GeoGebraBook is a pedagogical resource in the form of a digital book created and developed for free on the GeoGebra online page. This paper presents preliminary research using GeoGebraBook to support explaining the area of a flat figure and the volume of a solid. The study was based on qualitative and quantitative research and involved forty-four…

This study was conducted to determine whether there were significant differences between students' reasoning abilities taught using the PBL model and with the Computer Multimedia Assisted GI, and to determine whether or not there was an influence of interaction between learning models and students' initial abilities on mathematical reasoning…

Science educators increasingly call for students to address authentic scientific problems in science class. One form of authentic science problem--socioscientific issue--requires that students engage in complex reasoning by considering both scientific and social implications of problems. Computer-based scaffolding can support this process by…

Educational affordances are worthy of being explored because the affordances of Information and Communication Technologies (ICT) provide the pedagogical effects for promoting cognitive acceleration, increasing the self-management of students, facilitating data collection, and presentation in science learning. This study aims to explore educational…

Hypothesis development is a complex cognitive activity, but one that is critical as a means of reducing uncertainty during ill-structured problem solving. In this study, we examined the effect of metacognitive scaffolds in strengthening hypothesis development. We also examined the influence of hypothesis development on young adolescents'…

This study developed a computer-assisted mathematical problem-solving system in the form of a network instruction website to help low-achieving second- and third-graders in mathematics with word-based addition and subtraction questions in Taiwan. According to Polya's problem-solving model, the system is designed to guide these low-achievers…

Two grade 5 classes (11-12-year-olds) were introduced through an inquiry-based pedagogy to scientific ideas and concepts within a 3D game-like multi-user virtual environment (MUVE). This article explores how a particular set of strategies and conditions might encourage and sustain the use of the MUVE, Quest Atlantis (QA), as a problem-based…

Teachers' implementation of a problem-based learning (PBL) program was examined to determine both how they assessed student learning and their reasons for these assessment practices. Ten 6th grade science teachers used Alien Rescue, a computer-based PBL module, with their students for approximately three weeks. Interviews, observations, and…

This study implemented a three-stage problem-based estimation instruction scenario and combined it with mobile technology to provide elementary teachers with an effective e-tool for observing student estimation and leading effective class or group discussions on the selection and assessment of appropriate strategies for solving daily estimation…

The momentum gathering behind authentic learning/critical skills raises fundamental issues concerning teaching and learning. This article discusses some of the more general arguments surrounding authentic learning with particular reference to an in-depth evaluation of its impact on schools in one part of Great Britain. It then moves on to describe…
