A 44-item survey instrument was designed to determine secondary students?? views about how useful various specific actions related to reducing global warming might be, their willingness to undertake these various actions and the extent to which these 2 might be linked. The instrument was administered to students in grades 6??C?10 (n?=?768) from 4 large schools in metropolitan Delhi, India in which the teaching language was English. The findings indicated that this cohort of Indian students exhibited high levels of concern about climate change and strong willingness to act against global warming and in favour of the environment. The findings are tentatively compared with those from 2 similar survey studies conducted in Western contexts (Spain and Australia).  相似文献

Witnesses?? event recall and the realism in their evaluation of the correctness of their recall are of great importance in forensic processes. These issues were investigated in the present study by use of calibration methodology. More specifically, we analyzed the effects of two recalls of the same event (repetition) and of probes (non-informative follow-up questions at recall) on 9?C11?year-old children??s and adults?? open free recall and the degree of realism in the participants?? confidence judgments of the correctness of the recall after they had seen a short video clip. The findings were that repetition resulted in more units recalled both for children and for adults, and in that the children showed higher overconfidence compared with one recall, but not the adults. Moreover, when only the statements in the repetition conditions that were recalled twice were included in the analysis, higher confidence was found for the children (independent of an increase in the proportion correct statements of all statements) but not for the adults. Probing increased the number of units recalled for both children and adults, decreased the children??s proportion correct statements but not the adults??, decreased both children??s and adults?? confidence and increased the children??s overconfidence, but not the adults??. Finally, the combination of two recalls and probing disrupted the children??s but not the adults?? metacognitive performance.  相似文献

Geometry and topology are fundamental concepts, which underlie a wide range of fascinating physical phenomena such as topological states of matter and topological defects. In quantum mechanics, the geometry of quantum states is fully captured by the quantum geometric tensor. Using a qubit formed by an NV center in diamond, we perform the first experimental measurement of the complete quantum geometric tensor. Our approach builds on a strong connection between coherent Rabi oscillations upon parametric modulations and the quantum geometry of the underlying states. We then apply our method to a system of two interacting qubits, by exploiting the coupling between the NV center spin and a neighboring 13C nuclear spin. Our results establish coherent dynamical responses as a versatile probe for quantum geometry, and they pave the way for the detection of novel topological phenomena in solid state.  相似文献

Relationships have been found between teacher efficacy and many teaching and learning variables, but few researchers have examined teaching efficacy in physical education. The instrument reported here, the Physical Education Teaching Efficacy Scale, was developed based on the teaching efficacy literature, existing scales, and National Association for Sport and Physical Education's Teacher Education Standards. Students attending 11 institutions who are majoring in regular and alternate physical education teacher education and who are at different stages of preparation (N?=?592) completed the initial survey. Exploratory, followed by confirmatory, factor analysis resulted in a 35-item, 7-factor scale. Factors were Content Knowledge, which were activities one might teach; Applying Scientific Knowledge in Teaching, which reflected academic content; Accommodating Skill Differences; Teaching Students with Special Needs; Instruction, which included management, motivation, and instruction; Using Technology; and Assessment. Results support that the Physical Education Teaching Efficacy Scale addresses many aspects of teaching physical education and meets research criteria for validity and reliability.  相似文献

The goal of the current study was to establish the factor validity of the Questionnaire Assessing School Physical Activity Environment (Robertson-Wilson, Lévesque, & Holden, 2007 Robertson-Wilson, J., Lévesque, L. and Holden, R. R. 2007. Development of a questionnaire assessing school physical activity environment. Measurement in Physical Education and Exercise Science, 11: 93107. [Taylor & Francis Online] [Google Scholar]) using confirmatory factor analysis procedures. Another goal was to establish internal reliability and test–retest reliability. The confirmatory factor analysis results of this study supported a slightly altered version of the Questionnaire Assessing School Physical Activity Environment's school physical activity environment subscale. Internal reliability was adequate, while test–retest reliability was questionable. In brief, the pattern of findings indicated that while the original Questionnaire Assessing School Physical Activity Environment is likely adequate for some research purposes, a slightly modified version (Questionnaire Assessing School Physical Activity Environment-R) was psychometrically stronger. However, given the distinct differences in samples used in the original validation study and the current study, more research on the psychometric properties of the Questionnaire Assessing School Physical Activity Environment is needed to determine if the current results and Robertson-Wilson et al.'s (2007 Robertson-Wilson, J., Lévesque, L. and Holden, R. R. 2007. Development of a questionnaire assessing school physical activity environment. Measurement in Physical Education and Exercise Science, 11: 93107. [Taylor & Francis Online] [Google Scholar]) results are sample specific.  相似文献

Lack of motivation, or amotiation, is emerging as a critical issue in high school physical education. The Amotivation Inventory-Physical Education (Shen, Winger, Li, Sun, & Rukavina, 2010) was developed to measure the multidimensional nature of amotivation construct in physical education. This study was designed to examine the consistency of the metric properties of Amotivation Inventory-Physical Education scores by evaluating their factorial structure for invariance across gender in a sample of 985 urban inner-city high school adolescents. Latent mean invariance was also tested. Results revealed that constraining factor loadings and intercepts in sequential configural, metric, and scalar invariances had no meaningful impact on model fit. However, gender might play a role in the magnitude of factor scores. Findings suggest that the four-factor structure of the Amotivation Inventory-Physical Education is a satisfactory representation of motivational deficits for urban inner-city adolescents and provide significant validity evidence for the scale scores in urban high school settings.  相似文献

Men outperform women in the Mental Rotation Test (MRT) by about one standard deviation. The present study replicated a gender belief account [Moè, A., & Pazzaglia, F. (2006). Following the instructions! Effects of gender beliefs in mental rotation. Learning and Individual Differences, 16, 369–377.] for (part of) this effect. A sample of 300 adults, whose gender beliefs about mental rotation were manipulated experimentally (instructions given: men are better, women are better, or no gender differences exist) had to complete the MRT. Artificially induced gender beliefs affected performance and guessing behavior differently in relation to gender. Women's performance followed the gender belief induction but their guessing behavior remained unaffected. Men's performance, however, remained unaffected but their guessing behavior followed the gender belief induction. These findings suggest that gender beliefs affect men and women differently, and they also suggest that a gender belief account cannot (fully) explain gender differences in mental rotation performance.  相似文献

Many college counseling centers do not collect client data at each session because of perceived burdens. This study explored 55 clients’ and 16 doctoral counselor trainees’ experiences collecting and using data on client distress at each session over the course of counseling at a large public university's counseling center. Results indicated that the majority of both clients and counselors found the process convenient and clinically useful. Findings, clinical implications, and future directions are discussed.  相似文献
