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.
