As technology grows, many university instructors are finding ways to guide online learning platforms into their classrooms. Programs such as Blackboard, WebCT and Moodle allow teachers to post reading assignments, PowerPoint presentations, lecture notes and quizzes for students to complete outside of class. While posting lessons online can be friendly to students' communication styles and easily accessible, they also cause disadvantages.
One disadvantage is that it may encourage students to depend on technology in the classroom. Instead of physical textbooks, many now bring cellphones to access materials during class discussions. While electronic devices can be valuable learning tools, they also can lead to distractions from learning, such as social networking and online games. It is extremely difficult for students being exposed to multiple electronic tasks to focus or remember key information.
A second disadvantage is that online lessons open up potential for cheating. Many instructors require students to complete quizzes, post within discussion groups or submit major assignments online. As a result, there are some students having someone else complete their assignments. A contributing factor is that online assignments are best suitable for those self-motivated, self-directed students. Students who struggle with organization and completing assignments may find it easy to cheat online.
In spite of these disadvantages, educators can take steps to make sure students use online lessons responsibly. If instructors are uncomfortable with electronic devices in the classroom, they can require students to print out assignments and readings to reference during sessions. To prevent cheating, teachers can use online assignments as a supplement to traditional in-class work, or create open-ended assignments rather than using assignments like multiple-choice quizzes that have only one right answer. Being familiar with what the platform looks like from a student perspective also can help instructors avoid potential pitfalls.
