Working with a round turtle: The development of angle/rotation concepts under restricted feedback conditions
Computers & Education Volume 28, Number 1, ISSN 0360-1315 Publisher: Elsevier Ltd
This study examines the development of childrens' concepts of angle/rotation when working with a round turtle within a Logo microworld. Children's problem-solving strategies where computer screen feedback is essentially restricted to position only are examined and compared with those strategies adopted within a Logo microworld which provides standard feedback of the screen turtle's position and heading. Some evidence is given to support the idea that a round turtle promotes reflection by distancing the user from the immediate problem and encouraging a focus on related concepts.
