Reasoning and decision making are two of the most important activities in which humans engage. But we don’t always do so in the best manner. When we don’t, the consequences can range from minor inconvenience to catastrophic loss. One of the contexts in which humans have best developed their capacities for good reasoning and decision making is scientific inquiry. Hence, that is where we will turn for guidance. Science is also extremely important to our own decision making as we rely on the results of scientific inquiry. This requires, though, that we understand how science works and be able to assess whether a given result is trustworthy.
Some of the questions we will address are: (1) What makes for a good piece of reasoning in science? (2) Can you ever be absolutely certain of the truth or falsity of a scientific hypothesis? (3) How objective is observation and how can humans avoid making mistakes in perception? (4) What might we learn by systematic observation? (5) What can we learn from discovering correlations between variables and how can we avoid being misled by illusory correlations? (6) What does it take to establish a causal relationship? (7) What are mechanisms, what role do they play in science, and how do scientists discover and reason about them?
This course will emphasize active engagement in the kinds of reasoning and decision making which scientists use in developing and testing hypotheses, especially through on-line exercises and demonstrations. The goals of the course are for students to understand the logical and statistical principles by which scientific claims are created and evaluated and to develop a critical appreciation for the methods by which knowledge is acquired in science. You should leave this course with a better ability to distinguish good from poor reasoning and decision making in science and other domains.
The primary course materials are on the course website at http://inquiry.ucsd.edu. Login directions and initial login codes are included in the course reader, available at the UCSD bookstore (be sure you buy a new reader--used initial logins cannot be reused). The modules found on the website include text, animation, and interactive exercises, of which only the text is included in the reader. Some modules have questions to answer at the end. All activity on the site is recorded and logged, including answers to question sets attached to the modules. Completion of the on-line exercises is a requirement of the course.
Apart from the course package, you will also need to purchase a transmitter for the Inter-Write PRS RF System, the student response system used in this class. These transmitters, informally called “clickers,” are also available at the UCSD bookstore (across from the Infomation Counter) and cost $52.00 (new) or $39.00 (used). You may be able to use the same clicker in other classes, particularly in science classes. Make sure to get a new-style clicker operating at radio frequency (RF) and not an old-style infrared one.
For each module, students are expected to complete it and any questions attached to it, before attending the class for which it is assigned. Attendance in class and sections is required. Final grades will be based 25% on the mid-term, 25% on the final exam, 30% on two-short (1- 2 pages) written assignments, 10% on your "clicker" score, 5% on quizes and participation in sections, and 5% for timely completion of the web-based exercises and questions. The following scale will be used to convert numeric scores to letter grades: 98-100 A+, 93-98 A, 90-93 A-, 88-90 B+, 83-88 B, 80-83 B-, 78-80 C+, 73-78 C, 70-73 C-, 60-70 D, below 60 F. For students taking the course pass/no pass, a C- (70) is the minimum grade for receiving a pass.
Your "clicker" score will be based on in-class questions scored using the InterWrite PRS RF student response system. During each class (except the first), I will ask you to “buzz in” and the system will automatically record your responses, and then transmit them to me. Several times during each class, I will put up a short quiz or poll question for you to answer. For participating in these small quizzes and polls, you will receive one point per class meeting if you click in each time I prompt you to, half a point for responding to some of the prompts during this class and none if you never click in. Your clicker score will be the percentage of points earned divided by the maximum possible. Thus, if you earn 14.5 points and the maximum is 16, your score will be 91%. Important: you must have your clicker every class period to get these points—no exceptions.
In all your work for this course you must observe the University’s Policy on Integrity of Scholarship, which can be found at http://www-senate.ucsd.edu/manual/appendices/app2.htm
There are email distribution lists for this course, one for each section. It
is required that you subscribe to the list for your discussions section. Do
it IMMEDIATELY. You can always unsubscribe later if you drop the course or change
sections. The purpose of the list is to allow the TAs and me to distribute information
regarding due dates for assignments, changes of schedule, etc. Some of this
information is crucial, and some of it may be distributed early in the quarter. To subscribe,
you simply need to send an email message to the address corresponding to your
Section A01 – firstname.lastname@example.org
Section A02 – email@example.com
Section A03 – firstname.lastname@example.org
Section A04 – email@example.com
After you send the subscribe request, you will receive a reply from firstname.lastname@example.org (where * is the number of your section) that will ask you to confirm your request. Follow the directions in this message to confirm you subscription. If you later want to remove yourself from this list, send email to email@example.com.
Only the TAs and I have authorization to send mail to this list. There should be no spam. If you receive mail from this list that is not from one of us, be assured that I will as well and will take measures to block further abuse. (The welcome message you receive suggests that you can send email to the list. Sorry, but you cannot.)
Note: This schedule of reading assignments is tentative and subject to revision. Items in italics are modules on the Inquiry website. You should complete these, including any attached questions, before the assigned class (although subsequent review is certainly encouraged).
Copies of the powerpoints presented in lecture are available on line. (They may well be revised before being presented, and if so, updates will appear around the time of the relevant class.) Click here for access to the lecture notes
