A few of my colleagues here at YorkU have expressed an interest in using Python with Virtual Programming Lab on our Moodle-based eClass Learning Management System. I don't have a lot of Python experience, having only really used it for some data processing and toy embedded system demonstrations in the past. So I adapted the […]
This is the fifth in the series of postings on automated grading in C. Here, I've modified the VPL exercise to include four possible flowcharts that the students can implement, but the particular flowchart now get assigned to the student based on the time of day. The VPL output (both "run" and "evaluate" looks like […]
This is the third post in the series on evaluating student assignments in VPL with C and unit testing. We're targeting using VPL on Moodle / eClass. Specifically, the bash scripts are based on the fantastic work of Smith College professor emeritus, Dr. Dominique Thiébaut. He wrote about his VPL work here and while his […]
Heard about Virtual Programming Lab (VPL) and eClass at York and want to "kick the tires" a little? If you haven't already, VPL is a plugin for Moodle (eClass at YorkU) that allows instructors to create interactive programming activities for students. Here is some introductory material. [this may need an update after the update in […]
It's important to have dynamic 24/7 interactive activities for programming classes. There are plenty of solutions out there, including Matlab Grader and Möbius. The folks at Jetbrains have their Academy system, too. What I need, at this stage, is a no bells-and-whistles, auto-grader for Matlab code that can run a unit test on a student's […]
In the previous post I showed you how to use VPL and simAVR together to write a basic activity that would test to see if a student could change or assign the value of a register in the simulated microcontroller using the C programming language. While it was the most straight-forward way that I could […]
In our first year programming class for engineering students, EECS 1021, we're using modern features like jShell and var. Unfortunately, the OS that our VPL instance sits on came with an older version of Java, so we've had to modify our scripts to point to the Java 17 JDK. If you get an error like […]
Unit testing is really important in general programming, but it's also really useful when creating interactive programming assignments. With Java, I like to use JUnit and with C I like to use the Unity unit tester. With Verilog it's actually really straight-forward to set up testing frameworks. In the EECS 2021 (Computer Organization) labs written […]
August 2021 Background Here, we're going to apply ThrowTheSwitch's Unity unit test framework to C programs. The test framework is available on GitHub. Three files need to be downloaded from the GitHub. There are a few more files that need to be developed within VPL to make it work, and those are described below. We're […]
One of the places that Moodle falls down in is in supporting math assignments. It occurred to me that we could treat math assignments like we do programming assignments by extending the Virtual Programming Lab plugin for Moodle to support Maple. This doesn't replace existing products like the Maple / DigitalEd Möbius platform, nor does […]
