Analogy,Metaconceptual Awareness and Conceptual Change: a classroom study

This qualitative study aimed at exploring whether students’ successful use of analogy in learning curriculum complex science concepts was related: (a) to the level of their understanding of a specific analogy and (b) to their metacognitive awareness of how the analogy was to be used and of the changes produced in their own conceptual structures. In implementing a biological curriculum unit, students’ prior knowledge has been taken into account in order to examine its conceptual growth and change via a not completely introduced analogy to 15 fifth graders as they were engaged in understanding the ways in which the new concepts (on photosynthesis) were similar to a familiar source (making a cake). Qualitative data present the children's mapping processes in elaborating the analogy and their metacognitive awareness of the meaning and purpose of the analogy itself, and their personal use of the analogy in changing initial conceptions. As hypothesised, the results showed a high positive correlation among the level of conceptual understanding of the new science topic, the level of understanding of the analogy, and the level of effective use of the analogy in integrating the new information into the pre‐existing conceptual structures. Key implications on the use of analogy for conceptual change in the classroom are outlined.     

What is the students’ interest in biology after the biology curriculum modification?

Decreasing interest in Science among students, confirmed by several investigations, calls for the need to revise the contents of the curricula for Science subjects, including Biology. Modern Biology curricula should not only contain key biological concepts but also provide a teacher with sufficient space to develop students’ competencies of scientific work and positive attitudes to Science. When preparing the curriculum, it is necessary to consider also students’ interest in selected curriculum topics and their benefit for everyday life. The objective of our research was to identify whether the performed transformation of the Biology curriculum for elementary schools increased the students’ interest in Biology and the contents thereof. We were also investigating students’ preferences in their interest in Biology topics and their interest in selected teaching methods and approaches. Our research confirmed the positive interest in Biology among majority of students who prefer direct, active participation in the process of knowledge acquisition through the study and exploration of living organisms as well as by the execution and assessment of practicals and experiments.     

Teaching thinking — A focus for science teaching?

Conclusion The studies briefly reported in this paper reveal the enormous potential in the direct teaching of thinking for improving the thinking skills of students. Science education could be a powerful vehicle for such an approach. In the short term this could be achieved by incorporating an existing program such as CoRT as a core science curriculum element. The detailed study and reporting of such implementation efforts is important in suggesting ways forward. In the longer term, the design of new science curricula which have as a major focus the direct development of thinking skills should be a priority.     

A framework for implementing and teaching the social and ethical impact of computing

This article describes the work of Project ImpactCS, which was initiated to define the core content and pedagogical objectives for integrating social impact and ethics into the computer science (CS) curriculum. Over a three year period the project will address three major problems that hamper the implementation of across-the-board curriculum change: the lack of a well-specified definition of what the core content and learning objectives should include, the lack of a strategy for adapting and adopting existing materials that address the core topics into the existing CS curriculum, and the lack of awareness and expertise on the part of most CS faculties regarding the need and methodology for presenting such material in their courses. This report provides the conceptual frame-work and describes the learning objectives, called knowledge units, for defining a new content area in the computer science curriculum. It also discusses strategies and innovative pedagogical techniques for implementing the knowledge units into the curriculum.     

Between two science curricula: the influence of international surveys on the Israeli science curriculum

International surveys have served as agents of change for the introduction of reforms in curricula worldwide. The Israeli Ministry of Education set a goal of raising Israel's ranking in international surveys so that Israel will be among the 10 leading countries in the Program for International Student Assessment and Trends in International Mathematics and Science Study (TIMSS). The Ministry of Education therefore acted to reduce the gap between the intended and the attained science curriculum by intervening on two curricular levels: the intended and the implemented. Over the years, documents that contributed to the adoption of contents and skills from the international surveys were added to the science curriculum, until the publication of the new science curriculum. The intervention was successful and in TIMSS 2011, Israel ranked 13 out of the 42 participating countries. The present research examines the influence of international surveys on science education in Israel, over the course of time (1996–2011). Analysis of documents accompanying the curriculum shows a clear message that international surveys are standards that should be used for teaching, and every additional document closes the gap between the science curriculum and the international surveys.     

Progression in school science curriculum: A rational prospect or a chimera?

