It provides a link to real-life developments. It can be a catalyst that changes schools. Technology changes the instructional role of the teacher and the educational environment of the school. Much responsibility for learning is now in the hands of the students. They are transformed into masters of their own education. For this, they must possess the cognitive strategies inherent in Information Literacy." Barton, Holly Information Literacy: Learning How to Learn,

Answer on the word processing document in a contrasting color (not yellow) or font (avoid Symbol, blackmore, brodfont dear or other ornate artistic fonts). Save frequently as you work. Enter your name and the date in a header. Submit the assignment via a class dropbox or an email attachment. Bad things happen. Save a copy of your document in your computer. Perhaps you have the resources to record verbal answers. If you do, be sure to first read / record the question. Then record the answer immediately after it. Proof your responses.
