The aim of this study was to examine the role of motivational beliefs in mediating the relationship among perceived teacher support, learning strategy use, and student achievement. The author analyzed the Programme for International Student Assessment mathematics scores and questionnaire responses of 4,855 15-year-old students in Turkey via…

Sample size determination is an important issue in planning research. In the context of one-way fixed-effect analysis of variance, the conventional sample size formula cannot be applied for the heterogeneous variance cases. This study discusses the sample size requirement for the Welch test in the one-way fixed-effect analysis of variance with…

The purpose of this study was to extend the research on achievement goal theory by examining the measurement and understanding of goal structures using teacher-reported data. A large number of elementary, middle, and high school teachers completed an online survey that included items assessing their use of instructional practices associated with…

In this study, the authors aimed to examine 8 of the different methods for computing confidence intervals around alpha that have been proposed to determine which of these, if any, is the most accurate and precise. Monte Carlo methods were used to simulate samples under known and controlled population conditions wherein the underlying item…

The authors investigated the relations among reasons students gave for why they would not cheat in response to a cheating vignette, self-reported cheating, and the extent to which students take responsibility for promoting academic integrity. The authors surveyed 1,086 graduate and undergraduate students. Students who said they would not cheat…

The challenges in teaching and learning of biological evolution continue to be documented (NAS, 2008). Developers of science standards continue their work to increase emphasis on evolution. Although gains have been made, many K-12 science curricula focus on microevolution (i.e., natural selection, genetic drift), and a more limited effort is in…

Computer-supported collaboration by spatially distributed group members still involves interaction problems within the group. This article presents an empirical study investigating the question of whether computer-supported collaborative problem solving by spatially distributed group members can be fostered by evoking knowledge and information…

This qualitative study investigated the achievement goal orientations of a group of all male pre-med students attending a small, urban undergraduate college. Semi-structured interviews examined under what circumstances students adopted extrinsic goals, mastery goals, or a mixture of the two. Findings indicated that while nearly all students…

Self-determination theory provided the theoretical framework for a cross-sectional investigation of elementary and junior high school students' autonomous motivation for homework. More specifically, the study focused on the role of teachers' support of students' psychological needs in students' motivation for homework in the two school systems.…

This study explored the occurrence of self-conscious emotions in response to perceived academic failure among 4th-grade students from the United States and Bulgaria, and the author investigated potential contributors to such negative emotional experiences. Results from structural equation modeling indicated that regardless of country, negative…

The authors conducted 2 experiments with children from a reservation community. In Experiment 1, 45 third-grade children were randomly assigned to the following reading strategies: (a) "reread," in which participants read each sentence of a story and then reread it; (b) "observe," in which participants read sentences and then observed an…

The authors examined the use of effect sizes across an entire field, satisfying a goal J. Cohen (1997) suggested. They analyzed the extent to which researchers had reported effect sizes in the 5 major journals on gifted education between 1996 and 2005 and compiled data on the types of manuscripts published, whether researchers reported effect…

Federal standards established in 1997 allow respondents to select multiple-race categories. These new standards changed the single-race subgroup definitions that the government has required since 1977. Meta-analysis, research on long-term assessment trends, and other research involving historical comparisons must account for the definitional…

Using M. L. Maehr's (1984) theory of personal investment, the authors investigated associations among perceived peer relationships and achievement motivation during science class. Middle school and high school students (N = 253) completed a self-report questionnaire assessing peer classroom climate, achievement-related beliefs and values of a best…

Recent interest in epistemic beliefs has given way to a proliferation of new measures. Yet, little is known about the psychometric properties of various measures when used with diverse populations. In this study, the authors explored the psychometric properties of a measure of existing epistemic beliefs, the Domain-Specific Belief Questionnaire…
