Most cases of bad grades and drop-outs turn out to be a mismatch between the

their own material for writing with teachers ensuring that they have enough

With digital medium, hyperlinked 'digibooks' can be composed, distributed and

[IAEP] Computer as a tool

2009-07-02 Thread K. K. Subramaniam
Hi,

This thread was spun off Re: [IAEP] Comments on David Kokorowski, David 
Pritchard and Mastering Educational SW

There are differences in the use of computers in schools between Sikshana 
(sikshana.blogspot.com) and Sugar Labs/OLPC. Sikshana's tech pilot is only 
three years old and will reach around 6000 kids (grades 5..7) across 120 
schools this year.

Our involvement in these schools, as community members, was child-centric and 
focussed on building basic skills set. Supplies shortage is a perennial issue 
in these remote villages. We introduced computers as digital authoring tools 
so kids never run short of 'supplies'. There was no pre-loaded content - no 
physics lessons, no cartoons, no quizzes. A 2GB USB flash memory chip issued to 
each kid served as a digital school bag. Etoys (customized for vernacular 
support) ran off the chip while others were installed on the hard disk.

The difference between OLPC/Sugar/SoaS in the separation of personal content 
from the rest of the stack. Computers are not networked, collaboration is 
physical. The machine, OS, GUI, software tools were all subject to change.  
Putting OS on the chip would have reduced space for project files and upgrading 
software on so many chips would be a logistical nightmare!  Our field office 
maintains a pool of computers (notebooks and desktops) from which schools can 
borrow as many as they can manage in the classrooms. Bite only what you can 
chew. This system allowed teachers and students to focus on authoring and not 
get bogged down by IT issues.

We didn't try to simplify GUI. It was not even localized though teachers and 
students knew very little English. We found that kids enjoyed the challenge of 
mastering GUI. They were thrilled to use the same 'computer' that IT folks use 
in their offices. English-Kannada dictionary got used heavily.  Undo became a 
much loved feature. They learnt LaTeX encoding to produce Kannada and Math 
text. Students formed teams to share 'tips and tricks'. Now teachers, across 
schools, are forming self-help groups to share their findings.

The new academic year has just started. In the prev one, around 75% of the

term exams).  Around 25% of the children were yet to record their projects. 
Schools closed (Apr/May) before we could dig deeper into the causes.
 Technologically: How many USB sticks failed? How many were lost/stollen?
None reported so far. For students, the chip is their most precious 
possession.
 Did the kids find any places to use the sticks outside of school?
Yes. Some kids do, when they visit their relatives in the city. BTW, computers 
are not tied to the school. With personal data separated from the 'machine', 
many teachers chose to 'issue' computers to children like books, so that they 
could 'work' during evenings and holidays or participate in science contests.
 Do you have any measure of how much content was created? Is there much
 sharing between schools? Do you have any advice on how to facilitate sharing
 of created content?
Our intention was to equip students with 'infinite supplies' so that they could 
jot down their personal ideas and stories not for creating content for the 
classroom.  Teachers did not venture to 'correct' mistakes in the projects nor 
use it towards grades so students could 'tinker' with their pet ideas withour 
fear or stress. We used the number of projects recorded on the chip as a proxy 
for the effort. See
 http://sikshana.blogspot.com/2009/04/digitally-literate-rural-students-
enter.html
for details.

Mentors from our foundation visited schools twice a week and helped them stay 
abreast of developments in other schools.

I remain vary of  'content'. I have seen too many cases of content of dubious 
value. The teachers and students are quite capable of creating their own 
content. If they need help, they contact us. That is why I stick to software 
like Stellarium, Etoys, LaTeX and Inkscape.

While early results are positive enough to spur us to cover all 120 schools 
this year, I remain cautious and vigilant. A program like this has to be run 
for many years before we can establish an enduring change in the learning

all that extra pain; else the initial enthusiasm will fizzle out. This ruled 
out many games, audio/video/picture work.

