This study deals with the school instruction of the concept of weight. The historical review reveals the major steps in changing weight definition reflecting the epistemological changes in physics. The latest change drawing on the operation of weighing has been not widely copied into physics education. We compared the older instruction based on the gravitational definition of weight with the newer one based on the operational definition. The experimental teaching was applied in two versions, simpler and extended. The study examined the impact of this instruction on the middle school students in regular teaching environment. The experiment involved three groups (N = 486) of 14-year-old students (ninth grade). The assessment drew on a written questionnaire and personal interviews. The elicited schemes of conceptual knowledge allowed to evaluate the impact on students’ pertinent knowledge. The advantage of the new teaching manifested itself in the significant decrease of the well-known misconceptions such as “space causes weightlessness,” “weight is an unchanged property of the body considered,” and “heavier objects fall faster”. The twofold advantage—epistemological and conceptual—of the operational definition of weight supports the correspondent curricular changes of its adoption.  相似文献

The purpose of this study was, first, to understand the item hierarchy regarding students’ understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students’ USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6 aspects of USM, namely, model type, model content, constructed nature of models, multiple models, change of models, and purpose of models. Moreover, 10 representations of models were included for surveying what a model is. Results show that the purpose of models and model type items covered a wide range of item difficulties. At the one end, items for the purpose of models are most likely to be endorsed by the students, except for the item “models are used to predict.” At the other end, the “model type” items tended to be difficult. The students were least likely to agree that models can be text, mathematical, or dynamic. The items of the constructed nature of models were consistently located above the average, while the change of models items were consistently located around the mean level of difficulty. In terms of the natural progression of USM, the results show significant differences between 7th grade and all grades above 10th, and between 8th grade and 12th grade. The students in the 7th grade intervention group performed better than the students in the 7th and 8th grades who received no special instruction on models.  相似文献

To prepare Dutch students in education for critical situations in their professional life as a teacher, part of their training is to ask them to reflect upon their own experiences in their life as a child, a pupil and a student – experiences of crucial moments or with significant others which are still of the utmost importance to them. This article underlines the significance of so-called “experiential learning” in student career counselling. In this context, experiential learning is understood as an extension of in-depth reflection on critical incidents and critical persons in the biography of pre-service teachers. This reflection – customary and effective in Dutch teacher training – is a verbal process. However, this technique does not seem to be adequate for many students from other cultural backgrounds (e.g. second-generation descendants of migrant workers). By consequence, some of these students are not able to take newly offered information on board, but remain imprisoned in their own culture-related narrative, their own ethnic society of mind. Research has shown that for these students, psychodrama techniques, focusing on non-verbal and playful aspects of reflection, seem to be more suitable. The author of this article presents a sample case from a pilot study which used one of the psychodrama techniques called the empty chair. The findings of the pilot study are promising in the sense that experiencing different I-positions does seem to help students from other cultural backgrounds to develop agency in responding to hitherto unfamiliar and confusing situations.  相似文献

In recent years, research on higher education has increasingly examined the realities of internationalisation, with a particular focus on international students’ experiences and internationalisation at home programs. These studies have explored the friendships of international students, including their relationships with both locals and internationals from other countries. However, local students’ perspectives and experiences of friendship are largely absent from this literature. The few accounts examining local students’ lives explicitly focus on improving their cross-cultural knowledge and engagement, or on rare cases of local–international student friendships. The overriding assumption in this literature is that the understandings and social practises of local students are major barriers to their relationships with internationals. This paper addresses this gap by exploring local students’ perspectives on the absence of friendships with their international peers. We utilise findings from a research project on internationalisation at home, involving interviews and focus groups with local and international students and staff at an Australian university. Focusing on locals’ discussions of potential friendships with internationals, we propose that these missing friendships are an important area of study. We find that these friendships are missing for several interrelated reasons: local–international friendships are considered unnecessary and are therefore unimagined by locals, who tend to assume that similarity and affinity naturally lead to friendships, and the structures and spaces that might facilitate friendships are absent. Ultimately, uncovering why these friendships are missing sheds fuller light on how relationships might be facilitated, potentially informing and improving universities’ internationalisation initiatives.  相似文献

