With the advent of projectors in classrooms chalkboards are almost obsolete for many teachers. Teachers do not have to write notes on a chalkboard. Instead, they can utilize projectors to make PowerPoint presentations, images and even videos to teach using tools. Teachers and students alike find projectors to be effective classroom tools.
Easier Note Taking
Projectors can be used by teachers to make bulleted PowerPoint presentations, as well as other organized notes for the class. By using projection devices in classrooms, students are able to note better notes thanks to the ability to recognize what information the teacher displays is most valuable to them. Students can also ask the teacher to repeat an entire slide if they miss information, or even ask for the teacher to send the presentation for further review.
Higher Teaching Capabilities
The projectors free teachers from having to use dry erase boards and chalkboards for presenting information to their students. Through the use of projectors, teachers can make use of slides, films, and images to instruct students about the world and places they've never visited and can't imagine. The Internet lets students take part in lectures given by experts from all over the world. The Internet is also helpful for teachers since projectors can show the web's content to the entire class, instead of every student having to access it from their personal laptops. Many projectors provide excellent sound qualitythat is advantageous when listening to nature films or music.
Better Use of Class Time
Prior to the advent of projectors in the classroom teachers were required to spend time taking notes on the boards, as well as erasing information due to limited space. Projectors facilitate the planning process to allow teachers to decide on the lecture's content and key points ahead of time instead of making decisions on the fly. Projectors can be controlled with a single click of a button or mouse, thus, freeing valuable class time. Teachers can create notes in class more quickly with the help of projectors. Teachers might also notice less time writing notes or repeating the same information. All they have to do is hit a button and it's accomplished.
Improved Student Presentations
Students will appreciate the use of projectors as they design class projects they can design in PowerPoint or other electronic media. Students will also notice that presentation creation will go quicker with every person using their own laptop computer to create their section of the presentation. A projector makes it possible to display materials for all classes at once, which reduces the need to print copies of the materials.
