LCD (liquid-crystal display) projectors have been in use for several years now. They play a critical role in transmitting graphics and videos on a screen or any level surface. Although they’ve been quite widespread in offices, it has not been the case with schools.
Today, most schools across the US have jumped on the bandwagon. Overhead projectors and other conventional methods like films are slowly being phased out. Thanks to the dropping technology charges, even schools on a budget can afford an LCD projector.
With the advent of LCD projectors, chalkboards are losing their importance every day. After all, these devices project crisp, close-up photos and videos. All a lecturer needs is to prepare PowerPoint slides and relevant videos; fantastic, right?
Various LCD Uses for Schools
Teachers can use LCD projectors in various ways to achieve different results. There are many reasons why gadgets have become so popular across all learning institutions. Below are some ways that teachers use LCD projectors in school today.
Speech alone can be boring in a class setup. Whether you’re dealing with slow or fast learners, everyone needs more than mere words for proper comprehension. When explaining in detail, a lecturer can elucidate a point by using a marker pen.
Just try to visualize a teacher highlighting special features on the whiteboard. Students will find it interesting, thus grasp more. Also, students can prepare slides and present them during a lecture. From such presentations, the lecturer would sufficiently gauge the students’ understanding.
For tabletop demonstrations
Explaining crucial details to a large audience is always challenging. Rarely do students understand, especially in large lecture halls. Like, an anthropology professor may find it hard explaining the skull structure to a crowd of students.
Tabletop demos are best done using an LCD projector connected to a webcam for enhanced clarity. It makes work easier for the lecturer. The students also acquire knowledge faster. In such a class, you will find students asking questions, a sign they are at par with the lecturer.
Easy attendance of webcasts and webinars
With COVID-19 affecting how people do things, schools were not left behind either. Staff members couldn’t attend conferences and training following the social-distancing restrictions. Those with LCD projectors only need to link them to network-connected desktops.
The computer will then display live-streamed training plenaries, thus eliciting so much enthusiasm. By doing so, teachers learn safely and save on travel expenses. Schools without a good LCD projector are left behind because they cannot participate in such interactive forums.
Advantages of LCD Projector in Teaching
You cannot overemphasize the need for LCD projectors in schools today. As seen, both tutors and students are quickly embracing them for better learning. Below are the advantages and benefits that schools reap from LCD projectors.
1. Flexible teaching
Conventional chalkboards are very limiting when teaching. A teacher may be talking about things that students have never seen before. An attempt to create the right image in their minds can be very hard.
However, with an LCD projector, students can listen to global experts for better comprehension. Lecturers can also present web content for the students to read and listen to. It becomes much better than asking students to visit the internet individually.
2. Better time management
Before embracing projectors, teachers would spend a lot of time writing notes on the boards. Sometimes they would erase them before some students were done writing. Projectors are the easiest to work with because each student can view everything clearly.
Again, even if a teacher removes an image, they can display it again when required. Time taken to write for both students and teachers is a lot. After displaying content, a teacher can even allow the students some time to discuss what they see until each of them understands.
Unlike the bulky flat screens, LCD projectors are set to be accessed by all present students, even in a large lecture hall. Do you know how irritating it is to sit behind a tall person in a movie house? This can never be the case with a school using an LCD projector.
The lecturer only needs to set up the projector well for each student to enjoy a clear view. But, the setting determines the results you will get. To acquire a perfect view, consider these three critical aspects;
4. Better student presentations
Presenting a project or proposal has often been challenging for students. Trying to explain your point to the panel is never easy. Today, you can use an LCD projector to display your well-prepared points for all to see. Projectors also make the students more creative when preparing content.
Showcasing through a projector is the best way to sell an idea for the first time. Don’t get surprised at seeing lecturers nodding as you expound on your highly organized PowerPoint slides. It boosts students’ confidence and ensures that both parties are reading from the same page.
5. Clearer, larger display
One major advantage of LCD projectors is their ability to project huge and clear content. If there are too many students in a hall, the teacher can double-stack LCD projectors. It helps achieve unmatched clarity.
If the surface is large enough, certainly the experience will be better. If you are wondering how it works, it’s very simple. Maybe you have 2 LCD projectors, each having say 10,000 lumens.
When you light both and put them next to each other, combined they produce 20,000 lumens. That’s a considerable amount of light added. It’s enough to improve crispness by up to about 70 per cent.
6. Fun learning
LCD projectors allow teachers to use videos, making learning very interactive. Students enjoy much more than listening and copying notes. Again, watching and reading alongside the teacher ensures better understanding.
Where students do not seem to understand, a teacher can connect their computer to YouTube. Watching relevant videos together can be very eye-opening. Also, the teacher can pause the video and ask questions or allow students to ask. LCD projectors could not give a better experience than this.
Busting Myths and Conceptions About LCD Projectors
LCD displays have come a long way. They have also improved considerably over the years. Unfortunately, there are still a lot of lies about LCD projectors out there. We’re here to debunk some myths you may have believed for the longest time.
1. Projectors are too pricey to afford
Most schools lack projectors because they have been made to believe they are too expensive. This is such a pure lie. Something like a 3-LCD Business Projector – 3500 Ansi Outdoor Projector is pretty much affordable. With commitment, any school could buy this product within the shortest time. Some are actually cheaper than the TVs mounted in some homes.
2. LCD projectors are not effective for learning because you require a completely dark room
It may have been the case in the past, but not anymore. Today’s LCD projectors are quite bright and can display in a fairly lit room. Today, all you need is to set it up in an ideal location. There shouldn’t be sunlight hitting the screen directly.
3. The best projectors are those with a higher lumen
Don’t simply buy a projector expensively because of more lumens, and forget about other qualities. You should first know the size of the lecture hall and the projected throw distance. This should help you calculate the actual lumens you need.
4. You can use a projector screen instead of a white wall
While a white wall will still allow your students to read, the results will be substandard. Since this is a school setting, it would only be wise to invest in the best projector screen. You will be surprised at how affordable it is. Most importantly, it minimizes contrast and color absorbance significantly.
5. A projector’s brightness depends on the brand
Buying an expensive LCD projector from a reputable brand doesn’t guarantee quality image projection. Again, not that cheap LCDs are the best for classrooms. Usually, image resolution is determined by three things. You have to rhyme contrast with brightness and lighting. The ambiance of the environment also matters a great deal.
