The scientificalization of educational research methods was always the most predominant in the two tides of educational experiment in China in the twentieth century, the result of which was unexpectedly dissatisfactory, because researchers misunderstood the connotation of scientificalization in such a degree that resulted in the worship for…

Explains the characteristics and importance of random assignment in experimental research on education. Considers factors supporting causal inferences, the nature of "assignment units," differences between random sampling and random assignment, the characteristics of randomization tests, forms of random assignment, and effects of experimental…

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

This article uses a parable to compare qualitative (interpretive) and quantitative (experimental) methods in child language research. Two hypothetical young researchers both investigate question-asking behavior of children with autism. Five different possible endings to the parable illustrate various relationships among research approaches and…

This reaction to Duchan (EC 607 918) warns against a strict dogmatic adherence to either a qualitative or quantitative research approach and argues that far more important than methodology per se are choice of research question and appropriateness of the methodology to the problem under investigation. Examples in speech-language pathology are…

Suggests that experimental studies are valuable in analyzing children's language development. Criticizes the scarcity of experimental and naturalistic investigation into preschool language development. Calls for long-term study of continuity and discontinuity in children's school and home learning and between different school stages. Observes that…

Criticizes the way organic chemistry teaching laboratory experiments are approached from the viewpoint of physical chemistry. Compares these experiments to cooking. Stresses that what matters is not the practice of the finger skills of organic chemistry but practice in the style of thinking of organic chemists. (CW)

Laboratory simulations combine the strengths of lab experiments and field studies while avoiding many of their liabilities. They permit the emotional involvement, the time needed for development of norms and interlocked systems of interaction, and the broad range of variables typical of field settings, yet allow for experimental controls and…

This analysis of the relationship between science education and technology over the past 15 years focuses on lessons learned from research on learning and instruction, the relationship between the teacher and technology, and the influence of technological advances on educational practice. Five conclusions are drawn: (1) courseware authoring…

Describes the rationale for using computer-assisted videodisc lessons to enhance introductory chemistry courses at University of Illinois, and presents sample lessons to illustrate what students see and do as they proceed through the lessons. Lesson construction and use are reviewed. (MBR)

Discussed are the two sides to the question of laboratory dissections. Alternatives to dissection are proposed as well as the importance of incorporating dissections in a science curriculum. (KR)

The educational potential of agriculture stems from the diversity and tangibility of its components. As a science based human activity, it may provide the educator with a unique combination of educational opportunities in a context which is authentic and accessible to the pupil and to the teacher. (JHZ)

The paper discusses a number of issues concerning the practical usefulness of cognitive psychology research, and presents a case study of pilot training methods to illustrate a model of research processes that produces outcomes which contribute to both basic and applied research goals. Research studies are described as varying in the degree to…
