Shadowspect is a puzzle-based geometry assessment game designed for 7-10th grade students. Students progress through the puzzles by constructing 3D figures that match given 2D silhouettes.

Why game-based assessment?

In contrast to traditional summative assessments that primarily focus only on the content and are only gathered at one time point, an ongoing game-based assessment model gathers data continuously over time and ubiquitously across contexts and domains.

Digital games have great affordances to assess and support rigorous learning and can be used to connect student learning in and outside of the classroom, allowing them to develop deep understanding of the domain. Second, data generated from gameplay can be rapidly collected without interrupting the learners’ engagement, which means assessment can be seamlessly embedded in their daily activity. Third, extracting such data can yield comprehensive student models, which can be used to support their self-awareness. MIT has already been engaging in this kind of game-based assessment, which has seen success in classrooms.

Assessment in Shadowspect

While students play, Shadowspect gathers data to assess students’ spatial reasoning, creativity, and persistence, as well as the following skills from the Common Core:

  • CCSS.MATH.PRACTICE.MP5: Use appropriate tools strategically.
  • CCSS.MATH.CONTENT.HSG.MG.A.1: Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder
  • CCSS.MATH.CONTENT.HSG.CO.A.3: Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
  • CCSS.MATH.CONTENT.HSG.GMD.B.4: Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
