Day 43: 30 minutes huh? That’s all I get today?

Classes today were only 30 minutes long today.  Students were dismissed at 12:10 because we had Parent-Teacher Conferences from 12:50 until 8:00PM and then again Friday morning from 7:45 to 11:45.  So, what did I do with 30 minutes?

Advanced Physics:

We had finished WB’ing the constant acceleration problems the day before, and the students had been working on some free fall problems.  Well, 30 minutes is not enough time to set-up and discuss WB’s for 4 free fall problems. Instead, the students essentially had work time.  The first order of business was to ask any questions about the free fall practice. Second on the list was to check their answers.  I created a ‘test’ in Schoology that was a Fill in the Blank format.  The students simply entered their values to all the problems, then hit submit.  If their answer turned green, they were correct.  If it turned red, they were incorrect. I gave them unlimited tries.  I liked this for two reasons: (1) it follows the color coding I have been using all year. (2) it allows the students to check their work, without being told how to do the problem.  It really fosters discussion and collaboration as they work to determine the correct answer.  I am becoming convinced that a student could trick him/herself into thinking s/he understands the concepts or problem as s/he reads through my work.

There is one drawback with Schoology and this.  It does not allow a range of answers, so I had to specific how many digits beyond the decimal point to use (some kids used -9.82m/s/s while I used -9.8m/s/s).

General Physics:

We finished discussing the test and then voted on our Magic Mirror pictures.
