This document combines a students' manual and a manual for teachers. The students' manual is a self-teaching guided discovery manual for junior high, high school, and college students that provides self-paced explorations into recursion. It includes a disk with lessons that are to be used with the written material. There are eight lessons presented: (1) lesson 1 involves performing experiments and examining Logo procedures that introduce recursion; (2) the objective of lesson 2 is to develop a conceptual model for embedded procedure calls that are nonrecursive; (3) lesson 3 explores simple procedures and creating and diagraming recursive procedures; (4) lesson 4 investigates procedures that involve recursion and procedure inputs and reinforces the concept of helpers in recursion; (5) lesson 5 involves learning to use conditionals to stop recursive procedures and practicing diagramming procedures that use stop rules; and (6) lesson 6 explores and predicts the results of procedures that use embedded recursion and looks at patterns and processes within procedures; (7) the objective of lesson 7 is to explore Logo variables; and (8) lesson 8 provides an introduction to fractals. Each lesson section includes objectives, procedures, and discussion. Data sheets are provided to help students evaluate their knowledge of the lesson content. A chart of relevant LogoWriter keys is appended. The purpose of the teacher's manual is to help teachers support students in their learning of recursion. The manual is divided into four parts: (1) part 1 contains the instructions for using the manual and contains guidelines for assessing student progress; (2) part 2 lists references to reading that will give teachers insight into recursion and the teaching of recursion, as well as activities that can be used with a small group or class; (3) part 3 contains masters of the "data sheets" that correspond to those in the student book; and (4) part 4 includes procedure trees and listings of all the procedures contained on the disk accompanying the student package. A chart of the relevant LogoWriter Keys and a list of 17 suggested readings are appended. (TMK)
