The purpose of this note is to introduce two challenging problems in geometry that were inspired by some well-known problems in high school geometry. These problems can be explored in the dynamic geometry environments of computer construction programmes.

In this study, the contribution of the 3D computer modeling to the twenty-first century's common competencies was evaluated from the perspective of secondary school students. The one-group post-test only design was used in the study. The instruments of the data collection process were an achievement test and a questionnaire developed by the…

E-learning anxiety plays a key role in students' success in online courses. One of the factors that may affect students' e-learning anxiety is computer self-efficacy (CSE). However, the role of CSE in high school students' e-learning anxiety has remained unexplored in the Iranian context. Therefore, the present mixed-methods study purports to…

The article presents some examples of plane geometric variance of an area with the use of computer technology. These tools can offer teachers opportunities for adaptation and preparation of pedagogical presentations which will help students along the process of fruitful conjectures formation and eventually construction of formal deductive proofs.…

A Multi-touch table functions as a tablet, but allows multiple children to move around and manipulate the screen simultaneously. Using social cognitive theory (Bandura 1997) to analyze group dynamics, this study examined computer-supported collaborative learning. Children were observed and recorded for 20 min, three times a week for 5 weeks as…

These proceedings contain the papers of the 21st International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2024), held in Zagreb, Croatia, from 26 to 28 October 2024 and organized by the International Association for Development of the Information Society (IADIS). The CELDA conference aims to address the main issues…

This research aims to explore the latent effect of elementary student engagement in a Spherical Video-based Virtual Reality (SVVR) environment for a school-based course on higher level competence development. Student engagement and higher level competence development were investigated using a valid sample of 324 students from five elementary…

Self-assessment, in the education framework, is a methodology that motivates students to play an active role in reviewing their performance. It is defined as "the evaluation or judgment of 'the worth' of one's performance and the identification of one's strengths and weaknesses with a view to improving one's learning outcomes". The goal…

This brief provides considerations for conducting and implementing functional behavior assessments (FBA) and behavior intervention plans (BIPs) using virtual technology. There are many situations in which virtual FBA/BIP implementation may be necessary or desired. For example, virtual FBA/BIPs can support students attending schools in areas that…

Connecting theory and practice in teaching is sometimes difficult, as it requires expensive or delicate equipment, thus limiting the teacher to giving demonstrations in which students are passive participants. Numerical mathematics, as an applied discipline, should be taught on real world examples. By using inexpensive Arduino hardware, we can…

This case study used a design-based research approach to examine the development and evaluation of an online homework system to support learning and problem-solving in a high school physics course. Emergent themes included challenges of building the system, strengths and weaknesses of it, and the benefits to students. While the system largely met…

This paper describes a high school or introductory university course in scientific programming that introduces the computer revolution into the physics curriculum at the beginning. In the first one-hour lecture, Euler's method is presented and used to compute a solution to the analytically unsolvable two-body problem. In the remainder of the…

Many engineering subjects rely on the interpretation of symbolic, numeric and graphic representations. Engineering students have challenges pertaining to their mathematical understanding of their actions with a computer algebra system (CAS). We investigated how a mathematical modelling task could mediate varied levels of mathematical…

The scale-invariant way to analyze two-dimensional experimental and theoretical data with statistical errors in both the independent and dependent variables is revisited by using what we call the triangular linear regression method. This is compared to the standard least-squares fit approach by applying it to typical simple sets of example data…

The perspective that computing and computational thinking (CT) are necessary competencies for the 21st century is increasingly pervasive. Computational concepts and methods--problem solving, designing systems, refining the steps in a process, and tinkering toward creative solutions--are relevant in nearly every discipline, profession, and…
