions proposed and to the time intervals used between acquisition, processing and information recovery, showing that the use of a computer as a pedagogical tool may promote the improvement of the memory process in academic activities.

The paper elaborates on experiences and lessons learned from the course on object-oriented analyses and design at the Faculty of Sciences, Novi Sad. The course on OOAD is taught to students of computer science and to the students of mathematical programme. Conclusions made in this paper are based on results of students' assignments as well as results of conducted survey. In the paper we identify a set of issues concerning teaching modelling and UML. It is noticed that difficulties in mastering OOAD arise primarily from the absence of appropriate real case studies from the field of designing information systems. In order to overcome this problem, students worked on their own homework projects which include all phases of software development. Concerning the results of survey it is noticed that OOAD course should be taught in different manners regarding previous knowledge of students. Suggestions how to teach OOAD to students of computer science and to students of other programmes are given in this paper.

C++ is the most commonly used language in introductory and intermediate programming courses in Bulgarian universities. In recent years this language has developed greatly. Its abstractions are more flexible and affordable than ever before. Such great number of changes are related to the launch of the new standard (known as C++11) that we have grounds to consider it even a new language. It is inevitable to reflect all these changes in training courses and this prompted us to consider not only some updating of academic curricula but also a comprehensive reorganization of our programming courses. So, in this article we share our successes and difficulties in this direction.

While researchers working within the &quot;Student Learning Research&quot; framework have developed or adapted questionnaires to gather information on students' experiences of blended learning, no questionnaire has been developed to enquire about teachers' experiences in such learning environments. The present article reports the development and testing of a novel questionnaire on &quot;approaches to e-teaching,&quot; which may be employed to investigate the experience of teaching when e-learning is involved. Results showed suitable reliability and validity. Also, when exploring associations between the novel questionnaire scales and those of the well-known &quot;approaches to teaching&quot; inventory (Prosser and Trigwell, 2006), results from correlation and cluster analyses suggest that student-focused approaches to teaching are needed for significant use of digital technology to emerge. For practice, this relevant outcome implies that teaching needs to be considered holistically when supporting teachers to incorporate e-learning in their practice: because it seems they approach online teaching coherently with the face-to-face side of the blended experience.

In this paper, we propose the development of a web-based, intelligent instruction system to help elementary school students for mathematical computation. We concentrate on the intelligence facilities which support diagnosis and advice. The existing web-based instruction systems merely give information on whether the learners' replies are &quot;correct&quot; or &quot;incorrect,&quot; and only offer evaluations of the learners' results in terms of points. What is needed is a web-based instruction system that diagnoses the learner's comprehension status, and provides cause: why did the learner make the error? Our system has a facility that analyses the learner's weak points and has the ability to diagnose the cause of the error, giving advice to the learners and more detailed error information than extant systems. By accumulating user behavior and analyzing the learner's responses, our system provides relevant, individualized information, along with advice for the learners.

With a significant increase in the number of e-learning resources the issue of quality is of current importance. An analysis of existing scientific and methodological literature shows the variety of approaches, methods and tools to evaluate e-learning materials. This paper proposes an approach based on the procedure for estimating parameters of local factors and receiving the integral index of usability quality of e-learning modules. We present a mathematical model which serves as a basis for the automated procedures for expertise. The use of fuzzy logic allows to reduce greatly the complexity of evaluating the formation of a repository of e-learning modules. The proposed approach is focused on the situation, when the university: (1) has amassed a large number of e-learning modules that have to be assessed in terms of ergonomics; (2) is able to use experts in ergonomics and organization of e-learning (the experts can provide, as a rule, qualitative assessment); (3) is limited in resources on the development of special software for evaluation of e-learning modules; and (4) is forced by the need to reduce the cost of expertise to be limited to considering only the main quality indicators that have the greatest impact on the ergonomics of e-learning modules. For automation of the ergonomic examination procedures a MatLab system is used, in particular Fuzzy Logic Toolbox. Application of the well-known mathematical tools and widely used means of processing expert qualitative assessments can significantly reduce the cost of the expertise.

