Electronic delivery of lectures
Instead of having in-class lectures, electronic delivery of lectures provide more opportunities for students who live in suburban areas or those who are unable to attend lectures due to various personal reasons to participate in real-time lectures. Softwares designed for electronic delivery of lectures have been widely used in different areas because of their ease of use and convenience. As Justin Reich and Thomas Daccord (2008) stated, there are ten ways to enhance lectures with PowerPoint:
1) Include visual evidence in your lectures with images of art, artefacts, and architecture.
2) In discussing authors, include audio and video clips of them reading their work, which can be put directly into PowerPoint.
3) Include charts, graphs, and figures to supply statistical support to an argument.
4) Show a sequence of maps that demonstrate change over time.
5) Compile short examples of student writing to critique or edit.
6) Sum up the essential points or questions of a lecture in an outline slide.
7) Use charts, diagrams, and matrices to help students see relationships among ideas or information.
8) Use portraits or photographs so students can see pictures of the people you discuss.
9) Include cartoons or funny illustrations to inject humour into your presentation.
10) Use slides with titles and subheadings to help listeners follow the argument in longer lectures.
With the advantages stated above, such use of technology has become popular among teachers, professors and presenters. Teachers can upload the PowerPoint presentations on the internet portal and students will be able to download them onto their personal computers for revision.
Effective use of I-Conferences can also enhance the electronic delivery of lectures. As Judy Lever Duffy, Jean B. McDonald and Al P. Mizell (2005) pointed out, for teachers, conferences offer a way to open communication lines and discussions between students and among educators. Teachers can interact with colleagues across the globe to share ideas. And, their own students and students connected to the internet anywhere in the world can join together to work collaboratively. … And because conferences provide asynchronous interaction, differing time zones or constraining classroom time schedules do not interfere. Students can check the messages posted in the conference whenever class time allows.”
With such technology in use, students all around the world will be able to receive the online lectures as long as they have internet access. By using I-Conferences, educators will be able to set up a discussion board and allow students all around the world to participate in the discussion. Thus, students will have more opportunities to exchange ideas and learn from their peers.
The usage of Skype or MSN with visual and audio support will be able to link teachers and students from different parts of the world. This will make it possible to share performance techniques and allow immediate feedback from peers or mentors. Although the outcome may not be as good as in class teaching, it is still considered a good alternative in circumstances described above.
Last but not least, email is another popular tool in teaching accepted by many. As Grabe (2004) mentioned, “email is an internet access system for sending, receiving, and storing messages. It was one of the first internet applications, and it remains the most frequently used.” Teachers and students can use email to communicate with each other and exchange information. Grabe (2004) also stated that, “among the more common email projects are exchanges of correspondence with other students to learn about the collection and integration of data from many different locations, and projects that involve sharing student-generated literature or newsletters.” In addition, virtual space in our email account is able to offer us well- organised and easily accessible storage.
