Study Of Designing And Applying Camtasia Studios In Secondary Vocational Mathematics Teaching Based On The Autonomous Learning

The rapid development of the Internet has brought the rise of micro film, micro-blog, WeChat and other micro life. The open educational resource "micro-lesson", which is based on the network platform, also has gradually entered the field of educator’s vision. The education idea of open educational resource is popularizing and sharing, which is playing a more and moreimportant role in teaching.My classes are chemical class and computer class, these two classes are in the third year review phase. In the process of mathematics teaching I found that there are the following problems in mathematics learning:(1) some students lack confidence and lack the initiative and enthusiasm in learning, they are not interested in mathematics, and cannot conduct autonomous learning; (2) some students cannot maintain a high concentration of attention in class, their learning efficiency is low; (3) the basic knowledge and basic formula learned in the first and second grades are forgotten very seriously, some students often watch notebook while solving problems, they will not leave notebook in solution; (4) within 45 minutes class time, the moderate or lower-moderate students can only grasp a small part of the content they study, and cannot digest some difficult knowledge and problems during class time, their learning efficiency is lower; (5) within 10 minutes of the recess time, some students have no chance to go to the teacher for asking questions, and moreover although some students have a lot of questions, they are embarrassed to ask.This thesis is to study the following issues. Can use micro-lesson-aided teaching to enhance students’interest in mathematics learning, improve students’attention and improve their autonomous learning ability? What is the concept, characteristics and types of the micro lessons? What is the difference between the micro and traditional lessons? What are the general procedure and the general principle of the micro lesson design? What contents and type of the micro lessons are suitable for students to learn? How should the teacher design micro lessons and which micro lessons should be designed? What is the strategy applied for micro lessons?This study is conducted according to the following procedures. According to the research issues, the literature study is carried out, the autonomous learning theory and the theory of micro lessons at home and abroad are analyzed. This thesis discusses the concept, characteristics and types of the micro lessons, the difference and relationship between the micro lesson and the traditional classroom. It discusses the micro lesson connotation and features of the knowledge understanding category and the example explaining category, and discusses the micro lesson distinction and relation between the secondary vocational school and the ordinary middle school. For selecting the research objects, the computer class is taken as an experimental class and the chemical class is taken as a reference class. The questionnaire survey No.1 is worked out to investigate the understanding situation of the students to micro lessons, so as to make it clear what kinds of the micro lessons are to be produced and explore the general procedures and general principles for mathematics micro lesson design in the secondary vocational school. Then, surrounding the knowledge understanding category and the example explaining category, it is necessary to expand the design of micro-lesson video, and to upload the micro-lesson video to the class QQ group. The students download the micro-lesson video to their mobile phones or computers for learning. The teacher urges students to study micro lessons, uses the classroom assessment, homework evaluation, and test evaluation to understand the students’ micro-lesson learning results, keeps tracking and recording of the learning situation of students, and then works out the questionnaire survey No.2 to investigate the micro-lesson learning effect and the problems existing in the process of learning.This study is from the teaching practice, based on curriculum reform, and adhering to the "student centered" teaching ideas. It innovatively uses micro-lesson to conduct auxiliary teaching courses, effectively improves autonomous-learning ability of students, and develops their learning potential, to make the micro-lesson become an extension of the classroom teaching and to provide a certain reality reference for the future micro-lesson research and design work. However, due to time constraints, it is still needed to further strengthen the theoretical depth, and to carry out more systematic micro-lesson auxiliary teaching in future.
