Effects on cognitive performance, social atmosphere, communication, motivation and aspects of strain were investigated when laptops were integrated in classrooms. According to a quasi-experimental design 27 laptop students were compared with 22 non-laptop students from the same high school, aged 17-18 years. Results of tests and questionnaires showed that laptop students had better spatial abilities and computer skills, furthermore higher participation, learning interest, motivation and pressure to perform were found in laptop classrooms. However, laptop students experienced greater physical discomfort, particularly in their arms, but concerning creativity, social intelligence and mental stress no group differences occurred. Results indicate that laptops integrated in teaching can enhance learning and motivation in schools, at least after 1.7 years of introduction, but health risks must be considered.
Psychometric evaluations in laptop classroomsIn a time characterized by rapid technological developments, our society is becoming increasingly more dependent on information technology, and particularly on computers. As a result the effective use of computers and computer applications becomes an essential requirement in a modern society. It is assumed that computer implementation in education will foster not only the acquisition of cross curricular and media competencies but also of team and cooperation skills as well as of meaningful learning in complex and authentic environments. In the recent international debate about the necessity of innovated classroom instruction mobile computers, such as laptops, are seen as especially beneficial to initiate lasting changes in the nature of learning and teaching. Over the past decade the presence of computers in schools has exploded and laptops have become a daily learning and working tool for many students all over the world. At the beginning laptop programs were not attended by systematic research studies. Not until the last few years, longitudinal studies in the area of educational computering took place. Most of the existing evaluations are based on written and oral surveys, just in particular cases, observations and standardized achievement tests to measure changes concerning performance in certain school subjects were used. Several studies suggest educational benefits related to laptop use, others reported inconsistent results. Schaumburg (2001) gives an overview of recent empirical findings of international evaluation studies, which are mostly focusing on changes in student learning, instructional practices, student achievement and cross-curricular competencies. The wide range of recent studies can be summarized under the following four areas: effects on cognitive, social and Correspondence: M. Trimmel,