Science in schooling has for the first time been recently considered as a verified whole for the 10 or 12 of its compulsory years, rather than for a limited sector of schooling or for a particular group of students. This has also been occurring as part of a wider review and plan for the whole curriculum of schooling. A framework has been provided consisting of a matrix of strands of intended content for learning across a number of levels approximating the years of schooling. There is a sense and expectation of continuous progression in the learning of science. Earlier notions of progression in science curricula are explored and compared with what has now appeared in the national curricula in England and Wales, New Zealand and Australia. The notions of curriculum opportunity and curriculum purpose for science education are introduced as factors that would lead to a shift in the sense of progression from a focus on Science itself to an emphasis on the learners' changing need of Science as they progress through the years of schooling.

学科和课程分化与综合的辩证法

科学和学科是课程的基础,科学和学科内容的发展趋势必然影响课程教学内容的发展走势。科学、学科和课程的分化与综合是辩证的。分化是综合的基础,综合是分化的结果。没有分化就没有综合,只是混沌。在分化基础上的综合和在综合基础上的分化既是近现代科学、学科和课程发展的基本趋势和规律,也应该是未来科学发展、学科建设和课程改革的基本依据。     

Students’ Knowledge of Nuclear Science and Its Connection with Civic Scientific Literacy in Two European Contexts: The Case of Newspaper Articles

Nuclear science has uses and applications that are relevant and crucial for world peace and sustainable development, so knowledge of its basic concepts and topics should constitute an integral part of civic scientific literacy. We have used two newspaper articles that deal with uses of nuclear science that are directly relevant to life, society, economy, and international politics. One article discusses a new thermonuclear reactor, and the second one is about depleted uranium and its danger for health. 189 first-year undergraduate physics and primary education Greek students were given one of the two articles each, and asked to answer a number of accompanying questions dealing with knowledge that is part of the Greek high school curriculum. The study was repeated with 272 first-year undergraduate physics, physics education, science education, and primary education Turkish students. Acceptable or partially acceptable answers were provided on average by around 20 % of Greek and 11 % of Turkish students, while a large proportion (on the average, around 50 % of Greek and 27 % of Turkish students) abstained from answering the questions. These findings are disappointing, but should be seen in the light of the limited or no coverage of the relevant learning material in the Greek and the Turkish high-school programs. Student conceptual difficulties, misconceptions and implications for research and high school curricula are discussed.     

Ten Years of CERI

Summaries

English

The purpose of this study was to determine whether the different value positions claimed by Macdonald to be inherent in his three curriculum development models resulted in differences in the content of science curricula and/or the organization of such content. Information on this subject was obtained from a sample of 90 randomly‐chosen science teachers vvho examined junior high school physical science curricula, then completed a questionnaire used as a measuring instrument. This instrument was based on established criteria for selecting and organizing content for a curriculum. From the results obtained, it was concluded that significant differences in content as well as in content organization did indeed exist in the science curricula representative of Macdonald's three models. Moreover, it was found that content representative of specifie groups of selection criteria such as discipline‐oriented, societal needs, and student needs was responsible for the differentiation in the content among the models. Thus, the findings supported Macdonald's contentions. This information should be useful in future science curriculum development.     

An assessment of how scientific literacy-related aims are actualised in the National Primary Science curricula in China and Finland

This research compared how the scientific literacy-related goals of the current Chinese and Finnish national science curricula at primary school level are actualised using a revised Programme for International Student Assessment (PISA) scientific literacy framework in the content analysis of the curricula. The content of the curricula focuses principally on knowledge, followed by competencies and attitudes, respectively. The learning context was seen to be thoroughly integrated with the content in both countries. However, the curricula are written in different ways. Generally, the literacy objectives for both curricula are based on scientific knowledge (Vision I) and the application of knowledge-based skills in situations (Vision II). However, they are characterised by implicit views that derive from the pursuit of the value-driven transformation of individuals and society achieved through science education (Vision III). The Chinese curriculum appears to favour the Anglo-American curriculum tradition, whereas the Finnish curriculum appears to be more attached to the Bildung-Didaktik tradition in terms of core tasks and the specification of objectives. The recommendation is that Vision III should be included in the science curricula, and should explicitly relate to social and scientific topics with a view to furthering a scientifically literate public.     

