How Bright Should My Classroom Projector Be?

It’s back to school time here at Projector People!

Today’s lesson is on classroom projector brightness. How bright a projector do you need for your classroom? Will 3,000 lumens do the trick? What about 5,000?

It all depends on the lighting conditions.

Read on to learn how many lumens you need based on you classroom’s ambient light.

Key

Low ambient light* Controlled Lighting: If you plan to use your projector in a room where there are no windows, such as a basement, or if you use your projector primarily at night, any of today’s projectors will provide a bright image.

Low ambient light Low ambient light: Little to no light entering room.

Some ambient light Some ambient light: Some additional light in room. Slightly dimmed, window blinds leaking some light.

High ambient light Bright ambient light: Windows open during daylight hours, lights that cannot be dimmed like in an open office settings. Bright enough for audience note taking.

3D in the classroom

3D technology has come a long way since the days of those cardboard specs moviegoers wore to cinemas in the 1950s. Today we’re witnessing the rise of 3D from a novelty to a staple of movie theaters and home entertainment.

The technology is also moving into our classrooms. The manufacturing of 3D projectors has increased significantly, making the technology more available to K-12 educators.

Although not yet widely used, there are a few pioneering school districts implementing 3D. I was curious to find out if 3D in the classroom improves learning gains and what educators have to say about it.

Boulder Valley School District in Colorado has integrated 3D in four of its schools. THE Journal recently interviewed teachers there for an article titled “Taking Learning to a New Dimension” about the effect of 3D on students.

“I teach mostly biology and chemistry, and a lot of that information is hard to visualize, so 3D really helped them see in much more detail what I was trying to teach them,” said Boulder science teacher Kristin Donley. “As (the students) would do an essay question about molecular processes, for example, they were able to recall details much better from a 3D versus a 2D and were able to put those details in an essay.”

3D seems to go beyond the “wow” factor and encourages a deeper level of thought processes. Donley’s students, for example were able to demonstrate a higher level of understanding, and the use of higher order thinking skills.

Anecdotal evidence points to what could be called the “Toddler Effect.” Have you ever seen a very young child deeply immersed in play? Students are deeply engaged in a 3D lesson as they want to know more about what they are seeing, which leads to much deeper understanding.

Sounds like some of the early adopters of 3D are seeing tremendous benefits for their students. Are you an educator who has used 3D in the classroom? Share your thoughts below.

What students have to say about classroom technology

If you want to know how students learn, just ask them.

Projector People had the privilege to interview a few sixth-grade students in Ms. Janet Tolson’s math class at Seven Springs Middle School in Pasco County, Florida. We wanted to know what they thought about using technology in the classroom to improve their learning.

What do kids think about classroom technology? We got to find out.

We asked Rachel, a student in Ms. Tolson’s class, what technology she already uses at school to improve learning.

“We do research on the computer,” Rachel said. “One of my teachers has an interactive projector which helps me to understand things better. I have an iPad and can purchase books to read on it. My sister is in high school, and she has an iPad and uses it there. I also use technology at home for learning, like Study Island and Coolmath.com for math facts.”
 

When we asked what she thought it would be like to have all of her textbooks on a digital device, Rachel answered that while it would be nice not having to carry around a backpack, students might not be prepared to take care of technology devices. She also said she’d still like to use textbooks.

Emma, Ellen and Chandler from Ms. Tolson’s class provided us with more valuable insight. Here are a few of their quotes:

“Having an iPad would keep you from carrying books. We could get digital books from the school website. Kids would know how to use any device if their teachers know what websites to show us.”
 
Interactive projectors would help to visualize concepts, because the teacher can write on them.”
 
“We use the computer lab but are allowed to bring digital readers to school.”
 
“We use Study Island for homework.”
 
“Teachers should use apps so kids could play and learn.”

Short throw education projectors

Short throw projectors are immensely popular among our education customers. A short throw projector can be set up close to the screen, freeing up space in small areas. Due to their close proximity to the screen, short throw projectors eliminate light from shining in the presenter’s face and shadows from obstructing the image. The Hitachi CP-A301N and CP-AW251N are two popular short throw models.
