Research On The Application Of Micro-courses In High School Mathematics Review Course

In order to pursue the effect and efficiency of review,mathematics special topic review courses may compress the course content,lengthening the explanation time of key content and high-frequency topics,while other parts are not explained in depth,which is easy to lead to students’ lack of mastery of some non-key content.High school mathematics special topic review courses can use micro-lessons as the main learning video,and provide a certain degree of independent learning and teacher guidance on the basis of micro-lessons to strengthen the mastery and sorting out of knowledge.This helps students learn and master mathematics,and makes teaching more relevant and interactive.This research mainly explores the teaching application of micro-lessons in high school mathematics review courses.Firstly,through literature combing,we understand the development process and research status of micro-courses at home and abroad,clarify the core concepts such as micro-courses,and summarize the application of constructivist theory,micro-learning theory and cognitive load theory in the fields of micro-course mathematics teaching.Secondly,a questionnaire survey was conducted to survey teachers and students of the internship school.The survey results show that students and teachers are very inclined to apply microlessons to the classroom of high school mathematics topic review class.Thirdly,the teaching content of micro-lessons applied to high school mathematics special topic review courses is designed to achieve the purpose of assisting teachers in the classroom and facilitating students’ self-study outside the classroom.This paper takes the special topic review course "The Maximal Value Problem of Quadratic Functions on Closed Intervals" as an example,and takes the two classes of micro-class and control class as examples to carry out control experiments.Finally,two classes of the internship high school were selected as experimental subjects.Through control experiments,questionnaires and other methods,the use effect of micro-lessons in mathematics special topic review courses was tested.Through the above research,it is found that the short and concise videos of micro-courses can make students master and digest the knowledge points,and help students review and learn on their own.The micro-course contains more comprehensive knowledge points,which can accurately grasp the difficult points and solve complex problems,increase the practical application links,and make practice a skill and habit for students to learn mathematics.Students are also free to master the learning elements and learning pace.However,there are still problems such as lack of interaction and feedback,teachers becoming narrators,and insufficient students’ self-control ability,and micro-lessons need to be designed according to the actual teaching situation.
