Purpose: A growing trend in instructional improvement efforts is the use of formative assessment informed by research-based developmental trajectories of how students gain deeper understanding of subject matter content over time. This article reports the findings of a large-scale experimental study of an innovative mathematics professional…

In 2011, Indiana lawmakers established a system to evaluate teachers using existing standardized assessments as an indicator of student learning. In this study we examined one component of Indiana's evaluation system to determine whether student knowledge of the test's consequences is predictive of test performance. Using an experimental design,…

This teaching experiment provided students with continuous engagement in a problem-solving based instructional approach during one mathematics unit. Three sections of sixth-grade mathematics were sampled from a school in Florida, U.S.A. and one section was randomly assigned to experience teaching through problem solving. Students' problem-solving…

This article examines an educational experiment with a unique combination of 3 elements: homework, the use of information and communication technology and a large degree of freedom of choice (student autonomy). More particularly, we study the effectiveness of a web-based intelligent tutoring system (ITS) that a school offers to its students as…

Today's students are disengaged, disenfranchised, and dropping out in record numbers. If this trend continues, educators and academic institutions everywhere are in jeopardy of exacerbating the wide chasm that separates students from learning. This was a quasi-experimental, causal-comparative, action-research study. The researcher implemented…

This experiment illustrates how the effective use of a technology treatment integrated into pre-algebra curricula can help students achieve on the New Jersey Standardized Grade 8 Proficiency Assessment (GEPA). The researcher obtained data by comparing a treatment group to a control group; the first group was given a weekly 44-minute-long…

This paper provides a guide to the minimum size of treatment groups, inferred from the relationships between pupil norms and norms for class averages of standardized achievement tests. (Editor)

This report describes briefly the experimental design and presents the basic contract provisions. The experiment results reveal that performance contracting is no more successful than traditional classroom methods in improving the reading and mathematics skills of poor children. Both control and experimental groups performed equally poorly in…

The performance of two groups of adult students on the General Educational Development (GED) test was compared to determine whether there was a relationship between the level of student performance on a timed versus non-timed GED test. Each group consisted of the first three hundred students who took the test at twenty-six different testing…

This report describes the experimental design, presents the contract provisions, and provides conclusions and recommendations. The document is comprised of five chapters that discuss (1) the statistical analysis methods used, (2) the problems of using standardized tests in performance contracting, (3) the contractual procedures between OEO and the…

This report represents an integration of analysis results in an interim report with those from additional analyses performed since. It is divided into (1) description of the experiment in which the goal is outlined; (2) description of the technology company programs, an overview of personnel, curriculum and materials, and incentive systems; (3)…

An experiment, using College Board Achievement Tests in German Reading and Listening Comprehension, to compare the effectiveness of earphones and loudspeakers in language test presentation is described. Related opinions, implications, and conclusions on the effectiveness of communication media in language teaching and testing are offered. (AF)

This study reviews current research seeking to determine the relative importance of methodology upon success in language learning programs. Six language classes, instructed for a full academic year according to either the principles of the audiolingual or cognitive code language learning theory, were the focus of an experiment to statistically…

This report describes an experiment concerned with a possible relationship between the inability to learn basic educational skills, such as reading and writing, and the inability to organize incoming stimuli for communication purposes, in spite of adequate intellectual potential. The study had three main tasks. The first problem was to develop a…

Three models of educational evaluation are discussed: the intuitive decisions model, the experimental model, and the feedback model. The feedback model is most useful because it will provide baseline information about current accomplishments of the school systems. Once the feedback process is well underway, it is then profitable to discuss goals.…
