Action research often necessitates the use of intact groups for the comparison of educational treatments or programs. This paper considers several analytical methods that might be used for such situations when pretest scores indicate that these intact groups differ significantly initially. The methods considered include gain score analysis of…

The norm-referenced evaluation model (RMC Model A) for Title I project evaluation, consists of procedures whereby the expected posttest standing of a treatment group under the null condition is generated from their pretest standing. It is assumed that the treatment group is not selected on the basis of their pretest scores and can be considered…

In the second year of a study to compare and evaluate programed and conventional instruction in algebra for the ninth and tenth grades, comparisons of the control and experimental groups in each grade were again based on scores from the Lankton First-Year Algebra Test and the California Study Methods Survey (CSMS). Although there was a…

Ninth and tenth grade students from two schools were placed in experimental and conventional instruction classes to compare the two methods in teaching algebra by means of achievement test and time needed to complete the course. Pre- and posttests measured aptitude; teachers and students in the experimental groups recorded personal reactions to…

This volume is the technical appendixes to the evaluation study (ED 142 795) of the Career Intern Program (CIP), a program effort to help urban youth get a basic education and further training or a paying job. These appendixes include descriptions of the evaluation design, study sample, statistical treatment of the data, and measures used,…

With an increase concern for childhood obesity, many individuals and organizations are emphasizing the importance of quality physical education. The need for quality physical education at the elementary level is extremely important as research has shown a relationship between the performance of fundamental movement skills and children's body…

This study reports on the impact of a 2-month classroom intervention that sought to alter the learning environment of two Hong Kong Primary Year 3 general studies classrooms. Mixed methodology, employing quantitative and qualitative data-gathering strategies, was used to investigate changes to the learning environments, including changes to the…

The measurement of change is such a broad topic that this article must limit its focus to a few specific subtopics. These specific topics include: longitudinal research design, attrition in research studies, the statistical analysis of difference scores, and the comparison of analysis of variance (ANOVA) and multivariate analysis of variance…

A case study of a child who was a part of a larger reading-practice research study is presented. Data analysis from the larger study yielded a strong effect size for children in the experimental group who used decodable text for reading practice. The pre- and posttest scores of one child included in the treatment were not used in the statistical…

The purpose of this study was to explore the effectiveness of using ALEKS (Assessment and Learning in Knowledge Spaces [3]), an online interactive learning system, in teaching a college algebra course at a university. This system was used to replace traditional assignments. The study was conducted in eight college algebra courses in the Fall 2003…

Efforts to improve the educational achievement of children, especially those from disadvantaged backgrounds, are at the heart of current government policies in the United Kingdom. The Peers Early Education Partnership (PEEP) is an intervention that, since 1995, has worked directly with parents and caregivers of children from infancy to 5 years of…

The purpose of this study was to compare traditional classification training for a set of abstract concepts with multiple-relations training consisting of inference practice and the use of a content diagram. To examine this, 200 undergraduate and graduate psychology students completed a Web-based tutorial covering the abstract concepts of a…

This study examined the impact of Computer Assisted Language Learning (CALL) on Korean TAFE (Technical and Further Education) college students in an English as a Foreign Language (EFL) reading classroom in terms of their perceptions of learning environment and their reading performance. The study compared CALL and traditional reading classes over…

This paper reports findings of a study that examined student performance and attitudes towards the use of information technology in virtual and conventional settings. Students were preservice undergraduate and graduate students enrolled in an educational media and technology course. All were fulltime, on-campus students, but one group completed…

This investigation compares and analyses the experiences and subjective cognitive workload of students undertaking a lesson on an aspect of micro-level writing skills in a web-based and paperbased version. Both versions of the lesson were based on the principles of interactive learning, specifically on a modified version of Chou's (2003) model.…
