An experimental design was carried out to study the effectiveness in learning of the tenth grade students in Physics, when taught through online and face to face. A mash-up of different online tools and learning environment is used for the study.  Website ‘Wiziq.com’ provides these online tools and learning environment hence it is used for the study of effectiveness of online learning on students’ achievement. A high score in achievement among students taught and studied through online tools and online learning environment was found through this research. Similarly achievement among students of face to face teaching was found low, this is because in face to face learning, collaborating and sharing of resources is limited to the walls of classroom, but online learning made possible to learning, collaborating, and sharing of resources beyond four walls. Online learning provides the features such as, user centre, user control and communication, and making teaching learning process learner centric.
