The accelerating diffusion of broadband Internet access provides many opportunities for the development of pedagogically robust Web-based instruction (WBI). While the supporting technology infrastructure of broadband disseminates, the attention of academic researchers focuses upon issues such as the drivers of student usage of WBI. Specifically,…

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,…

Videoconferencing (VC) technology has been used successfully to provide psychiatric services to patients in rural and otherwise underserved settings. VC-based diagnostic interviewing has shown good agreement with conventional face-to-face diagnosis of dementia in several investigations, but extension of this technology to neurocognitive assessment…

The outcome results of home visiting programs have been mixed and modestly encouraging at best. To further understand this phenomenon it is important to understand what influences participation in home visiting programs. This study explores the relationship between housing stability and level of participation in an Early Head Start home visiting…

Attitudinal data tested hypotheses that students have more positive attitudes toward science when teachers regularly emphasize hands-on laboratory activities and when students more frequently experience higher levels of experimentation or inquiry. The first predicted that students would have more positive attitudes toward science in classrooms…

Nicotine replacement therapy (NRT) repeatedly has been shown to improve smoking treatment outcome. The major mechanism posited for this improvement in outcome is that NRT reduces nicotine craving and withdrawal. The authors tested this hypothesized mechanism of action using real-time data on craving and withdrawal, collected by ecological…

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…

This study sought to determine the extent of the serial position effect in listening to French and to specify the relationship between problem areas in listening to French and the position effect. The study addressed three hypotheses relative to the serial position effect and listening to French: (1) Was there a significant difference between the…

Science process skills such as observing, classifying, inferring, interpreting, predicting, and hypothesizing can all be classified as a sub category of thinking skills. This book is part of the series "Strategies for Learning" that focuses on the step-by-step development and application of thinking skills as a vehicle for learning science. The…

This study examined the impact of being an adult child of an alcoholic family (COA) on one's personal and interpersonal adjustment. First, it was predicted that because of difficulties with interpersonal trust, COAs would express less of a need for social approval compared with non-COAs. A related prediction was that COAs would report being…

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…

Tables for testing clinical hypotheses about counseling clients are presented, and their use is described. Primary uses are determining a critical value or cutoff score on a predictor that can be used to classify an individual as a member of a clinical group, and instructing those unfamiliar with the limitations of tests about the conditions under…

This study was designed to determine whether there was a difference in either the overall frequency or the frequency of specific types of student verbal interactions under three conditions: (1) teleconferenced instruction where students had two-way audio and video contact with the instructor; (2) teleconferenced instruction where students had only…

Too few researchers understand what statistical significance testing does and does not do, and consequently their results are misinterpreted. This Digest explains the concept of statistical significance testing and discusses the meaning of probabilities, the concept of statistical significance, arguments against significance testing,…
