Benefits andefficiency of robotics in teaching and learning processes have recently been drawing an increasing focus among researchers.Application of robotics is useful for students while studying Computer Engineering and other STEM (Science,Technology, Engineering and Mathematics) subjects. The article pursues twofold research aim: (1) to perform systematicreview of the literature on application of educational robots in schools in order to identify the experience in use of roboticsin primary, basic and secondary schools, and (2) to conduct empirical study in Lithuania on the attitude towards use ofrobotic technologies in education, the related experience and demand, and identify the causes of low use of robotics inteaching and learning. Systematic literature review has shown that robotics has been paving its way as a teaching aid in amore intensive and flexible manner. The findings of empirical study have demonstrated the potential in use of robotictechnologies and current related implications in Lithuanian schools

Both the learning software 'internal quality' and 'quality in use' technological evaluation criteria are analyzed in the chapter and are incorporated into comprehensive quality evaluation models. The learning software quality evaluation criteria are further investigated in terms of their optimal parameters, and an additive utility function based on experts' judgements, including multicriteria evaluation, numerical ratings, and weights, is applied to optimize the learning software according to particular learners' needs.

The maturity exam in informatics was established in 1995, although its content has been changed several times since then. This paper analyzes the conception of the maturity exams in informatics and provides explanations of the examination’s structure, content, and goals. Exams in informatics have a double mission: to evaluate students’ knowledge and skills and to encourage teachers and students toward the study of informatics. Considering that programming as a branch is fairly important to the state’s economy, the decision was made to establish a special exam in programming. This paper presents the results of the pilot exam in programming.

Teaching of programming is an important part of different Informatics Engineering, ComputerScience or Informatics, Computing, Information Technology and Communication courses in Universities and high schools.Students taking these courses have to demonstrate competences in problem solving and programming by creating workingprograms. Checking program validity is usually based on testing a program on diverse test cases. Testing for batch-type problemsinvolves creating a set of input data cases, running a program submitted by a contestant with those input cases, analysing obtainedoutputs, etc. Assessment of programming assignments is as complex as testing of software systems. A lot of automatic assessmentsystems for programming assignments have been created to support teachers in submission assessment. However the problem ofbalance between the quality and the speed of assessment for programming assignments is important. Authors conducted theresearch on the possibilities of advanced semi-automatic approach in assessment, which can be used as compromise betweenmanual and automatic assessment. A semi-automatic testing environment for evaluating programming assignments is developed,and the practical use of this system in Lithuania’s optional programming maturity examination is presented. Presented research isuseful for evaluating results of engineering education in general, and informatics/computer engineering education particularly.

The authors’ approach consists of the consecutiveapplication of the principles of multiple criteria decision analysis for identifying the VLEs adaptation quality criteria, setsportrait method to analyse the interconnections of the VLE adaptation quality criteria and the learners’ computationalthinking skills, fuzzy group decision making theory to obtain final evaluation measures of the VLEs quality criteria, andscalarization method to obtain the final results of evaluating the VLEs quality. While applying these methods, appropriatedecision support system was developed. This system consists of the learners’ computational thinking skills’ questionnaires,observations results and conclusions, VLEs adaptation quality criteria, their ratings (values) and weights, and finalevaluation results that propose a proper decision. This approach should help Universities and schools to create, buy, orfind free VLE software mostly suitable for teaching and learning Informatics. Computational thinking term is detailed inthe paper, and interconnected with the VLEs adaptation quality criteria using sets portrait method. After that, multiplecriteria decision analysis approach is used to evaluate the adaptation quality of VLE in terms of its conformance with thelearners’ computational thinking styles. The experts’ additive utility function is proposed to use for the expert evaluation ofthe adaptation quality of VLEs. Trapezoidal fuzzy numbers method is proposed to use for establishing both weights andratings (values) of the VLEs quality criteria matching learners’ computational thinking styles. Practical example of theexperimental evaluation of three popular open source VLEs is also presented in the paper. Presented research results areparticularly useful for Informatics/software engineering education.
