During the school year 1977/78 four computers equipped with LOGO and Turtle Graphics were installed in an elementary school in Brookline, Massachusetts. All sixth grade students in the school had between 20 and 40 hours of hands-on experience with the computers, and the work of 16 students ranging from intellectually gifted and average to learning disabled was documented in detail. This volume includes (1) an overview of the Brookline LOGO project, (2) a description of the learning styles of different students who took part in the project, (3) the experiences of students at both extremes of the range of abilities present in a typical public school, (4) a breakdown of the computer programming skills and concepts learned by the students during the course of the project, (5) a breakdown of the mathematical and geometrical skills and concepts learned by the students during the course of the project, and (6) a description of the results of a brief exposure of students to a dynamic turtle which simulates Newtonian motion. Numerous illustrations are included. (Author/LLS)
