Research On High School Sequence Teaching Design Based On ACT-R Theory

With the development of new curriculum reform,more and more people pay attention to instructional design.A good instructional design can improve the fluency and effectiveness of teachers' teaching.At the same time,the knowledge of sequence is one of the important contents in the field of number and algebra.However,there are various problems in the actual teaching of sequence.Act-r theory is a simple cognitive theory,taking a "mathematical" path of "simplifying complex problems".Therefore,how to use act-r theory to improve the teaching design of high school sequence,so as to help high school students better grasp and apply the knowledge of sequence is exactly the content of this paper.First of all,this study USES literature analysis method to sort out the domestic and foreign research results related to act-r theory and high school mathematics teaching,and combined with the relevant expression of "Mathematics curriculum standards for general high schools(2017 edition)",to explore the goal and requirements of high school mathematics teaching.Secondly,this study investigated the teachers and students of a high school in Xuzhou by using the interview method and the test paper survey method,so as to understand the current teaching and learning status of high school sequence.Through the investigation,it can be concluded that :(1)the basis for teachers to formulate the teaching objectives of sequence is not reasonable,and the curriculum standards are required to be copied mechanically and mechanically;(2)teachers are not flexible in the selection of sequence teaching methods;(3)The teacher has some deficiencies in the concept of sample design;(4)the "test-taking tactics" have a negative impact on students' sequence learning;(5)the teaching of sequence lacks relevant theoretical guidance.At the same time,students in the sequence of learning there are mainly concepts,formula memory fuzzy;The lack of calculation ability and application ability of the sequence.Then,combined with the results of the above investigation,based on act-r theory,this paper puts forward specific design Suggestions for the teaching design of high school sequence from the four aspects of teaching objectives,teaching methods,teaching content and teaching process.Through the classroom teaching of the two classes in the section of "the concept of geometric sequence and general term formula",it is found from the analysis of teaching effect that the act-r theory-based sequence teaching design can better help students understand and master the related knowledge of sequence.At last,this paper summarizes and reflects on this research,and suggests that the act-r theory should be used in the teaching of number series: reasonably design samples to promote knowledge transfer;highlight the target level and carry out learning layer by layer;strengthen delicate exercises and improve the effectiveness of exercises.
