Assessment

Formative assessment

Each unit of the module includes student handouts and exercises that can be used for formative assessments. In addition, each unit includes a set of short answer questions that can be given to students as homework, on quizzes, or on exams.

Summative assessment

The overarching Module Goals are:

1. Students will be able to identify common buried targets (objects) in urban environments that can be found with GPR.
2. Students will be able to explain the basic physics of a GPR system (i.e., pulse transmission, wave propagation, reflection, two-way travel time, wave attenuation, ground properties.)
3. Students will be able to recognize a diffraction pattern as the GPR response to a point reflector/object/feature.
4. Students will be able to estimate ground velocity from diffraction patterns using real GPR data (collected or provided) and determine the depth of objects.
5. Students will be able to describe the limitations of GPR including different targets that give similar-looking responses and the role of soils and geology on data quality.

Summative assessment of these goals can be achieved via the short answer questions embedded within each unit. Alternatively, student performance on the case study exercise in Unit 3 can be considered a summative assessment for the module.
