About CBSE Curriculum PHYSICS Class 12
☞ PHYSICS Class 12 CBSE : At the senior secondary level of school education, there is a transition from general education to a discipline-based focus curriculum. The present updated syllabus has an in-depth disciplinary approach as well as the comprehension level of learners. Due care has also been taken that the syllabus is comparable to the international standards.
- Salient features of the syllabus include:
- Emphasis on basic conceptual understanding of the content.
- Emphasis on use of SI units, symbols, nomenclature of physical quantities and formulations as per international standards.
- Providing logical sequencing of units of the subject matter and proper placement of concepts with their linkage for better learning.
- Reducing the curriculum load by eliminating overlapping of concepts/content within the discipline and other disciplines.
- Promotion of process-skills, problem-solving abilities and applications of Physics concepts.
