A study of primary school children's explanations of a range of phenomena concerning air pressure revealed considerable fluidity in their use of conceptions. A measure of consistency was developed and applied to children's written and oral explanations in a range of contexts. While the results showed a general trend with age toward more abstract, ‘generalizable’ conceptions, the notion of parsimony was found to be problematic on a number of levels. Children do not apply a single conception to a phenomenon, but rather operate with multiple conceptions in their explanations, complicating the whole notion of consistency. Moreover, as they develop and apply more advanced conceptions, children inevitably display temporary reductions in consistency. These findings suggest a rather more complex model of conceptual advance than implied in the literature on ‘conceptual change’. Specializations: children's science explanations, conceptual change, primary science teacher education, physics education.  相似文献

Unattended science and technology exhibits of both static and operational types have been an integral part of museum displays for many years. More recently interactive exhibits in which observers are encouraged to become part of the system of exhibits have become more common. A study was commenced to explore the impact and potential of low cost, unattended, interactive exhibitsset up singly in a normal school classroom without the distractions of a multiplicity of activities as is common in ‘science museums’. Three small groups of Grade 5/6 primary school children interacted with a ‘Falling Towers’ exhibit and their voluntary activities were recorded on videotape for later analysis. Children appeared to state the results of their activity in ways consistent with their expectations rather than with their most recent experience with the exhibit. The responses of girls, boys and mixed groups are reported. Specializations: primary mathematics and science education, teaching strategies. Specializations: science education, students' understandings of phenomena in science.  相似文献

The attitude towards science of first year early childhood education students was explored using an instrument developed for the purpose. The instrument comprises four Likert-type scales, biographical items and two open-ended attitude items. The four scales, characterised as ‘confidence’, ‘enjoyment’, ‘usefulness’ and ‘appropriateness of science for young children’, were supported by varimax factor analysis and had reliabilities from 0.83 to 0.88. Use of the combined scales as a general ‘attitude towards science’ scale was supported by principal components analysis; reliability for the combined scale was 0.94. Comments made in response to the open-ended items supported the validity of the scales. For the student group as a whole, mean scores on all scales were slightly to moderately positive, with the highest mean being for the ‘science for young children’ scale. Students who had studied at least one science subject at Year 12 level had significantly higher scores on all scales than students who had not studied science at senior level.

This paper reports on an investigation into Hong Kong students' comprehension of English non-technical words used in science. The investigation was conducted in a context in which English, a foreign language to students, is the medium of instruction, in that textbooks and examinations are all in English but the classroom language used is mainly Chinese, with frequent Chinese-English code-switching. A total of 4644 Secondary 4, 5 and 6 students participated in the study. Many students did not correctly comprehend a large proportion of the words, confused them with words that were graphologically or phonetically similar, and even took them for their antonyms. Such poor performance raises doubts as to whether the majority of Hong Kong students have attained a ‘threshold level’ of competence in English to benefit from learning science in English. Specializations: physics education, students' alternative conceptions in science, conceptual change, computer-assisted learning in physics.  相似文献

The term ‘concept’ is used in different ways within educational literature and has at least two different, although related, referents in relation to science knowledge, namely, public knowledge and private understandings. A taxonomic structure for ‘science concepts’ (public knowledge) has been developed to provide a rationale for the choice of phenomena to be used in the investigation of students’ ‘concepts’ and also to act as a frame of reference for generating insights about the data to be collected. Furthermore, it may be a useful heuristic to predict other science concepts likely to be highly problematic in school teaching situations and thus worthy of detailed research. The taxonomy, called a ‘Scale of Empirical Distance’ (SED), enables science concepts to be mapped according to their degree of closeness to concrete realities. The scale shows a recognition of the empirical basis of science concepts and the role of human senses in the perception of the material world even though “absolute objectivity of observation is not a possible ideal of science” as Harre (1972) has noted. The scale uses two binary variables, namely, ‘visual’ and ‘tactile’, to generate four categories of science concepts ranging on a continuum from concrete to abstract. Some concepts related to ‘matter’ will be classified and discussed. Specializations: science teacher education, primary science curriculum and methods, students’ personal meanings of phenomena.  相似文献

The widespread public acceptance of many paranormal and pseudoscientific claims should be of some concern to science educators who are striving to produce a scientifically literate community. There is ample evidence to show that students at all levels of our education system believe in aspects of pseudoscience based on claims and assumptions that are in conflict with accumulated scientific knowledge and a rigorous methodology. A survey was designed to assess primary and secondary science teacher-trainees' views. Afterwards 60 students were introduced to the notion of a ‘fair test’ and what constitutes ‘evidence’. Demonstrations of psychic powers were provided and a video shown of professional water-diviners repeatedly failing to locate water under controlled conditions. A re-survey, 3 months later, indicated a rejection of many prior beliefs. However, almost half of the group retained their beliefs in miracles and E.S.P. whilst more than 40% retained their belief in visitors from outer space and that the solar system was created by a supernatural force. Specializations: misconceptions, conceptual change, earth sciences education.  相似文献

