This paper reports the results of an experiment designed to investigate the effectiveness of different collaborative group formations (homogeneous vs. heterogeneous in terms of prior computer knowledge levels) for learning complex tasks in computer programming from the perspective of cognitive load theory. Web-based learning platform was used to…

The Java Intelligent Tutoring System (JITS) was designed and developed to support the growing trend of Java programming around the world. JITS is an advanced web-based personalized tutoring system that is unique in several ways. Most programming Intelligent Tutoring Systems require the teacher to author problems with corresponding solutions. JITS,…

In this article we present a structured set of Design Patterns (DPs) that deals with tracking students while they solve problem in specific domains such as programming or mathematics. Our collection of 17 DPs yields a three step approach: First step: to collect and analyze information on each student for each exercise; Second step: to build a…

Discusses how the design and implementation of problem-solving tools used in programming instruction are complementary with both the theories of problem-based learning (PBL), including constructivism, and the practices of distributed education environments. Examines how combining PBL, Web-based distributed education, and a problem-solving…
