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.
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.
The technological resources used for pedagogical innovation in the form of distance education have increasingly been incorporated into face-to-face education. This article describes the experience of the Federal University of Lavras - Brazil - with new ways to apply technology in face-to-face undergraduate courses. This paper presents (i) the strategy for the selection of course content, which was premised on the diversification of areas of knowledge and on promoting the permanent incorporation of the resources developed in the teaching-learning process, (ii) the organization of the production process of Learning Objects based on the Scrum method, (iii) the set of best practices, inspired by the management of agile software development, as well as the contextual motivation of its use.
The introduction of the intelligence in teaching software is the object of this paper. In software elaboration process, one uses some learning techniques in order to adapt the teaching software to characteristics of student. Generally, one uses the artificial intelligence techniques like reinforcement learning, Bayesian network in order to adapt the system to the environment internal and external conditions, and allow this system to interact efficiently with its potentials user. The intention is to automate and manage the pedagogical process of tutoring system, in particular the selection of the content and manner of pedagogic situations. Researchers create a pedagogic learning agent that simplifies the manual logic and supports progress and the management of the teaching process (tutor-learner) through natural interactions.
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 presents the results of an international research on a comparative assessment of the current status of computer science education at the secondary level (ISCED 3A) in Slovakia, the Czech Republic, and Belgium. Evaluation was carried out based on 14 specific factors gauging the students' point of view. The authors present qualitative findings from the following nine analyzed factors: the popularity of computer science/informatics as a subject, the potential of using knowledge gained by studying informatics at school in everyday life, the attractiveness and demands of the curriculum content, the clarity and attractiveness of teacher presentation of the subject matter to students, the engagement of tasks solved while studying informatics, the degree of comprehensibility of informatics textbooks, and the usability of knowledge acquired in school for solving practical problems. Based on the results, the authors identify the strengths and weaknesses of computer science education in the observed countries.
The paper analyses the problems in selecting and integrating tools for delivering basic programming knowledge at the university level. Discussion and analysis of teaching the programming disciplines, the main principles of study programme design, requirements for teaching tools, methods and corresponding languages is presented, based on literature overview and author`s experience. A pressure from labor market, students and other sources to emphasize practical skills over deeper, long-term programming concepts is described. A model of teaching introductory programming disciplines at a higher logical level, using C#, is presented as a summary of the accomplished analysis, and also taking into account the recommendations of the ACM (Association for Computing Machinery) association for typical teaching programs. Also, design principles for building introductory programming courses, aligned with such teaching approach, are presented. This model has already been trialed at Vytautas Magnus University.
The paper analyses the results of the computer literacy survey conducted among the 11th and 12th form students in gymnasiums and secondary schools in Lithuania. The basis for the questionnaire was taken from previous surveys carried out in Vilnius Pedagogical University. The questionnaire is divided into five topics, such as computer hardware and software, information handling, text and hypertext, the Internet, spreadsheets and presentations. The following article discusses only the first three topics.
The data was collected from April to September 2010 through an online survey internet site www.apklausa.lt. The sample of the survey includes 1596 students from Lithuania.
The aims of the paper are to record students' knowledge about information technologies, explore the main topics and recommend improvements for the discipline of information technologies.
This paper discusses some difficulties in teaching introductory courses to programming, paying particular attention to their mathematical nature. We consider some aspects, which have not been commented in detail in textbooks and often neglected by course outlines and schedules. Some of these are constructing complex conditions, exceeding array bound, calculating infinite series in conjunction with recursion, etc. We believe that those topics and accompanying notes along with appropriate teaching methodology could be and should be incorporated into introductory programming courses.
Many factors influence education nowadays. Educational institutions are faced with budget cuttings, outdated IT, data security management and the willingness to integrate remote learning at home. Virtualization technologies provide innovative solutions to the problems.
The paper presents an original educational infrastructure using virtualization technologies implemented in a training process at Kaunas University of Technology. This infrastructure allows university students and staff to access virtual desktops and applications via Web, both in computer classes at the University, and for self-working at home. This paper introduces virtualization technologies of the implemented infrastructure highlighting the benefits, outlines functions of the infrastructure and presents research experiments of network load monitoring that have been performed to find out problems of the infrastructure.
