发布时间：2019-02-26 14:08
【摘要】：物理模型作为一种有效的教学手段和学习方式,在教学活动中取得的成效得到了教师的广泛认可,但在生物模型研究领域,涉及到学生如何更好地制作适合教学的物理模型以及学生自制物理模型对生物概念构建与掌握的研究还比较少。本文以高中生物必修一模块“分子与细胞”的部分内容为研究对象,以教育研究法对自制物理模型对高中生概念构建的情况进行了初步的研究与探讨。研究内容包括自制物理模型对学生学习积极性的影响,对学生参与度和动手能力的影响以及采用制作物理模型教学与常规教学对学生学习生物概念的差异。本研究以自制物理模型为自变量,以能够评价学生通过物理模型制作,体现学生概念掌握的成绩为因变量,实验班以学生自制物理模型为教和学的策略,对照班级则以讲授法为教与学的策略。根据学生的实际情况,围绕不同的认知目标水平进行物理模型的制作和概念构建的教学活动,并对两个班级的学生进行实验调查和访谈。结果初步显示,自作物理模型能够帮助学生构建知识结构,促进错误概念的转变,进一步提高学生的生物成绩。物理模型教学能有效地实现新课程的目标,并为学生学习生物以及其他学科提供必要的指导和帮助。
[Abstract]:As an effective teaching method and learning method, physical model has been widely recognized by teachers in teaching activities, but in the field of biological model research, There is little research on how to make the physics model suitable for teaching and how to construct and master the concept of biology by students' self-made physics model. In this paper, a part of "molecule and Cell", a required module of high school biology, is taken as the research object, and the self-made physical model is used to study and discuss the construction of the concept of senior high school students by means of educational research. The research contents include the influence of self-made physical model on students' learning enthusiasm, the influence on students' participation and hands-on ability, and the difference between making physics model teaching and routine teaching on students' learning biology concept. In this study, self-made physical model is used as independent variable to evaluate students' achievement in making physical model and reflect students' mastery of concept as dependent variable. The experimental class takes students' self-made physical model as teaching and learning strategy, and the experimental class takes self-made physical model as teaching and learning strategy. In contrast, the teaching method is the strategy of teaching and learning. According to the actual situation of students, the teaching activities of making physical models and constructing concepts around different levels of cognitive goals are carried out, and the students in two classes are investigated and interviewed by experiments. The results show that the self-made physical model can help students to construct knowledge structure, promote the transformation of erroneous concepts, and further improve the students' biological scores. Physics model teaching can effectively achieve the objectives of the new curriculum and provide the necessary guidance and help for students to study biology and other subjects.
