Classroom observation provides detailed views of individual classrooms, while walkthroughs provide a broader picture of a whole school or department. Common characteristics of effective classroom observation include informal communication and management by wandering around. The document also discusses using classroom observation and walkthroughs to evaluate instructional practices, not teachers, and to foster collaboration by identifying problems and creating collaborative solutions. A multi-step process is outlined that involves planning, data collection, analysis, and reflection. Student input is recommended to provide rich information.
