The results of a project undertaken to assist the Office of Facilities of the State University of New York in the development of design and planning criteria for "learning spaces" with particular emphasis on the considerations for seating, lighting and acoustics. The learning spaces referred to are classified as large group instructional facilities developed particularly for the utilization of aids and media in the learning process. Much of the work presented in this study is based on the Rensselaer Experimental Classroom Project. Topics discussed include--(1) introduction - existing research general design considerations, and purpose of study, (2) the experimental classroom, (3) seating - introduction, evaluation, and suggested improvements, (4) lighting - general requirements, evaluation, and suggested improvements, (5) acoustics - introduction, general considerations, and critique, and (6) appendix.
