This study examined the effect of cognitive demand on situational interest and performance using running tasks in physical education. Adolescents (N = 179) participated in a field study involving three different levels of cognitive demand. Running performances and situational interest were measured four times with a testing interval of seven days.…

Field experiments in education frequently assign entire groups such as schools to treatment or control conditions. These experiments incorporate sometimes a longitudinal component where for example students are followed over time to assess differences in the average rate of linear change, or rate of acceleration. In this study, we provide methods…

Our study investigated whether problem-oriented designed ecology lessons with phases of direct instruction and of open experimentation foster the development of cross-domain and domain-specific components of "experimental problem-solving ability" better than conventional lessons in science. We used a paper-and-pencil test to assess…

This paper provides a guide to calculating statistical power for the complex multilevel designs that are used in most field studies in education research. For multilevel evaluation studies in the field of education, it is important to account for the impact of clustering on the standard errors of estimates of treatment effects. Using ideas from…

Field tests on an interpersonal skills instructional program, the Heartsmart Adventures, were conducted for the formative and summative evaluation in 14 classrooms in 7 schools of 394 students in grade 4 classes. The results indicate that the Heartsmart program is likely to provide an appealing, educationally relevant and worthwhile experience to…

Discusses the use of multimedia to facilitate learning processes; reviews research that addresses specific effects of media; and describes studies of high school students that tested the influence of video, photography, and individualized testing on acceptance and recall of information provided by a multimedia encyclopedia about professions and…
