I. Introduction of NEB Biology Syllabus
NEB Biology Syllabus, being the science of nature, deals with the fascinating changes, which continuously take place in the living world. Every person is expected to understand the nature of which hi is a part. One needs to be familiar with the changes taking place in nature. The study of biology equips an individual, to understand the living world in the light of new researches. Besides realizing the general objectives of any discipline of science like the development of scientific temper and analytical skill, the curriculum in biology has also to be geared to meet the requirement of careers in the field of medicine and related disciplines (wildlife, forestry, agriculture, natural resources, environment, etc). This course is designed for general science (Biological and physical) students of Grade XI.
II.General objectives of NEB Biology Syllabus
The general objectives of NEB Biology Syllabus are,
a. to provide the concept of biology and encourage the learners to use the acquired knowledge in day to day life,
b. to make the learners aware of the present development in biological science as well as to develop the knowledge and skill in the wise use of the available natural resources and sustaining them; and
c. to prepare the students to take up advanced studies in biology at the university level.
III. Specific Objectives of NEB Biology Syllabus
On completion of the course mention in NEB Biology Syllabus the students will be able to:
1.describe the life components, the origin of life and its evolution up to the present day;
2.explain the cell components, their types, and cell division
3.explain diversity of plant and animal
4.discuss functional processes of the typical animal types
5.describe the environmental concept, ecological imbalances and their consequences; and
6. explain the importance of natural resources, their conservation, and management with reference to the national context.
