This document discusses developing inquiry skills in social studies. It explains that inquiry involves investigating the social world and proposing explanations based on observations. Inquiry skills are grouped into five main areas: data gathering, organizing, processing, communicating, and reflecting. Effective teaching of inquiry skills involves modeling skills, encouraging curiosity, and respect for evidence. Lessons should focus on teaching a specific skill through concrete experiences, meaningful practice, and transferring skills to new situations. Planning lessons involves identifying the key skill and appropriate activities to teach and assess that skill.
