Scaffolding is often used to facilitate learning by providing supports that allow students to complete tasks that they would not otherwise be able to complete successfully. The research literature on the types and efficacy of scaffolding in the context of teaching and learning is extensive. Although there are numerous examples of scaffolding in large scale assessment, there is relatively little research related to the impact of scaffolding in this context. With the need to create large-scale assessments aligned to the Next Generation Science Standards, which requires assessing the integration of science and engineering core ideas with practices, knowledge about the impact of scaffolding in assessment tasks on the measurement of students’ knowledge and abilities may have increased importance. We conducted a study using cognitive interviews and classroom data to compare student responses and performance in scaffolded and unscaffolded versions of two tasks that integrate engineering practices with science. The two versions elicited different types of information about students’ abilities that may inform assessment design and development. We also found significant differences between overall performance on the two versions and between the two settings in which the instrument was administered.
