Schemas and Adult Learning

Recently I had was telling some of my Facebook friends about my plans for school. Christine Pence, whom I met at a conference a few years ago, asked me this:
Clare Shappee Dygert Christine -- I'm hoping my thesis will be on using ASL as a schema to reduce cognitive load in asynchronous e-learning. Whatcha think?
Christine Pence Hmm..could you expand a little on this? Are you thinking about the approaches to learning ASL as in your blog article? http://dygertthinkingoutloud.blogspot.com/2010/08/asl-handshapes-and-schema-learning.html Or, are you thinking about generalizing the design of asynchronous learning content? Do you have a specific academic content environment in mind?

Once I got over the thrill that someone A) read my blog and B)actually thought about it and remembered I had written, I thought about Christine's question.

Schemas (or schemata), as they are discussed in the Memory and Mind chapter, by John P Clapper ("Category Learning as Schema Induction") that I mention in my ASL Hand Shapes and Schema Learning blog post are a little different than what I am considering for my research. They are related, though. Schemas, as John Clapper uses the term, refers to categories of information. Students learn the characteristics of the category and are able to sort new information, determining if the new information is in or out of the category. This corresponds to the "concept" type in my instructional design model. (You can read more than you probably want to know about my model here: http://dygertthinkingoutloud.blogspot.com/2010/01/instructional-design-model.html).

What I would like to investigate in my research is whether or not the structures and grammar of ASL  -- use of signing space, time line, for example -- can be utilized by the graphical presentation of content in asynchronous e-learning as a schema, and would using it as a schema reduce cognitive load and make learning difficult content easier for signing learners.

To get to that question, there are a lot of other questions that have to be answered. How should I measure cognitive load? There seems to be some controversy about that topic. What features of ASL would be most useful to be used as part of a schema? How would that schema translate to graphical presentation of content?

The Chair of the Psychology Department warned me that my research question is more like a dissertation than a thesis.  It does probably have a life-time of work in it. But I think that is a good thing, don't you? If, in the next two years,  I can get the questions listed and understand what work has already been done on this topic, and find an ASL linguist who is willing to work with me, then I will consider the next two years well spent.

Segmenting, Signaling, and Weeding: Improving Learning from Educational Video

It's always exciting to find out that something I have believed to be true actually is true, and there is research to support it! Today I read a wonderful journal article by Mohamed Ibrahim and Pavlo D Antoneko, both affiliated with Oaklahoma State University. The paper is titled, Effects of Segmenting, Signaling, and Weeding on Learning from Educational Video. The study used hearing students and focused on dual channel processing of video and the cognitive load problems that arise, particularly for novice learners without domain knowledge. I believe there are many good take-aways for content that is being developed for deaf learners.

Ibrahim and Antonenko tested three strategies that seem to improve knowledge retention: segmenting, signaling, and weeding.  Breaking the content into smaller pieces allows students' working memory to  Signaling means that the students are notified when a piece of content is important. Weeding refers to removing all superfluous content. 

The core problem is that when novice learners encounter video instruction, it tends to be delivered all in one big piece. It has to be swallowed whole, or not at all. In addition, if the student is a novice, without domain knowledge, then he has to try to figure out what is important and should be remembered, and then where that knowledge should be remembered. So, Ii the content is too long, for example an hour instead of 5 minutes, the student's working memory can't manage it. By contrast, when a student encounters a difficult text, the student can usually stop it, or think about it.

Segmenting is the practice of chunking the video. When the 5 minute video ends, the student must do something to get the next piece. Just this is enough to give his brain the time to consider and store the content.

Signally adresses a problem that novice learners have. Without domain knowledge, the student has to determine what is important, and what is not, and where each part of the knowledge fits, locically. Signaling notifies the student when something important is happening in the video. Not having to make this determination for themselves, when they don't yet have experience reduces the cognitive load on the student, and results in bettter retenion and learning.

Closely related is the problem of weeding. Weeding removes all superfluous material so again the student is able to understand what is important and what is not. Removing this material also reduces the cognitive load for the student.

The concepts of segmenting, signalling, weeding are critical to the instructional design model I'm assembling for teaching business skills, particularly concept and principle content types, to deaf professionals.

A Child's Right to Her Language and Our Responsibility as Her Ally

I'm at Camp Mark Seven, a camp located outside of Old Forge, NY that offers programs for Deaf people of all ages as well as KODAs (kids of deaf adults) and hearing people who want to improve their signing skills. I'm here to do just that. This is my second year. It's wonderful to be in a place were I can use ASL exclusively.

Today we heard little about the Deaf experience and what it was like for our teachers to grow up as part of a minority culture. Like many people who use a language other than English, my teachers experienced aggressive pressure to not use their natural first language, ASL.

I have no wish to co-opt the Deaf experience. That experience is one I will never have. But as a member of a minority culture, I do share the general experience of not being part of the dominant culture.

