Research and Application of the Evaluation Model of Educational Technology Capability Based on BP Neural Network——Taking PBL Teaching Situation as An Example

摘要

PBL is based on teaching method, a situation based teaching process, which has been widely used in the teaching process since the 50 years of the last century. In this paper, it based on the BP neural network. The evaluation model of educational technology ability is studied and applied in the PBL teaching process. In the early stage, it based on the author's investigation and analysis of the students' educational technology ability. Then in the medium term, it based on the PBL teaching method, and the diagnosis and evaluation of learning were carried out. Later, it based on the establishment of evaluation model, testing and evaluation in order to promote the development of students' educational technology ability.