 What have been the issues preventing you from using Sugar? What
 blockers still exist which would prevent you from using Sugar?
LaTeX and Stellarium were two big show stoppers. We just wanted a 'digital  
kit' that children could use to read/write in their local languages 
(Kannada/Hindi/English). A lot of work in Sugar was focussed around UI and 
storage models but not in multilingual support and immersive learning.

We picked LaTeX because it allowed teachers and children to generate high 
quality text for vernacular and Math text. Children as young as 10 taught 
themselves LaTeX encoding just to be able to get high quality labels for their 
diagrams.

Local culture has deep ties into astronomy and lunar calendar. Stellarium 
offered an excellent way to connect classrooms to the skies. Students could 
directly observe planets and track their orbits. Events like the upcoming 
eclipse on July 22nd would have been missed in the past because of monsoon

 However, my point of making that clock was that each kid should make

An objective tick-tock is just one way to understand time. It is the kronos 
time. However, the round clock face stood for a different concept of time - 
time as an interval between events. This is a much more interesting story to 
play out in Etoys.

The 12 divisions of a day (and twelve of night) trace back to the need for 
farmers to predict onset of annual rainy season. Rain leads to floods in the 
river depositing rich silt along the banks (and ground water) to raise crops. 
There are approximately 12 full moons between one Rainy season to another and 
approximately 30 sun rises between two full moons. The same divisions were 
also applied to day and night. Some cultures (like India) divided day and 
night into 30 slots each (or 60 slots total) while others divided them into 12 
slots each (24 total) and further into 60 minute slices. Some (like 
Babylonians) divided both day and night into 12 slots. These divisions allowed 
one reckon and predict the onset of rains. The numbers 12, 24, 30, 60 and 360  
became important in math. We continue to divide a circle into 360 degrees 
(12x30) to this day.

The word time itself is from a root word meaning 'to slice, to cut'. The Greek 
word, kairos  means both weather and opportune time. The Sanskrit word for 
year (varsha) also means rain.  Many words in our daily use are tied to this 
concept of time (hour, minute, temporary, noon, meal, siesta, tide).

Of course, 12 moons per year is approximate so an 'extra moon' is added every 
few years to catch up. This year is one of them, so it is a good opportunity 
to learn about  'blue moon'.

No, the BBC video Papert and Talking Turtle shown in five parts. See part 2:

  http://www.youtube.com/watch?v=BTd3N5Oj2jk

Papert [1:37] : The essential point about the turtle is its role as a 
transitional object. That is, transitional between the body, self and the 
abstract mathematical ideas. The turtle, you can identify with it. You can 
move your body in order to guess how you can command the turtle. So it is 
related to you, your body, your movement and it is also related to 
mathematical ideas.

Papert's genius lies in creating an environment in which children can not only 
experience distances, turns and geometrical shapes but also digitize them into 
countable numbers for operating the turtle. Pen trails help children to detect 
and correct any encoding errors. In this process, children use principles of 
differential calculus (countable offsets from current location), integral 
calculus (accumulate counts), arithmetic (modulo operators) and not geometry 
(compass-ruler constructions).

The teacher in the video summarizes it very well:

Teacher [4:13]: The great thing is it provides a mathematical environment for 
the children. While the children are working around the turtle, if you listen 
to what they are talking about, it's all mathematical. Verbalization in 
Mathematics is very important and I think that half of the problems with 
Mathematical teaching is that students don't communicate mathematically, talk 
about mathematics and experience mathematical problems...

The numbers on the clock (and its shape) encode experiences that many adults 
take for granted but which inspire awe in children. Why deny them the wonder 
by jumping into encodings right away?

 Could you outline the issues you have faced while trying out local

This will require a separate thread :-(. But briefly, we faced issues in all 
three aspects - input methods, character encodings and rendering.

Schools use the regular US keyboard for entering vernacular characters. SCIM 
(m17n) was not stable enough when we started. Recent versions are much more 
stable and we are trying them out this year.

