【摘要】 论文进行了学习环运用于高中化学教学的研究。阐述了学习环作为简单有效探究教学模式的起源、阶段、类型、发展及其理论基础;梳理了学习环在国内外物理、化学、生物等学科教学中的一些案例;综述了学习环在科学教学中的应用情况。学习环主要用于概念的学习和教学,因此对苏州和无锡一千多名中学生的化学概念学习状况进行了调查。论文选取苏教版高中化学必修1专题一的第一单元进行学习环教学设计,并在中学实施了为期一个月的课堂教学实践。探究参与研究的学生化学概念学习方法的改变,“丰富多彩的化学物质”单元的概念掌握情况,参与研究的学生对学习环教学的反馈,合作教师对学习环教学的理解和看法,以及学习环教学中遇到的困难和应对策略。通过研究及反思,获得如下结论:1.通过对中学生化学概念学习现状的调查,获得的启示是,可以借助学习环用探究的方法学习化学概念,促进学生对化学概念的理解。2.通过一个月的学习环教学,学生习得化学概念的方法、保持化学概念的方法和应用化学概念的方法有提升,但是不显著。3.通过一个月的学习环教学,学生基本达到了江苏省普通高中化学课程标准的教学要求,尤其是对本单元的重难点掌握情况良好。4.学习环教学中大部分学生能够积极思考,敢于说出自己的想法,探究意识得到发展,但也有个别学生消极被动。5.学习环教学过程中受到教学时间、合作教师、参与研究的学生和实验条件等方面的限制。通过与合作教师的交流、讨论和协作,以及课前的充分准备,可以找到应对策略。更多还原

【Abstract】 In this paper, the learning cycle was used to teach chemistry in high school; the origin, phases, types, development and theoretical foundations of the learning cycle were discussed; some cases of learning cycle teaching were sumed up; the applications of learning cycle in science teaching were reviewed. The learning cycle is mainly used in concepts learning and teaching, so more than one thousand students were investigated, to seek the learning conditions of chemical concepts. Using learning cycle method, lesson plans were developed, and put into practice for one month.This research revealed:1. With the help of learning cycle, students can learn chemical concepts by inquiry approaches.2. The learning methods of students who participated in the research were improved, but no significant differences.3. The students who participated in the research basically met the teaching requirements, especially did well in the key points and the difficult points.4. The feedbacks of the students who participated in the research were pretty good, with one or two exceptions had some negative attitudes.5. The difficulties in learning cycle teaching included the teaching time and teaching progress, cooperative teacher’s understandings to learning cycle, the adjustment of students who participated in the research, and the shortages of experiment devices. Some suggestions were given to solve these difficulties.更多还原
