Teacher Development

1. Preamble

The journey of Information and Communication Technology in Indian school education started through National Policy on Education in India in the year 1984-1986, modified in 1992, stressing the need to include technology in school education to improve the quality of education. This policy led to two central schemes for ICT and Education in 2004, revised in 2010, focusing mostly on computer literacy and Computer Aided Learning.

Reforms in assessments have been extensively deliberated in India. National policies and commissions before Independence, such as the Hartog Committee (1929) and Sargent Plan (1944) as well as those post-independence such as the Mudaliar Commission (1953), Kothari Commission (1964), National Policy on Education (NPE) 1968 and ‘86, Learning Without Burden (1993) and National Curriculum Framework (NCF) 2000 and 2005 have recommended changes in the examination system.

Living organisms can be studied at different levels of organization — from molecules to ecosystems. Our current understanding of chemistry sheds some light on the way we understand living organisms at each of these levels. This article offers a glimpse of some interesting aspects of ‘life’ through the lens of chemistry.

While walking through a beautiful garden, you are met with a lovely bouquet of fragrances from its many flowers. These smells are so pleasing that we use them in our homes, food, and even on our bodies.
