LEARNING GOALS
- B. CONCEPT ACQUISITION
- Techniques for validating instruments:
- a. Interactive exploration: Testing an instrument by changing the thing it is measuring in ways you know through other means, and seeing if the instrument recognizes the changes appropriately (e.g. does driving increase a car's odometer; see how singing higher and lower notes affects a sound spectrograph; sprayable electrons in Hacking reading).
- b. Comparison of multiple instruments (e.g. thermometers)
- c. Comparison to direct observation (e.g. naked sight compared to sight with a magnifying glass)
- C. CONCEPT APPLICATION
- Identify when and how interactive exploration, comparison of multiple instruments, and comparison to direct observation can be used to validate instruments.
- Identify cases in which instrumentation is needed to solve problems (e.g. entities/events are too slow, too fast, too small — that is, those for which we cannot rely on our everyday senses and cognitive capacities), especially in policy contexts.
- Explain how our ability to use the techniques for validating an instrument above can lead to more/less confidence in a given measurement.
