Consistent concept mastery assessments are among the best ways of testing student understanding. We believe that giving students the chance to concisely and consistently practice what they learn is very useful. As a result, I implemented this check-in quiz framework for students and lecturers alike to use, including a completely reusable autograder. These exercises are optional, but provided every week for students to use. This is just one example of what I'd love to do for students as a co-lecturer!
First, students clone this repository to the myth machines or to your computer if you have the GNU compiler, g++, installed (git clone https://github.com/snme/cs106L-mastery). Then, students will open the exercises.cpp file and fill out the exercise functions. Function and inline comments describe the check-in exercise to the students and tell them where to write their code. Lastly, to check their answers, they would simply run ./autograder! If they got any of the tests wrong, the autograder prints out the expected output and student output. Here are the files inside this directory:
exercises.cpp: Where students write their code.solution.cpp: Solution code (displayed for convenience and ease of use (i.e. you can copy and paste it intoexercises.cppto test the autograder), but in reality, we'd just provide them with the compiled executible).test_cases: The test cases run by the autograder on student code.autograder: A completely reusible python autograder that I implemented from scratch! It compiles the solution and student exercises file, runs each of the tests intest_cases, and compares the output. It provides a report of which test cases were incorrect, the expected and student output, and how many test cases were successfully passed.
