The TOP Alumni Lesson series from 2025 is designed for elementary to high school educators of socials studies and STEM subjects with comprehensive inquiries on Germany - historical and contemporary - that can be easily integrated into pre-existing curricula as a means of comparison and contrast. This textbook is organized into four focus sections: Geography, History, Contemporary German Society, and Sustainability. Inquiries are designed using the Inquiry Design Model (IDM), which focuses on the main elements of the instructional design process as envisioned in the C3 Inquiry Arc Framework for Social Studies Standards.
