The aim of the present study was to investigate how situational interest develops over time and how it is related to academic achievement in an active-learning classroom. Five measures of situational interest were administered at critical points in time to 69 polytechnic students during a one-day, problem-based learning session. Results revealed that situational interest significantly increased after the problem stimulus was presented. Subsequently, situational interest gradually decreased but at the end of the day increased again. Testing a path model relating the situational interest measures showed strong (directional) interrelations. Moreover, situational interest was highly predictive for observed achievement-related classroom behaviors. The latter, in turn, proved to be a significant predictor of academic achievement. Aggregating situational interest over the day led to less accurate predictions of achievement-related classroom behaviors and academic achievement. Implications of these findings for situational interest research are discussed. 相似文献

This article report on the development and use of an analytical framework intended to map the language demands encountered by English learners as they engage in science performance assessments. Grounded in functional and interactional views of language and language use, the authors—two science education researchers and a language scholar—developed the framework via an inductive, iterative, and systematic review of written assessment materials associated with three fifth grade science performance tasks. The resulting Science Assessment Language Demands (SALD) framework is organized around three dimensions: participant structures, communicative modes, and written texts and genres that students are called upon to read and produce. The authors used textual analysis to conduct an expert review of the written documents associated with the three assessment tasks. The results indicate that the framework can be used to document a wide range of functional and interactional language demands involved in science performance assessments. The demands revealed by the SALD framework highlight both potential challenges facing English learners during science performance assessments as well as opportunities afforded by such assessments for demonstrating their knowledge and skills and further developing language proficiency. A major implication of the study is the potential use of the framework to evaluate the language demands and opportunities of science assessments used in classrooms with English learners. © 2010 Wiley Periodicals, Inc.

Postsecondary schools have traditionally relied on admissions tests such as the SAT and ACT to select students. With high school achievement assessments in place in many states, it is important to ascertain whether scores from those exams can either supplement or supplant conventional admissions tests. In this study we examined whether the Arizona Instrument to Measure Standards (AIMS) high school tests could serve as a useful predictor of college performance. Stepwise regression analyses with a predetermined order of variable entry revealed that AIMS generally did not account for additional performance variation when added to high school grade-point average (HSGPA) and SAT. However, in a cohort of students that took the test for graduation purposes, AIMS did account for about the same proportion of variance as SAT when added to a model that included HSGPA. The predictive value of both SAT and AIMS was generally the same for Caucasian, Hispanic, and Asian American students. The ramifications of universities using high school achievement exams as predictors of college success, in addition to or in lieu of traditional measures, are discussed. 相似文献

Genetic Change and Continuity from Fourteen to Twenty Months: The MacArthur Longitudinal Twin Study 总被引:3,自引:0,他引:3
Robert Plomin Jerome Kagan Robert N. Emde J. Steven Reznick Julia M. Braungart JoAnn Robinson Joseph Campos Carolyn Zahn-Waxler Robin Corley David W. Fulker J. C. DeFries 《Child development》1993,64(5):1354-1376
Genetic change as well as continuity was investigated within the domains of temperament, emotion, and cognition/language for 200 pairs of twins assessed at 14 and 20 months of age in the laboratory and home. The second year of life is marked by change rather than continuity: correlations from 14 to 20 months averaged about .30 for observational measures of temperament and emotion, about .40 for language measures, and about .50 for mental development. 2 types of genetic change were examined: changes in the magnitude of genetic influence (heritability) and genetic contributions to change from 14 to 20 months. In general, heritability estimates were similar at 14 and 20 months. Evidence for genetic influence on change from 14 to 20 months emerged for several measures, implying that heritability cannot be equated with stability. Analyses of continuity indicated that genetic factors are largely responsible for continuity from 14 to 20 months. 相似文献
