Cardboard+Cube

Cardboard Cube

 * The new class duration is 3 hours and 20 minutes. The time was appropriate.
 * Most of the cubes they made had inside dimensions smaller than the required amount.
 * The statistics calculations went well.
 * The understanding of the statistics needed a little more support.
 * Maybe a little movie or a review questionnaire would have helped.
 * The space for answering questions on the handout was too small.
 * We were not too clear on whether the questions should be answered on the handout or on the mininotebook.
 * Maybe a separate sheet with the questions requiring a lengthier answer should be prepared.
 * The questions appear in the handout with the indication that the answers are to be written in this separate sheet.
 * Some of them did not make the mininotebook.
 * When spotted this, we made the student do the mininotebook on the spot.
 * We had a plan for them to turn in a clean version of the handout.
 * However, we decided we wanted to avoid collecting anything at the end.
 * We scrapped that idea.
 * I am not sure they understand that they have to get a 3 ring binder.
 * If they wait they will damage or lose their work and their documents.
 * Downloading podcasts
 * We realized that some of the links we gave them were removed by itunes.
 * They periodically remove podcasts from their links.
 * We took care of the individual issues.
 * Overall, they were successful downloading the assigned podcasts.
 * Some thought that the videopocast was their presentation. We have to remind them that these are two different things.
 * We found a value for the density of bagged sugar (.700) and for the density of piled sugar (.900)
 * We picked .800 as the "true" value
 * 3 students forgot to measure the mass of the cardboard cube and subtract it from the total mass
 * I undercorrected for this in the class results
 * Class results under these conditions: .826±.052 (.826±6%) which contained the "true" value of .800
 * If we had chosen to go the percent error, they would have obtained the value within 6%.
