The Rectangles of my Mind

The Rectangles of my Mind

Individual rectangle desks are a mobile and modular instructional strategy for using student classroom furniture to create both individual work space as well as a variety of group work configurations.

… Like a circle in a spiralLike a wheel within a wheelNever ending or beginningOn an ever-spinning reelAs the images unwindLike the circles that you findIn the windmills of your mind.

–Alan and Marilyn Bergman, The Windmills of Your Mind

A Little History

The 1960’s and the All-in-one Desk Combo

My 1960’s childhood desk from probably 1st grade – 8th grade was a single unit seat attached to a rounded rectangular angled desk top. The maple laminate top opened from the bottom from a long front hinge to reveal a tub-like cavity for books and stuff. I can’t stress enough “the stuff” part- candy wrappers, baseball cards, marbles, etc. along with the California issued text books for that grade.

A teacher would say, “Get out your math books,” followed by 30 students simultaneously opening their creaking desk lids, then rifling through papers, books and “the stuff” to locate that math textbook usually found at the bottom of the pile. Many of my teachers would make their class clean up their desk tubs every Friday afternoon which if you times that by say your elementary school years, probably equals too many hours wasted on that one activity alone.

These desks were like mini-tanks with the tub and base legs all made out of U.S. steel. All designed not to move an inch from the industrial-straight rows of the factory to the corn rows growing in the fields. Now this wasn’t all bad. I do remember a margin of personal space lost in later configurations, so let’s hold that thought for later in the year 2020.

The 1980’s-90’s and the Two Student 24″x48″ Desk with Dual Book Boxes

Sometime in the 1980’s, somebody came up with the old idea of cramming two students right next to other in 24 inches of personal space. Maybe it’s just me being from California where the minimum size for all public education 1st-12th grade classrooms is only 960 square feet. Even in 2024, most California school districts still build their new classrooms to the State’s minimum requirement. So if you take 36 students in a typical California secondary classroom you can get 18 of these desks with 36 chairs with little to no room to spare in that minimum sized space.

Most teachers who still have these desks in the 2020’s now turn the book box side away from students. Some even tape them shut with cardboard as to eliminate the book box as “trash can” experience. In fact, teacher feedback has cured me of suggesting the student desk “book box” or “tote” storage, for any grade. In 2024, many elementary teachers prefer “cubbies” for managing personal student storage. Now, most elementary and secondary students come to school with their own backpacks. Like many teachers, I’m a big fan of the backpack hook option for each student desk.

The 2000’s and the Shapes Craze

Around 2008, as an Educational Technology Resource Teacher I (and thousands of other educators close to a funding source) started changing up traditional classroom furniture to compliment the fact that many school districts were almost at the tipping point of one-to-one mobile device computing. Not to mention a national movement towards collaborative and project-based learning coupled with National and Common Core Standards.

Actually, in the late 90’s and early 2000’s trapezoid and then triangle desks started appearing in classrooms. By the 2010’s, every K-12 furniture manufacturer had almost every kind of shape you can imagine in their roster. I was all in, and tried many different shaped desks in K-12 learning spaces.

Eventually for me, it came down to observing even some of the most progressive young teachers getting frustrated putting together the puzzle piece furniture for group work. Maybe I was wasting their time and patience, if not also eating up their precious 960 sq. ft. of space.

The 2020’s and my Covid Epiphany

In 2014, I was so into creating collaborative student work groups that I called my early consulting business, Collaborative Learning Spaces, then Groupwerk®. But in 2020, we all added “social distancing” to our collective vocabulary. For me, Covid-19 was a game changer in how we needed to design K-12 learning spaces for the present and for the future. Rest assured, that future will certainly include pandemics and/or other local, state and national public health conditions.

I came to realize that we needed to get back to smaller simpler individual desks. One, smaller desks that could be easily moved to provide space, individual work, and social distancing. Two, these same individual desks could also be brought back together to form a variety of small to medium work groups shapes. I thought of the rectangle shape, and in the windmills of my mind, drew four desks coming together as a pinwheel.

The Rectangular Desk

The rectangle shape takes us to the past, present and future. It’s long and short sides give it a mobile and modular flexibility in both form and function.

Here, I’m going to focus on the Wisconsin Bench (WB) Plymouth series of rectangular desks, and then show you five familiar group work configurations that any teacher and class can easily set up or reset.

