Q: How will you ensure that students retrieve the information they need from the Internet in the allotted class time?
The first step I think would to do a test run searching for the information while preparing for the lesson. Then, assuming it will take the students a little longer than the teacher, estimate the time needed and divide by the class periods length. Like the teacher in the video, I would also constantly walk around the class/lab to make sure that students were on task and gage the amount and quality of information they are finding.
I would also recommend leaving the last five minutes of class for students to print any material that they need, or save anything to their account.
Q: How will you prepare for an activity that uses the Internet?
Preparation would include booking adequate time in the computer lab, as well as doing a test run of the lesson to gage its effectiveness.
