This paper presents a study focusing on differences in Israeli Jewish and Arab chemistry teachers’ beliefs regarding teaching and learning of chemistry in the upper secondary schools. Israel is a country experiencing the problems of diverse cultural orientation of its inhabitants but applying the same educational system to its diverse cultural sectors. Education includes the same curriculum in chemistry for both the Israeli Jewish and Arab cultural sectors as well as final examinations (matriculation) set centrally by the Ministry of Education. Thus, this study can serve as a striking case for other countries facing similar cultural diversity. The study is based on two different instruments that are both qualitative and quantitative in nature. The qualitative data stem from chemistry teachers’ drawings of themselves as teachers in a typical classroom situation accompanied by four open questions. The data analysis follows three qualitative scales: beliefs about classroom organization, beliefs about teaching objectives and epistemological beliefs. A quantitative study gives insights into teachers’ beliefs about what characterizes good education. The main goal of the present paper is to determine whether both groups of chemistry teachers with different sociocultural background in Israel hold different views about education in general and chemistry education in particular. The findings provide evidence that in Israeli chemistry classrooms, the beliefs of Arabic teachers differ from those of the Jewish teachers, although both groups live in the same country and operate the same educational system. 相似文献

Contributing to the recent debate on whether or not explanations ought to be differentiated from arguments, this article argues that the distinction matters to science education. I articulate the distinction in terms of explanations and arguments having to meet different standards of adequacy. Standards of explanatory adequacy are important because they correspond to what counts as a good explanation in a science classroom, whereas a focus on evidence-based argumentation can obscure such standards of what makes an explanation explanatory. I provide further reasons for the relevance of not conflating explanations with arguments (and having standards of explanatory adequacy in view). First, what guides the adoption of the particular standards of explanatory adequacy that are relevant in a scientific case is the explanatory aim pursued in this context. Apart from explanatory aims being an important aspect of the nature of science, including explanatory aims in classroom instruction also promotes students seeing explanations as more than facts, and engages them in developing explanations as responses to interesting explanatory problems. Second, it is of relevance to science curricula that science aims at intervening in natural processes, not only for technological applications, but also as part of experimental discovery. Not any argument enables intervention in nature, as successful intervention specifically presupposes causal explanations. Students can fruitfully explore in the classroom how an explanatory account suggests different options for intervention. 相似文献

Summary Even though the EC-Treaty gives the impression of being unaware of multicultural societies, its regulations can still be interpreted
in such a way as to facilitate and even literally call for a European policy giving due consideration to the phase of adolescence
in multicultural societies.

The inter-rater reliability of university students’ evaluations of teaching quality was examined with cross-classified multilevel models. Students (N = 480) evaluated lectures and seminars over three years with a standardised evaluation questionnaire, yielding 4224 data points. The total variance of these student evaluations was separated into the variance components of courses, teachers, students and the student/teacher interaction. The substantial variance components of teachers and courses suggest reliability. However, a similar proportion of variance was due to students, and the interaction of students and teachers was the strongest source of variance. Students’ individual perceptions of teaching and the fit of these perceptions with the particular teacher greatly influence their evaluations. This casts some doubt on the validity of student evaluations as indicators of teaching quality and suggests that aggregated evaluation scores should be used with caution. 相似文献

This paper describes a case study focusing on the subject matter knowledge, pedagogical content knowledge, and beliefs about science teaching of student teachers in Turkey at the start of their university education. The topic of interest was that of teaching chemical reactions in secondary chemistry education. A written test was developed which used the research literature on potential student misconceptions with regard to different aspects of chemical reactions. Thirty beginning science student teachers were tested, with an additional eight interviews from the student teachers in the same sample. The interviews focused on student teachers’ views about how to best teach chemical reactions in lower secondary chemistry classes. The results revealed deficits in the subject matter knowledge of the student teachers. It also became obvious that the teachers in this sample held very traditional and teacher-centred beliefs when it came to chemistry teaching at the secondary level. Their teaching attitudes were geared mainly towards the acquisition of facts by pupils, and often ignored the development of process-oriented skills. Implications for science teacher education are discussed. 相似文献

Zusammenfassung Die im Rahmen der Modell-basierten Entwicklung eingebetteter Steuerungs- und Regelungssoftware eingesetzten optimierenden
Codegeneratoren müssen einer intensiven Qualit?tssicherung unterzogen werden. Dem Einsatz von Testsuiten kommt dabei eine
zentrale Rolle zu. Der Beitrag beschreibt den Aufbau einer modularen Testsuite für Codegeneratoren und schl?gt einen Testansatz
vor, der eine systematische Prüfung der vom Codegenerator angewendeten Optimierungstechniken erm?glicht.
The optimising code generators employed as part of the model-based development of embedded control software must undergo intensive quality assurance. The use of test suites plays a central role in this process. This article describes the construction of a modular test suite for code generators and proposes a testing approach which makes a systematic test of the optimisations employed by the code generator possible.

ABSTRACT This article explores the ways aesthetic practices and emerging digital technologies are entangled in the practices of industrial designers. Despite the increased interest in the socio-materiality of aesthetic practices, the conception of the materiality and historicity of digital artefacts remains an open issue. It is suggested that the concept of operational form provides an integrative perspective on the technical development and practical enactment of digital technologies. Drawing on an ethnographic case study on the appropriation of a digital sketching application, it is shown how the aesthetic practices and qualities of the digital technologies are reflexively coupled. The study points to the fact that digital technologies are inherently reductive in that they have to abstract from the particularities and richness of concrete aesthetic practices. 相似文献

The modern world can be described as a globalized risk society. It is characterized by increasing complexity, unpredictable consequences of techno-scientific innovations and production, and its environmental consequences. Therefore, chemistry, just like many other knowledge areas, is in an ongoing process of environmentalization. For example, green chemistry has emerged as a new chemical metadiscipline and movement. The philosophy of green chemistry was originally based on a suggestion of twelve principles for environment-friendly chemistry research and production. The present article problematizes limitations in green chemistry when it comes to education. It argues that the philosophy of green chemistry in the context of education needs to be extended with socio-critical perspectives to form educated professionals and citizens who are able to understand the complexity of the world, to make value-based decisions, and to become able to engage more thoroughly in democratic decision-making on sustainability issues. Different versions of sustainability-oriented science/chemistry education are discussed to sharpen a focus on the most complex type, which is Bildung-oriented, focusing emancipation and leading to eco-reflexive education. The term eco-reflexive is used for a problematizing stance towards the modern risk society, an understanding of the complexity of life and society and their interactions, and a responsibility for individual and collective actions towards socio-ecojustice and global sustainability. The philosophical foundation and characteristics of eco-reflexive science education are sketched on in the article. 相似文献

Enrichment programs provide learning opportunities for a broader or deeper examination of curricular or extracurricular topics and are popular in gifted education. Herein, we investigated the effectiveness of a statewide extracurricular enrichment program for gifted elementary school children in Germany. The program implemented a ”grass roots“ strategy by which local units developed and offered the enrichment courses, which spanned a broad array of topics. The courses targeted different outcomes, including students' cognitive abilities, school achievement, interests, creativity, self-control, self-concept, and social competencies. We compared third-grade students attending the enrichment program (N =423) with nonattending third-grade students (N = 2,328) by means of a propensity score analysis. Specifically, we controlled for potential selection effects and estimated the average causal effect of the enrichment program for children attending the program. The findings revealed positive program effects on academic achievement but not on the other targeted outcomes. 相似文献
