The effects of experience and structured feedback on WISC-R error rates made by student-examiners

The purpose of this study was to determine the effects of experience in the administration and scoring of the WISC-R, coupled with a structured feedback system, on the types and frequencies of examiner errors. Of the five error groupings, the Total Error rate and the Administrative Error rate were both significantly (.001) decreased as a student acquired more experience in administering and scoring the WISC-R, when provided with verbal and written feedback. On the other hand, Response Scoring Errors, Mathematical Errors, and IQ Errors were not significantly reduced by such procedures. Response Scoring Errors and Administrative Errors consistently accounted for over 75% of the Total Error rate.     

Clinically and theoretically derived WISC-R subtest regroupings: Predicting academic achievement in a referral population

Attention continues to be directed toward the WISC-R as a tool for understanding children's learning problems. The formulation of WISC-R subtest regroupings (apart from the traditional Verbal, Performance, and Full Scale IQs, and the empirically derived factor scores) may provide a basis for score interpretation and the generation of hypotheses regarding children's cognitive strengths and weaknesses. The present investigation analyzed the predicitive utility of several WISC-R subtest recategorizations with regard to academic to achievement as measured by the WRAT. The sample consisted of 105 children who had been referred for psychoeducational evaluation because of classroom learning problems. Stepwise regression analyses indicated that many of the regroupings were significant predictors of academic achievement. Generated regression equations are presented.     

运动损伤的心理学

1　根据你们的经验和现有的科学资料信息 ,是否存在与运动损伤有关的重要心理因素或性格类型 ?Gould博士 :很少发现运动员的个性特点与运动损伤的发生有关。然而 ,已经证明心理压力的存在可预示运动损伤发生的增加。从一些生活中的较大事情 (比如失去亲人等 ) ,以及日常小事的争吵中形成的压力 ,与运动损伤风险的增加有关。当然 ,一般情况下 ,心理因素本身并不引起损伤。而当其它不利的身体条件 ,比如肌肉协调性下降 ,或当运动员处在很可能受伤的情况下 ,心理因素就会增加运动损伤的风险。人们认为 ,压力增大运动损伤的风险性 ,是因为压力…     

Cognitive Architecture and Instructional Design

Cognitive load theory has been designed to provide guidelines intended to assist in the presentation of information in a manner that encourages learner activities that optimize intellectual performance. The theory assumes a limited capacity working memory that includes partially independent subcomponents to deal with auditory/verbal material and visual/2- or 3-dimensional information as well as an effectively unlimited long-term memory, holding schemas that vary in their degree of automation. These structures and functions of human cognitive architecture have been used to design a variety of novel instructional procedures based on the assumption that working memory load should be reduced and schema construction encouraged. This paper reviews the theory and the instructional designs generated by it.     

Computer-Mediated Communication Environments in Teacher Education: Computer Conferencing and the Supervision of Student Teachers

The use of computer conferencing environments with student teachers and their supervisors was implemented during teaching practice and evaluated for four teacher education programs. Computer conferencing can be contrasted with the more common supervision methods, such as face-to-face conferences between the student teacher and the cooperating teacher, or between a group of student teachers and their supervisor at the teacher education institute. In our evaluation, we focused on participants' opinions of computer conferencing and their participation, activities and educational outcomes. During their field experiences, student teachers used computer conferencing primarily to exchange emotional support when they recognised similar experiences among their peers. It was less used for reflecting on their teaching and exchanging pedagogical content knowledge, including instructional methods and designs, classroom management strategies, general and instructional theories, and aspects of the teaching profession. This finding led to the conclusion that more attention should be paid to the structure of student teachers' learning environment, because more coaching and instruction of student teachers in their systematic and reflective use of computer conferencing leads to more varied and extensive communication     

Elementary Pre-Service Teacher Perceptions of the Greenhouse Effect

Environmental issues are an important topic both in national news, and in science education. Previous studies revealed that students hold many misconceptions relating to such issues as global warming, ozone depletion, and acid rain. This article expands on earlier work by Boyes et al. to examine pre-service teachers' views about these issues, especially global warming and the related term, the greenhouse effect, and the effect of their views on elementary student performance. Results support the findings of Boyes et al. that elementary education majors hold many misconceptions about these environmental issues, and these can effect their teaching of these topics in elementary classes.
