The recurrence of problems in connection with research and development (R and D) activities supported by the Audio-Visual Center of Indiana University led to the development of a proposed control system. This paper lists those problems and examines the assumptions which must be met by the control system--that the Center will support all types of R…

Several experiments investigating the relationship between frequency of testing and learning are reviewed, and features of design which could have influenced outcomes are discussed. A study on test frequency is presented, in which relevant variables, apparently not considered in previous research, are controlled. Results indicate that moderate…

AN OCCUPATIONAL RESEARCH AND DEVELOPMENT COORDINATION UNIT WAS ESTABLISHED TO STIMULATE VOCATIONAL RESEARCH, TO INITIATE AND COORDINATE INSTITUTIONAL RESEARCH, TO PROVIDE TECHNICAL ASSISTANCE IN PROPOSAL DESIGN, TO WRITE PROPOSALS, AND TO ACT AS LIAISON BETWEEN FEDERAL AND OTHER FUNDING AGENCIES. THE IMPLEMENTATION OF THIS PROGRAM OF ACTIVITIES…

Attrition, or the loss of study subjects, confounds the subject identification process. Design attrition occurs when subjects initially involved in the study are excluded because of changes in study focus or rationale. Data collection attrition occurs when subjects are excluded because they were not contacted by the data gatherer, or because the…

Notes that black people are extremely adept at survival and suggests that historians need to identify and emphasize the mechanisms by which this survival has been possible. (Author/AM)

Notes that the important issues in current bilingual education in the United States are of two major sorts. One of these is concerned with the operation of existing bilingual programs, and includes problems of adequate teaching staff and proper integration of programs. The other deals with the perceived aims and purposes of bilingual education…

Research in art education must deal with the structure-in-process of creating, including both cognitive and intuitive approaches of human understanding. The Structural-Existential (S-E) Model can analyze this paradox. To exemplify the theoretical arguments, the author uses excerpts from contexts of creating in art. (SJL)

In discussing the problems of evaluating Canadian bilingual immersion programs, six related aspects are separately considered: (1) the research design, (2) the students tested, (3) the nature of the tests used, (4) the methods of analysis employed, and (5) the interpretation of findings. (Author/SJL)

The roles of summative and formative evaluation as scientific approaches to theory building in instructional television programing for children are examined through a review of research studies. The author contends that the bias toward summative evaluation has been premature in an area of inquiry, where most of the variables are yet to be…

Discusses a study of the relationship between contributions to scientific knowledge and the application of those contributions. Data collected from a U.S. Forest Service project indicate that the impact of research and development is greater when the knowledge-creation process is seen as a response to client needs rather than when researchers are…

In discussing the past, present, and future of research in teacher effectiveness, this article notes that researcher's conceptions of teacher effectiveness has determined the nature of the research and the usefulness of the findings; process-product research can produce reliable information; the tools needed to build a knowledge base for effective…

Trotman (EJ 168 902) indicated that Black and White families of similar socioeconomic status differ widely in intellectual home environment, and suggested the nonutility of socioeconomic status as a control in racial comparisons of IQ. The validity of Trotman's conclusions is questioned, both for methodology and results. (Author/BH)

Three aspects of desegregated schools, dealt with in the other articles in this volume, are discussed: the relation of stratification in the community to social relations and academic identities in the schools; the distinction between school desegregation and school integration; and the problem of time lag in the study of emergent social…

Points out weaknesses in research studies purporting to show that there is no transfer value to the teaching of grammar; presents 21 pointers to aid in establishing a good grammar program. (DD)

The path to increasing certainty becomes not the single excellent study, which is nonetheless weak in one or more respects, but the convergence of findings from many studies, which are also weak, but in many different ways. The dissimilar or nonreplicated weaknesses leave the replicated finding more secure. (Author/IRT)
