This webinar will discuss the development and teaching of a freshman seminar course. In this course, students investigate the practical, ethical, and philosophical issues raised by the use of statistics and probabilistic thinking in realms such as politics, medicine, sports, the law, and genetics. Students explore issues from fiction, the mainstream media, and scientific articles in peer-reviewed journals. To do all of this, they must consider a wide range of statistical topics as well as encountering a range of uses and abuses of statistics in the world today.

Ethics play an important role in statistical practice. How can we educate our students about statistical ethics--especially when our courses are already packed with so much...statistics? At the Joint Statistical Meetings in August, I was the discussant in a session on "Teaching Ethics in Statistics Class." First, I will briefly review the points raised by the speakers in that session. George McCabe (Purdue) contrasted the "old" introductory statistics course with its emphasis on methodology to the "new" course. Patricia Humphrey (Georgia Southern) spoke about how she covers ethical data collection in her introductory classes. Paul Velleman (Cornell) talked about the role of judgment in statistical model building and how it makes students (and sometimes us) uncomfortable. I will discuss each of these points in the context of the American Statistical Association's "Ethical Guidelines for Statistical Practice" as well as my own experiences in teaching statistical ethics in an undergraduate capstone course for statistics majors. I will close with an example of statistical ethics in the use of multiple comparison procedures.

Statistics 105 is a team-designed course that has received local media attention (e.g., www.news.harvard.edu/gazette/2008/02.14/11-stats.html). Its course description promises the following:
Discover an appreciation of statistical principles and reasoning via "Real-Life Modules" that can make you rich or poor (financial investments), loved or lonely (on-line dating), healthy or ill (clinical trials), satisfied or frustrated (chocolate/wine tasting) and more. Guaranteed to bring happiness (or misery) both to students who have never taken a previous statistics course, and to those who have taken statistics and want to see how statistical thinking applies to so many areas of life.
This webinar will reveal its history, pedagogical motivation, innovations, and challenges along the way.

George Cobb describes the core logic of statistical inference in terms of the three Rs: Randomize, Repeat, Reject. (See repositories.cdlib.org/uclastat/cts/tise/vol1/iss1/art1) Note that all three Rs involve process or action. Teaching this core logic is more effective when students are able to carry out these actions on real data.
In this webinar, I'll show how to use computers effectively with introductory-level students to teach them the three Rs of inference. To do this, I will use a another R: the statistical software package.
The simulations that will be carried out involve constructing confidence intervals, demonstrating the idea of "coverage," hypothesis testing, and confounding and covariation.
Although R is professional-level software, it's very easy to use in an introductory setting, as I have been doing for the last decade. The key is to use flexible and concise operators. I'll provide these to the seminar participants.
To follow the seminar successfully, you do NOT need to know anything about R or computer programming. However, you should install R on a computer so that you can follow along. Instructions for doing this, and a short introduction to simple R commands, are available at www.macalester.edu/~kaplan/ISM/draft-intro.pdf (PDF) (see Section 1.4).
A note from the presenter:
Dear Webinar Participants,
Here are the slides for next Tuesday's webinar. I'm sending them out in advance because they contain information on how to install R and the datasets, etc. for the webinar. The slides also contain some background and extension material that there won't be time to go over during the webinar --- these are the slides marked with a dark band at the bottom.
I'm also attaching a "crib sheet." Although there are just a few commands that you will need to learn to carry out the simulations described in the webinar, it's convenient to have these all listed on one sheet.
This is the first time I have given a presentation using web-based software. I have been practicing a bit. One of the things I have realized is how different the webinar format is from the conventional face-to-face situation. In classes and workshops, I have always liked to have students or participants use the computer at the same time as we are talking about the statistical principles and how the computer supports them. Inevitably, people make mistakes, but these become learning experiences since I am there to help get them quickly back on track.
In the webinar format, however, I have no practical way to see what you are typing in your own R sessions and no way to respond quickly to errors. So, I'm concerned that people who are trying to follow along in their own R session will just get distracted. I suggest that the best way to proceed, if you do get distracted by a small error, is to stop and follow the webinar --- I hate to say it --- "passively." Then, after the webinar, we can sort through any problems in a one-on-one format. I find this regrettable, since I think people learn better when they are actively engaged with the material, and because the basic premise of this webinar is that when students actively implement the logic of statistical inference, they come to a faster and better understanding of it.

This webinar discusses issues and challenges in preparing teachers of statistics at the secondary and college level. We then provide a case study of a graduate level course taught at the University of Minnesota that focuses on developing excellent teachers of statistics. The course is based on the GAISE guidelines and helps the students develop both knowledge of teaching (pedagogical knowledge) and specific knowledge about teaching statistics (pedagogical content knowledge). Topics, readings, activities, assessments, and discussions are described. In addition, we discuss how the course was transformed from a face-to-face setting to an online environment.Watch Webinar Recording (FLASH)

There are many good reasons to incorporate thinking about diversity into a course, not the least of which is that it can have a real impact on student learning and cognitive development. In this webinar, we will explore both how the tools of statistics can help students better understand complex and controversial issues, and, in the other direction, how using these complex and controversial issues can help facilitate deeper learning of statistics.Watch Webinar Recording (FLASH)

Many instructors use projects to ensure that students experience the challenge of synthesizing key elements learned throughout a course. However, students can often have difficulty adjusting from traditional homework to a true research project that requires searching the literature, transitioning from a research question to a statistical model, preparing a proposal for analysis, collecting data, determine an appropriate technique for analysis, and presenting the results. This webinar presents multi-day lab modules that bridge the gap between smaller, focused textbook problems to large projects that help students experience the role of a research scientist. These labs can be combined to form a second statistics course, individually incorporated into an introductory statistics course, used to form the basis of an individual research project, or used to help students and researchers in other disciplines better understand how statisticians approach data analysis.Watch Webinar Recording (FLASH)

There is a large body of research on the mechanisms underlying student learning. In this webinar, we will explore four principles distilled from this research - the role of prior knowledge, how students organize knowledge, meaningful engagement, and goal-directed practice and feedback - and illustrate their application in the teaching of statistics. A more detailed example will be given to show how these principles can be integrated to develop and support our students' conceptual understanding.Watch Webinar Recording (FLASH)

Math majors, and other mathematically inclined students, have typically been introduced to statistics through courses in probability and mathematical statistics. We worry that such a course sequence presents mathematical aspects of statistics without emphasizing applications and the larger reasoning process of statistical investigations. In this webinar we describe and discuss a data-centered course that we have developed for mathematically inclined undergraduates.Watch Webinar Recording (FLASH)