Our culture, as Americans, is one that values white, able-bodied, hearing, straight, English-speaking, slim, young, christian, Protestant people before all others. I realize that some of my friends who are white, able-bodied, hearing, straight, English-speaking, slim, young, christian, Protestant people might feel that they themselves value people that are different from yourselves. To that I say,well, that's probably why I love you. But you only have to ask a few of you "different" friends to hear some rather sad or shocking stories. Yes, and not from 50 years ago, either. From right now in 2010.

Even some of my friends that are part of a minority group may say that they themselves have never felt undervalued. To them I will point out that this kind of pressure can be extremely subtle. It doesn't have to be a sign that says, "We reserve the right to deny service" or "whites only." In someways that kind of under-valuation is easier to deal with because it is so obvious. When instead, it is wrapped in a cloak of a parent's love, it is so much harder to see. What good parent wouldn't want her child to have every advantage, including the advantage of being in the majority culture? But when that means the child is robbed of her natural language and full membership in her culture of origin, it is a profound and deep wrong.

Every person has a basic and inalienable right to be who they are. And most fundamental is the right to their own language. In my mind, depriving children of this is no less than a type of genocide and must be fought as furiously. Those of us who speak the majority language but understand this truth must be unflinching allies in the struggle to maintain the language rights of those around us.

Learning from My Deaf Teachers

Last July I joined the National Technical Institute for the Deaf in Rochester, NY. Because of NTID, there are quite a few Deaf folks in Rochester, so I had some causual experience of seeing people sign. But I didn't know very much about the culture, and never really thought about how my instructional design "played" to a Deaf audience. Our content was captioned, so it was accessible, right? Wasn't that enough?

When I started to dig into the work at my new job, I decided that I wanted to develop an instructional design model for creating online learning for Deaf adults. It only took me a few minutes of watching my old e-learning to realize that it was woefully poor, if you did have the sound turned on. It lost most of it's meaning and the captions just didn't work to fill the void. But beyond that, I want to develop a model that actually works best for Deaf learners, and doesn't just have access tacked on as an afterthought.

So, it seems to me, that a good place to start is to observe good Deaf teachers. I am assuming that a Deaf person would know the very best how to teach a Deaf student. Lucky for me, I spend an hour a day, four days a week with such people -- my ASL teachers.

We have two languages at NTID: English, and ASL (American Sign Language). I have the opportunity to attend ASL classes and also to work with a tutor twice a week. I have a very long way to go to master this lovely language, but I am making progress.

I have had two different teachers for my ASL classes, and they are both really excellent. They are Sam Holcomb and Barbara Ray Holcomb. I have observed four things that they both do. I am going to assume that these are common practices of excellent Deaf teachers.

1. They don't assume that because they are broadcasting, I am receiving. They make sure I am attending before they communicate. I have started noticing my own communication patterns, and I see that I have a working assumption that because I am talking, you are listening. Of course that's not true -- how many times have I said something, only to discover that the recipient of my communication wasn't listening. Then I have to (after expressing frustration!) repeat myself. Barbara Ray and Sam signal that they are ready to begin -- then check to see if I am making eye contact with them - attending to them. They do that with everyone in the class, all 10 - 15 of us. And if someone isn't ready, they wait.

2. Barbara Ray and Sam both check for understanding after they communicate something. They look right in my face to see if I have understood what they are saying to me. If I don't actively communicate back that I understand, by nodding, saying 'ok' or 'yes' or 'right' -- they communicate right to me and keep doing it until I understand. I can't just zone out and not pay attention because they are checking to see if I am following at every juncture.

3. Both teachers will use a variety of ways to communicate new information -- fingerspelling the word, signing it, and sometimes using pantomime or pictures. Sam frequently explains how the sign might have evolved. It is amazing to me that I have developed the vocabulary that I now have almost completely by this method. Can you imagine learning Spanish at the earliest, most basic level without using English? I can't. Yet, this is how we have learned ASL.

4. The curriculum is entirely material that I need to do my job. It is completely relevant to my everyday existance at NTID. We do learn a little about the daily life of Deaf folks, and a little about Deaf culture, and I find that interesting. It helps me to understand how to modify my communication to be better understood by my Deaf clients and colleagues. But by and large, the stuff I am learning is what I need to survive, on the job.

You may be reading this and thinking, "Well, that's not very ground breaking -- that's just good teaching!" and you would be right. However, in my experience in all levels of education, from primary school up to graduate school, I have rarely had teachers who actively communicated as well as these two people do.

I am going to continue to observe Barbara Ray and Sam, and am going to try to observe some other Deaf professors here. I feel like there is a lot of gold here. Watching them is going to help me to devleop my instructional design theory, and after that, develop the best e-learning ever for the Deaf.
