Elma Blom

Head Project Leader

Elma is a Language Development and Multilingualism Professor in Family and Education at Utrecht University. Her background is in Dutch language and literature, specialising in formal linguistics and sociolinguistics. During her PhD and doctoral training, she focused on (a)typical language development and children growing up in a multilingual environment. As the project leader, Elma keeps an overview of the project, the consortium, and the outcomes of Multi-STEM. Additionally, she co-supervises all three PhD students on the project. We know that multilingualism can create barriers. What she would like to achieve with Multi-STEM is that, instead, multilingual practices enrich the interaction, learning, and teaching experiences of children, families, and educational professionals. 

Jantien Smit

Subproject Leader

Jantien is a lecturer in the Multilingualism and Education research group at the Hogeschool Utrecht (HU). She obtained her doctorate in 2013 for her dissertation, “Scaffolding language in multilingual mathematics classrooms.” Her research focuses on multilingualism in primary education, language-oriented math and science education, scaffolding of language, and teacher professionalization. Jantien is the project leader for Multi-STEM subprojects “School” and “Science Museums.”  

Arthur Bakker

Subproject Leader

Arthur is an Associate Professor of Mathematics and Science Education at Utrecht University. He has a background in mathematics and worked as a math teacher in secondary education. In addition to STEM education, his research interests include boundary crossing, scaffolding, and design research. Arthur is the leader of the subproject ‘Boundary Crossing’ which is conducted by the postdoctoral researcher. This subproject aims to conceptualize translanguaging as boundary work and to develop a methodological approach for studying translanguaging across the contexts of home, school, and museums. They intend to develop a rich and nuanced conceptualization of translanguaging practices and establish an empirical basis for making decisions on how to stimulate multilingual practices. 

Eva van de Weijer

Subproject Leader

As a researcher at Utrecht University, Eva’s work focuses on the role of parents and teachers in child cognitive development and mathematical learning. She is the project leader for the “Home” subproject. She thinks along about how to involve parents, which theoretical frameworks are relevant, which factors are relevant for translanguaging strategies and mathematical learning, as well as study design. She hopes to contribute to a stronger sense of belonging and mathematical learning in multilingual children, by allowing them to access their (math) knowledge in these languages more readily.   

Gerald van Dijk

Subproject Leader

Gerald is a teacher educator and researcher in the Curriculum Development in Primary and Secondary Education research group at the University of Applied Sciences Utrecht. In his PhD research, he developed a training for science and technology teachers to become more language sensitive. Gerald is the leader of the subproject ‘International’ which involves international collaboration with both the University of Malmö and Lund University in Sweden. For decades, the Swedish society and educational system have had a positive climate concerning multilingualism. In Sweden, they foster multilingual development and translanguaging in education. Through this collaboration, Multi-STEM expects to identify fruitful conditions for the use of multilingual resources in education.

Ronald Keijzer

Subproject Leader

Ronald studied mathematics, worked as a primary school mathematics teacher, and did his PhD on fraction learning at the Ronald is a Professor of Applied Sciences in Mathematics Education at the IPABO University of Applied Sciences in Amsterdam. He has a master’s degree in mathematics and a PhD in mathematics education. Ronald worked for 34 years as a teacher educator in primary education. His present activities focus on professionalizing primary school teachers in mathematics education and collaboration in professional learning communities.  Ronald is the leader for the subproject ‘Towards Societal Change’ working together with the project coordinator Shaunna Calpin to identify how Multi-STEM’s outcomes can be shared with teachers, other education professionals, and parents. In Multi-STEM he would like to facilitate collaboration and information exchange between science centres, family associations, education professionals, and parents. 

Mirona Moraru

Postdoctoral Researcher

Mirona has explored the relationship between language and migration both in her PhD in Language and Translation Studies (Cardiff, UK), as well as during her experience in the field of Foreign Language Teacher Training (Chile). Mirona’s postdoctoral research (subproject ‘Boundary Crossing’) aims to develop an overarching conceptual framework for translanguaging as a form of boundary crossing. Her work builds on insights from the three PhD projects in order to explore the mechanisms involved in children’s participation across different learning contexts. Mirona hopes to contribute to a better understanding of the affordances of translanguaging in different learning settings.  

Erin Gail MacDonald

PhD Researcher

Erin Gail MacDonald has a background in sociology and a master’s degree in Urban Sociology. She has worked in math education for almost a decade and finds that math can be a wonderful outlet for creativity and connection. Her PhD (subproject ‘Home’) aims to develop tools for caregivers of multilingual children so that they can be involved in their children’s education in a way that is meaningful, accessible, and fun. She hopes that multilingual children will be able to participate more holistically in math education by using all of their linguistic resources and knowledge reserves.  

Lianne Stolte

PhD Researcher

Lianne has a background in linguistics and a general interest in inclusive education. Her PhD (subproject ‘School’) studies how multilingual children can benefit from learning in their home language. Together with a team of both researchers and practitioners, she will develop, implement, and evaluates multilingual strategies for teachers and their students in primary education. One of her aims is to find out how to support teachers in developing certain multilingual practices. Close collaboration with practice is a fundamental element of her research. 

Lucía Chisari

PhD Researcher

Lucia came to the Netherlands from Argentina in 2017 to follow a After her studies in biological sciences, Lucía went on to work and do research in science education. She came to the Netherlands from Argentina in 2017 to follow a master’s in Educational Sciences. Her PhD (subproject ‘Science Museums’) aims to develop translanguaging strategies that promote the participation of multilingual children with migrant backgrounds (and their families) in science museums. In Multi-STEM, she hopes to learn more about what the challenges and opportunities are for science museums to use multilingual children’s home languages.  

Zahraa Attar


Zahraa is fascinated by languages and their relation to learning. She has a background in linguistics [with a focus on…] Her research (subproject ‘Child’) looks at ways to incorporate children’s voices about multilingual strategies both at home and at school. An important motto in her project is “nothing about us without us.” Together with the children, she looks for opportunities to facilitate their learning by using their home language. Empowering the children is essential for achieving her goals.  

Shaunna Calpin

Project Coordinator

Shaunna has a background in Global Affairs & Religion with a focus on public issues. She has worked in the public sector for 5 years and her interests include efforts to facilitate the inclusion of people with a migration background, low literacy, and other minority groups. As the project coordinator, Shaunna is responsible for the consortium and its 31 partners. She’s a sparring partner for the MT/PhDs and supports the leadership team by keeping an overview/ assisting the different timelines and deliverables in the project. Furthermore, she works together with Ronald on the subproject ‘Towards Societal Change’ to identify how Multi-STEM’s outcomes can be shared with stakeholders. Through Multi-STEM she hopes to contribute to multilingual children (with migration backgrounds) feeling seen and heard at school.
