Abstract:
Problems encountered are too difficult for students to understand organic chemistry,
including stereochemistry, organic reaction synthesis. So, we need a way to overcome this
problem in order to increase the quality of learning processes through the implementation of the
multimodel Computer Support Collaboration Learning-Retrosynthetic Analysis (multimodel
CSCL-RA) in organic chemistry. This study is action research with descriptive qualitative
approach with students of Organic Chemistry III in Chemical Education Program, ULM. Thirty
pair dyads of students participated in a problem task. The instrument of research was in the form
of problem-solving ability and cognition test instrument, observation sheet of teacher and student
activity. Data were analyzed using percentage of students’ problem-solving ability and
achievement. The results showed that the implementation of CSCL-RA multimodel in organic
chemistry increased the quality of learning with indicators of increasing students' problemsolving
abilities and learning outcomes. The implication for future research could provide
further: (1) students’ interactions in CSCL, (2) CSCL with metacognitive training in problemsolving.
