The Friends of the Pikes Peak Library District (PPLD) had a legacy website that was remotely hosted and maintained by a volunteer. They wanted a more significant presence on PPLD.org and an easier interface with which to update information. The developers decided to create a new Friends site in Drupal, using RWD, CSS3, and HTML5. The plan was to…

Constraint satisfaction problems are a powerful way to abstract and represent academic and real-world problems from both artificial intelligence and operations research. A constraint satisfaction problem is typically addressed by a sequential constraint solver running on a single processor. Rather than construct a new, parallel solver, this work…

Link failures in wide area networks are common and cause significant data losses. Mesh-based protection schemes offer high capacity efficiency but they are slow, require complex signaling, and instable. Diversity coding is a proactive coding-based recovery technique which offers near-hitless (sub-ms) restoration with a competitive spare capacity…

Authorship attribution of source code is the task of deciding who wrote a program, given its source code. Applications include software forensics, plagiarism detection, and determining software ownership. A number of methods for the authorship attribution of source code have been presented in the past. A review of those existing methods is…

As the so-called "digital natives" of the 21st century, children's fluency with web-based technologies is often assumed to be the natural and inevitable extension of living on a "new digital frontier". However, a growing body of research is increasingly questioning this widespread assumption about children's capacity…

IMS Learning Design (LD) is the only available interoperability specification in the area of technology enhanced learning that allows the definition and orchestration of complex activity flows and resource environments in a multirole setting. IMS LD has been available since 2003, and yet it has not been widely adopted either by practitioners or by…

Much application software education in Taiwan can hardly be regarded as practical. The researchers in this study provided a flexible means of ubiquitous learning (u-learning) with a mobile app for students to access the learning material. In addition, the authors also adopted computational thinking (CT) to help students develop practical computing…

Pair programming (PP) is a useful approach to fostering computational thinking for young students. However, there are many factors impacting on the effectiveness of PP. The period of switching roles between the driver and the navigator is often ignored by researchers. Therefore, this study aimed to explore the impact of the switching period on PP.…

In this paper, we describe the design and implementation of computer programming activities aimed at introducing young students (9-13 years old) to the idea of infinity, and in particular, to the cardinality of infinite sets. This research was part of the "WebLabs" project where students from several European countries explored topics in…

This paper presents the history of algorithm visualization (AV), highlighting teaching-methodology aspects. A combined, two-group pedagogical experiment will be presented as well, which measured the efficiency and the impact on the abstract thinking of AV. According to the results, students, who learned with AV, performed better in the experiment.

The purpose of this study was to investigate the influence of goal specificity and scaffolding on the programming performance and self-regulation of elementary students engaged in learning game design. This study recruited 232 students for the experimental activities. Two levels of goal specificity were employed: specific and nonspecific.…

The purpose of the present study was to investigate if we could improve retention by redesigning an online programming course from a gender perspective, while maintaining the focus on preferable and sustainable learning approaches. The study builds on results from an earlier study that investigated the relationship between approaches to learning…

This paper reflects upon the evolution of technology-enhanced language learning throughout the past two decades based on the author's own experience and how Information and Communications Technologies have played a prominent role on how language teaching pedagogies have evolved alongside the technologies themselves. Reference is made to the…

While some research has suggested that video lectures are just as effective as in-person lectures to convey basic information to students, not everyone agrees that the flipped classroom model is an effective way of educating students. This research explores traditional, semi-flipped and fully-flipped classroom models by comparing three sections of…

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…
