Designed for use with Research for Better Schools' evaluation system, this guide focuses upon basic concepts and statistical procedures applicable to specific research hypotheses emerging from evaluation questions. The first of three sections presents a discussion of descriptive statistics in terms of frequency, central tendency, variability, and…

The ultimate goal of the institutional researcher is not always to test a research hypothesis, but more often simply to find an appropriate model to gain an understanding of the underlying characteristics and interrelationships of the data. Exploratory data analysis provides a means of accomplishing this. (Author)

This guide to program evaluation presents questions that illuminate aspects of the evaluation process. Issues to consider in program evaluation are: (1) the intended results of the program; (2) hypotheses about the possible results of the program; (3) the types of data that will indicate achievement of the intended results and the variables that…

This article explains and illustrates the estimation of the power of statistical tests used to analyze data in early childhood special education research, and discusses advantages and disadvantages of various ways to increase power, such as using a directional alternate hypothesis or using a parametric, rather than nonparametric, statistical test.…

Studies evaluating hypotheses about sources of differential item functioning (DIF) are classified into two categories: observational studies evaluating operational items and randomized DIF studies evaluating specially constructed items. For observational studies, advice is given for item classification, sample selection, the matching criterion,…

The scientific method originated centuries ago, but it is taught only to a limited degree in science classes. It is proposed that the scientific method is not just a method for scientists, but also offers a general approach to problem definition and solving and serves as a guide to problem prevention and solution-challenging. The Scientific Method…

Presents two statistical topics and examples of their use in natural resource monitoring. The first topic deals with use of correlated observations in calculations of variance estimates for a regional mean, required sample size determination, and confidence intervals. The second topic concerns the use of Bayesian techniques in hypothesis testing.…

This book provides information on what works in education, how teachers can find what works, how educational research can find its way into classrooms, and how teachers can apply it to help individual students. Data come from a meta-analysis of research studies on instructional strategies that could be used by K-12 teachers. Nine research-based…

The purpose of this notebook is to assist educators who are designing and implementing inservice education programs to facilitate the effective use of computer integrated instruction (CII) in schools. It is divided into the following five sections: (1) Effective Inservice (a brief summary of inservice literature focused on inservice dimensions and…

This report provides K-12 educators with instructional strategies that research shows have the greatest likelihood of positively affecting student learning. The 12 chapters include: (1) "Introduction"; (2) "Identifying Similarities and Differences (comparing, classifying, creating metaphors, and creating analogies); (3)…

This article discusses empowering thinking skills such as brainstorming, problem solving, analysis; comparison/contrast and how to cultivate these abilities in gifted children. Examples are given of ways for teachers to model thinking skills for students. The response of a student to the ideas of the article is included. (PB)

Develops Glaser and Strauss' (1967) suggestion that fieldwork techniques may be successfully adapted for content analysis research. Discusses relative advantages of literature and traditional fieldwork sites, and initial stages of doing fieldwork at literature sites; demonstrates method used through an evaluation of the hypothesis that prejudice…

This handbook is intended to be a self-study guide to the effective use of nine specific instructional strategies proven to improve student achievement. The strategies are: (1) identifying similarities and differences (comparing, classifying, creating metaphors, and creating analogies); (2) summarizing and note taking; (3) reinforcing effort and…

Written from the perspective of a relatively large urban school district and dealing primarily with high school-type programs, this handbook is designed for use by local school district practitioners of vocational education evaluation.