One of the requirements of the New Zealand Curriculum Framework (Ministry of Education, 1993a) is that all curricula developed in New Zealand must be gender inclusive. Developers of the recently released science curriculum, and the draft technology curriculum, have responded to this requirement in different ways. In this paper I discuss a theorisation of the term ‘gender inclusive’ within national curriculum development generally, and explore and analyse these different responses within the specific context of the science and technology curriculum developments. Particular emphasis is placed on the historical difference between science education and technology education in New Zealand schools, and on the impact theoretical discourses have on the way in which terms such as ‘gender inclusive curricula’ are conceptualised, and viewed as appropriate, or not, for specific purposes. Specializations: feminist theory, science education, technology education, technology curriculum development.  相似文献

The general aim of our human nutrition project is to develop a health education model grounded in ‘everyday’ or ‘situated’ cognition (Hennessey, 1993). In 1993, we began pilot work to document adult understanding of human nutrition. We used a HyperCard stack as the basis for a series of interviews with 50 adults (25 university students, and 25 adults from offcampus). The interviews were transcribed and analysed using the NUDIST computer program. A summary of the views of these 50 adults on selected aspects of human nutrition is presented in this paper.

This study examines teacher perceptions regarding professional development practices used in a region of the NSW Department of School Education to support the implementation of the K-6 Science and Technology Syllabus. The findings from a survey of 97 teachers indicate that teachers have a preference for ‘traditional’ models of in-service which may not bring about significant changes. Teachers also perceive that change is brought about through the influence of external factors such as in-service and resources which are not directly the responsibillity of individual teachers. This contrasts with the perception that the inability to change is due to internal personal qualities.

Conclusion In the papers presented one can detect a number of major areas of concern. The theorists like Shayer are largely concerned with the development and refinement of frameworks for studying cognitive development. Their ultimate purposes varied from reconstructing the entire field of science education, to accelerating cognitive development, to changing the ‘alternative frameworks’ of children. In essence, they seek totailor the teaching-learning process in accordance with a theoretical blue print. Those who see the problems as more content and context specific would prefer to chip away at particular topics which create teaching difficulties, thereby contributing to the improvement of practice in a more direct, piecemeal fashion. They could perhaps be described astinkers. So we havetinkers andtailors. Thesoldiers amongst us would equip teachers with the weapons needed to attack their own problems directly. They are working away at developing techniques Oh yes, thespies are the moles like me who are concerned with uncovering the secrets of classroom life, with identifying the structures, patterns and processes which characterise classroom interaction, and with the describing and monitoring the ‘theories in action’ and strategies which skilled practitioners have evolved to cope with the problems of promoting cognitive development in classroom settings. The ultimate question then, is what contribution can the tinkers, tailors, soldiers and spies make to science education?  相似文献

Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately. Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception of an image in the eyes.

This research was carried out over a period of ten months with children in Grades 2 and 3 (aged 7 and 8) who were participating in a sequence of technology activities. Since the introduction into Victorian primary schools ofThe Technology Studies Framework P-10 (Crawford, 1988), more teachers are including technology studies in their classrooms and by so doing may assist children's understanding of science concepts. Children are being exposed to science phenomena related to the technology activities and Technology Studies may be a way of providing children with science experiences. ‘Technology Studies’ in this context refers to children carrying out practical problem solving tasks which can be completed without any particular scientific knowledge. Participation in the technology activities may encourage children to become actively involved, thereby facilitating an exploration of the related science concepts. The project identified the importance of challenge in relation to the children's involvement in the technology activities and the conference paper (available from the first author) discusses particular topics in terms of the balance between cognitive/metacognitive and affective influences (Baird et al., 1990) Specializations: science and technology education, interest and attitudinal change. Specialization: technology in the primary school.  相似文献

As there is nothing as practical as a good theory, there is a continuing need in the field of science education enquiry to look for theories which help to interpret the findings about students' alternative frameworks and to inform the design of teaching strategies which relate to a research focus on ‘how the student learns’. The developmental model of cognitive functioning based on the SOLO Taxonomy (Biggs & Collis, 1982) as updated in 1991 (Biggs & Collis, 1991; Collis & Biggs, 1991) is being applied in this way. Questionnaire data from two large studies of science learning of Australian students (conducted by ACER and NBEET) are being re-analysed in terms of the current theory. This paper illustrates the theory and describes a plan of further research. Specializations: science education, students' understandings of phenomena in science. Specializations: cognitive development, evaluation, mathematics and science education. Specializations: mathematics education, students' understanding of chance and data concepts.  相似文献

One of the main goals of science education is the development of scientific investigation skills (Bryce & Robertson, 1985; Woolnough & Allsop, 1985). This paper describes a practical test instrument developed to assess students’ attainment of skills associated with problem analysis and planning experiments, collecting information, organizing and interpreting information, and concluding. During administration of the test, students verbalized their thoughts as they worked on the task and their performance was videotaped for analysis. Preliminary results reveal important areas of student weakness and lead to recommendations for curriculum reform. Specializations: Science teacher education, development of problem-solving expertise, concept development and conceptual change, assessment of laboratory work.

