摘  要：初中化学是在学生初三阶段开设的课程，因而与其他科目相比较，学生对化学的新鲜感、陌生感较为强烈，但同时由于接触化学的时间短，一些初中生“宏微结合”的化学思维方式难以形成，学习效果无法达到初中化学教学中对学生核心素養的培养目标。基于此，本文围绕初中化学教学中“宏微结合”核心素养的有关情况展开探析，首先，阐述初中化学教学中“宏微结合”核心素养的必要性;其次，分析初中化学教学中“宏微结合”核心素养的培养策略，认为要把“宏微结合”与情景教学、深度教学、实验教学相联系到一起，以期能加强对初中学生“宏微结合”核心素养的培养效果，强化学生的化学思维。

Research on the Cultivation of “Macro and Micro Combination” Core Accomplishment in Chemistry Teaching in Junior High School

LUO Xuemei  （No.1 Middle School of Shunchang County，Fujian Province，China）

【Abstract】Junior high school chemistry is in the student courses in the third phase，and compared with other subjects，students of chemistry of novelty and strangeness is relatively strong，but at the same time due to the exposure time is short，some junior high school students “macro to micro combined with chemical way of thinking is difficult to form，learning can not meet the junior middle school chemistry teaching to cultivate students literacy of the core target. Based on this，this paper explores and analyzes the core accomplishment of “macro and micro combination” in junior middle school chemistry teaching. Firstly，it expounds the necessity of the core accomplishment of “macro and micro combination” in junior middle school chemistry teaching. Secondly，the cultivation strategy of “macro and micro combination” core literacy in junior high school chemistry teaching is analyzed，and it is believed that “macro and micro combination” should be combined with situational teaching，in-depth teaching and experimental teaching，so as to strengthen the cultivation effect of “macro and micro combination” core literacy of junior high school students and strengthen their chemical thinking.

初中阶段化学课程教学的一项主要任务是对学生进行化学启蒙，带领学生对化学知识形成初步的了解，认识化学领域内的基本概念，树立起化学学科思维方式。在此过程中，对学生核心素养的培育是达成上述目标的关键，通过学生核心素养的培养，能充分锻炼学生的化学学习以及实践能力，而在初中生化学素养的培养中，“宏微结合”占据着不容忽视的位置，要求从宏观辨识与微观探析两个层面展开教学活动。处于这样的背景之下，初中化学传统教学工作遭遇挑战，需要教师能从“宏微结合”核心素养的视域下出发，探寻初中化学教学的全新路径，为初中生在化学课堂中带来全新的学习体验，也为学生高中阶段化学知识的学习奠定坚实的基础，提高学生解决化学问题的水平。……
