a primer for constructing and analyzing conceptual structures

May 20, 2011

Refined concept mapping, a development over the regular concept mapping is an approach towards introducing rigor and parsimony in representing knowledge. The method proposed suggests substitution of the ambiguous relation names with well-defined relation names to concepts consistently while mapping a domain. We suggest the use of
this method for introducing rigor in concept mapping and position it among other models of knowledge representation in an inverse semantic spectrum. This paper was presented at the 18th ICCS 2010 conference.

Now in continuation, we have proposed to develop a primer (guide, tutorial) that can be used to apply RCM as a methodology for representing knowledge. This has been accepted at the CSLTA 2011 workshop to be held in conjunction with the 19th ICCS 2011 conference.

In this paper, a rationale and proposal for developing a primer for teaching-learning of conceptual structures is presented. The skills required and developed by an engagement of constructing and analyzing conceptual structures are richer and easier to be dealt with in school education. The teaching-learning context of CS is fundamental and important enough to introduce the topics from logic, philosophy, computer science and linguistics. A proposal is made for the formation of a special interest group for the primer. More about the paper.

The framework of the primer comprises of Units (lesson plans) with specific Learning Objectives. We suggest that the primer can serve as a guide to areas such as knowledge representation, conceptual structures, etc.


citations to our work on refined concept mapping

being a phd student and getting to know that my research work is being cited by peers is good news!

google scholar shows it all.

cheers to peers!

check out papers on refined concept mapping from the publications page of my blog.


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.

conceptual change and learning

March 15, 2009

As part of my Ph.D. work, I am reviewing various models of learning, conceptual change for learning. I am planning to review the works of Piaget, Carey, Thagard, Nersessian, Keil, Chi, Vosniadou, Ausubel, etc. and trying to characterize their models of learning.

I shall post the review, once an initial draft is ready.


visit to somaiya college for depmap workshop

February 25, 2009

Today I planned a visit to K.J.Somaiya college of science, vidyavihar with regard to plan for organizing depmap workshop for teachers. I met the faculty from physics, chemistry, biology, botany, microbiology, education departments of junior as well as senior college.

I explained about the objectives of the depmap workshop and since it is to build a teaching sequence, it would be useful if teachers themselves create their dependency maps using the web based portal in the hands-on workshop to be conducted in gnowledge lab, hbcse.  Teacher have got a fair understanding as I also showed them some featured maps picked out from the portal.

Overall, all the teachers whom i met are interested to participate in the depmap workshop. Teachers from each department will be participating in the workshop in april, may, june.

Initially the visit was planned for about an hour, but my visit got extended for more than 2 hours. Actually I have studied for H.S.C., B.Sc. & M.Sc. from Somaiya college. When i was meeting the teachers, i too got nostalgic and to my surprise, most of the teachers could remember me as their student. So my visit got extended as I met my teachers in the corridor, labs, and was talking about my work and research. A few teachers also were keen to know about my Ph.D. work in the area of biology education. My teachers were glad to know about my progress, i being an alumni of somaiya.

I was thrilled to go back to my college, to my teachers and convey my contribution to science education.


depmap on activity—who got the food

February 2, 2009

i was mapping the topic who got the food from chapter 4- looking at
animals from the small science curriculum for class III. and this is
the route that i followed to map.

depmap on food eating habits

depmap on food eating habits

an interesting depmap to build a thread as :
inorder to understand the concept of animals, one need to first
observe some animals, their food eating habits. the latter can be
understood in the context of an activity. once these activities are
performed one can categorize and classify which animals eat what kind
of food and then may be understand the concept of a dog, cat, and then progressively the concept of an animal.

Small Science Curriculum is an activity based curriculum developed by
HBCSE. It focusses on teaching science through activities.
