Research On Project-based Learning Practice Based On Core Literacy

With the in-depth development of curriculum reform,how to realize the teaching transformation from "knowledge-based" to "literacy-based",to implement the goal of moral education and comprehensive education of subjects,and promote the development of students' core literacy,has become a hot topic of education reform in the new era.Theoretical and practical research on education reform in various countries shows that project-based learning is one of the effective ways to implement students' core literacy and comprehensive development.Project learning stressed based on curriculum standards and the requirements of teaching content,around challenging and complex problem situations,the integrated use of learned knowledge and skills,in the form of cooperative group learning,in the process of practical experience,internalization and absorption and innovative application,explores the connotation and extension of subject knowledge,build a more specific and systematic cognitive system.Project-based learning is considered to be an effective teaching mode to cultivate innovative,compound and application-oriented talents in the 21 st century.This study uses a combination of theoretical and empirical method to explore the implementation framework of high school chemistry project learning.Through consulting a large number of literature,the development status of project-based learning at home and abroad is sorted out,and the research opinions,methods and results of domestic and foreign scholars are summarized to determine the research ideas of this paper:First of all,the current situation of chemistry learning in senior high school and the implementation of project-based learning was understood through a questionnaire survey on the classroom learning of senior high school chemistry students and interviews with front-line teachers.Secondly,in terms of case selection,sugar knowledge is involved in the teaching content of junior and senior high schools.Sugar property experiment is one of the experiments required by the curriculum standard,which is closely related to production and life.Based on this,the project of "Preparation and application of maltose" is developed and designed,take "the production and application of maltose" as an example to learn the relevant knowledge of starch sugar.Guide the students to explore the properties and applications of starch and its hydrolysate from two perspectives of industrial sugar production principle and product deep processing to cultivate students' scientific attitude and social responsibility.Finally,Roll face results,student interviews and evaluation scales of the experimental classes were analyzed to test the effectiveness of the project-based learning.The results show that project-based learning plays a positive role in changing students' learning attitude and improving their learning interest,and can promote the development of students' core accomplishment of chemistry subject,which is conducive to realizing the educational value of subject teaching.The last chapter of this paper analyzes and summarizes the teaching practice of the research project,reflects on the problems after the implementation of the project,and puts forward guidance and suggestions for the implementation of project-based learning,providing reference for subsequent researchers.
