Evaluation systems

Evaluation judges how far objectives are met. It may be formative or summative, norm- or criterion-referenced, and under CBCS it uses credits and grade points.

Elements of evaluation: the evaluation triangle

Objectives, learning experiences and evaluation depend on one another. Evaluation checks the change in behaviour that the objectives aimed at.

Worked example: SGPA under CBCS

Problem

A student earns: Course 1 (4 credits) A+, Course 2 (4 credits) A, Course 3 (3 credits) B+, Course 4 (2 credits) O. On the UGC 10-point scale, find the SGPA.

Working
  1. Grade points: O = 10, A+ = 9, A = 8, B+ = 7.
  2. Credit points = credits × grade point: 4 × 9 = 36, 4 × 8 = 32, 3 × 7 = 21, 2 × 10 = 20.
  3. Total credit points = 36 + 32 + 21 + 20 = 109.
  4. Total credits = 4 + 4 + 3 + 2 = 13.
  5. SGPA = 109 ÷ 13 = 8.38.
Answer

SGPA = 8.38. Shortcut: SGPA is just a credit-weighted average of grade points, so it must lie between the lowest and highest grade point.

CBCS, computer-based testing and innovations

  • CBCS course types: core, elective (discipline-specific and generic), ability enhancement and skill enhancement courses.
  • One credit = one hour of lecture or tutorial, or two hours of practical, per week for a semester.
  • UGC 10-point grades: O 10, A+ 9, A 8, B+ 7, B 6, C 5, P 4, F 0. CGPA is the credit-weighted average of all SGPAs.
  • Qualities of a good test: validity (most important), reliability, objectivity, usability, discrimination.
  • Computer-based testing: on-screen items, shuffled order, quick scoring; a computer-adaptive test changes difficulty with each answer.
  • Innovations: grading, semester system, continuous internal assessment, open-book exams, question banks, rubrics, e-portfolios, peer and self-assessment, online proctoring.
How NET asks this

NET asks you to match evaluation types to their purpose, to spot formative vs summative in a scenario, and sometimes to compute or read SGPA/CGPA under CBCS.

Exam angle

Typical MCQ: “A teacher gives weekly quizzes to give feedback and adjust teaching. What type of evaluation is this?” Formative evaluation: done during instruction to improve learning, not to certify it.

Typical MCQ: “What does a criterion-referenced test compare a learner with?” A fixed standard of mastery, not other learners' performance (that is norm-referenced).

Remember it

Formative forms learning (during), summative sums up (at the end). Norm = neighbours, criterion = cut-off.
