Wallsheets are used by teachers to instruct or to stimulate the class, are studied by the pupils under the teacher's guidance, or are used by the learners on their own in association with some sort of study guide. This booklet offers a close examination of ways of organizing learning opportunities so that the potential of wallsheets can be realized in relation to the educational needs of children. After a brief introduction, ideas are presented concerning teaching aims of particular lessons, teaching situations, educational purposes that affect design, production of wallsheets, production by children, and storage and display. A short bibliography is also included. (SH)
