Jeenath Rahaman

Research Scholar

Jeenath Rahaman is a doctoral student at HBCSE, working in the field of Mathematics Education and Cognition. Her research interests revolve around students’ understanding of  measurement, multiplicative thinking, proportional reasoning, spatial thinking, geometry and fractions, which she is studying through the lenses of cognition, visualisation, gestures, embodied cognition, physical and practical resources of learning. These research interests have a major impact on her doctoral study, where she is examining students’ understanding of area-measurement through various lenses. Jeenath’s work is attempting to integrate the perspectives from the field of cognitive science to understand students’ learning of the mathematical concepts.

Presently she is analysing students’ data from two perspectives. In the first perspective, she is trying to understand the concept of area as a network of several other subconcepts in maths and how the network components impact students’ learning. While in the other perspective, she is trying to understand the cognitive nuances that might have an effect in students’ understanding of area measurement.

Jeenath is also an active resource person for conducting workshops on learning mathematics through Geogebra for teachers and students.

    K. Subramaniam

    Professor

    My main work for the last decade and a half has been research and development on improving the learning and teaching of school mathematics. I have studied, along with my colleagues, how children can be helped to make the transition from arithmetic to algebra, how they can be supported in learning fractions and multiplicative reasoning, and how out-of-school mathematical knowledge can be related to school learning. I have also worked on developing models for in-service teacher professional development. I have authored text-cum-workbooks and teacher books on mathematics for students of Class 3. I have contributed to formulating education policy through my participation in the focus group on the teaching of mathematics, the syllabus committees for NCF-2005, the curriculum and textbook committees for the state of Maharashtra (since 2011). I am a member of the National Council of Teacher Education (2013-present). I have a B.Tech in Aeronautical engineering and an M.A. and Ph.D. in philosophy. My Ph.D. dissertation was on aspects of the philosophy of history, with a focus on the Continental Philosopher Heidegger. Before joining HBCSE, I taught mechanical engineering at the college level.

          Arindam Bose

          Research Scholar

          Arindam Bose is an advanced doctoral candidate in Mathematics Education. He holds a Master’s degree in Mathematics and five years of teaching experience at the undergraduate level in Patna University, India. During this teaching stint, Arindam’s involvement in the curriculum development of school education as a member of the mathematics focus-group of the Bihar Curriculum Framework 2006 motivated him to move into research in mathematics education.

          For his doctoral dissertation work, Arindam explored the nature and extent of everyday mathematical knowledge possessed by middle grade school students living in an urban low-income settlement that has embedded in it a thriving micro-enterprise economy. The objective of the study was to unpack and document the connections between students’ mathematical knowledge, work practices and identity formation, and inquire into the implications of these connections for school learning. His study argues that experiences from everyday work-contexts makes students familiar with artefacts and practices that represent a crystallised and embodied form of mathematics, which can be resources to make potentially powerful connections with school mathematics. The study further argues that school mathematical knowledge represents a form of generalisation or abstraction consisting of ideas or constructs that illuminates diverse instances in the everyday settings.

          Arindam’s key areas of interest in Mathematics Education are connections-disconnections between out-of-school and school mathematics, language diversity and math learning, and ethnomathematics.
