Hwang, Wu-Yuin; Hu, Shih-Shin – Computers & Education, 2013
Learning geometry emphasizes the importance of exploring different representations such as virtual manipulatives, written math formulas, and verbal explanations, which help students build math concepts and develop critical thinking. Besides helping individuals construct math knowledge, peer interaction also plays a crucial role in promoting an…

Barbalios, N.; Ioannidou, I.; Tzionas, P.; Paraskeuopoulos, S. – Computers & Education, 2013
This paper introduces a realistic 3D model supported virtual environment for environmental education, that highlights the importance of water resource sharing by focusing on the tragedy of the commons dilemma. The proposed virtual environment entails simulations that are controlled by a multi-agent simulation model of a real ecosystem consisting…

Bouyias, Yannis; Demetriadis, Stavros – Computers & Education, 2012
Research on computer-supported collaborative learning (CSCL) has strongly emphasized the value of providing student support with micro-scripts, which should withdraw (fade-out) allowing students to practice the acquired skills. However, research on fading shows conflicting results and some researchers suggest that the impact of fading is enhanced…

Tomai, Manuela; Rosa, Veronica; Mebane, Minou Ella; D'Acunti, Alessia; Benedetti, Maura; Francescato, Donata – Computers & Education, 2010
The general aim of this study was to test the hypothesis that students belonging to a school online community would show higher levels of both offline bridging and bonding social capital than a control group of students, not using the online community. We further hypothesized that the more students used the online community the higher their level…

Grubisic, Ani; Stankov, Slavomir; Rosic, Marko; Zitko, Branko – Computers & Education, 2009
We believe that every effectiveness evaluation should be replicated at least in order to verify the original results and to indicate evaluated e-learning system's advantages or disadvantages. This paper presents the methodology for conducting controlled experiment replication, as well as, results of a controlled experiment and an internal…

Kose, Erdogan – Computers & Education, 2009
The objective of this study is to assess the effectiveness of the educational environment supported by computer aided presentations at primary school. The effectiveness of the environment has been evaluated in terms of students' learning and remembering what they have learnt. In the study, we have compared experimental group and control group in…
