Abstract: 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. Keywords: content knowledge, chemistry in the vocational context, preservice chemistry teachers, petroleum, polymers PEMBELAJARAN KOLABORATIF UNTUK MENINGKATKAN PENGETAHUAN KONTEN KIMIA KONTEKS KEJURUAN OTOMOTIF CALON GURU KIMIA Abstrak: Penelitian ini bertujuan untuk mengkaji efektivitas pembelajaran kolaboratif berbasis pemecahan masalah dalam meningkatkan pengetahuan konten kimia konteks kejuruan otomotif.

The teacher is an essential component of learning. Learning that is often focused by the government is learning in urban schools. Even though rural schools also have the same right to consider. Longer distances and access to schools that are more difficult to reach causes a lack of attention in rural areas schools. Learning in rural areas also requires attention to improve the quality of teaching. Knowing learning activities in rural schools is very important because it will understand what learning needs to be improved. The purpose of the research is to find out how teaching science in rural schools. This research uses mixed methods with the Taxonomy Development Model research design. The phase of QUAL is carried out to identify important variables. The development of a taxonomy or classification system, the development of theories that are not yet stable, and supporting it is a test in the phase of QUAN to obtain more thorough study results. The findings of this study illustrate that learning begins with answering questions, so students are enthusiastic. The next learning activity showing films about the reproduction of students was very excited about learning. The obstacle found in learning is the lack of preparation in the learning that is done so that time is wasted to condition the video playback.

The lack of didactic anticipation as reflected in lesson plans can have an impact on the less optimal learning process for each student so that learning obstacles arise. One effort to overcome this is to design learning through didactic design. This study aims to develop a didactic design in reducing learning obstacles in the concept of redox reactions. The method used in this research is a qualitative research method. The research design used is Didactical Design Research (DDR). Data collection techniques used are tests, observations, interviews and documentation. Respondents in this study were 30 students of the UPI Pilot Laboratory High School in class XI IPA 2 and 28 students in class X. Based on the results of the study, it was found that the didactic design developed in the form of Chapter Design and Lesson Design included providing an understanding of concepts through the provision of phenomena followed by experiments or demonstrations in general, which ran smoothly. The existence of Chapter Design and Lesson Design components aims to make students obtain the material. The other goal is to make it easier for teachers to achieve better educational goals by bringing out predictions of student responses and prepared teacher anticipation. This didactical design can reduce learning barriers and can improve students' abilities. It can be concluded that the didactic design of the concept of oxidation-reduction reactions is effective as an alternative teaching material used in the learning process.
