ArchExchange

The Virginia chapter of the America Institute of Architects hosts a conference every November that is called “ArchExchange East.”  It’s a fabulous learning experience for me and my students.  Most of our department attends the event.  I’ve included photos of some highlights.

Drawing (on) Gravity

Sometimes gravity is an architect’s friend.

In fact, architects can use gravity to human advantage in all sorts of ways.  In Ecology class today, I showed some diagrams of systems that use “thermosiphoning.”  That’s a fancy word referring to gravitation pull that moves fluids (like air or water).

The idea is that warm air (or water) rises and cold air (or water) sinks… because a  liquid is heavier and more dense when it is cold.

So, we can let gravity do the work if we think a system through.  Sometimes we need to move liquids in directions they don’t naturally want to go, and then we need to add electric pumps or fans to our systems.

Today, I showed my second year architecture students a tromp wall system as well as a diagram of an open loop solar hot water system.  In that type of system, you let the sun heat the same water that you will use to shower, wash dishes, or drink.

I also showed a few diagrams of basic heat exchangers… like the one in a car.  That one takes the heat from the combustion process and uses it to warm the air in the car without bringing in the “smog.”

The students were seeming to “get” the ideas, but they didn’t seem particularly jazzed up about them.  (I knew that because they were fidgeting and clearly wanted to text.)

To get them involved, I turned posed a problem for them to solve.

I asked them to pull out a sketchbook and combine the solar collector and the heat exchange into a single diagram.  They needed to figure out how you could use water with water with glycol (i.e., antifreeze) in it to collect the sun’s heat and then use that same liquid to warm the water for someone’s shower.

The challenge was to transfer the warmth into potable water without tainting it.  A couple of students caught on fast. After everyone had given it a try, I let them help each other.  More and more people got it.

At about the same time, I asked a four of the students who caught on quickly to draw their diagrams on the board and then explain how they worked to the class.  We all put our heads together to analyze the designs.

Gravitational Pull

cabins 2

Hampton University’s second year architecture students are learning about gravitational forces and lateral loads by designing post and beam structures using a simple kit of parts (and adhering to a lot of fairly complicated rules).

The intention of the assignment is for students to learn about cantilevering, stacking, and hinging.  They also have to respond to environmental factors and work together in groups to enhance the site design concept developed by another student in the studio.  You can see one of the site design models in the photos below.  The cardboard frames you see represent the structural systems of small cabins that nestle into the site design.

I’ve asked them to build the structures at such a large scale (1″=1′) so they can really get the feel of what the various structural components are capable of doing.  Once they achieve suitable concepts, they will model their frames in wood.

Fingers cross that that will happen by Wednesday!  Thanksgiving is just around the corner… only three weeks of classes left to go this semester… so much to learn, so little time.  They still have to have the interior space, design building skins, and illustrate their designs with diagrams and measured drawings.  All that, in addition to completing their Physics, Architectural Representation, Architecture History, and Architectural Ecology course work.  Whew!

Strolling Freemason

Hampton Roads is lovely this time of year!  Here are some snippets from my quick post-yoga walk through Norfolk’s historic Freemason district.

Full STEAM Ahead, Virginia!

Discussing STEAM subjects: Caroline Martin, Dr. Judy Stewart, Orlando Robinson, Dr. Michelle Claville, Romdon Roopchan, and Dr. Shannon Chance.

Big things are happening in the world of STEM education in Virginia.  Two enterprising educators, Caroline Martin and Dr. Judy Stewart, have founded the Virginia STEAM Academy.  Their public, 4-year residential program in Science, Technology, Engineering and Applied Mathematics is set to open for its inaugural cohort of students in the fall of 2015.  Last summer, Judy and Caroline conducted a summer program to get the ball rolling.

They have been working on the Virginia STEAM project since November 2010, and I’m happy to say that I’ve had some level of involvement since February 2011.  Although I took a year away during my Fulbright fellowship, a Wednesday meeting  on Hampton University’s campus helped me catch back up.

