【摘要】：新一轮的基础教育改革对我国基础教育影响深远,取得了卓越成效,但也表现出明显的地区差异。其中以笔者工作学校为典型的经济落后地区的普通高中教育存在两大弊端：一方面学生整体素质下降,无学习兴趣和团队合作意识；另一方面教师教学方法和手段落后。而基于问题的学习(PBL)对于培养学生的问题意识和探究精神能发挥显著作用,为普通高中的新课改提供了思路。本文通过简介PBL的理论知识,界定PBL的概念,分析PBL的基本特征,论证PBL是符合新课改理念的教学策略。在此基础上,阐明在生物课教学引入PBL的意义,尝试在高中生物新授课中进行教学实践,分析评价其教学效果,反思总结存在的问题,由此提出普通高中生物新授课开展PBL教学的建议。论文的实践研究部分以《细胞的物质输入和输出》单元的教学为案例,对PBL教学过程进行了展示,通过实践拟定开展PBL教学的操作程序。案例赋予学生治理盐碱地的农业专家角色,要求学生完成一份盐碱地治理方案；以此为基础开展PBL的合作学习,最后集中展示学生的学习成果。通过PBL学习,学生掌握了细胞的物质输入和输出的相关理论知识,而且能够灵活运用解决实际问题,发展了学生的创新思维和解决问题能力。最后通过对实践结果的分析,归纳实践研究结论与研究不足,提出优化PBL教学的建议。
[Abstract]:The new round of basic education reform has a profound impact on the basic education of our country, and has achieved remarkable results. However, there are also obvious regional differences. Among them, there are two drawbacks in the ordinary high school education in the economically backward areas, which are typical of the author's working school: on the one hand, the students' overall quality has declined, they have no interest in learning and their sense of teamwork; On the other hand, teachers' teaching methods and means are backward, and problem-based learning can play a significant role in cultivating students' awareness of problems and exploring spirit, which provides a way of thinking for the new curriculum reform in ordinary high schools. This paper introduces the theoretical knowledge of PBL. This paper defines the concept of PBL, analyzes the basic characteristics of PBL, and proves that PBL is a teaching strategy in accordance with the new curriculum reform idea. On this basis, it expounds the significance of introducing PBL into biology teaching, and attempts to carry out teaching practice in the new biology teaching in senior high school. This paper analyzes and evaluates its teaching effect, reflects on the existing problems, and puts forward some suggestions for developing PBL teaching in the new teaching of biology in senior high school. The practical research part of the thesis takes the teaching of "material input and output of cells" unit as a case study. The teaching process of PBL is demonstrated and the operating procedure of PBL teaching is drawn up through practice. The case gives students the role of agricultural experts in the treatment of saline-alkali land and requires students to complete a plan of saline-alkali land management. On this basis, the cooperative learning of PBL is carried out, and the final focus is on showing the students' learning results. Through the study of PBL, the students have mastered the relevant theoretical knowledge of the material input and output of the cells, and have been able to solve practical problems flexibly. Finally, through the analysis of the practical results, the author concludes the conclusions of the practical research and the insufficiency of the research, and puts forward some suggestions on how to optimize the PBL teaching.
