Research On The Evaluation Of Model Cognition Literacy Level Of New High School Students From The Perspective Of Core Literacy

Standards for General High School Chemistry Curriculum(2017 Edition)model cognition into the core literacy of chemistry.The literacy of model cognition is the concentrated expression of the way of thinking and learning in chemistry,and it occupies an important position in chemistry learning.Cultivating and developing students' model cognition literacy can enable new high school students in the transition stage of junior high school to quickly adapt to the rhythm of high school chemistry learning and improve their learning efficiency.The evaluation of the model cognition literacy level of New Senior One students can provide effective reference for chemistry teachers,and it has a positive effect on the implementation of the core literacy of chemistry in the teaching practice of New Senior One chemistry teachers.On the basis of combing domestic and foreign research,this study uses text analysis to define the connotation of model cognition literacy level from three aspects of quality,consciousness and ability.Based on constructivism,item response theory,and drawing on the experience of PISA2015 scientific literacy assessment,this paper analyzes the literacy level of model cognition,develops an assessment tool for the model cognition literacy level of new high school students,and investigates the current situation of the model cognition literacy level of new senior one students.Analyze the fit between the evaluation tool and the Rasch model,and seek to optimize and improve the evaluation tool;analyze the overall level of model cognition literacy of New Senior One students and the typical characteristics of each level;analyze the model cognition of New Senior One students under different factors Differences in literacy levels,and draw practical investigation conclusions.Then,according to the conclusions of theoretical research and practical investigation,the training strategy is put forward.The main conclusions of the study are as follows: the model cognition literacy level of the new senior one students is relatively low,and the new senior one students show certain differences in the three aspects of model cognition literacy quality,consciousness and ability;When teachers improve the model cognition literacy level of new high school students in practice,they should understand the current situation of the model cognition literacy level of the new senior one students,and according to the current situation of students' literacy level,combine with the real situation in their proximal development zone from the quality,consciousness,ability Three aspects teach students in accordance with their aptitude and implement core literacy.
