For Day 122, we mainly did some conceptual review to finish getting ready for the COE summative test. I created a series of three clicker questions based on a spring-loaded toy dart gun:
All three questions had the same basic format as the first one:If the spring had been compressed twice as much, the maximum height would be: (A) 1/4 (B) 1/2 (C) the same height (D) twice as high (E) four times as high. After we discussed two more similar problems, I asked the students to ‘quantify’ it by determining the maximum velocity from the values I had given them.
They took the summative test for the unbalanced (N2L) unit.
Then the next day…..
The summative Unit 7 test… broken into two parts, Conceptual and one (power) problem followed by the COE problem the following day. I find it lowers the stress of the students, especially with a bigger test like this one.
We took the post test for the ‘Forces Diagnostic’ which many of you know by a different name. I have yet to analyze the results.
