Analogies offer conceptual models for supporting the development of understanding. Contrary to some expectations, there is growing evidence that young children can reason analogically. Much of this evidence comes from experiments intended to test psychological theories. This study aimed to gauge the practical potential of analogy in topics often considered by teachers difficult for young children to understand. Aspects of young children's understanding of current electricity were compared in two conditions, namely with and without an analogy (87 and 89 children, respectively; 6‐7 years of age). The results indicated that the analogy was of practical value in teaching for understanding. It is suggested that their bases be carefully prepared prior to teaching the target topic and that what is to be understood is modelled directly and is explicitly related to its equivalent in the topic. Further investigations to determine conditions for the effective use of analogies when teaching young children, who benefits particularly and in what ways seem warranted.  相似文献

The ability to make inferences about what one’s peers know is critical for social interaction and communication. Three experiments (n = 309) examined the curse of knowledge, the tendency to be biased by one’s knowledge when reasoning about others’ knowledge, in children’s estimates of their peers’ knowledge. Four- to 7-year-olds were taught the answers to factual questions and estimated how many peers would know the answers. When children learned familiar answers, they showed a curse of knowledge in their peer estimates. But, when children learned unfamiliar answers to the same questions, they did not show a curse of knowledge. These data shed light on the mechanisms underlying perspective taking, supporting a fluency misattribution account of the curse of knowledge.  相似文献

Rainfall is a key process in the water cycle, the most structured scientific knowledge about water movement on Earth. Nevertheless, despite being a common topic covered in school science, it entails several cognitive difficulties for young children. This study uses a pictorial task and semi-opened questions to examine primary (11/12 years old) and secondary (12/13 years old) students’ understanding of the elements and processes involved in the hydrologic cycle and how they are integrated into their explanations regarding the rainfall phenomenon. Overall, we have found that the studied children’s (n = 246) conceptual knowledge increases with age. However, they have an incomplete perception of the mechanism of rainfall and its integration into the water cycle. In fact, not all the students have a cyclic notion of water dynamics; they also miss the inclusion and role of groundwater in water systems and present misconceptions regarding key processes, such as condensation and evaporation. Regarding the two diagnostic tools (drawings and questionnaires) used to study children’s understanding, although questionnaires seem more appropriate for assessing lower conceptual levels, each methodological approach is useful for detecting different key concepts and misconceptions related to the rainfall phenomenon and related water cycle. Consequently, a mixed research design using different methods is advised for a comprehensive study of students’ conceptions.

Profound misunderstandings of the implications of rhyme and analogy research (sometimes called ‘new phonics’) for classroom teaching still appear regularly in the reading literature. It has been argued that ‘rhyme and analogy’ researchers do not believe in teaching children grapheme-phoneme correspondences (Chew, 1997). Rhyme and analogy has also been branded as ‘analytic phonics’, which is argued to be inferior to ‘synthetic’ phonics (Watson and Johnston, 1999). Such misconceptions are confusing the debate over how best to teach ‘phonics’, following the publication of the National Literacy Framework (DfEE, 1998). For example, some authors are suggesting that teachers should replace an emphasis on phonological awareness and onset-rime with a teaching programme based on ‘synthetic’ phonics (Deavers and Solity, 1998; Watson and Johnston, 1999). This paper discusses the implications of Goswami and Bryant’s (1990) theory about important causal connections in reading for classroom teaching, and reviews more recent ‘rhyme and analogy’ research within this framework. New research on the nature of the English spelling system and the representation of linguistic knowledge is also discussed. The importance of taking a balanced approach to phonics instruction and teaching children correspondences between letters and phonemes and letter sequences and rimes is emphasised.  相似文献

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.  相似文献

Conceptual change may be considered as a process of coming to view one theory or model as having more explanatory power than others. Various theorists have described how an individual's understanding of a concept may be multifaceted; how conceptual frameworks develop in a cognitive ecology, and are subject to selection pressures; and how alternative frameworks compete in terms of their explanatory coherence. The present paper applies these ideas to a case study of learning in science. It is argued that conceptual development may be described in terms of a gradual shift in which of several alternative explanatory principles is the learners' preferred choice. The case study illustrates the long-term nature of conceptual change, as a learner comes to see the limitations of one explanatory framework, and the scope for exploring and developing another.  相似文献

