For some online students, learning can be a lonely experience. Instead of professors, they see screens and type. their classmates are out of the picture entirely. But new technologies are allowing professors to change this. One person on the forefront is Greg Moller, a University of Idaho associate professor in environmental toxicology. Learning on an iPod Right now, UI professors are working new technologies into their classes’ online elements to increase interactivity. One up-and-coming feature is podcasting. Moller currently integrates podcasting into his online Introduction to Food Toxicology and Principles of Environmental Toxicology classes. He said a memory of sitting under a tree and reading a book of poetry as a student inspired him to make online learning more mobile. His course Web sites offer audio and video iPod-ready lectures. Registered students can access the lectures live, and anyone can stream them for free after they’re posted. It’s also been important to use this technology to create a warmer atmosphere for online students, Moller said. Many video lectures seem like “dancing peanut videos,” he said, in which the professor does not engage with students that may be watching. To avoid this, Moller has been careful to include his face and clear expressions into the video. “Because this virtual classroom’s a cold environment … the ability for me to put my face there is a warming element,” he said. “We’ve put a lot of emphasis on human factors.” Moller said one of the greatest benefits of online classes is allowing students from all over the globe and many educational levels to take the same course and interact. Global online classes present the problem of “asynchronicity,” since not everyone is in the same time zone, Moller said. However, allowing students to access lectures both live and via the podcasts, which are available 24/7, is a step in solving this. About 50 percent of the students in his online courses are off-campus, Moller estimated. They are from all over Idaho, 12 states in the United States and countries including Australia, Germany and Thailand. A woman in the military in Kuwait took the environmental toxicology class because she was studying how to deal with depleted uranium from shells. A doctor from rural Mexico took the class to learn more about water quality measures. Another distance learner is Carole Asbury, an environmental technician managing waste and disposal for Potlatch Corporation in Lewiston. She has taken the first four classes of her master’s degree online through UI. Last semester, she took Moller’s environmental toxicology class and said it was the best online course she’s taken. Other classes were just slideshows with accompanying audio, Asbury said. Both the video format and an emphasis on discussing class materials with other students made Moller’s class more effective. New tools for demonstration Podcasting is just one of the technologies available to professors who want to take their online courses to the next level. Teachers can also hire CTI to develop Web sites and elements for them. For example, CTI built a model cell for a biology class Web site, along with interactive elements like timelines, quizzes and crossword puzzles to help students study. For an environmental hydrology class, CTI developed a Flash video tutorial in wading rod use. Normally, students in this class would take a field trip to learn to use a wading rod, Schlater said, but since they are in an online class, another form of demonstration is necessary. Other professors who teach online classes also face the challenge of how to demonstrate material to students. Thomas uses a program called Centra to conduct live, online sessions with his students. Centra’s features include online chat, virtual whiteboard and application sharing — if Thomas has a program open on his computer, his students can access through their browsers, even if it’s not installed on their computers. “I find out what kind of problems they are getting stuck on, and that prepares us for our next synchronous chat,” he said. So far, the system has worked wonderfully, he said. The online class of the future A technology not yet used at UI, but growing in popularity across the country, is Second Life. Second Life is an online virtual world in which real people interact through 3-D avatars. “Residents” in Second Life, as players are known, can buy and sell products and services, form clubs and even take online classes. Greg Moller plans to put his classes in Second Life by next fall. He has written two grants to buy a “private island” within Second Life, which he plans to name “Idahonia.” Idahonia will provide a secure place both for Moller’s classes and for other UI professors and students interested in using Second Life for education. “(Second Life) is a tremendously powerful social interaction tool,” he said. Schlater said such an online environment may help students feel more comfortable speaking up in the classroom. Second Life also has the potential for simulation — for example, UI instructors could build a contaminated stream or chemical spill within Second Life for their students to study, Schlater said. New technologies such as Second Life may sound foreign to professors used to traditional teaching. But the growth of computer classrooms shows that new technologies can become part of daily life, Schlater said. Though Schlater and Moller agreed that online classes will never replace physical classrooms, the improving technologies are making online learning a better adjunct to on-campus classes.
