The Design Of Chemistry Learning Situations For Evaluating Core Literacies

Under the background of the new curriculum reform,it clearly puts forward the cultivation and requirements of students' core quality.However,how to evaluate and implement students' core quality has become the top priority of the curriculum reform.In the past,most of the evaluation is based on the test results to assess students' knowledge level,but the level of performance cannot assess students' ability and achievement of core quality.In order to implement the "integration of teaching,learning and evaluation" and put the core qualities into practice,the reform of the evaluation system is the core problem of the reform.Innovation point of this study was a complex situation problem set,in chemistry for high schools are taking five basic organic chemistry as an example a highly concise out of the core concepts of the organic chemistry "structure determines the nature",and for small units to each class teaching goal and the content of the problem,with complex situation and borrow cheer perkins understanding of learning six dimensions and the corresponding evaluation standard for tools to complete the construction of learning evaluation system.Through this research,the following conclusions are drawn:using the six dimensions of understanding learning can better achieve the implementation of core literacy,and setting up multiple situational problems under the six dimensions.Situation problem set contains the life situation,idea situation,social current situation,a complex problem situation and the historical and cultural situation of 5 major categories,is the current new curriculum core literacy training for the new train of thought,the idea of the students contact,emotion and thinking by situational questions and outside manifestation,and comprehensive evaluation for students.
