高中生物学凸显核心概念的教学现状及教学实践研究
发布时间：2018-08-22 20:23
【摘要】：生物学核心概念教学正在逐步走进我们的课堂。纵观高中生物学新课程理念的发展动态,不难发现核心概念教学有着不可替代的地位。在过去的十几年间,国际上的科学教育研究取得丰硕成果。美国先后于2012年和2013年正式发布了《K-12科学教育框架：实践、跨学科概念、核心概念》和《新一代科学教育标准》两份科学教育改革的重要文件,标志着21世纪新一波科学教育改革浪潮的到来。这两份纲领性文件充分展现了核心概念在学习内容中的价值,同时对我国生物学科凸显核心概念的教学起到催化作用。生物学核心概念教学关注点在学生,与传统的教学相比主要存在以下几方面优势：有效帮助学生提升探究思维能力；有效帮助学生理解事实和现象；有效帮助学生在头脑中构建知识框架,便于长久记忆知识。关于核心概念教学研究,与国外教育发达国家相比,我国在这方面相关的研究较晚,但所取得的成绩仍不可小觑。单从生物学科来看,很多的观点具有创新性。但对核心概念教学的实际效果和优缺点方面的实证研究却很少,亟待进一步提高研究力度和深度。通过进行问卷调查发现教师的整体素质有所提高,比如在教学方法方面,更多的教师不再是简单的直接给出生物学概念,而是能采用联系生活、类比推理、复习旧知等学生易于接受的方法传授概念；再者教师在生物学核心概念教学培养方向上,已经不再是单纯的知识记忆,更加重视学生思维推理等能力的培养,这些生物教师表现出来的教学观念和行为的进步,展现了我们教师队伍的生机和活力。在调查中还发现学生对生物学核心概念教学方面存在诸多困惑和阻碍。主要表现在学生的自我效能感偏低；学生对生物学核心概念重要性的认识程度不足；学生整体上缺乏科学合理的生物学概念学习方法。在就需要我们生物教师积极完善自己的教学,解决好与学生的教育教学矛盾。调查生物学核心概念教学现状并不是这次研究的主要目的,凸显生物学核心概念教学的优势和影响力才是本次研究的关键部分。所以有必要通过进行生物学核心概念教学实践的实验对比研究分析,给一线教育工作者带来一定的启发和指导,使核心概念教学能真正走进我们的课堂,并发挥应有的良好效应,真正能够提高课堂教学质量和效果。本研究以大量相关理论为基础,对生物学核心概念教学的实际效果从不同尺度进行分析研究,为生物学教学实践提供一手资料。
[Abstract]:The teaching of the core concept of biology is entering our classroom step by step. It is not difficult to find that the teaching of core concepts has an irreplaceable position throughout the development of the new curriculum concept of biology in senior high school. In the past ten years, the international scientific education research has made a lot of achievements. In 2012 and 2013, the United States issued two important documents on the reform of science education: the Framework of Science Education: practice, Interdisciplinary concept, Core concept and the Standards of Science Education of the New Generation. It marks the arrival of a new wave of scientific education reform in the 21 st century. These two programmatic documents fully demonstrate the value of the core concepts in the learning content and play a catalytic role in the teaching of highlighting the core concepts in biology in China. The teaching of biological core concepts focuses on students. Compared with traditional teaching, it has the following advantages: effectively helping students to improve their thinking ability of inquiry, effectively helping students to understand facts and phenomena; Effectively help students to build a knowledge framework in their minds, facilitate long-term memory of knowledge. Compared with the developed countries, the research on core concept teaching in our country is relatively late, but the achievements can not be underestimated. From a biological perspective alone, many ideas are innovative. However, there are few empirical studies on the practical effect, advantages and disadvantages of the core concept teaching, and it is urgent to improve the research intensity and depth. Through the questionnaire survey, we found that the overall quality of teachers has been improved, for example, in the teaching method, more teachers are no longer simply give the biological concept directly, but can use the link life, analogy reasoning, In addition, teachers are no longer pure knowledge and memory, and pay more attention to the cultivation of students' ability of thinking and reasoning. These biology teachers show the progress of teaching concept and behavior, showing the vitality and vitality of our teaching team. It is also found that there are many puzzles and obstacles in the teaching of biological core concepts. It is mainly reflected in the low sense of self-efficacy, the insufficient understanding of the importance of the core concepts of biology, and the lack of scientific and reasonable methods of learning biological concepts as a whole. We need biology teachers to improve their own teaching and solve the teaching contradictions with students. It is not the main purpose of this study to investigate the present situation of the teaching of the core concepts of biology, but to highlight the advantages and influence of the teaching of the core concepts of biology is the key part of this study. So it is necessary to carry on the experiment contrast research and analysis of the teaching practice of the biological core concept, bring some inspiration and guidance to the front-line educators, so that the core concept teaching can really come into our classroom. And play due good effect, can really improve the quality and effect of classroom teaching. Based on a large number of relevant theories, this study analyzes and studies the practical effects of teaching biological core concepts from different scales, and provides primary information for biology teaching practice.
