Science education is a structured exploration of the natural world, extending beyond mere knowledge to nurture skills and dispositions critical for understanding and decision-making. Its interdisciplinary nature provides a holistic perspective, and it plays a pivotal role in addressing contemporary global challenges. With a progressive approach, it allows students to specialise and delve deeper into scientific disciplines as they advance in their education.


  1. Systematic Study: Science education is the structured exploration of the natural and physical world. It involves processes like observation, hypothesis formation, experimentation, evidence analysis, and knowledge refinement.
  2. Development of Skills and Dispositions: It goes beyond mere knowledge acquisition. Science education aims to nurture vital skills and dispositions like critical thinking, curiosity, creativity, evidence-based reasoning, and sound decision-making. These skills are not only beneficial for understanding the world but also for making informed choices that benefit individuals and communities.
  3. Interdisciplinary Nature: Science draws from a range of disciplines, including biology, chemistry, physics, earth sciences, mathematics, computational sciences, and sometimes social sciences and vocational education. This interdisciplinary approach provides a holistic understanding of the role of science in our daily lives.
  4. Addressing Contemporary Challenges: The NCF emphasises the role of science education in addressing current global challenges such as climate change, healthcare improvement, technological advancement for sustainability, equitable livelihood creation, and environmental harmony. It highlights the importance of preparing students to engage with and solve these challenges.
  5. Progressive Approach: Science education is designed to be progressive. It starts at an early stage with basic scientific principles and gradually becomes more in-depth as students progress through different educational levels.
  6. Specialisation and Depth: In the final years of secondary education (Grades 11 and 12), students have the opportunity to choose specific scientific disciplines such as physics, chemistry, biology, or earth science. This allows them to delve deeper into their chosen area of study and develop expertise.

The purpose of science education in schools, according to NCF 2023


Science, through systematic inquiry, unveils the world's mysteries. Science education equips individuals with vital skills such as critical thinking and evidence-based reasoning, enabling them to actively engage in society, challenge norms, and drive positive change.


  • Scientific Understanding: Develop a systematic understanding of the natural world.
  • Capacities for Scientific Inquiry: Build skills for hypothesis generation, analysis, and logical thinking.
  • Historical Context: Understand the evolution of scientific knowledge.
  • Interdisciplinary Connections: Recognise interlinkages between science and other disciplines.
  • Society and Science: Appreciate the societal impact and ethical aspects of science.
  • Scientific Temper: Foster critical thinking, scepticism, and ethical values.
  • Creativity: Encourage creativity in scientific exploration and problem-solving.

What can a proper science education provide students in schools?


  • Encouraging Creativity: Science education recognises that science is a creative process. It encourages students to imagine new ideas and concepts to better understand the world. This creativity is crucial for asking questions, forming hypotheses, conducting experiments, and creating models.
  • Providing Tools for Exploration: Science education equips students with the methods and tools they need to explore and understand the world. These tools help create explanations that are based on real-world evidence, which can be rigorously tested in various situations.
  • Embracing Change and Evolution: Students are taught that scientific knowledge is reliable but can change as new evidence emerges. Science education encourages an appreciation for the ever-evolving nature of scientific knowledge and the rigorous process through which it evolves.

Challenges mentioned in NCF 2023 in Teaching Science in Schools


1. Overemphasis on Facts: Science education has traditionally focused on facts and definitions from textbooks, leaving limited time for exploration and discussion. This content-heavy approach hinders the development of conceptual understanding and critical thinking, which becomes even more challenging as students advance to higher grades.

2. Curriculum Content: The content included in the curriculum is often influenced by the requirements of higher education entrance examinations. This doesn't align with the true aims of school education. There's a need to shift towards competency-based assessments rather than rote memorization.

3. Disconnect with Student Experiences: Students often come to school with preconceived ideas and observations that may conflict with scientific concepts. Bridging the gap between these personal theories and scientific knowledge is a challenge, particularly when common intuition contradicts established scientific principles.
4. Lack of Infrastructure: Access to laboratory equipment and materials is essential for effective science education. However, there is a persistent lack of infrastructure and resources in schools. Additionally, teacher capacity frequently hinders the creation of local, affordable teaching materials.


