This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

This study investigated the effectiveness of videotape as a medium for communicating skills in audiovisual instruction to education students at a university. Results indicate videotape mediated instruction can be better for developing skills in some practical aspects of audiovisual instruction than the lecture method. (MBR)

Improving learning effectiveness has always been a constant challenge in software education and training. One of the primary tasks educators face is to motivate learners to perform to their best abilities. Using computer games is one means to encourage learners to learn (Klawe, 1994). When games are used in general education, they could enhance…

Introduction: Advising in Educational Psychology from the perspective of RDI takes on a stronger investigative, innovative nature. The model proposed by De la Fuente et al (2006, 2007) and Education & Psychology (2007) was applied to the field of improving teaching-learning processes at a school. Hypotheses were as follows: (1) interdependence…

The purpose of this study was to investigate the effectiveness of two death education seminars to create in the participants a better capacity to prepare for their own death and to cope with the death of others. An affective death education seminar was presented to 28 health education students, and a cognitive death education seminar was presented…

A difficulty associated with the use of Golub and Frederick's syntactic density score was the time required in hand tabulation. This drawback was resolved with the development by Kidder of a computer program which calculates a syntactic density score for writing samples. The purpose of this study was to examine the sensitivity of the Syntactic…

Develops generalizations for empirical evaluation of software based upon suitability of several research designs--pretest posttest control group, single-group pretest posttest, nonequivalent control group, time series, and regression discontinuity--to type of software being evaluated, and on circumstances under which evaluation is conducted. (MBR)

For this evaluation of a multicultural education unit, Staged Innovation Design, which allows for experimental group posttest scores to be compared to control-replication group pretest and posttest scores to ascertain instructional effectiveness, was modified by adding a simultaneous pretest for both groups to control for threats to internal…

The purpose of this study was to compare the achievement for the operations of multiplication and division on whole numbers of elementary grade students who were taught functional diagnostic strategies with a randomly selected group who were not taught the informal diagnostic strategies. Included are the methodology, results, and discussion. (KR)

The study investigated retention of gains in reading/language skills after one year by 378 eighth-grade students in 18 health studies classrooms. Six classrooms were assigned to each of three groups, two experimental and one control, taught by health science teachers who were: (1) trained in reading/language techniques; (2) not trained in…

The results of five studies of the relationship between debate training and critical thinking were examined to determine if in fact debate training improves critical thinking skills. All five studies compared the gains on the Watson-Glaser Critical Thinking Appraisal Test (WG) for subjects who had received debate training with control groups who…

Description of study to determine the impact of management training on student performance focuses on the need for proper evaluation. Pre- and posttraining evaluative tools for rating managers are described, differences in ratings are analyzed, and implications for evaluating management training on interpersonal skills are discussed. (LRW)

The insufficient educational backgrounds of secondary level science teachers and lack of student involvement in science were addressed by the implementation of a comprehensive science research program. A pretest was employed to measure the weaknesses of the science teachers at the target school. Learning strategies based upon pretest results were…

The instructional components of mediation, a teaching technique used in dynamic assessment, were evaluated with 100 four-year-old children attending daycare or preschools in London, Ontario. The effects of familiarization with task materials, task-specific rule teaching, and elaborated feedback were assessed using a pretest-posttest design.…
