Letting the Student become the Teacher

Nathan

Prof. Marta Adair

Some people just shouldn’t be teachers. Then there is Marta Adair.

Professor Adair is a biology professor, chair of science education, and Director for Education in the Bean Life Science Museum at BYU. She truly understands what it means to be a teacher and what her role is in the classroom. I witnessed something in her Intro to Biology class that illustrates what a wonderful teacher she is.

She began a discussion on the topic of carbon dioxide emissions and global warming, a controversial subject wherever it takes place. A couple of students raised some questions that Professor Adair answered as best she could. Another student, however, raised his hand to share a few additional comments on the matter. It turns out that he had spent around 300 hours researching energy, carbon emissions, and nuclear power as a member of a debate team a year ago. His comments sparked additional questions from his peers. Realizing she was unprepared to answer such questions, she half-jokingly said – as many professors do – “Why don’t you just come up here and answer these questions?” to the student who knew a little more about the subject. Then a somewhat astonishing thing happened. The student stood from his seat, and Marta Adair took his place.

For the next 20–30 minutes, the class discussed the topics answering each others questions with help from two teachers assistants, the student now at the front of the room, and a few interjected comments from Professor Adair seated among the students.

As I sat there observing these interactions I was amazed at how naturally the conversation moved from one relevant topic to the next. The students, mostly freshman and sophomores, asked intelligent questions and offered information they found helpful. I could sense a curiosity that was fueled by the open and candid atmosphere. There was an organic and harmonious progression of thought. Minds were enlightened, misconceptions corrected, consciousness raised.

This experience contrasts those I have had on countless occasions in classrooms where the professor incessantly lectures on a pre-established set of “learning objectives”.

Marta doesn’t have a set agenda for her class, a list of topics that she must cover during the semester, or an established list of facts that her students must memorized. Yet, never before in my time as a student have I had such a desire to investigate, inquire, learn, and share what I know about a subject.

I once heard, in a meeting full of educators, that the Latin root educare means “to lead out.” Why, then, does the general approach to teaching seem so very opposite to that image? Instead, I see teachers who effectively push or pull their students into a narrow and specific group of concepts that have (questionably) been determined to be more important than any other, forcing them to memorize facts without understanding their meaning. How restrictive and boring!

Attempts to understand the broader picture and explore connecting facts are most often received with a look of contempt and the instruction to not “worry about that,” usually because “it won’t be on the test.” How narrow minded and empty of purpose!

The atmosphere in Professor Adair’s class is very different. She encourages her students to ask questions and rejoices when a student connects personal experiences with the topics discussed in class. Real, practical learning takes place and it is exciting!

I am reminded of the call by Jay H. Lehr regarding conference presenters:

“Let there be an end to incredibly boring [teachers]! They are not sophisticated, erudite, [experts] speaking above our intellectual capability; they are arrogant, thoughtless individuals who insult our very presence by their lack of concern for our desire to benefit from a [class] which we chose to attend.”

Sir Ken Robinson, a passionate educator himself, illustrates the great flaw in the ubiquitous prescription of content.

“It is education that is meant to take us into [a] future that we can’t grasp. Children starting school [in 2006] will be retiring in 2065. Nobody has a clue [...] what the world will look like in five years’ time. And yet we’re meant to be educating them for it.”

In a world that progresses as fast as ours, how can we be sure that the content we prescribe for the younger generations will be relevant in an unpredictable future?

Marta Adair is a leader. She cares for her students. Evidence to this fact can be found in the 60 students who she mentors, the effort she puts into the education program at the museum, and her family life. For me, her concern for the education of her students was manifest the moment she humbly became the student and allowed a student to become the teacher.

Do you want to see a great presentation?

Nathan

It’s not often that you get to see a presentation and think, “Wow.” I’m not talking about the “whoa dude! That was so awesome!” kind of reaction. What I’m talking about is when you know that the message you just heard was exactly what the presenter meant for you to hear, and that the whole experience was simple and clear.

I recently had this experience watching the keynote at Apple’s World Wide Developer’s Conference. Picture 10.png
Go ahead, chuckle, snort, you can even post a snarky comment about me being an Apple fanboy. It’s alright. Because it’s true. I love Apple and everything they stand for. I’m not saying that they are a perfect organization or that this presentation didn’t have any flaws (in fact, there were two obvious errors in this keynote). It’s just that their simple, direct approach to business, product design, marketing – and presenting – make it so that little, if anything, is misunderstood.

Go ahead and watch just a little bit of it.

Notice how there is rarely any text on the screen.

Beautiful, high quality images are used in place of bullet points.
Picture 9.png
Simple, easy to read graphs.
Picture 7.png
Transitions are used appropriately to create emphasis.
Picture 6.png
Not to mention a clutter free stage, large projector screen, the use of light humor, repetition, seamless transitions between speakers, and more.

Seriously, just watch a bit if you have some time.

PowerPoint Handouts Not Effective

Nathan

A while back, Mike Pulsifer pointed me to an article on Ars Technica: Study: class podcasts can lead to better grades.

The article, and the research done by State University of New York, focus on whether using podcasts as an extra study resource for students can improve grades. I am a huge fan of podcasts. Over the past couple of years I have learned an immense amount by listening to podcasts – from language, to photography, to brain science, and design. On iTunes U anyone can access lectures from some of the best universities in the country by downloading and listening to podcasts of each lecture. This is a great way to acquire knowledge or to get further study for a class you’re currently taking.

What I found even more interesting about this study was the method of teaching and study that wasn’t as effective: handing out printed copies of the lecture slides to students. As the author of the article notes, passing out PowerPoint handouts has become “all the rage” in many lecture halls, within or outside the academic world. In fact, two of my previous science courses are designed around PowerPoint handouts – every slide of every lecture for the entire semester is included in a “Lecture Guide” that the students purchase at the beginning of the semester (sometimes in lieu of a textbook).

What’s the problem with this?

PowerPoint slides are NOT notes. They should not function as notes. Not for the teacher and especially not for the student. Retention increases when exposure to information occurs across multiple modalities – listening to a lecture, reading a textbook, discussing a subject in a study group, etc. (You may be familiar with the idea of being a visual vs. kinisthetic vs. auditory learner.)

A printout of common lecture slides is not much different than the lecture – except that you probably aren’t having them read to you by a Ph.D.

But repitition increases recall, right?

Yes, that is true, but do not forget that certain modalities of learning are less effective than others. As Dr. John Medina points out, “the brain sees words as tiny pictures. Reading creates a bottleneck.” (Brain Rules, pg. 234)

This is just one more reason to do away with text on those lecture slides, replace them with images, and maybe even replace the handouts with a link to the podcast version of your next lecture.

Just Say No to PowerPoint Week

Nathan

I just discovered via Scott Schwertly of Ethos3.com that the second week in February is officially “Just Say No to PowerPoint Week.”

Scott linked to an opinion piece at the Daily Princetonian that explains it well.
It’s also covered by Nashua Telegraph and there are plenty of other sites mentioning it if you Google it.

So join in! Hopefully some posts on this site have helped prime you to “Just Say NO!”
