Abstract: An online teaching tool "rain classroom" was applied to the reform of the evaluation system of the medical genetics course. The formative assessment was strengthened while the summative assessment was well completed. Multiple methods were used, including preview, attendance, answering questions in class, stage quiz, case-base leaning, homework, final exam and so on. Quantitative evaluation of teaching in class and autonomous learning after class covered from learning attitude through learning result. The post-class questionnaire showed that the degree of satisfaction was high and the comprehensive evaluation system could effectively promote autonomous learning.

Key words: Medical Genetics teaching, Rain Classroom, formative assessment, autonomous learning
