Many teachers find chalkboards to be almost a thing of the past with the advent of projectors in the classroom. Rather than writing notes across a board, teachers can make use of PowerPoint presentations, images and even film as teaching tools through the use of projectors. Consequently, teachers and students alike find projectors to be useful classroom devices.
Easier Note Taking
Projectors enable teachers to create bulleted PowerPoint presentations or other highly organized notes for the class. With the use of projectors in the classroom, students can take better notes with the ability to discern what information the teacher displays is most useful to them. Additionally, students can ask the teacher to repeat a slide if they missed information, or even ask that the teacher to email the presentation for further review.
Greater Teaching Versatility
Projectors release teachers from being bound to chalk and dry-erase boards to present information to their students. With the use of projectors, teachers can now use films, slides, and images to teach students about the world and places they have never seen and can't imagine. Students can listen to lectures given by worldwide experts. Teachers will also find that the Internet is more useful since projectors can display web content to an entire class, rather than each student accessing information on small individual computers. Many projectors also deliver exceptional sound quality, which is advantageous when listening to music or nature films.
Better Use of Class Time
Prior to the use of projectors in the classroom, teachers had to spend time writing notes on the board, as well as erasing information due to limited space. Projectors facilitate the planning process so teachers can decide on lecture content and important points ahead of time instead of making decisions spontaneously. Projectors require a simple click of a button or mouse, thus, freeing valuable class time. By using projectors, teachers can more easily prepare all notes prior to class for easy presentation. Teachers may also find that they spend less time repeating or rewriting information that is now accessible with a simple click.
Better Student Presentations
Students will appreciate the use of projectors as they prepare class projects that they can now create in PowerPoint or other electronic mediums. Consequently, students will find that presentation creation will go faster with each person using their own computer to create their section of the presentation. Presentations on a projector, additionally, reduce the need to make copies of materials to pass out to classmates during presentations that can now be displayed for the entire class to view at once.