Measuring gifted and talented (GT) students’ perceptions of their GT label might seem to be a relatively straightforward affair. Most of this research uses survey methods that ask GT students to complete Likert scale or open-ended response questionnaires about their perceptions of the label and then presents results in clear and quantifiable terms, such as “X % of students hold positive perceptions of the GT label.” However, our qualitative study of GT students in two middle school social studies classrooms presents findings that not only trouble, but prompt questions about simple proclamations regarding GT students’ perceptions of the GT label. What we found was that given the opportunity to share their thoughts at length, this group of GT students expressed a range of often contradictory perceptions about their GT label. Students expressed multiple interpretations and perceptions of the GT label, as well as both embraced the label and rejected the label.  相似文献

Adopting Maria Manzon’s theoretical framework, which draws on Foucault and proposes that comparative education as an academic field is socially constructed, I suggest that the field is neither stable nor well defined. To demonstrate this, I conduct a content analysis of the Comparative Education Review, using Klaus Krippendorff’s methodological framework to study comparative and international education (CIE) researchers’ understanding of the national—and of their related knowledge production in the field. Many comparativists express interests in multiple countries, and their knowledge production takes the form of individual country studies. The countries are habitually studied using a “problem approach” focusing on one specific aspect of the country under investigation and using an associated social science methodology deemed appropriate. Few comparativists are making explicit use of or reference to any methodology that is unique to comparative education. Efforts to catalog and systematize CIE research have demonstrated that the field is becoming so inclusive that it hardly is distinguishable from educational studies as a whole. Hence, I suggest that instead of speaking about unifying features of the field, it may be more relevant to speak about frequent elements, such as a focus on the national, and a knowledge production characterized by the academic practitioner who desires to improve the education systems studied. A third frequent element may be the focus on educational development, thus justifying the label of “comparative, international, and development education.” One challenge of the field is its dependence on Western social science discourses, which may be marginalizing other voices.  相似文献

In 1991, David Macaulay was awarded the Randolph Caldecott Medal for his picturebook, Black and White (1990). He believed the Caldecott committee’s choice communicated many messages to readers of all ages: “that it is essential to see, not merely to look; that words and pictures can support each other; that it isn’t necessary to think in a straight line to make sense; and finally that risk can be rewarded” (p. 419). This article focuses on how Macaulay uses play to engage readers—to arouse their curiosity, to make them think, and to incite them to ‘see things’ in Black and White. Excerpts from Grade 5 students’ written responses illustrate some of their responses to and interpretations of various kinds of narrative and illustrative play in Black and White.  相似文献

A well-ordered biological complex can be formed by the random motion of its components, i.e. self-assemble. This is a concept that incorporates issues that may contradict students’ everyday experiences and intuitions. In previous studies, we have shown that a tangible model of virus self-assembly, used in a group exercise, helps students to grasp the process of self-assembly and in particular the facet “random molecular collision”. The present study investigates how and why the model and the group exercise facilitate students’ learning of this particular facet. The data analysed consist of audio recordings of six group exercises (n?=?35 university students) and individual semi-structured interviews (n?=?5 university students). The analysis is based on constructivist perspectives of learning, a combination of conceptual change theory and learning with external representations. Qualitative analysis indicates that perceived counterintuitive aspects of the process created a cognitive conflict within learners. The tangible model used in the group exercises facilitated a conceptual change in their understanding of the process. In particular, the tangible model appeared to provide cues and possible explanations and functioned as an “eye-opener” and a “thinking tool”. Lastly, the results show signs of emotions also being important elements for successful accommodation.  相似文献

A study is presented that explores how students’ knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students’ knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students’ conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment.  相似文献

