In this study, five elementary teachers and a university researcher developed and implemented problem‐based learning (PBL) experiences in the context of science teaching and learning. Collaborative inquiry was adopted as a methodology, while a variety of qualitative methods were used to examine the engagement and development of teachers’ pedagogical content knowledge (PCK). A PCK model is used as a framework to examine teachers’ professional knowledge growth in areas such as orientations to teaching science, knowledge of science curriculum, knowledge of students’ understanding of science, knowledge of assessment, and knowledge of instructional strategies. Implications for how teachers may be supported when adopting instructional innovations are discussed.  相似文献

A concept map is a schematic device for representing a set of concept meanings embedded in a framework of propositions. It can be used to evaluate students’ knowledge structure. This article introduces the comparative study of Chinese and American secondary school students’ knowledge structure. They are compared quantitatively and qualitatively in terms of mean score, individual proposition scores, proposition choice and map structure. The results indicate that students’ knowledge structures in the two countries are remarkably different. Compared with American students, Chinese students’ ability to take an exam is stronger and their mean score is higher. However, Chinese students need to improve their general knowledge and creativity although their basic knowledge is solid and they are better in mastering discipline knowledge and knowledge application.  相似文献

The present article extends Basil Bernstein’s theorisation of ‘discourses’ and ‘knowledge structures’ to explore the potential of educational knowledge structures to enable or constrain cumulative learning, where students can transfer knowledge across contexts and build knowledge over time. It offers a means of overcoming dichotomies in Bernstein’s model by conceptualising knowledge in terms of legitimation codes (bases of achievement) and semantic gravity (context‐dependency of knowledge). This developed framework is used to analyse two contrasting examples of curriculum – from professional education at university and secondary school English – that aim to enable cumulative learning. Analyses of students’ work products show that both cases can constrain knowledge‐building by anchoring meaning within its context of acquisition. The basis for this potential is located in a mismatch between their aims of enabling students to learn higher‐order principles and their curricular means that focus on knowers’ dispositions rather than articulating principles of knowledge.  相似文献

科学写作是将学生的科学理解和科学思维过程具体化为外在表征的过程,对学生的科学学习具有重要价值。知识转换模型作为解释学生科学写作心理过程的理论框架,有效揭示了写作促进学生学习的认知过程。与知识陈述模型相比,基于知识转换模型的科学写作更有助于促进学生生成与建构新知识,凸显学生的科学思维和科学理解。基于知识转换模型的科学写作需要教师明确科学写作目的,以合作者身份参与学生写作;引导学生设定科学写作目标,形成任务的心理表征;指导学生在科学写作的体裁与功能之间建立联系,激活问题空间;为学生设计多样化的作品读者,推动知识转换的进程;重视对学生科学写作过程的评价。  相似文献

The research reported here focuses on grade 7 (12‐year‐old) students’ epistomological views prior to and after exposure to a teaching unit especially developed to introduce the constructivist view of science. A clinical interview was used to assess students’ understanding about the nature of scientific knowledge and inquiry. Students’ initial epistemological stance is that scientific knowledge is a passively acquired, faithful copy of the world, and that scientific inquiry is limited solely to observing rather than constructing explanations about nature. We found that it is possible to move students beyond this initial view.  相似文献

A crucial skill for researchers in inter- and transdisciplinary environmental projects is the ability to be reflexive about knowledge and knowledge production. Few studies exist on the operationalization of reflexive skills and teaching and learning strategies that help students master these skills. This research aims to contribute in this direction. We distinguished two components of reflexive skills: (i) assessing the relative contributions of scientific disciplines and non-academic knowledge in addressing environmental issues; (ii) assessing the role of norms and values in research. We developed a framework for teaching and learning reflexive skills and evaluated this framework within a quasi-experimental educational setting involving 3 groups of 30 students. Students’ reflexive skills were assessed quantitatively using a pre- and post-test questionnaire. Moreover, students’ reflection papers were analysed to get a better understanding of their perspectives on the teaching and learning framework. We show that it is possible to train students in reflexive skills, but it requires a well-designed learning setting.  相似文献

