This paper describes a study conducted in the context of chemistry education reforms in Israel. The study examined a new biochemistry learning unit that was developed to promote in-depth understanding of 3D structures and functions of proteins and nucleic acids. Our goal was to examine whether, and to what extent teaching and learning via model-based learning and animations of biomolecules affect students’ chemical understanding. Applying the mixed methods research paradigm, pre- and post-questionnaires as well as class-observations were employed in the collection, analysis, and interpretation of data. The research population included 175 grade twelve students, divided into three research groups: (a) hands-on exploration of animations, (b) teacher’s demonstrations of animations, (c) traditional learning using textbooks. Findings indicated that the integration of model-based learning and 3D animations enhanced students’ understanding of proteins’ structure and function and their ability to transfer across different levels of chemistry understanding. Findings also indicated that teachers’ demonstrations of animations may enhance students’ ‘knowledge’—a low order thinking skill; however, in order to enhance higher levels of thinking, students should be able to explore 3D animations on their own. Applying constructivist and interpretative analysis of the data, three themes were raised, corresponding to cognitive, affective, and social aspects of learning while exploring web-based models and animations. 相似文献

The contribution of morphological awareness to reading comprehension in Hebrew was studied in 298 second grade students who practiced two types of inflections, plural and possessive. Reading tasks at the beginning and end of the school year indicated that all improved on all tests in that period. Orthographic word recognition and morphological awareness predicted reading comprehension at the end of year. Students with low (LPD) and high (HPD) phonological decoding skills clearly differed qualitatively in reading comprehension. In the HPD students it was predicted by awareness of possessive inflections; in the LPD students it was predicted by orthographic word recognition ability. The results highlight the importance of examining the different components of morphological awareness in readers with different levels of phonological decoding ability. 相似文献

The international,global and intercultural dimensions in schools: an analysis of four internationalised Israeli schools 总被引：1，自引：0，他引：1
Many educational systems worldwide are making substantial efforts to integrate an international dimension into local schools, fostering significant changes in the processes of instruction and learning as well as transformations at pedagogical and organisational levels. In this paper, we analyse data collected in four schools in Israel that the local press and educational authorities have acknowledged as schools that prominently and comprehensively incorporated international, global and intercultural dimensions. We employ a case-study approach based on interviews with principals and teachers; analysis of schools' websites and documents; and on-site observations, in order to analyse the expression of internationalisation, understand who is involved in the implementation process, and stimulate thinking about the broader impact of this process. We find that ideological and pragmatic reasons underlie schools' motivations to internationalise; their population and status comprise major factors in the decision regarding how, where, why, and when to integrate international and intercultural dimensions. The stakeholders interviewed perceive of internationalisation as offering both cosmopolitan capital to the students and a distinctive feature to the school. The schools demonstrate diverse internationalisation patterns that are neither monitored nor guided by any regulatory agency. These findings contribute to the identification of the factors promoting or delaying the internalisation process and to the understanding of the impact of this process on schools. 相似文献

A controversial but increasingly prevalent aspect of media research suggests that the media contributes to the demand for plastic surgery procedures in modern society. This study analyzes the online news content on cosmetic surgery procedures in Korea. Data were collected from ‘Naver,’ the largest Korean portal news archive, from 2007 to 2013. Based on the findings from a quantitative content analysis, the number of articles that pertain to plastic surgery has dramatically increased each year, and since 2007, more than 60% of the news articles portrayed plastic surgery in a positive light. News articles also used strategic patterns to include promotional content. The findings suggest that amid journalism in a highly market-driven environment that struggles to reconcile its role and commercial challenges, plastic surgery, which is a part of the largest advertising sector of online news, has become a commodity. 相似文献
