A Case Study Of Mathematics Teaching In Junior High School Supported By Information Technology

In the past 20 years,information technology has developed rapidly,and it has promoted the reform of education and teaching from all aspects.Basic education with the support of information technology,the teaching environment,teaching contents,teaching means and methods,teaching organization,teaching evaluation,teaching management,and other aspects are proud by changed,interdisciplinary research workers and a line of teacher has been trying to play the role of information technology in the discipline teaching,research on teaching reform,optimize the teaching of the subject.Because of the particularity of mathematics teaching itself and the limitation of conditions,the role of information technology can not play well,many mathematics teachers do not know how to use information technology to support mathematics teaching,also can not see the effect of information technology to support mathematics teaching,so it is necessary to illustrate through the analysis and research of some typical cases.Junior high school as the last stage of nine-year compulsory education,the full use of information technology to support mathematics teaching conditions gradually mature,but also more common,there are a lot of typical cases,this topic choose from this stage,through the case analysis of information technology to support mathematics teaching and the effect.First of all,through literature research,the current situation of information technology support education and teaching,the integration of information technology and junior high school mathemati cs teaching,and the application of mathematical tools in junior high school mathematics are sorted out.Through investigation to understand the application of information technology in mathematics t eaching in minority areas.Then,the classroom teaching supported by information technology is div ided into three types: general classroom teaching,flipped classroom teaching and intelligent classro om teaching.Secondly,By watching a large number of high-quality class teaching videos,typical classroom records were selected for analysis and research,among which the teaching of "direct proportional function"(general class),"understanding triangle"(flipped class)and "image and nature of inverse proportional function"(wisdom class)were selected as the case study objects.By referring to Flanders interactive analysis system and using NVIVO11 video analysis software to conduct coding analysis on the case,it is concluded that information technology supports junior middle school mathematics teaching in six aspects :(1)Support of teaching environment;(2)the support of information presentation and transmission;(3)the support of mathematics teaching activities;(4)the support of teaching evaluation;(5)support as a cognitive tool;(6)Support for students' learning,communication and interaction.Then,through the experimental comparison(the comparison between teaching with information technology and teaching with traditional methods)conducted by me,it is concluded that the mathematics teaching supported by information technology in junior high school has significant effectiveness.Finally,through the analysis of the above cases,it is found that there is a great relationship between the role of information technology and the information literacy of teachers.For this reason,the paper gives four suggestions to junior middle school mathematics teachers: keep up with The Times,enhance awareness;Keep learning and improve yourself;Skillfully organized,reasonable application;Bold innovation,break the limit.
