Leading a Discussion
- Group given a black box activity
- Group selects a main inquiry objective, (a) observation/inference; (b) hypothesis & theory; (c) sharing, discussion, debate, communication
- Group discusses how to approach running the activity and leading a discussion that emphasizes the main focus
- One person in the group runs the activity and discussion, teammates observe and prepare a follow up critique to lead a whole group discussion
- Group members may pass suggestions to leader in the form of notes or side comment
- The discussion leader is expected to employ discourse strategies from section A below.
Classroom Discourse Practices
AEngaging student reasoning out loud
- Prompting participation (something add? New idea?)
- Asking student to restate someone else’s idea
- Asking student to apply reasoning to another idea (do you agree? Why?)
BBuilding a case or argument
- Wait Time I (after teacher talk) and II (after student talk) (stimulates more discussion)
- Teacher highlights a student idea – for some purpose
- Teacher restates student idea (to give emphasis or to engage student reasoning)
- Teacher summarizes or combines student ideas (building a case or argument or position)
Wooden boxes with unknown obstructions
- Sources of data: sound; feel; orientation
- Observations, discussion, agreement/disagreement
- Hypothesis, a limited claim intended for building a theory or explanation – hypothesis about where just one obstruction is located
- Theory, the complete explanation – draw the inside of box
- Theory testing – not so easy, you cannot match this box; you can put material in an empty canister and see if it sound similar
- Always room to improve theory – draw a different or more accurate diagram
- Collaboration, debate, communication – groups can share data, theory, ideas and see if they agree
- The box can remain closed – in science you never have a “God’s eye view”

Film canisters with unknown materials
- Sources of data: sound; feel; weight; magnetism
- Observations, discussion, agreement/disagreement
- Hypothesis, a limited claim intended for building a theory or explanation – hypothesis about individual materials in the canister
- Theory, the complete explanation – list the materials or types of materials inside
- Theory testing – make up another canister that sounds, feels, weighs the same
- Always room to improve theory – make up a different canister and see if it matches better
- Collaboration, debate, communication – groups can share data, theory, ideas and see if they agree
- The canister can remain closed – in science you never have a “God’s eye view”
