What is SIOP Model

By using video feedback as a treatment, this quasi-experimental study is aimed to capture the dynamic evolution process of teacher candidates' belief of comprehensible input. It compares the changes in teacher candidates' belief of comprehensible input among different feedback groups. A mixed method, which contains the pre and post surveys, semi-structured interviews, and micro-teaching assignments decoding, is used to boost the internal validity of the research design. An ANCOVA analysis was conducted through controlling different co-variances. The results suggest that after the treatment there is no statistically significant difference in teacher candidates' post-treatment belief of comprehensible input. This result is aligned with the patterns that were generalized from semi-structured interviews: 1) a lack of changes in the teacher candidates' belief of comprehensible input after receiving feedback, 2) an alignment between the teacher candidates' micro-teaching performances and their belief of comprehensible input, and (3) the teacher candidates' positive perceptions of the video feedback.
