A Study On The Application Of Expressive Assessment In Elementary School Science

Performance assessment is an assessment method that requires students to apply their knowledge to solve a problem or complete a task in a real or simulated real situation,so as to examine the degree of mastery of students’ knowledge and skills,as well as their ability in problem solving,critical thinking and communication and cooperation.At present,the traditional paper-and-pencil test is the most used assessment method in elementary school science teaching in China,and the evaluation method of the traditional paper-and-pencil test has the disadvantage of focusing too much on knowledge transfer and is not conducive to the overall development of students’ comprehensive ability.The application of expressive assessment in elementary school science teaching is conducive to the cultivation of students’ higher-order thinking and the overall development of students’ comprehensive quality ability.Therefore,it is of great theoretical and practical significance to conduct research based on the application of expressive assessment in elementary school science teaching.This paper mainly adopts the research methods of literature research,questionnaire survey and case study.Based on the combing and analysis of related research results and the definition of core concepts,the main dimensions of the questionnaire survey were determined,a questionnaire survey on the current situation of the application of expressive evaluation in elementary school science teaching was prepared,and a questionnaire survey was conducted in elementary school J in X city.The current situation was analyzed in terms of teachers’ and students’ perceptions of expressive evaluation and the implementation status of expressive evaluation in elementary school science teaching,and the specific implementation process of expressive evaluation in elementary school science teaching was discussed in the context of the connotation and characteristics of expressive evaluation,and the implementation process and effect analysis of expressive evaluation were demonstrated through cases.The study found that the current status of the application of expressive assessment in elementary school science teaching is not optimistic.The main problems are: teachers do not know enough about the implementation strategies of using expressive assessment;students are willing to participate in expressive assessment but teachers implement expressive assessment less frequently;teachers use less expressive assessment of experimental inquiry type.The specific implementation process of expressive assessment in elementary school science teaching is mainly as follows: determining expressive assessment goals,designing expressive tasks,developing expressive assessment scoring rules and scoring scales,implementing expressive assessment and analyzing expressive assessment results.After embedding the implementation process of expressive assessment into specific cases and implementing it,the following implementation effects can be obtained:expressive assessment is beneficial to the development of students’ scientific knowledge level and scientific inquiry ability;it is beneficial to the improvement of students’ scientific thinking ability;and it is beneficial to reflect the whole process of students’ learning.
