High School Students Study Of Geometric Progression Level

Geometric progression not only improves the knowledge structure system of high school function,but also covers a large number of mathematical thinking methods.Secondly,the rich practical background provides a reliable source material for the cultivation of students' "four-energy" ability.Mathematical understanding has become a new topic of concern in today's mathematics education circles,so under the concept of the core accomplishment of mathematics at present,what is the level of understanding of Isogram among high school students at this stage?What is the understanding level of geometric sequence of current high school students?What influence students ' learning isogram,and thus better teaching and learning,is what we want to study.With the help of SOLO classification theory and the method of literature analysis and investigation and analysis,this paper analyzes the distribution of the understanding level of high school students isogram from the concept of Isogram,the formula of Isogram,the combination of the former n subparagraphs of the Isogram series,and the comprehensive practical application of the 4 dimensions.Combining with the investigation results,this paper analyzes the factors that affect students ' isogram learning;According to the problems found,the following conclusions are drawn from the point of view of teaching and learning:1.The students 'understanding of the concept of Isogran,the formula of Isogram and the comprehensive practical problems of isogram are not different,and they are mostly at the level of correlation structure or extended structure Students 'understanding of the first n items of Isogram is mostly at the level of the associated structure.2.There will also be some differences in the understanding of isogram among students of different grades,but there is little difference.The overall level of understanding in senior High is higher than sophomore overall understanding level,of which the most influential is Isogram's general formula dimension.There was no significant difference in the knowledge understanding of isogram between boys and girls.3.Students 'understanding of mathematical thinking methods is not thorough enough to understand their connotations deeply,such as "dislocation phase subtraction","accumulation method" is only understanding,but can not be fully used.4,Some students do not pay enough attention to the basic knowledge of isogram,and are eager to generalize the question type and join the sea.Some students have difficulty in the formal memory of mathematical symbolic language,the understanding of Isogram is not thorough enough,but blindly apply formulas and ignore the essence of knowledge.5.The influencing factors are roughly divided into:light basic weight solving,poor mastery of mathematical thinking methods,insufficient attention to mathematical core,the accumulation of bad learning habits and the influence of teacher factors.The suggestions put forward are as to establish a complete isogram knowledge generalization,strengthen the mastery of mathematical thought methods,attach importance to the process of knowledge acquisition,strengthen the understanding of formal meaning,attach importance to the improvement of computing ability,and emphasize the cultivation of innovative diversification.The suggestions put forward are as to establish a complete isogram knowledge framework,attach importance to the penetration of mathematical thinking methods,strengthen the understanding of mathematical symbols,and promote the diversification of formula derivation.
