The study examined the extent to which case‐based learning could have an effect on pre‐service teachers' beliefs about the pedagogical uses of ICT in the classroom. One hundred second year early childhood pre‐service teachers enrolled in an ICT course participated in the study. Research data were collected with a questionnaire, reflection papers, course evaluations and focus interviews. The findings showed that initially the majority of pre‐service teachers had negative beliefs and certain misconceptions regarding the pedagogical uses of ICT and that case‐based learning effected their beliefs and conceptions. Future research studies should examine the extent to which a case‐based learning approach for the teaching of ICT in pre‐service teacher training can actually have an effect on appropriately integrating ICT into real classroom practices. 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

The present study draws on environmental science education to explore aspects of children’s conceptual change regarding hazardous household items. Twelve children from a fifth‐grade class attended a 30‐h teaching module of environmentally oriented science activities aimed at assessing their awareness about the environmental and health hazards posed by several typical household products. In‐depth interviews before, 2 weeks after, and 1 year after, the teaching intervention revealed that children followed three pathways of conceptual change ranging from the substantial alterations of their initial ideas to the qualitative enrichment of those ideas to the complete rejection of the new knowledge. Two components of the instructional intervention—the use of living organisms in classroom experiments, and group learning activities—along with the development of children’s situated metacognitive ideas facilitated their learning and increased the durability of the acquired knowledge. Additionally, sound indications concerning the situated nature and the social construction of the new knowledge were observed, as well as that in environmental education moral and value issues are closely related to knowledge. 相似文献

Assessment for learning? Thinking outside the (black) box 总被引：1，自引：0，他引：1
Eleanore Hargreaves Corresponding author 《Cambridge Journal of Education》2005,35(2):213-224
This article draws on a survey of 83 teachers, to explore the concepts of ‘assessment for learning’, ‘assessment’ and ‘learning’. ‘Assessment for learning’ is categorized as meaning: monitoring pupils' performance against targets or objectives; using assessment to inform next steps in teaching and learning; teachers giving feedback for improvement; (teachers) learning about children's learning; children taking some control of their own learning and assessment; and turning assessment into a learning event. Conceptions of assessment include assessment‐as‐measurement and assessment‐as‐inquiry. These conceptions are related to two conceptions of learning: learning‐as‐attaining‐objectives and learning‐as‐the‐construction‐of‐knowledge. The conceptions of assessment‐as‐measurement and learning‐as‐attaining‐objectives are dominant in English educational policy today. The article suggests that these conceptions need to be challenged and expanded, since conceptions held by those who have power in education determine what sort of assessment and learning happen in the classroom, and therefore the quality of the student's learning processes and products. 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

A constructivist framework was used in conjunction with an interpretive methodology to investigate the effect of an intervention using the metaphor “learning is constructing” on students' metacognition and learning processes. The metaphor was used to communicate with students regarding learning processes consistent with constructivism. Students were initially found to be generally non‐metacognitive regarding their learning processes. Despite some students possessing metacognitive knowledge consistent with a constructivist learning orientation, their pre‐intervention views and preferences in relation to teaching and learning were predominantly consistent with transmission models. The effect of the intervention on students' metacognition was variable. Some students became increasingly metacognitive and reported evidence of revision of their learning processes. Others reported little or no effect. The effects of the intervention can be partially explained by considering changes to students' metacognition as conceptual change. However, this study also shows that contextual factors are key determinants of students' propensity to enhance their metacognition and learning processes. This study highlights the potential of using metaphor as a means to assist teachers and students develop a shared language of learning in classroom settings. © 2001 John Wiley & Sons, Inc.

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media
campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS
has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions
of the disease, based on these media messages influence students’ development of conceptual understanding of the disease,
its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the
indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual
change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions
on classroom instruction about HIV/AIDS, involving 160 students aged 15–17, was conducted in four different Ugandan high schools:
girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology
lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned.
These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews.
Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications
for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with
the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what
is happening now—insensitivity to misconceptions about the disease—is needed. 相似文献

In this article we examine the teacher's role as a mediator of knowledge and cognitive learning in the classroom. We cite findings from the research areas of teacher effectiveness, teacher expertise, and curriculum knowledge. These data strongly support user‐friendly explicit methods of classroom teaching. We also discuss issues raised in conjunction with alternative conceptions of the teaching process. Finally, we note the importance of incorporating teacher effectiveness research findings into teacher education programmes, and of identifying the various misconceptions that have been used to criticise this body of information. 相似文献

