Research On The Framework And Practice Of Exercise Design Based On Chemistry Core Literacy

The new curriculum standard of senior high school chemistry advocates that teachers should make full use of the role of classroom exercises and homework when promoting the development of students' core quality of chemistry,and highlight the important position of exercises in teaching.Therefore,how to combine exercise design with the core quality of chemistry is a topic worthy of study.Based on the previous studies,this paper carries out the research of this topic.Taking the content of Chemistry Volume I "matter and its changes" as an example,on the basis of combing its curriculum requirements and related core literacy,this paper puts forward the exercise design framework based on the core literacy of chemistry,and designs exercises according to this framework.Taking senior one students as the object,the exercises are tested,and the validity of the framework is evaluated according to the reliability and validity of the test results.In addition,through the analysis of students' problem-solving situation,the development of students' knowledge and literacy in learning "material and its changes" content is evaluated.The paper mainly includes the following contents:The first chapter introduces the research background,content and significance of the paper,and clarifies the main problems to be solved and the expected research results.The second chapter defines the core concepts and expounds the related research theories.The definition of the concept helps to clarify the scope of the research.The theory expounds the Pisa scientific literacy evaluation framework,curriculum standard academic level examination system framework,solo classification theory.The above theories are the theoretical basis of this paper.The third chapter is the establishment of exercise design framework.On the basis of combing the knowledge and accomplishment of "material and its change",this paper puts forward the framework of exercise design and specifically explains the meaning of design elements.Finally,this framework is used to analyze the exercise of this content in PEP and Luke textbooks.The fourth chapter mainly uses the frame to design exercises and divides the latitude and level of evaluation.Design exercises and explain the design ideas of exercises,put the exercises into practice,and analyze the reliability and validity of the test results.The test results are evaluated from two dimensions of knowledge and literacy to determine the real level of knowledge and literacy evaluation.The fifth chapter takes the level division of the fourth chapter as the standard,introduces the students' problem-solving situation of each level,analyzes the knowledge and literacy of each problem from two dimensions,and uses the statistical pie chart to analyze the knowledge and literacy level of students in the process of solving each problem.The sixth chapter mainly expounds the research conclusions of this paper: first,knowledge,situation and literacy are the components of the exercise design framework based on the core literacy of chemistry;second,most of the senior one students can reach the level of knowledge understanding or knowledge transfer in the knowledge latitude of "matter and its changes";third,most of the senior one students are at the level of knowledge cognition in "matter and its changes" It can reach level 2.The seventh chapter reflects on the shortcomings of this paper.Innovation:1.In this paper,the concept of Pisa scientific literacy assessment and the framework of academic proficiency test are applied to the design of exercises,establishing exercise design framework of chemistry core literacy orientation.2.This paper,based on the use of evaluation method and learning from Yuping's three levels of core literacy and solo classification theory,analyzes the knowledge and accomplishment of senior one students in "material and its changes".
