Classroom Projectors: Pull-up Projection Screens
A pull-up projection screen is perfect for schools since they can be lowered and raised in seconds to expose the blackboard or start a projector presentation. These types of screens are fairly inexpensive and not too difficult to install.
Classroom Projectors: Portable Projectors
Many of today¡¯s data/video projectors are smaller than a laptop. These projectors are perfect for the traveling salesperson, but may not be the best choice for classrooms. If your data/video projector will be used in one or two main classrooms, then we do not recommend choosing the most portable projector you can find. Aside from a higher cost, the smaller the data/video projector is, the more likely it is to be stolen. Projector theft in classrooms is at an all time high. The larger the projector, the more difficult it is to conceal and steal.
Classroom Projectors: Visual Aid
Multimedia projectors allow teachers to provide diverse content to all students in the classroom at once, allowing students to have a visual and colorful learning experience during a given lesson. These multimedia projectors are perfect for this generation?s visually oriented youth because they help make abstract concepts easier to understand.
Classroom Projectors: Cost of Ownership
The projector cost of ownership over the life of the projector can vary significantly from model to model. It is important to buy from an experienced dealer who knows the history of the manufacturing and model for service issues and lamp history. Just because the digital projector looks like a steal when you buy it, you may dump a lot of money into the digital projector with new lamps and service issues.
Classroom Projectors: Alternative Way of Teaching
By not forcing a teacher to rely solely on books, a classroom projector makes more educational information available to students. It changes conventional habits and rituals in the classroom. In fact, some survey participants believe a multimedia projector could soon replace the chalkboard and overhead projector.
No matter how you will be using your multimedia projector in your classroom, you can be sure that it will benefit both the students and teachers.
Classroom Projectors: Kensington Lock
If your projector will be on an Audio/Visual cart, rather than ceiling mounted, we recommend purchasing a Kensington lock for the projector. Most projectors have a slot somewhere on the data projector that is designated for a Kensington lock. Attaching a lock to the data projector and securing it to the A/V cart will eliminate any thoughts of theft. In addition, it may save your projector from falling to the floor if the cart is accidentally bumped.
Classroom Projectors:Overall Benefits
The main reason that educators upgrade their overhead projectors and whiteboards to multimedia projectors is to improve the performance of their students. Multimedia projectors certainly do an exceptional job in helping students learn, but that¡¯s just the beginning. Classroom multimedia projectors provide many additional benefits that educators quickly realize once they start using them.
In a recent study, educators rated various benefits resulting from the use of classroom multimedia projectors. The result were as follows:
- 98% of respondents said that projectors provided a significant improvement in student attention
- 94% reported significant presentation quality
- 94% reported easier editing of presentations
- 94% reported a greater ease in presenting information
- 90% reported a significant improvement of understanding information
- 80% reported a significant improvement in retention of information
- 74% reported a significant overall time savings
- 62% reported a significant overall cost savings
There are numerous reasons to purchase a multimedia projector for your classroom.
Classroom Projectors: Makes Teaching Easier and Better
Instead of having students crowd around a computer, the entire class can view one big screen without difficulty. The multimedia classroom projector has made the teaching of Internet-related subjects and the demonstration of new software applications much easier - heightening students? awareness and expectations, while captivating their attention and increasing their motivation. The multimedia classroom projectors also accommodate the electronic submission and viewing of student work.
Classroom Projectors: Customized Curriculum Applications
Multimedia classroom projectors are being used for a variety of curriculum-specific applications. In language arts, a teacher linked up to an author?s Web site to provide greater insight and impact to a reading assignment. A science teacher created a PowerPoint presentation to demonstrate a frog dissection. In social studies, a teacher developed a tornado presentation for increased audio and visual impact. For math classes, multimedia classroom projectors have been used to teach students how to work with spreadsheets, calculate formulas, and utilize charts and graphs. Athletic departments show practice and game films, as well as illustrate plays, with the ability to pause, reverse and update them spontaneously.
Classroom Projectors: Brightness
Classrooms can be deceiving with regards to brightness because of fluorescent lights. These lights are extraordinarily bad for the projected image. Fluorescent lights tend to make a room much brighter which will make your classroom projector appear much dimmer. To counter the effects of classroom lighting, make sure that you purchase a classroom projector that is bright enough to leave the majority of the class lights on. This way you can maximize your lesson plan and minimize the ¡°goofing off¡± that happens when you turn off the lights.
Classroom Projectors: Projectors and Video Conferencing
Multimedia projectors + Videoconferencing = Long distance learning for disabled students as well as opening course availability districts that have fewer options. Today¡¯s videoconferencing is lightyears ahead of what it used to be. Today¡¯s video and images are clear and the audio is stereo quality. A school can use a multimedia projector in conjunction with videoconferencing to teach one on one to a student, or to an entire class.
Classroom Projectors: Projector Resolution
If you will be projecting PowerPoint type presentations with large fonts and graphics, then your classroom can save money by purchasing an SVGA resolution projector. If you will be using the projector in a high school or college class, we recommend spending a little more for an XGA resolution projector. XGA resolution projectors are designed for more detailed presentations that are perfect for math and science curriculum.
Classroom Projectors: Projector Throw Distance
Can it be read from the back row? The rule of thumb is that the type in the projector presentation must be at a minimum of 24pt type to allow everyone in the room to read it.
In addition, the distance from the back row to the screen is the diagonal measurement of the screen times 6. As an example, if you have a 60¡± diagonal screen (5 feet), then your maximum distance is 30 feet from the screen. Any further from the screen, and you would not see the image well.
Classroom Projectors: Projector Inputs / Outputs
It is important to make sure your new school projector will accept data from all the primary sources you want to display. If you are using a VCR or DVD player then an S-Video input is a must. If you want to connect your school projector to external speakers, then audio outputs are important.
