The purpose of this study was to investigate the effectiveness of cognitive conflict based physics instruction over traditionally designed physics instruction on preservice primary school teachers at grade 2. The subjects were 82 (27 boys, 55 girls) second grade pre-service teachers in two classes. One of the classes (42 students) was randomly…

This study attempts to determine whether there exists a negative interconnection between the creative and testable nature-of-science (NOS) conceptions in college students' conceptual ecology by investigating, through a pair of IHV-assisted teaching experiments, the effect of raising the status of each NOS conception in students' conceptual ecology…

To eliminate maturation as a factor in the pretest-posttest design, pretest scores can be converted to anticipate posttest scores using grade equivalent scores from standardized tests. This conversion, known as historical regression, assumes that without specific intervention, growth will continue at the rate (grade equivalents per year of…

Two types of sensitivity indices were developed in this paper, one internal to the total test and the second external. To evaluate the success of these statistics the three criteria suggested for a satisfactory index of item quality were considered. The Internal Sensitivity Index appears to meet these demands. Certainly it is easily computed. In…

The major purpose of this study was to ascertain the relative effects of student exposure to instructional objectives upon student self-evaluation of psychomotor activities in a college-level power mechanics course. A randomized posttest-only control group design was used with two different approaches to the statement of the objectives. Four…

Five methods for analyzing data from pretest-post-test research designs are discussed. Analysis of gain scores, with pretests as a covariate, is indicated as a superior method when the assumptions underlying covariance analysis are met. (Author/GDC)

This article presents a guide that seeks to provide assistance to educational practitioners in evaluating whether an educational intervention is backed by rigorous evidence of effectiveness, and in implementing evidence-based interventions in their schools or classrooms. The guide is organized in four parts: (1) A description of the randomized…

This study assesses the results of a 2-year community-based peer education program aimed at increasing HIV/AIDS knowledge, attitudes toward condoms, and condom use behavior among taxicab and tricycle drivers in the Philippines. Pretest, posttest, and follow-up data were collected throughout the educational intervention program. The results of the…

Modular technology education (MTE) has grown considerably since the middle of the 1980s. MTE is defined as a curriculum provided by a commercial vendor in which students learn about an area of technology by: (1) participating in interactive media presentations; (2) following instructions in workbooks; (3) writing responses in student journals; and…

Most of us want our students to feel that mathematics is an enjoyable and rewarding study for them … but do we succeed? Some of our students are successful whereas others are anxious and fearful. The performance of Malaysian students in mathematics has been generally been not good. It has been realized that poor mathematics performance of students…

Mathematical knowledge and understanding is important not only for scientific progress and development but also for its day-to-day application in social sciences and arts, government, business and management studies and household chores. But the general performance in school mathematics in Kenya has been poor over the years. There is evidence that…

Following the exponential increase in the global usage of the Internet as one of the main tools for communication, the Internet established itself as the fourth most powerful media. In a similar vein, computer literacy education and related courses established themselves as the essential components of the Faculty of Communication and Media…

Describes study designed to determine whether seventh-grade students classified as field dependent or independent would respond to computer assisted instructional options in different ways. Chi-square analysis reveals both groups showed similar pattern options use except in the case of additional expository examples where field-dependent students…

Describes the Biomechanics Tutorial, a computer-aided instructional tool that was developed at Ohio State University to expedite the transition from lecture to application for undergraduate students. Reports evaluation results that used statistical analyses and student questionnaires to show improved performance on posttests as well as positive…

This study was an investigation of the effects of sequenced Kodaly literacy-based music instruction on the spatial reasoning skills of kindergarten students. Subjects in the pretest-posttest control group design were 54 kindergarten students who were enrolled in three kindergarten classes in a rural elementary community school. Experimental group…
