introducing rigor in concept maps

August 9, 2010

i have been working in the area of refined concept maps for science education. so far we have communicated our research in conferences on science education, concept mapping, etc.

recently, our work got published in Springer’s LNAI  book.  the paper ‘introducing rigor in concept maps’ was presented in the 18th international conference on conceptual structures 2010 at kuching, malaysia. the paper talks about applying rigor by focusing on relation names, the re-representation of sentences to propositions in RDF triples format, and how the refined concept mapping methodology can act as a bridge between informal and formal models of knowledge bases.

the epiSTEME 4 poster and brochure are ready and uploaded on the conference website:

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.

SELF-Platform—A Teacher-Centric Collaborative Authoring System

May 25, 2009

HBCSE – Gnowledge Lab has developed the SELF Platform as part of the European Commission funded SELF Project # 034595 (2006-2008). A paper on SELF Platform as a teacher centric collaborative authoring system has been published at the NCOSS conference organized by CDAC, Kharghar, Navi Mumbai, May 2009.

The SELF Platform caters to a teacher to create learning materials.

The full paper is available from the publications page of my blog.

focus group meeting

January 9, 2009

During the episteme3, our presentations on Refined Concept Maps, generated interest among few participants. A focus group meeting for more interaction, collaboration was planned after today’s lunch. The members included Dr. Vrunda Prabhu, Dr. Brian, Prof. H.C.Pradhan, Dr. Nagarjuna, Ms. Meena. The group from City University, New York have  a repository of concept maps on mathematics based on their research work, students’ essays, etc. Prof. Pradhan shared his research on concept maps on physics and ways to analyze the concepts based on the links, distance. Our research group (Nagarjuna and Meena) shared our  research work on refined concept maps on biology  domain, and how the can help build a  roadmap of knowledge from any given domain. The group also discussed on how to use the cognitive distance, semantic proximity for analyzing the concepts in a network.

This seems a useful outcome of the episteme-3 conference for our research group. Let us see how it proceeds.

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.

Hmm. While i am writing this post, our paper on Exploring the roots of rigor is being presented in the CMC2008 conference at Tallinn and Helsinki. I am not physically attending the conference. But I am doing the best I can do by sitting in my office here in Mumbai, India. Since the time the detailed program was announced, I have been going through the papers which might be of my interest and relevant to my research work. I am interacting with those researchers and informing them to attend our session on thursday. Even before the conference began, I have been already getting emails from researchers and our discussions have begun. Some are keen to continue the discussion after the conference, as they are busy in this conference week. That is really a good sign and a good outcome of the conference.

Hmm so I am virtually in the conference 🙂
