What is Web 2.0. ?
Check this.
Some examples.
Prezi
This software is basically for presenting ideas. Prezi’s unique features are that you can make your slides zoom in and out, size, rotate, and edit. Also, you can navigate through information by using Prezi. Prezi can also be useful for corroboration work to create presentation slides by sharing with your members. Moreover, Prezi allows you to import files that you have created on powerpoint, and produce new advanced slides based on the original files. You can put YouTube videos, images, and pdf files as well. Those features would be great useful for both of teachers and students to present their ideas and knowledge to audiences in class. Presentations using Prezi would enhance class activities by attracting audiences’ interesting, encouraging them to learn from the slides, and improving visual learning in class.
Audacity
This is a free audio editor. One of unique features is that users can convert recorded data on Audacity to mp3. Considering this point, for education, this software would be helpful for language learners. Teachers can record their speech with correct pronunciation and accent, and students can listen to the records on their portable devices or computers wherever they are. Also, students can record their own speech and check/review theirs.
Edmode
I got most interest in this web2.0 application. This is like e-lerning. However, teachers and instructors can connect and communicate more. Students cannot contact a specific student for a private usage. This application focuses on group work. Teachers can create small groups of students for discussion in class as well. Typically, teachers create a community for one class through Edmode. Teachers post learning activities or comments in basically five ways; Assignment, Alert, Poll, Note, and Quiz. For Assignment, teachers post assignments and files, and set due days; students can submit their assignments through the post. The students can check their results through the application from wherever and whenever they want. For Alert, teachers can remind students of important information. For Poll, teachers post their own questioners; students click their ideas/thoughts/answers. This feature would be helpful to hear students’ voices and feedback to class contents. Also, teachers can post five types of quizzes; true-false, multiple, short answer, fill in the blank, and matching.
These multiple choices, for teachers to create tests on Edmode, would help them to measure students’ achievements. I hope the application will add an information management system as well, so that teachers and students can manage and check learning achievement.
