In order to promote the effective application of intelligent teaching in modern teaching, this paper combines big data technology to build an educational information platform, integrates intelligent education into actual teaching. Moreover, this paper uses educational data related technology to judge and analyze it through technical level, so as to enhance the effectiveness of education. Moreover, the evaluation method proposed in this paper has changed from traditional evaluation based on teachers’ impression and experience of a single individual to data-based evaluation. The way of teaching evaluation no longer only depends on teachers’ evaluation of individual impression, but also depends on education big data related technologies to find a law of teaching activities and better optimize and improve the teaching process. From the experimental results, we can see that the education information platform based on big data proposed in this paper has a good improvement on the traditional online teaching mode.
