The authors investigated predictive relationships among student characteristics that influence motivation for learning and achievement. Participants were students (N = 900) from all 4 grade levels in 18 rural public high schools in the southwestern United States. The authors used AMOS 4.0 (J. L. Arbuckle & W. Wothke, 1996) to test a hypothesized…

In this study, the authors assess several strategies created on the basis of the Mantel-Haenszel (MH) procedure for conducting differential item functioning (DIF) analysis with small samples. One of the analytical strategies is a loss function (LF) that uses empirical Bayes Mantel-Haenszel estimators, whereas the other strategies use the classical…

The authors apply current influential models from the motivational literature to develop the comprehensive factors influencing teaching choice (FIT-Choice) scale, to measure factors influencing the choice to teach for beginning preservice teacher education candidates. They validate the scale using 2 large cohorts (N = 488; 652) and describe the…

In this cross-national study, the authors compared mathematics self-efficacy beliefs of American (n = 107) and Taiwanese (n = 188) middle-school students for level and calibration (accuracy and bias). Taiwanese students surpassed Americans in math achievement. American students evidenced slightly higher self-efficacy levels for easy math items but…

SThe importance of students' sense of school belonging for many adaptive outcomes is becoming well established; however, few researchers have focused on college-aged populations. In this study, the authors examined associations between undergraduate students' sense of class belonging and their academic motivation in that class, their sense of…

On the basis of an integrated theoretical approach to achievement motivation, the authors designed this study to investigate the potential influence of mastery goal, performance-approach and avoidance-approach goals, individual interest, and situational interest on students' learning in a physical education softball unit. The authors collected and…

Students (N = 124) viewed 14 timed Web pages that distinguished 14 confusing word pairs. In a 2 x 2 factorial design, the authors gave all of the students matrices containing representational pictures for each pair of words, as well as examples of each word in use. One factor in the design was the absence or presence of rules of usage for each…

In this study the authors investigated the use of 5 (i.e., Claudy, Ezekiel, Olkin-Pratt, Pratt, and Smith) R[squared] correction formulas with the Pearson r[squared]. The authors estimated adjustment bias and precision under 6 x 3 x 6 conditions (i.e., population [rho] values of 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9; population shapes normal, skewness…

The authors investigated what and how instructional practices are related to students' motivation and performance in writing. The participants were 6 teacher interns and their (N = 209) secondary-school students in Hong Kong. In a 3-session instruction unit, the teacher interns taught their students how to write an expository essay. The students…

The author examined the effectiveness of training in symbolic logic for improving students' deductive reasoning. A total of 116 undergraduate students (approximately equal numbers of men and women) enrolled in 1st-year university philosophy courses in symbolic logic participated in 2 studies. In both studies, students completed booklets of…

The authors used an experimental design to compare the effectiveness of unstructured collaborative practice with individual practice on achievement on a complex well-structured problem-solving task. Participants included postsecondary students (N = 257) from a liberal arts college serving primarily nontraditional students and from 2 state…

Complex survey designs often employ multistage cluster sampling designs and oversample particular units to ensure more accurate population parameter estimates. These issues must be accommodated in the analysis to ensure accurate parameter estimation. Incorporation of sample weights in some statistical procedures has been studied. However, research…

The authors investigated the development of metacognitive skill (MS) of 43 children from preschool to the 2nd grade (6-8 years of age) in a problem-solving situation. The children's skill to direct, guide, and monitor their performance in a play-like problem-solving context was evaluated in 3 experimental groups of preschool children with high,…

In this study, the authors introduce a new way to analyze cognitive change during social interactions, based on the mental model theory of reasoning. From this approach, cognitive performance can be improved for solving problems that require multiple models when participants in a social interaction group maintain qualitatively different models of…

The authors describe and illustrate 6 factors that affect the size of a Pearson correlation: (a) the amount of variability in the data, (b) differences in the shapes of the 2 distributions, (c) lack of linearity, (d) the presence of 1 or more "outliers," (e) characteristics of the sample, and (f) measurement error. Also discussed are ways to…
