This study presents a new blended learning model that combines a computer-assisted learning system called Cognitive Apprenticeship Programming Learning System (CAPLS) with instructor co-teaching in an introductory programming course. CAPLS, as its unique aspect, functions as a master in cognitive apprenticeship, guiding learners throughout their…

Computer-graders have been in regular use in the context of MOOCs (Massive Open Online Courses). The automatic grading of programs presents an opportunity to assess and provide tailored feedback to large classes, while featuring at the same time a number of benefits like: immediate feedback, unlimited submissions, as well as low cost of feedback.…

Programming assignments are commonly used in computer science education to encourage students to practice target concepts and evaluate their learning status. Ensuring students are engaged in such assignments is critical in attracting and retaining students. To this end, WebHat, a service-based program evaluation platform, is introduced in this…

Teachers usually expect that any form of a continuous assessment (CA) should contribute significantly to the student learning process in introductory programming courses. To foster teachers to go beyond the current practices of a CA applied when to programming, from 2011 to 2014, we investigated the use of the Boca Online Contest Administrator…

It is a hard task to strike a balance between extents of control a learner exercises and the amount of guidance, active or passive, afforded by the learning environment to guide, support, and motivate the learner. Adaptive systems strive to find the right balance in a spectrum that spans between self-control and system-guidance. They also concern…

Creative Commons (CC) mechanism has been suggested as a potential means to foster a reliable environment for online knowledge sharing activity. This study investigates the role of the CC mechanism in supporting knowledge sharing among a group of university students studying programming from the perspectives of social cognitive and social capital…

Based on a three-semester design research study, this paper argues the need to redesign online learning environments to better support the representation and sharing of factual, procedural, and conceptual knowledge in order for students to develop their design capabilities. A web-conferencing environment is redesigned so that the modalities…
