In response to the authors, I demonstrate how threshold concepts offer a means to both contextualise teaching and learning of quantum physics and help transform students into the culture of physics, and as a way to identify particularly troublesome concepts within quantum physics. By drawing parallels from my own doctoral research in another area of contemporary physics—special relativity—I highlight concepts that require an ontological change, namely a shift beyond the reality of everyday Newtonian experience such as time dilation and length contraction, as being troublesome concepts that can present barriers to learning with students often asking “is it real?”. Similarly, the domain of quantum physics requires students to move beyond “common sense” perception as it brings into sharp focus the difference between what is experienced via the sense perceptions and the mental abstraction of phenomena. And it’s this issue that highlights the important role imagery and creativity have both in quantum physics and in the evolution of physics more generally, and lies in stark contrast to the apparent mathematical focus and lack of opportunity for students to explore ontological issues evident in the authors’ research. By reflecting on the authors’ observations of a focus on mathematical formalisms and problem solving at the expense of alternative approaches, I explore the dialectic between Heisenberg’s highly mathematical approach and Schrödinger’s mechanical wave view of the atom, together with its conceptual imagery, at the heart of the evolution of quantum mechanics. In turn, I highlight the significance of imagery, imagination and intuition in quantum physics, together with the importance of adopting an epistemological pluralism—multiple ways of knowing and thinking—in physics education. Again drawing parallels with the authors’ work and my own, I identify the role thought experiments have in both quantum physics education and in physics more generally. By introducing the notion of play, I advocate adopting and celebrating multiple approaches of teaching and learning, including thought experiments, play, dialogue and a more conceptual approach inclusive of multiple forms of representation, that complements the current instructional, mathematical approach so as to provide better balance to learning, teaching and the curriculum. 相似文献

We describe the main principles of the framework theory approach to conceptual change and briefly report on the results of a text comprehension study that investigated some of the hypotheses that derive from it. We claim that children construct a naive physics which is based on observation in the context of lay culture and which forms a relatively coherent conceptual system—i.e., a framework theory—that can be used as a basis for explanation and prediction of everyday phenomena. Learning science requires fundamental ontological, epistemological, and representational changes in naive physics. These conceptual changes take a long time to be achieved, giving rise to fragmentation and synthetic conceptions. We also argue that both fragmentation and synthetic conceptions can be explained to result from learners’ attempts assimilate scientific information into their existing but incompatible naive physics. 相似文献

Historical excurse was suggested as a beneficial form of using the history and philosophy of science in the modules of learning materials developed within the History and Philosophy in Science Teaching project. The paper briefly describes the theoretical framework of the produced modules, addressing ontological and epistemological aspects of historical changes in physics knowledge with regard to several particular concepts relevant to school course of physics. It is argued that such excurses create Cultural Content Knowledge which improves the Pedagogical Content Knowledge in teachers and are appropriate to facilitate the meaningful learning by students. The modules illustrate the new aspect of the scientific knowledge not sufficiently addressed in the current science educational discourse??the constructive diachronic discourse that took place in the history. Historical excurse makes explicit the paradigmatic conceptual changes in physics knowledge and thus creates the space of learning in which the ??correct?? knowledge (type I) emerges in a discourse with the alternates (type II knowledge). Some of the previous conceptions show certain similarity to students?? misconceptions which further motivates essential use of both types of scientific knowledge to support the meaningful learning of physics curriculum. The epistemological aspects of the developed materials illuminate the nature of scientific knowledge and its major features: objectiveness and cumulative nature. Teachers found the developed modules interesting, important but challenging their background and requiring special preparation. 相似文献

