CBSE Class-12 Syllabus 2018-19 (Chemistry)

Posted: 31 Mar 2018 01:20 AM PDT

CBSE-CLASS-12-LOGO

CBSE Class-12 Syllabus 2018-19 (Chemistry)

Rationale

Higher Secondary is the most crucial stage of school education because at this juncture specialized discipline based, content -oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry with a purpose of pursuing their career in basic sciences or professional courses like medicine, engineering, technology and other applied areas. Therefore, there is a need to provide learners with sufficient conceptual background of Chemistry, which will make them competent to meet the challenges of academic and professional courses after the senior secondary stage.

The new and updated curriculum is based on disciplinary approach with rigour and depth taking care that the syllabus is not heavy and at the same time it is comparable to the international level. The knowledge related to the subject of Chemistry has undergone tremendous changes during the past one decade. Many new areas like synthetic materials, bio -molecules, natural resources, industrial chemistry are coming in a big way and deserve to be an integral part of chemistry syllabus at senior secondary stage. At international level, new formulations and nomenclature of elements and compounds, symbols and units of physical quantities floated by scientific bodies like IUPAC and CGPM are of immense importance and need to be incorporated in the updated syllabus. The revised syllabus takes care of all these aspects. Greater emphasis has been laid on use of new nomenclature, symbols and formulations, teaching of fundamental concepts, application of concepts in chemistry to industry/ technology, logical sequencing of units, removal of obsolete content and repetition, etc.

Objectives

The curriculum of Chemistry at Senior Secondary Stage aims to:
• promote understanding of basic facts and concepts in chemistry while retaining the excitement of chemistry.
• make students capable of studying chemistry in academic and professional courses (such as medicine, engineering, technology) at tertiary level.
• expose the students to various emerging new areas of chemistry and apprise them with their relevance in future studies and their application in various spheres of chemical sciences and technology.
• equip students to face various challenges related to health, nutrition, environment, population, weather, industries and agriculture.
• develop problem solving skills in students.
• expose the students to different processes used in industries and their technological applications.
• apprise students with interface of chemistry with other disciplines of science such as physics, biology, geology, engineering etc.
• acquaint students with different aspects of chemistry used in daily life.
• develop an interest in students to study chemistry as a discipline.
• integrate life skills and values in the context of chemistry.

CBSE-CLASS-9-LOGO

CBSE Class-9 Syllabus 2018-19 (Social Science)

Rationale

Social Science is a compulsory subject upto secondary stage of school education. It is an integral component of general education because it helps the learners in understanding the environment in its totality and developing a broader perspective and an empirical, reasonable and humane outlook. This is of crucial importance because it helps them grow into well-informed and responsible citizens with necessary attributes and skills for being able to participate and contribute effectively in the process of development and nation- building.
The Social Science curriculum draws its content mainly from Geography, History, Political Science and Economics. Some elements of Sociology and Commerce are also included. Together they provide a comprehensive view of society-over space and time, and in relation to each other. Each subject’s distinct methods of enquiry help the learners to understand society from different angles and form a holistic view.

Objectives

The main objectives of this syllabus are:
• to develop an understanding of the processes of change and development-both in terms of time and space, through which human societies have evolved.
• to make learners realise that the process of change is continuous and any event or phenomenon or issue cannot be viewed in isolation but in a wider context of time and space.
• to develop an understanding of contemporary India with its historical perspective, of the basic framework of the goals and policies of national development in independent India, and of the process of change with appropriate connections to world development.
• to deepen knowledge about and understanding of India’s freedom struggle and of the values and ideals that it represented, and to develop an appreciation of the contributions made by people of all sections and regions of the country.
• to help learners understand and cherish the values enshrined in the Indian Constitution and to prepare them for their roles and responsibilities as effective citizens of a democratic society.
• to deepen the knowledge and understanding of India’s environment in its totality, their interactive processes and effects on the future quality of people’s lives.
• to facilitate the learners to understand and appreciate the diversity in the land and people of the country with its underlying unity.
• to develop an appreciation of the richness and variety of India’s heritage-both

• to promote an understanding of the issues and challenges of contemporary India-environmental, economic and social, as part of the development process.
• to help pupils acquire knowledge, skills and understanding to face the challenges of contemporary society as individuals and groups and learn the art of living a confident and stress-free life as well as participating effectively in the community.
• to develop scientific temper by promoting the spirit of enquiry and following a rational and objective approach in analysing and evaluating data and information as well as views and interpretations.
• to develop academic and social skills such as critical thinking, communicating effectively both in visual and verbal forms- cooperating with others, taking initiatives and providing leadership in solving others’ problems.
• to develop qualities clustered around the personal, social, moral, national and spiritual values that make a person humane and socially effective.
