A four-test short form of the WISC-R was developed on the basis of both rational and statistical criteria, using data from the representative standardization sample. The short-form comprised Arithmetic and Vocabulary from the Verbal Scale along with Picture Arrangement and Block Design from the Performance Scale. Various psychometric properties of the abbreviated battery were defined, and indicators of the short form's accuracy in predicting Full-Scale IQ (the standard error of estimate, effectiveness in classifying a child's intelligence level) were provided. A major topic of discussion was the use and abuse of short forms.  相似文献

Developmental trajectories of personal and collective self-concept were examined among American Indian adolescents. Personal self-concept (self-esteem) and collective self-concept (American Indian identity, Euro-American identity, community-mindedness) were assessed 6 times over 3 years in 4 cohorts of adolescents from 3 American Indian cultural groups (N=1,252). An accelerated longitudinal design was used to estimate developmental trajectories from 14 to 19 years; parallel-process and covariate models were used to examine variation in trajectories. Both personal and collective self-concepts were generally positive and showed small gains; they were moderately related to one another and differentially related to cultural group, gender, and perceived social support. The findings highlight the complexity of self-concept for American Indian youth and the significance of both personal and collective identity.  相似文献

We have previously reported in this journal that spatial ability influences academic performance in engineering. We have also reported that spatial ability is trainable, and can be increased through instruction focused on using perception and mental imagery in three-dimensional representation. In this article, we present the results of a longitudinal evaluative study of student difficulties with engineering graphics at our university, involving research over a 24-year period. Prior to our intervention, the first-year engineering graphics course at our university had a failure rate of 36% for all engineering students, and failure rates of 80% for African students studying at our university. In terms of outcomes, our study indicates that changed teaching practices have been associated with increased pass rates, which currently average 88% for all students. There is clear evidence that African students no longer experience major difficulties in passing the course. This can be attributed both to changes in teaching methodology, as well as broader contextual changes occurring in South Africa over the period reviewed.

Despite evidence of increased pass rates, our data suggest that there is a continuing relationship between three-dimensional spatial perception and academic performance in engineering graphics, as well as with aggregated first-year engineering marks. For this reason, many students still require academic support. There is also evidence that female students experience difficulties with engineering graphics due to lack of previous technical experience, and use a variety of strategies to overcome their study problems. The most effective appear to be use of peers and friends, and in particular students who had previously taken the course, as mediators of the course content and materials. Those female students who have not taken technical drawing at school level, and female students who do not network with other engineering students, are those at greatest disadvantage.  相似文献

This qualitative study examined the impact of mentoring relationships upon preservice and inservice teachers' literacy instruction. Twenty-two undergraduate students seeking teacher certification were assigned in pairs to tutor primary school students in a university reading clinic. Eleven classroom teachers seeking reading specialist certification conducted ten mentoring sessions with each pair of preservice teachers. Purposeful sampling was used to select three of the mentoring teams for data analysis. In two out of three teams, results indicated that preservice teachers expanded their instructional strategies as a result of three components of the mentoring relationship: selection of strategies, organization, and non-judgmental support. All inservice teachers reported increased reflection on and adaptation to their instructional strategies. Findings support the conclusion that early mentoring experiences foster growth for both preservice and inservice teachers.  相似文献
