- Assessment is an ongoing process which involves the systematic collection, analysis, and integration of information (Hoy & Gregg, 1994).
- Educators do not assess people. Instead, we evaluate their abstract psychological attributes/traits/constructs. e.g. linguistic ability, logical thinking, leadership ...etc.
What is the difference between assessment and measurement?
- Measurement of the psychological attributes occurs when a quantitative value is assigned to the behavioral sample collected by using a test (Crocker & Algina, 1986).
- Assessment could use qualitative or/and quantitative data, and could be formal (e.g. test) or informal (e.g. observation) (Hoy & Gregg, 1994).
How do we use the information resulted from assessment?
- Feedback to improve instruction
- Monitoring progress/Diagnosis
- Communications to parents
- Sociology--social stratification
- The more frequently evaluations take place, the more students generally achieve
- (Crooks, 1988, Kulik & Kulik, 1988, Peckam & Roe, 1977)
Paradigms of Assessments
- Summative vs. Formative
- "How did you do?" (e.g. UK)
- "How are you doing?" (e.g. US)
- Norm-referenced vs. Criterion referenced
- Mental abilities were distributed as a "normal curve"--Galton
- A "normal curve" is a result of no/poor instruction. With intervention the curve should be positively skewed (Smith & Ragan, 1993).
- Fragmented vs. holistic (Camboure & Turbill,1994)
