Investigation And Research On Elliptic Learning Obstacles Of Senior Two Students

As an important part of the elliptic conic curve,it is not only the key and difficult point in senior high school mathematics learning,but also the hot spot of college entrance examination questions over the years.However,from the perspective of students' actual learning situation,there are still many obstacles for students to learn ellipse.So what obstacles do students have in elliptical learning,and what are the reasons that lead to the obstacles? These are all problems that need our in-depth study.From the perspective of cognitive psychology,this study makes an in-depth analysis of the learning obstacles of senior two students in the process of elliptical learning by combining test papers and questionnaires.Through investigation,it is found that the learning obstacles of senior two students in elliptical learning are mainly divided into three aspects: first,cognitive obstacles,which refer to the obstacles caused by students' graphic perception,conceptual memory,understanding or drawing,etc.,which are embodied in difficulties in understanding mathematical knowledge,memorizing and graphic perception.Second,operational obstacles,which refer to the obstacles existing in activities such as knowledge application,problem-solving ideas and proof methods,choice of nature or thinking methods,graphic imagination,etc.,when students apply mathematical knowledge to solve problems in the learning process.The specific manifestations are poor mathematical analysis and application ability,weak mathematical operation,reasoning and argumentation ability,etc.Third,emotional obstacles,which refer to the obstacles caused by students' own inner psychological state in their learning activities,which are manifested in unstable psychological development,bad study habits,fear of difficulties or resistance,etc.After classifying the elliptical learning obstacles,the author deeply analyzes the causes of each obstacle,and on this basis,puts forward the following teaching suggestions.First,based on cognitive barriers,it is proposed to promote teaching contextualization;Deepen the knowledge network;Improve the ability of mathematical expression.Secondly,based on operational obstacles,it is put forward: attaching importance to the infiltration of mathematical thinking methods;Strengthen the calculation ability;Improve logical reasoning ability.Thirdly,based on emotional barriers,it is proposed to enhance self-efficacy;Build a good teacher-student relationship;Establish a clear learning purpose and plan.