This study examined prospective teachers’ (PSTs) ability to recognize evidence of children’s conceptual understanding of mathematics in three content areas before and after an instructional intervention designed to support this ability. It also investigates the role PSTs’ content knowledge plays in their ability to recognize children’s mathematical understanding. Results of content knowledge assessments administered at the beginning of the study revealed that content knowledge did seem to support PSTs’ analyses of children’s understanding when the child’s response demonstrated understanding or demonstrated a misconception. Content knowledge did not seem to support PSTs’ analyses of children’s procedural responses, as many PSTs with good content knowledge initially characterized procedural solutions as evidence of conceptual understanding. Similarly, content knowledge did not seem to support PSTs’ analyses of children’s responses with features commonly associated with understanding but not evidence of understanding. After the instructional intervention consisting of three multifaceted lessons in which PSTs examined many examples of student thinking, they showed improved ability to analyze responses with conceptual features and no evidence of conceptual understanding and responses demonstrating procedural knowledge. Results suggest that content knowledge is not sufficient for supporting PSTs’ analysis of children’s thinking, and that building activities such as the intervention into content courses may help develop this ability. Implications for teacher education programs and future research are considered.  相似文献

Research Findings: In this research we explore the relationship between young children’s number knowledge and their measurement of length. First, we examined 4- to 5-year-olds’ (kindergartners’) understanding of and preference for using standard or nonstandard units to measure length. Second, we investigated whether the following tasks were related to children’s understanding of using standard (i.e., rulers) and nonstandard (i.e., blocks) units to measure length: (a) counting and written number identification knowledge, (b) symbolic or nonsymbolic number magnitude comparison ability, and (c) approximate number line estimation ability. Third, we examined whether understanding these number tasks predicted understanding how to measure length for both standard and nonstandard units. Our results show that young children prefer to use standard units of measurement when given a choice, and some of these children use a ruler correctly. Our results also show an important relationship between children’s understandings of numbers and measurement. Practice or Policy: Given children’s preference for rulers, introducing both nonstandard and standard units in early learning settings concurrently rather than consecutively is recommended for practice.  相似文献

While the policy approach in Urban Regeneration Partnership tends to be viewed as participatory governance using an urban studies lens, this article posits an alternative theorisation that takes an adult education perspective. We draw from Lefebvre’s notion of space, Engeström’s Cultural Historical Activity Theory and Holand et al.’s concept of positionality and social identity to theorise Urban Regeneration Partnership as expansive participation that acknowledges discursive struggle and contradiction in authentic democratisation. We argue for a multiscalar understanding of citizenship that attends to sociocultural conditions, challenges hegemonic spatial modalities and inculcates conditions for transformative agency. Our theorising is illustrated using data from a doctoral study examining one Urban Regeneration Partnership in the Republic of Ireland. Three themes emerged from the study: market-led discourse of transformation versus a narrative of community; rhetoric of empowerment versus the unequal positioning of residents, and the dominant hegemony of official knowledge versus community-based experiential knowledge. The article examines whether the academy can make a difference in people’s lives through challenging the prevailing orthodoxy, revealing unexamined assumptions and offering alternative frameworks for deeper understanding of the policy cycle in Urban Regeneration Partnerships.  相似文献

In this article, the theoretical framework of developmental pedagogy is presented as a tool in studying and developing children’s knowing within the arts. The domains of art focused on are music, poetry and dance/aesthetic movement. Through empirical examples from a large‐scale research project, we illustrate the tools of developmental pedagogy and show how this perspective contributes to our understanding of children’s learning of music, dance and poetry. More specifically, we will analyse: (a) the important role of the teacher in children’s learning within the arts; (b) the importance of conversing when learning the arts; (c) what constitutes the knowledge, what we refer to as ‘learning objects’, to be appropriated within the three domains of art focused on; and (d) how to conceive of progression in children’s knowing within the arts.  相似文献

Key elements of the structure and function of models in mathematics and science are identified. These elements are used as a basis for discussing the development of model‐based reasoning. A microgenetic study examines the beginnings of model‐based reasoning in a pair of fourth‐ and fifth‐grade children who solved several problems about chance and probability. Results are reported in the form of a cognitive model of children's problem‐solving performance. The cognitive model explains a transition in children's reasoning from tacit reliance on empirical regularity to a form of model‐based reasoning. Several factors fostering change in children's thinking are identified, including the role of notations, peer interaction, and teacher assistance. We suggest that model‐based reasoning is a slowly‐developing capability that emerges only with proper contextual and social support and that future study should be carried out in classrooms, where these forms of assistance can also be part of the object of study.

