Research On The Application Of Situational Teaching Method In The Teaching Of Graphics And Geometry In The Lower Grades Of Mental Retardation

Optimizing the teaching methods of special education is the meaning of improving the quality of classroom teaching in special education schools.In view of the particularity of mental and physical development of preschool children,The Curriculum Standards for Compulsory Education in Preschool Schools（2016）provides detailed guidance for the teaching,evaluation and implementation of preschool courses,which is of great significance for improving the quality of preschool classes.At the same time,improving the quality of classroom teaching in special schools is also the requirement of the education itself.In this study,the paradigm of action research,the use of observation method,interview method,test method to the situation teaching method in the lower grades of graphics and geometry teaching to conduct a more in-depth study,the real evaluation of students’ classroom performance,in order to explore a more suitable situation for the teaching of graphics and geometry.Based on constructivism theory,situational cognitive learning theory and zone of proximal development theory,this study explores the application of situational teaching method in the teaching of graphics and geometry in lower grades.Through observation and interview,the following problems exist in the teaching of graphics and geometry in the lower grades of H School: single teaching method,low learning enthusiasm of students and insufficient attention to the learning process of students by teachers.Teaching practice is carried out on the basis of analyzing the situation of science and teaching materials and determining the research collaborators and participants.In the implementation process,the third grade of H training school is taken as the research cooperative class,and the situation teaching method is applied to the life mathematics graphics teaching of the lower grades of training school by using observation method and test method and the basic paradigm of action research.The research includes one observation stage and three implementation teaching stages.Teaching practice and reflection are carried out through four steps of "finding problems,making plans,implementing teaching and teaching reflection".Firstly,situational teaching method is applied in the teaching of Cognition rectangle,and it is found that students lack subjectivity in learning and prefer the teaching situation of game,and some improvement measures are put forward.Secondly,the situation teaching method is applied to the teaching of Cognition square,and it is found that the students’ understanding is not good and the classroom evaluation is not enough.Finally,the paper applies the situational teaching method to the teaching of Understanding triangle,and finds that the situational teaching method is beneficial to stimulate children’s learning interest,develop good learning habits and improve their academic achievements.After three rounds of teaching,this paper analyzes the influence of situational teaching method on students and teachers in the teaching of graphics and geometry: improving students’ enthusiasm in class,cultivating students’ good learning habits,improving teachers’ teaching ability,and building a harmonious teacher-student relationship.It is found that the optimal path of situational teaching method in the teaching of graphics and geometry in lower grades lies in: solid professional knowledge foundation of teachers;Situational creation revolves around students’ daily life;Flexible use of situational teaching method;Value the learning process of students.
