Effectiveness of a Phonics Instructional Guide on the PCK of Teaching Phonics among Pre-service EFL Teachers

Previous studies have revealed that a newly compiled phonics instructional guide was able to improve the content knowledge level of pre-service EFL teachers by 23 per cent. Based on this and to further investigate how this guide indirectly impacted the pedagogical content knowledge of these teachers, a longitude and continuous quantitative study was conducted on the same sample in the same teaching college in China. In total, 140 pre-service EFL teachers were assigned to two equivalent groups as before, namely the experimental (N=70) and control groups (N=70), who conducted a trial phonics instruction and completed self-evaluation questionnaires, respectively. The trial instruction aimed to assess their pedagogical content knowledge of teaching phonics, while the self-evaluation form aimed to investigate their self-perceived competencies and efficacy in phonics instruction. The results indicated that based on the content knowledge they already possessed, the pre-service EFL teachers in the experimental group had higher levels of pedagogical content knowledge and self-perception; in comparison, those in the control group had lower pedagogical content knowledge and self-perception levels. In other words, the linear regression results demonstrated that the content knowledge of pre-service EFL teachers is a reliable predictor of their pedagogical content knowledge and self-perception levels. These findings suggest the necessity of enhancing pre-service EFL teachers’ content knowledge of phonics instruction via the guide to further improve their phonics instruction competency, which forms part of their pedagogical content knowledge.
