The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language??often written (as in science texts) or oral (as in the form of teacher and student talk)??is unavoidable in effective teaching and learning of science. Generally however, the role of (instructional) language in quality of learning of school science has remained out of focus in science education research. This has been in spite of findings in empirical research on difficulties science students encounter with words of the instructional language used in science. The findings have suggested that use of (instructional) language in science texts and classrooms can be a major influence on the level of students?? understandings and retention of science concepts. This article reports and discusses findings in an investigation of physics teachers?? approaches to use of and their beliefs about classroom instructional language. Direct classroom observations of, interviews with, as well as content analyses of the participant teachers?? verbatim classroom talk, were used as the methods of data collection. Evidence is presented of participant physics teachers?? lack of explicit awareness of the difficulty, nature, and functional value of different categories of words in the instructional language. In conclusion, the implications of this lack of explicit awareness on the general education (initial and in-service) of school physics teachers are considered. 相似文献

This article investigates the influence of English as the examination language on the solution of physics and science problems by non-native speakers in tertiary engineering education. For that purpose, a statistically significant total number of 96 students in four year groups from freshman to senior level participated in a testing experiment in the Degree Programme of Aviation at the FH JOANNEUM University of Applied Sciences, Graz, Austria. Half of each test group were given a set of 12 physics problems described in German, the other half received the same set of problems described in English. It was the goal to test linguistic reading comprehension necessary for scientific problem solving instead of physics knowledge as such. The results imply that written undergraduate English-medium engineering tests and examinations may not require additional examination time or language-specific aids for students who have reached university-entrance proficiency in English as a foreign language. 相似文献

Content and language integrated learning (CLIL) has been widely implemented in Europe. This article presents a randomised controlled field experiment on the effects of CLIL on students' science learning. Thirty sixth-grade intermediate-track German secondary-school classes (722 students) were randomly assigned to learn (5 lessons, 90 min each) a physics topic taught either in German or in English and German. We expected that the monolingually taught students would outperform the bilingually taught ones immediately after the intervention. For the follow-up test 6 weeks later, the same or smaller differences between the groups were expected due to the potential for a deeper processing of the subject matter in the bilingual condition. The results showed that the bilingually educated students' learning gains were smaller than the monolingually educated ones' immediately after the intervention (d = −0.21) and at follow-up (d = −0.23). The expectation of more sustainable processing was not supported. 相似文献
