Abstract:

Wishful thinking, but wouldn't it be nice to have a GradeMyProjects package in R that would have functions to take a turned in student project or homework assignment, check the work, identify errors, and assign a grade? That's probably a long way off, but we'll discuss and illustrate one small step in that direction, namely the use of an R Markdown (or R Notebook) document to provide a customized "key" when students are doing an assignment with individual datasets having a common theme or structure. For example, we might have students get data on price, mileage, and age for a sample of a particular make and model (their choice) of used cars, then ask them to work with various regression models. Each student (or group of students) has a different dataset (and thus different answers to whatever questions are asked), but the instructor can create a generic R Markdown document to do the required analyses and provide a custom set of solutions when applied to each student's data.
