Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately. Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception of an image in the eyes. Specializations: science education, students' understandings of phenomena in science. Specializations: cognitive development, evaluation, mathematics and science education. Specializations: mathematics education, students' understanding of chance and data concepts.  相似文献

Instructional technology, especially the use of computers and the Internet has been lagging behind in the German educational system in comparison to other European countries. When this lack was realized in the second half of the 1990s it had quite a “shock-effect” but one of the healthy kind: Since then numerous public and private initiatives have been started to advance the use of technology in schools, higher education, and in vocational training. At the college and university level, there is a trend towards connecting online and offline courses. Also, it was understood that it is not enough to just provide schools and universities with the technology needed but that the introduction of technology has to be accompanied by profound systemic and structural changes. Thus, there is great hope that the use of technology in education will fuel educational innovations at all levels needed for educating and training pupils and students to act as responsible and media-literate citizens in a modern world.  相似文献

The purpose of this study was to determine parents’ and teachers’ perceptions of standards-based and traditional report cards. Participants included 115 parents/guardians of students from a single, midsize school district that had implemented a standards-based report card. During the first two marking periods, all parents/guardians received both a traditional report card in which teachers assigned a single overall grade for each subject and a standards-based report card that included marks for individual standards within subjects. After midyear, parents were asked to complete a survey that asked which form they preferred and the reasons for their preference. Three hundred and eighty three teachers from two nearby midsize school districts considering the adoption of the same standards-based report card completed a similar survey. Parents overwhelmingly preferred the standards-based form. The teachers considering the adoption of a standards based report card were positive overall, but significantly less than the parents who had received them.  相似文献

The main objective of this research paper is to introduce the concept of medical libraries, and to survey the present status of medical libraries in the State of Bahrain in terms of their history, collections, staff, and services. The study gives a general background about the State of Bahrain and its libraries. It also discusses the main problems facing medical libraries in Bahrain. Finally, the study gives some recommendations for developing medical libraries in Bahrain. Personal interviews and documents were used for collecting the information.  相似文献

The purpose of this study was to assess the accuracy of three recommended anthropometric equations for women and then develop an updated prediction equation using dual energy x-ray absorptiometry (DXA). The percentage of body fat (%BF) by anthropometry was significantly correlated (r = .896-.929; p < .01) with DXA, but each equation underestimated %BF (3.2-5.6 %BF; p < .01). The following DXA criterion (DC) equation was created: %BF= -6.40665 + 0.41946(S3SF) - 0.00126(S3SF)2 + 0.12515(hip) + 0.06473 (age); (S3SF = sum of triceps, suprailiac, thigh; hip = circumference in cm; age = years). The predicted residual sum of squares (PRESS) R2 was high (0.86), and the PRESS standard error of estimate (SEE) was low (2.5 %BF) for our sample of 150 women. The DC equation was further crosschecked on a separate sample of women (n = 25) and again showed excellent agreement. The DC equation appears to be a more accurate estimation of %BF in women.  相似文献

Mainstream historiography often turns to Europe's era of empire building to explain the expansion of Western formal education in Africa. Popular accounts suggest that in Africa (1) colonial involvement in education was late and short lived, spanning the early decades of the twentieth century, (2) missionaries were largely responsible for early educational expansion, and (3) education expansion resulted from interdenominational rivalries among missionaries. However, these popular narratives inadequately account for Africans’ own responses to colonial education. This study examines social and cultural shifts in northern Igboland in southeastern Nigeria between 1890 and 1930. It uses colonial archives and oral sources to demonstrate that beyond missionary rivalry, domestic contests converged with the fledgling colonial process to promote English education in northern Igboland. To accomplish this task, the article reviews methodological assumptions responsible for marginal attention to the agency of the colonized in the historiography of Western education in former colonies.  相似文献
