Abstract

This research aims to enhance the students' comprehension and engagement on the Sound
Waves and Light Waves, using the Problem-based Learning (PBL) method combined with the learning
style-integrated worksheet. This research applies Classroom Action Reaearch (CAR) as the method, in
line with Kemmis & Mc Taggart in two cycles in which are planning, action I, observing I, reflecting I,
planning, action II, observing II, and reflecting II. The subject of this study are 35 students, 13 male and
22 female. The data were obtained by using observation, two tiers test, and documentation. The result
shows as follows: 1) The students' physics comprehension increases. The average percentage of the
students comprehension from the cycle I and cycle II are 84.1% and 84.3%, the misconception are 11.3%
and 11.6%, while the incomprehensive are 4.4% and 4.1%. The students' comprehension development