Students’ vocational knowledge can be defined as all knowledge students require performing within occupational practice. In the context of vocational education and training, students’ vocational knowledge is often discussed from a perspective of either what should be taught and learned in schools or different kinds of knowledge students should gain in occupational practice. Much less focus is on students’ vocational knowledge itself. This exploratory in-depth study aims to describe what characterises students’ vocational knowledge. To explore students’ vocational knowledge, an analytic framework is used to describe vocational knowledge characteristics specifying: (1) occupation-specific knowledge components, and (2) qualities. Results show the framework provides a structure to gain insight into the nature and meaning of vocational knowledge, and is valuable to describe characteristics in terms of knowledge components such as technical procedures or the social and occupational environment, and qualities such as richness, complexity and specificity. Additionally, to use an existing framework – originally developed in the contexts of ICT and Social Work – its usefulness is explored in a new context, namely, the hospitality industry. Recommendations about the framework serving as a potential tool to support students’ learning processes are provided.  相似文献

Meaning-making and sense-making are generally assumed to be part of students’ personal vocational knowledge development, since they contribute to both students’ socialisation in a vocation and students’ personalisation of concepts, values and beliefs regarding that vocation. However, how students in vocational education acquire meaning and make sense of vocational knowledge is not explained. Furthermore, examples of what these processes entail in the context of vocational education are lacking. A multiple case study was performed to explore students’ meaning-making and sense-making in classroom interactions in Dutch senior secondary vocational education. Our results show that meaning-making is a process in which students interpret vocational knowledge by explicating and clarifying this knowledge. Sense-making is perceived to be a process in which students concretise vocational knowledge by testing and justifying this knowledge. A research model was developed to describe how students make meaning and sense of vocational knowledge in interaction with practitioners.  相似文献

A key educational objective for the twenty-first century is developing students’ epistemic agency. Epistemic agency is the active process of choosing when, what, where one learns and how one knows, as well as the capacity to create knowledge in a community. The knowledge-building communities model developed by Scardamalia and Bereiter was used in a New Zealand Year 13 distance art history class to support the development of students’ epistemic agency in 2013. In this study, students were given more control in the learning process, and were able to exercise epistemic agency through identifying their knowledge gaps, sharing information and ideas, developing ideas and creating communal knowledge. A number of factors that increased students’ development of epistemic agency are also discussed in this article.  相似文献

Instructional practice plays a significant role in understanding teachers’ pedagogical content knowledge (PCK). The aim of the study reported on was to compare mathematics and technology pre-service teachers’ knowledge of PCK. The study used a case study approach of five mathematics and five technology pre-service teachers with a total of ten. Data was collected in seven public schools around Gauteng province in South Africa. The observation technique was employed in order to understand students’ classroom practice, using a video camera to capture the setting. One lesson of 45 minutes presented by each pre-service teacher, rendering a total of ten lessons, was observed. The study adapted the theoretical framework of PCK (Shulman 1987). The study scrutinised the data based on the qualitative content analysis method and found that most pre-service teachers in both mathematics and technology possess a limited knowledge of PCK. In both subjects, most of the pre-service teachers’ classroom practice did not exhibit comprehensive knowledge of the subject matter or knowledge of the learners. However, the difference is that only mathematics pre-service teachers have some knowledge of assessment. The data also indicate that “9E” instructional practice can be a valuable tool to enhance field-specific PCK within the field of mathematics and technology education subjects. Therefore, the study proposes further investigation of the “9E” instructional model that could be used as field-specific PCK within the fields of mathematics, science and technology.  相似文献

This study aimed to explore how vocational high school students transfer knowledge through a problem-based learning (PBL) Internet platform. A PBL Internet platform was provided to 33 sophomore mechanical engineering students for a 6-week teaching experiment. A survey questionnaire, observation and interview were research instruments. The findings include: 1) factual, conceptual and process knowledge are the major types of knowledge and the sources of knowledge transfer (KT) include students, instructors and industries, but may be acquired differently depending on the level of problem-solving needs; 2) students’ KT includes highly experienced tacit knowledge and more concrete explicit knowledge; 3) students’ attitudes toward the six domains of using the PBL Internet platform all show positive significance, including the platform, the platform instructors, the platform mobility, online interaction, the PBL and the platform interface mechanism of students’ perceptions; 4) the capability and the willingness for KT in instructors, industries and students all have some impact on the effectiveness of KT.  相似文献

Background: Teacher knowledge continues to be a topic of debate in Australasia and in other parts of the world. There have been many attempts by mathematics educators and researchers to define the knowledge needed by teachers to teach mathematics effectively. A plethora of terms, such as mathematical content knowledge, pedagogical content knowledge, horizon content knowledge and specialised content knowledge, have been used to describe aspects of such knowledge.