With increasing numbers of students learning science through a second language in many school contexts, there is a need for research to focus on the impact language has on students’ understanding of science concepts. Like other countries, Brunei has adopted a bilingual system of education that incorporates two languages in imparting its curriculum. For the first three years of school, Brunei children are taught in Malay and then for the remainder of their education, instruction is in English. This research is concerned with the influence that this bilingual education system has on children’s learning of science. The purpose was to document the patterns of Brunei students’ developing understandings of the concepts of living and non-living things and examine the impact in the change in language as the medium of instruction. A cross-sectional case study design was used in one primary school. Data collection included an interview (n = 75), which consisted of forced-response and semi-structured interview questions, a categorisation task and classroom observation. Data were analysed quantitatively and qualitatively. The results indicate that the transition from Malay to English as the language of instruction from Primary 4 onwards restricted the students’ ability to express their understandings about living things, to discuss related scientific concepts and to interpret and analyse scientific questions. From a social constructivist perspective these language factors will potentially impact on the students’ cognitive development by limiting the expected growth of the students’ understandings of the concepts of living and non-living things.

Routines are a fundamental aspect of classroom life and much attention in recent years has focused on routines for management. The concept of ‘behaviour settings’ and transitions between them as classroom routines is explained and exemplified. This view of routines provides an explanation for the difficulties faced by relieving teachers and student teachers who enter classrooms at mid year and suggests how new routines for complex science activity may be introduced.

Drawing from social identity theory and its categorization process, the present study crossexamines Japanese students’ contrastively different attitudes toward Asians and European (-looking) people in two different contexts: (1) Japanese students in the overseas English language school context who perceive a sense of solidarity with other Asian, particularly Korean, students in the presence of European students and (2) Japanese students’ yearning for ‘white English’ speakers in Japan and their disregard for Asian and African-looking students on campus. Based on primary data and literature knowledge base, the present study argues that Japanese students’ inclination to make friends with other Asian friends in English speaking countries is context-bound and once they return to their less multicultural home country, their intact yearning for the Imagined West is rekindled. Further discussions are provided for those involved in international education and foreign language education as well as English-as-a-world-language education in postsecondary education.  相似文献

Kuhn (1989) has argued that at the heart of the ability to reason scientifically is the process of differentiating existing mental models (i.e. theory) from new data. In this regard she has proposed a developmental sequence in which, in the early stages, theory and data are fully integrated and are used interchangeably. Later, when theory and data are compatible, they tend to be moulded together as ‘the way things are’, but when they are incompatible conflict is avoided by the use of strategies which bring the two into line: these strategies often include selective attention to the data. Only at the upper levels of this developmental spectrum are theory and data conscientiously differentiated, with each being used to reflect on the other. This paper analyses the responses made by Year 11 students to problems which required them to evaluate a prediction based on some provided data. The problems were set in two contexts, one scientific and one social, and the predictions to be evaluated combined plausibility/implausibility and validity/invalidity. The response patterns were very similar to those described by Kuhn, and the implications of this for teachers, especially those attempting to use conflict based teaching approaches, are developed.

This article is a result of a completed survey of the mainly cognitive science literature on the transferability of those skills which have been described variously as ‘core’, ‘key’, and ‘generic’. The literature reveals that those predominantly cognitive skills which have been studied thoroughly (mainly problem solving) are transferable under certain conditions. These conditions relate particularly to the methods and environment of the learning of these skills. Therefore, there are many implications for the teaching of key skills in higher education, which the article draws out, following a summary of the main findings of the research literature. Learning of principles and concepts facilitates transfer to dissimilar problems, as it creates more flexible mental representations, whereas rote learning of facts discourages transfer. Transfer is fostered when general principles of reasoning are taught together with self-monitoring practices and potential applications in varied contexts. Training in reasoning and critical thinking is only effective for transfer, when abstract principles and rules are coupled with examples. Transfer is promoted when learning takes place in a social context, which fosters generation of principles and explanations. Transfer improves when learning is through co-operative methods, and where there is feedback on performance with training examples. The specificity of the context in which principles are learned reduces their transfer. Transfer is promoted if learners are shown how problems resemble each other, if they are expected to learn to do this themselves, if they are aware of how to apply skills in different contexts, if attention is directed to the underlying goal structure of comparable problems, if examples are varied and are accompanied by rules or principles (especially if discovered by the learners), and if learners’ self-explanations are stimulated. Learning to use meta-cognitive strategies is especially important for transfer.  相似文献
