Lemann Fellowship – Thank You Letter

As part of receiving the generous fellowship, we are encouraged to write a thank you letter to our sponsors… here’s mine:

Dear Mr. Lemann,

I am a Masters candidate at the Learning, Design, and Technology (LDT) program at Stanford, writing to you to express my gratitude for your generous contribution towards my studies. It is an honor to be recognized by Stanford and the Lemann Fellowship and be part of such a great initiative to help Brazilian public education.

My Stanford experience so far has exceeded all of my expectations. I did not know it was possible to learn so much in such a little time. I did not expect the classes to be so rich, interactive and collaborative as they are. I am continuously amazed to see what we are learning about education being applied to ourselves during the classroom activities. I am in awe of the stellar level of the professors, leaders in their fields and mentioned continuously throughout the research papers that we read.

I started a small school that teaches mobile app development in São Paulo 6 years ago. The more I learn here, the more I know how much I can improve my school in terms of curriculum, teacher’s effectiveness, promotion of knowledge, assessment, and student motivation. I already know that I will be able to apply the knowledge being acquired here onto my school. Yet more importantly, I am seeing how complex education is. It is probably the most complex problem humanity faces nowadays. I believe it is far easier to colonize Mars than to educate the world effectively. To start off with, we need educated engineers and scientists to be able to go to Mars – therefore, education is the basis of our civilization.

My focus here will be on teacher professional development (PD). I believe it is the first step towards educational reform. Without better PD, it is impossible to change the system since teachers are the catalyst of this transformation. Online learning promises education at scale but it has been proven that it alone is not sufficient. Humans learn better from humans. We need coaches, facilitators, guides, and motivators to keep us on track, on point, and continuously moving forward in our learning progression. Teachers need to understand how to promote a growth mindset in students, how to explain the content appropriately, and to assess student learning in realtime.

For opening my eyes, I thank you. For creating the Lemann Fellowship, I salute you. For persevering with your business in Brazil and around the world, I admire you. If only we had more politicians, leaders, and agents with you vision in Brazil…

Sincerely,

Lucas Longo

My Learning and Teaching Story

When I was a kid a was fortunate enough to have many Lego kits and a father who is an architect. I was always fascinated at how he was able to think of a space in his head, draw it on paper, and the build it. Legos offered me that experience – especially when I moved to their Technique series. I was never interested in playing with Lego as a storytelling arena or a fantasy world environment. I was interested in building the models offered in the instructions in able to learn what specialty pieces I had and then repurpose them into new formats and functions. This thought me enormously about spatial thinking, mechanics, gears, electric motors, and reverse engineering. I clearly remember my mother going nut when I disassembled the TV set just to look at how it was built inside. Without my experience with Legos, I am sure I would never have been able to put the TV back together.

Moving ahead in time, I found myself teaching Lego robotics as an extra curricular activity in high schools. Lego Techniques had advanced into Lego Mindstorm, where you could finally program behavior, use sensors, and outputs. It increased the learning curve for the kids who had to first learn about structure, reinforcement, and forces that acted upon what they were building. Then they had to understand about inputs, outputs, thresholds, activation and deactivation. Finally they had to put it all together into a ‘robot’ and program its behavior. What I learned from this experience was that teaching is the best way to learn. I quickly realized this and suggested to the kids who were further along or finished their own project, to help their neighbor. The class came alive and the projects rapidly moved from frustrations to energetic show and tell.

Notes:

Equity – it is not only about making materials available, it is also about training the teachers well, and most importantly, promote a growth mindset on the students.

Example of 2 day cares in Brazil – both rated equally, funded equally, and with good teachers. The difference was in the socio-economic level of the students. The higher income students were more demanding of the teachers. Lower income students would remain quiet and felt it was not their place to demand for attention or to say that they did not know how to do something.


 

In class Reading: 

Papert, S., & Solomon, C. (1971). “Twenty things to do with a computer.”

“Only inertia and prejudice, not economics or the lack of good educational ideas, stand in the way of providing every child in the wolrd with the kind of expereince of which we have tried to give you some glimpses”, p.40

My ‘new’ ideas:

  • Use the LOGO turtle to demonstrate Newtonian physics of mass, speed, friction, and acceleration.
  • Use the LOGO turtle along with 2 light sensors to look at a white strip on the floor and have the turtle follow the line on its own.

