Genetic Engineering Challenge – How can scientists develop a type of rice that could prevent vitamin A deficiency?

Parts of rice diagram

This analysis and discussion activity begins with an introduction to vitamin A deficiency and a review of transcription, translation, and the universal genetic code.

Several questions challenge students to design a basic plan that could produce a genetically engineered rice plant that makes rice grains that contain pro-vitamin A. Subsequent information and questions guide students as they learn how scientists use bacteria to insert desired genes, together with an appropriate promoter, in the DNA of plant cells.

In a final optional section, students evaluate the pro and con arguments in the controversy concerning Golden Rice.

Golden Rice – Evaluating the Pros and Cons

This activity engages students in evaluating the evidence and arguments related to Golden Rice and other possible strategies for preventing vitamin A deficiency. Students use this information to develop evidence-based conclusions about Golden Rice and the prevention of vitamin A deficiency. Students also develop questions that could provide important additional information for evaluating the arguments in favor of and opposed to Golden Rice and related policy proposals. In addition, students analyze how two reasonably accurate articles can present totally opposing points of view on this complex policy issue.

adults really get in the way: an analysis of education via unsupervised adventure (in The Phantom Tollbooth)

He noticed somehow that the sky was a lovely shade of blue and that one cloud had the shape of a sailing ship. The tips of the trees held pale, young buds and the leaves were a rich deep green. Outside the window, there was so much to see, and hear, and touch -- walks to take, hills to climb, caterpillars to watch as they strolled through the garden. There were voices to hear and conversations to listen to in wonder, the special smell of each day...His thoughts darted eagerly about as everything looked new -- and worth trying. (Juster 255-256)

The Phantom Tollbooth by Norton Juster is a classic piece of children’s literature, published in 1961. A timeless and revered tale, it is not only enjoyable and educational, it also advocates the importance of appreciating and being aware of the world - the environment - around you. For this reason, and because of its educational nature and narrative, it is a fantastic environmental education tool for young people. Gauged at around a 5th-6th grade reading level (by Scholastic, etc) and recommended for ages 8-12, this chapter book is full of challenging words and word play that must elude most children who read it (many of the expressions went right over my head when I read it in 4th or 5th grade), making it equally enjoyable for adults.

"What does citizenship mean?"

In Levinson's "No Citizen Left Behind"  as the students converse about Bush's intentions, Levinson had superior doubt before realizing her students were partially correct about 9/11. Reading their sentiments did not surprise me at all, for the fact that 1. I share a neighborhood and city with the students in this piece and I did not know the New York Bourroughs or the Pentagon and as a child, and 2. I shared what seemed to be common knowledge in our community: That Bush was not fond of us. Our parents said it, Kanye said it, voting said it, Hurricane Katrina said it; so to me the students did not sound ridiculous, they sounded quite aware. Today it seems the message blacks recieved from their president in 2004 is the same message they are getting from their legal system in 2014.

Productive Emotion

The Boler Chapters were interesting to think about. The role of emotion in the classroom has always been an interesting subject for me. I’ve always found that the classes that that had more emotional tension, classes I’ve been upset about the discussion or felt like I spoke from the heart very often have been the most rewarding and I was never really sure why that was. In the chapter 7 reading, the idea of empathy and testimonial readings as more than passive, but as an active was to both identify emotions in the classroom and recognizing that “I am not you, and that empathy is possible only by virtue of this distinction”. Boler makes a strong distinction between pity and empathy saying that pity is about your own vulnerabilities, not about the other person, which makes it seem useful that empathy be brought in the classroom for education. Often I feel like when I speak with my feelings in class that the only person who benefits is myself, almost therapeutically, but if students practice empathy then we can grow together in acknowledging emotions. Empathy explores beyond just what emotions are being expressed but also asks why they are being expressed.

If feel like this chapter made an important distinction for me about why empathy and active emotions are vital for a class, not only to understand each other, but also to understand power relationships that cause those emotions and that not all experienced are experienced the same.

