SMoL
What is This Thread’s Purpose?
This thread consists will help you learn the Standard Model of Languages. It begins with a simple version of the model and becomes progressively richer.
In one kind, you will work with an automated tutor that we have built for you. You work through the material at your own pace. You will also be given illustrative programs to run through a program tracing tool that we have built for you.
In the other kind, we ask you to reason about system states to build on what you have learned from the tracing tool.
In general, it’s not hard “cheat” on these tasks; we haven’t tried to make it difficult to do so. But if you do, you will find the later parts of the course virtually impossible. So please work wisely.
Recall that for this track, you are not allowed to discuss work with others while the assignment is in progress or with people who are using late days.
Time
Each module should take 10-20, and at most 30, minutes.
Grading Standard
The tutor automatically tells you about the correctness of your work.
On the Stack assignments, what we most care about is that you make a good-faith effort on these tasks.
Software
Note: The tutor is new software. Currently, it does not have the ability to save state. That means you should finish every module you start; you can’t pause and resume it later.
Software to install (atop DrRacket): SMoL family of languages. Please follow instructions on that site. We may make periodic updates to these systems, which we will announce on EdStem. The URLs include update instructions.