WB Plymouth and Plymouth II (with Belly Curve) Rectangular Desk Top Models

WB Plymouth Rectangular Desk Top Sizes and Laminates

The Plymouth Desks come in three table top sizes:

  • 20″ x 27.5″ – Standard sitting classroom leg adjustment sizes
  • 20 x 28.5″ – Some sitting, and sit to stand leg adjustment sizes
  • 24″ x 36″ – This size works well for larger rooms such or makerspaces. The larger table top is also ideal as an ADA desk.

WB Plymouth Leg Options with Rock ‘n’ Roll Names

D&D Learning Spaces loves WB student desks because they provide three different leg models that I personally memory associate with my own rock ‘n’ roll youth.

  1. ELO – Remember them as, “spider legs.”
    Musically, if you grew up in the 70’s, you’ll remember ELO as “Electric Light Orchestra.”
  2. ELP – Remember them as “pin legs.”
    Musically, ELP is “Emerson, Lake and Palmer,” a big 1970’s band.
  3. ELS – Remember them as  either “screw-adjustable legs” or “fixed legs.”
    Musically, ELS is “Electric Lady Studios” in New York where Jimi Hendrix recorded.

Height Adjustable Ranges with Glides or Caster Options

Note – The EJA basically stands for elementary grades leg height-adjustable range.
The ADJ basically stands for secondary grades leg height adjustable range.

The Rectangles of My Mind

Let’s finish with five popular classroom configurations using a rectangular desk shape. Here we will show a classroom/learning studio with up to 36 students, including:

32 – (20″ x  28.5″) Plymouth sized desks, and

4 – (24″ x 36″) Plymouth sized ADA desks.

This inspiration comes from D&D’s work with the stakeholders for the new construction of Compton High School, set to open in 2025.

and… Let’s end with the traditional classroom configuration that I started with in first grade way way back in 1961, and still popular today at many high schools.

D&D’s Teacher Presentation Stations (TPS)

D&D’s Teacher Presentation Stations (TPS)

A Teacher Presentation Station (TPS) is a height-adjustable mobile table equipped with power and wire management. From the TPS, the teacher orchestrates teaching and learning with their laptop typically connecting to an interactive LED display and document camera. 

First, A Little History

When I was in elementary school in the 1960’s, most of my K-12 teachers had their desk in the front corner of the room. These desks were typically made out of solid oak and had anchored many a school year.  When the teacher was not teaching at the front chalkboard, or at their relatively new overhead projector, they would most likely be navigating the class from their desk.

Speaking of that “new” overhead projector, it was really the first analog “interactive” AV equipment in the classroom. It allowed teachers to present acetate transparencies of basically any lined drawing, or their own handwriting while facing students. As a visual learner, I just loved images used in class whether they were transparency illustrations to help me learn concepts, or educational filmstrips and movies. I always volunteered to thread and operate the filmstrips or 16mm film projectors while I sat right next to the projector to troubleshoot film jams. I had that job locked down by 5th grade. In fact the picture above, reminds me of my 5th grade teacher, Mrs. Erickson with her red curly hair. You didn’t mess with Mrs. Erickson.

Years later as an Educational Technology Resource Teacher for San Diego Unified School District, I participated with colleagues in developing a teacher presentation station that would integrate all the new classroom digital technology.

In the 1990’s, the table top video projector entered the classroom. The video projector sitting on a separate AV cart was connected to a desktop computer from another table all plugged together with an extension cord and VGA cable strung across the floor. The computers image was then projected onto a pull-down screen, probably from the same era when I was running the film projector back in the mid-1960’s.

In the early 2000’s, technology really started to enter the K-12 classroom as the teacher got a laptop computer and a large Interactive Whiteboard (IWB). Table-top video projectors evolved into short-throw video projectors that could be mounted above the IWB. This was a game changer because we could put all the wiring in the front of the class, close to the wall, and away from the middle of the action in the classroom.

From the wall, we then could connect the interactive whiteboard located in the front center of the room to a laptop and document camera resting on a new kind of powered media table. This table was most often located several feet away in the front corner of the room just like Mrs Erickson’s old desk. We dubbed the table the “21st century teacher desk.” In just a few years, the majority of the traditional old wooden teacher desks were removed from the classroom.

The shift had happened. Schools integrated the laptops, interactive whiteboard, doc cam and projection system to the teacher’s new desk. We called the desk, the “Teacher Presentation Station” or simply “TPS.” Not only could the teacher present, but students could come up directly to use the interactive whiteboard, or use the presentation station with their student mobile device to present to the class. 