Much text work in Kannada is still based on proprietary encodings (Baraha, 
Nudi). Baraha/Nudi were designed for office documents, not school work. 
Transition to Unicode/UTF-8 for text is not yet complete.

Indic truetype fonts don't blend well with text mixing English and Math 
symbols. Kannada scripts involve double subscripts giving them a larger 
average height. Indic text will appear visually smaller in mixed context. You 
will see this effect in mailing lists like Indlinux-group. Fontography is yet

The risk here is one of distraction. Models on computers are no different from

entertains but does not lead to contemplation is no different from a Magic

 The issue of teaching real science depends on awareness. I don't see a

intricate geometric patterns laid on the floor or board by running off rice

way reminiscent of Papert's early experiments with children. Skills are 
acquired by observing, imitating elders and (lots of) practice. Beginners use

Traditional kolams used only pure rice flour as paste or powder (as offerings

The monitors can be used with a long VGA cable and no separate projection

Bangalore for its initiative to improve the quality of public education:

http://citizensalliance.wordpress.com/2010/02/28/good-samaritans-some-of-

One of the key empowerment initiative in Sikshana revolved around using Etoys 
on a memory stick (as a personal soft computer) to get children to express 
their ideas freely unhindered by the fear running out of (precious) supplies 
like paper, pen or paint. The pilot started in a handful of schools in 2007 
and then spread, by popular demand from teachers, to 120 schools today with 
many more waiting in the pipeline. Details are in 
http://sikshana.blogspot.com.

Sikshana is a tiny organization with only 15 employees guiding 250 school and 
30k children. That we were able to scale to this level is because of the 
support of patrons and volunteers across the world.

I wanted to take this opportunity to thank all developers, past and present, 
of Squeak and Etoys and let them know that their work is making a big 
difference in the lives of middle school children in the remote village schools 
in India.

 If you have any ideas for problems I can use and/or suggested lesson

Having helped my daughter deal with algebra last year, I can share my first-
hand experiences of the 'confusion' that kids face with the subject. It starts 
with the name - 'algebra' - sounds like a magical incantation. Most books on 
algebra begin with notations :-(.

Let me digress a bit here. I have often watched kids struggle with divisions 
dealing with zeroes:
___
  3) 6024

If I ask the same kid the following questions (no pen and paper, just head 
math):
 a) How would you split 6000 Rupees equally amongst three friends?
 b) How would you split 24 Rupees amongst the same friends?
 c) How much will each friend get if you distribute both 6000 and 24 Rupees 
amongst the same friends?

Kids who struggle with the former have no trouble answering the latter Qs. 
Once they play this game a few times, they have no trouble solving division 
sums on paper. The rules of the game are understood intuitively. What they see 
on paper is a picture of what they carry in their head. Notation is no longer 
a barrier - 6024, 6000+24, 6000+20+4 are all the same thing in the head.

Back to your question. The origins of algebra lies in the games that kids used 
to play in India with seeds (the subject continues to be known as Seed 
Arithmetic in India). A bag containing different types of seeds constitutes the 
alphabet and arithmetic gives us the rules for composition. Kids get to make 
up different riddles using the alphabet and rules. Algebra is just Arithmetic 
for Fun.

If a pile with 5 red beans and 10 yellow beans cost 20 pies and another pile 
with 20 more yellow beans cost 40 pies, how much does each bean cost?

