My name is Silvija and I am a Professor for Chemistry Education. Being a student with a migration background, I experienced what it means to be in a class, being motivated and interested but not being able to express yourself and participate in the discussions. It frustrated me a lot of the time. Starting from my biography, my motivation for the topic of linguistic heterogeneity in chemistry classes is even higher. Over the years I focused on research on students, teachers, and the parents and am focusing on developing materials for language-sensitive and language-supportive teaching and learning of science, supporting pre- and in-service science teachers in their competences to teach language-sensitive and language-supportive, and offering parents opportunities to support their children in the development of the language of science.
