1. Introduction
Mathematics is an indispensable in many fields. It is essential in the field of engineering, medicine, natural sciences, finance and other social sciences. The branch of mathematics concerned with application of mathematical knowledge to other fields and inspires new mathematical discoveries. The new discoveries in mathematics led to the development of entirely new mathematical disciplines. School mathematics is necessary as the backbone for higher study in different disciplines. Mathematics curriculum at secondary level is the extension of mathematics curriculum offered in lower grades (1 to 10).

This course of Mathematics is designed for grade 11 and 12 students as an optional subject as per the curriculum structure prescribed by the National Curriculum Framework, 2075. This course will be delivered using both the conceptual and theoretical inputs through demonstration and presentation, discussion, and group works as well as practical and project works in the real world context. Calculation strategies and problem solving skills will be an integral part of the delivery.
This course includes different contents like; Algebra, Trigonometry, Analytic Geometry, Vectors, Statistics and Probability, Calculus, Computational Methods and Mechanics or Mathematics for Economics and Finance.
Student’s content knowledge in different sectors of mathematics with higher understanding is possible only with appropriate pedagogical skills of their teachers. So, classroom teaching must be based on student-centered approaches like project work, problem solving etc.

6. Learning Facilitation Method and Process
Teacher has to emphasis on the active learning process and on the creative solution of the exercise included in the textbook rather than teacher centered method while teaching mathematics. Students need to be encouraged to use the skills and knowledge related to maths in their house, neighborhood, school and daily activities. Teacher has to analyze and diagnose the weakness of the students and create appropriate learning environment to solve mathematical problems in the process of teaching learning. The emphasis should be given to use diverse methods and techniques for learning facilitation. However, the focus should be given to those method and techniques that promote students’ active participation in the learning process. The following are some of the teaching methods that can be used to develop mathematical competencies of the students:
- Inductive and deductive method
- Problem solving method
- Case study
- Project work method
- Question answer and discussion method
- Discovery method/ use of ICT
- Co-operative learning
7. Student Assessment
Evaluation is an integral part of learning process. Both formative and summative evaluation system will be used to evaluate the learning of the students. Students should be evaluated to assess the learning achievements of the students. There are two basic purposes of evaluating students in Mathematics: first, to provide regular feedback to the students and bringing improvement in student learning-the formative purpose; and second, to identify student’s learning levels for decision making.
a. Internal Examination/Assessment
i. Project Work:
Each Student should do one project work from each of eight content areas and has to give a 15 minute presentation for each project work in classroom. These seven project works will be documented in a file and will be submitted at the time of external examination. Out of eight projects, any one should be presented at the time of external examination by each student.
ii. Mathematical activity:
Mathematical activities mean various activities in which students willingly and purposefully work on Mathematics. Mathematical activities can include various activities like (i) Hands-on activities (ii) Experimental activities (iii) physical activities. Each student should do one activity from each of eight content area (altogether seven activities). These activities will be documented in a file and will be submitted at the time of external examination. Out of eight activities, any one should be presented at the time of external examination by each student.
iii. Demonstration of competency in classroom activity:
During teaching learning process in classroom, students demonstrate 10 competencies through activities. The evaluation of students’ performance should be recorded by subject teacher on the following basis.
· Through mathematical activities and presentation of project works.
· Identifying basic and fundamental knowledge and skills.
· Fostering students’ ability to think and express with good perspectives and logically on matters of everyday life.
· Finding pleasure in mathematical activities and appreciate the value of mathematical approaches.
· Fostering and attitude to willingly make use of mathematics in their lives as well as in their learning.
iv. Marks from trimester examinations:
Marks from each trimester examination will be converted into full marks 3 and calculated total marks of two trimester in each grade.
The weightage for internal assessment are as follows:
| Classroom participation | Project work / Mathematical activity | Demonstration of competency in classroom activity | Marks from terminal exams | Total |
|---|---|---|---|---|
| 3 | 10 | 6 | 6 | 25 |
b. External Examination/Evaluation
External evaluation of the students will be based on the written examination at the end of each grade. It carries 75 percent of the total weightage. The types and number questions will be as per the test specification chart developed by the Curriculum Development Centre.