When technology,science and culture meet: insights from ancient Chinese technology

This paper draws together two important agendas in science education. The first is making science education more inclusive such that students from non-Western or indigenous cultures can benefit from culturally relevant curricula. The second is integrating technology into the curriculum under the umbrella of Science–Technology–Society (STS) education to embrace the social aspects of science, with technology serving as a bridge. The advancement of the first agenda is hindered by the pursuance by both Western and non-Western societies of narrow cultural and practical goals without considering the development of science and technology from a cross-cultural perspective. The second agenda is limited by the misconception that technology is applied science, leading to the exclusion from STS discussions of pre-science or indigenous technologies developed by non-Western cultures. Through selected case studies of the evolution of Chinese traditional technologies and their interaction with science, this paper offers a perspective from the Far East, and argues for situating culturally responsive science education in broader historical and cross-cultural contexts to acknowledge the multi-cultural contributions to science and technology. A form of cross-cultural STS education is advanced, encompassing the cultural basis of technological developments, technology diffusion, interactions of traditional technology with science, and the potential development of traditional or indigenous technologies. This approach provides a bridge between the existing universal science education paradigm promoted in the West and the different forms of multi-cultural education advocated by indigenous science educators. To translate theory into practice, a conceptual framework is proposed in which the essential transdisciplinary knowledge base, curricular goals, and pedagogical approaches are embedded.     

The Intellectual Demands and Coherency of Topics of Reformed Primary Science Curricula from Three East-Asian Regions

The intended curriculum is arguably one of the most important components within any national educational system although those in primary science have not been subject to extensive research scrutiny. Based on reformed primary science curricula from Hong Kong, mainland China, and Taiwan, we compared them on two key features: (1) levels of knowledge and cognitive processes from their learning outcomes, and (2) coherency of topics that influence the ease, meaningfulness, and quality of learning in the subject. In the former, we coded their intellectual demands (i.e., what learners must know and do) using revised Bloom’s taxonomy while for the latter, we investigated the coverage, focus, sequence, and emphasis of topics across grades. We found that curricula from Hong Kong and mainland China generally focused on the first two levels of knowledge domains and cognitive processes while Taiwanese learning outcomes were predominantly coded as Apply. Different aspects of coherency in the intended curriculum revealed which topics were covered, their focus, and sequencing across grade divisions as well as their emphasis of topics. Our empirical research therefore adds to the small number of comparative studies in primary science curricula. It can also practically assist policy- and curriculum-making in these regions as they seek to understand and develop quality curricula in primary science.

     

Science Trainee Teachers' Pedagogical Content Knowledge and its Influence on Physics Teaching

This study examined Malaysian science teachers' pedagogical content knowledge (PCK) of selected physics concepts. The two components of PCK investigated were (i) knowledge of students' understanding, conceptions and misconceptions of topics, and (ii) knowledge of strategies and representations for teaching particular topics. The participants were 12 trainee teachers from various academic science backgrounds attending a one-year postgraduate teacher-training course. They were interviewed on selected basic concepts in physics that are found in the Malaysian Integrated Science curriculum for lower secondary level. The findings showed that trainee teachers' PCK for promoting conceptual understanding is limited. They lacked the ability to transform their understanding of basic concepts in physics required to teach lower secondary school science pupils. The trainees' level of content knowledge affected their awareness of pupils' likely misconceptions. Consequently, the trainees were unable to employ the appropriate teaching strategies required to explain the scientific ideas. This study provides some pedagogical implications for the training of science teachers.     

One Brief,Shining Moment? The Impact of Neo‐liberalism on Science Curriculum in the Compulsory Years of Schooling

The past 20 years or so have seen ongoing concern for the nature of science education in the Anglophone developed world. A particular focus of this concern has been the need to find new ways to frame science curricula that will engage students, yet it is proving difficult to achieve this goal. In this article I argue that the impact on science curriculum of a societal shift to neo‐liberalism and an attendant policy shift to outcomes‐based education should be explicitly acknowledged; further, that the forms of curriculum that emerge from neo‐liberalism are unlikely to provide the engaging and inclusive science education needed today. To illustrate the impact of the neo‐liberal societal shift on science curriculum I compare an exemplary, inclusive and innovative science curriculum document from the 1980s with its outcomes‐based successor from the 1990s. I show that in this case the shift to the outcomes‐based form significantly restricted the possibilities for framing science education to respond to the local community, restricting a vision of science as a social institution; further, it framed each learner as an individual to the exclusion of community while reducing options for framing learning to meet individual needs. I argue that it is important for the future disciplinary well‐being of science, and for the well‐being of society on the whole, that both science and its scientists be seen as socially located. Science curriculum documents must initiate and support this perspective.     

