The research finding can be summarized as the following;

The teaching method "problem-based learningyy, in waster pollutants and analysis

. G

course is one of the suitable approach for implementing in the environmental science program.

Students have become intcrcsted and enthusiastic about water pollution problem in Mae Kha canal. They have learnt both laboratory practical skills and problems in the real situation. As a result, they have realized about how serious of the problem in Mae Kha canal.

All students have achieved the course assessment criteria. For students' learning improvement, the score of the post-test is higher than the pretest one at the .05 level of significance. Students learning by problem-baed learning method were satisfied towards problem-based learning at the high level, except in the aspect of equipment, chemicals and laboratory, the average satisf8ction was observed.
