Creativity is highly valued in both education and the workforce, but assessing and developing creativity can be difficult without psychometrically robust and affordable tools. The open-ended nature of creativity assessments has made them difficult to score, expensive, often imprecise, and therefore impractical for school- or district-wide use. To…

A negative association between symptoms of teacher burnout (e.g., emotional exhaustion) and students' academic outcomes has been demonstrated in previous research. Although, in theoretical models, it has been suggested that this association can be explained through changes in teachers' instructional behavior, these mediating processes have not yet…

Guided by Self-Determination Theory, we offer an integrative and fine-grained analysis of teachers' classroom motivating style (i.e., autonomy support, structure, control, and chaos) to resolve existing controversies in the literature, such as how these dimensions relate to each other and to educationally important student and teacher outcomes.…

This research introduces the "Mindfulness Mindset Scale," a concise and reliable tool designed to measure beliefs about the malleability of mindfulness skills. Study 1 (N = 285) revealed a single-factor structure through exploratory factor analysis, further validated in Study 2 (N = 286) using confirmatory factor analysis. Studies 3a (N…

For the international Trends in International Mathematics and Science Study (TIMSS2007) math and science motivation scales (self-concept, positive affect, and value), we evaluated the psychometric properties (factor structure, method effects, gender differences, and convergent and discriminant validity) in 4 Arab-speaking countries (Saudi Arabia,…

Knowledge of mathematical equivalence, the principle that 2 sides of an equation represent the same value, is a foundational concept in algebra, and this knowledge develops throughout elementary and middle school. Using a construct-modeling approach, we developed an assessment of equivalence knowledge. Second through sixth graders (N = 175)…

Three instruments designed to tap the self-system in normal IQ children were administered to 126 retarded children in mainstreamed and self-contained classrooms. Factor structures differed significantly from normal IQ results. The need to revise instruments for use with the retarded and to obtain social comparison information is emphasized.…

The construct validity of the Sequential Processing, Simultaneous Processing and Achievement scales of the Kaufman Assessment Battery for Children was supported by factor-analytic investigations of a representative national stratified sample of 2,000 children. Correlations provided insight into the relationship of sequential/simultaneous…

The Test of Reactions and Adaptation in College (TRAC), a measure of students' personal dispositions toward learning, is presented. Results from 2 different samples of college students (n=1,081) indicate acceptable psychometric characteristics for the TRAC. The TRAC predicted college success better than high school weighted academic average did.…
