The Effectiveness of Discovery Learning to Improve Observation Skill and Mastery of Concept of Chemical Equilibrium. This study aims to describe the effectiveness of discovery learning model to improving the observation skill and mastery of concept chemical equilibrium. This research was conducted at SMAN 15 Bandar Lampung Teaching Year 2018/2019 using quasi experimental method with Pretest Postest Control Group Design. Sampling of purposive sampling of 3 population classes and samples selected class XI Science 2 as experiment class and XI Science 3 as control class.
