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 evaluation

Internal assessment includes classroom participation, terminal examinations, and project work/practical work (computer works and lab work) and presentation. The scores of evaluation will be used for providing feedback and to improve their learning. Individual and group works are assigned as projects.

The basis of internal assessment is as follows:

Classroom participation	Marks from terminal examinations	project work/practical work	Total
3	6	16	25

(i) Classroom participation

The mark for classroom participation is 3 which is given on the basis of attendance and participation of students in activities in each grade.

(ii) Marks from trimester examinations

Marks from each trimester examination will be converted into full marks 3 and calculated total marks of two trimesters in each grade.

(iii) Project work/practical work

Each Student should do at least one project work/practical work from each of seven content areas and also be required to give a 15 minutes presentation for each project work and practical work in classroom. These seven project works/practical works will be documented in a file and will be submitted at the time of practical evaluation. Out of seven projects/practical works from each area any one project work/practical work should be presented at the time of practical evaluation by student.

b. Final/External Examination

Final/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.
