Application Of Micro Class In Solid Geometry Teaching

In the age of big date,the voices of individualized autonomous learning have been running high.Micro lessons impose a micro-video as the supporter,arise at the historic moment.In micro lessons the teaching time is streamlined.Micro lessons have the characteristics of strong teaching pertinence,repeatable playback and easy to spread,which have become the hot spot of education nowadays.Solid geometry plays an important role in high school mathematics teaching.It can cultivate students’mathematical intuition,logical reasoning,mathematical calculation and other disciplinary qualities.The integration of micro-lessons and solid geometry teaching has great practical significance,which innovates the teaching mode and highlights the principal position of students.Based on this background,the author studies the application of micro-lessons in the teaching practice of solid geometry.Through literature review,the author finds that there are few practical researches on the micro courses of solid geometry,which are usually only aimed at a certain class or several specific classes and are not practical.The author designs a series of micro courses for solid geometry teaching in the third year of high school,which is closely related to the examination points and the weak knowledge points of students and forms a system.This research is mainly divided into three parts,namely,the design of micro-lesson teaching,the implementation of micro-lesson process and the evaluation of micro-lesson teaching effect.At first,the author reads and organizes the relevant literature,introduces the concept and the features of micro-lessons,determines the principles of designing micro-lessons and standardizes the production process of micro-lessons.The author combines with learning situation diagnosis,sorts out the knowledge points and core points of solid geometry.On this basis,the author mads a series of micro courses of solid geometry and carries on the case shows.Secondly,the author takes two parallel classes of science in senior three of the teaching school as the experimental group and the control group respectively.The students of the two classes are taught by the same teacher,which are at an equivalent level.On the basis of the teaching schedule,students in the experimental group learn micro-lessons after class,while students in the control group only carry out traditional teaching.Students in the experimental group can download and learn micro-lessons on a variety of mobile terminals,like cellphones and computers.The teacher can track and manage students’ learning status.At last,by means of questionnaire survey and result comparison,the author studies the influence of micro-class on students’ interest in learning solid geometry,understanding and application of knowledge,learning behaviors and academic performance,etc.According to data analysis of questionnaire and post-test learning scores,the author checks the effectiveness of micro-class teaching.The research shows that the experimental group students’ performance is significantly improved,and the micro-lesson teaching achieves good learning effect.Micro-lesson teaching has been recognized by students,which improves students’ interest in learning solid geometry and students’ knowledge understanding.Micro-class teaching improves students’ learning enthusiasm,is conducive to students’ knowledge construction,and has a positive effect on the cultivation of students’ independent learning ability.This study puts solid geometry micro-lesson teaching into practice,which has certain referential values for teachers in the exploitation of micro-lessons.Finally,the author analyzes the shortcomings of this study and puts forward a prospect for the follow-up researches.
