Research On Teaching Design Of Chemistry Based On STEM Education And Core Literacy

With the issuance of the "general high school chemistry curriculum standards"(2017 edition),core literacy has become a research focus in the field of basic education.It is of great value for students' future comprehensive development to pay attention to the implementation of discipline literacy in teaching.STEM education originated from the United States has the characteristics of focusing on real issues,interdisciplinary,and forming creative materialized works,which can promote the improvement of teaching level under the guidance of core accomplishment.Therefore,the concept of STEM(STEM stands for the first letter of the English word for Science,technology,engineering and mathematics)education is permeated into teaching design,which has become a hot topic in basic education research in recent years.Of this study is to train innovative talents for the spot based on STEM education with the core literacy teaching case after the concrete implementation,form the "erection-penetration-generation" of the "class,class,after class" STEM teaching process,to promote students' deep learning and the development of higher order thinking ability,improve teaching quality plays an important role.Based on the theoretical aspects are studied,by using the method of literature analysis and so on integration with comb STEM education route of the development of the research status at home and abroad,found that there are very few in our country under the core quality perspective,based on STEM education for teaching system design for a certain subject,most of the system is discussed from the aspect of theory to it.This study focuses on the convergence of STEM education and core literacy,On this basis,explain the concept of STEM education,that the relationship between dialysis,select four related self-efficacy theory,the theory of multiple intelligences theory as the theoretical support of research,combining with the characteristics of high school chemistry teaching,the questionnaire,to a high school chemistry discipline STEM education current situation of the fishing expeditions,to master its structure level,On the basis of it,some in-depth issues were further obtained by interview.The results showed that although many teachers and students affirmed the value of STEM education and teaching,there were still some misunderstandings and confusion.Therefore,it is necessary to improve students' ability to learn chemistry by infiltrating STEM education and teaching.Based on the analysis of the main columns and descriptions in the latest compulsory 1 textbook of the people's education edition,the author designed and implemented teaching cases based on STEM education and core literacy,such as the solution with the concentration of certain substances to determine the content of iron in black fungus and the exploration of ethylene.By means of after-class interviews,exercise tests,and before and after performance comparisons,it is concluded that the chemistry teaching design based on STEM education and core literacy is feasible and effective in teaching practice.The teaching design of chemistry courses will be permeated with STEM educational concepts can strengthen the horizontal connection between different disciplines,better improve students' comprehensive thinking and ability,and bring reference significance to the reform of teaching and learning forms.
