信息技术支持下的学科教学知识:缘起、演化、结构模型及其教育意蕴

信息技术支持下的学科教学知识(TPACK)是学科教学知识(PCK)在信息化时代的发展。技术知识(TK)、教法知识(PK)和内容知识(CK)是TPACK结构模型中的基础成分;学科教学知识(PCK)、技术支持下的内容知识(TCK)、技术支持下的教学知识(TPK)和技术支持下的学科教学知识(TPACK)是TPACK结构模型中的互动成份。TPACK框架在理论上、在教师教育、在教学实践上等诸方面为信息技术与学科课程整合提供了新思路,将有助于我们推动学科教学知识发展,将为学科教育的信息化提供有力的教学知识基础。     

Pedagogical content knowledge of experts and novices—what knowledge do they activate when analyzing science lessons?

In the current debate on pedagogical content knowledge (PCK), the term is used to refer to the context‐specific knowledge that teachers activate when reflecting on practice. Against the background of this debate, we conducted an empirical study and sought to answer the question of which knowledge experts and novices activated in assessing a videotaped lesson in relation to its effectiveness for learning. Our assumption was that the participants activate their PCK as a blending of content knowledge (CK) and pedagogical knowledge (PK) as suggested by Shulman's amalgam thesis. The participants (9 experts and 9 novices) were shown a lesson on optics, in which the law of refraction (Snell's law) was being studied. In a subsequent interview, the participants were asked to analyze the observed lesson. A qualitative and quantitative evaluation of the interviews showed that experts activated both CK and PK intensively and in this respect they differed significantly from novices. Further analysis of the expert statements also proved that they do not activate their CK and PK in isolation, but instead combine both kinds of knowledge together, in line with Shulman's amalgam thesis. © 2017 Wiley Periodicals, Inc.

The Accuracy of Students’ Judgments of Their Teacher’s Opinions

Monte Carlo methods were employed to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. Sampling error influences were investigated across variations in variable and sample sizes, across variations in average within-set correlation sizes, and in across-set population correlation sizes. Sixty-four different research situations were investigated, and for each situation 1,000 random samples were drawn. Results suggest that both sets of coefficients are roughly equally influenced by sampling error, except perhaps when some intradomain correlation coefficients are quite large. Thus, the case for emphasizing interpretation of structure coefficients must be made on a psychometric basis rather than on the grounds that structure coefficients are less sensitive to sampling error influences, notwithstanding the positions previously taken by some theorists.

The Development of Diploma in Education Student Teachers’ Mathematics Pedagogical Content Knowledge

Mathematics pedagogical content knowledge (MPCK) of teachers cannot be easily defined but is a complex concept integrating generic pedagogical knowledge, mathematics teaching methodology as well as knowledge of the discipline of mathematics. It is the objective of mathematics methodology courses in teacher preparation programmes to begin the development of MPCK in their pre-service teachers. As part of a research study on the development of MPCK in primary school beginning teachers, a 16-item instrument was developed to measure some aspects of the MPCK for teaching mathematics at primary level. The instrument was administered to the 2003 Intake of the Diploma in Education student teachers at the National Institute of Education, Singapore just at the beginning of their programme. As they completed their methodology course in February 2005, the instrument was administered again. This paper will discuss the findings concerning their performance in these two tests, with reference to the overall performance as well as topic-specific and MPCK construct-specific performance. The findings indicate that student teachers at the beginning of their programmes are generally quite weak in their mathematics pedagogical content knowledge, as might be expected. There was significant improvement in some aspects of their MPCK on completion of their mathematics pedagogy course.     

The value of CK,PK, and PCK in professional development programs predicted by the progressive beliefs of elementary school teachers

Teachers’ professional development (PD) receives a great deal of attention in current educational settings. However, research has shown that many teachers hesitate to attend PD programs. In this study, data were collected from 270 elementary school teachers and were subjected to confirmatory factor analysis and structural equation modeling to examine their intention to attend the weekly PD programs on Wednesday afternoons (PDWAP). The results revealed that the participants value the acquisition of pedagogical content knowledge (PCK) more than they value pedagogical knowledge (PK) and content knowledge (CK) because of the expected usefulness of each for teaching. Moreover, the results of this study have implications for PD program design, and call for a stronger focus on PCK.

