EDUCATIONAL TECHNOLOGY 2: Lesson 11: The Computer as the Teacher’s Tool

Constructivism was introduced by Jean Piaget (1981) and Bruner (1990). They gave stress to knowledge discovery of new meaning/concepts/principles in the learning process. Various strategies have been suggested to foster knowledge discovery, among these, is making students engaged in gathering unorganized information from which they can induce ideas and principles. Students are also asked to apply discovered knowledge to new situations, a process for making their knowledge applicable to real life situations.

While knowledge is constructed by the individual learner in constructivism, knowledge can also be socially constructed. Social Constructivism is the effort to show that the construction of knowledge is governed by social, historical and cultural contexts. In effect, this is to say that the learner who interprets knowledge has a predetermined point of view according to the social perspectives of the community or society he lives in.
The psychologist Vygotsky stressed that learning is affected by social influences. He suggested the interactive process in learning. A more capable adult (teacher or parent) can aid or complement what the learner sees in a given tasks or project. In addition, John Dewey sees language as medium for social coordination and adaptation. For Dewey, human learning is really human languaging that occurs when students socially share, build and agree upon meanings and knowledge.

The computer can provide vast amounts of information in various forms, such as text, graphics, sound, and video. Even multimedia encyclopedias are today available on the internet.

The computer has been used in communication as evident by social networking sites as to Facebook, twitter and Friendster. We can even chat/talk friends and families anywhere in the globe through yahoo messenger or the one in Facebook or view them through the webcam. We can send messages and information through the internet in just seconds or minutes.

The computer itself can be used for manipulating information, visualizing one’s understanding, and building new knowledge. The Microsoft Word computer program itself is desktop publishing software that allows users to organize and present their ideas in attractive formats.

Students can use constructive tools to work cooperatively and construct a shared understanding of new knowledge. One way of co-construction is the use of the electronic whiteboard where students may post notices to a shared document/whiteboard. Students may also co-edit the same document from their homes.

By means of virtual reality (RS) extension systems, the computer can create 3-D images on display to give the user the feeling that are situated in a virtual environment. A flight simulation program is an example of a situating tool which places the user in simulated flying environment.
