Numbered Heads Instructions
1. Form into the designated groups
2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.
3. Hand the paper to the instructor. It will be used for assessment and graded.
4. Begin reviewing/ learning the listed concepts. Make up sample questions related to the concept. Try to imagine what question the teacher will ask. Time is limited; so don’t waste it!
5. Once you understand the concepts yourself locate the group members who do not understand by assessing them. Do not ask yes or no assessment questions.
Good Assessment. “Sam, could you show me how to do number three on the list?”
Poor Assessment. “Do you guys all know it?”
Now teach them how to answer the questions you have formulated.
Now teach them how to answer the questions you have formulated.
6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a calculator. After they leave begin studying the next set of concepts for the next round.
7. After a short amount of time the person will then return to the group and their answer will be graded by the teacher and given to the entire group as a communal score.
8. The returning group member may be called again so they should receive extra instruction to help get caught up.
9. The scores are added at the end to determine winners. The top three groups receive extra points on the test.
List of Concepts"
Here are the list of concepts to understand for the Chap 18 test for Monday:
1. Know the difference between the terms open circuit, closed circuit and short circuit.
2. Compare pot. dif. across a bulb and across a battery powering it.
3. compare terminal voltage and electromotive force (EMF)
4. find the equivalent resistance for resistors in series
5. In series how is the current for one resistor related to the total current?
6. In series how is the pot. dif for each resistor related to the total pot. dif.?
7. For resistors in parallel express of total current is related to individual current across each resistor.
8. For parallel express find Total resistance
9. For two equal resistors in parallel, compare the equivalent resistance to that of the individual resistor.
10. Use a complex diagram including individual resistances to get equivalent resistance.
11. Use a verbal description of the complex (series and parallel) organization of resistors to construct a diagram and solve for equivalent resistance.
12. Use a complex diagram to solve form equivalent resistance.
13. Use a verbal description of a the complex (series and parallel) organization of resistors including pot. dif. to solve for current and or voltage one one of the resistors.
