Measures the effectiveness of a medically oriented educational game in increasing knowledge and decreasing young children's fears regarding common medical procedures. Paired t-tests indicated a significant increase in children's knowledge of health care concepts and decrease in fear of medical procedures after the game was played. (BB)

This study investigated differences in achievement for control groups learning college algebra using traditional classroom instruction methods compared to experimental groups using computer algebra tutorials for three precalculus topics. Two instructors each taught one control group and one experimental group. No significant differences were…

The regression-discontinuity design involving a treatment interaction effect (TIE), pretest-posttest functional form specification, and choice of point-of-estimation of the TIE are examined. Formulas for controlling the magnitude of TIE in simulations can be used for simulating the randomized experimental case where estimation is not at the…

An experimental class in introductory statistics (n=40) using simulation software at American University was compared to a traditionally taught control group (n=36) with respect to achievement and accrued beliefs about the benefits of the simulations. Results indicate significantly higher achievement scores for the experimental class with about…

The epidemiological method of case-control study is described, and its advantages and disadvantages are discussed for use in health program evaluation. Examples are reviewed, with a step-by-step description of the method. Potential applications are discussed, including worksite health promotions, screening programs, and large-scale public health…

The question of memory-based processing when transfer is delayed was addressed for 181 college students in a transfer-for-training paradigm. Results indicate that the use of a general and a specific schema for retrieval when memory-based processing is required to demonstrate transfer in a problem domain. (SLD)

This commentary argues that the study reported in EC 605 442, which indicated long-term gains for children with autism who experienced intensive behavioral intervention as preschoolers, needs to be replicated to be convincing, especially given the problem of nonrandom assignment of experimental and control groups. (JDD)

Discusses strategies researchers can use to help young children understand the research process and be better able to give informed consent. Argues that proxy consent from parents (historically used as a substitute for children's informed consent) does not fully meet the requirements of informed consent. (Author/GR)

Describes a computer-based instructional system called Stat Lady and reports the results of an evaluation study of undergraduates that tested the efficacy of learning probability from this program compared to a traditional lecture and a no-treatment control group. Aptitude treatment interaction is also investigated. (Author/LRW)

Describes how the University of Pennsylvania is testing a new way of teaching involving team-taught interdisciplinary courses on some its freshmen, while keeping others in a control group. (EV)

The use of the Internet is expected in foreign-language classrooms. The present study investigated and evaluated the effectiveness of a language course supplemented with online material for college-level Japanese learners. The study compared exam scores from students enrolled in traditional inclass instruction taught 5 consecutive days for 50…

In this cross-population study, we use narratives as a context to investigate language development in children from 4 to 12 years of age from three experimental groups: children with early unilateral focal brain damage (FL; N=52); children with specific language impairment (SLI; N=44); children with Williams syndrome (WMS; N=36), and typically…

The effects of a constructivist approach on academic achievement, self-concept and learning strategies, and student preference were investigated. The 76 six graders were divided into two groups. The experimental group was taught using the constructivist approach while the control group was taught using the traditional approach. A total of 40 hours…

The aim of the present study was to analyze the relationship between students' (100 children aged 8 to 12) help-seeking behavior and impulsivity. Help-seeking behavior was evaluated using a naturalistic experimental paradigm in which children were placed in a problem-solving situation and had the opportunity to seek help from the experimenter, if…

Inagaki and Hatano (2002) have argued that young children initially understand biological phenomena in terms of vitalism, a mode of construal in which "life" or "life-force" is the central causal-explanatory concept. This study investigated the development of vitalistic reasoning in young children's concepts of life, the human body and death.…
