Just Read Some Books And Call It A Class

Today at lunch, several colleagues and I were discussing a unit in our freshman and sophomore English courses known as the limited free choice book project, which equates to varying levels of choice depending on the teacher. I like to think of the way I frame the project in my class as "guided" free choice. The book choices are not limited or governed by me, but I move the students through a process focusing on making an informed choice about the book they're going to read.

Anyway, what I want to post about today is what I offered to the group over teri-tofu and chicken long rice soup: a class that was simply independent reading and blogging. This idea comes after a very successful three weeks of guided free choice reading and blogging in my class (and a free choice project). After the process of choosing books, we studied facebook and came up with a protocol for leaving comments and expanding others' ideas with conversation. This led to some really impressive student blogs. In addition, we studied the elements of books: first chapters, centers of gravity, questions that authors seem to be trying to answer in their chapters, metaphorizing, amongst other things. It didn't matter that we weren't reading the same stories because we had a common language for talking about literature. Along the way, students get a sense of their reading interests, strengths, and challenges, monitored and guided by me when necessary. I used the metaphor of a book universe that they create and explore. And it was all about using brain research to scaffold activities offering students differing paths to literacy and expert reading.

So many heads in books.

So, for the course I'm imagining, my colleagues challenged me on whether students could read graphic novels, children's books, Twilight and Harry Potter. The classic questions. So I thought I'd have them read from all genres: fiction, non-fiction, classic, graphic novel, fanfiction, etc., in any order they please. This is going to lead me to learning more about fanfiction, as well as books that accompany video games.

Are there courses like this out there? What do they look like? How well do they work?

Learning And The Brain: Keynote by Larry Cahill Ph.D.

I tried to tap into Dr. Cahill's research on emotional memories in my last post, but here are the notes I took during his keynote at Learning and the Brain conference in San Francisco, which also addresses gender, hormones, and brain hemispheres. Some of my notes are in my own words and some phrases are Dr. Cahill's. I apologize for not quoting well here.

Basic Premise: Memory (the brain function) creates self. And, emotion disproportionately sculpts the brain. So, how, again, can we leverage this for effective teaching and learning? And how can this knowledge empower students?

Part I: Background – Brain Mechanism of Emotional Memory
•Memory is active, constructive, and based on orientation. Throughout the building process, perceptions are created.

•Amygdala is the structure in brain that's central for making strong memories of emotional events. It works together with stress hormone response: during and after events, feeds information back to brain. Amygdala works harder in emotionally arousing situations; doesn't care about neutral situations.

•Stress hormones enhance memory storage.

•New technique for measuring response is brain imaging, which is leading to awareness of difference between men/women brain.

•Activation happening on different sides of the brain: right side in men; left side=only women in response to stress hormone.


Part II: Sex Influences On The Brain

•What does it mean for education and learning?
•Classical difference, no debate:
On average men can rotate images better (visual fluency).
Women have more verbal fluency.
Many differences on the psychological level.

What about on the brain level?

  • 1970 hippothalmus was difference.
    • Differences are ubiquitous
    • Incluences everything
  • Differences now:
    • Size of brain regions
    • Levels of neurotransmitter
    • Females have lower levels of serotonin
    • Women more depressed 2 to 1; drugs boost it for depression
    • Uncovering differences that aren't understood yet
    • Hippocampus cell experiments with knocking out molecules
    • Results in memory deficits in male mice, not female
    • Cell cultures – differences on this level
      • Neurons die, why?
      • Different depending on where they came from: male or female
Part III: The Blinders Come Off: Sex Influences On Brain Mechanism Of Emotional Memory
•
Sexes are not two different groups; two groups with overlap
• What are the findings?
  • Right hemisphere is gist of situation
  • left hemisphere better at details
  • Amygdala can be blocked, beta blockers
  • Experiment with emotional story:
    • Females remembered gist
    • Men remembered details
  • There are memory differences:
    • Women have better memory than men in general
    • Better for details
    • Outperform on these kinds of tests
    • Left side is more engaged when emotions are involved
    • What about without emotional stories?
      • Amygdala works with left side in women, right side in men

more notes soon...

Leveraging Emotions For Learning And Brain-Based Activities With The Cather In The Rye


(This post has been under construction for a week (that's how busy it is here). Hence, the dates are off a bit)

I got back to Honolulu yesterday after attending the west coast Learning and the Brain conference in San Francisco. There's a lot to process and disseminate after three days of learning about the latest in neuroscience research and how it's applicable to education and specific classroom practices. Of course, the first people I wanted to talk to about all this were my students. So I shelved Catcher In The Rye for a day (maybe for a few more days) to empower them with some understanding of how they can leverage their intelligences, learning styles, emotions, and the plasticity of certain parts of their brain. Here's what I did:

Activity:
Monday morning, I announced pop quiz on the first three chapters of Catcher In The Rye.
Brain-based connection:
As they reacted in fear to my announcement, I explained that I wanted to let them in on some secrets about their brain and the way they learn. Their emotional and physical reaction to my announcement was a change in their brain chemistry. Cortizol had washed their brain, hindering their ability to learn and access their long-term memory. The best thing they can do about it is drink water.

Activity:
I explained that this was a two part quiz, and there was no way to fail. Part 1: List ten summary statements about what they read over the weekend. Look for details.
Part 2: They had to clap out a rhythm together, then go around the circle giving new facts about the chapters.
Brain-based connection:
The rhythm engages the right brain, the summaries engage the left. To do both forces connections between the two hemispheres, which foster better long-term memory learning. Not to mention that it was fun and active. We continued to talk about leveraging their brain chemistry and identifying what they can do for themselves.

Transition:
Now that I had their interests piqued, I wanted to connect more brain secrets to effectively exploring The Catcher In The Rye, so I asked them to free write about specific emotional highs and lows in their lives. The homework extension was to collect visuals symbolic of their highs and lows and construct a "high/low" collage.

Extension/Connection:
The next day, we had a gallery walk to view everybody's collages. Specifically, I asked the students to look for and record patterns they see in the collages. Next, I asked them to translate their observations into questions about what it's like to be a teenager. They came up with questions like: why are friends so important to happiness? Why are so many emotional lows connected with anxiety over grades? What is the importance of outdoor activities in a person's life? And so on.
My pitch was that now that they are invested emotionally in a thinking about their experiences as a teenager, they are better equipped to interact with the novel they're reading.
Brain-based connection:
I learned that the most effective learning environment for teenagers is social, interactive, and emotionally engaging. Reading, as my students agreed, can easily be none of these if not properly framed. So not that they were engaged, I led them through some active reading strategies that would help create interaction with the text and put them at the center of the reading experience.
