Is school Science in search of democratic order?

Science is all around us. We see science in all our day to day activities. The functions which science has to perform in the curriculum. is that it has to open intellectual vistas and create an awareness of science and its application.

Pure science is not totally different from practical science (or) laboratory science, Indian exam curriculum obstructs learning science in the correct perspective. Students who complete their school, college education and start their life in industry are not fully prepared for it. Our present Indian curriculum emphasises more on acquiring facts and recall, rather than its application. That is why, Indian students face difficulty when they actually start their career.

"Pure science is fit for the superior mind. in the liberal curriculum for the higher orders and simultaneously a halt to practical scientific education of the lower order."

At the high scool level connecting the scientific facts to day to day activities and its application can be to some extent explained. For example. while teaching chromatography(amethod of separation), application of this separation method is explained in terms of analysis in biotech industries and in forensic sciences.

High school student s are taught to design experiments. For example to study the rate of chemical reactions, they have to relate to the factors which influence rate of reactions. Especially while teaching chemistry, practical applications in the laboratory and connecting to the theoritical knowledge has greater impact on their learning.

For a particular content different contexts can be established, which helps in their learning better. For example while learning atomic spectra, the emission spectra phenomenon can be explained by flame test in the laborotory, it can be contextualised with its application in the metallic vapour lamps.
There are are so many misconceptions inlearning chemistry. In the high school level when they learn about dissolution of solids in liquids, students are often mislead to understand that the intermolecular space between the liquid molecules is occupied by solute particles, which is not true. Dissolution is produced through the interaction between the solute and the solvent, which they can understand for themselves by studying the physical properties of the pure solvent and the solution.

  • i like it so far but it's incomplete hema. how do you link the essay with the title?

  • Good start, Hema. You have described some ideal scenarios for good science teaching. You now have to relate this not only to the article (as Koshy rightly suggested) but also to your current classroom practice and how certain aspects of the 'context of your practice' (such as exams) may be coming in the way of the execution of these ideal scenarios and how you would strike the balance. Good Luck!
