Activity Based Learning (ABL) is based on Cognitive theory of Knowledge and Learning. Learning from this perspective is understood as a self-regulated process. ABL provides an avenue to integrated learning within the students’ knowledge and activities to provide rich Educational experiences with Sensory experiences. Due to rapid development in science and technology our daily life has been affected greatly, Chemistry is a subject area whose study at the high school level will create a better understanding among students about the processes and products that are involved in our daily activities. Our teaching methods are still teacher centered, not student centered and do not encourage students to achieve life long learning and understanding. The purpose of the present study was to examine the Effect of ABL on Academic achievement of higher secondary school students in the subject of chemistry. The experiment was carried out by various activities like Quiz, Roulette wheel, Worksheets, Word search etc. Present study follows a “Soloman Four Group design”. Researcher used random sampling technique for selecting the sample and used various statistical techniques for data analysis. The paper discusses further details about the experiment.

Key words: Activity Based Learning, Academic Achievement, Effectiveness etc.