The aims of this study were to determine the underlying conceptual structure of the thermal concept evaluation (TCE) questionnaire, a pencil-and-paper instrument about everyday contexts of heat, temperature, and heat transfer, to investigate students’ conceptual understanding of thermal concepts in everyday contexts across several school years and to analyse the variables—school year, science subjects currently being studied, and science subjects previously studied in thermal energy—that influence students’ thermal conceptual understanding. The TCE, which was administered to 515 Korean students from years 10–12, was developed in Australia, using students’ alternative conceptions derived from the research literature. The conceptual structure comprised four groups—heat transfer and temperature changes, boiling, heat conductivity and equilibrium, and freezing and melting—using 19 of the 26 items in the original questionnaire. Depending on the year group, 25–55% of students experienced difficulties in applying scientific concepts in everyday contexts. Years of schooling, science subjects currently studied and physics topics previously studied correlated with development of students’ conceptual understanding, especially in topics relating to heat transfer, temperature scales, specific heat capacity, homeostasis, and thermodynamics. Although students did improve their conceptual understandings in later years of schooling, they still had difficulties in relating the scientific concepts to their experiences in everyday contexts. The study illustrates the utility of using a pencil-and-paper questionnaire to identify students’ understanding of thermal concepts in everyday situations and provides a baseline for Korean students’ achievement in terms of physics in everyday contexts, one of the objectives of the Korean national curriculum reforms. 相似文献

Existing research on students’ conceptions contain competing philosophical positions concerning the nature of students’ ideas—whether those ideas are coherent, systematic and theory-like, or fragmented and incoherent. Existing research has also focused primarily on studies of individual conceptions rather than investigating multiple, related conceptions. Nevertheless, there is wide agreement among researchers and teachers alike that the ideas students bring to a learning situation are fertile ground for investigation, and that students’ ideas should be taken into consideration when planning science instruction. The purpose of this study was to examine the representational, conceptual framework, and contextual consistency aspects of two students’ ideas across concepts of evaporation, condensation, and boiling. Knowing the consistency students express for each specific concept, and how well they integrate these related concepts, would offer insights that could potentially impact student learning. We present two case studies here that highlight the degree of consistency expressed by two students across different representations for each target concept and in instances where these conceptions are related to one another. Findings from this study highlight the need for attention to the consistency of students’ ideas across multiple, related concepts. Implications from this study support our recommendation for metaconceptual teaching strategies that would help students examine different representations for the same concept and also to examine the consistency of their ideas across multiple conceptions. 相似文献

This paper explores the attitudes and perceptions of three cohorts of Australian humanities and social science undergraduate students towards peer assessment. It seeks to gain a deeper understanding of local dissatisfaction with peer assessment through an in‐depth analysis of students’ contributions to focus group discussions. Responding to education theorists’ claims that peer and other forms of innovative assessment empower students, the paper concentrates on themes of power evident within students’ narratives. The interpretive framework coheres around four interrelated conceptions of power: sovereign, epistemological, disciplinary and structural. Students were found to support the notion of peer assessment as a formative exercise, yet were highly critical of it as a summative practice. Significantly, some of the students’ dissatisfaction stemmed from broader changes across the higher education sector more generally. The paper draws attention to the need for this to be taken into account when considering assessment as a technology of power and empowerment. 相似文献

Thermal physics is in the realm of everyday experience, underlies current environmental concerns, and underpins studies in sciences, health and engineering. In the state of NSW in Australia, the coverage of thermal topics in high school is minimal, and, hence, so is the conceptual understanding of students. This study takes a new approach at exploring conceptions of students with a qualitative analysis facilitated by NVivo complemented with reference to sociocultural ideas of learning. A 2-part pen and paper question was given to 598 first year university students of different educational backgrounds (and therefore physics expertise). ‘The Question’ was based on 2 familiar scenarios and required the selection of a concept first, followed by an explanation. The results showed that concepts were favoured based on a student’s everyday experience and their curriculum through high school, and some were more effective than others in making scientifically congruent responses. The reported thermal physics alternative conceptions were also examined in our sample, and students’ reasoning behind such conceptions indicate that some conceptions do not inhibit scientifically congruent responses whilst others do. The results implicate language and the everyday experiences of the student in the teaching and learning of thermal physics. 相似文献

