CUBE Winter Meet

January 21, 2017

After celebrating goof-ups in research on 26 Dec 2016 and a followup
one week workshop, CUBE is organizing its Winter Meet on Sunday 22 Jan
2017, in Auditorium from 10:00 am to 06:00 pm.

There will be approximately 75 colleges students from Mumbai and few
from Delhi, Kerala, Baroda, Guwahati.

The idea is to share their continuous work on model organisms which
they have been working on in their own labs. Students in groups
working collaboratively from different colleges will be making
presentations.

The model organisms are: Snails, Drosophila (fruitfly), Hydra,
Earthworm, Moina/Daphnia (water flea), Pagalapos (Rotifers,
C.elegans), Mosquito, Cardamine (weed/plant).

Each and atleast two model organisms have a reserach question based on
regeneration, epigenetics, diversity, etc.

An added session is on DNA extraction by the jugaad way, i.e. not
using any sophisticated materials but still performing the experiment
using daily available materials. This session will have movies created
by students themselves while doing the DNA extraction.

Nat Geo Explorer Education Program

March 27, 2013

A member of National Geographic Explorer Education Program conducted a presentation at HBCSE a couple of days ago.  As we know the photo, video quality of Nat Geo has always been a visual treat to us. They are now exploring into the education arena with so called state-of-the-art technology.  After the seminar, during the discussion, I made quite a lot of observations and raised some concerns as well. I thought of discussing here also.

I thought, in order to create a direct impact of the life with its environment, the appropriate context needs to be defined. Although the content was encompassing the world’s geography, to me, it does not make sense if I am not aware of the geography, the life, the environment of my own surroundings, and neighbors. I recalled that in our education system, giving Western names were being criticized and it was emphasized to give names that convey about the Indian context. I thought NGX education program is repeating the same old method.

Again talking about the context, the photos of classroom learning, were shots of  Western people. And it was being contrasted with  the lack of facilities in education which were shots of poor, tribal people with ‘look of hope’ photographs.  I did not understand why do they still hold such prejudice.  (On a side note: I recalled the scene in Munnabhai MBBS, where a tourist wants to see India and he mentions that he wants to see the crying people, sad people. To which ‘circuit’ slams him by saying that all you tourist want to portray is a bad picture of India, don’t you ever see good things of India like, Taj Mahal, etc.).

My concern, was that since the program is packaged with a subscription which can also allow online content, seems to cater to elite schools in India. But the country has a huge number of govt. schools, where there are huge number of first generation learners, let alone English speaking learners, I doubt how the program could cater to such situations. The program seems to be compliant with the smartboard method of teaching. But it does not cater to a traditional chalk and talk classroom teaching which is still being practiced in many schools in the country.

Access to teacher’s handbook is mandatory, but this is possible only after subscribing with a fee. That leaves with no option for a teacher to explore the content. I also could not get a satisfactory answer when I asked whether the content was in public domain.

The presenter made a remark, that NGX education provides knowledge, and quoted KBC’s promo ‘Gyaan hi Sabkuch hai’. To me, this kinda knowledge presented is fact-based knowledge. From the presentation, there was no hint that learning can be activity based. The program is a visual treat of photos, videos, simulations, with text. However it lacks activities. When I raised this issue, the presenter mentioned that there are activities, but it needs to be done under the supervision of teachers.  Above all the presenter also asked whether the Indian textbook provides scope for activities. Immediately I clarified that the science textbooks in the country are activity based which is a direct influence of the policy document NCF 2005.

Anyways, I am still skeptical that such a program could provide support to science learning in the country’s govt. schools, given that a large number of learners are first generation learners, native language speakers, uses traditional chalk and talk method of teaching. Let me further state, that even with such situations, I think, we are certainly doing quite well.


Janabai

March 7, 2013

I have been reflecting on the NCF 2005 — Teaching of Science Focus Group Position Paper. I am reading it for conducting a session for the DIET teacher educators in Bihar. I particularly would like to reflect on the ‘Janabai’ point. Below is the verbatim text from the document (p. 12), some critical questions that I raise, and some discussion around it.