Model‐based reasoning is a significant intellectual milestone because it bridges the worlds of personal, intuitive knowledge, on the one hand, and mathematical‐scientific theory, on the other. However, across disciplines, consensus is still forming about what model‐based reasoning comprises, and there is little knowledge about its ontogenetic origins or how it develops. We consider analogy as the core of modeling, because in model‐based reasoning a system in one domain is used to understand a system in another. To understand how models come to play a role in reasoning, it is important to initiate study of their origins. Accordingly, we report a microgenetic study examining the beginnings of model‐based reasoning in a pair of young children solving problems about chance and probability. In this study we are engaged in the enterprise of modeling the development of modeling. That is, we report our results in the form of a cognitive model of children's problem‐solving performance that explains a transition in reasoning from a tacit reliance on empirical regularity to a form of model‐based reasoning. It is important to note the two distinct meanings for the term model used in this article. The first describes how children come to understand and appropriate a system of reasoning exemplified in practices of modeling. The second describes a research tool, a model of human reasoning—specifically, how children in this study began to use models of probability to reason about uncertain events. In this report, we use the terms model or model‐based reasoning to refer to the former interpretation, whereas references to a cognitive model denote the simulation of children's thinking—in this case, implemented as a computer program.

Before describing the empirical work, we first identify some key elements of the structure and function of models. Next, these elements of modeling are used as the basis for generating some conjectures about the development of model‐based reasoning. We describe a task that we used as a window to understanding progression in student reasoning toward reliance on models as tools for thought. We present our rationale for developing cognitive models of student performance and explain some choices concerning the implementation of the cognitive model reported here. Finally, we turn to the children's performance on chance and probability tasks and explain how that performance illuminates both what children do not understand about models and the kinds of relevant knowledge that they are acquiring.  相似文献

In order to teach about sustainability, teachers need to be able to translate their personal understanding of this concept into their pedagogy in ways that make it accessible to their learners. This translation process is known as pedagogical content knowledge (PCK). This study investigated the way that two teachers translated their understanding of sustainability into their pedagogy and the effects of this translation on children’s learning (n?=?18). Two interpretive case studies were constructed. Data were generated using interviews and documents. Two frameworks were used to analyse the data. One was a definition of sustainability and the other a model of PCK expressed as pedagogical context knowledge (PCxK) that consisted of four components. The findings showed that the translation of sustainability was a complex interaction of three of the PCxK components with some use of the fourth. Some children developed an understanding of sustainability but only two were able to link their understanding with the scientific concepts taught resulting in ‘diffused learning’. Also, these findings suggest that while the PCxK model used to analyse the translation process had a degree of precision and heuristic power, further refinement is needed in order for this model to explicate teachers’ PCK.  相似文献

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students’ mechanistic reasoning across scientific content areas. We argue that these characteristics can be represented as epistemic heuristics, or ideas about how to direct one’s intellectual work, that implicitly guide mechanistic reasoning. We use this framework to characterize middle school students’ written explanatory accounts of two phenomena in different science content areas using these heuristics. We demonstrate evidence of heuristics in students’ accounts and show that the use of the heuristics was related to but distinct from science content knowledge. We describe how the heuristics allowed us to characterize and compare the mechanistic sophistication of account construction across science content areas. This framework captures elements of a crosscutting practical epistemology that may support students in directing the construction of mechanistic accounts across content areas over time, and it allows us to characterize that progress.  相似文献

Grounded in Vygotsky’s cultural-historical theory, this paper examines how often teachers are involved in children’s imaginative play and discusses their beliefs about their role in supporting children’s imaginative play. To investigate this problem, video (65 hours of digital observations) and interview data (two hours and 30 minutes) of 60 children with 7 teachers from two preschools in Australia were analysed. Using Vygotsky’s [1966. “Play and Its Role in the Mental Development of the Child.” Voprosy Psikhologii 12 (6): 62–76] cultural-historical concept of play, and Kravtsov and Kravtsova’s [2010. “Play in the L.S. Vygotsky’s Nonclassical Psychology.” Journal of Russian and East European Psychology 48 (4): 25–41] conception of ‘subject positioning’ (being inside and outside of the play), it was found that despite the general importance of play, teachers’ involvement in developing children’s imaginative play appears to be minimal. The interviews showed that teachers’ beliefs about their role in children’s imaginative play are directly related to the distance of their physical proximity and understanding of the play narrative being enacted. This paper argues that focusing on teachers’ involvement in children’s play is an important but under-researched dimension of play-based pedagogies in early childhood education.  相似文献