Over a wide range of subject areas students exhibit persistent conceptions contrary to the prevailing scientific concepts. The same alternative conceptions in physics are reported to exist across many countries, within a variety of cultural and environmental contexts. Also, many alternative conceptions show striking similarities with difficulties encountered in the historical development of physics. What is the reason for these similarities? Is intuitive science learned or triggered? And, if similar brain structures are responsible for common-sense theories, in what way then are cultural factors still important in the teaching-learning process? The influence of cultural factors will be discussed on the basis of literature available on this topic. Data collected by the authors in the Netherlands, Indonesia and countries in Africa are also taken into consideration. A distinction is proposed between alternative conceptions some of which may be universal and some dependent on culture. The same distinction is made regarding ways of reasoning and epistemology. It is suggested that the effectiveness of methods for the remediation of alternative conceptions is strongly influenced by cultural aspects of the teaching-learning process. 相似文献

The argument in this paper has two parallel strands. One describes students’ conceptions of biology; the other uses Habermas’ epistemological framework as a way of suggesting alternative curricular questions. The two strands are brought together, since the research methodology is the situational‐interpretive curriculum orientation, and the findings are considered from this orientation. Thus, the data from the first strand is examined from the second strand, and consequently, new questions arise. With traditional knowing, science education researchers “know” how students conceive of the science they are learning by having students react to statements of the researcher's conception of science. This way of knowing has been criticized because it depends upon the researcher's set of ways of looking at students’ conceptions. As such, it does not treat students’ knowledge as a first‐order phenomena; knowing is, rather, a second‐order phenomena since it is filtered through another person's conceptions. In this study the Habermasian framework is used as an alternative perspective of knowledge which allows students’ conceptions to be examined at the level at which the conceptions were constructed. The study suggests that students conceptualize biology from three distinct philosophical positions; but when these positions are considered from the Habermasian framework, they all are examples of the empirical‐analytic tradition. As such, the students’ conceptions have not gone beyond explanatory knowledge, and this raises questions about the curriculum. 相似文献

Research suggests that conventional teaching techniques have proved largely ineffective for dealing with the problem of science students’ misconceptions or alternative frameworks. This paper reports an investigation whereby inter‐personal conflict within dyadic interactions is used as a strategy for promoting development towards correct scientific conceptions in specific areas of electrical circuits and mechanics amongst first‐year tertiary physics students. The data indicate that a large number of physics students at the tertiary level hold non‐scientific conceptions of these physical phenomena. The dyadic interaction strategy proved effective as a means of encouraging students to actively and closely consider their own thinking about basic physical concepts. Further, results highlight the importance of inter‐personal conflict in the process of conceptual change. 相似文献

Indigenous knowledge is at risk of being lost in many parts of the world. It is important to find ways to preserve it for both cultural and practical reasons, since it is often well-suited to addressing local needs using available resources. If indigenous knowledge can be incorporated into school science curricula, it can also provide familiar contexts within which to learn scientific concepts, as well as helping the younger generation to recognise its value. The purpose of this study was to identify indigenous knowledge that could be related to physics concepts, with a view to integrating it into school curricula. Twenty-nine senior citizens from Chókwé, a rural village in Mozambique, volunteered to participate in two sets of in-depth interviews. The first set of interviews was individual and unstructured in order to explore which aspects of indigenous knowledge might be related to physics concepts. The second set was semi-structured and conducted in small groups in order to probe participants’ understanding and application of the identified physics concepts. The results showed that participants had indigenous knowledge that was useful to them in their daily lives and that were applications of thermal physics, static electricity and mechanics concepts. In some cases participants’ explanations were aligned to physics explanations, in some cases they were similar to students’ alternative conceptions identified in the literature, and in other cases they referred to supernatural phenomena. 相似文献

