The study investigated elementary school pupils' ideas concerning the concept of electricity and the effect of school instruction on the pupil's views. Pupils of different cultural backgrounds were assessed to ascertain their knowledge in four areas: Relation of certain natural phenomena to electricity; Mental models (images) of direct current in a circuit; Images possessed regarding electricity and electric current. Pupils' ideas were investigated before and after instruction, thus providing information about the effect of instruction on the views of pupils. In construct to the previous findings, certain phenomena (lightning and thunder among them) were related by the pupils to electricity even before those were taught. Evidently, the instruction changed the mental models and images of electricity and electric current. 相似文献

This study examined relations between behavioral inhibition (BI) assessed in toddlerhood (n = 268) and attention biases (AB) to threat and positive faces and maternal‐reported anxiety assessed when children were 5‐ and 7‐year‐old. Results revealed that BI predicted anxiety at age 7 in children with AB toward threat, away from positive, or with no bias, at age 7; BI did not predict anxiety for children displaying AB away from threat or toward positive. Five‐year AB did not moderate the link between BI and 7‐year anxiety. No direct association between AB and BI or anxiety was detected; moreover, children did not show stable AB across development. These findings extend our understanding of the developmental links among BI, AB, and anxiety. 相似文献

Children's ideas about action at a distance are analysed according to the commonsense theory. These ideas can be organized around three presuppositions which express concrete realizations of the abstract idea of interaction at a distance. The presuppositions are concerned with the uniqueness of earth, the need for connection between objects interacting at a distance, and how various forces support and focus each other. These ideas do not form a self‐consistent set of axioms to be applied coherently, but rather form a guiding framework. The chosen presuppositions are context dependent and related to the different environments of earth, a satellite, the moon and outer space. Support is preferred over connection. The relevance of these findings for instruction are discussed. 相似文献

Summaries English In this article, the authors reflect on the development and implementation of the Israel Elementary Science Project (MATAL). The MATAL project, initially established in 1968, used British and American programmes as its foundation, but so modified them that they became applicable to the needs of less developed countries. The authors describe the structure and content of their project, as well as their work in teacher training and the development of ancillary and enrichment programmes. It is hoped that the Israeli experience in developing an elementary school science curriculum will be of interest and potential benefit to curriculum workers in other countries also. 相似文献

The image of ‘the scientist’ and its effect on the willingness to be a scientist and to follow a career in science were investigated in two different cultural populations of elementary and junior high school pupils in Israel: Hebrew‐speaking (secular) pupils (N = 390) and Arabic‐speaking Bedouin pupils (N = 185). Five different tools were employed in our investigation (naming scientists, pictorial representation of the scientist (‘Draw‐a‐Scientist‐Test’), statements regarding the characteristics of the scientist, reasons for wanting/not wanting or being able/being unable to be scientists, and sources of knowledge regarding the scientist’s image). The image held by Hebrew pupils was similar to those held by western pupils found in previous research, but some details were more elaborate (due to the fact that many different tools were employed here). However, the image held by the Arabic pupils differed from that found in previous research. This image had a strong ethnical trend, with Golden Age Muslim scientists’ names dominating name lists, and drawings of traditional Muslim figures. Another image found in their drawings was of a scientist admired as a teacher, emphasising the Bedouin school’s formal culture. The theory of modernity will be a useful analytical tool to judge the results of the investigation, whether the population is supposed to be (or is close to) a modern population and whether it does not, definitely, fall under this definition (see Methods and Discussion). 相似文献
