摘要:文章结合当下新课程所强调的“注重生活”与“联系现实”教学理念,以初中化学为切入点,通过将初中化学教学生活化,探讨利于促进学生学习化学知识的积极性。研究从实施方法、具体案例到经验剖析等层面,运用与生活贴切的话题引入新课,将日常生活中的有关现象融入化学教学。研究认为,这既可激发学生的学习兴趣,也为一线讲授初中化学的教师提供教学参考的思路。
Abstract: This paper, integrated with the teaching philosophy of "focusing on life" and "connecting with reality" emphasized by the current new curriculum, taking junior middle school chemistry as the breakthrough point, through adapting chemistry teaching of junior middle in life setting, explores the ways activating students' enthusiasm toward learning chemistry knowledge. This paper studies on various stages from the implementation methods, specific cases to experience analysis, and applies topics with an inch of life to the inducement of new lessons, penetrates the phenomenon that happens in daily life into chemistry teaching. This study argues that it can both stimulate students' interest in learning and also provide an instruction reference for teachers involved in chemistry teaching in junior middle school.

1 问题的提出与理论基础
作为新课程强调“注重生活与现实联系”的理念,已经成为当前化学课程教学标准的新要求。因为,化学是一门很实用的科学。然而,长期以来,受传统的教育理念以及“应试”目标的影响,我国初中化学教学出现了偏差[1]。体现在:重视理论,轻视化学与社会、生活、生态的关联及影响;重视知识认知,轻视情感和意志的培养;重视结果,轻视科学的思想、过程与方法。在初中阶段,学生刚刚接触化学这一学科,更要将化学教学贴近生活,融于生活,让学生主动去揭开“化学”这门科学的神秘面纱。要实现这一目标,就要将化学教学与实际生活有机联系,引导学生用化学知识去观察生活,思考生活,使学生主动用化学知识去分析、处理简单的生活问题,让学生真正地走进奇妙的化学世界,提升学生的化学素养。并且,注重理论与现实生活的联系也是新课程的基本理念之一,新课程强调理论知识应与生活、社会、生活实际等相联系[2]。……
