The main objective of this study was to evaluate the effects of the introduction of educational videogames into the classroom, on learning, motivation, and classroom dynamics. These effects were studied using a sample of 1274 students from economically disadvantaged schools in Chile. The videogames were specifically designed to address the educational goals of the first and second years of school, for basic mathematics and reading comprehension. The sample was divided into experimental groups (EG), internal control groups (IC) and external control groups (EC). Students in the EG groups, used the experimental video games during an average of 30 h over a 3-month period. They were evaluated on their acquisition of reading comprehension, spelling, and mathematical skills, and on their motivation to use video games. Teachers' expectations of change due to the use of video games, their technological transfer, and handling of classroom dynamics, were assessed through ad hoc tests and classroom observations. The results show significant differences between the EG and IC groups in relation to the EC group in Math, Reading Comprehension and Spelling, but no significant differences in these aspects were found between the EG and the IC groups. Teacher reports and classroom observations confirm an improvement in motivation to learn, and a positive technological transfer of the experimental tool. Although further studies regarding the effects of learning through videogame use are imperative, positive effects on motivation and classroom dynamics, indicate that the introduction of educational video games can be a useful tool in promoting learning within the classroom. #

This paper sets out to address the problem of the imbalance between the number of quantitative and qualitative articles published in highly ranked research journals, by providing guidelines for the design, implementation and reporting of qualitative research. Clarification is provided of key terms (such as quantitative and qualitative) and the interrelationships between them. The relative risks and benefits of using guidelines for qualitative research are considered, and the importance of using any such guidelines flexibly is highlighted. The proposed guidelines are based on a synthesis of existing guidelines and syntheses of guidelines from a range of fields.

There is a need to incorporate constructivist environments in the pedagogical practice. A constructivist learning environment allows students to build up their own knowledge (based on previous one) while working jointly among them in a reflexive process directed by the teacher. Wireless interconnected handhelds can introduce a space that favours constructivism and collaboration in order to achieve creation of new knowledge. We have developed a constructivist learning environment supported by handhelds, for the teaching of reading for first graders. This environment was compared to an equivalent constructivist environment without technological support, obtaining significant different learning results.

There is a need for collaborative group activities that promote student social interaction in the classroom. Handheld computers interconnected by a wireless network allow people who work on a common task to interact face to face while maintaining the mediation afforded by a technology-based system. Wirelessly interconnected handhelds open up new opportunities for introducing collaboration and thereby changing classroom pedagogical practices. We present a conceptual framework and a method for the design of a mobile computer-supported collaborative learning system based on Activity Theory. An instance of the framework for teaching basic mathematics skills was evaluated with 24 6- and 7-year-old children in a month-long study. Positive effects were observed on student social interaction, motivation and learning.This paper was partially funded by Fondecyt 1050601
