The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals. Here we report on a study in which teachers, as part of their professional development, were involved in defining the term ‘chemical literacy’; they discussed the need for it, and suggested educational experiences that are necessary in order to attain it. The programme was conducted as part of a reform in the content, as well as in the pedagogy, of chemistry education in Israel. The collected data provide some insights regarding the process by which the teachers’ perception of ‘chemical literacy’ developed and the way actual school practice influences teachers’ perception of ‘chemical literacy’.  相似文献

Providing learning environments that are motivating for female students and male students alike is a challenge for science educators. This overview of the research conducted in science museums provides initial insights into informal educational settings that allow female visitors to have experiences which foster development of science interest and learning. The discussion of the influence of gender on learning experiences in informal science environments raises questions and calls for further research and more comprehensive reporting of research results. Findings related to gender‐equitable learning in settings such as science museums would be beneficial and extend the present knowledge base in science education.  相似文献

Given the progressive loss of influence for the school relative to television in youngsters’ everyday lives, this article describes the procedure and the results of including cartoons in the physics curriculum in secondary education. Work was carried out intensively with a small group of pupils and sporadically with a larger group. In the first case, cartoons were used for identifying and discussing fictitious phenomena, problem‐solving, and assessment of the learning. In the second case, for identifying and discussing fictitious phenomena, a quasi‐experimental research design was followed. The results back the use of this didactic tool as an element for motivating and invigorating the classroom, for identifying the pupils’ alternative ideas and the assessment of their learning, as well as for a more critical way of watching television.  相似文献

The main purpose of this study was to examine the structural relationships between scientific epistemological views (SEVs) and information commitments (ICs) of high school students in Taiwan. Data were collected from 486 Taiwanese high school students via two self‐reporting instruments: one was the SEV questionnaire, including five scales for representing students’ views toward scientific knowledge; and the other was the ICs survey, involving six scales for exploring their evaluative standards and searching strategies of online science information. Structural equation modelling analysis was used to examine the relationships between the aspects of SEVs and ICs. The results of the measurement model confirmed that both the SEVs and ICs instruments had highly satisfactory validity and reliability. The structural equation modelling analysis further indicated that students’ SEVs guided their evaluative standards and searching strategy when dealing with Web‐based science information. For example, students who viewed scientific knowledge as more changeable and tentative significantly tended to adopt a more sophisticated evaluative standard, such as carefully inspecting the content of web sites for judging the usefulness. The findings in general suggested that students with more constructivist‐oriented SEVs might develop more advanced standards and searching strategy toward online scientific information to derive great benefit from Web‐based environments. Consequently, the role of SEVs should be highlighted as increasingly metacognitive engagement with online science information.  相似文献

This paper reports a cross‐sectional study of Taiwanese physics students’ understanding of subatomic phenomena that are explained by quantum mechanics. The study uses students’ explanations of their answers to items in a questionnaire as a proxy for students’ thinking. The variation in students’ explanations is discussed as is the development in the way in which students link different concepts. A discussion of the source of students’ ideas turns to the way schema contain mental models that derive from sensori‐experiences. The principal recommendation for teaching is the need to include practical activities on a range of precursor phenomena so as to extend the students repertoires of mental models. This advice is different from that given in previous studies.  相似文献

This paper reports the relationship between four English primary teachers’ understanding of the nature of science and their practice. Action research was included as a major part of the research design in order to explore the dialectical interplay between various factors at work in the teachers’ practice. The influences of both tacit and espoused understandings of the nature of science were considered alongside the teachers’ beliefs about education, teaching, and learning. These beliefs were found to be the determining factor in the teachers’ decisions about classroom strategies. In arguing for a dialectical perspective on teachers’ practice, the research suggests that teachers’ espoused understanding of the nature of science may also be at least partially formed by the influence of these beliefs, raising the possibility that influence may run from teaching to theoretical understanding and not the other way round.  相似文献

In this article we discuss the theoretical and practical rationale for establishing a collaborative science practicum project and report on the findings of the first two years. The project was designed to strengthen the communication links among the school‐based educators, the pre‐service teachers, and the university‐based educators, in order to address the seemingly intractable problems associated with initiating new science teachers into the varied social practices of the teaching profession. Our findings are organized and discussed in the form of three dilemmas (Cuban 1992). These dilemmas are associated with the difficulties the pre‐service teachers had in connecting the propositional knowledge presented in the university setting with the procedural knowledge required in the school setting, and the lack of familiarity by the university and school‐based educators of each other's practice setting. We describe results that resonate with similar issues reported in other collaborative projects, and propose an alternative approach for preparing science teachers. This approach is based on conceptualizing learning to teach as a cognitive apprenticeship (Hennessy 1993) which prepares pre‐service teachers to enter the ‘community of practice’ called teaching. We argue that the success of such an approach requires the development of a collaborative community in which all participants engage in meaningful and supportive discourse concerning what, when and how science is taught in the classroom.  相似文献

Based on the teachers’ lectures and evaluations we elaborate on a model of the aspects of learning. Inside the framework of this model three ways for solving a given problem relating to the previous teaching are presented.

We describe and analyse a method which is useful in selecting an evaluation task adapted to intended objectives, helps in the interpretation of the students’ performances and acts as a guide to the possible inferences about what the students acquire.  相似文献

Due to the implementation of a 9‐year integrated curriculum scheme in Taiwan, research on team teaching and web‐based technology appears to be urgent. The purpose of this study was incorporated web‐assisted learning with team teaching in seventh‐grade science classes. The specific research question concerned student performance and attitudes about the teaching method. Two certified science teachers and four classes of the seventh graders participated in this study. It used a mixed methods design, incorporating both quantitative and qualitative techniques. The main data included students’ scores, questionnaires, teachers’ self‐reflections, and the researcher’s interviews with teachers. The results showed that the average final examination scores of students experiencing the experimental teaching method were higher than that of those receiving traditional teaching. The two teaching methods showed significant difference in respect of students’ achievement. The research had limitations because of students’ abilities of data collection, computer use, and discussion, but more than one‐half of the students preferred the experimental method to traditional teaching. However, team teachers would encounter the problems of technology ability, time constraints, and entrance examination pressure.  相似文献

The development of a science education that includes a focus upon the nature of science suggests the need for “pedagogic tools” that can be used to engage children with the procedural understandings that are central to the scientific approach to enquiry. This paper reports on a collaborative action research project that focused on the use of secondary data as just such a “tool” for stimulating engagement with procedural understandings among primary school children. It argues that the comparative analysis of secondary and investigative data can provide a basis for such engagement. However, such comparative analysis will only mirror the collaborative nature of the scientific enterprise where children have guided opportunities to discuss their understanding of the issues revealed by the comparisons. The research suggests that children work best with this data if the scientific approach to enquiry is contextualized through connection with the knowledge claims made in science.  相似文献
