Measurement - objective observation
"The process of assigning numbers that estimate the degree to which a person or object possesses some specified property, attribute, or characteristic."
- Estimating a degree - "Let's see how you measure-up."
- IQ Test- have to know the scale to interpret the data.
- Assumption- if they get something right, they would also get the easier items right.
- NOIR- Nominal (Categorical, more of a label/description), Ordinal (Ranking), I.., Ratio Data
- Measurement is NOT classification (no nominal data). So for hair, measurement is the "Level 12," not brown, blond, or red.
- Objects have characteristics, but it is the properties of the object are what are measured. So we don't measure Sara, we measure how tall Sara is.
- Sometimes intelligence is measured, some who measure
- Measurement Process assumes that the property being measured exists in varying degrees or amounts. (issues of state or trait) For example, happiness a STATE. Our fluxuation of happiness is varied, by degree, but dependent on things. TRAITS are more PERMANENT.
- Measure vs. Categorize
- Measurement procedures are often indirect
- Measurement is a human activity
- Measurement ALWAYS contains some error.
- http://www.akdn.org/india_environmental.asp - Women in India not attending schools b/c of lack of private bathrooms
- Quote by Joseph Smith- all things are Spirit but vary by degrees. The Lord measures us: sin, trust in Him, knowledge... Maybe there is more to measurement that could even help me better understand the Atonement.
- Compare
"Spencer is 6'2". Aaron is 5'2"." -- People can understand about how tall Spencer is, and they can know that Aaron is shorter than Spencer. - Communicate
"Spencer is 6'2"." -- People can understand about how tall Spencer is.
Assessment - Making a judgment regarding a person's outcome
"A systematic process of gathering measurement data and turning it into usable information for a specific purpose."
- What should a 3rd-grade student learn? At what level should they perform? (This would require evaluation component of Assessment)
- Assessment is missing a component of considering the goodness of data. It can't really determine whether that performance was good or bad.
- Assessment involves measurement.
- Tests are a particular type of assessment.
- A comprehensive assessment involves a set of planned measurements designed to provide evidence or information about a specific person or thing.
- Assessment is as factual and as objective as it can be.
Evaluation - More thorough investigation of something
"The process of making a value judgment about the person or object based on some set of assessment data."
- Involves judgment of merit and worth.
- By nature somewhat subjective.
- Usually based on a set of criteria (what we value).
- For consistency, evaluation criteria should be clearly defined and generally agreed upon. (We try for that, at least.)
- In graduate school, what should an A represent? Some degree of excellence? No truly shared view of what these really are.
- The Lord evaluates us and takes into consideration opportunity and circumstance.
