A study was conducted to show that there would be no difference between two samples' abilities to complete a hands-on science project when one is provided with advance organizers and the other is not. The sample of students were second, third, and fourth graders from the science program in Piscataway Township Schools in New Jersey. The experimental sample and the control sample each consisted of 10 randomly selected, heterogeneously grouped students from a suburban community. The experimental sample was presented with an advanced organizer providing information to complete a hands-on science project. The control group was given oral directions to complete the same hands-on science project. Each group was evaluated with the use of a checklist. Results indicated that the use of an advance organizer resulted in no significant difference between the abilities of the control and experimental samples. In fact, the addition of the advance organizer hindered the completion of the science activities. Children left with an advance organizer were somewhat confused about its use and interrupted the examiner with questions. (Thirty-six references are attached.) (MG)
