A review and meta-analysis were made of placebo control groups in educational experiments. In all, 125 studies were clustered into procedures that included (1) explicit manipulation of attentional elements; (2) explicit description of the placebo activity plus implied reference to attention; and (3) exclusive reference to the activity. (SLD)

Presented a categorization of types of science education research, their possible contributions to cognitive science, and the potential of results from cognitive science for enriching the science education research accounts. Explored the relationship of an example of cognitive work to cognitive science. (15 references) (Author/JRH)

New methods for comparing the medians corresponding to independent treatment groups are suggested. Procedures are based on the estimator of F. Harrell and C. Davis in conjunction with a modification and extension of the bootstrap calibration technique suggested by W. Loh. Data from two groups provide an illustration. (SLD)

Issues are raised about the Council for Learning Disabilities Research Committee's standards for describing research subjects, including justification for the recommended standards, relationship between description of subjects and probability of replication, and impact of the type of research on subject description standards. Recommendations are…

This article contends that educational researchers need to realize that the research process itself is an unregarded intervention beyond any intentional treatment effects or secondary effects on the research participants or other stakeholders. Implications are discussed for conducting and reporting experimental and qualitative research to increase…

Purpose: We investigated the feasibility of using a "wash-and-dry" toilet in the nursing home. Design and Methods: We used a controlled comparison baseline-versus-treatment design with 22 female nursing home residents aged 75 and older living in a 562-bed, not-for-profit nursing home facility in Maryland. The Luscence Luxury Lavage…

This study investigated the effect of using infant simulators with a structured, competency-based curriculum by examining the infant care behavior of adolescents and their attitudes toward parenting and sexual behavior. The sample of 236 students included 112 males and 124 females ranging in age from 14 to 18 years. This sample was randomly…

Discussion abounds in the literature as to whether aphasia is a deficit of linguistic competence or linguistic performance and, if it is a performance deficit, what are its precise mechanisms. Considerable evidence suggests that alteration of nonlinguistic factors can affect language performance in aphasia, a finding that raises questions about…

This study focuses on the ability of high-school chemistry students, who learn chemistry through the inquiry approach, to ask meaningful and scientifically sound questions. We investigated (a) the ability of students to ask questions related to their observations and findings in an inquiry-type experiment (a practical test) and (b) the ability of…

Background: This paper is the result of our interest in preventing adaptation problems (delinquency, academic failure and absenteeism at school, drug use, etc.) in young children and adolescents at risk, as well as the need to develop effective programmes adapted to the population in the Balearic Islands (Spain). Purpose: The objective of this…

In 2001, the U.S. Department of Education and the Ministry of Education in China entered into a bilateral partnership to develop a technology-driven approach to foreign language learning that integrated gaming, immersion, voice recognition, problem-based learning tasks, and other features that made it a significant research and development pilot…

The processes behind the transition from consistently failing tests of false belief understanding to consistently passing the tests was investigated by tracking changes in children's mental state understanding. Participants were 42 children (aged 3;1 to 4;3). There were two conditions; an experimental condition in which children were tested on a…

This study explored the effects of a reciprocal teaching intervention designed to enhance the lecture comprehension skills of college students. Forty low-verbal ability students and 40 high-verbal ability students (as measured by SAT scores) were chosen for the study and randomly assigned to experimental or control groups. The experimental groups…

Objectives: This study investigated the efficiency of a social work care coordination model for stroke patients. Care coordination addresses patient care and treatment resources across the health care system to reduce risk, improve clinical outcomes, and maximize efficiency. Method: A randomly assigned, pre-post experimental design measured…

The effects of training in Universal Design for Learning (UDL) on lesson plan development of special and general educators in a college classroom environment were investigated. A true experimental group design with a control group was used for this study. A one-hour teacher training session introduced UDL to the experimental group; the control…
