Research On The Design Of Analytical Chemistry Teaching In Secondary Vocational Schools Under The Flipping Classroom Teaching Mode

Secondary vocational schools believe that the state and society to train skilled talents and high-quality workers for the purpose of running a school.Therefore,the state is constantly promoting the development of secondary vocational education,but there are still some problems in the development of secondary vocational education.For example,in traditional teaching,the main position of students as classroom teaching activities is often not fully reflected,imparts knowledge in one direction,and the teaching form is relatively simple,which leads to students’ low interest in learning.Therefore,in order to improve the shortcomings of secondary vocational teaching,we try to apply the flip classroom teaching model to the secondary vocational teaching.This study takes the intermediate-level analytical chemistry course as an example to implement the flip classroom teaching mode.Firstly,the paper analyzes the teaching materials,the learning content,the training objectives of the major,the teaching status quo and the learning situation of the secondary vocational students.In addition,the design of the three teaching links before,during and after the course of the inverted classroom teaching of the analytical chemistry of secondary vocational schools.For the content of this book,42 micro-course videos,teaching PPT and task lists were designed and produced in the pre-course preparation process,enriching the learning resources for the implementation of flip-table classroom teaching in secondary vocational schools.Classroom teaching designed teaching activities such as preview feedback,teacher-student questions,classroom lectures,teacher questions,experimental operations,class summary and reflection after the class,the knowledge consolidation,expansion and learning evaluation were designed.Finally,taking the two parts of "Capacity Analysis Instrument and Basic Operation" and "Preparation and Calibration of Sodium Hydroxide Standard Solution" in the analytical chemistry of secondary vocational school as an example.Specifically,the three sections of the pre-class,in-class and post-class of the reversal classroom teaching were designed,and carried out the practice of flipping classroom teaching.The results of questionnaires,grade tests,interviews and other research methods are used to obtain the effect of analytic chemistry inversion classroom teaching practice in secondary vocational schools,etc.,namely: the flipping classroom teaching mode breaks through the traditional teaching mode.It uses modern people’s way of thinking and informational means to teach,which is more in line with the characteristics of secondary vocational students.The way of imparting knowledge is also more conducive to the acceptance of secondary vocational students.Flipping the classroom teaching mode is more conducive to enhancing students’ interest in learning,improving students’ experimental operation ability and cooperation ability,and it is more conducive to strengthening students’ communication skills and increasing communication opportunities between teachers and students.In addition,this paper looks forward to how secondary vocational schools can better carry out the practice of flipping classroom teaching.
