FOURTH-GRADERS CAN DO SIMPLE INVESTIGATIONS BUT STRUGGLE WITH EXPLANATIONS AND MORE COMPLEXITY
The NAEP interactive computer tasks enabled fourth-graders to interact with science problem-solving situations that would have been difficult to re-create in a paper-and-pencil classroom environment. In this task, students were first asked to consider how sunlight affected both a sun-loving and a shade-loving plant. This part of the task was fairly simple and students at all levels were largely able to perform the procedures, while the more challenging investigation of the effects of fertilizer required students to be more strategic and was therefore more difficult for students.