This paper examines how the definition and interpretation of the concept gewu zhizhi 格物致知 (investigating things and extending knowledge), evolved along with Chinese intellectual efforts to construct the framework for Chinese learning which, in turn, had a profound impact on the development of educational curricula in different historical periods. In Confucian philosophy, “practicality” appears ambivalent, as it can refer to moral cultivation in daily life or knowledge in the material world. Such ambivalence, embodied in the evolution of the concept of gewu zhizhi, can be interpreted as a Chinese search for a well-rounded curriculum in education. Within this framework, this paper traces the origin of the concept in The Great Learning, and investigates how it was developed to refer specifically to natural studies and then to scientific knowledge introduced into China in the late Qing period. This historical reflection on Chinese education points to the shared humanistic values in the Confucian approach to education and in the Renaissance ideal of a liberal education. It calls for a search for a common humanity in rethinking the content and aim of a modern Chinese education.  相似文献

This article reports the findings of classroom research exploring the potential of posing challenging mathematical problems situated in real-world financial contexts to activate mathematical knowledge, skills and reasoning. The Organisation for Economic Cooperation and Development (OECD) Programme for International Student Assessment (PISA) 2012 mathematical literacy assessment framework (OECD, 2013) provided theoretical framing for the study, which examined the use of a “financial dilemma” titled Shopping for shoes in a Year 5/6 composite class in a suburban Australian primary school. The social and mathematical dimensions of the task, together with a particular lesson structure, successfully engaged 10 to 12-year-old students in exploring mathematics through a financial problem-solving experience. The findings reveal that students’ notions of friendship and fairness guided the way they formulated the problem and employed mathematics. Strategies intended to encourage students to interpret the alignment and reasonableness of their social and mathematical thinking against the problem context were critical to the lesson.  相似文献

Spelling is a challenge for individuals with dyslexia. Phoneme-to-grapheme correspondence rules are highly inconsistent in French, which make them very difficult to master, in particular for dyslexics. One recurrent manifestation of this inconsistency is the presence of silent letters at the end of words. Many of these silent letters perform a morphological function. The current study examined whether students with dyslexia (aged between 10 and 15 years) benefit from the morphological status of silent final letters when spelling. We compared, their ability to spell words with silent final letters that are either morphologically justified (e.g., tricot, “knit,” where the final “t” is pronounced in morphologically related words such as tricoter, “to knit” and tricoteur “knitter”) or not morphologically justified (e.g., effort, “effort”) to that of a group of younger children matched for reading and spelling level. Results indicated that the dyslexic students’ spelling of silent final letters was impaired in comparison to the control group. Interestingly, morphological status helped the dyslexics improve the accuracy of their choice of final letters, contrary to the control group. This finding provides new evidence of morphological processing in dyslexia during spelling.  相似文献

This article explores posthumanism as a philosophy that emphasizes human relationships with the natural world by examining representations of animality, both in children’s literature (e.g. titles such as Where the Wild Things Are, Wild, Virginia Wolf, and No Fits, Nilson!) and in children’s play in order to better understand the significance of philosophy in children’s literature and lives. By fostering a feeling of “necessary wilderness,” or connection to nature (Almond, 2011, p. 110), and by practicing a sense of being in nature, “keeping some wildness always alive” (Lerman, 2012, p. 311) through literary engagement and animal play, the authors suggest that children and adults can maintain an interconnectedness with the natural world, even when they cannot be in it themselves. Through a mixed methods approach that combines educational theory, ecocriticism, and qualitative research, we discuss links between children’s stories and bodies, identifying how becoming animals through narrative engagement and play reflects posthumanist theory in practice, and encourages a child’s embodied knowledge of nature. The authors also speak to the ways that embodied education approaches that encourage animal play and “expressive literary engagement” [Sipe, 2002, pp. 476–483]) can support a shifting and necessary worldview informed by posthumanism, suggesting that philosophical change is necessary if humanity aims to survive the ecological and technological changes to come.  相似文献