The paper's contribution is a methodology that integrates two educational technologies (GLO and LEGO robot) to teach Computer Science (CS) topics at the school level. We present the methodology as a framework of 5 components (pedagogical activities, technology driven processes, tools, knowledge transfer actors, and pedagogical outcomes) and interactions among the components. GLOs are meta-programmed entities to generate LO instances on demand depending on the context of use and learning objectives. A GLO is a black-box entity, which is integrated in the framework through the generating process to source the teaching and learning process via robot-based visualization to demonstrate how programs and algorithms are transformed into real-world tasks and processes. The methodology is tested in the real e-learning setting. The pedagogical outcomes are evaluated by empirical data showing the increase of student engagement level, higher flexibility and reuse enhancement in learning.

The Semantic Web is an extension of the current Web where information is represented in a machine processable way. It is not separate from the current Web and one of the confusions that novice users might have is where the Semantic Web is. In fact, users can easily encounter RDF documents that are components of the Semantic Web while they navigate among Web pages. In addition, the number of RDF documents on the Web is ever-increasing and a lot of educational materials in RDF format become available on the Web. In this paper, we propose a simple Semantic Web browser by which non-expert users such as secondary school students who do not know technical details about the Semantic Web can browse through HTML documents and RDF documents.

With the advance of information and communications technologies, new teaching tools are becoming more pervasive. These tools can be utilized in a variety of ways to improve and enhance math teaching. Considering the integration of technology in teaching mathematics, it is clear that the replacement of board and chalk with digital presentation material does not cover all the aspects of the mathematic subjects. One of the important prerequisites for quality of integration technology into mathematics teaching is the teacher's personality, i.e. knowledge, willingness and desire to improve his/her lessons bringing mathematics closer to the present generations of pupils. GeoGebra as a dynamic mathematics software allows users to explore multiple representations of mathematics concepts. The paper deals with the problem of deployment of GeoGebra in Lithuanian's primary math education and the main purpose of this study is to investigate reasons/factors affecting teachers' decision to utilize GeoGebra and learning objects prepared by it in their teaching process. With a view to evaluate GeoGebra's suitability to primary education an expert opinion poll was conducted and results of that exploratory study are presented.

There are many important issues in informatics and many agree that algorithms and programming are most important issues that need to be included in informatics education (Dagiene and Jevsikova, 2012). In this paper, we propose how some of these issues can be easily taught using the notion of a formal system which consists of axioms and inference rules by which theorems can be proved. As is argued in (Dagiene and Jevsikova, 2012), we can introduce important topics in informatics using puzzle-like examples and students do not need to have prerequisites for learning. The materials presented in this paper have been used in a college-level elective class titled Hypertext and Computability in our university since the fall semester of 2008 and we believe that the contents proposed in this paper can be easily used to teach beginner students without technical backgrounds.

Mathematics' skills and knowledge lay the basis for engineering studies. However, the resources targeted to mathematics' teaching are in many cases very limited. During the past years in our university the reduction of mathematics' contact hours has been significant while at the same time the study groups have grown. However, the mathematical proficiency of incoming students has not increased. Consequently, during the contact hours, the learning of basics requires more time and the need of personalized learning is increasing. In this article a method based on short video lecturing to enhance mathematics' learning is presented. The study explored how the students experienced the mathematics' studying from videos. In addition, it was investigated if the video lectures have an influence on students' motivation towards mathematics' learning. Overall, the results were encouraging and the short video lecturing seems to be worth considering while developing methods for mathematics' learning. This paper summarizes the observations during the examination.

The aim of this work is to adapt and test, in a Brazilian public school, the ACE model proposed by Borkulo for evaluating student performance as a teaching-learning process based on computational modeling systems. The ACE model is based on different types of reasoning involving three dimensions. In addition to adapting the model and introducing innovative methodological procedures and instruments for collecting and analyzing data, our main results showed that the ACE model is superior than written tests for discriminating students on the top and bottom of the scale of scientific reasoning abilities, while both instruments are equivalent for evaluating students in the middle of the scale.

This paper proposes a student-oriented approach tailored to effective collaboration between students using mobile phones for language learning within the life cycle of an intelligent tutoring system. For this reason, in this research, a prototype mobile application has been developed for multiple language learning that incorporates intelligence in its modeling and diagnostic components. One of the primary aims of this research is the construction of student models which promote the misconception diagnosis. Furthermore, they are the key for collaboration, given that students can cooperate with their peers, discuss complex problems from various perspectives and use knowledge to answer questions and/or to solve problems. Summarizing, in this paper, a mobile tutoring framework, built up in the context of student collaboration, is presented. Collaborative student groups are created with respect to the corresponding user models. Finally, the prototype was evaluated and the results confirmed the usefulness of collaborative learning.
