Viewing animations in class

• Made chemistry much easier to understand
• Made chemistry slightly easier to understand.
• Didnt change how I learned chemistry
• Made chemistry slightly harder to understand
• Made chemistry much harder to understand

If I had access to chemistry animations online

• I would make them an integral part of my study
  process because theyre very helpful
• I would make them a small part of my study
  process because theyre somewhat helpful
• Im not sure if Ill use them or not
• I probably wouldnt use them much because they
  are not helpful
• I would avoid them like the plague because they
  actually hurt instead of help

I found the virtual helproom

• Very helpful
• Somewhat helpful
• Not helpful at all
• Cant say because Ive never used it

If I had a choice between a traditional
chemistry course (such as this one) and a
high-tech course with 1/4 to 1/2 of the
lectures replaced by interactive web assignments
and animations, I would

• Definitely sign up for the high-tech course
• Probably sign up for the high-tech course
• Not sure
• Probably stick with the traditional course
• Definitely stick with the traditional course

Who cares?!? Its soooo tedious and boring!It
has nothing to do with me.
