The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

This study evaluated the feasibility and outcomes of a parent-implemented phonological awareness (PA) intervention for young children with specific language impairment. The intervention was delivered within the context of 40 parent-child shared storybook reading sessions conducted over a 10-week period in the families' homes. Children in an…

This study investigated whether the software Virtus WalkThrough Pro could be used to enhance middle school children's spatial ability as measured by the Paper Folding, Mental Rotations, and Eliot-Price Tests. The study also investigated whether the use of this software impacted males differently than females, or users with high spatial ability…

A sample of 490 high school students from 81 schools in Michigan participated in an experiment in which they were randomly assigned to either a control or an experimental Web site. The experimental Web site provided exposure to educational material about the process of organ donation and organ transplantation. The control Web site provided…

Internet is the most important technological innovation of today, which can easily be integrated into every field of people's lives. The reason of its rapid improvement is its usefulness and easy access. Web, WWW, is a new technology which is used as a communication facilitator and it is an instructional delivery medium. It is vital to learn…

This research compared the effects of a Programmed Learning Sequence (PLS) (Dunn & Dunn, 1993) versus Traditional Teaching (TT) on 100 sixth-grade Bermudian students' test scores on a Fractions Unit. Fifty-three males' and forty-seven females' learning styles were identified with the "Learning Style Inventory" (LSI) (Dunn, Dunn,…

The purpose of this study was to determine the effectiveness of visual perceptual training on word recognition and reading achievement of disadvantaged first grade pupils. The experimental groups received the Frostig Program for the Development of Visual Perception in addition to the regular readiness program for a period of 12 weeks. The control…

A pretest-posttest control group design was used to assess the leadership and problem-solving skills of 281 participants and 110 controls in a statewide community leadership development program. Quantitative and qualitative data demonstrate that the program has been a catalyst to influence leadership and problem-solving skills for community…

Already at a very young age, children experience the wide applicability and intrinsic simplicity of linear/proportional relations. In primary and secondary school mathematics education, moreover, extensive attention is paid to this type of relations. In the long run, students develop the misbelief that each relation can be quantified as…

Contrary to conventional expectations, the reality of computing education in Taiwan's vocational schools is not so practically oriented, and thus reveals much room for improvement. In this context, we conducted a quasi-experiment to examine the effects of applying web-based problem-based learning (PBL), web-based self-regulated learning (SRL), and…

This research project consists of a randomized experiment in a few of the Reynoldsburg City Schools. The primary purpose of this research is to produce scientifically based evidence of the comparative effectiveness of the "Scott Foresman Science" ("SFScience)" program. The question being addressed by the research is whether…

Singing exaggerates the language of reading. The students find their voices in the rhythm and bounce of language by using music as an alternative technological approach to reading. A concurrent mixed methods study was conducted to investigate the use of an interactive sing-to-read program Tune Into Reading (Electronic Learning Products, 2006)…

This report summarizes the activities and findings of the external evaluation of the "Science: It's Elementary" (SIE) program in the period June 2007 through May 2008. The SIE program is managed by ASSET Inc. and overseen by the Pennsylvania Department of Education. SIE is an initiative aimed at improving elementary science instruction…

Two groups of middle school students were taught U.S. colonial history during a 5-week period using 2 different instructional strategies. In the experimental group, concepts and problem-solving strategies were explicitly taught; in the control group, content was presented using lectures and reading. All students took a pretest and several…

This study investigated differences in achievement for control groups learning college algebra using traditional classroom instruction methods compared to experimental groups using computer algebra tutorials for three precalculus topics. Two instructors each taught one control group and one experimental group. No significant differences were…
