This paper reports a small‐scale longitudinal enquiry into the development of children's ideas on light and vision. It followed the same class from Year 4 (age 9) through to Year 6 (age 11), but the greater part of the information came from Year 5. The data were derived from the children's drawings and written responses, and from small group interviews. Care was taken to ensure that the ideas elicited were the true beliefs of the children. No formal instruction in the subject had been given, nor was any attempted. In the analysis, the children's views have been classified according to a hierarchical set of models, which reflect the strong adherence to an active vision interpretation held by the majority. The extent of progression towards the more scientific view is reported. In the introduction and discussion comparison is made between contemporary non‐scientific conceptions of vision, and the speculations of pre‐scientific philosophers. A final section presents some implications of these findings for teaching the topic. 相似文献

The purpose of this study was to intervene in the process of the Halliwick Method (swimming), in order to improve the method, or some of its aspects, for a sample of 14 individuals with Downs syndrome (aged six to 21 years), using both an individualized educational setting approach and a differentiation of the elements of the Halliwick Method. The pre-intervention phase included medical examination, IQ, measurement of the behaviour according to the Rutter Scale and a Test of Physical Performance for each subject. Next, the subjects were assigned to seven pairs of case studies, where each individual following a Halliwick Methods swimming programme was paired with an individual following a modified swimming programme based on the same method, on physical health variables, IQ, behaviour and motor abilities. The duration of each swimming programme was 24 weeks for each individual, at a frequency of once per week, for 40 minutes. In the light of the findings of this study, further recommendations for the improvement of Halliwick Method procedures were made, common factors that affected the performance of each individual were identified and their relation with performance was explored. 相似文献

This study examined pre-service primary teachers' perspectives on teaching and learning experiences within college-based courses in ‘practical’ subject areas within a teacher education programme. Following three individual lectures (one each in art, music and physical education), pre-service teachers (n=11) participated in focus group interviews sharing their perspectives on the teaching and learning experiences. These data were analysed thematically and supported by teacher educators' (n=3) planning and reflection documentation. Although the problematic nature of the ‘practical’ suggests appeal and peril of the ‘practical’, the important nature of negotiating the ‘practical’ to enhance student learning is apparent. Students emphasised the value of practical engagement and expressed a strong preference for working in groups to create a safe learning environment to develop confidence and competence. These insights suggest key aspects of a pedagogy of teacher education in these ‘practical’ areas. The importance of being aware of and, in some cases, challenging student perspectives on how they learn best in these curricular areas is discussed. 相似文献

Methods for identifying students with learning disabilities continue to be an area of controversy. The present investigation examined the impact of implementing statewide guidelines for the identification of these students. Data were collected from multidisciplinary team reports on 718 students with learning disabilities who were referred and labeled during the 1983-84 school year (before implementation of statewide learning disability guidelines) and 790 students who were identified during 1987-88 (after implementation of the guidelines). The results of the study revealed that the statewide guidelines significantly changed the characteristics of students who were identified. After the implementation of the guidelines, students with much more severe academic problems were identified. These students were much more likely to have a severe discrepancy and be chronically failing in the regular classroom. However, even with explicit, widely accepted guidelines, approximately one third of all students identified in 1987-88 failed to meet the stated criteria for identification. The implications of these findings for professional practice and future research are discussed. 相似文献

This paper considers the history of the emergence and development of cooperative cataloging in Russia and abroad and presents the first projects and programs in the field of cooperative cataloging: CONSER, NACO, BIBCO, and PCC. It elucidates the activity of the OCLC Center and Consortium of European Scientific Libraries, which are the first-rate international cooperative associations, as well as the ARBIKON Association and LIBNET centers which are Russian centers of cooperative cataloging. 相似文献

The concept of “open access” to scientific and teaching information has become one of the specific forms of the worldwide trend towards the formation of global interactive knowledge. This paper presents the basic information on open access (OA) to scientific and teaching information, its current status, financing options, problems and prospects of development, and the participation of Russia in this process. 相似文献

The problem of the construction of the optimal model of the automated control system of a Russian higher-education institution (the ACS of an RHEI) is studied. This term appeared in the 1970s–1980s and served as the beginning of a project that covered more than 50 of the largest higher-education institutions of the country and is also relevant today. Two main approaches to construction of an automated control system of Russian higher-education institutions are specified, viz., the development of a system using its own resources and the use of the product from a third-party developer. Examples of the application of these approaches are given and the structure of the elements (modules) of the systems is described. The necessity to search for the optimal structure of the elements included in the ACS of an RHEI is specified for most educational organizations taking their dimensions into account and their specific sectoral character, as well as the total expenditures for the acquisition (development) and support of the systems. An example of the structure of the optimal model and a third (combined) approach to its construction is given. 相似文献