Small Classes : Privilege

One of the lines in the readings in 'A Pedagogy for Liberation' that stuck to me was "the right to have a small discussion begins as a class privilege". It took me back to high school where all of my friends were scrambling to get into a large universities and I was the only one who was applying to small liberal arts colleges. My peers and the school administration did not understand why I wanted to go to a small liberal arts college and have undermined my decision to attend Bryn Mawr College. However, when I shared my classroom experiences to my friends over facebook, they expressed a hint of jealousy because they never had an opportunity in class to speak up or have a dialogue with the professor. Their voices would get lost in the crowd and they never had an opportunity to build a relationship with the professor whereas at Bryn Mawr, I could engage with professors easily inside and outside of the classroom. Though my peers were at big name colleges and were lauded for their decisions, I now understand that I am privileged to have the opportunity to engage with my professors. Friere stresses that education is not simply the relaying of information from the teacher to a student, it is the level exchange between the teacher and the student that makes education an art form and a learning opportunity for both parties.

Response to Shor and Freire!

 Shor and Freire’s piece on dialogical method of teaching was a very different format than what I am used to reading. They were having a dialogue about dialogue! I enjoyed the unpacking of their conversation though. There were three points that were made that stood out to me the most. Two of those points, I found slightly controversial and I had to read and understand to clear my way of thinking up. The last point I totally agreed with.

            First, Ira states, “the right to have a small discussion begins as a class privilege.” At first, I found this point troubling. I thought, “Just because someone is in a lower class does not mean that he or she does not have the right to engage in a small discussion.” However, as I continued to read, I understood Ira to mean that the higher the status, the more likely they are to enroll their child in school with an intimate environment because they can afford to do so. In contrast, lower status people enroll their child in bigger schools, with more people in the classroom. As a result, it is harder for these teachers to gain control of the crowded classrooms, so they are more likely to resort to “monologue or teacher talk, in the transfer of knowledge approach” because it would be harder for the teacher to engage every single student in dialogue.

Dialogue Reflections: Class, Learning, Culture

I’m coming away from reading Friere’s and Shor’s A Pedagogy for Liberation with three central themes I’d like to discuss further:

1)      I thought the acknowledgement that “The right to have a small discussion begins as a class privilege” (p. 98) was really interesting, and sadly often true. The authors discussed this reality in terms of resources, ability to have small class sizes, etc. but I think this pedagogical reality is also a function of the false (or what I view to be false) notion that students have to “learn the basics first,” before they can converse and have rich, meaningful dialogues. I’d like to further discuss how this emphasis on promoting dialogue in the classroom can be used draw students in and engage them while also learning content and skills, as opposed to only coming as a privilege, after the fact.

 

2)      I appreciated the concept that dialogue prompts the teacher to also engage in continuous learning: “Dialogue is the sealing together of the teacher and the student in the joint act of knowing and re-knowing the object of study” (p. 100). I agree that through dialogue, the teacher can learn just as much from as they teach to students—if done well. But I do wonder, is this a guarantee? Can a teacher successfully promote dialogue without being open to learning themselves? What are the implications of this?

The Civic Empowerment Gap, Universal Values, and Working in or out of a System

At a general, my-personal-values level, I think that I believe in Levinson’s point that the “civic empowerment gap” is a big issue. In a country where we put democracy on a pedestal and where the structures, policies, etc. of our country are decided by a so-called democratic process, it really doesn’t work if huge groups of people simply aren’t being heard.

In light of the Boler chapter on teaching socio-emotional skills and subsequent class discussion about the problems with teaching “universal” values and skills, however, I found this chapter more troubling and confusing. I think that there is a lot of potential for undermining the lived experiences of students, for undermining the action that they do take in their lives, and teaching them to incorporate themselves and work within a structure that is actually really detrimental to them (and is, in fact, a reason why they are less civically engaged).
