Gone are the days when teachers had to use white or blackboards to teach students. Projectors have replaced the whiteboards in the majority of schools.
Teachers today don’t have to write on boards. They can just prepare a PPT presentation, videos, and other content beforehand and display it in classrooms through projectors. This saves time and makes it easy for students to understand what is being taught.
However, the dilemma arises when schools or teachers choose suitable projectors for classroom use. It’s not easy as projectors come in various shapes and sizes. There is no one fit for all.

- How are projectors helpful for both teachers and instructors?
- What features should you look for?
- How to choose the projector?

So, let’s dive in.
Why Should You Have A Projector In Your ClassRoom?
Today’s classrooms are changing rapidly due to the introduction of innovative technology. Technology has made classrooms much more interactive than ever. Imagine all those videos, PPT presentations, and audios available in classrooms today. This was not present in older days. Teachers had only boards to present the information to the school, which was not a productive way to teach.
However, today, teachers can display PowerPoint presentations, photographs, and even movies to engage students in their lessons with projectors.
Below are some advantages of using a projector in a classroom that you should be aware of:
#1. Using Class Time More Effectively
It’s no secret writing on board is time-consuming. Before the invention of projectors, teachers had to go to the classroom daily and write notes on board, erase them, and rewrite the content as the lesson progressed.
These classroom disruptions often resulted in students losing interest in learning or chatting among friends to pass the time. The end result was a waste of time for both teachers and students.
But not anymore. With projectors today, teachers can plan presentations and exercises. The best thing is that these resources can be used several times for multiple groups of students. Teachers can even share their notes with teachers who need help with lessons. ‘
Not only do projectors save teachers time, but they also make students more interested in learning. It’s a win-win situation for both parties.
#2. Efficient Note-Taking
Listening and taking notes at the same time can be difficult for students. You can share notes digitally afterward if you show slides and information via an interactive projector. As your students know that you’ve taken care of notes for the whole lesson, they can focus on listening and only note down information that is relevant to them.
Using a projector, teachers can showcase bulleted PowerPoint presentations or share these slides with students after class is over. If students miss information, they can just go through the shared presentations and understand the topic.
#3. Greater Teaching Adaptability
Teachers are no more limited to chalks and boards. With classroom projectors, instructors can present study material in various forms, like short films, PPT slides, images, and PDFs to teach.
The Internet also plays a key role as instructors can display web content directly to an entire class rather than having students access information on their personal computers, which is a significant distraction. Moreover, the exceptional sound quality of today’s projectors makes learning more fun and memorable.
#4. Interactive Presentations
When students are involved in learning, they can concentrate better on their work. That’s why it’s essential to be sure about how to choose a projector screen. One interactive projector screen can accommodate up to ten students at once, so students can work on group projects and presentations simultaneously.
When students are working together in front of the class are more likely to participate in-class activities. In turn, they become more engaged throughout the lesson.
#5. Increasing Classroom Productivity
Projectors in classrooms that display notes interactively save professors the trouble of writing on the board. As a result, students are also free from being distracted by ’empty silent moments’ and hence, are less inclined to interrupt or converse with other students.
Things To Look at While Choosing The Right Projector For Your Classroom
Purchasing a projector for school is a challenging process. You have to make a checklist for the environment you plan to use, including the size, open space, and light source. You also have to keep an eye on various features available for each projector model and pick the one that matches your needs.
#1. Projection Technology
Most educational projectors come with digital light processing (DLP) or LCD projection technology. However, currently, DLP is used by the majority of educational institutions. This is because the light projection of DLP projectors tends to be robust and suitable for spaces with higher ambient lighting, such as classrooms and conference rooms.
Another advantage that DLP projectors have over other projection technologies is that there is a low motion blur which is an issue with projectors. On the other hand, LCD projectors have the advantage of having higher lamp life than DLP projectors, although motion blur is an issue.
In the end, projection technology will depend on factors such as classroom environment and school budget.
#2. Light Source
Three types of light sources are used in projectors: LEDs, lamps, and lasers.
- LED Projectors: LED models are small and compact, so they can be packed in a pocket or purse. They are also environmentally friendly, making them appropriate for extending classroom resources.
- Lamp-Based Projectors: In general, lamp-based educational projectors have existed the longest and have been the cheapest. Because of this, they can be the most cost-effective solution for low-use applications.
- Laser Projectors: Education projectors with laser light sources may initially cost more but can be more effective in the long run. This is due to their longer lifespans and fewer maintenance requirements.
Resolution refers to the number of pixels displayed on a screen, not the physical display of the projector. Instead, it concerns the quality of the projected image.
The resolution of an image gets determined by the number of dots or pixels displayed. Higher-resolutions result in crisper, more transparent images due to the usage of more pixels.
High resolution is crucial when presenting detailed charts, graphs, and high-definition video. As an example, 1920 x 1200 indicates a high resolution.
Most classroom viewing materials do not require ultra-high resolution. Education projectors with higher resolutions can display better details. Subjects like science, technology, and math classes may be an exception to this rule.
#4. Ambient Lighting
The brightness of a projector is measured in lumens. The more light you want, the higher brightness you will need to deliver sharp, clear images. When shopping for a projector, it’s essential to consider two-lumen specifications: one for color brightness and one for white brightness.
Using a projector with a minimum brightness of 2500 lumens is highly recommended in classrooms or rooms with windows. In the end, you will need to choose projectors based on the light conditions in the school.
#5. Short Throw and Ultra-Short Throw
The projected image’s size depends on the projector’s distance from the screen. This means the farther your projector is, the larger image it can project. But, the projector’s length from the screen varies with different projectors. This is called the throw ratio.
Throw ratio largely depends on the lens. We often classify projectors into regular, short, and ultra-short throws.
- Regular: In most classrooms, regular throw projectors seldom work. This is because they need to be too close to the screen or mounted above the head or behind the students. This creates several challenges, including too small images, shadows, etc.
- Short Throw: Show throw projectors are ideal for classrooms as they reduce the projection distance by more than half. In fact, projectors with high-quality, short-throw lenses produce stunning, big-screen results, even in small spaces.
- Ultra- Short Throw: Ultra short throw adds to the advantages provided by the short-throw projectors. They eliminate the shadows, glares, and reflection. This is because very high-quality lenses power them.
#6. Total Cost of Ownership
No matter how good your projector is, it’s a liability if it won’t last for more than a few years. Most schools are faced with tight budgets and should consider projectors with extended life spans.
One way to avoid changing projectors every year or two is to get a projector with less lamp wattage per lumen. It provides greater energy efficiency and saves money on lamp replacements in the long term.
Another excellent tip to reduce overall maintenance cost and cost of ownership is to choose projector models with an extended lamp life of over 5,000 hours. Moreover, investing in dust filters proves to be cost-effective as filters extend the life span of lamps which are costly to replace.
#7 Miscellaneous Features to Consider
Besides the above-listed features, you must also take note of the following features before buying projectors for classroom use.
- Audio: You will need good audio like all the content today requires audio to enhance the message. But, not all projectors have audio. On the other hand, some may have low-quality audio that is not audible in large classrooms. So, ensure your projector has a high-quality audio function.
- Long Lamp Life: Longer lamp life means lower projectors TCO. This is especially true in heavy-use classrooms.
- Portability: If you often need to share resources between more than one classroom, portability is an essential factor to consider. LED projectors are best for portability as they often weigh below 2 pounds.
- Connectivity: At Least one HDMI port is a must for higher connectivity. Some educational projectors also come with dual HDMI for easy setup and installation.