Discussion:

Should everyone learn how to code or should everyone learn how to use the computer?

Does a product’s ubiquity be a necessity for people to learn what is going on ‘under-the-hood’?

At the time of the paper, there was no internet and the integration of these simulations with learning goals were not explicitly stated.

At the time – the challenge was to teach the teachers on how to use this technology within their curriculum. The eternal problem of Teacher PD (Professional Development).

“Nothing could be more absurd than an experiment where computers are placed in a classroom and nothing else changed.” – Seymour Papert


Painting elephants: guided by their trainer through the elephant’s ear they produce great paintings. But this is similar to our educational system… the students produce results but are they really aware of what they are making?

Categories of technology

  1. Cost cutting: iPod did it for the music industry
  2. Making the impossible, possible: Computer graphics, a technology that made it possible to create new movies such as Avatar or the Matrix.

This is going to be a fun class 🙂


 

Post-It activity: What are learning technologies? How would you categorize them?

Core Mechanics – Week 1 – Reading Notes

Reading

Brown, A. L., & Kane, M. J. (1988). Preschool children can learn to transfer: Learning to learn and learning from example. Cognitive Psychology,20(4), 493-523.

Summary

Studies on how learning can happen through only one or few examples, both for children and machine learning. Explaining the one example leads to greater transfer, vs just looking at the example. Learn by teaching.

“In this series of studies we examined whether young children can abstract a general rule from examples and, if so, whether their learning is influenced by their ability to explain why the concept is an instance of the rule.”

Mental Notes

  • Video Games must be an effective way nowadays to test transfer in children.
  • Learn by teaching, by explaining – create a schema in your head prodcues learning.

Citations

“Transfer is not automatic but depends upon insight into general principles.”, p.495

“Telling children that problems are the same, without specifying how, is one of the methods that has promoted successful transfer in young children (CrisatI, 1986; Crisafi & Brown, 1986). Therefore, this obvious mention of the common action and of problem similarity should promote transfer if anything would; thus, the hint condition was regarded as a yardstick against which the other manipulations could be measured.”, p.500

“This means that the 3-year-olds show a reliable learning to learn effect only if they are encouraged to reflect on their solutions, either through discussions, instructing Kermit, or explicit prompts to problem similarity.”, p. 501

“Taken together the results of Studies 4 and 5 suggestthat examples are more useful in promoting transfer than the provision of an explicit statement of the general rule.”, p.512

“Taken together, Studies 5, 6, and 7 demonstrate the efficacy of having learners generate explanations of why an example is an instance of a concept.”, p.516

“Exposing children to a variety of transfer experiences teaches them to search for underlying commonalities.”, p.516

“If children spontaneously recall, or elaborate on why an example is an instance of a deeper relational mechanism, or if they are led to such elaborations by probing questions, they transfer readily. Elaborations and explanations provided by the subjects themselvesare more effective in promoting transfer than those provided by the experimenter, an effect reminiscent of the use of self-produced elaborations in adult learning (Reder et al., 1986).”, p.517

“Efficient learners prepare for transfer by engaging in reasoning processes aimed at elaborating knowledge. With experience, efficient learners develop a mind set to regard new problems, not as isolated examples, but as instances of a general class. Efficient learners come to expect what they learn to be relevant elsewhere. Efftcient learners perform thought experiments in which they actively seek out appropriate analogies. In short, efftcient learners understand some of the principles involved in learning and reasoning; they have a greater metaconceptual grasp of the domain ‘ ‘learning. ’ ’”, p.520

“Some think of using the computer to program the kid; others think of using the kid to program the computer. But most of them have at least this in common: the transaction between the computer and the kid will be some kind of ‘conversation’ or ‘questions and answers’ in words or numbers.” (Papert, Solomon, 1971, p.1)

Curriculum Construction – Week 1 – Class Notes

Class with Denise Pope again 🙂 Started with going over the course organization and trying to convince people to leave the class – only 30 spots for about 50 people in the classroom. Stresses out the amount of work this

