Abstract
Indonesia is the second largest rubbish contributor to the sea in the world. The numbers are getting increased every year. Knowing the scientific representation on sea water pollution is believed as the educated campaign to prohibit the action. The purpose of the research was increasing students^ scientific representation through the implementation of guided research-based learning. The method was a pre-experiment with a one-group pretest-posttest design that involved seven graduated students in science experiment class at one of campus in Bandung. The instruments were four-tier diagnostic test on sea pollutant migration and the interview questions. Students^ answers were classified into several levels. Generally, the result showed that guided research-based learning improved students^ representation on sea water pollution from misconception level to lack of knowledge level even scientific conception level. This finding indicates that increasing scientific representation can be improved by implementing guided-research based-learning.
