Examples:
1. Biology : The study of biology begins as a study of living things/ organisms (plants, human, animals, micro-organisms etc), their life processes as well their interactions with the environment.
Biology can divided into few main areas such as botany, zoology, anatomy, genetics and ecology .
2. Chemistry : the study of chemistry begins as a study of the changes in matter (related to properties, structure, composition and reactions between atoms, ions, elements and substances) which are followed by changes in energy.
Chemistry can be divided into few main areas such as bio chemistry, physical chemistry, organic and inorganic chemistry.
3. Physics : the study of physics begins as a study of natural phenomena and an attempts to explain it scientifically.
Physics can be divided into two main areas ie classical physics (deals with matter, motion and energy ) and modern physics ( deals with atomic, nuclear, particle physics).
4. Mathematics : the study of mathematics begins as a study of numbers, shape and relations.
Mathematics can be divided into two main areas ie pure mathematics and applied mathematics.
Mathematics developed as a body of knowledge and it can be seen from 4 perspectives : language, science, a way of thinking and as a tool for problem solving.
5. Technology : the study of technology begins with the application of science to practical human needs ( ie increase productivity, improve quality of life etc) in agriculture, engineering, manufacturing, transportation, communication, medicine etc.
Discuss the importance of epistemology of knowledge in teaching and learning of science and mathematics.