What is curriculum? (Think – Pair – Share)

  • Establishes the learning objectives
  • A sequence of topics the teacher should follow in teaching the class
  • Teacher instructions on how to conduct the class
  • Presentation material to be shown in class
  • Content scope within a developmental stage
  • Proof of completion through assessments
  • A slice of a bigger body of knowledge

 

Core Mechanics – Week 1.2 – Class Notes

(insert class slides here)

Transfer:

  • Applying a skill learned in one context in a different one
  • Relational reasoning must occur to overcome different surface features.
  • For it to occur, one must be able to understand the underlying structure or “deep features”.

Negative Transfer – when you use a ‘learned’ skill in an analogous situation incorrectly.

Analogies:

  • How to increase creativity using analogies?
    • Analogies in scientific discovery are usefull to tangibilize abstract concepts
      • Kepler – speed of planets to derive gravity
      • Dunbar – biological analogies
  • Strong prior knowledge is essential for creating effective analogies
    • Learning facts therefore sometimes is needed

Exercise: create analogies for the following:

  • A robbed safe
    • A pearl removed from a closed shell – NA
    • A person who’s lover has left – HQ
    • A hacked database – NA
  • A light bulb blowing out
    • A candle extinguished by the wind
    • A tire popping flat
    • Collapsing while running a marathon
    • An overheated engine
  • A budding cocoon
    • A flower blossoming
    • A transformative chemical reaction
    • A chick being born
    • A sprouting seed

Structure coding of analogies:

“A robbed safe”

Not Analogical

  • Someone taking something out of a protected space
  • An empty box
  • A stolen wallet

Low Quality

  • Squrrel digging nuts
  • Expect something from computer and it’s broken, you can’t get it

High Quality

  • Cheating on a partner
  • Soldier coming back from war with PTSD

 

Asked people to create analogies, sitting or moving indoors or outdoors. From lowest to highest scores for High Quality Analogies:

  • Indoors – sitting
  • Indoors – walking
  • Outdoors – sitting
  • Outdoors – walking

So… study/create outside 🙂 Is that why Steve Jobs always had long walks as meetings?

From lowest to highest scores for Novelty of Analogies:

  • Indoors – sitting
  • Outdoors – sitting
  • Indoors – walking
  • Outdoors – walking

So… walking helps with novelty or divergent thinking.

=> Moving around outside improves creativity and thinking BUT most of Edcuation is done indoors with the students sitting around.


Analogy as a Core Mechanic for Transfer

Analogical Transfer

  • Initial learning – need to learn underlying structure of the base
  • Spontaneous access – need to be able to retrieve information

Example: The Radiation Problem

  • No previous story – 10% solved it
  • Spontaneous transfer – 30% solved it
  • Hint condition – 75% solved it

Method: Give them 1 analogue, 2 analogues and compare, principle, and/or diagram.

Result: 2 analogues + principle + diagram was the best. But mainly it is the 2 analogues that make the difference.

With 2 analogies, you are able to create a Schema to solve the problem.

But bad analogies can be dangerous leading to wrong schemas.

Entrepreneurship and Venture Capital

This is a GSB (Graduate School of Business) MBA class I got in… interesting first day with guest speaker Mike Maples

I am not sure I will take this class… my class load is impractical at this point and want to concentrate on the education courses – do them well.

This Thursday there will be another class and I will have also had taken the other classes I’m registered in for the first time.

By Friday I have to make a decision.

Brazilian Education – Week 1

Given the feedback from last quarter the teachers decided to discuss with the students how could we improve the the class, having more discussions and engagement with the content. Since each week we’ll have a different lecturer, it will be up to the lecturer to design this activity.

So the class today was a short overview of what content they want to cover and how might we do that.

Just occured to me that this is the hardest part about teaching well – is preparing a class activity that is engaging and participatory – instead of a mere lecture. Lectures are interesting but can be compared to watching TV… 5 minutes later you forget… unless you are deeply engaged with the subject matter and the stakes are high. When the stakes are low, you might want to establish a more interactive engagement.

Could a presentation software with some coaching do the trick?
