Informatics in Education

The choice of programming language for education is an intensely debated topic. On the one hand, the programming language is supposed to be relevant in that its organisation, structures, and paradigms adhere to current standards and best practices in industry and academia. On the other hand, the programming language is expected to be simple, that is, easy to use and, of course, easy to learn. This increasingly means that we need an introduction to concepts shaped by a long history without all the historic baggage.

Preparing students for the workforce is a balancing act that involves theory, practice, and assessment. As students navigate an educational experience that is, however, often distant from real-world needs, it is imperative that academia finds a novel way to bridge the gap. As many organizations utilize open challenges to attract ideas and talent, academia can easily create such bridge, leading to greater engagement, greater student preparation, and a potential employment pipeline. This paper describes the experience of our students and faculty advisors who participated to the NASA SUITS (Spacesuit User Interface Technologies for Students) Design Challenge. In particular, we review the pedagogical value of the solution that they created and the changes that were implemented in the curriculum of an undergraduate degree program in Information Technology. This open-source, multi-year project is also a flexible platform that can be utilized for engagement in K-12 education as well as graduate research projects.

Programming is one of the most important aspects of a Computing course. Teaching programming is a challenging task due to a number of factors, ranging from lack of student problem solving skills to different teaching methods. This paper focuses on Maltese Computing teachers’ perspectives about the difficulties encountered when teaching programming to secondary school students in order to determine whether introducing programming to secondary school students through creating mobile-based games is an effective method to teach programming constructs. A resource pack consisting of various activities using MIT App Inventor 2 was created which incorporated constructivist approaches to teaching. This resource pack was reviewed by the teachers and their feedback was collected by means of a case study. The teachers agreed that developing mobile-based games would be highly stimulating to their students but there were uncertainties how this would affect students with different learning abilities and due to a general lack of computational thinking and problem-solving skills by most students.

Programming is one of the basic subjects in most informatics, computer science mathematics and technical faculties' curricula. Integrated overview of the models for teaching programming, problems in teaching and suggested solutions were presented in this paper. Research covered current state of 1019 programming subjects in 715 study programmes at total of 218 faculties and 143 universities in 35 European countries that were analyzed. It was concluded that while most of the programmes highly support object-oriented paradigm of programming, introductory programming subjects are mainly based on imperative paradigm.

Nondeterminism (ND) is a fundamental concept in computer science, and comes in two main flavors. One is the kind of ND that appears in automata theory and formal languages, and is the one that students are usually introduced to. It is known to be hard to teach. We present here a study, in which we introduced students to the second kind of ND, which we term operative. This kind of ND is quite different from the first one. It appears in nondeterministic programming languages and in the context of concurrent and distributed programming. We study how high-school students understand operative ND after learning the nondeterministic programming language of live sequence charts (LSC). To assess students' learning, we used a two-dimensional taxonomy that is based upon the SOLO and the Bloom taxonomies. Our findings show that after a semestrial course on LSC, high-school students with no previous experience with ND of either type, understood operative ND on a level that allowed them to create and execute programs that included nondeterminism on various levels and in various degrees of complexity. We believe that it is important to expose students to the two types of ND, especially as ND has become a very prominent characteristic of computerized systems. Our findings suggest that students can reach a significant understanding of operative ND when the concept is introduced in the context of a programming course.
