Breast cancer ranks as the second-leading cause of death for women. Until recently the American Cancer Society advocated teaching breast self-examination (BSE) procedures. The Susan G. Komen Breast Cancer Foundation, active in the fight against breast cancer, continues to support educational efforts to teach breast self-examination skills to…

Research indicates that the acquisition of phonemic awareness and phonic skills is highly correlated with later success in learning to read. Numerous studies support the hypothesis that deaf and hard-of-hearing children are able to utilize alternative systems to develop phonological awareness that are not dependent on the ability to hear sounds or…

The Present Article describes the effectiveness of stress management classes in decreasing perceived stress among Deaf adults. Deaf adults may experience unique stressors, in addition to circumstances associated with increased stress in the general population. The Perceived Stress Scale (S. Cohen, Kamarck, & Mermelstein, 1983) was used as a…

A subcategory of computer-assisted instruction (CAI), games have additional attributes such as motivation, reward, interactivity, score, and challenge. This study used a quasi-experimental design to determine if previous findings generalize to non simulation-based game designs. Researchers observed significant improvement in the overall population…

This guide is designed as a resource for leaders and evaluators of K-12 online learning programs. In this guide, the term "online learning" is used to refer to a range of education programs and resources in the K-12 arena, including distance learning courses offered by universities, private providers, or teachers at other schools;…

This study has been carried out in order to determine the effect of computer animations in teaching acid and base topics in science and technology courses on the academic success of the primary school students and the opinions of students related to teaching with the animations. This research was conducted by the participation of 55 students from…

In this article, the effectiveness of pre-service training that focuses on collaborative consultation and positive behavior support for treatment of challenging behaviors is evaluated. The effectiveness of an 8-month training program is evaluated for three participant groups: (a) 16 advanced undergraduate and master's-level students who received…

In Taiwan, lectures are commonly used for younger students to learn their own language, which is traditional Chinese. Passively listening to lectures has led to this group of students making such mistakes as forgetting strokes and word meanings, combining phrases to create incomprehensible blurs of information, and switching radicals with phonetic…

Objective: Develop, implement, and evaluate an intervention (a guided experiential assignment) to improve nutrition students' attitudes toward working with older adults. Design: A quasi-experimental design with an additional qualitative component (mixed methods). Setting: A North Central land-grant university. Participants: 100 college students…

This study investigates the effects of the three major factors of Suggestopedia--music, relaxation and suggestion--on the students' affect and development of communicative competence in tertiary Japanese language classes. A review of literature on Suggestopedia, the original form of Accelerated Learning (AL), shows that its effects are…

Since the passage of the first Charter School Law in Minnesota in 2001, there have been many studies that have examined the effect of Charter schools on student achievement with very mixed results. The Missouri legislature passed legislation in 1998 permitting the establishment of charter schools in a metropolitan school district or in an urban…

Analysis strategies are discussed for the nonequivalent control group design when three models of continuous natural growth are known. For Model I type natural growth it was shown that the fan spread hypothesis always holds, and Analysis of Covariance (ANCOVA), Analysis of Variance (ANOVA) of Residualized Gain Scores, and ANOVA of Standardized…

Since usually no defensible option for performing a task within quasi-experimentation is unbiased, it is desirable to select several options that reflect biases in different directions. The benefits of applying a critical multiplism approach to causal hypotheses, group nonequivalence, and units of analysis in quasi-experimentation is discussed.…

Confusion about the meaning of validity in quasi-experimental research can be addressed by carefully relabeling types of validity. Internal validity can more aptly be termed "local molar causal validity." More tentatively, the "principle of proximal similarity" can be substituted for the concept of external validity. (Author)

The evaluation of competing analysis strategies based on estimator bias and variance is demonstrated using gains in standard scores and analysis of covariance procedures for quasi-experiments conforming to the fan-spread hypothesis. The findings do not lead to a uniform recommendation of either approach. (Author/JKS)
