In the fall of 1985, the Educational Computer Consortium of Ohio (ECCO) presented an extensive series of workshops on Logo. The workshops were divided into two categories: those for teacher-trainers and those for classroom teachers. This booklet presents materials developed by a core of five participants in the workshops for trainers using Logo that could be taken directly into the classroom. These materials are presented in two major sections: Logo in Language Arts and Social Studies, and Logo in Math and Science. Activities for teacher training are included. Each section begins with materials presented by Michael Tempel of Logo Computer Systems, Inc., in a series of workshops for teacher trainers. The second part of each section contains materials used in workshops for classroom teachers, which are designed to be directly usable by students in the classroom, and include student worksheets and teacher information sheets. Listings of Apple Logo II files for teacher training and student activities are appended. (RP)
