科学概念转变教学的新视野与新思路

New Vision and Approach for Conceptual Change in Science Teaching

长期以来，促进学生概念转变一直都是科学教育研究领域的重要课题，但传统的观念和教学策略背后 却存在着一些知识论的误区。2015年联合国教科文组织发布《反思教育：向“全球共同利益”的理念转变？》报告，引 领全球教育发展与变革的新航程，也拓宽了对知识概念的理解。《反思教育》中提出了新知识观，对人类的教育提 出了新的要求。概念转变教学中前概念的合理性和概念转变过程的多样性、复杂性和反复性，是教学实践中学生 概念转变困难的重要原因。新知识视野下，概念转变的教学目标应重新定位，重新确立“会教”和“学会”的标准，以 培养和提升学生的科学核心素养。

Fora long time， one of important issues of science education is to promote students’ con- ceptual change. However，there have been some misunderstandings on the conception of ^knowledge” and related epistemology in traditional concepts and teaching strategies. In 2015，UNESCO published a significant report Rethinking Education： Towards a Global Common Good？ This report has led a new way for the global education development and reform and elaborated a new vision of “knowledge”， put forward new requirements for human education. Based on this new vision of ^knowledge”，the rationality of the concept change and the diversity， complexity and repetition of the concept change process in teaching are important reasons for the difliculty of the student's concept transformation in teaching practice . From the perspective of new knowledge， the teaching goal of concept change should be repositioned， and the standards of “teaching” and “learning” should be re-established so as to cultivate and upgrade students' scientilic core qualities.
