my presentation at the annual research meet

February 18, 2010

as part of annual research meet in HBCSE, I presented the current work of my ph.d.  It was mainly focussing on “to determine a fixed set of relation names to represent secondary school level cell biology”. The abstract can be read from here.  there were useful inputs and comments on the work.

the presentation depicted the number of concepts at 8,9,11 standards and the number of relation names required to link these concepts.

both print version and web version are ready for circulation.

just to add that both the poster and brochure have been designed using inkscape by me and sugra.

promising strands for future episteme conferences

January 9, 2009

Today, on the last day of the episteme-3 conference, we had a round table discussion on two issues: promising strands for episteme conferences; to build a community  of STME research in India. I was involved in the first round table. We reviewed the last episteme -1, episteme-2, and the current epistme-3 for the strands (or themes) of the conferences, and the outcomes. The main strands that episteme conferences will always be based on are: History and philsophy of science: its implications for science education; Cognitive basis of learning, pedagogy and curricular issues. From the discussion, atleast four strands have emerged which the participants are interested in the future epistemes. These have been: classroom based practices; affective factors in learning, science technology studies issues, integrating STME, assessment (to bring into focus), universalization of education.

The other topic also got a good involvement from the participants to building a community for science, technology, and mathematics education in India. Some of the suggestions are: to build research standards, develop knowledge portals, create summer programs, evaluate projects with collaborators, engaging with scientific institutes, universities, etc. etc.

These two topics of the round table discussion would enable us to concretize the strands of our future episteme conferences of HBCSE.

Our research study on Refined Concept Maps for Science Education: A Feasibility Study got presented today in the Episteme-3 conference in HBCSE, Mumbai, India. The main highlights of the paper presentation have been on demonstrating the students’ ease of using the refined concept maps i.e. to apply a minimal set of relation names (linking words), without any loss of knowledge. The RCM method was compared with other two methods: description and traditional concept maps. We applied ANOVA and T-Test for statistical analysis. The study indicated an increase in the number of correct relations for the domain of nucleus and mitochondria. The relation names served as facilitator or an anchoring device for representing knowledge.

Episteme 3 is part of Episteme series of biennial conferences that is organized by HBCSE.

Khoj 2008 – Gurgaon

October 6, 2008

Like last year, I was invited to be a judge for the International School Competition on Science Projects in DAV Public School at Gurgaon. The projects dealt on issues of Global warming, Future Energy Sources, IT, Clean and Green City, etc. Overall the students were very enthusiastic about their models but when it came to conceptual understanding the students were found to be not so competent.

Later on the second day, I was one of the panel members for the discussion on the topic of Science Education – A Challenge. This was held for the teachers. The other members of the panel were from IITD, NCL, BARC. The panel discussed on how the teachers can help the students to generate an interest towards science, about classroom learning, conceptual understanding, relating their learning with their daily experiences, etc.

Workshop on collaborative building of online e-learning courses @ HBCSE

June 10, 2008

Announcing a workshop on
“Collaborative building of online e-learning courses”

June 25, 26, 27, 2008
Gnowledge Lab, HBCSE

The Gnowledge Lab (computer lab) of HBCSE has developed a
web-based e-learning platform for creating courses. The platform is
mainly focused on authors, content generators, translators,
instructors who wants to create course materials for dissemination of
knowledge. A glimpse of a few prototype course materials that are
being developed can be viewed from
The Gnowledge Lab is pleased to announce a workshop on Collaborative
building of online e-learning courses using SELF Platform, in all
languages particularly in english, marathi, or hindi.

We invite all of the staff members from HBCSE—academic, scientific,
research scholars, project, administration, technical—to participate
in this workshop.

Features of the workshop:

* Creating on-line courses in any subject using any language
* Adding & organizing lessons, glossary, faqs, test questions
* Creating personal bookshelf
* Inserting images using filemanager
* Exchanging course materials using import and export modules
* Creating versions of courses and comparing changes
* Using electronic conference room for online collaboration of courses
* The participants who will be developing content will be credited as
authors of courses automatically by the system
* The content developed will be published under GNU-FDL licence
(same as wikipedia license)

Our team will provide a demonstration on using the SELF Platform. A
training on how to type in Indian languages and publish on the
Internet will also be provided as part of the workshop.


Interested participants can register for the workshop by sending an
email to —– self [at] —— before 20th June. The
number of participants is limited upto about 10 participants on each
day. The same workshop will be repeated on each day. So please specify
the date on which you would like to join the workshop in your email
registration. After the one day workshop you can continue to build the
courses from anywhere and collaborate using the electronic conference

Venue: Gnowledge Lab ( Computer Lab – 108 )

Timings: 10:00 to 17:00

Tentative Schedule:

10:00 – 10:30 Introduction to the Gnowledge Portal & SELF Platform

10:30 – 10: 45 Quick demonstration on building on-line courses

10:45 — 11:00 Tea break (Tea and Snacks will be provided)

11:00 — 13:00 Hands-on session on building courses

13:00 — 14:00 Lunch break

14:00 — 16:00 Hands-on session on building courses

Concept maps for eliciting students’ knowledge of science

December 14, 2007

I presented a poster on the above title at the National Conference on Science Education here in Mumbai on December 13, 2007. The objective of the study was to prove the feasibility of concepts maps for eliciting knowledge of science at the seconday school level. Two homogenous groups were considered for the study. Of these one group was assigned a task to describe the domain of the structure and function of nucleus and mitochondria and the other group was assigned  a task to draw concept maps on the same domain. The analysis was based on the total number of concepts and total number of scientifically valid releations (sentences) in both the modes of representation. The average showed that there was no significant difference which means that even though with concept mapping as a new technique the knowledge structure was similar in both the modes and there was no loss of knowledge. An interesting observation that came out of the study was that in the description mode there were quite a number of misconceptions, incorrect relations, idio-syncratic, non-scientific way of representation. On the contrary, since the concept map model has a structure and constraint, it does not give any scope to  such idiosyncratic or non-scientific mode of representation. With this model it is possible that students can represent their knowledge which can be quite close to an expert’s representation. The concept mapping technique was found to be feasible with the students for representing scientific knowledge.