Marginalization of Socioscientific Material in Science–Technology–Society Science Curricula: Some Implications for Gender Inclusivity and Curriculum Reform

Science education reformers have argued that presenting science in the abstract is neither motivating nor inclusive of the majority of students. Science–technology–society (STS) curricula that give science an accessible social context have developed in response, but controversy surrounds the extent to which students should be introduced to socioscientific debate. Using material from a case study of Salters' Advanced Chemistry in the United Kingdom, this article demonstrates how socioscientific material is marginalized through the structures and language of syllabus texts and through classroom practices. This means students are unlikely to engage with socioscientific aspects in their course. Socioscientific content is gendered through association with social concerns and epistemological uncertainty, and because gender is asymmetric, socioscience is devalued with respect to the masculinity of abstract science. Teachers fear that extensive coverage of socioscience devalues the curriculum, alienates traditional science students and jeopardizes their own status as gatekeepers of scientific knowledge. Thus, although STS curricula such as Salters' offer potential for making science more accessible, the article concludes that greater awareness of, and challenges to, gender binaries could result in more effective STS curriculum reform. © 2000 John Wiley & Sons, Inc.

RETHINKING THE HISTORY OF INCLUSION OF IKS IN SCHOOL CURRICULA: ENDEAVORING TO LEGITIMATE THE SUBJECT

Much has been said and written about indigenous knowledge systems (IKS) or, as it is also termed, traditional ecological knowledge. My paper does not intend to discuss how it should be termed, although this is also an important issue as the way we name it frames the possibilities we open for this kind of knowledge. The paper rather looks historically at indigenous knowledge inclusion in school curricula, taking as an example the practice in Mozambique. So far, many strategies in so-called culturally inclusive science curricula tend to take students along the pathway of cultural assimilation by integrating IKS into World Modern Science topics. IKS is therefore taken as an instrument for serving the goals of World Modern Science. I argue that we need to find legitimated theories to integrate IKS in order to counteract the practice of teaching IKS in science classrooms detached from its own sociocultural context.     

Cognitive and metacognitive aspects in conceptual change by analogy

This study is a qualitative investigation on the teaching-learning by analogy of complex curriculum concepts in natural and relevant environments, such as classrooms, to improve the ecological validity of the research itself. It aimed at exploring whether students' successful use of analogy in learning science was related a) to the level of their understanding of a specific analogy and b) to their metacognitive awareness of how the analogy was to be used and of the changes produced in their own conceptual structures. During the implementation of a biological curriculum unit, sixty 5th graders were engaged in understanding the ways in which the new concepts (concerning the human circulatory system) were similar to a familiar source (the mail delivery system) by detecting all the relations between the two systems and mapping the relevant information from the source to the target. Learners' preexisting mental models have been taken into account in order to examine their conceptual growth and change via the analogy. Qualitative data are presented for the analysis of elicited and spontaneous analogical inferences, based on structural and semantic similarities, as well as of the identification of where the analogy breaks down. Moreover, qualitative data also concern children's metacognitive awareness of the meaning and the purpose of the analogy, and their personal use of the analogy in changing initial conceptions. As hypothesized, results showed a high correlation between level of conceptual understanding of the new science topic, level of understanding of the analogy itself, and the effective use of the analogy in integrating the new information into the pre-existing conceptual structures. Some implications on the use of analogy for conceptual change are considered from an educational standpoint.     

The effect of teachers' sociological understanding of science (SUS) on curricular innovation

Science education reform initiatives advocate incorporating more accurate portrayals of science in the high school classroom that attend to science in its larger social context. However, conveying such understandings will require teachers to possess new knowledge about how science is practised. This paper reports research that investigated the effect of teachers' sociological understanding of science (SUS) on their design and implementation of curriculum innovations. It concludes that teachers' SUS level strongly influences their ability to innovate; knowledge about science is necessary, but not sufficient, for sociologically informed curricula.