Para‐teacher scheme and quality education for all in India: policy perspectives and challenges for school effectiveness

This paper argues that the concepts, beliefs and understandings of local and non‐local teacher educators in a Hong Kong university are grounded in their own cultural cognition and antecedents. It presents the viewpoint that contemporary notions of good practice were compromised when applied to a context that is strongly influenced by the tenets of Confucianism. Thus the conclusion is that the contingencies of teaching and learning contexts are sufficiently different to compromise the goal of having pre‐constructed notions of good teaching. The alternative is that university tutors and future researchers re‐conceptualise good teaching practices within a context that gives it meaning and purpose.     

Prospective teachers' initial conceptions about pupils' understanding of science and mathematics

Earlier reports have shown that prospective teachers' conceptions about teaching science to a high degree are resistant and do not change substantially during the teacher‐training programme. In our investigation we elucidate the prospective teachers' initial conceptions about pupils' understanding of science and mathematics. We applied ‘The Lesson Preparation Method' and used a phenomenographic approach in order to reveal the range of conceptions that the prospective teachers hold. A third of the prospective teachers did not consider pupils' conceptions when planning lessons. The rest of the 32 participants expressed awareness; some of the prospective teachers even referred to subject‐specific teaching experience. Also regarding the prospective teachers' conceptions about pupils' knowledge and beliefs, as well as about pupils' difficulties, there was a significant diversity. By raising these issues about pedagogical content knowledge the prospective teachers' conceptions can be extended and developed during the education.

中学数学教师的教师知识来源的调查研究

本研究通过问卷调查了不同来源对中学数学教师的教师知识发展的重要程度。研究结果显示:自身教学经验与反思、和同事的日常交流是最为重要的职后的教师知识来源,而入职后的学历教育是最不重要的教师知识来源。在职前的各种教师知识来源中,教育见习实习、微格教学是职前比较重要的教师知识来源,而数学专业课、教育类课程是最不重要和次重要的教师知识来源。根据这些结果,我们提出了在教师教育中促进教师知识发展的建议。     

教师学科教学知识演变:内涵、特征及趋势

自舒尔曼提出学科教学知识(PCK)概念伊始,教师学科教学知识的演化已经走过三十余年。审视过去,学科教学知识结构中新元素的融入、学科化的探讨、层级化的审视以及智能化的思虑,促使了教师学科教学知识发展由点到面、由表及里、由浅至深。当前教师学科教学知识演化存在四种发展趋势:教师学科教学知识呈现博约合一的融合状态、教师师学科教学知识关注教育实践的相互嵌合、教师师学科教学知识重视教育情境的内生反思、教师师学科教学知识存在发展革新的时代审视。这些趋势促使了教师师学科教学知识研究国际化、境脉化、多样化的发展。今后,教师学科教学知识需要基于数据技术驱动做出变革:使用数据密集型科学范式革新教师的知识结构、在教师原有学科教学知识体系中嵌合数据素养、关注教育实践中数据驱动的教师反思和规律总结,以此促进智能教育时代教师的专业发展。     

Probing the amalgam: the relationship between science teachers’ content,pedagogical and pedagogical content knowledge

ABSTRACT

This Special Issue aims to present evidence about the relationships between content knowledge (CK), pedagogical knowledge (PK) and pedagogical content knowledge (PCK); the development of these types of knowledge in novice and experienced secondary science teachers; and how CK, PK and/or PCK impact students’ learning. Since Shulman’s introduction of PCK as the feature that distinguishes the teacher from the content expert, researchers have attempted to understand, delineate, assess and/or develop the construct in pre- and in-service teachers. Accordingly, empirical findings are presented that permit further discussion. Outcomes permit post-hoc examination of a recent, collectively described, ‘consensus’ model of PCK, identifying strengths and potential issues. As we will illustrate, the relationship between CK, PK and PCK is central to this; that is, probing the hypothesis of pedagogical content knowledge as an ‘amalgam’ of content and pedagogical knowledge.
