In this study, the authors have developed a web-based programming exercise system currently implemented in classrooms. This system not only provides students with a web-based programming environment but also tracks the time spent on exercises, logging operations such as program editing, building, execution, and testing. Additionally, it records…

The gender gap in computer science is worst amongst any of the STEM fields. At the secondary school level, only 18.6% of AP computer science test-takers in the United States were girls. In order to address the persistent gender gaps in computer science, it is important to understand K-12 students' views about computer science and programming. The…

In a course of the degree of computer science, the programming project has changed from individual to teamed work, tentatively in couples (pair programming). Students have full freedom to team up with minimum intervention from teachers. The analysis of the working groups made indicates that students do not tend to associate with students with a…

We developed the Draw-A-Computer-Scientist-Test (DACST) to better understand elementary school students' conceptions of computer scientists and the nature of their work. By understanding how young children perceive computer scientists, we can broaden their ideas about the activities and images of computer scientists. We administered the DACST to…

Effective mining of data from online submission systems offers the potential to improve educational outcomes by identifying student habits and behaviours and their relationship with levels of achievement. In particular, it may assist in identifying students at risk of performing poorly, allowing for early intervention. In this paper we investigate…

Making construals is a practical approach to computing that was originally developed for and by computer science undergraduates. It is the central theme of an EU project aimed at disseminating the relevant principles to a broader audience. This involves bringing together technical experts in making construals and international experts in…

While many technical disciplines have reached or are moving toward gender parity in the number of bachelors degrees in those fields, the percentage of women graduating in computer science remains stubbornly low. Many recent efforts to address this situation have focused on retention of undergraduate majors or graduate students, recruiting…

The iDREAMS project aims to reinvent Computer Science education in K-12 schools, by using game design and computational science for motivating and educating students through an approach we call Scalable Game Design, starting at the middle school level. In this paper we discuss the use of Computational Thinking Patterns as the basis for our…

This paper describes a National Science Foundation-sponsored project at Louisiana Technological University to develop computer-based laboratories for "hands-on" introductions to major topics of computer science. The underlying strategy is to develop structured laboratory environments that present abstract concepts through the use of…
