Computer science for high school faces many challenging issues. One of these is whether the students possess the appropriate cognitive ability for learning the fundamentals of computer science. Online tests were created based on known cognitive factors and fundamental algorithms and were implemented among the second grade students in the…

Abstraction is a key concept in CS, one of the most fundamental ideas underlying CS and its practice. However, teaching this soft concept to novices is a very difficult task, as discussed by many CSE experts. This paper discusses this issue, and suggests a general framework for teaching abstraction in CS to novices, a framework that would fit into…

From 2004-2007, the University of Memphis carried out the NSF-funded Tri-P-LETS (Three P Learning Environment for Teachers and Students) project to improve local high-school computer science curricula. The project reached a total of 58 classrooms in eleven high schools emphasizing problem solving skills, programming concepts as opposed to syntax,…

Nondeterminism is an essential concept in mathematics and one of the important concepts in computer science. It is also among the most abstract ones. Thus, many students find it difficult to cope with. In this article, we describe some didactic considerations, which guided the development of a "Computational Models" course for high school…

Worldwide surveys indicate that the number of women studying undergraduate-level Computer Science is constantly decreasing. Based on data collected in Israel, significant differences were found in the percentages of female high school students studying advanced-level Computer Science among different sectors. More specifically, while the percentage…

Computer Science formal education brings together old-timers from two computer-literate cultures. The curriculum is oriented toward the academic community, whose interest is in the abstraction, solution, and proofs of algorithmic problems, whereas many students are technology users, whose main interest is the manipulation of the products of…
