Opportunities for the Development of Geometrical Reasoning in Current Textbooks in the Uk and Japan

چکیده
Developing a good model of the school geometry curriculum continues to be one of the most important tasks in curricular design in mathematics. This paper reports on an initial analysis of current best-selling textbooks used in lower secondary schools in Japan and the UK (specifically England and Scotland). The analysis indicates that, following the specification of the mathematics curriculum in these countries, Japanese textbooks set out to develop students’ deductive reasoning skills through the explicit teaching of proof in geometry, whereas comparative UK textbooks tend, at this level, to concentrate on finding angles, measurement, drawing, and so on, coupled with a modicum of opportunities for conjecturing and inductive reasoning. The available research suggests that each approach has its own strengths and weaknesses. Finding ways of capitalising on the strengths and mitigating the weaknesses could prove helpful in formulating new curricular models and designing new student textbooks.

Interpretations of National Curricula: the case of geometry in Japan and the UK
This paper presents an analysis of how the geometry component of the National Curricula for mathematics in Japan and in one selected country of the UK, specifically Scotland, is interpreted by textbook writers. While, of course, textbooks are not the only critical influences on student learning, such texts, as analyses of data from the Trends in International Mathematics and Science Study (TIMS...
متن کاملComparison of Video-Assisted Thoracoscopic Surgery and Intrapleural Urokinase as an Initial Treatment for Parapneumonic Effusion and Thoracic Empyema
Introduction: The treatment of complicated parapneumonic effusion (PPE) and thoracic empyema (TE) is controversial; and the choice of treatment after confirming the failure of simple drainage remains unclear. The purpose of this study was to compare the outcomes of intrapleural urokinase (UK) administration and video-assisted thoracoscopic surgery (VATS) as initial treatment options for PPE and...
متن کاملReclaiming the Secular: Developing Dialogic Skills for a Post-Secular Society
This research paper addresses secularization from both political and religious perspectives. One of its manifestations in the political sphere is that of globalization that can lead to alienation within society; and in the United Kingdom this is exemplified by Brexit. Within the religious sphere secularization is usually couched in oppositional terms. This paper reclaims the original use ...
متن کاملUniversal Health Coverage and Primary Healthcare: Lessons From Japan; Comment on “Achieving Universal Health Coverage by Focusing on Primary Care in Japan: Lessons for Low- and Middle-Income Countries”
A recent editorial by Naoki Ikegami has proposed three key lessons from Japan’s experience of achieving virtually universal coverage with primary healthcare services: the need to integrate the existing providers of primary healthcare services into the organised health system; the need to limit government commitments to finance hospital services and the need to empower providers of primary healt...
متن کامل“Seeing” the Difference: The Importance of Visibility and Action as a Mark of “Authenticity” in Co-production; Comment on “Collaboration and Co-production of Knowledge in Healthcare: Opportunities and Challenges”
The Rycroft-Malone paper states that co-production relies on ‘authentic’ collaboration as a context for action. Our commentary supports and extends this assertion. We suggest that ‘authentic’ co-production involves processes where participants can ‘see’ the difference that they have made within the project and beyond. We provide examples including: the use of design in health projects which see...
