5 Young students and future teachers as passengers on the Logo engine Ivan Kalas and Andrej Blaho Department of Informatics Education Comenius University, Bratislava Slovak Republic Abstract In 1994 we released a new version of the Logo language. We now concentrate on research into new educational possibilities offered by this environment. We want to provide Logo users with a strong and flexible developers' tool for exploring, creating and playing. Together with our university students - future teachers of mathematics and informatics - we run a seminar on implementing informatics in primacy and lower secondary education. The goal of the seminar for the 1995/96 school year was to develop a modern one-year course on informatics for lower secondary students, supported by a series of open microworlds which should provide creative laboratories to explore major ideas embedded in turtle geometry, mathematics, multimedia, logic and algorithmics. Keywords Programming language Logo, curriculum development, open learning, teacher education, tools. IN1RODUCTION The main thrust in teaching Logo is the process rather than the final outcome of an activity (Shimabukuro, 1988). In 1994 we released a new version of the Logo language, (Blaho et al., 1994; Stuur, 1994), with the ambition to make use of all the powerful features of the Windows environment and to provide complete support for turtle geometry, enhanced Logo data structures, multimedia, multiple turtles and the handling of complex graphics. Since then our Logo has appeared in more than ten national Information and Communications Technologies in School Mathematics J.D. Tinsley & D.C. Johnson (Eds.) © 1998 IFIP. Published by Chapman & Hall