I’m fascinated by two specific aspects of the planning Caroline and Judy are doing: (1) securing and preparing facilities on the former Ft. Monroe that will house 1000 high school students and 75 teachers (who will live on-site with the students) and (2) designing the curriculum to support quality learning and innovative teaching.  They are such innovative thinkers and they know how to get things done!

Their vision for the school is remarkably aligned with the research I’ve been doing on integrating design thinking into engineering curricula and on tracking learning outcomes that accrue as a result of hands-on, problem- and project-based learning.

This Academy is going to open a while new world of possibilities for Virginia and her citizens.  My sister, Heather , was lucky enough to attend the Governor’s School for Science and Technology in Roanoke when she was in high school.  However, the daily commute — an hour each way — was a real strain on her and the other three students from our county who attended with her.  This new residential school will take the burden of daily commuting away, allowing the students and teachers focus on learning and generating new knowledge.

I am thrilled  the school will be here in Hampton Roads, and just a stone’s throw from Hampton University’s campus.

This Academy offers an ideal setting for the study of history as well as STEAM subjects.

Cheers from W&M

The William and Mary School of Education students I spoke with (about my Fulbright research) last week sent you a wave.  My iPhone was acting strangely and I captured only the tail end of their wave, but I assure it was wholehearted.

A sincere Virginia hello, from us to you!

A Tasty Bite of Elephant

Last night I met with the class on Student Development Theory at The College of William and Mary.

The class on Student Development Theory at The College of William and Mary.

I visited alma mater last night, The College of William and Mary, to speak about cognitive development theories developed by William Perry, Marcia Baxter Magolda, King and Kitchener, and the like.  I was asked to highlight how I incorporate these theories in my research and teaching.

This was an optimal time to give such a talk, because I’m gearing up to conduct a phenomenological study of students’ experiences of collaborative, trans-disciplinary, problem-based learning.  Last night’s talk got my mind moving in that direction.

The people in the picture above are working on graduate degrees in Higher Education; several of them shared  ideas and recommendations for the design of my proposed project.  At least two of them are using phenomenological methods for their dissertation work.  Their enthusiasm for my plan raised my own energy level and got me psyched to start work.

I’d had some nagging questions about how to best protect my research participants (i.e., “subjects”); the W&M students helped address my concerns.

I’d also had difficulty making time for this project because of its sheer scale.  I was trying to do too much at once.

I devised a workable plan during my drive to Williamsburg and got good response to my idea.  In essence, I’m now following the rule that if you want to eat an elephant, you’ve got to proceed one bite at a time….

I’d been completely overwhelmed by trying to analyze data from 30+ participants.  So, I’ve determined to focus in on one group.  I can extend the work over time, but a group of six is appropriate for a phenomenological study (and a more reasonable way to digest this elephant).

So, I’ll look closely at one group of six students who worked together as a team with impressive results.  Each of these students documented the team’s design process in writing across the course of a semester.

I’ve already done quite a bit of analysis on what they wrote, and that allowed me to make a purposeful selection.  In this case, I know that more than one team member experienced  powerful (pivotal or seminal) instances of learning.  I want to find out what factors caused those changes.  I’ll be looking at how the six team members experienced the collaborative design process in the period leading up to significant “a ha” moments.

I hope that the results will help educators (including me) prompt that type of “deep learning” more often.

I can extend the work to look at other groups later.  And, as Dr. Jim Barber (the instructor of record for last night’s course) pointed out, I can also extend the study in the future (to make it “longitudinal”) by tracking down members of the group and conducting follow-up interviews.

I always enjoy visiting the W&M School of Education and yesterday was no exception.  After arriving at the School of Education’s brand new LEED-Gold building, I admired the fall colors and gabbed with a former classmate (Sharon Stone) and my mentor (Dr. Pam Eddy) before heading into Dr. Barber’s class.

Can’t wait to visit again!
