The Learning of Science-Based Laboratory Experiments to Improve the Student's Scientific Attitudes on Optical Materials

Abstract

The research on the application of lesson studies on Physics Subjects to improve the students' scientific attitudes on optical materials through the science-based learning laboratory experiments. The techniques and instruments of data collection in this study is by the observation and documentation. The application of lesson studies of each cycle consists of Plan, Do, See and redesign and all are done in three learning cycles, open class 1 the light refracting material on convex lenses. Open class 2 the reflectance material on a concave mirror. Open class 3 the light reflecting material on a convex mirror. Based on the results of the study found that the application of lesson study through science-based learning laboratory experiments is very effective to improve some indicators of students' scientific attitudes such as the attitude of asking the new things that have not been known when studying physics; Doubting the friends findings; thorough in experimenting; using the different tools in the investigation process; showing the different observation reports with friends, and cooperating and participating actively in groups. The high curiosity makes the students more severe in learning so that the sense of participation of each other in the group is active and the activities can be well exposed and increased.
