This study investigated the effects of 5E instructional model on the teaching processes of novice teachers. First, we conducted a teaching design training project based on the 5E model for 40 novice teachers, and compared pre-texts of the teachers' teaching process from before the training with post-texts obtained immediately following the training to determine whether the model can promote the teaching design process of novice teachers. In order to explore how the 5E model influenced the novice teachers' teaching processes, we chose three teachers for an additional three stages of training, then compared the texts resulting from the different stages and interviewed each teacher. Finally, we found that the 5E model had a significant effect on the improvement and further development of the teaching processes among the novice teachers. The model influenced the teachers' teaching process through each of the sub-phases, and different sub-phases resulted in different improvements. Each novice teacher also showed different improvements, with the specific improvements also being affected by teachers' personal beliefs.