Many teachers struggle to provide equitable opportunities for students with special educational needs (SEN) to learn science concepts in the inclusive classroom. This study examines the experience of teaching in an inclusive classroom using a conceptual change approach, the Thinking Frames Approach (TFA), incorporating the use of discrepant events, social construction of scientific conceptions followed by the production of multiple student‐generated representations of their understanding. An in‐depth case study is presented of the experience of Wayne, a student with complex SEN and the effect on his behaviour and science learning based on video/audio recordings of lessons, teacher journal entries, student artefacts, questionnaire results and interviews. It was found that there were positive effects for Wayne's learning using this approach including improved behaviour, greater feelings of self‐efficacy, increased participation in small group and class discussions and improved outcomes on the same assessment tasks as peers. It is suggested that the structured approach of the TFA, the communication of understanding in different modalities, particularly drawing, and the support of peers enabled Wayne to more deeply engage in construction of understanding and may provide teachers with an easy and effective approach to authentic inclusion where real conceptual gains are made by all students. 相似文献

Like their students, teachers may hold a variety of naïve conceptions that have been hypothesized to limit their ability to support students’ learning. This study examines whether changes in elementary students’ conceptions are related to their teachers’ content knowledge, attitudes, and understanding of conceptual change. The study takes place in the context of the adoption of a new unit on seasonal change in which students build and use sundials to observe seasonal differences in the apparent motion of the Sun across the sky. A mixed-method approach is used. Data sources include pre- and post-tests for students and teacher interviews and questionnaires. Results indicate that changes in students’ conceptions may be related to their teachers’ knowledge of the content, attitudes toward science, and understanding of conceptual change. One teacher had low attitude toward science and limited knowledge of conceptual change. After instruction, her students’ responses became less accurate but more homogeneous than before instruction. The other teacher had high attitude and moderate knowledge of conceptual change. Her students showed gains from pre- to post-test, including responses that were more scientifically accurate than the teachers’ initial answers. 相似文献

This study examined the classroom discipline orientations of pre‐service elementary teachers both before and after the student teaching experience. Prior to beginning and immediately after completing their full‐time student teaching experience, pre‐service teachers (N = 220) from three southeastern universities in the USA completed a discipline belief instrument which identified their preferred model of classroom discipline. The results showed that the student teaching experience significantly increased beginning teachers’ preferences toward a more assertive discipline model (Rules and Consequences) and decreased their preferences toward the humanistic discipline model (Relationship–Listening). These results demonstrate that the student teaching experience may be creating a dissonance in prior knowledge and beliefs, and experiences of pre‐service teachers in classrooms. The results of the study suggest that teacher education programs can help pre‐service teachers transition more smoothly into classroom teaching by providing a school–university partnership as well as more lessons and advice on handling specific classroom management situations. 相似文献

This study presents the results of an experiment which investigated analogical reasoning in knowledge acquisition in a natural school setting. The aims were to evaluate the efficiency of analogy in the conceptual restructuring of a science topic and compare the effects of analogy in different learning conditions. Two analogical topics of physics (water flow and heat flow) were studied by means of two experiments performed in the classroom with concrete objects. Eighty-four 5th graders, divided into three experimental conditions (given analogy, constructed analogy, no analogy), took part in the study. The quantitative analysis mainly confirms the hypothesis that analogy can be a productive way to trigger a process of knowledge restructuring while students learn a new topic. However, the effective use of the analogy was affected by the experimental condition: When the analogy was constructed by the learners themselves, instead of being presented and justified by the teacher, it acted indeed as a more powerful tool in understanding the new topic which required changing their initial conceptions. The qualitative analysis shows the children’s explanations of the heat flow phenomenon and different conceptual outcomes of the learning process. Finally, educational implications are considered. 相似文献

