为了反映对学生在数学和科学方面的成就和参与的关注,STEM教育中的有效原则改进(epiSTEMe)项目试图支持这两个学科的教学进步。该项目利用研究文献中确定的有效原则(并以一种新颖的方式将这些原则结合起来),为英国早期中学教学开发了主题模块,安排在课堂上实施,并评估了结果。本文报道了epiSTEM数学模块的开发、实施和评估,该模块涵盖了与初中课程相关的有理数和比例推理方面,并与教师合作开发,在11个教室实施,并通过与16个对照教室的比较进行评估,其中16个教室使用既定的方法处理该主题。使用episTEM材料的学生在主题掌握方面比对照组学生取得了更大的进步,同时对他们的教学和学习经验持积极态度。
Reflecting concerns about student attainment and participation in mathematics and science, the Effecting Principled Improvement in STEM Education (epiSTEMe) project attempted to support pedagogical advancement in these two disciplines. Using principles identified as effective in the research literature (and combining these in a novel fashion), the project developed topic modules for early secondary-school teaching in the UK, arranged for their implementation in classrooms, and evaluated the results. This article reports the development, implementation and evaluation of theepiSTEMemathematics module entitledFractions, Ratios and Proportions.The module covers aspects of rational number and proportional reasoning relevant to the early secondary curriculum, and was developed in collaboration with teachers, implemented in 11 classrooms, and evaluated through comparison with 16 control classrooms where the topic was addressed using established methods. Students who used theepiSTEMematerials made significantly greater progress than control students as regards topic mastery, while holding positive opinions about their teaching and learning experiences.
