Automatic Assessment Model for Content of Teaching Reflection
摘要
Abstract
Self-reflection is an effective way in teachers' professional development. How to evaluate the content of self-reflection automatically is a critical issue in the web-based software system. The content of self-reflection submitted under web environment is pre-processed such as Chinese word segmentation, stop words filtering and so on, build self-reflection text vector with vector space model, calculate the similarity between self-reflection text and corpus text based on cosine theory. According to the level of corpus text with maximum similarity and previous threshold of system,achieve the automatic evaluation of self-reflection content. The experiment shows that the correct rate of the automatic evaluation result is more than 90% compared with the expert evaluation result,implement the automatic assessment of self-reflection content well.关键词