This study reports on research examining what students think about aspects of solution chemistry and seeks to establish what
alternative conceptions they hold in this area. To achieve this aim the researchers developed a test comprising of open-ended
questions that evaluated students understanding of solution chemistry. The test was administered to 441 students selected
randomly from different grades, grade 7 through grade 10. The research findings suggest that students have difficulty at comprehending
the investigated concepts in solution chemistry. Alternative conceptions about the concepts of dissolution, chemical bonding,
evaporation and condensation influence latter learning. Interestingly, the grade 9 students have the least percentages, except
for Item 3, amongst grades in terms of alternative conception. Also, students' alternative conceptions are also stored in
long-term memory and interact with each another. In the light of the findings, it can be suggested that the future research
may need to focus on classifying of students' responses in terms of categories in understanding such as propositions, strings,
images, episode, intellectual skills and cognitive strategies. 相似文献

The Augmented Reality (AR)-based learning environment not only provides educators with novel ways to present learning materials but also give learners the opportunity to spontaneously interact with the material. Previous studies have shown that AR has many advantages in education; however, few focuses on the mechanisms behind promoting inquiry motivation, such as the effect of AR on learners’ self-efficacy and conceptions of learning. This study developed an AR-based wave-particle duality learning application, “AROSE,” to explore the effect of AR technology on students’ self-efficacy and conceptions of learning physics. A quasi-experimental study method was used, and 98 high school students aged between 16 and 18 were randomly assigned to experimental and control group. After a 4-week intervention, it was found that integrating AR technology into physics classrooms can (1) significantly enhance students’ physics learning self-efficacy, as indicated by understanding of concepts, higher-level cognitive skills, practice and communication; (2) guide students to be more inclined to higher-level conceptions of learning physics rather than lower ones; and (3) stimulates students’ motivation to learn more deeply. 相似文献

Lay conceptions of energy often conflict with scientific knowledge, hinder science learning and scientific literacy, and provide a basis for ungrounded beliefs. In a sample of Finnish upper secondary school students, energy was attributed with features of living and animate beings and thought of as a mental property. These ontologically confused conceptions (OCC) were associated with trust in complementary and alternative medicine (CAM), and independent of scientifically valid conceptions. Substance-based energy conceptions followed the correlational pattern of OCC, rather than scientific conceptions. OCC and CAM decreased both during the regular school physics curriculum and after a lesson targeted at the ontological confusions. OCC and CAM were slightly less common among students with high actively open-minded thinking, low trust in intuition and high need for cognition. The findings are discussed in relation to the goals of scientific education. 相似文献

Recent research has shown interest in studying the relationship between epistemological beliefs and numerous aspects of learning. A new question interests us: Is this kind of relationship homogeneous across cultures? This study focuses on the relationship between epistemological beliefs, learning conceptions, and approaches to study. A sample of Chinese (n = 299) and Flemish (n = 324) first-year university students in Beijing, China and Flanders were involved in the study. A structural equation model (SEM) relating the three concepts was applied to the sample data, largely confirming the theoretical assumptions. The results validated the postulation that epistemological beliefs predict students' conceptions of learning, which in turn are related to specific approaches to study. Multiple group analysis using SEM was applied and the structural weights model was confirmed across the two cultural groups. Mean level variations of the three main concepts were detected between the Chinese and Flemish groups. The results identified in the study offer valuable contributions to a deeper understanding of the interplay between epistemological beliefs and student learning from a cross-cultural perspective. Implications for learning and instruction are discussed. 相似文献

Our work extends a previous study of epistemological presuppositions in teaching quantum physics in upper scientific secondary school in France. Here, the problematic reference of quantum theory’s concepts is treated at the ontological level (the counterintuitive nature of quantum objects). We consider the approach of using narratives describing possible alternative worlds to address the issue. These possible worlds are based on the counterfactual logic developed in the work of D. Lewis. We will show that the narratives written by G. Gamow describe such possible worlds. Some parts of these narratives are found in textbooks in France. These worlds are governed by laws similar to but importantly different from those in our real world. They allow us to materialize properties inaccessible to everyday experience. In this sense, these fiction stories make ontological propositions concerning the nature and structure of the fundamental elements of our physical universe. 相似文献
