Students’ goal strivings are known to be connected with important outcomes, both academically and with regard to individual well-being. In spite of their importance, our knowledge of factors contributing to their early development is rather limited. In this longitudinal study on school beginners (N = 212), we focused on the interrelationships between achievement goal orientations (mastery; performance-approach; performance-avoidance; work-avoidance) and two temperamental sensitivities that appear relevant for the developing sense of mastery and performance in the school setting: interindividual reward sensitivity (reward derived from social approval and attention) and sensitivity to punishment (propensity to perceive cues of potential threat in the environment, and react with withdrawal and avoidance). The data were collected over the first three school years, from grade 1 (7–8 years) to grade 3 (9–10 years), and analysed using PLS-SEM. As expected, both temperamental sensitivities and achievement goal orientations remained relatively stable over time. Interindividual reward sensitivity was related negatively with mastery and positively with performance-approach and performance-avoidance orientations, from the first through to the third year. Punishment sensitivity had a positive effect on performance-avoidance orientation, and indirect, reciprocal, negative effects with performance-approach orientation. The findings provide new knowledge on early relationships between temperament and goal strivings. Interindividual reward sensitivity appears consistently associated with performance concerns and decreased mastery strivings. Such connections may have long-standing negative influence on students’ educational trajectories, and point to the importance of acknowledging individual differences in temperament and their role in motivation and learning.

Organizational culture and effectiveness in two-year colleges   总被引:2,自引:0,他引:2  
The central purpose of this study is to determine the extent to which the effectiveness of a nationally representative sample of two-year colleges differs in terms of their dominant type of organizational culture. The findings demonstrate wide differences in the effectiveness of two-year colleges that exhibit the traits of clan, adhocracy, hierarchy, and market cultures, and the differences are consistent with their conceptual rationale. The research, policy, and practical implications of the findings in terms of our efforts to understand and improve the management and institutional performance of two-year colleges are discussed.Presented at the Association for Institutional Research Annual Forum, Atlanta, Georgia, May 10–13, 1992.  相似文献

Little is known about the use of metaphors in problem solving. In this study, a group of 20 year olds attempted to solve problems with the help of different kinds of metaphors (apt vs. nonapt; remote vs. literal). Different kinds of metaphors were valuable for different aspects of problem solving and for people of differing levels of creativity, but the use of metaphor did not depend on level of intelligence. Literal metaphors did not impede creative thinking, as long as they were apt.

In the Netherlands, Turkish–Dutch children constitute a substantial group of children who learn to speak Dutch at the age of four after they learned to speak Turkish. These children are generally academically less successful. Academic success appears to be affected by both language proficiency and working memory skill. The goal of this study was to investigate the relationship between language skills and working memory in Turkish–Dutch and native-Dutch children from low-income families. The findings revealed reduced Dutch language and Dutch working-memory skills for Turkish–Dutch children compared to native-Dutch children. Working memory in native-Dutch children was unrelated to their language skills, whereas in Turkish–Dutch children strong correlations were found both between Turkish language skills and Turkish working-memory performance and between Dutch language skills and Dutch working-memory performance. Reduced language proficiencies and reduced working-memory skills appear to manifest itself in strong relationships between working memory and language skills in Turkish–Dutch children. The findings seem to indicate that limited verbal working-memory and language deficiencies in bilingual children may have reciprocal effects that strongly warrants adequate language education.  相似文献

Ten rats were trained in a temporal generalization task (the peak procedure) with variations in the time of reinforcement, the intertrial interval, and the mean and variance of the duration of nonfood trials. There were three types of asymmetry in the temporal generalization gradients: positive skew, secondary rise, and positive asymptote. Asymmetrical gradients can occur as a result of asymmetrical sources of variance, multiplicative combinations of symmetrical sources of variance, and effects of anticipation of the end of a trial and the conditions of the next trial. Ten additional rats were trained with a single time of reinforcement, a limited time of reinforcement availability, long and fixed durations of nonfood trials, and a nonresponse requirement for ending a trial. These conditions markedly reduced all asymmetrical sources of variance and led to very symmetrical gradients. These results demonstrate that none of the asymmetrical sources of variance necessarily has a substantial influence on observed temporal generalization gradients.  相似文献
