Correct Answer - Option 4 : all of these
Assessment is integral to the teaching-learning process which helps in facilitating student learning and improving instruction. It is a process of collecting relevant information on student learning. Self-assessment occurs when students evaluate their own work and make a judgment about its quality. Techniques of self-assessment in mathematics learning:
-
Inquiry: After the learner completes a task or develops a model he/she has to minutely scrutinize the outcome after each step followed to complete the task and the final outcome against the expected outcomes.
-
Comparison: The learner then compares his/her own performance (in classwork, home assignments, project work, participation in the teaching-learning process etc.) with those of other learners in the class.
-
Self-analysis: The learner analyzes his own response/result/solution in terms of the steps, formula, principle and techniques followed to solve the problems with his own answer. In course of such analysis, he/she tries to detect omissions, repetitions, mistakes etc in his/her performance.
Hence, all the above techniques are of self-assessment.
