“发现学习”理论的基本特点是:强调学习过程,强调学习者的内在动机,强调直觉思维,强调对信息的提取。依据“发现学习”理论和化学学科的特点,“发现学习”化学教学模式主要是在教师引导下,由学生主动探索发现和应用所学知识。“发现学习”化学教学模式符合科学发现的原过程及学生的认知规律,有利于学生对相关信息的组织与提取,对促进学生智力发展,增强思维能力,形成科学的世界观和方法论将产生深远影响;符合中学生的心理特点,能激发学生的探究欲望,为学生主动发展创造良好的条件;符合教师为主导,学生为主体的现代教学思想,学生通过主动参与而获得的知识,理解更深刻,掌握更牢固,运用更灵活,对发展个性,培养能力,造就创造型人才大有裨益。在运用这一教学模式时,要重视教学媒体的作用,尤其是实验和多媒体手段。
The basic characteristics of “discovery learning” theory are: emphasizing the learning process, emphasizing learners’ intrinsic motivation, emphasizing intuitive thinking and emphasizing the extraction of information. According to the theory of “Discovery Learning” and the characteristics of chemistry, the chemistry teaching mode of “Discovery Learning” is mainly explored and discovered and applied by students under the guidance of teachers. The discovery-learning chemistry teaching mode conforms to the original process of scientific discovery and the cognition of students, which is conducive to students ’organization and extraction of relevant information and will have far-reaching effects on promoting students’ intellectual development, enhancing their thinking ability and forming a scientific world outlook and methodology It is in line with the psychological characteristics of middle school students, can stimulate the desire of students to explore, and create favorable conditions for the students to take the initiative to develop. In line with the teacher-led, students as the main body of modern teaching ideas, students get through active participation of knowledge, more profound understanding, More solid grasp, the use of more flexible, on the development of personality, develop ability, create creative talents of great benefit. In the use of this teaching mode, we must pay attention to the role of teaching media, especially experimental and multimedia tools.
