The Teacher Education Study in Mathematics (TEDS-M) International Database includes data for all questionnaires administered as part of the TEDS-M study. These consisted of questionnaires administered to future teachers, educators, and institutions with teacher preparation programs. This supplement contains the international version of the TEDS-M questionnaires in the following three sections: Section 1: Institutional Program Questionnaire; Section 2: Educator Questionnaire; and Section 3: Future Teacher Questionnaire (Parts A, B, and D). Each section contains the international version of the questionnaire with variable names labeled next to the corresponding question. The TEDS-M questionnaires were designed so that individual countries could make modifications to some questions or response options. This allowed countries to include appropriate wording or options most consistent with their own national systems, languages, and cultures. In the international version of the questionnaires, questions that needed such an adaptation contain instructions to the National Research Coordinators (NRC) to substitute the appropriate wording for their country or to modify or delete any inappropriate questions or options. Questionnaire items were received from several sources, including study investigators, national research coordinators, and mathematics consultants. Several items were also provided by other studies. The instruments and assessments developed by TEDS-M were the result of the collaborative efforts of the international centers at Michigan State University and the Australian Council for Educational Research.
