The Design Of Chemistry Learning Situations For Evaluating Core Literacies

As the main body of education reform,core literacy education is getting more and more attention from academic circles.The core literacy of students is to cultivate higher-level talents to meet the requirements of the development of the times,with the characteristics of the times and forward-looking.As the carrier of core literacy,the core literacy of the discipline is not only the integration and promotion of the three-dimensional goal,but also the discipline and function.It is the basic role of the core literacy in the academic significance.The evaluation based on the core literacy of the subject should be different from the current evaluation mode based on paper and pencil test.How to find a suitable evaluation mechanism in the process of teaching practice becomes a difficult problem in the academic circle.The design of the understanding learning evaluation system provides a kind of New ideas for evaluation.This study aims to understand the construction of learning evaluation model,the pursuit of students' in-depth understanding of knowledge,select the "People's Education Edition High School Chemistry Elective 4" module,comprehensive analysis of core literacy education requirements,curriculum standards,teaching materials,academic conditions and other factors,to each The chapter is a large unit,refining the core concept,designing teaching objectives,evaluation goals and series of content situations with complex situations with small units per class hour,and setting three levels of six dimensions of understanding learning for situational problems.,develop corresponding evaluation criteria,and complete the construction of the learning evaluation system.This study takes situational problems as clues,mainly involving chemical concept situations,life situations,complex problem situations,social time situations and human history situations.By setting situational problems,the most students learn behavior changes to promote the implementation of core literacy.To this end,the teaching design case is used to explain how to deal with the relationship between teaching objectives and evaluation goals,embedding situational evaluation problems into the teaching process,and achieving the design of teaching evaluation integration.Through the implementation of performance evaluation,the implementation of implicit literacy such as emotional attitudes and values and the comprehensive cultivation of core literacy are promoted.
