Abstract: Constructing the evaluation indicator system of college teachers' engineering expertise scientifically is not only related to the practical path of the development of emerging engineering teachers,but also can effectively improve the quality of engineering education personnel training.From the perspective of embeddedness theory,teachers' engineering expertise is influenced by four dimensions of the teacher individual cognition,students' engineering quality,universities' education goal of engineering and social demand of engineering.The correlation of the four dimensions is both foundation of interpretation model of teachers' engineering expertise and the basic index of the evaluation of teachers' engineering expertise.Based on the the analysis of the embedded elements of teachers' engineering expertise,we construct the target layer,criterion layer and index layer of evaluation indicator system of college teachers' engineering expertise.
