‘[Project based learners] demonstrate a real grasp (learning, understanding, and application) of the material under study and illustrate the wide potential for learning and information gathering provided by the web.”
As a new teaching approach, project based learning has encountered skepticism, because it bears little resemblance to current practices or methods teachers had learned and experienced as students themselves.
(Lam, Cheng & Ma, 2008)
As teachers we are suppose to be constantly learning. This new approach to teaching is another thing teachers will have to learn in order to produce the most successful students.
Scaffolding is needed for success. This means that teachers will need to put in a lot of time, as well as much support and monitoring.
Yes, successfully implicating a web-based project will take a lot of time at first, but the whole idea of scaffolding is that it is temporary. As the students gain skills, the scaffolds are removed, creating a more teacher-facilitated approach.
