Projectors are one of the coolest inventions. Movie theaters exist today because of cinema projectors. Projectors are not only used in theaters. They are widely used by large organizations and small enterprises to hone the skills of their employees, explain the projects/processes, etc. Despite being useful, educational Institutes have historically been slow in adopting projectors. If you visit 10 schools in the neighborhood, only a couple of them would have projectors. Why this is so? Well, people managing or working at educational institutes such as schools are in two frames of mind due to a lack of understanding of projectors or because of the school’s budget. For the awareness of such people, we’ve shared the advantages and disadvantages of projectors in the classroom in the below paragraphs:
Advantages of projectors in classrooms
Easy to explain
Most teachers carry a smartphone. Teachers find creative ways to teach students. While using the phone, if the teacher finds a good slideshow or an educational video, he/she can use the projector to share the same with students. The Internet has billions of documents and millions of educational videos. If teachers find something worth sharing, they won’t hesitate to do so. The projector is one of the best teaching equipment.
Observation and notes
Teachers write on blackboards. While writing, they may not know what’s going on at their backs. There’s no class in the school without mischievous students. The mischievous students won’t let other students concentrate. If teachers use a projector in the classroom, the teacher’s eyes will be on students. Another great reason to use a projector for teaching is that teachers can also save time by using the projector to display the notes instead of reading the notes loudly or writing them on the blackboard.
Projectors are available for a price starting at $150. Although you can purchase a television for $150, the screen of the TV will be 32 to 43-inches only. If the class has 100 students, the students seated at the backside won’t be able to read the content displayed on the television. Projectors can create large projections of good quality even if they’re cheap. They support SD, HD, and Full HD resolutions. Cheap ones will support HD or SD projectors. Expensive ones may support FHD, 2K, or 4K projections.
Good use of the computer
If the classroom has a computer, the computer can be used as a television and it can be used to display presentations too. However, the screen of the computer’s monitor can be a problem if the class has many students i.e. 30 or more. It will be a waste of time if teachers show presentations to a group of students at a time. The projectors can solve this problem.
Is there a disadvantage?
The only disadvantage of using projectors is that it can take some time to set up the projector and projection on the surface or screen. If the projection quality isn’t good, you’ll have to change the resolution. If you connect a flash drive to the projector, you’ll have to select the file manually if the projector doesn’t do so. Similarly, if you connect the projector to a PC/laptop with an HDMI cable, you’ll have to configure the PC/laptop to work with the projector. If you’re using an older version of the Windows OS, you may have to install driver software for the projector. If you use Linux, you might have to install packages.
If you’re working for a school and you’re wondering whether you should get a projector for the school or not, we hope that you’ve learned the importance of projectors.
