A method is presented to use school-level attributes in sample description and random assignment of schools to conditions in drug prevention programs. Utility of archival data was examined using multivariate canonical techniques, and it was found that a small set of data could predict observed variations in drug use. (SLD)

A survey of 239 school-based speech-language pathologists revealed that respondents routinely supplement quantitative assessment procedures with language sample analyses, are sensitive to the effects of some contextual variables on sample representativeness, and use language sampling information to assist in planning intervention services.…

A modified time sampling procedure that measured behavioral rate and duration was used to record stereotypic and on-task responding in 11 students (ages 11-17) with severe emotional and behavioral disturbances. For both types of behavior, response duration exhibited less variability than response rate, and noncorrespondence between the two…

Analyzes the findings of J. Greene and data from Florida and suggests that the strong effects (significant improvement on test scores in schools threatened by vouchers) noted by Greene may actually be due in large part to sample selection, regression to the mean, and problems related to the aggregation of test score results. (Author/SLD)

Presentation of quantitative research on the family often suffers from a tendency to interpret findings on a statistical rather than substantive basis. Advocates the use of data analysis that lends itself to an intuitive understanding of the nature of the findings, the strength of the association, and the import of the result. (JPS)

Documents the methodology of the second follow-up interview of the Baccalaureate and Beyond Longitudinal Study, describing sample design, instruction development and data collection, response rates, efficacy of the survey instrument, and weights and design effects. (Author/SLD)

Describes an active learning approach to teaching sampling and measurement in an undergraduate course on research methods. Students complete a content analysis on desired partner attributes in personal advertisements. Discusses concerns and issues in relation to sampling, content analysis, and other potential problems. (CMK)

In this article, the author talks about an inquiry-based activity involving yeast, wherein students learned about cell size. The activity allows students to employ math connections and to learn experimental techniques while practicing microscope skills. The activity can be adapted for students at all levels of biology. The author presents details…

This chapter summarizes the most recent literature on the best practices of Web survey implementation and offers practical advice for researchers. (Contains 1 table.)

The purpose of this study was to develop a questionnaire that measures students' motivation toward science learning (SMTSL). Six scales were developed: self-efficacy, active learning strategies, science learning value, performance goal, achievement goal, and learning environment stimulation. In total, 1407 junior high school students from central…

Same-sex marriage, barely on the political radar a decade ago, is a reality in America. How will it affect the well-being of children? Some observers worry that legalizing same-sex marriage would send the message that same-sex parenting and opposite-sex parenting are interchangeable, when in fact they may lead to different outcomes for children.…

The longitudinal stability of eating problems and their relationships to risk factors were investigated in a representative population sample of 623 Norwegian girls aged 13-14 followed over 7 years (3 time points). Three eating problem symptoms were measured: Restriction, Bulimia-food preoccupation, and Diet, all taken from the 12-item Eating…

The National Science Concept Learning Study represented one of the largest and the most extensive surveys of its kind undertaken in Taiwan in recent years. A total of 36,093 students from the sixth, eighth, ninth, and eleventh grades participated in the main study. This paper provides the background information about the sampling and booklet…

This paper reports a causal-comparative study of science anxiety among Form Four students in Penang. The Wynstra's (1991) Science Anxiety Inventory (SAI), which consists of six factors (i.e., danger anxiety, science test anxiety, math and problem-solving anxiety, squeamish anxiety, performance anxiety, and science classroom anxiety), was…

There is much research that documents what many teachers know, that students struggle with many concepts in probability and statistics. This article presents two sample activities the authors use to help preservice teachers develop ideas about how they can use technology to promote their students' ability to understand mathematics and connect…