Purpose: This paper proposes a model for teacher knowledge in mathematics that embraces and develops aspects of earlier models. It focuses on the notions of contingent knowledge and the connectedness of ‘big ideas’ of mathematics to enact what is described as ‘powerful teaching’. It involves the teacher’s ability to set up and provoke contingent moments to extend children’s mathematical horizons. The model proposed here considers the various cognitive and affective components and domains that teachers may require to enact ‘powerful teaching’. The intention is to validate the proposed model empirically during a future stage of research.

Sources of evidence: Contingency is described in Rowland’s Knowledge Quartet as the ability to respond to children’s questions, misconceptions and actions and to be able to deviate from a teaching plan as needed. The notion of ‘horizon content knowledge’ (Ball et al.) is a key aspect of the proposed model and has provoked a discussion in this article about students’ mathematical horizons and what these might comprise. Together with a deep mathematical content knowledge and a sensibility for students and their mathematical horizons, these ideas form the foundations of the proposed model.

Main argument: It follows that a deeper level of knowledge might enable a teacher to respond better and to plan and anticipate contingent moments. By taking this further and considering teacher knowledge as ‘dynamic’, this paper suggests that instead of responding to contingent events, ‘powerful teaching’ is about provoking contingent events. This necessarily requires a broad, connected content knowledge based on ‘big mathematical ideas’, a sound knowledge of pedagogies and an understanding of common misconceptions in order to be able to engineer contingent moments.

Conclusions: In order to place genuine problem-solving at the heart of learning, this paper argues for the idea of planning for contingent events, provoking them and ‘setting them up’. The proposed model attempts to represent that process. It is anticipated that the new model will become the framework for an empirical research project, as it undergoes a validation process involving a sample of primary teachers.  相似文献

This paper seeks to introduce a wider audience to a set of ideas developed by a group of sociologists of education who draw on Basil Bernstein’s late work on knowledge structures and whose epistemological stance is grounded in Social Realism. The paper’s main substantive focus is the concept of ‘powerful knowledge’ – recently popularised by Michael Young – and the implications of this notion for curriculum change. ‘Powerful knowledge’ connects with two other key ideas – ‘knowledge of the powerful’ and ‘esoteric knowledge’ – all of which have fed into recent debates about curriculum development and change. Various inter-connections between these ideas are examined. The paper concludes by identifying three chronic ‘tensions’ which impede efforts to extend powerful knowledge to socially and economically disadvantaged students.  相似文献

借鉴Kahan等的教学过程和基本要素研究框架,以情意原理、序进原理和活动原理作为解析课堂教学的框架,调查师范生融合内容的教学知识的实然水平。师范生的教学水平大致分布在三个等级上,师范生对学与教的理解有明显的缺失。如果师范生对知识的发生发展过程认识较为深刻,那么知识教学的序列安排就与知识发生的历史过程拟合得较好;如果师范生对做数学的一般机制有一定的体会,那么学生思维过程的设计就与历史上人们做数学的活动经验较为相似。数学发生发展的知识是影响师范生课堂教学水平的重要因素之一。  相似文献

Our paper builds on the construct of the zone of proximal development (ZPD) (Vygotsky in Mind in society: the development of higher psychological processes, Harvard University Press, Cambridge, 1978) to analyze the relationship between students’ answers and the help they receive as they construct them. We report on a secondary analysis of classroom and interview data that was collected with 1st and 2nd grade students completing a short scaffolded inquiry project designed to help them learn about how honeybees collect nectar. We explore how the progression of questions reveal students’ understanding of complex systems by examining how students’ progression through the questions tended to become more sophisticated as we increased support. We further compare two complex-systems perspectives, Component-Mechanism-Phenomena and agent-based approaches, to see how each would categorize students’ explanations. Findings demonstrate the value of the ZPD as an analytic framework in exploring students’ systems understanding in terms of the nature of questions (e.g., sequencing, type of question) and multiple conceptual models (e.g., component-mechanisms-phenomenon, single agent or aggregate behaviors), and how this might impact students’ groupings according to their ability and subsequent instructional support.  相似文献

