高中化学必修1复习课的PBL应用研究
发布时间：2018-12-08 08:07
【摘要】：基于问题的学习(Problem-Based Learning,简称PBL)是一种以学生为中心、教师充当信息提供者、扮演辅助角色的教学模式,即通过教育者精心的设计,把学生要即将学到的知识置于复杂的、结构不良的实际生活情境中,以学生已经具备的多个领域学科知识为基础,以问题的解决为主线,学生通过合作与探讨的学习氛围中挖掘和构建隐含的知识。由于我国特殊的教育现状,高考成为我国教育的一大亮点,高中基础教育逐渐把莘莘学子转向分数的奴隶与考试的工具,海量的习题成为高中学生日常生活的“必需品”。随着新课程改革的到来,新授课的课堂也慢慢地发生着潜移默化的改变,可是相对新授课而言复习课教学模式的改变就显得微乎其微了,很多复习课的课堂是枯燥无味的习题课,不能很好激发学生学习兴趣。为了在教育方法上有所突破和创新,提高复习课的教学质量,本研究把PBL应用在高一化学必修1复习课的教学实践中,结合“铝及其重要化合物”的专题复习课为研究案例阐述PBL复习课的教学设计,最后通过问卷调查、访谈以及统计分析的方法探究PBL复习课对学生的影响。得到以下结论:PBL复习课对学生的成绩的提高较为显著。其次,在学习兴趣、获得知识的系统性、体验知识的适用性等方面,参与实验的大部分学生认为PBL复习课优越于传统课堂。
[Abstract]:Problem-based learning (PBL) is a student-centered teaching model in which teachers act as information providers and act as auxiliaries, that is, through careful design by educators. Placing the knowledge that students are about to learn in a complex, ill-structured real life situation, based on the knowledge of a number of disciplines that students already possess, and taking problem-solving as the main line. Students excavate and construct the implied knowledge in the learning atmosphere of cooperation and discussion. Because of the special educational situation in our country, the college entrance examination has become a bright spot in our country's education. The elementary education in senior high school has gradually turned the students into the slave of scores and the tool of examination, and the massive exercises have become the "necessity" of the daily life of the high school students. With the advent of the new curriculum reform, the new classroom teaching is slowly changing, but compared with the new teaching, the change of the teaching mode of the revision course appears to be very little. Many recitation classes are boring exercise classes, which can not well stimulate students' interest in learning. In order to make a breakthrough and innovation in the educational methods and improve the teaching quality of the revision course, this study applies PBL to the teaching practice of the required 1 chemistry review course in Senior one. This paper discusses the teaching design of PBL review class based on the special topic review class of "Aluminium and its important compounds". At last, it explores the influence of PBL review class on students by questionnaire, interview and statistical analysis. The following conclusions are drawn: the improvement of students' scores in PBL review class is significant. Secondly, most of the students involved in the experiment think that the PBL review class is superior to the traditional one in the aspects of learning interest, the systematization of acquiring knowledge and the applicability of experiential knowledge.
