Fifty Years of Educational Value-added Assessment:Evolution,Challenges,and Approaches
Educational Value-added assessment started in the United States in the 1960s and has gone through the evolutionary path of ideological germination,practical application,and in-depth development.It was intro-duced in China in the 1990s and has gone through the stages of reflection,small-scale research practice,and extensive exploration.Educational value-added assessment has progressed in concept,technology,and applica-tion.However,there are still many practical problems and challenges in how to develop value-added assess-ment in China:conceptually,there is a controversy over whether value-added assessment is value-added for students or for education,as well as the difference in understanding of whether value-added assessment is a simple increment or a difference in the principle of difference between the expected level and the actual level af-ter considering the background;technically,it faces a dilemma between the ideal pursuit of obtaining the"net effect"of value-added through value-added models and the difficulty of achieving the actual restrictive evalua-tion conditions;in terms of application,value-added evaluation still faces the application dilemma of the whole process of evaluation content selection and material(data)collection,method and technology selection and re-sult use,and also needs to solve the problem of balanced development of value-added evaluation in urban and rural areas,regions,schools and different levels of education.Facing the future,China needs to deepen the un-derstanding of the development trend of value-added assessment,clarify the future path,and promote the con-struction process of the Chinese model of value-added assessment:firstly,deepening the understanding of the theory of value-added assessment and promote the professional development of value-added assessment;sec-ondly,deepening the understanding of the function of evaluation combination and promote the scientific devel-opment of value-added assessment;thirdly,deepening the understanding of the evaluation empowered by tech-nology,and promoting the wisdom of value-added assessment;finally,deepening the understanding of being based on practice and rooted in China to promote the localized development of value-added assessment.
