Investigation And Research On The Status Of High School Students' Solid Geometry Learning

Geometry is constantly changing with the development of human society.Since the founding of the People's Republic of China,although the curriculum of solid geometry in high school has been changing,the stable and complete Euclidean geometry system has been continuing.Solid geometry is an important content of high school mathematics curriculum,also is one of the high school mathematics learning difficulties,many students' space imagination ability is poor,look not to understand graphics,cannot have the related reasoning,flexible use of mathematical language,from junior high school of transition to the space geometry and plane geometry is a qualitative leap,many students feel difficult than algebraic geometry that is high school,especially the three-dimensional geometric part,students generally feel difficult before they are easy,at the same time,many teachers in the teaching practice,reflection,students in learning this part problem,poor learning effect.In view of this,the following research questions are raised :(1)what is the current situation of high school students learning solid geometry?(2)what are the influencing factors of high school students' learning of solid geometry?(3)what specific teaching Suggestions can be put forward to promote the learning of solid geometry?479 students and 9 teachers from 3 municipal demonstration high schools in a county were selected as the questionnaires and interviews.Taking "solid geometry preliminary" as the content carrier,the literature research method,questionnaire survey method,test paper method,interview The method investigated the above problems,and the current status of high school students' solid geometry learning is:(1)the students' emotional attitude: arts and science students and science information in the study of solid geometry not much difference between interest and a sense of achievement,in the school of arts living on the confidence of learning solid geometry is lower,the school of science living and science information is relatively high;Although there is no big difference between male and female students in their emotional attitude,male students are more interested in learning and more confident than female students.(2)students' learning methods and habits: there are great differences in students' learning methods of solid geometry.In terms of preview habits,only 1/12 students in the class of liberal artsstudents have the habit of preview,and they are not good at independent thinking.Science students and science students do relatively well in preview habits,especially science students have abundant learning resources.(3)students' understanding and mastery of knowledge: what students think is the most difficult is the determination and nature of vertical lines,lines and faces;Especially in the aspect of vertical application,the students' application is not satisfactory.(4)mathematical ability: when students are learning solid geometry,what they lack most is the ability of spatial imagination and logical thinking.(5)homework: students think that the amount and difficulty of homework are moderate,but in terms of their attitude towards doing homework,they have a weak ability to solve problems independently.The habit of science students and science students is relatively good on the record of wrong notes.(6)teaching methods and evaluation: teachers mainly adopt the combination of traditional teaching and multimedia teaching,which is consistent with the teaching methods that students like;Evaluation approach on the formation of core teachers pay more attention to mathematics accomplishment,in the classroom,the students overall reaction,attaches great importance to the evaluation of integrity and periodic,not just in the middle of the teaching process to student achievement evaluation,the school also adopted the tutor system is one-to-one support,about the interview with the student teacher evaluation of the style.The factors influencing the learning of solid geometry in senior high school students are:(1)students' emotional attitude;(2)students' knowledge of plane geometry;(3)students' spatial imagination;(4)students' logical thinking ability;(5)students' learning methods and habits;(6)teaching methods and evaluation methods of teachers.On this basis,according to the requirements of the new curriculum standards,the corresponding teaching Suggestions are provided,including :(1)pay attention to the mathematical culture,improve students' interest in learning solid geometry;(2)reasonably use information technology to cultivate students' spatial imagination;(3)pay attention to the basic knowledge of solid geometry and cultivate students' logical thinking ability;(4)pay attention to students' learning methods and habits,and cultivate students' problem-solving ability;(5)pay attention to the teaching evaluation of solid geometry learning and improve the learning effect of students.
