Abstract

Many governments around the world promote computers in schools as an educational and political goal. Often this goal is "a computer in every classroom" and sometimes even "a computer for every student". Although computers are dropping in price, many schools simply do not have the resources to provide a computer for every student. Many schools do, however, have the resources to provide a computer in every classroom. This n--1 ratio of students to computers will lead to students collaborating around the computer. As the student to computer ratio decreases it is reasonable to anticipate that students will move from collaborating around the computer to collaboration using the computer, using both asynchronous mechanisms (like email) and synchronous mechanisms (like peer-to-peer networking tools and collaboration-aware educational applications). Many researchers have designed and implemented many tools and toolkits to support collaborative work and collaborative learning. These range from tools to supporting asynchronous collaboration where the parties are not using their computers at the same time, to tools to support synchronous collaboration, where the users are present at the same time and the tools provide awareness support, so the users are aware of each other. Importantly, there has been little evaluation of how these techniques effect learning. This paper describes an experiment that examines how computer supported collaboration affects 48 eleven year children learning to solve a problem. Our results reveal that girls' performance is hindered when collaborating. We explain how the results show girls who are collaborating use situated action, rather than planned action, problem solving strategy when collaborating. Finally, we argue that this increase in situated action is due to girls feeling unsure of their planning when collaborating.
