Article history Abstract Submission : 2018-02-20 Revised : 2018-03-07 Accepted : 2018-03-08 Pedagogical Content Knowledge (PCK) development of appropriate chemistry in vocational context is necessary to prepare the capability of pre-service chemistry teachers in designing effective chemistry learning in vocational schools. This study aims to assess the self-efficacy pre-service chemistry teachers by the learning based on PCK development in vocational context. Pretest-posttest control group design was used in these research. The results showed that the PCK development strategy in the vocational context is able to increase selfefficacy of pre-service chemistry teachers. Most of pre-service chemistry teachers have increased self-efficacy, although some of preservice teachers have decreased self-efficacy. The main implication of this research is the need for restructuring of the curriculum for preservice chemistry teacher education programs that are more concerned with professional development in the context of vocational schools. .
