Writing is, obviously, an important form of communication. As a form of communication, good writing requires clarity, sensitivity to one’s audience, and awareness of stylistic conventions appropriate to the nature of the communication. More importantly, however, good writing (or good communication in any form) requires having something to communicate in the first place. A firm grasp on the issues at hand, and an ability to form a coherent, logical argument are therefore essential to persuasive writing. This course mainly develops these latter skills, for example, skills of identifying issues, forming opinions, gathering evidence in support of opinions, and compiling the results into a compelling text. However, in the process of developing these skills this course also reinforces your ability to write clear prose.
Issues, opinions, arguments, and writings without a subject are pointless. This course therefore uses secret codes as an entry point to discussion and writing. Much of this discussion and writing will actually deal with issues surrounding the codes in our readings rather than with the codes themselves, although we will also spend time during the semester looking at some of the history, mathematics, and technology of cryptography.
Learning Outcomes: On completing this course, students who meet expectations will be able to…
This course is designated as “face-to-face.” I interpret that to mean that class meetings will be in person as much as possible, but not to preclude all forms of online learning. In particular, there may be days when I want you to work in small groups, which will probably be safest if we meet via Zoom or a similar video meeting tool instead of meeting in person. I will warn you about these classes well in advance. So that these meetings can run smoothly, please be sure you have Zoom installed on your computer before the first one.
For each topic we study, I will generally follow a pattern that begins with you reading (or maybe watching a video, etc.) about the basic ideas of that topic, then talking about it in class. After each class meeting, I will produce a summary of the key ideas, questions, and answers from it, and post the summary online. Perhaps every one to two weeks, I will ask you to try working with ideas more on your own via a homework exercise. You will also meet with me to discuss each of these exercises and to hear my feedback. Each of these aspects of the course, i.e., readings, class conversations, notes, homework, and meetings, contributes to your learning; you will find it easiest to get the most out of the course if you do all of them. However, there is also a certain overlap between the different parts of the course, so that if you can’t do one, especially if it’s only for a limited time, you can probably make up for it by working a little harder with the others. So if, for example, you have to miss some class meetings for illness or family emergencies, don’t panic! You should still be able to participate and succeed in the course through the other channels. Naturally, not engaging with enough of the course will eventually lead to an unrecoverable situation, but the course format deliberately accomodates occasional situations in which you can’t do everything.
In the event that we switch to fully online instruction, we will continue the pattern described above, but with class meetings via video chat instead of face to face. All other components of the course (e.g., readings, summary notes, etc.) will continue unchanged.
We will read the following works in this course. Some are available online, and others in print. I have given URLs for the online readings below. The print ones are available from the College bookstore and other sources.
Edgar Allan Poe, The Gold Bug Available online in The Works of Edgar Allan Poe at http://www.gutenberg.org/etext/2147 (easiest to read) or http://www.archive.org/details/worksedgarallan00markgoog (greater variety of formats).
Robert Harris, Enigma Available in print
Hugh Whitemore, Breaking the Code Available in print
The (required) writing manual is
Graff & Birkenstein, They Say, I Say (4th ed.); available in print.
We will occasionally refer to material in Geneseo’s self-enrolled, non-credit “Conventions of College Writing” Canvas resource. To enroll yourself for access to this resource, visit

Edgar Allan Poe’s “The Gold Bug” makes occasional use of the racial epithet “n----.” This word is an overt symptom of a much deeper racist thread running through much American entertainment, which we will look at in detail when we read the story. Until then, if you would prefer to read a version of the story in which the word is censored (as in the preceding sentence), you can find one at

Grading in this course will be very different from what you are used to. The main reason for the unusual grading is that I am trying to consciously undo some of the small ways in which conventional grading unconsciously disadvantages certain students. But beyond removing disadvantages for some, I believe that what I am doing also offers significant advantages to everyone.
There are 3 main ways in which grading in this course will probably differ from what you have seen before.
