This white paper emphasizes the importance of inquiry-based learning in social studies, highlighting five instructional shifts to enhance student engagement and success. These shifts include crafting compelling and supporting questions to spark inquiry, fostering collaborative civic spaces for applying civic virtues, integrating disciplinary literacies like geography, economics, civics, and history, promoting literacy practices such as argumentative writing and consensus-building, and encouraging students to take informed action based on their inquiries. Inquiry is student-driven, with supporting questions guiding research. Open-ended questions like "Why?" and "How?" deepen understanding, while closed-ended questions like "Who?" and "What?" provide essential background information. Disciplinary literacy is developed through close reading and guiding questions tailored to geography, economics, civics, and history. Students are encouraged to communicate conclusions through debate, deliberation, and diverse formats such as essays, infographics, and public service announcements. The paper focuses on middle school students, acknowledging their readiness to engage with inquiry-based learning.
