A Research On Chemistry Teaching "the Integration Of Teaching,Learning And Evaluation" In Terms Of Core Literacy

With the introduction of core literacy,classroom teaching and evaluation have undergone corresponding changes.The 2017 edition of High School Chemistry Curriculum Standards proposes that the implementation of "quality-based" teaching and evaluation based on the core literacy of chemistry subject should be emphasized,and the integration of "teaching,learning and evaluation" should be actively advocated.How to teach and evaluate the core literacy,how to design teaching,learning and evaluation in an integrated way,and how to realize the integration of teaching,learning and evaluation in practice,these are all subjects worthy of our deep thinking and research.Based on the literature analysis of the status quo,understand the implementation of the status quo through investigation,based on the first-line classroom teaching to carry out research,the thesis intends to deal with the following issues:(1)It combs the quality-based teaching design of the basic process,constructs an integrated design and implementation framework of "teaching,learning and evaluation",and illustrates the concrete operation of each link in the model with the case of "Chemical Equilibrium".(2)Taking the thinking level,the practical level and the value level corresponding to the core literacy of chemistry as the three evaluation dimensions of the evaluation design,it clarifies the Evaluation Angle and the concrete connotation of the evaluation level under each dimension;(3)Carry out the practice research on the basis of the model design teaching case.The results show that the integrated teaching of "teaching,learning and evaluation" promotes the development of students' chemistry core literacy to a certain extent,it is shown as follows:(1)Model-based design and teaching can effectively improve the students' ability to deal with high-level examination questions;(2)It can effectively promote the change of students' learning style;(3)It can improve the students' thinking quality;(4)It helps to improve students' study initiative.
