Research On Unit-based Teaching Design

As a form of teaching organization,unit teaching can gain initiative and freedom for teachers and students through overall arrangement.From the existing research data,we can get the development history and related theories.At present,teaching design based on various forms and characteristics has been studied to a certain extent,and unit-based teaching design is no exception,but the lack of implementation examples can not provide front-line teachers with operating directions and more references.Based on the unit perspective,this paper realizes unit-based teaching design and teaching implementation through research.Through the combination of theory and practice,it adopts literature method,content analysis method and experimental method to show that it is scientific and effective to help students construct a knowledge structure system through unit instructional design.Based on the large unit of equations,the article selects the content of the small unit "linear equation with one unknown" in the fifth chapter of the seventh grade book published by Beijing Normal University Press to conduct unit-based teaching design,and then test the implementation effect.The purpose is to mainly solve the following two problems:(1)Provide implementation cases of unit-based instructional design;(2)Verify the implementation effect of unit-based instructional design.This research understands the research background and research significance through the literature method and content research method,and draws the theoretical basis of this research;Determine and refine research plans and methods.Construct the unit framework based on the large unit of equations,analyze the unit teaching elements from the course standard,mathematics,teaching materials,important and difficult points,and teaching methods,formulate the overall teaching objectives and complete the class period allocation;A questionnaire survey was carried out at C Middle School in C city.The main purpose is to understand the learning situation of the upper grade(grade 8 and 9)students in the equation unit,provide guidance and reference for the small unit teaching design,and to a certain extent foresee the possible occurrence of students Problems,as well as the preliminary verification that traditional classroom teaching will cause the separation of knowledge.Next,take the unit of linear equation with one unknown as an example for teaching design.In the article,three representative class hours are selected to show the teaching process in the form of classroom records.After completing the implementation of the small unit teaching design,the test will be conducted,and the test scores will be tested and analyzed by independent-samples t test using the SPSS22.0.It is concluded that there is a significant difference between the experimental class and the control class,especially in the volume B.It can be seen that the teaching design of the unit can help students to establish a knowledge structure framework,and can help solve more difficult problems.Through this research,it is hoped that unit-based instructional design can enter the field of vision of more front-line teachers,and provide reference for trying and implementing unit-based instructional design,and help them realize the feasibility of unit-based instructional design,especially mathematics teaching in junior high school.
