Research On The Teaching Design And Implementation Of Mathematics PBL In Junior High School From The Perspective Of Core Literac

The 21st century presents new challenges and requirements for talents.Countries all over the world begin to pay attention to the cultivation of citizen core literacy,which makes core literacy gradually become a hot topic in education.Core literacy is closely related to individual development,and the cultivation of students’ core literacy is inseparable from the "support" of daily teaching.One of the key points of cultivating students’ core literacy is to adopt scientific and reasonable teaching methods.PBL teaching can better integrate "core literacy","teaching" and "problems" into one,and has a good fit with the core literacy,which can provide a new "foothold" for the cultivation and penetration of core literacy in junior high school education.Therefore,this paper focuses on the instruction of scientific and reasonable PBL teaching of junior middle school mathematics from the perspective of core literacy,and studies its practical effect through teaching implementation.This study mainly adopted the method of literature review to sort out and analyze the previous domestic and foreign research literature on PBL teaching in the field of mathematics,defined the concepts of core literacy,PBL（problem-based teaching）,teaching instruction and teaching cases,and determined four theoretical bases.H,W and collect Z province area of more than fourth middle school outstanding teachers of mathematics of fragments of PBL teaching case analysis,and then based on PBL teaching instruction principles,to "binary solution equations（1）" for the specific content of the core literacy PBL teaching instruction under the perspective of junior middle school mathematics,on the basis of using the method of questionnaire survey to study the status quo of teaching of selected experimental class,Then carry on the teaching implementation,finally analyze the practical effect through the classroom observation method and individual interview method,and summarize the following conclusions: First,PBL teaching in junior middle school mathematics teaching can improve students’ ability of independent learning to a certain extent,stimulate students’ interest and enthusiasm in learning,help students establish a correct view of learning,and can well stimulate students’ "passion" for cooperation.And make them dare to express their own ideas and objective things "bold" and based on speculation and evaluation,which is conducive to students’ future learning and exploration of mathematical knowledge;Second,the PBL teaching can promote students actively "thinking to solve the problem" diligently "cooperative exploration of old and new knowledge" and "rational assessment objective physical",in the teaching process subtly to cultivation of the core,and students can live and work in the future for the student,which has laid a good foundation to promote the all-round development of students.
