Readings

Summary: To improve the quality of our discussions of the various readings this semester, students must submit discussion questions and topics the evening before each reading is to be discussed. This document summarizes my policies for responding to readings.

Introduction

Throughout this semester, I will assign readings from a variety of texts. I will do my best to assign each reading at least two days in advance, although I will usually assign them further in advance. For many classes, you will have readings from Kernighan and Ritchie (designated K&R). For others, you may have Web readings or locally written documents.

In most classes, you will be working on lab. Experience suggests that lab goes more smoothly if (a) students read assignment materials before class and (b) I spend the first few minutes of class going over any questions students had on the reading. Towards these ends, I require you to submit a question on each reading by 9 p.m. on the evening before the reading is due.

Types of Questions

Appropriate types of questions include:

• questions concerning terms not defined in the reading,
• questions to clarify ideas,
• questions to clarify code (yes, you are expected to try to read code),
• questions about the relationships between ideas or approaches,
• questions regarding assumptions behind approaches,
• questions concerning the motivation or necessity of ideas or protocols.

Thus, questions should seek to clarify points of confusion. Simple factual questions are perfectly acceptable. I will assume that students understand issues not covered in questions. You should be prepared to answer questions that you have not asked.

In rare circumstances, you may find a reading perfectly clear. In such situations, you may simply submit a message that says I understood the reading. In those cases, I am likely to call on you to answer questions that your colleagues submitted.

Mechanics

Each reading will have an associated Web page where I will gather your questions. That page will contain a link to a form for you to enter your name and question.

You should submit at least one question for each reading, but you may submit more. Please submit your questions via the linked form before 9 p.m. on the evening before the reading will be covered. For example, if a reading is due on Wednesday, submit your questions before 9 p.m. on Tuesday evening.

I will grade these questions on a Plus/Check/Minus/Zero scale. Most questions will receive a Check. Particularly interesting or valuable questions will receive a Check Plus or Plus. Particularly poor, trivial, awkwardly phrased, or otherwise inadequate questions will receive a Minus. Students who fail to submit their questions on time will receive a Zero.

Students whose questions take the form of I understood the reading will often earn a Check. If they provide particularly good answers when called upon in class, I will increase that grade. If they fail to answer questions when called upon in class, I will decrease that grade.

Potential Changes

Because this is a large class, I may not be able to keep up with the questions. Hence, I may change the ways in which reading questions are to be submitted or the ways I grade them.

I am considering switching to a system based on Piazzza. If I do so, students will receive credit for asking questions and for asking their peers' questions.
