Training of KRPs to Strengthen Numerical Problem soIving Skills in Chemistry at Senior Secondary School Level

Abstract

Chemistry is molecular in natural and is intimately related with Physics and Biology. Its nature is highly abstract. The molecular interactions are studied in terms of color change, change in pressure and temperature, change in mass of reactants and products, etc. Due to the advancement of science many more theories have emerged to explain the various phenomenons in chemistry. However, understanding of a theory remains incomplete if one does not understand its application. The quantitative i.e. aspect of a theory in terms of numerical problem helps the learner to assimilate the theory is better way. Hence a chemistry student must develop a positive attitude towards solving numerical problems. This programme was formulated to provide additional pedagogical inputs to senior secondary chemistry teachers, particularly of Biological science background to develop the skill of solving numerical problems. Once the teachers are pedagogically strengthened then the idea would be percolated in classroom teaching, and ultimately students would be benefited.
