Teaching Research On “Integration And Practice” Of Junior High School Mathematics Based On Mathematical Core Literacy

“Integration and practice” has been an important part of junior high school mathematics curriculum,which provides unique conditions for the development of students' mathematical core literacy due to its integrity and practicality.However,most middle schools do not pay much attention to implementing of “integration and practice”,and some schools even ignore it directly.In addition,for our country,the research of mathematical core literacy is still in the initial stage.Therefore,the study of “integration and practice” based on the mathematical core literacy is an important measure to motivate schools and teachers to attach great importance to “integration and practice”,and it is also beneficial to teach “integration and practice” in junior high school mathematics,and deepen the study of mathematical core literacy in China.The main content of this article includes the following five parts.For the first part,by literature research method,the domestic and foreign researches related to the mathemat ical core literacy and “integration and practice” are classified and analyzed,and the concepts of“mathematical core literacy of junior high school” and “'integration and practice' of junior high school mathematics” are defined.For the second part,questionnaires and interviews were conducted among first-line junior high school mathematics teachers from Liaocheng Wenxuan Middle School,and finally,some conclusions were drawn as follows.First of all,teachers believe that “integration and practice” is suitable as a part of cultivating students' core literacy.However,due to the lack of ability for teachers,the unsuitable school policies,and the lack of related theoretical instructions,teachers does not integrate well into mathematical core literacy during the implement of “integration and practice”.Secondly,when teachers carry out “integration and practice”,there are problems such as a single teaching method,the selection of teaching content only depending on teaching materials,and the teaching objectives without reflecting mathematical core literacy.Finally,whether it is about the evaluation of students' learning behavior in the classroom or the evaluation of students' learning effects after class,the evaluation methods adopted by teachers are too single,and the evaluation does not aim at mathematical core literacy.For the third part,“integration and practice” of junior high school mathematics for Qingdao version is analyzed in terms of quantity distribution,arrangement system and literacy presentation,and the characteristics of “integration and practice” of junior high school mathematics for Qingdao version are shown.Meanwhile,some teaching suggestions for teachers are illustrated.For the fourth part,based on the survey results and the analysis of the textbook content,the teaching strategies of “integration and practice” for junior high school mathematics based on core literacy are proposed.For the fifth part,based on the teaching strategies before,“practical problem and piece-wise function model” in the junior high school mathematics textbook for Qingdao version is designed.
