This study of the effectiveness of electronic blackboards in three introductory sociology classes at the University of Regina tested the hypothesis that this microcomputer-based presentational technology would have a negative impact on faculty productivity due to the increased amount of preparation time, and a positive impact on the quality of…

A teaching aid appropriate for a beginning course on experimental design is presented. The aid is a numerical example which illustrates some of the theoretical interrelations among three competing design analysis strategies for estimating treatment effects in random assignment designs. The analysis strategies considered are analysis of variance…

Surveys the problems of coordinating theory with practice in applied linguistics and language teaching within the context of the disconnections of theory from practice in theoretical linguistics. Explores the basic frameworks of language science in terms of the applicability and proposes an alternative program. (49 references) (Author/CK)

Presents a case study of the effects of the Test of English as a Foreign Language (TOEFL) on two teachers in the same institution. The study investigates claims that the TOEFL exerts an undesirable influence on language teaching. Findings reveal that influences on what happens in class are more complex than unexamined beliefs about washback allow.…

Presents a laboratory activity for use during the first or second week of school that engages students in the basic principles of the scientific method. (PR)

The article suggests a method for organizing the research on teaching thinking and provides examples of indicators of teacher performance within various domains (hypothesis testing, argument assessment, problem solving, probabilistic thinking, and flexibility). Examples of empirical evidence supporting each indicator are included. (SM)

Recent research by Swain (2000a, 2000b, 1998, 1995), Swain and Lapkin (2001, 1998, 1995) and Kowal and Swain (1997, 1994) has examined the role of collaborative tasks in focusing immersion students' attention on the need for explicit knowledge of grammatical forms and lexical items in the production (especially written) of French texts. This is…

The aim of this study was to test the hypothesis that the different teacher groups of the Finnish comprehensive school differ from one another in their pedagogical thinking and practices. The authors of this article have conducted teacher in-service-training on integrated curriculum using new educational technology (interactive video and a…

The two objectives of this study were to compare the results of the teaching of written composition to high school students, using a problem-solving approach, with the results obtained using a traditional approach, and to determine if a problem-solving approach produces a significant difference in reflective thinking skills. Three null hypotheses…

This book provides information on what works in education, how teachers can find what works, how educational research can find its way into classrooms, and how teachers can apply it to help individual students. Data come from a meta-analysis of research studies on instructional strategies that could be used by K-12 teachers. Nine research-based…

Argues on the basis of Piaget's theory that self-regulated cognitive activity of the student plays a crucial role in the construction of logical reasoning strategies used in testing hypotheses. Proposes six sequences in the development of hypothesis-testing conceptions and provides alternatives. Also distinguishes three families of teaching…

Bumble bees are valuable pollinators of native and cultivated flora. Despite our knowledge of bumble bee nest site selection, most efforts to attract bumble bees to artificial domiciles have been met with limited success. Creating and evaluating artificial domiciles provides students an opportunity to investigate a real problem. In this lesson,…

We report on a study of the relationship between calculator technology and student learning in two introductory statistics class sections taught by the same instructor at the University of Texas at San Antonio. At the introduction of hypothesis testing and confidence intervals, one class section (A) was given graphing calculators capable of…

Data sharing among multiple lab sections increases statistical power of data analyses and informs student-generated hypotheses. We describe how to collect, organize, and manage data to support replicate and rolling inquiry models, with three illustrative examples of activities from a population-level biology course for science majors. (Contains 1…

A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…
