Abstract-Physics learning has greatly contributed to the development of technology products. Why do most students face difficultly to design a product creatively? This paper describes the effectiveness of Creative Responsibility Based Learning (CRBL) to maximize the scientific process skill within creative product design. This research was conducted in four classes (physics, chemistry, biology, and science education) Universitas Lambung Mangkurat in 2016. Scientific process skill and creative product design data were obtained from the pre-test and post-test. The data were analyzed by using independent t-test, one-way ANOVA, Tukey test, and bivariate correlation. The tvalue of scientific process skill was -13.156 and the t-value of creative product design was -12.640. It indicated that the average of pre-test and post-test was significantly different. The CRBL affected students' scientific process skill and creative product design. Tukey test results also indicated that all groups had no significant difference with one another. F-value of scientific process skill was 1.236 with sig 0.315, indicated that CRBL increased scientific process skill consistently. F-value of scientific process skill was 3.483 with sig 0.018, indicated that CRBL increased creative product design consistently. Bivariate correlation test indicated that there was a correlation between scientific process skill and students' creative product design. The correlation was 0.511. It was concluded that CRBL was effective to maximize the scientific process skill within creative product design. Furthermore, it is recommended that the way to make creative product design is implemented in the daily life.
