【摘要】 新课程的改革是一项涉及教育理念、教学方法、教材评价的全方位的改革,课程改革的关键在于课堂教学实践,而化学情景教学设计就是新课程背景下化学教学改革的一个很好的突破口。在化学教学中,教师应该深入地分析教材,结合学生的认知心理特点,努力创设教学情景,优化课堂结构,从而激活学生的思维活动,培养学生的求知欲和创新能力。情景教学对培养学生的情感、启迪思维、发展想像、开发智力具有重要的作用,学生在教师设计的鲜活、具体的情景下进行学习,有利于促进学生学习方式的转变,充分体现学生的主体地位,培养和提高学生的自主学习能力。因而科学并有效地创设化学课堂教学情景,是化学新课程教学的重要任务之一。本文阐述了情景教学的历史背景、发展现状及新课程背景下情景创设研究的必要性,介绍了情境创设的心理学理论和教育学理论基础:行为主义心理学,操作性条件反射学习理论以及发现法学习理论,认知——同化学习理论,建构主义学习理论等,探讨了情景教学的特点、原则与情景创设教学研究的意义。通过本人对所在学校高一高二年级的调查报告的分析,总结了当前情景教学的实施现状及存在的问题:学生的主体性体现不深,没有构筑全体学生统一的平台,学生的情感体验注重不够等。针对这些问题,在研究了情景教学的程序后,本人又通过生动的案例结合教学实际,着重介绍了化学课堂教学情景创设的具体途径与方法,为化学教师优化课堂效果、培养学生积极性、提高学生学习效率、改进教师的教学方法提供了借鉴与启示。最后本人对情景创设教学资源的收集、开发与再加工进行了探讨,丰富了情景创设的内容,符合了我省化学新课程改革开展的需要。更多还原

【Abstract】 The new curriculum reform is the omnidirectional one that involves the education idea、the teaching method、the teaching material appraises.The key of the curriculum reforms rests with the classroom instruction practice, while the chemistry scene teaching design is a very good breach of chemistry educational reform under the background of new curriculum. In chemistry teaching, the teacher should analyze the teaching material thoroughly and struggled to establishes the teaching scene, optimize classroom structure combining student’s cognition psychology to activate student’s thinking activity ,raise student’s intellectual curiosity and innovation ability.The scene teaching plays an important role in raising student’s emotion,edifying thought,developing imagination and intelligence. The student study under vivid and concrete scene designed by teacher ,which is advantageous in promoting the student to alter their studying mode, manifest student’s main body status fully and then enhance student’s independent learning capability.Thus establishing the chemistry classroom instruction scene scientifically and effectively is one of important tasks for new chemistry curriculum teaching.This article elaborates the historical background,the present development situation and necessity of the scene establishment research. It also introduces the foundations of psychology theory and education theory about scene establishment,such as the behaviorism psychology, the operational conditioned reflecting study theory, the discoverying study theory, meaning theory and the construction principle study theory and so on. At the same time, it discusses the scene teaching characteristics, principles and theory significance of the scene establishment teaching research.Through the investigation report of the students in senior one and two in my school,we find there exist some problems about the current implementation situation of scene establishment. For example, the student’s independent is not manifested deeply, the uniform plat of all student has not been constructed, student’s emotion experience has not be payed enough attention and so on.In view of these questions, after the scene teaching procedure has been researched,the concret ways and methods of chemistry classroom teaching scene establishment are introduced in this article through the vivid teaching case combining the teaching. Also it provides the teacher models and enlightenments to optimize the classroom effect for chemistry teacher, cultivate the student’s positivity, raise the student’s study efficiency and improve the teacher’s teaching method.Finally,the collection, exploitation and reprocessing of the scene establishment teaching resource have been discussed ,which enriches the scene establishment level and is accorded with the requirement of the chemistry new curriculum reformation in our province.更多还原
