The active use of computers during class makes the teaching process student-oriented instead of teacher-centered. Computers can be used in place of a teacher when the students in a class have a large variability in skill level. In this situation, the student can move at a pace suitable for her, not falling behind or feeling bored, which may happen during a lecture. Moreover, the use of a computer requires literacy.
The Internet plays two important roles in technological classrooms. The first role is a means of communication between students and the teacher. Some teachers set up online discussion forums for their class, which allows students and the instructor to discuss course content freely and at any time. Second, the Internet can be a channel for the dissemination of class material and information. Many courses have established a class website where students can find homework, quizzes and lecture notes. The use of the Internet allows a teacher to avoid having to spend class time on menial tasks.
Microphones are now commonly used in many university classrooms. The microphone allows a teacher to project her voice in manner that allows all students in the classroom to hear clearly. In addition, microphones have the advantage of allowing a teacher to avoid straining her voice. Today, microphone technology has increased to the point of being wireless, allowing instructors ease of movement.
Clickers are devices used by students that can allow them to make choices remotely. Similar to a television's remote control, the clicker lets the user enter information from her seat. This allows for student-teacher interaction in the classroom in a way that is organized. The teacher can immediately display feedback from a clicker, thereby directly hearing student's comments.
