Ray tracing is a computer graphics technique used to produce realistic visuals by physically simulating the behavior of light. Although this technique can be described straightforwardly, fully comprehending it might be challenging. It is typically taught in the classroom using the 2-D formats, such as paper or a blackboard. We propose using…

The problem that the research is aimed at is caused by the need to resolve the contradiction between the public demand for the quality of training the future digital school teacher regarding the formation of information culture, creativity, communication skills, the ability to work in a team, readiness for change, and the insufficiently developed…

Computational Thinking (CT) has been formally incorporated into the National Curriculum of Thailand since 2017, where Scratch, a block-based visual programming language, has been widely adopted as CT learning environment for primary-level students. However, conducting hands-on coding activities in a classroom has caused substantial challenges…

In this paper, we describe a code-reading support environment and practical classroom applications using this environment to understand nested loops. Previously, we developed a code-reading support system based on visualization of the relationships among the program code, target domain world, and operations. We implemented the proposed system in…

Polar research plays a vital role in developing our understanding of Earth's climate system. It is intrinsically interdisciplinary, lending itself to integration into existing undergraduate courses. Here we explore introducing undergraduates to polar research through computational guided inquiry (CGI) modules taught in a variety of courses and…

The results presented in this paper contribute to research on two different areas of teaching methods: distributed pair programming (DPP) and computer-supported collaborative learning (CSCL). An evaluation study of a DPP system that supports collaboration scripts was conducted over one semester of a computer science course. Seventy-four students…

Learning the syntax, semantics, and concepts behind software engineering can be a challenging task for many individuals. This paper examines the Alice 3 software, a three-dimensional visual environment for teaching programming concepts, to determine if it is an effective tool for improving student achievement, raising self-efficacy, and engaging…

We present CSTutor, a sketch-based interface designed to help students understand data structures, specifically Linked Lists, Binary Search Trees, AVL Trees, and Heaps. CSTutor creates an environment that seamlessly combines a user's sketched diagram and code. In each of these data structure modes, the user can naturally sketch a data structure on…

Greedy algorithms constitute an apparently simple algorithm design technique, but its learning goals are not simple to achieve.We present a didacticmethod aimed at promoting active learning of greedy algorithms. The method is focused on the concept of selection function, and is based on explicit learning goals. It mainly consists of an…

Several years ago we presented an experimental, discovery-learning approach to the active learning of greedy algorithms. This paper presents GreedEx, a visualization tool developed to support this didactic method. The paper states the design goals of GreedEx, makes explicit the major design decisions adopted, and describes its main characteristics…

Having implemented and evaluated over 35 mlearning projects in a variety of contexts in higher education over the past 6 years the researcher is ready to share the untold secret: not all mlearning projects succeed! This article critiques three of the researcher's mlearning projects that can be classed as "failures" and compares them to successful…

Peer evaluations are often used to improve learning in educational settings. As more and more online courses are offered, it is becoming increasingly important to explore new techniques for conducting peer evaluation in online courses. In recent years, wikis have increasingly been used in higher education to support learning and group work.…

Skill shortages in the area of computer network troubleshooting are becoming increasingly acute. According to research sponsored by Cisco's Learning Institute, the demand for professionals with computer networking skills in the United States and Canada will outpace the supply of workers with those skills by an average of eight percent per year…

This research explored the influence of a Web-based portfolio assessment system on students' performances. The methodological procedure adopted was to have the experimental group use the system, with the control group using conventional assessment. The study subjects were junior high school students of two computer classes. The experimental…

Among educational researchers and practitioners, there is a growing interest in employing computer games for pedagogical purposes. The present research integrated a technology education class and a science class where 5th graders learned about environmental issues by designing games that involved environmental concepts. The purposes of this study…
