The document presents a study of the demand of part-time learning in Ontario, identifying learners, would-be-learners, and non-learners, and providing information on how people learn, their intentions for learning, their motivations, and various factors which obstruct their efforts and desires to learn. Chapters, with 157 tables, include: (1) The Study, examining major influences; (2) Characteristics of Learners, providing demographic and socio-economic data on three survey groups; (3) Where Do Adults Learn?, examining six categories; (4) What Do Adults Learn?, analyzing responses; (5) Why Do Adults Learn?, categorizing reasons; (6) Preferred Methods of Learning, presenting survey results; (7) Do Adults Want Credits?, presenting survey results; (8) Attitudes Toward Degrees and Diplomas, presenting data; (9) Obstacles to Participation in Learning, reviewing literature; (10) Cost, Time, Advice, analyzing how much people are willing to give and take; and (11) Conclusions, examining results. Appended material includes: the sample design; a discussion of field work; weighting procedures utilized; variance on selected statistics; the questionnaire; and the Ontario Educational Communications Authority (OECA) regions. Conclusions state that the number of Ontario adults actively engaged in learning is relatively high, but educational opportunities are not sufficiently adapted to the needs of numerous, specific groups.
