【摘要】 生物学是一门以实验为基础的自然科学,实验教学具有丰富的素质教育功能,要在中学生物教学中落实素质教育,生物实验教学是一个突破口。积极开展以实验为基础的教学活动,实施生物探究实验教学,本文以高中生物教学中“《绿叶中色素的提取和分离实验教学为例》”作为研究对象,通过此研究改进中学生物的实验课堂传统教师讲解,学生做验证性实验的教学方法,给学生提供充足的仪器和药品,让学生小组讨论,设计实验,描述现象,总结结论,让学生在生物实验中掌握生物学知识,从而达到充分利用实验,使每一个学生通过做实验都能看到自己在发展中的长处,增强继续学习的信心,激发学生的内驱力,调动学生的积极性和主动性;既培养学生小组合作精神,又培养学生分析问题、归纳问题、总结问题的能力。从根本上促进学生认知、能力、个性的发展,乃至完美人格的形成,为学生的终身学习奠定基础。同时使教师发现学生多方面的潜能,了解学生发展中的需求,通过不断优化教学方式和方法最终促进学生在知识与技能,过程与方法,情感态度与价值观方面的发展。本文首先综述了生物教育的发展过程及国内外现状,以及生物实验在基础生物教育中地位及作用,通过当前课程改革和当前生物实验课堂教学主要存在的5个问题提出本研究课题。在第二章中,本文具体论述了实验教学过程中所应用的三种理论,即建构主义、探究式学习和学生自主发展,重点对探究式学习进行了详细阐述。第三章对在绿叶中色素的提取和分离实验案例进行系统分析,通过详细设计教学过程,并通过精心设计的测试题对学生学习效果的进行有针对性的检测,基本达到了研究的目的。更多还原

【Abstract】 Biology is an experimental basis to the natural sciences, experimental teaching is rich in quality education functions, to teaching in secondary schools in the implementation of quality education, biological experiment teaching is a breakthrough. To actively carry out experiments based on the teaching and learning activities, the implementation of Inquiry experimental teaching, the paper in high school biology teaching "and" green pigment in the extraction and separation of teaching as an example "and" as a study, through the study of biological experiments to improve schools Teachers on the traditional classroom, students do experimental verification of the teaching methods, to provide students with adequate equipment and medicine to enable students to the panel discussion, design experiments, described the phenomenon, summary conclusions to enable students to master in biological experiments in biological knowledge to achieve Make full use of experiments, so that every student can see through their own experiments in the development of the strengths and enhance the confidence to continue learning and to stimulate students Neiqu Li, the mobilization of student enthusiasm and initiative, both groups of students cultivate a spirit of cooperation, And training students of the problem, summed up the problem, summed up problems. And fundamentally promote the awareness of students, ability, personality development, as well as the formation of a perfect personality for the students lay the foundation for lifelong learning. At the same time so that teachers found students with potential, to understand the needs of students in the development, through continuous optimization of ways and means of teaching students in the final promote knowledge and skills, processes and methods, emotional attitudes and values development.This paper reviewed the development of education process and the status quo at home and abroad, as well as biological experiments in the biological basis of the status and role of education, through the current curriculum reform and current biological experiments teaching the five main problems of the present study. In the second chapter, the paper specifically address the experimental process of teaching by the application of the three theories, that is, Constructivism, inquisitive learning and students for self-development, the focus of the inquiry carried out a detailed study on. Chapter III of the green pigment in the extraction and isolation of cases for analysis, through detailed design of the teaching process, and through carefully designed tests that the students study the effect of a targeted testing, reached a basic research purposes.更多还原
