The focus of this paper is to examine constructivist approach using Virtual lab for concepts and cognitive development. Chemistry is one of the fundamental natural subjects which involve the study of universal law and the behaviors and relationship among a wide range of physical concepts and phenomena. Experiments are the prime in Chemistry. Scientific attitude and vision can be developed by providing opportunities to young minds to perform experiments in lab through constructivism approach. In present scenario, influence of constructivism in Chemistry teaching based on Virtual lab method is emerging as one of the most effective innovative approach. The present study is conducted to know that two common dimensions of change in learning style that emerged in Chemistry teaching: describing the nature of students’ alternative conceptions, the ways of changing cognitive structure, and cognitive aspects of learning and teaching Chemistry and provides guidelines for teachers, at all levels . Both dimensions relate to shifts in pedagogical paradigms that appear to be prerequisites to effectively using Virtual lab to promoting conceptual development. Our findings indicate that these shifts must not just occur at the teacher level, but must take hold throughout the educational system. The paper reports upon constructivism approach that promotes conceptual development when studying separation of mixture , using Virtual lab. The study involved a total of 102 prospective Chemistry students.
