This study was aimed to examine the effectiveness of collaborative problem-solving-based learning to improve knowledge about chemistry content in the automotive vocational context. The study design used was one-group pretest-posttest design and applied to Vocational Chemistry subjects. Data analysis was performed by using the normalized gain-test formula and t-test using SPSS software version 21. The findings showed that collaborative learning is effective to improve pre-service teachers’ knowledge about chemistry content of petroleum and polymer chemistry. The mastery level of basic knowledge about the petroleum and polymers is fairly good. However, the knowledge of the content of petroleum and polymer applications in the automotive field is not satisfactory. Although the application content knowledge increased with the moderate criterion for the application of petroleum and with the low criterion for polymer applications, the mastery level of pre-service teachers at the end of the course was still low. Factors that allegedly become the causes of the low mastery of application content knowledge are the characteristic factor of the content, conceptual learning difficulties and the experience factor.
