Teacher knowledge and instructional expertise have been found in correlational and pre- and post-test studies to be related to student reading achievement. This article summarizes data presented in this special issue and additional research to address four questions: (a) What do expert reading teachers know? (b) Why do teachers need to acquire…

Objective: Determine child care providers' infant feeding knowledge, attitude and behavior changes after viewing the infant feeding Web site and determine the effectiveness of the Web site and bilingual educational materials. Design: Intervention and control groups completed an on-line pretest survey, viewed a Web site for 3 months, and completed…

The purpose of this study was to examine the effectiveness of three different interface types on Web-based instruction: a text-based interface, a graphical interface and a metaphorical interface. In order to determine differences among three interface groups, we compared learning performance, cognitive load, usability, and appeal with various data…

Working with two teachers and thirty-four high school seniors, the authors developed procedures and assessments to teach ethics in an American high school civics class. This approach requires high school students to discover an agreement or convergence between Kantian ethics and virtue ethics. The authors also created an instrument to measure…

The article summarizes results from two experimental studies on reactivity. In the first experiment, 24 college-age participants received a computerized treatment that delivered a grammar lesson, practice, and feedback on assignment of semantic functions in Latin. Verbalizations did not induce reactivity on accuracy, but they slowed down posttest…

This study examined how 2 kinds of help when learning from text and pictures (mapping support and instructional guidance through prompts) influence the coherence formation process of integrating information into a mental model. It also explored spatial abilities and working memory span as potential moderators. In a computer-based setting, 84…

Animal species identification is often emphasized as a basic prerequisite for an understanding of ecology because ecological interactions are based on interactions between species at least as it is taught on the school level. Therefore, training identification skills or using identification books seems a worthwhile task in biology education, and…

Within the field of adult education a paradigm shift, or at least a paradigm creep, is taking place as a result of advances in technology. This comprehensive, quasiexperimental study examining the efficacy of online education (OE) for professional development, conducted among American police officers, compares OE to traditional delivery methods,…

Although provider knowledge is a potential barrier in the dissemination of evidence-based services for youth, research in this area is currently limited by a lack of instrumentation. The present study examined the utility of the Knowledge of Evidence-Based Services Questionnaire (KEBSQ), a 40-item self-report measure designed to assess reporter…

This study compared learning for fifth grade students in two math homework conditions. The paper-and-pencil condition represented traditional homework, with review of problems in class the following day. The Web-based homework condition provided immediate feedback in the form of hints on demand and step-by-step scaffolding. We analyzed the results…

Experimental designs are distinguished as the best method to respond to questions involving causality. The purpose of the present paper is to explicate the logic of experimental design and why it is so vital to questions that demand causal conclusions. In addition, types of internal and external validity threats are discussed. To emphasize the…

The aim of this study was to examine the effect of teaching designed to consider grade 9 students' misconceptions about simple electric circuits on conceptual change. Students' misconceptions were determined by using a conceptual understanding test consisting of eight open-ended questions and semi-structured interview technique. Conceptual…

This study examined the effectiveness of worksheets while learning about biodiversity in a natural history museum. Despite the frequent use of worksheets by school classes during out-of-school activities, their effectiveness in enhancing knowledge acquisition has been addressed by relatively few empirical studies. 148 Austrian grammar school…

Sixty undergraduate students who had completed at least one semester of jazz improvisation were assigned to either: (a) physical practice (PP); (b) mental practice (MP); (c) combined 66 percent PP and 33 percent MP (66%PP:33%MP); and (d) combined 33 percent PP and 66 percent MP (33%PP:66%MP) groups. Subjects were to perform a 3-1-7-5 tonal pattern…

This article proposes an instance-based theoretical framework to account for the influence of both contexts and definitions on learning new word meanings and reports 2 studies that examine hypotheses about learning from context. One is that variation in contexts is important for allowing core meaning features of a word to emerge. The second is…
