I recently ran a F2F workshop for elementary preservice science teachers to introduce them to SMART Boards and to get them thinking about how best to use this technology with students to enhance science teaching and learning. As a way to organize activity centres, I created a wiki.
For 1 hour, the preservice teachers, in groups of 4, worked through 4 activity centres: SB1, SB2, SB3, and SB4. Each “SB” wikipage followed the “5E’s” science instructional model: engage, explore, explain, extend, and evaluate. This was a deliberate attempt to model how the 5E’s could be used to frame a lesson, since they would soon be learning about the 5E’s instructional model in their science education class.
I took a Piagetian approach – having students work on their own, then with a partner, and finally within a group of 4 preservice teachers. Thus progressing from invidividual to socialized thought. As the students worked through the tasks outlined on the various SB wikipages, they often had online videos that they could view on their own. They were instructed to complete the “explore” tasks in pairs and also to “extend and evaluate” their new learnings by discussing within their group of 4 to connect these learnings with science teaching strategies. “Homework” consists of adding these connections to the wikipages’ “extend and evaluate” sections, and asynchronous discussions about this may take place via the discussion forum accessible by clicking on the “Discussion” tab at the top of every wikipage.
The F2F portion of the class went extremely well. The preservice teachers were immersed in the SMART Board material presented, and as I was dropping in on their conversations, I could tell that they were looking at these resources through the lens of science educators. Did I succeed in situating them in context of teachers considering how best to use a technology for science education? I think so! They have until December 9, 2010 to complete their homework, and I’m looking forward to seeing how this community will take shape online.
Piaget, Vygotsky, Situated Cognition
Where Piaget asserted that children developed from the individual to the socialized (i.e. nonverbal autistic thought –> egocentric thought & speech –> logical thinking & socialized speech), Vygotsky argued that children developed from the socialized to the individual (i.e. social –> egocentric –> inner speech).
In situated cognition theory, activity and situations are integral to cognition and learning.
Vygotsky’s developmental theory and Situated Cognition theory can indeed work in tandem! These theories imply that:
Learners need to be situated within a collaborative learning context so they may co-investigate socially, eventually leading to internalized learning for each individual.
These co-investigation activities must be authentic tasks, situated within the context of the subject domain of study, such that learners see themselves as practitioners of that domain.
Both #1 & #2 can be done face-to-face (F2F) or online, but I always think that a blended model (e.g., F2F + online) works best.
Mitra’s SOLE and Granny Clouds
Having read about Piaget and Vygotsky’s somewhat opposite theories of child development, it has made me give more thought to Sugata Mitra’s TED talk about The Child-Driven Education:
The idea that children will collaboratively learn with digital tools they’ve never used, heard of, or seen before; inspite of purposeful lack of instruction and scaffolding – is evidence to me that collaborative learning is natural to the human condition. This is incredibly profound! Furthermore, Sugata Mitra’s work seems to support Vygotsky’s developmental theory, rather than Piaget’s; as it seems that the children in his studies developed their skills and knowledge socially before the new knowledge became internalized within each individual child.
In his TED talk, Mitra mentions 2 quotes from Sir Arthur Charles Clarke, that I find very profound:
“A teacher that can be replaced by a machine, should be.”
“If children have interest, then education happens.”
The second half of this TED talk is particularly intriguing. Sugata Mitra’s work on Self Organizing Learning Environments (SOLE) and the Granny Cloud. He informally organized children into small groups and gave each group a set of questions, as well as the freedom to access the internet with 1 laptop, discuss amongst their group, drop in on other groups, and no other scaffolding. He’s found that such informal groupings and vague scaffolding sets the stage for children to self-organize as a learning community, producing deep learning. His Granny Cloud work involved 200 volunteer English grandmothers who regularly taught English to children in India via Skype.
Mitra Vs. Situated Cognition
Mitra’s SOLE work is in sharp contrast to my classmates’ (Scott J.’s KEC note #1286 and Chad L.’s KEC note #1310) and my own thinking (KEC note #1404), that collaboration skills need to be explicitly taught. In Mitra’s SOLE work, this is clearly not the case! Is it possible, that by explicitly teaching collaboration, we stifle the degree to which children can collaborate effectively and learn deeply? It also interesting to note the absence of any situatedness in Mitra’s SOLE work. In fact, all of the learning tasks that he presented to various populations of children in various countries (India, Italy, England) were intentionally out of context and in some cases, not even in a language that the children knew! Perhaps then, situated cognition is not a necessary component of effective/deep learning, merely an enhancing component?
Mitra’s speculation: “Education is a self organising system, where learning is an emergent phenomenon…”. He estimates that it will take 5 years and under $1 million to prove this experimentally, and that’s what he intends to do. Mitra’s theory is a direct contradiction to Brown, Collins, and Duguid’s “cognitive apprenticeship” model (1989), where learning is embedded in activity and deliberate use is made of the social and physical context to immerse learners in the culture of the knowledge domain under study. The one idea that Mitra’s work and the Cognitive Apprenticeship model have in common is that learning is supported by collaborative social interaction and social construction of knowledge. As previously noted, Mitra’s work also contradicts the notion of “situated cognition“, in which activity and situations are integral to cognition and learning.
So who’s right? There seems to be supporting evidence for all arguments! Perhaps it’s a question of efficiency. If we leave learners to collaboratively self-organize, they will learn deeply if given enough time. If we situate (via cognitive apprenticeship) and scaffold learners’ collaborative learning, they will learn deeply, perhaps in less time?
Finally, Mitra emphasizes that the future of educational change is “A question of attitude, not technology”, and breaks down “The Arithmetic of Change” for us:
1 billion children
100 million mediators
10 million SOLEs
This indeed is an exciting and optimistic outlook for education! Perhaps there is hope yet of rocketing the education dinosaur into the 21st century…
