| In the information age,the Internet has accelerated penetration and integration into all walks of life.In the education industry,the new educational ecology of "Internet plus education" has gradually entered the field of vision of scholars and teachers,and the education of single class teaching is changing.This research adopts the methods of Practice method,Interview method,Questionnaire survey method.Under the background of "Internet plus",the construction and teaching design of mixed teaching mode in middle school chemistry are studied,and empirical research is carried out to explore the basic mode of mixed classroom teaching and the basic paradigm of instructional design,and provide some new ideas for the reform of chemistry classroom teaching in middle schools.The main contents of this study are as follows: First,through literature review,the development and implementation of blended teaching mode are summarized.According to the teaching theory,the blended teaching mode,teaching design and principles and methods are built under the background of Internet plus.On this basis,select the representative teaching content,according to the "general high school chemistry curriculum standards(2017 version,2020 Revision)" to carry out the "literacy based" teaching design,and design two kinds of teaching cases focusing on online and offline.Then,the designed teaching case is carried out in two classes(one is the experimental class and the other is the control class)of grade one in a senior high school in Wanzhou.The experimental class adopts the mixed teaching mode,while the control class adopts the traditional teaching mode.After the teaching practice,the teaching effect of the experimental class and the control class is compared and analyzed by qualitative and quantitative methods,and the teaching practice effect is studied.The results show that:(1)The experimental class is better than the control class in the cultivation of the core quality of the subject,which shows that the hybrid teaching mode can highlight the teaching concept of "student-centered",and is more conducive to the cultivation of the core quality of the chemical subject.(2)From the perspective of academic performance,blended teaching can make students reasonably use fragmented time,preview and review more targeted,and promote the improvement of the overall performance level of the class.(3)From the perspective of learning ability,blended teaching provides students with a variety of learning methods and ways to choose,which is more helpful to stimulate students’ interest in learning and help them form good habits of autonomous learning and cooperative learning,so as to improve their learning ability and learning effect. |
