17. 17 The process Choosing the constructs:
Make an initial list
Buoyancy
Using Evidence
Graphing
Conceptual Complexity
Building Explanations
18. 18 The final set Buoyancy: Why Things Sink and Float (WTSF)
Building Explanations

21. 21 Some additional examples Issues, Evidence, and You (middle school)
Evidence and Tradeoffs
Designing and Conducting Investigations
Understanding Concepts
Communicating Scientific Information
Group Interaction
22. 22 The Evidence and Tradeoffs construct
23. 23 The Designing and Conducting Investigations construct
24. 24 Additional Examples Living by Chemistry (High School)
25. 25 Choose item types/outcome space Multiple choice
Ordered multiple choice
Short answer
Essay
Investigation
Portfolio
Less information
Easier for teachers and students
More information
More time-consuming and expensive
26. 26 Combination of different types Pretest: Multiple choice, Short answer
Reflective Lessons: Short answer, Open-ended
Posttest: Multiple choice, Short answer, Open-ended
27. 27 Choose and Apply Measurement Model In this case, two dimensions:
Buoyancy (WTSF)
Building Explanations
Other possibilities
E.g. near/far transfer items in pre/posttests
28. 28 Why a measurement model? Reliability evidence
Comparability of scores from different tests (e.g. pre/post and embedded)
Graphical summaries of many sorts
Data driven decisions
Summaries of data at many levels
Both normative and criterion based
Calculation of unexpected responses