As society becomes increasingly digital, teachers must be trained to integrate technology effectively into their classrooms. Teachers’ technological pedagogical knowledge (TPK), as defined in the TPACK framework, is considered an important prerequisite for effectively integrating technology. The TPACK framework has received a great deal of attention, yet few knowledge tests have been developed that directly assess TPK. However, those tests are crucial for evaluating the effectiveness of teacher education courses on technology integration. We have developed a 17-item test that covers teacher knowledge about various digital technologies as employed in teaching. Experts rated the items to represent the construct adequately. Data obtained from 245 pre-service teachers supports the test’s internal structure. Concerning convergent and discriminant validity, the pre-service teachers’ test scores were not related to their self-reported TPK, but to their self-reported technological knowledge. The test was sensitive to changes in pre-service teachers’ TPK through teacher education courses.  相似文献

This study presents a qualitative research based on three narratives written by novice mathematics teachers. We examine their unique professional world during their first year of work. The methodology of narrative framework, on which this article is based, helps to gain better understanding of the need for novice mathematics teachers to have pedagogical knowledge. Findings reveal three themes of pedagogical knowledge: the attitude of novice teachers toward students with difficulties in mathematics; parents’ expectations of and involvement with novice mathematics teachers; teacher–student relations. The implications of the findings show that novice mathematics teachers are required to have not only content knowledge of mathematics but also, and above all, pedagogical knowledge. The implications of this study enable reassessment of emphases required in training mathematics teachers, as well as the assistance and support they need, especially as they launch their careers.  相似文献

Dissertations are positioned as the capstone of an undergraduate degree, bringing together what students have previously learned from their programmes through a piece of independent research. However, there is limited research into the ways in which engaging in a dissertation has an impact on students’ understandings of disciplinary knowledge. In this article, we explore the relations between students’ accounts of sociological knowledge in their second and third years and how they engage with sociological knowledge in their dissertations. We argue that for the work of the dissertation to have an impact on students’ understanding of sociological knowledge, students need to see their discipline as providing a way of answering their research questions. We explore the implications of this argument for both our understanding of the role of dissertations and research-based learning in universities more generally.  相似文献

Abstract

Although native family students often learn more than immigrant family students in school (e.g. civics), scholars have not systematically demonstrated the mechanisms through which native family students outperform immigrant family students. The Opportunity-Propensity framework guides this study. We examine the link between students’ immigrant status and civic knowledge, with antecedent factors (socioeconomic status [SES] and language spoken at home), opportunity factors (civic learning at school, civic participation at school, and political discussion), and propensity factors (perceived open classroom climate and student-teacher relationship). Two-level path analysis of the responses to the International Civic and Citizenship Education Study (ICCS) 2016 by 6254 eighth graders in Denmark showed that the civic knowledge of native family students exceeded that of immigrant family students, mediated by their own and schoolmates’ higher family SES. Meanwhile, immigrant family students had more political discussions, which are linked to better civic knowledge.  相似文献

ABSTRACT

Systems’ thinking has become increasingly relevant not only in education for sustainable development but also in everyday life. Even if teachers know the dynamics and complexity of living systems in biology and geography, they might not be able to effectively explain it to students. Teachers need an understanding of systems and their behaviour (content knowledge), and they also need to know how systems thinking can be fostered in students (pedagogical content knowledge (PCK)). But the effective development of teachers’ professional knowledge in teaching systems thinking is empirically uncertain. From a larger study (SysThema) that investigated teaching systems thinking, this article reports the effects of the three different interventions (technical course, didactic course and mixed course) in student teachers’ PCK for teaching systems thinking. The results show that student teachers’ PCK for teaching systems thinking can be promoted in teacher education. The conclusion to be drawn from our findings is that a technically orientated course without didactical aspects seems to be less effective in fostering student teachers’ PCK for teaching systems thinking. The results inform educators in enhancing curricula of future academic track and non-academic track teacher education.  相似文献
