The instructional concept guide is part of a system developed for tutor training and support. It is primarily designed for volunteers, but it can also be adapted to the training of paraprofessional tutors for any type of adult literacy program. A key component in the system is the Tutor Support Library, consisting of Instructional Concept Guides (training and reference aids for tutors) and Functional Content Units (models for the practical application of tutoring skills). Guide Three describes planning for following sessions based on an evaluation of the first lesson. Topics presented are: assessment of student performance, lesson planning for session two (including vocabulary learning and free reading), planning for lesson three (oral rate and comprehension assessment), and further assessment and long range planning (according to ability level). Forms for recording student performance and plans are included. Sample informal tutor log notes and sample lesson plans for two ability levels conclude the guide. Guide Three is designed to be studied by the tutor after Guides One and Two. (Author/MS)
