A Study On GeoGebra Aided Linear Programming Teaching

In 2018,the Ministry of Education issued the "education informatization 2.0 action plan",which proposes to strengthen the development and service ability of digital education resources,and improve the construction and application level of information learning environment.In 2020,the outline of the 14th five year plan clearly states that we should speed up the digital development,improve teachers' teaching ability and quality,give full play to the advantages of online education,and build a high-quality education system.In the same year,it was clearly put forward that information technology is an important auxiliary means for students' learning and teachers' teaching in the curriculum standard of general high school mathematics.In this context,the dynamic software GeoGebra is widely used in the field of mathematics teaching with its interactivity and dynamic intuition.This paper studies the theory and practice of linear programming aided by GeoGebra.Through literature research,questionnaire survey and teacher-student interviews,it is found that teachers can not easily explain the geometric meaning of the objective function in linear programming,and students can not grasp the geometric meaning of the objective function and determine the optimal solution.By designing teaching cases and setting up comparative experiments,it is found that the dynamic software GeoGebra can help teachers achieve teaching objectives and teaching difficulties more efficiently,control the classroom as a whole and improve classroom efficiency.At the same time,it can promote students to better understand the geometric meaning of the objective function and determine the optimal solution,so that students can deeply understand the idea of combining number with shape and the idea of optimal solution,and enhance students' ability to analyze and solve problems.It is found that students' learning enthusiasm is higher,the classroom atmosphere is better and teachers' teaching work is easier to carry out.But in the review class,it is not suitable for the auxiliary teaching of GeoGebra software.In a word,GeoGebra software assisted linear programming teaching can not only help teachers improve classroom efficiency,but also help students internalize mathematical knowledge and cultivate mathematical core literacy.