“Achieving” an outcome has two components: content, i.e., what ideas you know, and depth of understanding, i.e., how thoroughly you understand those ideas. This course’s learning outcomes define both components. Generally speaking, the nouns in the outcomes correspond to content, i.e., things you will learn about. Verbs in the outcomes indicate depth of understanding, i.e., things you will understand the content well enough to do.
I will give you a numeric grade for each outcome in an exercise, based mainly on the discussion of solutions and similar problems — in other words, getting the right answers matters, but is not the only, or even the main, determiner of your grade. Grades range from 0 to 4, as follows:
4 | Mastery as required by the learning outcome throughout the exercise |
3 | Approaching the required mastery; you can describe clearly how to solve most problems arising from the exercise and why, but make mistakes in the details of doing it |
2 | Partial mastery; you can correctly solve most problems but not explain how you solved them or why you used the methods you chose |
OR you can explain and correctly solve roughly half of the problems but not more | |
1 | Initial steps towards mastery; you can begin doing the exercise but not carry solutions to completion or explain how you would do so |
0 | No understanding of this outcome yet |
Although I will grade each exercise, mastery grading isn’t about how you do on any specific one. It’s about how well you’ve achieved outcomes by the end of the course. To that end, there are two other important points about exercises and their grades:
You will “turn in” each exercise by sharing your solution with me during one of your individual meetings. During that meeting, we’ll go over your solutions and answer any questions you have about them, and we’ll also discuss how you came up with those solutions and how you would approach similar problems.
Finally, when this course ends I will give you a letter grade for it based on the numeric grades. My approach to this is that B grades (including B- and B+) indicate that you generally met the expectations of the course, A grades that you distinctly exceeded them, and grades below B- that you fell short to varying degrees. However, I won’t decide the exact cut-offs between grades until the end of the semester, when I see how grades actually worked in practice. During the semester, you can use the mastery rubric as a qualitative guideline to how you’re doing — for example, it says that 3 out of 4 points, or 75%, is “approaching the required mastery,” so an overall average of 75% should indicate that you’re doing OK but maybe not quite as well as desired. I will be happy to discuss your grades with you at any time during the semester and give you my sense of what letter grade, or range of letter grades, I think you are heading for.
In the context of the COVID-19 pandemic, it is vital that we all do what we can to protect the health and safety of each other. If you are feeling unwell on a day that class meets, do not attend. It is better to stay home if you are not feeling well than to attend class and risk spreading illness to others. I have designed this course so that you can progress through it without some or even all of the in-person class meetings, so not coming to class won’t affect your success in it. However, please do communicate with me about absences, and contact the Dean of Students if you expect to be out for an extended period of time.
Face masks are required in all instructional spaces (including classrooms, lecture halls, and laboratories) and all common areas including residence halls and academic buildings. If you forget your mask, please pick up a disposable one before entering the classroom. Masks must be worn for the duration of class. If you do not have a mask or are unwilling to wear one, do not come to class — I cannot safely hold class unless all students are wearing face masks.
Similarly, seating in the classroom has been arranged to preserve social distancing. Please respect it, and do not rearrange classroom furniture. Try to maintain a safe distance between yourself and others at all times, including when entering and exiting classrooms.
This policy applies to me as well as to you. If there is a day when I am feeling ill, I will switch the class to online activities instead of holding an in-person class. Similarly, I will wear a mask throughout class and other meetings, and try to always keep an appropriate distance between myself and others.
Assignments in this course are fundamentally learning exercises. You are therefore welcome to help each other with them, unless specifically told otherwise in the assignment handout. However, solutions that you turn in must represent your own understanding of the solution and must be written in your own words, even if you got or gave help on the assignment.
If you use sources other than this class’s textbook or notes in order to do an assignment, you must include a comment or footnote citing those sources in your solution. Similarly, if you get help from anyone other than me you must acknowledge the helper(s) somewhere in your solution. (But note that I generally think learning from outside sources and people is a good thing, not a bad one.)
I will penalize violations of this policy. The severity of the penalty will depend on the severity of the violation.
