Gender and science achievement: A case study

Upon completion of a science unit on heat and temperature, the students in a Canadian 9th grade science class wrote two different achievement tests. On a unit test which required students to answer questions that were based on facts students had studied, grades obtained by girls and boys were not significantly different. Conversely, on a post‐test, which required that students apply their knowledge to novel situations, boys achievement was significantly greater than that of the girls, particularly on higher level questions. Classroom observations revealed that few girls contributed to class discussions, whereas most of the boys participated in discussions. It is suggested that the more active class participation by boys may have contributed to their making greater gains in the understanding of heat and temperature concepts.
