Learning a more distributed representation of the input feature space is a powerful method to boost the performance of a given predictor. Often this is accomplished by partitioning the data into homogeneous groups by clustering so that separate models could be trained on each cluster. Intuitively each such predictor is a better representative of…

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a…

Creative problem-finding ability (CPFA) is an important component of creativity, but research into it has just started and results so far could not offer much guidance to teaching. This study utilized a 2 (teaching materials or tasks of different difficulty: high and low) × 3 (group member construction: homogeneous group, heterogeneous group, and…

The present study aimed at finding the effectiveness of the Laboratory Training Model of Teaching (LTM) and comparing it with the traditional methods of teaching chemistry to seventh standard students. It strived to determine whether the (LTM) method in chemistry would be significantly more effective than the Traditional method in respect to the…

Noting that lack of student motivation is one of the primary reasons students drop out of school and that lack of student motivation is particularly evident at the onset of adolescence, this study compared multidimensional motivation gains of middle school students who were heterogeneously grouped according to motivational level to gains of those…

Describes study that compared the achievement of high and low ability eighth-grade students working cooperatively during computer-based instruction. Homogeneous and heterogeneous grouping based on ability are explained, posttest results are analyzed, and implications for instructional design are discussed. (23 references) (Author/LRW)

Recent work in small-group computer-based training (CBT) reveals that the approach does not necessarily lead to higher achievement. Many of the studies, however, have methodological weaknesses. If proper guidance and structure can be provided to group members, using small group CBT should lead to higher achievement than individual CBT. (Contains…

This study examined the effects of instructional control and aptitude composition on performance, interaction, and attitudes during a computer-based cooperative science lesson. A sample of 152 fifth and sixth grade students completed the instruction either under the learner control (LC) or the program control (PC) treatment. In the LC treatment,…
