This research aims to investigate the construction of the area of rectangle with GeoGebra and how students can formulate it. It focuses on describing the cognitive process involved in constructing this concept and how technology mediates such a process. The research was conducted in a classroom with 5th grade students in a secondary school and was…

The paper addresses concept formation processes of students in the field of geometry. More precisely, the paper deals with the questions of what knowledge do students activate about triangles in different contexts with different (digital) tools and furthermore what content-related meaning do they give to the concept of triangles? Methodologically,…

This article presents an analysis of students' conceptual understanding of technology. The study focused on two groups of seventh-grade students located in Bogotá, Colombia, living in rural and urban areas and participating in activities developed in a virtual learning network. The methods used in this study followed grounded theory (Strauss &…

We present here the lessons learned by iteratively designing a tutorial for first-year university students using computer programming to work with mathematical models. Alternating between design and implementation, we used video-taped task interviews and classroom observations to ensure that the design promoted student understanding. The final…

Background and purpose: To date, there has been little research on the Teacher Professional Development (TPD) for delivering a mobile technology-supported science curriculum. To address this, a TPD model for a science curriculum supported by mobile technology was developed and evaluated in this paper. The study reported focuses on the…

This paper describes the use of activity theory to compare dissimilar cases in a study of adult online music learners. The purpose of the study was to better understand the barriers that keep self-motivated users of online open education resources from experiencing successful independent learning. Eleven participants were given tutoring-style help…

Educational technologies develop quickly. Which functions of face-to-face education can be substituted by technology for distance learning? One of the risks of online education is the lack of embodied interactions. We investigate what embodied interactive technologies might offer for teaching trigonometry when learning at a distance. In a multiple…

In this article, the author shares the results of a case study that explored how using student-produced video essays supported historical thinking. The goal of this study was to explore the intersection of historical literacies in relationship with digital practices and see how digital literacies might be used to engage students' historical…

Despite significant research exploring students' quantitative reasoning, few studies have explored the semiotic processes that mediate its development. In this report, we present a case study to show how one student constructed a semiotic chain for a quantity as he worked with a mathematical task. Importantly, we connect frameworks for…

This study draws on four case studies of young children in order to explore the relationship between children's action schema [Athey, C. (1990). "Extending though in young children: A parent-teacher partnership." London: Paul Chapman] and their developing speech, language and communication. What emerged was a connection through…

Background: Constructing knowledge through collaborative practical work is a complex process and involves the use of multiple modalities by group members. In practical work sessions, students often manipulate visual objects or textual materials but do not develop their scientific ideas. Purpose: This study illustrates (a) the challenges that…

Adaptive teaching on the micro-level of teacher-student interaction has often been investigated, but rarely with respect to students' content-specific learning pathways. In this paper, we present an analytic approach to disentangle the learning content into its components and to capture the content-specific adaptivity in teaching practices with…

Teacher professional learning occurs across various contexts. Previous studies on teacher learning and changes in practice have focused on either classroom contexts or learning communities outside of school, but have rarely investigated teacher learning across multiple contexts. Investigating teacher learning across the double contexts of…

The purpose of this study is to discover pre-school children's vocabulary learning, retention levels, and perspectives of English language learning using augmented reality (AR) technology. To achieve this goal, a one-group pre-test, and post-test design was used to assess the effect of using AR-supported educational toys on pre-school children's…

The purpose of this research was to study the system of resources, the objectives of their use and the factors that affect the selection and integration of the different resources by Lebanese secondary physics teachers in their teaching in general and for teaching Electricity in particular. For this aim, a qualitative approach was used and the…
