Higher Secondary is the most important stage of school education because, at this position specialized discipline-based, content-oriented courses are offered. Students reach this stage after 10 years of general education and opt for Chemistry to pursue their career in basic physics or expert courses like medicine, engineering, technology, and other applied areas.
Therefore, there is a need to give learners with enough conceptual background in Chemistry, which will make them able to meet the challenges of academic and expert courses after the senior secondary stage. The new and updated curriculum is based on a disciplinary approach with rigor and depth taking care that the syllabus is not heavy and at the same time it is similar to the international level.
The knowledge linked to the subject of Chemistry has experienced tremendous changes during the past decade. Many new areas like synthetic materials, biomolecules, natural sources, industrial chemistry are coming in a big way and deserve to be an essential part of the chemistry syllabus at a senior secondary stage.
At the international level, new formulations and classification of elements and compounds, symbols, and units of physical measures floated by accurate bodies like IUPAC and CGPM are of immense importance and need to be included in the updated syllabus. vocabulary, symbols, and formulations, the teaching of basic concepts, application of concepts in chemistry to business/ technology, logical sequencing of units, removal of antiquated repetition, etc.
