【摘要】：在社会文明快速发展的当下,科学能力成为科学社会衡量人才的重要标准之一。科学能力不仅包括科学知识的掌握,而且包括科学能力的培养。科学能力对于个人发展影响更为久远,然而科学能力集中体现为探究能力。探究能力不是与生俱来的,学习者可以通过经历发现、构想、抉择、归纳和评价等具有探究特征的学习过程,来提升和发展探究能力。本文研究旨在以探究能力培养为价值取向,设计在电子书包环境支撑下的初中化学实验探究教学模式。首先,针对电子书包、初中化学实验、探究学习和教学模式等基础性概念进行厘清,并对探究学习理论、建构主义学习理论、人本主义学习理论、信息技术与课程整合理论以及初中化学新课程标准进行分析。然后,选定问卷和访谈的调查方法,对吉林省长春市某中学的部分教师和学生进行现状调研并进行数据统计分析,总结发现化学实验课教学主要关注公式讲解,很少涉及学生探究能力的培养、学生使用电子书包的兴趣浓厚、传统教学模式不适应课堂教学等问题。然后,在智慧教育理念指导下,构建了电子书包环境下的探究教学模式,进而依据初中化学实验探究学习特征对该模式进行变式,最终提出电子书包环境下的初中化学实验探究教学模式。最后,以《实验室制取二氧化碳气体》为例应用模式,分析该模式的有效性。在系统研究的基础,本文总结出两大研究结论:(1)将电子书包作为技术支撑应用于初中化学实验学习是教师在教学中培养学生探究能力的有效途径。(2)基于电子书包的初中化学探究教学模式:技术的丰富性和混合性支撑课前、课中和课后三个过程。课前——构想实验方案、学生主动思考,经历构想的探究过程;课中——实践探究方案,学生抉择资源、观察现象、记录数据、统计结果、归纳结论、评价反思,经历思维训练的学习过程;课后——巩固提升,学生自我练习、加深理解,经历巩固提高的学习过程。
[Abstract]:With the rapid development of social civilization, scientific ability has become one of the important standards for measuring talents in scientific society. Scientific ability includes not only the mastery of scientific knowledge, but also the cultivation of scientific ability. Scientific ability has a long-term influence on individual development, but scientific ability is concentrated on inquiry ability. Inquiry ability is not innate. Learners can improve and develop inquiry ability through experience discovery, conception, choice, induction and evaluation. The purpose of this study is to design a teaching model of junior high school chemistry experiment based on the environment of electronic schoolbag, which takes the cultivation of inquiry ability as the value orientation. First of all, the basic concepts of electronic schoolbag, junior high school chemistry experiment, inquiry learning and teaching model are clarified, and the inquiry learning theory, the constructivism learning theory, the humanism learning theory, etc. Information technology and curriculum integration theory and junior high school chemistry curriculum standards are analyzed. Then, the questionnaire and interview methods are selected to investigate the current situation of some teachers and students in a middle school in Changchun, Jilin Province, and the data are statistically analyzed. It is found that the main concern formula of chemical experiment teaching is explained. It seldom involves the cultivation of students' inquiry ability, the students' strong interest in using electronic schoolbags, and the traditional teaching mode is not suitable for classroom teaching and so on. Then, under the guidance of the concept of intelligent education, the inquiry teaching model under the environment of electronic schoolbag is constructed, and then the model is changed according to the characteristics of chemical experiment inquiry learning in junior high school. Finally, it puts forward the inquiry teaching mode of chemistry experiment in junior high school under the environment of electronic schoolbag. Finally, the effectiveness of the model is analyzed by taking the model of making carbon dioxide gas in laboratory as an example. On the basis of systematic research, This paper summarizes two conclusions: (1) applying electronic schoolbag as technical support to junior high school chemistry experiment learning is an effective way for teachers to cultivate students' inquiry ability in teaching. (2) Electronic schoolbag based junior high school. Chemistry inquiry teaching model: technology richness and mixing support before class, There are three processes in and after class. Pre-class-conceiving experimental scheme, students actively thinking, experiencing the inquiry process of conception; In class-practice inquiry program, students choose resources, observe phenomena, record data, statistical results, inductive conclusions, evaluation and reflection, experience the learning process of thinking training; After-class-consolidate promotion, students self-practice, deepen understanding, experience consolidation and improvement of the learning process.
