Gloriana González is a Professor at the University of Illinois Urbana-Champaign. She studies mathematics classrooms with a particular focus on implementations of problem-based instruction through lesson study. Her current work supported by a National Science Foundation grant with Saad Shehab engages geometry teachers in lesson study for them to teach lessons using a human-centered design approach. Her experience implementing lesson study with pre-service and in-service teachers have prompted her enthusiasm for learning more about how this strategy can be used widely. The Lesson Study SIG community is a wonderful place to share this enthusiasm about lesson study!!

Trena Wilkerson is Professor of Mathematics Education and Department Chair in the Department of Curriculum and Instruction in the School of Education at Baylor University. She served on the National Council of Teachers of Mathematics (NCTM) Board of Directors from 2014 to 2017 and as President of NCTM from 2020-2022, along with various professional leadership roles, such as with the Association of Mathematics Teacher Educators, the School Science and Mathematics Association, and state mathematics education organizations. She has also served in leadership roles in the AERA Lesson Study SIG being one of its founding members. She teaches both graduate and undergraduate mathematics education courses, mentors doctoral students, conducts professional development for PK-12 teachers and engages in research in the teaching and learning of mathematics with a particular focus on Lesson Study. Her Lesson Study work has been with both preservice and Inservice teachers along with engaging with mathematics teacher educators. She finds Lesson Study to be a powerful way to engage impact teaching and learning mathematics, especially her own! She has authored or co-authored numerous articles and book chapters has been a speaker for numerous state, national, and international mathematics education conferences and meetings. She has received several state and national awards for teaching, research, and leadership with the most recent, the 2024 Louise Hay Award for Contributions to Mathematics Education from the Association for Women in Mathematics. Excited to work together with our Lesson Study SIG community!

 

Assistant Program Chair - Miriam Vock

BO_08209

Miriam Vock is a psychologist and full professor of Empirical Teaching and Intervention Research at the University of Potsdam, Germany, where she has worked since 2011, training future secondary school teachers in pedagogy and didactics. Her research centers on teacher collaboration, lesson study, gifted and talented students, and inclusive education. She has led several large-scale research projects in these areas, including Germany's most comprehensive lesson study project to date, launched in 2018. In the project’s first phase, 20 schools nationwide together with the team of researchers co-constructed materials and procedures for implementing Lesson Study in Germany. In the second phase, Lesson Study is now being transferred to many other schools in the country via school networks. This state-funded initiative has led to numerous publications by Miriam and her team. She is particularly interested in how lesson study can be implemented sustainably in schools and how the effects of lesson study on learners and teachers, but also on school culture, can be validly measured and made visible. The Lesson Study SIG is a great community for sharing and discussing Lesson Study research!

Ariane Faria dos Santos

Ariane is a doctor candidate in Curriculum Studies at the University of British Columbia (Canada). Her research interests include math classroom practice to improve opportunities to learn for students with different backgrounds. During my Ph.D. program, she is particularly interested in understanding how teachers participating in a Learning Study design lessons to develop numeracy skills in their students as well as how Variation Theory can support teachers in improving what they notice in their classroom. She hopes her research can better connect both micro (classroom/schools) and macro (policymakers) actors to design and implement more equitable curriculum policies.
 
Before her journey in Canada, she analyzed math classroom teaching practices to improve student learning opportunities in Latin America and worked with universities and policymakers to design better curricula and more equitable policies. She is also a former philosophy public high school teacher and math educator in an NGO in Brazil. She holds a master's in International Education Policy Analysis from Stanford University (USA) and another in Education from the University of Sao Paulo (Brazil). She also has a bachelor’s and Teacher Credential in Philosophy from the University of Sao Paulo (Brazil).