Curriculum of Science education according to NCF 2023


Middle stage

Based on the considerations outlined in NCF 2023, the concepts to be taught at the middle stage of science education are selected to align with students' concrete experiences and immediate environment. The essential concepts to be taught at this stage include those that:


1. Build on what students see around them.
2. Address common observations they make.
3. Incorporate aspects of science and technology relevant to their daily lives.
4. Address their immediate concerns.
5. Help students abstract 'Science' as the explanation for their observations and experiences.
6. Take into account how students learn best, and the capacities required for learning at this stage.
7. Foster the development of scientific values and dispositions.


These selected concepts are intended to provide a meaningful and relatable foundation for students, enabling them to connect their everyday experiences to scientific explanations and encouraging them to engage with science in a way that is relevant to their lives.


Secondary stage


According to NCF 2023, the concepts to be taught at the secondary stage of science education are designed to transition from concrete, perceptual, and practical concepts to more theoretical and abstract ones. The key concepts at this stage address the following questions and objectives:



1. Exploring the Unseen: Concepts that help students understand phenomena and events that cannot be directly observed
2. General Principles: introducing general principles that govern the world and explaining why events and phenomena repeat themselves.
3. Diversity and Reasons: Exploring the reasons for diversity in the natural world
4. Role of Science and Technology: Understanding the Role of Science and Technology in Society
5. Contribution of India: Recognising India's contribution to scientific knowledge
6. Application of Science: Exploring how science can be applied in various areas and its connections to other disciplines
7. Scientific Practice: Emphasising how science should be practised
8. Scientific Values and Dispositions: Developing scientific values and dispositions
These concepts are aimed at enabling students to engage with abstract and theoretical aspects of science, empowering them to understand and explain complex phenomena, apply scientific principles, and develop the foundational skills necessary for scientific exploration and problem-solving.


Pedagogical Approaches in Science Education given in NCF 2023:



1. Hands-on Science: The primary emphasis is on experiential learning, where students actively engage in practical experiments and activities. They gain conceptual understanding by manipulating materials, designing experiments, and building demonstrations.
2. Discovery Approach: Students explore the natural world based on their interests and make their own discoveries. Teachers may guide them by drawing attention to specific phenomena. This approach encourages students to connect their observations to scientific concepts.
3. Inquiry Approach: Students work like scientists, navigating unknown questions and exploring solutions independently. It involves systematic observation, experimentation, inference, and communication. Teachers provide support as needed and choose the appropriate level of inquiry.
4. Project-Centred Approach: Learning extends beyond the classroom and over time. Students undertake projects that require in-depth exploration and connection to daily life. They create artefacts that reflect their understanding, fostering the integration of concepts from various curricular areas.
5. Didactic Approach: This approach involves structured teaching, where teachers convey important scientific information, terms, and the historical development of concepts. Teachers guide the flow of the lesson, especially when explaining fundamental principles.
6. Demonstration: Teachers demonstrate the working of instruments or experimental set-ups to illustrate key concepts. These demonstrations enrich students' learning experiences and help them understand scientific principles through visual examples.



Assessment in science education, according to NCF 2023



1. Understanding of Concepts: Assessment should evaluate students' grasp of scientific concepts and their ability to apply the scientific method. This includes observing, questioning, hypothesising, predicting, conducting experiments, collecting data, inferring, analysing, making decisions, and evaluating outcomes.

2. Diverse Assessment Methods: Students should be assessed using a variety of methods, including answering questions, designing and conducting experiments, creating models, and engaging in debates and discussions. This ensures a well-rounded evaluation that goes beyond traditional written tests and encourages active participation and practical application of scientific knowledge.

NCF 2023 reimagines science education as a dynamic journey for students. It emphasizes the development of critical skills and dispositions, the interdisciplinary nature of science, and its role in addressing global challenges.
