Marta Civil is a University Distinguished Outreach Professor and the Roy F. Graesser Chair in the Department of Mathematics at The University of Arizona. Her research looks at cultural, social, and language aspects in the teaching and learning of mathematics; connections between in-school and out-of-school mathematics; parental engagement in mathematics; and participation in the mathematics classroom at the school and college levels. She has led multiple funded projects working with children, parents, and teachers.
Her work is grounded on the concepts of funds of knowledge and parents as intellectual resources. Her most recent work is a collaborative project with two other universities focused on the development of a mathematical partnership that engaged teachers, parents, and multilingual children in grades 2-5 (ages 7-10) in underserved communities. She received the NCTM Lifetime Achievement Award in 2021 and the AERA SIG RME Distinguished Scholar Award in 2025; she became an AERA Fellow in 2023 and a member of the National Academy of Education in 2025.

Prof. Nuria Planas is a professor of mathematics education at Autonomous University of Barcelona (Catalonia, Spain) and Honorary Research Fellow at University of Oxford (England, UK). Before her positions at the university level, she used to be a secondary-school teacher of mathematics. Since then and for almost three decades now, she has been involved in sociocultural research on issues of mathematics education, language and language diversity in urban contexts of poverty. These last years, she has been focused on collaborations with secondary-school teachers of mathematics who work in bilingual and multilingual classrooms, and the ways in which they use language in their teaching with learners whose home languages are not the official language of instruction.
Prof. Dr. Susanne Prediger is full professor in Mathematics Education Research at TU Dortmund University and leader of the German Center for Mathematics Teacher Education at the IPN Leibniz Institute for Science and Mathematics Education in Berlin/Kiel.
She is former editor-in chief of Educational Studies in Mathematics and former president of the European Society for Research in Mathematics Education. She has written more than 120 papers in peer reviewed journals and supervised 28 PhD theses, many of them in the field of language-responsive mathematics teaching. With topic-specific design research and intervention studies, her research group has substantially contributed to unpack the role of language for developing conceptual understanding in mathematics and to show that enhancing students’ language can be effective for students’ mathematical learning gains.
Rama Kant Agnihotri’s thinking, as reflected in his writings about Multilinguality, and in his interactions with educationists here and abroad, shows a depth of understanding about the linguistic dimensions of human communication. This permeates his scholarship as recorded in his many books and publications, and leads to practical applications, in consonance with Constitutional values, in language teaching and learning, in primary education, and in teacher training. He graduated with Mathematics and Sanskrit and did his Masters in English. He got his D Phil in linguistics from the University of York (UK). He has lectured in several universities across the globe. In India, he has been advisor to CBSE, NCERT, SCERT, and DIETs as well as to several NGOs involved in education for social change. Some of his recent publications include:
Being and Becoming Multilingual: Some Narratives (Orient BlackSwan, Delhi, 2022 with Rajesh Sachdeva), Language, Mind and Society (Orient BlackSwan, Delhi, 2022 with Rajesh Kumar), Education and Inequality: Historical and Contemporary Trajectories (with Vikas Gupta and Minati Panda, Orient BlackSwan, New Delhi, 2021), Indian Languages and the Constitution (Eklavya, Bhopal, 2021), Indian English: Towards a New Paradigm (with R Singh, Orient BlackSwan, Delhi, 2012), Hindi: An Essential Grammar (Routledge, London, 2007, 2nd ed. 2022), Noam Chomsky: The Architecture of Language (Oxford, Delhi, 2001 with N. Mukherjee and B. N. Patnaik), Hindi Morphology: A Word-based Description (Motilal Banarsidass, Delhi, 1997 with Rajendra Singh), Second Language Acquisition: Socio-cultural and Linguistic Aspects of English in India (Sage, Delhi, 1994, ed. with A.L. Khanna), Problematizing English in India (Sage, Delhi, 1997, with A.L. Khanna). Having retired as Professor and Head, Dept of Linguistics at the University of Delhi, he is at present Professor Emeritus at Vidya Bhawan Society, Udaipur.

Aldo Parra is an assistant professor at Universidad del Cauca, Colombia. He conducts research on ethnomathematics and mathematics teacher education in contexts of cultural and linguistic diversity. This work demands the use of ethnographic methods and cultural theories to investigate issues like cultural identity, subjectivity, and development. The quest for research methods more communitarian, participative and grass-rooted is characteristic of his work. Aligned to that, he is interested in decolonial studies, alternative philosophies for mathematics. Aldo is trying to develop theoretical concepts for a non-instrumental teacher education in mathematics with preservice and in-service mathematics teacher education. Currently, he is the editor-in-chief of the Latin American Journal of Ethnomathematics