Advanced riddles make use of bricks, tiles, blocks, or rope lengths instead of 
seeds but the rules remain the same - simple arithmetic. See Julia Nishijima's 
exercise in page 13 of http://www.vpri.org/pdf/rn2007006a_olpc.pdf

After a few such riddles are solved in the head, the 'reduce and balance' 
algorithm is intuitively grasped by kids. Now the notation can be introduced 
without confusion:

   5r+10y = 20, 5r+10y+20y=40

Introducing notation before thinking leads to all kinds of confusion.

using mini-speakers with mp3 player in classrooms. The players, about 4 cube 
take in 2GB USB flash, SD card or micro-SD cards and play for 5 hours on a

four-five years of language lessons. Neither teachers nor 6-9 year olds think

We could also think of using portable mp4 players (for visual lessons) or

True. A Grannie need not necessarily be a grand parent of the learner but a

social diversity. Sugata's high tech props distracts us from seeing the 
facilitative aspects found in the environment. Grannies do three things that 
facilitates the learning process. Firstly, they are there during learning[1], 
Secondly, when a child completes a task, they celebrate the culmination of the 
process regardless of the economic value of the outcome. Thirdly, they guide 
the child to select the next process that is *meaningful* to both the child 
and the *social context*. Such appreciation and mentoring are invaluable in 
helping children learn faster and better.

A centrally planned curriculum applies a linear model of learning over a large 
number of children in different social contexts. It assumes that there is only 
one way for the next level. In practice, a child is faced with lots of choices 
on what to pursue next.

Notice the slip in TED teaser's last statement - results that could

education as a learning process.

 their website doesn't do quite justice on how concepts like this

Thank you for this link. It is good to know of other efforts towards 
educational reforms. MGML is already in place for grades 1-3 in all public 
schools in my state and is being expanded to higher grades every year.

MGML is a problem only in curricular-driven environments. This is how children 
learn, say, in homes or in playground. Grouping happens naturally by level of 
competence and interest rather than by age.

Previous efforts that I tracked did not close the loop. That is, they would 
train teachers and expect changes to happen but did not verify if learning 
actually happened. No method works for every child. That is why Sikshana 
decided to work backwards - ensure every child is able to learn and keep 
learning and support teachers to use their own masala (mix) of methods.

 Hi All...
 Here is a concise article that summarizes Sugata Mitra's work with the
 Granny Cloud.  Note he says a 1 to 1 model doesn't work. He uses 4 to 1.

I would be wary of reaching any specific conclusion from such experiments. This 
is not to discourage new experiments but to highlight the fact the need of the 
hours are interventions that ensures that the number of students who are *not 
learning* should provably *decrease* during a three year window.

When we throw technology X or method Y at the education problem and make the 
top two quartiles learn better but leave the bottom quartile out cold, then 
such a tech/method is a nice but unimportant development for tacking education 
issues we face today.

 hmm, sure..., sorry   What does it mean? 90% of the children get 100%?  
 Is there a sliding scale / bell curve?  what is fluency, anyway?  
 fluency in what?
I can share my experience in helping out Sikshana (www.sikshana.org). Sikshana 
sends out people (mentors) to assist public school teachers to do a dip stick 
check at 4th and 7th in four areas:
 * expression - does he/she speak freely? do he/she open out to teachers and 
peers for help in getting supplies, seek clarifications etc?
If so, check
 * writing - can he/she write down thoughts and needs? Spelling and grammar 
errors are ok as long as the meaning comes through clearly.
 * reading - can he/she read (unseen) sentences, paragraphs, written requests, 
understand and be ready to act upon it?
 * numeracy - can he/she perform division (arithmetic) of three or larger 
digits and verify the result?

These checks take only a few minutes per student and serve to indicate if 
he/she has started learning and build a foundation for life. We do this for 
the primary language in 4th and check bilingual/trilingual skills in 7th. A 
list of students who fall short is drawn up. We don't spend time on analyzing 
why the gap occurred but ensure that each student  is adopted by an adult - 
a teacher who has stepped forward to take up this challenge or a local 
volunteer or a teacher assisted by a local volunteer. 

In a typical cluster of 15 schools (~1500-2000 students) around 25-30% fall 
short even with tech infusion. But with personal attention, the numbers drop 
below 10% in a matter of months. The bar is then raised slowly so that no 
student is left behind. The exact method used to attain fluency is left to the 
teacher.
