This document summarizes the presentation "ISS Sindelfingen Towards a dual language programme" given by Sarah Kupke. The presentation outlines the International School of Stuttgart's vision for developing a dual language program. It discusses identifying the learning challenges they wanted to address, such as language equity and international-mindedness. Their idea was to support conceptual and language development through team teaching in both languages. The practice involved implementing a 90/10 to 50/50 model with assessing and monitoring student progress. They developed an additional language learning continuum for evaluation. Reflection on the program evaluated its flexibility and characteristics of effective dual language teachers. The goal was to research best supporting students' language needs.