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

The synthesis of subject and pedagogy for effective learning and teaching in primary science education 总被引：1，自引：0，他引：1
《British Educational Research Journal》2004,30(6):819-839
The issue of science subject knowledge, and how to address the demands of this for both practising and trainee primary teachers, has constituted a core research enterprise in recent decades. The Professional Standards for Qualified Teacher Status entail considerable conceptual demands for many primary trainees. Generating meaningful causal explanations of scientific phenomena lies at the heart of both the scientific endeavour itself, and of effective classroom teaching. To focus on knowledge acquisition per se in teacher education, however, obscures the critical issue of subject‐related pedagogical knowledge that ultimately influences classroom practice. This article explores the development of both subject knowledge and subject‐related pedagogical knowledge in science education. It is informed by science education literature, as well as by a substantial body of empirical research into trainees' learning of aspects of physical science accumulated over a five‐year period. Learners' perspectives of the synthesis of subject and pedagogy raise important questions concerning the nature of teacher education. 相似文献

The purpose of this study was to explore whether conceptual change predicted emotional and attitudinal change while learning about genetically modified foods (GMFs). Participants were 322 college students; half read a refutation text designed to shift conceptual knowledge, emotions, and attitudes, while the other half served as a control group. The results suggest that the refutation text effectively facilitated change in conceptual knowledge, emotions, and attitudes. The hypothesized relationship among the variables was explored using structural equation modeling. The analysis showed that when participants experienced knowledge change toward more scientifically accepted conceptions of GMFs, their emotions became more positive and less negative, which predicted a subsequent shift toward more-positive attitudes. The results suggest that change in emotions mediates the relationship between conceptual and attitudinal change. Several theoretical and practical implications are discussed including the impact that these findings may have on science education. 相似文献

This paper, through discussion of a teaching intervention at two secondary schools in Hong Kong, demonstrates the learning advancement brought about by group work and dissects the facilitating role of teachers in collaborative discussions. One-hundred and fifty-two Secondary Two (Grade 8) students were divided into three pedagogical groups, namely ‘whole-class teaching’, ‘self-directed group work’ and ‘teacher-supported group work’ groups, and engaged in peer-review, team debate, group presentation and reflection tasks related to a junior secondary science topic (i.e. current electricity). Pre- and post-tests were performed to evaluate students’ scientific conceptions, alongside collected written responses and audio-recorded discussions. The results indicate that students achieved greater cognitive growth when they engaged in cooperative learning activities, the interactive and multi-sided argumentative nature of which is considered to apply particularly well to science education and Vygotsky’s zone of proximal development framework. Group work learning is also found to be most effective when teachers play a role in navigating students during the joint construction of conceptual knowledge. 相似文献

The purpose of this study was twofold. First, it was aimed to identify Turkish pre‐service physics teachers’ knowledge and understanding of the Moon, Moon phases, and other lunar phenomena. Second, the effects of model‐based teaching on pre‐service teachers’ conceptions were examined. Conceptions were proposed as mental models in this study. Four different questionnaires including 22 generative, explanation, and factual questions were used through the study. The pre‐service physics teachers’ mental models generated in response to lunar phenomena might be representations of their naïve knowledge as a result of their causal observations and experiences with the world, and their misconceptions as a result of inconsistencies between their naïve knowledge and scientific knowledge. Therefore, the pre‐service teachers’ mental models were categorized based on the work by Chi and Roscoe. Some of the pre‐service teachers’ mental models shifted from flawed or incomplete mental models to correct mental models of the Moon and lunar phenomena with the facilitation of model‐based teaching. The conclusions of the study carry implications for curriculum developers and teacher education. 相似文献

The aim of this study is to contribute to the innovation of pre‐vocational education, in particular, students' orientation at possible future occupations. From our theoretical understanding, vocational orientation that makes sense to students requires them to be part of a ‘community of learners for vocational orientation’. In such a community, students are stimulated to learn deliberately while participating in vocational practices. In this article we distinguish four parameters to define a community of learners for vocational orientation. We then present the results of a collective instrumental case study into teaching‐learning processes in four classes in two pre‐vocational secondary schools. Data were collected through classroom observations, a series of interviews with teachers and students. The interviews focused on eight ‘critical incidents’ recorded during classroom observations. The results show that the parameters ‘shared learning’ and ‘meaningful learning’ are more manifest in the teaching‐learning process than ‘reflective learning’ and ‘a focus on transferable learning outcomes’. The article concludes with a discussion of the limits of working in simulated work situations in school for realizing effective pre‐vocational education. 相似文献
