Discipline-based education researchers have a natural laboratory--classrooms, programs, colleges, and universities. Studies that administer treatments to multiple sections, in multiple years, or at multiple institutions are particularly compelling for two reasons: first, the sample sizes increase, and second, the implementation of the treatments…

This study investigated the dynamics of complex interactions within inquiry-based (IB) discussions by visualizing patterns using social network analysis. Researchers explored network measures when learners participated in inquiry-based discussions with Practical Inquiry Model (PIM) and non-PIM questions while playing the weekly moderator's role.…

"Spatial analysis" is an analytic method that uses location-based variables or maps to understand how places, the characteristics of places, and the people and things in places are arranged in space, as well as the reasons for these arrangements. This resource focuses on how spatial analysis can be used to understand early care and…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

This brief is directed to researchers and adds to the research base about instructional practices that are related to student achievement. Additional evidence on these relationships can suggest specific hypotheses for the future study of such instructional practices, which, in turn, will provide research evidence that could inform professional…

Although there are an increasing number of youth development programs that aim to empower young people, there is a dearth of psychometrically sound measures that can be used to assess flexible youth-led organizing and participatory research approaches that tackle a wide range of social and community problems. This study developed and tested…

Background/Context: Previous research has pointed to the dismal state of secondary education in California and its implications for college access. These studies identified the extent to which disparities in access and outcomes in California are correlated with school demographics and the relative levels of segregation that exist in California's…

In this Appendix, we provide details about the data used for the current study, the curricula used in the classrooms from which data were collected, and the current study's methodological approach. (Contains 14 tables and 5 footnotes.)[For full report, see ED544189.]

Purpose: Although conflict has traditionally been considered destructive, recent studies have indicated that conflict management can contribute to effective teamwork. The present study explores conflict management as a team phenomenon in schools. The author examined how the contextual variables (task interdependence, goal interdependence) are…

This investigation examines teacher and child perceptions of teacher-child relationships and early school adjustment among children (N = 157) in low-income urban schools. Consistent with prior research, findings indicated that teacher-child relationships were associated with early school adjustment; however, the strength of this association varied…

Despite the hypothesized link between arousal and behavior in persons with autism, there is a lack of idiographic research that directly assesses arousal responses to novel stimuli or social situations in this population. The current study used heart rate as a measure of sympathetic activity to compare arousal responses to the presentation of…

Describes the methodology of White's survey of the perceived quality of library education programs, and examines the validity of using the results to rank library schools. The correlation between perception rankings and number of graduates per school are presented and discussed as a possible biasing factor in White's results. (CLB)

Statistics on book budgets, population served, and collection size of individual public libraries in New York State were correlated with their circulation data to examine efficiency of scale for mid-size libraries. Findings show that circulation increases erratically with increased book budgets and size of population, but consistently with…

Beyond cases reported to authorities, little knowledge exists on the types, amount, and effects of childhood victimization. Through a national survey of adolescents, researchers examined the prevalence of sexual assault, physical assault, physically abusive punishment, and witnessing an act of violence and subsequent effects on mental health,…

This study explored patterns of pastime activities that stand as alternatives to television viewing among middle school children. Findings are compared with those of Robinson's study (1981) for alternative media, video games, and sleeping variables, as well as dichotomous measures for group membership, playing a musical instrument, and hobbies.…