Prior research in both education and cognitive science has identified analogy making as a powerful tool for explanation as well as a fundamental mechanism for facilitating an individual's construction of knowledge. While a considerable body of research exists focusing on the role analogy plays in learning science concepts, relatively little is known about how instruction in the use of analogies might influence the teaching performance of preservice teachers. The primary objective of this study was to investigate the relationship between pedagogical analogy use and pedagogical reasoning ability in a sample of preservice elementary teachers (PTs), a group that has been identified for their particular difficulties in teaching science. The study utilized a treatment/contrast group design in which the treatment group was provided instruction that guided them in the generation of analogies to aid in the explanation phase of learning cycle lessons. A relationship between analogy use and positive indicants of teaching performance was observed and a case study of a low performing preservice teacher who drastically improved teaching performance using analogy‐based pedagogy is presented. A notable effect on conceptual understanding of Newton's Third Law as a result of two brief analogy‐based demonstration lessons was also observed. © 2007 Wiley Periodicals, Inc.

This study investigated eight prekindergarten teachers’ underlying assumptions about how children learn, and how these assumptions were used to inform and enact instruction. By contextualizing teachers’ knowledge and understanding as it is used in practice we were able to provide unique insight into the work of teaching. Participants focused on children’s ability to remember information, frequently through engagement and repetition. Teachers also anticipated what children would be learning in the early elementary years and taught that content, yet they did not necessarily expect children to remember the information, or even know if children learned the information. Implications for the design of both preservice and in-service teacher education are discussed. This includes helping teachers develop a strong foundational understanding of how children learn, establishing the pedagogical content knowledge relevant to teaching advanced symbol systems like literacy, and shifting pedagogical reasoning about practice. Given the link between the quality of instructional support and learning in the early years, developing the early childhood teaching force’s capacity to use knowledge to reason skillfully about teaching offers a critical lever for creating robust learning in the early years.  相似文献

This research examined children’s questions and the reactions to the answers they receive in conversations with adults. If children actively seek explanatory knowledge, they should react differently depending on whether they receive a causal explanation. Study 1 examined conversations following 6 preschoolers’ (ages 2–4 years) causal questions in naturalistic situations (using the Child Language Data Exchange System [CHILDES] database). Children more often agreed and asked follow‐up questions following adult explanations and, conversely, more often reasked their original question and provided their own explanation following nonexplanations. Study 2 replicated these patterns within an experimental task in 42 children ages 3–5 years. Children’s reactions following explanatory versus nonexplanatory information confirm that young children are motivated to seek causal information actively and use specific conversational strategies to obtain it.  相似文献

Many studies into learners’ ideas in science have reported that aspects of learners’ thinking can be represented in terms of entities described in such terms as alternative conceptions or conceptual frameworks, which are considered to describe relatively stable aspects of conceptual knowledge that are represented in the learner’s memory and accessed in certain contexts. Other researchers have suggested that learners’ ideas elicited in research are often better understood as labile constructions formed in response to probes and generated from more elementary conceptual resources (e.g. phenomenological primitives or ‘p‐prims’). This ‘knowledge‐in‐pieces perspective’ (largely developed from studies of student thinking about physics topics), and the ‘alternative conceptions perspective’, suggests different pedagogic approaches. The present paper discusses issues raised by this area of work. Firstly, a model of cognition is considered within which the ‘knowledge‐in‐pieces’ and ‘alternative conceptions’ perspectives co‐exist. Secondly, this model is explored in terms of whether such a synthesis could offer fruitful insights by considering some candidate p‐prims from chemistry education. Finally, areas for developing testable predictions are outlined, to show how such a model can be a ‘refutable variant’ of a progressive research programme in learning science.  相似文献

Wittgenstein explores learning through practice in the Philosophical Investigations by means of an extended analogy with games. However, does this concern with learning also necessarily extend to education, in our institutional understanding of the word? While Wittgenstein's examples of language learning and use are always shared or social, he does not discuss formal educational institutions as such. He does not wish to found a ‘school of thought’, and is suspicious of philosophy acting as a theory that can be applied to other areas of life. While Wittgenstein's focus on developing independent thinking was neither individualistic nor anti‐institutional, it did, however, focus on developing the thinking of his students rather than theorising about how this could be applied on a large scale. An analysis of Hermann Hesse's novel, The Glass Bead Game will help us to pick up where Wittgenstein deliberately left off—thinking about how (or if) one can institutionalise learning methods that encourage thinking for oneself. These differences in the writers’ treatment of education will become evident in the differences between their game analogies. While language‐games combat our ‘craving for generality’ in Philosophical Investigations, the Glass Bead Game represents this craving, and how it manifests itself throughout history in disciplines other than logic and philosophy of language. It also represents the potential for institutions to become insular, exclusive communities.  相似文献
