在大部分初中学校已经先后有规划地开展“互联网+”教育的今天，数学教师是否能合理运用“互联网+”教学工具以满足学生在数学科目上核心素养的发展，从而达到高效的数学课堂，这是一个值得思考和讨论的议题。因此，本研究对不同地区的学生、数学教师发放问卷来调查“互联网+”背景下的初中数学课堂教学有效性及初中数学教师信息化教学能力，分析相关情况后提出可能的优化措施。研究表明：（1）所在教学地区越发达、学校在信息化教学方面提供的支持越好，初中数学教师信息化教学能力就越强；（2）经常处于信息化教学环境下的学生对知识、技能和方法的掌握程度优于经常处于传统教学环境下的学生，前者对于数学学科的情感态度价值观比后者更积极主动；（3）初中数学教师借助“互联网+”工具教学可能的优化完善措施不仅需要考虑教师教学方面和学生应用角度，也需要多方的共同努力。本研究以期提高“互联网+”背景下的初中数学课堂教学有效性，推动促进初中数学学科教育的创新和发展。

Today, when most junior high schools have successively carried out "Internet +" education in a planned manner, whether mathematics teachers can reasonably use "Internet +" teaching tools to meet the development of students' core literacy in mathematics subjects, so as to achieve efficient mathematics classrooms, is a topic worth thinking about and discussing. Therefore, this study sent questionnaires to students and mathematics teachers in different regions to investigate the effectiveness of junior high school mathematics classroom teaching and the informatization teaching ability of junior high school mathematics teachers under the background of "Internet+", and put forward possible optimization measures after analyzing the relevant situation. The results show that: (1) the more developed the teaching area and the better the support provided by the school in terms of information teaching, the stronger the information teaching ability of junior high school mathematics teachers; (2) the mastery of knowledge, skills and methods of students who are often in the information teaching environment is better than that of students who are often in the traditional teaching environment, and the former is more active in the emotional attitude and values of mathematics than the latter; (3) the junior high school mathematics teachers use "Internet +" The possible optimization and improvement measures of tool teaching not only need to consider the teaching aspects of teachers and students, but also need the joint efforts of many parties. The purpose of this study is to improve the effectiveness of junior high school mathematics classroom teaching under the background of "Internet+" and promote the innovation and development of junior high school mathematics education.
