Reflections on Teaching 1

I truly believe that had I received the training I have had at Harvard during the past 4 weeks prior to my teaching career, I would have been a much more effective teacher. (Well, or perhaps I needed to experience to fully understand the implications of what we're studying and doing). It is absolutely amazing to be in the hub of educational research. I am truly blessed, and I feel a need to communicate what I've been learning. Blogging is, of course, a rather fragmented approach, but a nevertheless valuable one. I think I would just like to take all of the information I've learned and travel around the States and give presentations. A liaison for the MBE program? A Neuroeducator Liason for MBE (Mind, Brain, and Education) at Harvard. There. I've created my own job :)

Anyhow, I have extracted a few ideas from the following articles: 

Carey, S. (in press, 2010). Precis of The Origin of Concepts. Behavioral and Brain Sciences.

Fischer, K. W., & Bidell, T. R. (2006). Dynamic development of action and thought. In R. M. Lerner (Ed.), Theoretical models of human development, Handbook of child psychology (6th ed., Vol. 1, pp. 313-399). New York: Wiley. pp. 313-336, 347-399

Learning is really dynamic and not the traditionally seen linear approach. We have commonly seen education as a linear system (imagine a ladder where each step up signifies learning new skills, understanding concepts, etc.). This ladder metaphor does not truly represent what happens in the brain; rather, individuals go through a series of progressions and regressions. Before a new concept is fully understood, and individual will go through a series of "dips" before acquiring the new material. We build knowledge on past experiences and past knowledge. In essence, a boot-strapping mechanism is in place (Carey). When learning a new concept, students have what's called a placeholder (Carey) for the knowledge they do know, and then they grapple and negotiate with the new concept (a series of ups and downs) until it is embedded in their minds. 

As Fischer discusses in his essay, “When individuals are beginning to develop a new skill, they shift between two different representations or two different strategies, each of which is only partly adequate to the task” (as qtd in Fischeràpg. 355). Therefore, learning any new concept takes quite a bit of time and periods of uncertainty are to be expected.

Here is a graph that shows these progressions and regressions in various individuals:


 Pretty cool, huh?

Here's what happens to students' learning over time when they receive support (optimal level) vs. no support (functional level). Notice the HUGE leap over the course of years! We really need to have smaller class sizes, implement RtI, etc. to make this happen for each student!


And then I leave you with one final thought:

“To flourish, living systems must be more than just organized. They must be dynamic. Systems must constantly move and change if they are to carry out their functions and maintain their integrity and their interrelations with other functioning systems. A system that becomes static—unable to change and adapt to varying conditions—will quickly parish” (Fischer, Bidell, p. 308, 2006).

A living system applies to not just biological beings, but to social and mental entities as well. If something does not adapt, it will fall apart. The world of education is changing, and I couldn't be more excited about what this means for our society :)

There are so many other cool models I could post here, but I need to do homework for now.

Walden Pond 1 of 2...


Today we visited Walden Pond. Why Walden Pond? Well, Kasia took particular interest because the great writer Thoreau spent the greater part of his writing time at Walden Pond. We spent the greater part of the day exploring, and Kasia was really excited that we were experiencing the place where Thoreau did most of his writings. Well, after meeting the park ranger, he assured us that, although Thoreau did pass through here, he actually did most of his writings in the other Walden Pond. You might be asking yourself: two ponds in Boston that have the exact same name? That's exactly what we were thinking. And, yes, there are two ponds in Boston, and they both share the same name.

Even though this isn't the famous Walden Pond known for hosting Thoreau, we still had an awesome time exploring and experiencing a lot of cool things. Here are the pictures we took:





 We spent a few hours here reading and having lunch.




 Can you spot Kasia?
 The park was full of huge rocks that were everywhere. There were many that were even bigger than this one.

 We spotted an island. So what did we do? We claimed it for ourselves of course!
 If you look closely you can see a trail of rocks. These rocks (which were probably thrown in by various explorers who had come before us) made it easy for us to hop across the water and explore the island.
 Kasia about to embark on the journey across.
 Kasia officially claiming the island. She was also making a variety of chanting noises during this pose. Unfortunately I'm not able to record voice at the same time I'm taking a picture on the iPhone.
 Huck Finn? It was too dangerous to cross the water with shoes; one slip and that could jeopardize the rest of our explorations (which included a trek up an enormous hill to Stone Tower!). So, naturally, I ditched the shoes and hopped across!
 View from the island.
 Can you hear me now? Kasia testing her cell phone range...





 The view from Stone Tower.





 All of the windows had bars on them. Apparently the tower has been closed for 40 years, and they just recently reopened it. We happened to come by when the park ranger was there and he was kind enough to open it for us.
 Kasia at the very top.


 The city we left behind (Boston). It's hard to believe we were this far away.
 The tower itself! I didn't get a picture of the hill we had to climb to get here. And, upon seeing the hill, we almost didn't make the journey, but we sure are glad we did!


 The tower was actually built back during the great depression for reasons unknown. Perhaps a fire-lookout tower?
 I stopped for gas, and while I was fueling I turned around to the car and Kasia was gone. I looked around and saw an ice cream store, so I knew exactly where to find her!
Not only were these the 'small' cup, but they were buy one get one free. All of this ice cream (coffee and oreo & black raspberry) for $4.

We're planning on going to the 'real' Walden Pond where Thoreau did most of his writings sometime this season. However, from what we've heard, we both agree that were Thoreau alive today he would much prefer this pond! We'll definitely be coming back. And, if you're ever in the Boston area you should definitely check this place out. The Stone Tower is worth the visit alone.

Plum Cake

I will attempt to make a plum cake tomorrow (before church, and before I lock myself in the Gutman Library and study all day). The purpose? 1) I love to bake 2) I can have a snack while studying 3) there are leftover plums 4) Lulu (my kitchen-aid) hasn't been used in awhile.

So if you're an MBEer, and you're reading this, you might need to redirect your attention to studying, or finding a slice of this cake. 

Plum Cake
from Everyday Food
3/4 cup unsalted butter, room temperature, plus more for pan
1 1/2 cups plus 2 tablespoons all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup packed light-brown sugar
1/2 cup granulated sugar
3 large eggs
1 teaspoon pure vanilla extract
2 teaspoons finely grated lemon zest
1/4 cup sour cream
3 plums, halved, pitted, and cut into eights
confectioner’s sugar, for dusting

Preheat oven to 375. Butter an 8-inch cake pan and line bottom with a round of parchment. In a large bowl, whisk together 1 1/2 cups flour, baking soda, and salt.
Using an electric mixer, beat butter ans sugars until light and fluffy. With mixer on low, beat in eggs, one at a time, until incorporated; beat in vanilla and lemon zest. Beat in 1/2 the flour mixtures, then sour cream. Add remaining flour mixture; mix until just combined.
Spread batter into pan and smooth top with a knife. In a bowl, toss plums with 2 tablespoons flour and arrange over batter.
Bake until cake is golden, about 30 minutes; loosely tent with foil and bake until cake pulls away from side of pan and a cake tester comes out clean, about 35 minutes more (Note: I found the cake only needed an additional 10-20 minutes). Let cake cool completely in pan. Run knife around cake edge and remove cake from pan. Dust with confectioner’s sugar before serving.
