  • The Exercises

    Short and Focused
    CodeLab exercises are short, focused on a particular topic and automatically evaluated. The exercises range from "one-liners" like a variable declaration or an assignment statement to more complex probelms involving loops, functions or methods or even small class definitions.

    Graduated
    The first exercises are simple enough that a beginning student can start working right away. Then as the student progresses within each concept, the exercises build upon each other and gradually become more complicated.

    Immediate Feedback
    These exercises are similar to the short homework problems at the end of each chapter in a textbook but CodeLab gives the student immediate feedback on their answer. With each submission, the instructor's roster is automatically updated. Our instructors have reported that their students are more likely to complete CodeLab exercises because of the immediate feedback and guarantee of confirmation of correctness.

    Topic Coverage
    Our exercises start with the imperative programming core of Python, C, C++, and Java and then go on to address procedural and object-oriented programming. The exercises are targeted at a typical CS1 syllabus.
    What our students say
    "I signed up for this at the start of the semester and thought it was going to be just tedious work, however it turned out to be very helpful in understanding some of the concepts in C programming." Greg M., Student, University of Akron. (more)

    What our instructors say
    "Our students and instructors credit the labs and the CodeLab for improved marks..." Jeremy Sills, Professor , University of Toronto

    "CodeLab has indeed proven invaluable..." Glenn Jones, Professor Medgar Evers College

    "It has helped me cover more material with better comprehension..." Marcus Darden, Professor, Olivet College


    What instructors say
    "So far I am getting more questions about concepts, software engineering and problem solving and fewer questions about Java basics - which is very good news!!" Rose Williams, Professor, SUNY/Binghamton. (more)
