Replicating previously reported empirical research is a necessary aspect of an evidence-based field of special education, but little formal investigation into the prevalence of replication research in the special education research literature has been conducted. Various factors may explain the lack of attention to replication of special education…

The paper discussed the difficulties and problems in experimental researches in educational technology, such as misunderstanding in teachers' concept, disjointedness between theory and practice, inadequate understanding of dialectics in experimental educational technology researches, research project selection and theoretical hypothesis formation…

Interactive Research and Development on Teaching (IR&DT) is an alternative Research and Development (R&D) strategy that probes the questions, problems, and concerns of classroom teachers in a nonlinear manner. Each of the primary functions of traditional R&D--research, development, dissemination, and implementation--are performed…

An experimenting society is one that vigorously tries out proposed solutions to recurrent problems and then tries other alternatives if evaluation shows that previous efforts are ineffective or harmful. Methods that social scientists could use if the experimenting society becomes a reality are explored. (SLD)

To tailor instruction to levels of learner proficiency in a domain in adaptive learning environments, rapid on-line methods of assessing learner knowledge and skills are required. Cognitive studies indicate that major factors in expert performance are organised structures in the person's knowledge base. Measuring different levels of acquisition of…

The program of systematic evaluation of variables associated with visual learning was initiated in 1965 to investigate the impact of variables linked to effective, efficient use of instructional visual materials. A prototype experimental package, containing a specific unit of cognitive content, learner achievement objectives, four individual…

The methodology used during the 2-year project involving 14 case studies of rural education improvement programs consisted of 4 sets of overlapping activities: (1) gearing up and completing the study design; (2) site visits, data collection, and case study write ups; (3) data analysis; and (4) technical assistance. The gearing up period was…

The New Orleans Parent-Child Development Center (NOPCDC) was funded four years ago to develop and evaluate the effectiveness of a model of parent education. The ultimate goal was to prevent the effects of poverty on human development. The parent education program was designed to increase the mother's knowledge and understanding about child…

This paper describes the research strategies employed in the Dutch Technology Enriched Schools (TES) project, which was initiated in 1987 to introduce computers into secondary education, to encourage extensive and intensive use of computers in a small number of secondary schools, and to study the effects of computer use on the classroom, the…

Instructional research now in advanced formulation at Southwest Regional Laboratory for Educational Research and Development is used to illustrate what a system of the IDCMS type must be able to do to acceptably support execution of such research. Of particular interest here is the event-control system which allows different subjects who…

The Philadelphia City Schools engaged in a four-year program to develop and test dual audio television, a way to help children learn more from the massive amounts of time they spend watching commercial television. The format consisted of an instructional radio broadcast which accompanied popular television shows and attempted to clarify and…

The goal of the POR FIN research design was to develop a language-based curriculum emphasizing the audiolingual approach and integrating academic and social-functioning subject matter. The modular curriculum is designed so that each lesson is independent and complete in itself, and provides a high degree of motivation, retention, and achievement…
