A professional learning program for teachers of junior secondary mathematics regarding the content and pedagogy of senior
secondary mathematics is the context for this study of teachers’ mathematical and pedagogical knowledge. The analysis of teachers’
reflections on their learning explored teachers’ understanding of mathematical connections and their appreciation of mathematical
structure. The findings indicate that a professional learning program about senior secondary mathematics can enable practicing
teachers to deepen and broaden their knowledge for teaching junior secondary mathematics and develop their practice to support
their students’ present and future learning of mathematics. Further research is needed about professional learning approaches
and tasks that may enable teachers to imbed and develop awareness of structure in their practice. 相似文献

In order to promote scientific inquiry in secondary schooling in Taiwan, the study developed a computer-based inquiry curriculum (including structured and guided inquiry units) and investigated how the curriculum influenced students’ science learning. The curriculum was implemented in 5 junior secondary schools in the context of a weeklong summer science course with 117 students. We first used a multi-level assessment approach to evaluate the students’ learning outcomes with the curriculum. Then, a path analysis approach was adopted for investigating at different assessment levels how the curriculum as a whole and how different types of inquiry units affected the students’ development of conceptual understandings and inquiry abilities. The results showed that the curriculum was effective in enhancing the students’ conceptual knowledge and inquiry abilities in the contexts of the six scientific topics. After the curriculum, they were able to construct interconnected scientific knowledge. The path diagrams suggested that, due to different instructional designs, the structured and guided inquiry units appeared to support the students’ learning of the topics in different ways. More importantly, they demonstrated graphically how the learning of content knowledge and inquiry ability mutually influenced one another and were reciprocally developed in a computer-based inquiry learning environment. 相似文献

In this study we created, implemented, and evaluated the impact of proportional reasoning authentic investigative tasks on
the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers.
For this purpose, a special teaching model was developed, implemented, and tested as part of the pre-service mathematics teacher
education programs conducted in Israeli teacher colleges. The conclusion of the study is that application of the model, through
which the pre-service teachers gain experience of and are exposed to authentic investigative proportional reasoning tasks
with incorporation of theory (reading and analyzing relevant research reports) and practice, leads to a significant positive
change in the pre-service teachers’ mathematical content and pedagogical knowledge. In addition, improvement occurred in their
attitudes and beliefs towards learning and teaching mathematics in general, and ratio and proportion in particular. 相似文献

This paper examines a problem described as widespread and long-standing in mathematics education: supporting pupils into multiplicative reasoning, a form of reasoning that has been noted as central to large tracts of secondary mathematics and beyond. Also noted, however, is a persistent perception of multiplicative situations only in terms of repeated addition – a perception held not only primary pupils, but also among primary teachers and curriculum developers. The focus of this paper is to synthesize literature on multiplicative reasoning as a conceptual field together with a sociocultural discussion of the role of mediating artifacts in the development of this conceptual field. Bringing MR into the primary classroom can then be achieved, I propose, through a pedagogy oriented toward model-eliciting and teacher appropriation of pupils’ models as pedagogic tools with the subsequent re-appropriation of refined models by pupils. This pedagogy is illustrated through the analysis of two vignettes from a teaching experiment which demonstrate the beginnings of MR as an emergent conceptual field in the classroom. The paper concludes that it is possible to move primary teaching and learning toward understanding the functional aspects of multiplicative reasoning, but that any such moves requires attention to teachers’ pedagogic and content knowledge. 相似文献

This paper reports a classroom observation study which intends to characterise the instructional practices in junior secondary mathematics classrooms in Beijing, Hong Kong and London, focusing on the different cultural beliefs pertaining to mathematics and mathematics teaching and learning between the Chinese and Western cultures. The results show that there are striking differences in classroom practices between the three places, and the differences seem to be related to the differences in attitudes towards mathematics and mathematics teaching and learning. The findings point to the potential of the cultural perspective in interpreting results of comparative curriculum studies. 相似文献

Mathematics teacher education aims to improve teachers’ use of mathematical knowledge to support teaching and learning, an aspect of pedagogical content knowledge (PCK). In this study, we interviewed teachers to understand how they used mathematics to make sense of student solutions to proportional reasoning problems. The larger purpose was to find accurate ways of categorizing teachers’ ability to do this vital aspect of teaching and thereby to inform assessment, teacher education, and professional development. We conjectured that teachers’ PCK for proportional reasoning could be reliably described in terms of attention to quantitative meanings in story problem contexts and in terms of understanding naïve forms of proportional reasoning. Instead, our findings reveal that individual teachers used a variety of means to make sense of (1) cognitively similar student solutions to different tasks and (2) mathematically related steps of a student solution within a single task. These findings illustrate the complexity of PCK for the topic of proportional reasoning and suggest the limits of what can be inferred about teacher knowledge from teachers’ evaluations of student solutions. We discuss implications for teacher education and assessment. 相似文献

Educative curricula, curriculum materials that intentionally foster teacher professional development, can serve as a site for teacher learning through their use in daily instructional practices. The present article introduces a framework, Teacher Learning Opportunities in Mathematics Curriculum Materials (TLO-Math), for designing and evaluating mathematics curriculum materials’ educative features according to seven theoretically based variables: (1) mathematics content knowledge for teaching, (2) teacher knowledge of student thinking in mathematics, (3) teacher knowledge of disciplinary discourse in mathematics, (4) teacher knowledge of assessment in mathematics, (5) teacher knowledge of differentiated instruction in mathematics, (6) teacher knowledge of technology use in mathematics, and (7) teacher knowledge of mathematical community. Each variable is illustrated with a definition, guiding questions, discipline-specific literature, and examples from two sets of elementary mathematics curriculum materials. The development of the TLO-Math framework is a critical first step for further study of the use of mathematics curriculum materials as sites for teacher learning. 相似文献

几何证明在本质上是一种方法论,学生学习欧氏几何、经过这种论证方法的训练是很有益处的。数学教学必须尊重学生身心发展的规律,有关逻辑推理的数学教学不能出现得太早。小学阶段主要是认同;初中阶段可以逐渐建立概念以及在此基础上的逻辑推理,但必须有物理背景;到了高中,才可以逐步渗透形式化的概念以及在此基础上的逻辑推理。过分强调演绎逻辑的数学教学,是不利于创新人才培养的。归纳推理有利于发现新的命题,是培养创新型人才所必需的。 相似文献

The aim of the study was to investigate progress in reasoning capacity and knowledge base appraisal in a longitudinal analysis of data from summative evaluation throughout a medical problem-based learning curriculum. The scores in multidisciplinary discussion of a clinical case and multiple choice questionnaires (MCQs) were studied longitudinally for 213 students from years 2 to 5. The capacity of core knowledge delimitation was calculated as the difference between the levels of average ascertainment degrees given for correct and incorrect answers at MCQ. For both multidisciplinary discussion of a clinical case evaluation and self-estimation of core knowledge, the capacity increases throughout the curriculum. The reasoning capacity assessed through multidisciplinary discussion of a clinical case is positively correlated with MCQ scores and the capacity to discriminate the mastered core knowledge. In conclusion, this study indicates that self-estimation of core knowledge is associated with an increase in reasoning performance through a well-organised knowledge base. Since that ability is related to success or failure, it is suggested that student awareness about delimitation of mastered core knowledge is considered as part of learning. 相似文献
