Dimensional Analysis CAT

Procedure

Time: 

Approximately 10 minutes

Materials:

  • Computer with Internet Access

  • Digital Projector connected to the computer

  • Calculator  [A calculator is an indispensable tool that a student should always have at their disposal in a classroom setting]

  • Memory Matrix and Half Sheet Response Form   [Though this form, which is to be cut in half, is not necessary - it serves to help faculty to easily collect and analyze data in a manner that is time efficient.]

Implementation:

This RWLO CAT is to be administered immediately after students have received instruction on metric-metric and English-metric interconversions using dimensional analysis.

Steps:

  • Pass out Memory Matrix and Half Sheet Response Form.

  • While the students are filling out the Memory Matrix portion of the CAT, the instructor can start to gain access to a web site (http://kitco.com/market/), which gives current prices for various precious metals and currency exchange rates.   Scroll down so that both the price of the metal and the currency exchange rates are visible.

  • Select a precious metal, have students record the current bid price in the New York Spot Market (given in $US/oz), select a currency, have students perform a currency/mass interconversion.  This should take no more than 5 minutes.

  •  Have the students turn in the CAT.

  • Analyze the CAT and based on its results, teaching effort refocusing may be necessary.
