Evening study-halls have been adopted by all our intro-physics courses:
PHYS 170/171 life sciences majors
PHYS 180/181 life science+engineering majors
PHYS 200/201 advanced- physics/engineering majors
Study-halls are usually 3 nights a week (7-10pm or 8-11pm) held in the TEAL classroom where instructors and course TAs are available to help students while they work on homework and class assignments.
Study-halls have become extremely popular and well-attended in the last few years by creating a collaborative and inclusive environment among students and course staff, where all questions and discussions on course material are welcome, and students can very effectively work together on challenging homework problems and develop physics skills.
