Abstract: Objective To explore the effect of preview and interaction based on Rain Classroom in the course of speech and language therapy.Methods Factor analysis was used in the study. From September to December 2019, fifty-five four-year program students majoring in rehabilitation therapy from grade 2017 in China Medical University were selected. In the course of speech therapy, the Rain Classroom method was used for pre-class preparation and classroom interaction. The final score was used to evaluate teaching effect. The influence of pre-class preview and classroom interaction on the final score was analyzed by chi-square test and logistic analysis.Results Students whose preview pages of courseware and the preview test score were excellent have a higher rate of outstanding final scores[71.4%(20/28),70.0%(21/29)]than those preview pages of courseware and preview test scores were good[28.6%(8/28),30.0%(9/30)],The differences were statistically significant(all P<0.01). There was no statistically significant in the rate of excellent students [58.3%(14/24),41.7%(10/24)] with different grades of thinking questions in class interaction (P=0.28). So the number of pages of previewed courseware [OR (95%CI) =4.76(1.21-18.64), P=0.03] and the previewed test score [OR (95%CI) =6.46(1.32-31.72), P=0.02] are main factors to influence the final test score.Conclusions Pre-class preview based on Rain Classroom improves the final score and has a positive impact on the learning outcome of speech and language therapy course. The application effect of rain classroom-based interaction needs to be further explored.