The notion of “praxeology” from the anthropological theory of the didactic (ATD) can be used as a framework to approach what has recently been called the networking of theories in mathematics education. Theories are interpreted as research praxeologies, and different modalities of “dialogues” between research praxeologies are proposed, based on alternatively considering the main features and proposals of one theory from the perspective of the other. To illustrate this networking methodology, we initiate a dialogue between APOS (action-process-object-schema) and the ATD itself. It starts from the theoretical component of both research praxeologies followed by the technological and technical ones. Both dialogue modalities and the resulting insights are illustrated, and the elements of APOS and the ATD that the dialogue can promote and develop are underlined. The results found indicate that a complete dialogue taking into account all components of research praxeologies appears as an unavoidable step in the networking of research praxeologies.  相似文献

This study investigated the effects of teachers’ use of focus questions on students’ knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in individual lessons (Forbes & Davis, 2010). In Wadouh’ study, students answered a knowledge test before and after the lesson on “blood and the circulatory system” and one lesson per teacher was videotaped to investigate teaching practices in grade 9 biology classrooms. Students also completed a post-unit concept mapping exercise and a motivation-interest questionnaire. In this study, 30 lesson videos selected from 47 were re-analyzed for teachers’ use of focus questions—no focus questions, non-specific or simple focus questions, and specific and challenging focus questions. Individual students’ scores in the concept mapping exercise were aggregated as students’ topic-related knowledge structure. Multilevel analyses revealed a significant positive effect of teachers’ use of specific and challenging focus questions on students’ topic-related knowledge structure. Furthermore, a comparative case analysis of the classroom teaching-learning process was conducted in four lessons where teachers used specific and challenging focus questions in two of the lessons and non-specific or simple focus questions in the other two lessons. The findings indicate that specific and challenging focus questions anchored lessons on students’ co-construction of scientific explanations by activating their pre-instructional ideas, whereas non-specific or simple focus questions anchored lessons on their accumulation of canonical scientific knowledge. This study’s limitations and implications for teacher education reform are discussed.  相似文献

This longitudinal study examined the role of metaconceptual awareness in the change and the durability of preservice teachers’ conceptual understandings over the course of several months. Sixteen preservice early childhood teachers participated in the study. Semi-structured interviews were conducted to reveal the participants’ conceptual understandings of lunar phases (pre, post, and delayed-post) and level of metaconceptual awareness (delayed-post only). Based on the change and stability in participants’ conceptual understandings from pre to post and from post to delayed-post interviews, participants’ conceptual understandings were assigned into three groups that described the profile of their long-term conceptual understandings: “decay or stability”, “continuous growth”, and “growth and stability”. The results indicated that participants in the “continuous growth” and “growth and stability” groups had significantly higher metaconceptual awareness scores than participants in the “decay or stability” group. The results provided evidence that metaconceptual awareness plays a more decisive role in the restructuring of conceptual understandings than the durability of conceptual understandings.  相似文献

In the present paper, we report on the idea of exchanging educational innovations across European countries aiming to shed light on the following question: how feasible and useful is it to transfer an innovation across different national educational settings? The innovation, in this case, Inquiry-Based Teaching Learning Sequences, is recognized as a crucial component of renewal science teaching in European countries. Two local working groups from two different Universities, in Finland and Greece, were created consisting of researchers and experienced primary teachers. The transfer from Greece to Finland was rather challenging because of the differences between the two educational contexts. The initial, as well as the revised Teaching Learning Sequence, were implemented for 11–12-year-old students including the content to be taught, that is Floating-Sinking phenomena and density, and the learning environment aspects such as learning Control of Variables Strategy. A combination of qualitative and quantitative research methods was implemented in order to formulate concrete recommendations on feasible and useful aspect. The feasible aspect adduces answers to the query of “how” this transfer worked in practice. Concerning this aspect, the recognition of what is innovative for each national partner was recognized as a crucial factor for the design and revision of both Teaching Learning Sequences. The useful aspect illuminates students’ improvement in the achievement of conceptual as well as procedural knowledge. The results revealed that the psychological paths that bring about this success are ecumenical and independent of the history of the educational group.  相似文献
