SNAP has developed sets of tools to support educators in designing and using performance assessments for 3-dimensional science standards, such as NGSS. Free online courses provide instruction on how to use these tools to support professional learning communities in learning about and developing NGSS assessments.
Resources for using performance assessments to inform instructional decisions
Open-ended performance assessments that engage students in sense-making around a phenomenon hold tremendous promise for supporting students' progress with multidimensional reasoning. But for these assessments to support NGSS classrooms, educators must understand how to find evidence of each dimension in students' responses and how to use this evidence to inform instructional decisions. The tools you will find below are designed to guide groups of educators in practicing doing collaborative analysis of a performance assessment. Examples embedded in the tools are based on SNAP's Natural Hazards Short Performance Assessment, which can be downloaded below.
Resources for developing 3D performance assessments
In SNAP's vision of high-quality assessment for NGSS, classroom assessment blends almost seamlessly with instruction. Students are presented with a challenging task or problem, and through discourse, group work, opportunities for peer feedback, and scaffolded learning experiences, they build their expertise so that they are prepared to do their best possible work on a summative product. Our design tools use SNAP's design principles as a foundation to guide developers in building instructionally-embedded performance assessments (IEAs) that elicit actionable information about students' progress with the dimensions being assessed.
Resources for evaluating the quality of 3D performance assessments
Once a 3D performance assessment has been designed, we need to evaluate the assessment to ensure that it meets our goals for quality. SNAP analyzes multiple facets of the assessment, including the degree to which students provide evidence of the dimensions we set out to measure, coherence of the task fro the student's perspective, accessibility, engagement, how sensitive the task is to student performance from the developing to excelling levels, and many others. The toolkit provided here includes frameworks and analytic tools that support these analyses of the quality of a performance task.
