Research On Evaluation Index System Of STEM Education Project In China

In the era of Internet economy,the social problems faced by human beings are becoming more and more complex and systematic,and the society has put forward an urgent demand for the cultivation of high-level innovative,compound and applied talents.STEM education advocates starting from real life problems,and aims to train students to use multidisciplinary knowledge to explore and solve problems,so as to improve students' comprehensive quality.With the increasing attention paid to STEM education in China,STEM education in the form of projects is becoming more and more common.How to evaluate STEM education projects has become the focus of researchers.Starting from the issue of STEM education project evaluation,this study investigated the research status of STEM education at home and abroad through literature,and then analyzed and summarized the evaluation subjects,evaluation objects,evaluation index content,evaluation method or process of the existing STEM education project evaluation index system abroad by using comparative research method.According to the CIPP project evaluation model,the index system is classified and analyzed.The key contents and characteristics of STEM education project evaluation are summarized from four aspects:context,input,process and product,which lays a good theoretical and practical foundation for later research.Based on the principles of construction and STEM education project design,and the current situation of STEM education project in China,the evaluation index system of STEM education proj ect is preliminarily constructed.On the basis of the proposed STEM project pre-evaluation framework,this study used Delphi method to determine the evaluation and scoring of the indicator system by multiple and authoritative expert groups,and adopted the boundary value standard method to screen the indicators,and modified them in combination with expert Suggestions until the expert opinions were consistent.Then,the analytic hierarchy process(AHP)is used to assign weights to the indicators at different levels.Finally,the evaluation index system and its weight of STEM education projects were determined,including 5 first-level indicators,14 second-level indicators and 3 7 third-level indicators.Based on the evaluation index system of STEM education project and the current situation of STEM education development in China,this paper puts forward three enlightenments for carrying out STEM project:attaching importance to STEM education in an all-round way,improving teachers'professional level and students' comprehensive quality;paying attention to every link of STEM project to ensure the rigor and effectiveness of activities;ensuring the completeness of learning resources and paying attention to project demonstration and quality.Extension.
