Clickers in math class Kim Roth Juniata College

2
Set up your clicker When you turn on your clicker, it should scan for classes and find ROTHNEXT. Hit enter (the green key) to join the class.

3
Have you heard of clickers before? a) All yes b) Some yes c) All no

4
Have you used clickers before a)All yes b)Some yes c)All no

Why use clickers? Instant feedback from all Anonymity encourages guessing Facilitates Peer Instruction Increases retention of material Takes attendance and tracks participation Especially good for warmup questions

7
Picking a clicker type School preference IR vs. Radio Receiver hardware Types of possible answers Interface with Power Point Question availability from publisher Classroom set vs. student purchase

8
Things to keep in mind Many ways to count towards grade or not Forgotten clickers Integrating in lecture takes time Not all systems interface well with Power Point Hardware setup can be long

ConcepTest Section 1.3 Question 7 For Problems 7-13, let f and g have values given in the table. f (g(1)) =

10
ConcepTest Section 1.7 Question 6 True or False: the function is continuous on the given interval. The cost of a first class stamp over the past 100 years.

ConcepTest Section 2.1 Question 2 For Problems 1-3, assume your car has a broken speedometer. In order to find my velocity at the instant I hit a speed trap, I need 1) The total distance of the trip 2) The highway mile markers 3) The time spent traveling 4) How many stops I made during the trip 5) A friend with a stop watch 6) A working odometer 7) None of the above

12
ConcepTest Section 2.4 Question 1 For Problems 1-3, the function C(r) is the total cost of paying off a car loan borrowed at an interest rate of r% per year. a)Year/$ b)$/Year c) $/(%/Year) d) (%/Year)/$

13
Section 6.4 Question 2 If the graph of f is given in Figure 6.8, then which of (a)-(d) is the graph of for 0 ≤ x ≤ 4?
