Dear student,
My name is Charles Witschorik, call me Charles, and I want to welcome you to my asynchronous discrete mathematics course at Foothill College. More than 400 students have successfully taken this course since 2021 and I will be delighted to add your name to the list. In this course you will learn about the mathematics that underlies computer science. We'll start with logic, arguments, and proof, follow sequences without bound, set our sights on sets, functions, and relations, count more rigorously than you may enjoy, connect graphs to sets, functions, relations, and trees, and order algorithms using functions.
If that seems to be a lot of topics, you are right. But we will be on a survey expedition so you will have time to see the forest and the trees. And the questions and actions of the students who precede you have already cleared paths through the forest that you can follow.
If you are curious about the mathematical fundamentals of computer science, and you have the time to participate fully, you will do very well in my course. Again, welcome.
Class opens online on Monday, September 25, and both the Canvas portal and the WebAssign homework system will be available. Orient yourself to the course by visiting the Canvas, Day 1 Orientation page, and completing a brief orientation quiz. The module for Week 1 assignments will be opened after you successfully complete the orientation quiz. Week 1 will end with a quiz of material discussed in the assignments. There is a Zoom office hour on Tuesday if you want to meet me live, online.
This course is open for 11 teaching weeks and one week for final exams. You will engage with the course by logging into the Foothill College Canvas portal and selecting Discrete Mathematics, Math 022.03W. Every week a module will open with new topics. Walk through the list of actions and lectures and participate as directed. Each week sections from one chapter of the course textbook are featured. Homework for the weekly sections is preassigned in the Cengage WebAssign online homework system, where you can see the homework due dates and follow your completion progress. A quiz is opened in Canvas at the end of the week to reinforce your understanding of the week's material. The weekly quizzes have due dates and duration times, and rules for engagement with academic integrity, and they are not proctored.
In the twelfth week of the quarter you will register for a one-hour, proctored, cumulative final exam that must be taken on-camera. Further details of course operation are presented on the Canvas orientation page.
At the beginning of every course week, scan the activities in the weekly module and create a personal schedule for reading the textbook, viewing lectures, completing homework, and taking the weekly quiz.
Plan to take the weekly quiz as soon as possible after it opens. Quizzes open at the end of a week, but close in the middle of the next week. This flexibility in the time you take the quiz is meant to give you the room needed to deal with life circumstances. It is not a good idea to default schedule the taking of the weekly quiz to the last possible moment. Every Monday a new weekly module opens with new requirements on your time and concentration. Plan to complete your chapter studies, including the quiz, in the week allotted to the chapter.
Communicate with fellow students via Friday Open Mic throughout the quarter (see below).
Ask questions about WebAssign homework problems using the "Ask Teacher" button in WebAssign.
Ask general questions in email to witschorikcharles@fhda.edu.
Stop by my Tuesday office hour at 1:00 pm for face-to-face discussions with me.
Use email to setup a special time to meet with me online, as an individual or a group.
I am online throughout the day with immediate access to email and WebAssign questions. When you have a question, ask it. If you want to talk face-to-face stop by my online office hour.
I will answer your email and WebAssign requests as soon as possible, but no later than 24 hours after they are received.
Every week, on Friday, a student discussion, called Friday Open Mic, is scheduled, with the question: what did I learn, or not learn, this past week, and how does everyone else feel about their progress? Take advantage of the discussions to create a virtual mathematical community. Be kind, be vulnerable, be supportive, be informative, be inquisitive. Learn with and from each other.
Monday, September 25, Complete day 1 orientation and pass the orientation quiz.
Starting Monday, September 25, view all lectures for sections in Chapter 2, Propositional Logic.
Starting Monday, September 25, Complete Chapter 2 homework in WebAssign.
Starting Friday, September 29, Participate in Friday Open Mic.

Open communication with me when life intrudes in your studies
I am teaching if, and only if, I am helping you learn. I believe that students learn best by repeated activity in a community of curious others; by reading, listening, questioning, sharing, trying, testing, and repeating. And of all the steps, interacting with your classmates may be the most important. Mathematicians have always advanced knowledge by sharing their work and benefiting from its critique by other mathematicians with widely diverse backgrounds and viewpoints.
Classically, quizzes and tests are summative, are returned with brief comments on errors, and many students never deeply understand the questions they missed. My assessments are formative, and students are able to review a detailed analysis of an assessment after the fact, before they are given an opportunity to retake the assessment to correct misunderstandings.
In an asynchronous course, interacting together to create a community needs even more attention than in an in-person course. I rely on end-of-week dialogues, called Friday Open Mic, to stimulate conversation on both the topics of the week and the human emotions of frustration, elation, boredom, and fascination, that often accompany the learning of mathematics.
I learn more every quarter about mathematics from the questions of my students. I try to share that growth in my understanding by recording micro-lectures that explain challenging homework exercises in great detail, including meta-comments on the purpose of an exercises in the course structure. The number of micro-lectures grows with every class I teach, extending the value of student questions across time.
To help to create a virtual community of all students who have ever taken my classes, all students can enter notes and videos into a Course Attic, a repository of messages from current students to future students in discrete mathematics.
Monitor yourself. Are you following your plan for reading chapter sections, viewing lectures, completing homework? If not, adjust your plan and recommit to it. Share your experience with your classmates in Friday Open Mic.
Ask questions of yourself, others, and me. If something still doesn't make sense after reading, viewing lectures, talking with tutors and other students, send me an email and point me to the problem--in the textbook, in the lecture, in the homework--and I will respond.
Be kind to yourself. New vocabulary and methods take time, and repetition, to durably understand. Make sure to rest, relax, and return, when the details are not sticking with you.
Mistakes are just measures of what still needs more attention. Use mistakes to help you adjust your study habits, and try again.
Sometimes you need to push on. New concepts, or embellishments of old concepts that reappear in new material, are sometimes just what is needed to break through a mental road block.
Remind yourself that you are not alone. Many students, just like you, have had to struggle with the pace and content of discrete mathematics, and by persistence, and with help from each other, have succeeded.
With a good-faith effort, growth mindset, and successful completion of the activities in this course, you will reach the following goals:
Use formal logic in constructing valid arguments.
Write proofs formally, including writing proofs using symbolic logic and Boolean algebra.
Use number theory to solve problems.
Understand the basics of set theory, including solving problems in combinatorics and probability theory.
