An analysis of various studies which have examined the effect of questions in the textual content of instructional materials. (JB)

There is evidence that pre-tests can have orienting and motivational and teaching functions - in addition to the sought-for testing function. There is also evidence that these additional functions can be either general or specific. The present paper contributes to the ongoing debate by discussing the issues involved in the context of a series of…

To evaluate changes of attitude by vocational educators during a summer workshop in educational research, statistical data was obtained from a sample of four school administrators and 12 vocational education teachers who attended the workshop. Chi-square analysis and a Z test were utilized in evaluating attitude changes based on a pre- and a…

Supported by this experimental study was the hypothesis that science process skills of premedical and predental students could be improved by a semester-long course modeled after the AAAS Science - A Process Approach curriculum. Recommendations are made regarding the inclusion of science process skills in college science courses. (CS)

The measurement of change in quasi-experimental educational research was discussed. Problems related to measuring change exist to varying degrees in all research designs; these issues are less troublesome in experimental studies because the investigator can manipulate the interest variables and observe their effects on other variables. Measuring…

The evaluation design, which prescribes when and from whom to gather data, is described as significant because it can lend credibility to evaluation results. The objectives of this booklet are to aid the evaluator in: choosing a design; putting it into operation; and analyzing and reporting the data. Examples include both formative and summative…

An overall analysis is made of the impact of Grade 3 Title I reading programs in the State of Michigan. An attempt is made to estimate the effectiveness of particular reading programs for low-scoring, middle-scoring, and high-scoring pupils for the purpose of identifying exemplary programs. In addition, a rank ordering of the various programs…

The World of Manufacturing is an Industrial Arts Curriculum Project designed to acquaint junior high school students with all the major phases of the manufacturing industry. This publication reports the evaluation of a World of Manufacturing program implemented into the Pontiac School District during the 1970-1971 school year. During the summer of…

The major purposes of this study were to develop a process for the application of a "judgemental procedure" to program construction in vocational and practical arts education, and to apply the process in a selected local community. The "judgemental procedure" was that proposed by W.O. Stanley in 1953. After applying seven…

Recent research results strongly suggest that the theoretical problems of change measures have limited practical significance for measuring individual growth, and it is important to determine whether this is also the case for measuring school impact. Accordingly, in this study artifical data were used to assess the correlation between several…

A computer simulation procedure was developed to reproduce the overall pattern of results obtained in the Educational Testing Service Growth Study. Then simulated data for seven sets of 10,000 to 15,000 cases were analyzed, and findings compared on the basis of correlations between estimated and true growth scores. Findings showed that growth was…

The four goals of this project are outlined in some detail. First, a unit programed for self-instruction in nursing, entitled "An Introduction to Radiation Therapy" was revised and rewritten on the basis of knowledge gained from controlled use. The revised unit took less time, showed a decreased error rate and indicated greater learning. A second…

Aptitude-treatment interaction research is reviewed, with particular emphasis on the interaction of achievement and instructional method. Previous research has suggested that students with lower prior achievement require maximal instructional support. Recent research on this relationship is reviewed, as well as the relationship between…

To compare the effectiveness of individualized and lecture-discussion methods with a non-instruction (Control) method in developing turfgrass competencies in 11th and 12th grade students as measured by achievement in a battery of tests, teachers from 29 Michigan schools were randomly placed in three groups and attended workshops where they were…

This publication is primarily designed for educational practitioners who possess little or no training in conducting mail surveys or have not kept current on the present state of the art of survey methods and techniques. It is also intended to be a checking and comparing aid to ensure that important research considerations are taken into account.…