What Biology do students know?
“These students don’t understand science … they come from a deprived background!” We frequently hear such  opinions expressed about children from rural or tribal backgrounds. Yet consider what these children know from everyday experience: Janabai lives in a small hamlet in the Sahyadri hills. She helps her parents in their seasonal work of rice and tuar farming. She sometimes accompanies her brother in taking the goats to graze in the bush. She has helped bring up her younger sister. Nowadays she walks 8 km every day to attend the nearest secondary school. Janabai maintains intimate links with her natural environment. She has used different plants as sources of food,  medicines, fuel wood, dyes and building materials; she has observed parts of different plants used for household purpose, in religious rituals and in celebrating festivals. She recognizes minute differences between trees, and notices seasonal changes based on shape, size, distribution of leaves and flowers, smells and textures. She can identify about a hundred different types of plants around her, many times more than her biology teacher can – the same teacher who believes Janabai is a poor student. Can we help Janabai translate her rich understanding into formal concepts of biology? Can we convince her that school biology is not about some abstract world coded in  long texts and difficult language: it is about the farm she works on, the animals she knows and takes care of, the woods that she walks through every day? Only then will Janabai truly learn science. (NCF 2005 — Teaching of  Science, p. 12).

When reading it critically, I framed the following questions:

  • From whose perspective is this narrative written? — As this is a policy document, we are aware that this is from a teacher’s or the school education’s perspective.
  • What is the nature of knowledge that Janabai has, Is it knowledge or information? –Janabai knows quite a lot of the flora and fauna around here, as she has dwelled in the natural context. But at this stage, I think, that this is mere information. At the point, when she makes association with seasonal changes, etc. then she is constructing knowledge.
  • Why is Janabai’s knowledge different from formal or school knowledge? — If Janabai can recognize the plant by size, shape, etc. (attribution, variable properties of object), I think, Janabai already has scientific knowledge.
  • What are the different classification systems followed by Janabai and teacher?
  • Why is the need for shifting Janabai towards school knowledge, and why not the other way? —
  • What are the different associated knowledge or information that Janabai has?
  • Does this association appear in school knowledge?
  • What is the age of Janabai? — The context is middle school. But if we consider that she is just entering to school, then she may be a teenager, much older than her peers in school
  • The text “She recognizes minute differences between trees, and notices seasonal changes based on shape, size, distribution of leaves and flowers, smells and textures” — This is scientific knowledge that Janabai has?
  • What is this formal concepts of biology?
  • Why is the need for Janabai to learn to understand this formal knowledge?
  • If the school knowledge talks about Janabai’s context “it is about the farm she works on, the animals she knows and takes care of, the woods that she walks through every day”, then why is the impression that Janabai is lacking formal knowledge?

representing change using concept maps

January 28, 2013

While concept maps have been quite extensively used to represent static descriptions, it has not been used  for its full potential for representing changes or processes. We propose a template and a limited set of linking phrases for representing change, with partial amendments in the concept mapping technique and the CmapTools. Usually, a process is represented in a object-centric manner specifying the object’s role init. In this proposal, we suggest a process-centric strategy with certain heuristics for  representing  processes. Considering the view that a process is a name to a change of state of an object involving time, sequence, causes, we make necessary proposals to the vocabulary and the form of representing a process.We end with a discussion on implications of this proposal to science education and concept mapping in general.

mtv roadies audition

February 11, 2011

the season 8 of the mtv roadies – shortcut to hell auditions are on air. its a must watch, especially raghu is very sharp in understanding the correct intentions of the candidates. he can at once know whether the candidate is genuinely interested to become a roadie, or in some cases coming for just time pass, or just to get a chance to abuse raghu, etc.

also interesting to note is the personalities of candidates. at this age of around 20 years, people still are not clear with their lives, they don’t even know what they are upto. more often they are one personality within and want to appear as someone very hard, daring and ready for anything, so on.   raghu even does a good job of counseling  them although harshly.

except for the abusive languages that go on, the auditions are a must watch. the tasks would be same as that of any other action based reality show.
