The big dilemma of the day was whether I should have the students hunt for the data themselves or should I just supply it for them. With the use of Excel, students had to analyze a fairly large amount of data. Sometimes, getting that data into Excel can be a headache. There inlies the dilemma.
I think that giving them the data does not allow for the use of certain Habits of Mind that are absolutely necessary for properly using Excel. These Habits of Mind include:
- persistance
- thinking flexibly
- striving for accuracy and precision
- questioning and posing problems
After talking with the stats teacher, I have decided to have the students hunt for the data themselves. Although this is not a standard, this soft skill is extremely important.