I took the two pictures above around 2009, where we integrated the following items to make our district standard presentation station.

  1. Custom Bretford Table 24″ x 48.”
  2. The table legs were screwed to a fixed standing height so the teacher could stand or sit in a height-adjustable task stool.
  3. A document camera was mounted on the white laminate table which served as a neutral color balance for the doc cam.
  4. The table also had a wire management tray underneath to hold a power strip and connect all the tethered wires to the ceiling projector, interactive whiteboard, wall power, DVD player, and classroom audio and wireless microphone system.

The vendor who helped me design the custom presentation station teacher desk, even included a drilled hole to secure the doc cam with their lock-down kit, was none other than D&D.

As always, technology keeps moving forward as the Interactive Whiteboard (or IWB) has now evolved into a LED Promethean Interactive Display with up to an 86″ diagonal size eliminating the need for a video projector altogether and servicing replacement lamps.

D&D Learning Spaces has been a part of this classroom technology history that continues today as a furniture and AV vendor for K-12 schools.

In the past year, D&D has been working with Wisconsin Bench a leading manufacturer of educational furniture. Together we have crafted a “new and improved” presentation station table that enhances teacher ergonomics. We are happy to now introduce, three different self-height adjustable bases connected to a writable surface powered table top. 

The New Table Top

 Just like our original 2009 Bretford table, D&D’s new Teacher Presentation Stations (TPS) are designed for orchestrating teaching and learning with a teacher laptop, doc cam, and LED interactive display.

All three TPS models include the same new table top that maximizes the table space and includes:

  • Custom 28” x 48” Table Top *Note- The Pin Leg Adjustable (PLA) Table is 24″ x 48″
    • Formica Writable Surface – Liquid Glass (actually any laminate surface you want)
    • Legrand Table Top Access Box with 4 outlet Power Strip 15ft.
      Excellent for holding a teacher’s laptop AC Brick and cords – all top-loaded with no more bending under the table to plug in and out daily!
    • Pencil Drawer 
    • Slate Grey  – Armor edge 
    • Legs – Smooth Silver
    • 12″H x 35” W Perforated Metal Modesty Panel with cable management trough
      (including Velcro Cable Management Kit) 
    • 4 Locking Casters

The TPS is available with a task stool sold separately.

D&D’s Three Teacher Presentation Stations (TPS): Leg Base Options

  1. TPS – Pin Leg Adjustable (PLA)
  2. TPS – Crank Height Adjustable (CHA)
  3. TPS – Pnuematic Height Adjustable (PHA)

The Leg base options are presented in a progressive good, better, and best soluton based on our K-12 customer’s needs and budget. 

1. TPS – PLA (Pin Leg Adjustable) 

The Pin Leg Adjustable (TPS-PLA) model is our entry-level solution in height adjustment. This is are most economical TPS as most teachers will set the pin legs to their personal standing height from 26″- 40″, and then leave it there permanently for sitting in a raised pneumatic task stool, or for standing too.

2. TPS – CHA (Crank Height Adjustable)

The hand Crank Height Adjustable (TPS-CHA) model is our middle level solution in self-height adjustment. The hand crank easily raises and lowers the adjustable legs to the exact user’s height for standing or sitting in a task stool. The handle retracts under the table and is interchangeable from left to right sides.

3. TPS – PHA (Pneumatic Height Adjustable)

The Pneumatic Height Adjustment (TPS – PHA) model as our top level solution in instantaneous self-height adjustment. The handle control is unique for pneumatic height adjustable tables in that it is flush mounted underneath the table. This design hides the mechanism as most teachers appreciate this feature.

The Teacher Presentation Station Task Stool (sold separately)

The Office Master BC47-SDU Teacher Task Stool is our go to pneumatic height-adjustable chair used for sitting or standing at the Mobile Presentation Station. This product features:

  • Fabric Black Vinyl – Grade 3 3P30 Noir
  • 8″ Cylinder rather than the standard 10″ (Allows more people the opportunity to put their feet on the floor if they desire) Note- The “SDU” signifies the 8″ cylinder
  • Seat Height  23-31″
  • Casters Hard or Soft
  • Overall Height  42-55″
  • Warranty  7 year limited

    The Flexible Classroom Begins with Dynamic Furniture.

    By providing self-height adjusting furniture with casters, teachers have more options in creating an enticing learning space for students that is both mobile and modular. Look to D&D Learning Spaces to help districts and schools design their own multimedia presentation system for students and staff and provide the integration services to put it all together!
