CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Reliability means whether the assessment measures consistently. If a student takes the same assessment twice, they should achieve the same result. But also when two lecturers grade the same assessment, they should end up at the same score.

Detailed explanation-2: -To be valid for any purpose, an assessment should represent well the knowledge and skills it in-tends to measure, be used appropriately for intended purposes, and have positive consequences for instruction and for test-takers, guiding better decisions rather than restricting opportunities.

Detailed explanation-3: -How are reliability and validity assessed? Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory.

Detailed explanation-4: -A good assessment should be reliable, valid, and free of bias. First, reliability refers to the consistency of students’ scores; that is, an assessment is reliable when it produces stable and consistent results. Reliability can come in two major forms: (1) stability and (2) alternate form reliability.

Detailed explanation-5: -For an exam or an assessment to be considered reliable, it must exhibit consistent results. Deviations from data patterns and anomalous results or responses could be a sign that specific items on the exam are misleading or unreliable.
