Design And Practice Of Junior Middle School Chemistry Micro-projects Oriented By Core Literacy

With the progress of curriculum reform,the development of students' core literacy has become the core concept of middle school teaching.The core literacy puts forward new requirements for the development of students' comprehensive ability in junior middle school chemistry teaching.Micro-project learning is a new teaching model that contextualizes the core knowledge of unit class hours,reduces the difficulty of the task,stimulates students to think with driving questions,and completes the project results in the regular classroom in a short time.It can fit the new curriculum to cultivate the core of chemistry for junior high school students.The concept of literacy.Therefore,this paper conducts a core literacy-oriented junior high school chemistry micro-project design and practical research,in order to design and develop junior high school chemistry teaching cases based on micro-project learning,and explore the role of micro-project learning in promoting the development of students' core literacy,so as to serve as a junior high school student.The theory and practice of chemistry teaching provide guidance.This paper uses the literature research method to sort out and analyze the domestic and foreign literature on core literacy,project-based learning,and micro-project learning.In this way,the concept of the core literacy of junior high school chemistry and micro-project learning is defined,and based on the project learning concept of the Barker Institute of Education,a micro-project learning model oriented by the core literacy of junior high school chemistry discipline is constructed,and the corresponding teaching implementation links are designed and corresponding Implementation principles and strategies.Based on this,according to the selected micro-project theme,this article has designed "designing a laboratory for oxygen production manual" and "exploring how to use black medlar for testing with driving questions,core knowledge,task activities and literacy connotations as clues." Three teaching cases of acidity and alkalinity of solution,and designing an experimental plan for extracting sodium chloride from crude salt,and a teaching practice in a middle school in Ningxia.Finally,the effect of the teaching model was evaluated through interviews and questionnaires..The research results show that it is necessary and valuable to carry out micro-project learning based on core literacy.Micro-project learning avoids lengthy practical research,and students can produce project results in a short time and gain a sense of self-efficacy.It can fully mobilize students'interest in learning and increase their enthusiasm for learning.While focusing on cultivating students'"rational thinking","problem solving",and "dare to explore" literacy capabilities,it can also enhance students' comprehensive abilities.Therefore,micro-project learning is expected to be widely used in normal teaching in the future.
