A study of the development of children's conceptions with respect to projectile motion was carried out in Ukraine and Israel, with the participation of 1017 subjects in grades 3 to 12. The purpose of the research was to investigate the fundamental hypothesis of genetic epistemology with respect to concepts of motion. The fundamental hypothesis states that the development of children's concepts of nature parallel the historical development of the concepts. It was found that the development of children's concepts of motion proceeds by stages, with the concepts at each stage parallel to a corresponding historical stage. A mathematical model was constructed to describe development by stages quantitatively. The theoretical model gave an excellent fit to the empirical data, and this supports the hypothesis of parallelism. The two‐country research made it possible to compare the effects of quite different school science curricula upon the development of children's concepts. 相似文献

Recent evidence indicates that bicultural individuals shift between interpretive frames rooted in different cultures in response to cues encountered in a given situation. The explanation for these shifts has been labeled cultural frame switching. The current research sought to investigate the effect of priming culture among Mexican Americans. Culture was primed by exposing either Mexican or American icons to Mexican Americans prior to the individuals completing an attribution task followed by completing questionnaires assessing emotion. Results revealed that participants primed with American icons reported fewer external attributions and less positive emotion than did participants primed with Mexican icons. 相似文献

This article reports an investigation of some of the skills needed for the critical reading of physics texts. To assess these skills a reading comprehension test was developed that combines features of errordetection and true–false–unreported tests. This test was administered to college students of physics, and the results were analyzed statistically to determine the separability of the skills and their hierarchical ranking. It was found that the skill required to comprehend texts in continuous format is of a higher level than and separable from the skill required to comprehend texts in the form of a separated list of statements. The skill required to discriminate unreported statements from the others (true and false) was found to be of a higher level than and separable from the skills required to make the other discriminations. The relation between the students' reading comprehension skills and their problem-solving ability was also investigated. Students' scores on reading comprehension of texts that require a very low problem-solving ability were found to be uncorrelated to their grades on solving problems that require a very low decoding ability. This implies that the two abilities are independent. 相似文献

The objective of the study was to explore the cognitive profile of creativity in design by applying a new approach to the assessment of creativity based on the theory of meaning (Kreitler & Kreitler). The assessment of meaning enables to identify cognitive processes that characterize an individual as well as those necessary for good performance of some cognitive act, such as creativity. It was hypothesized that creativity in design will include partly cognitive components identified in previous studies of creativity and partly new ones. The participants were 52 students in a school of design, who were administered a designing task and the Meaning Test, assessing a broad range of cognitive processes. The design products were assessed for creativity by three experienced architects. The cognitive processes, differentiating significantly between the students who produced highly creative designs and those who produced less creative ones, were interpreted as constituting the cognitive profile of creativity in design. The obtained profile supported the hypothesis and provided information about the cognitive processes of creativity in design, which may also be used for promoting creativity in design students. 相似文献

A systematic study of children's ideas on motion of macroscopic objects was carried out with the participation of 631 subjects in Grades 2–12 (ages 7–8 through 17–18). An open-ended, four-part questionnaire was administered to the subjects. The responses were categorized according to the level of sophistication of the answer. The results were analyzed using a mathematical model that was first applied to the development of Piagetian stages (Eckstein & Shemesh, 1992, in press). For three of the questions, the responses change as the children mature, and it appears that the children pass through distinct, successive stages with respect to their conceptual understanding of these questions. The mathematical model predicts that the proportion of subjects at each stage is a linear combination of decreasing exponentials. The model fits the experimental data well. Characteristic times for transition between stages were calculated. If teaching strategies to overcome misconceptions are to be effective, then they must be appropriate to the particular misconception prevalent at each stage. 相似文献

This study compared 248 graduating seniors with 301 beginning juniors at 10 bachelor's-level social work programs in the Northeast concerning their knowledge and attitudes regarding working with substance-abusing clients. Graduating seniors demonstrated modestly higher levels of knowledge and only slightly more positive attitudes toward working with this population. In a multivariate analysis, however, having taken a substance abuse course in college or training in settings outside of school improved students' attitudes in this regard. The students' ethnic/racial identity and personal exposure to substance abuse through family, close friends, or self also had a significant impact on their knowledge and attitudes. 相似文献

A theoretical model of cognitive development is applied to the study of the acquisition of formal operational schemata by adolescents. The model predicts that the proportion of adolescents who have not yet acquired the ability to perform a a specific Piagetian-like task is an exponentially decreasing function of age. The model has been used to analyze the data of two large-scale studies performed in the United States and in Israel. The functional dependence upon age was found to be the same in both countries for tasks which are used to assess the following formal operations: proportional reasoning, probabilistic reasoning, correlations, and combinatorial analysis. Different functional dependence was found for tasks assessing conservation, control of variables, and prepositional logic. These results give support to the “unity” hypothesis of cognitive development, that is, the hypothesis that the various schemata of formal thought appear simultaneously. 相似文献

The study deals with the roles and interrelations of the meaning-based assessments of dwellings, pathways and metaphors in design performance. It is grounded in the Meaning Theory [Kreitler, S., and H. Kreitler. 1990. The Cognitive Foundations of Personality Traits. New York: Plenum], which enables identifying the cognitive contents and processes underlying cognitive performance in different domains, thus rendering them more accessible to educational training. The objectives were to identify the components of the meaning profiles of dwellings, pathways, and metaphors as perceived by design students; to analyse their interrelations; and to examine which of the identified components of these constructs serve as best predictors of design performance aided by the use of metaphors. Participants were administered a design task and questionnaires about the Dimensional Profiles of Dwellings, Pathways, and Metaphors, based on the meaning system. Factors based on the factor analyses of the responses to the three questionnaires were used in regression analyses as predictors of the performance score in a design task. The following three factors of the dimensional meaning profiles of metaphors were significant predictors of design performance: sensory, functional, and structural evaluations. Implications for design education are discussed, primarily concerning the important role of metaphor in design problem-solving. 相似文献
