Webquests

The first webquest I opened was the Freedom Fighter or Terrorist webquest. This was a very interesting way of depicting information. Once again this is a resource that has many possibilities. One of the major advantages is the ability for students to access this outside of conventional class hours. The information could be rendered in such a way to appeal to many types of learners, particularly the visual and the introvert learners.
The use of webcasts would change the face of the classroom greatly. A classroom wouldn't necessarily become a quiet place, more likely a hub of busy discussion and chatter. The teacher would become a moderator, a person who assists when students become stuck or unsure. A person to answer questions and steer students in the right direction if they get lost. This approach would be a large turn away from chalk and talk but at the same time, hold similar attributes. The large difference is the medium the students are engaging in. The computer, the webcast is a medium that appeals to today's students, as opposed to the board and chalk of yesteryear.
A large implication I foresee for the webcast is time. It would take a large amount of initial time to create the webcast which may only cover a week or two's worth of curriculum. Many hours would be taken to complete the full webcast document. The second issue is availability of subject matter. For a plan to completely change over to webcasts would required a great amount of resources that could be accessed and manipulated quickly and easily. They would also need to be able to access the resources at times when the computer system might fail.
These implications don't make it impossible to suggest, nor should it make the idea obsolete, instead it just means there needs to be a contingency plan. Overall, the webcast would need to cover almost an entire set of subject matter to be a viable alternative.
