Alexandron, Giora; Armoni, Michal; Gordon, Michal; Harel, David – ACM Transactions on Computing Education, 2014
In this article, we discuss the possible connection between the programming language and the paradigm behind it, and programmers' tendency to adopt an external or internal perspective of the system they develop. Based on a qualitative analysis, we found that when working with the visual, interobject language of live sequence charts (LSC),…

Armoni, Michal; Gal-Ezer, Judith; Hazzan, Orit – Computer Science Education, 2006
This paper discusses the role of reduction in computer science and describes a study on undergraduate students' perception of the concept of reduction. Specifically, based on an analysis of students answers to questions addressing different computer science topics, we present several findings regarding the ways in which undergraduate students…

Armoni, Michal; Gal-Ezer, Judith – Mathematics and Computer Education, 2005
When dealing with a complex problem, solving it by reduction to simpler problems, or problems for which the solution is already known, is a common method in mathematics and other scientific disciplines, as in computer science and, specifically, in the field of computability. However, when teaching computational models (as part of computability)…
