An Analysis of Graphs in School Textbooks
Amit Dhakulkar and Nagarjuna G.
In S. Chunawala and M. Kharatmal (Eds.)
Proceedings of epiSTEME 4 International Conference to Review Research on Science, Technology and Mathematics Education,
p. 127-131. India: Macmillan. (2011).
Abstract:
In this study the sample of textbooks that was considered
for the analysis are the NCERT textbooks (from Grade 5 to Grade 10, in
the subjects of Science, Mathematics and Social Sciences). The results
of the quantitative analysis on the frequency of occurrence, types and
features of the graphs present in the textbooks were presented.
Epicyclical Astronomy: A Case for Geogebra
Amit Dhakulkar and Nagarjuna G.
In S. Chunawala and M. Kharatmal (Eds.)
Proceedings of epiSTEME 4 International Conference to Review Research on Science, Technology and Mathematics Education,
p. 324-328. India: Macmillan. (2011).
Abstract:
Epicycles were historically used by the ancient Greeks to
explain the retrograde motion of planets. This episode in history of
science is used as a case to show how we can use computer simulations
to visualize complex, abstract ideas and difficult to imagine
constructions. We present here a method developed using the dynamic
mathematics software GeoGebra, to teach the concept of epicycles.

Mathematical Literacy And Situated Social Knowledge: Understanding Revolving Credit Situated Social Knowledge
Amit Dhakulkar, K. Subramaniam
Proceedings of 31st Indian Social Science Congress
Abstract:
In this paper we explore idea of mathematical literacy and situated social knowledge,
with a case study of revolving credit. First we discuss the broad meaning of the term
mathematical literacy and situated social knowledge. We then turn our focus to the operations
of credit cards and the pitfalls involved for the users. We consider the question of what relevant
mathematical literacy is needed for people to have an understanding of the matters involved.

Radio emission and the optical isophotal twist of radio-loud ellipticals
Gopal-Krishna, Amit R. Dhakulkar, Paul J. Wiita, Samir Dhurde
Astronomy and Astrophysics 410 (2003) 139
Abstract:
Using the surface photometric analysis data for a well defined sample of 79 nearby radio galaxies (z < 0.12), it is shown that the level of radio emission associated with an elliptical galaxy during the radio-loud phase is related to the presence of large amounts of isophotal twist in its optical image. In particular, radio galaxies with P_408 > 3 x 10^{25} W/Hz appear to show a preference to be associated with elliptical hosts exhibiting an isophotal twist in excess of ~20 degrees.
