Wikipedia's page on Statistics Education gets hundreds of hits every week, but until recently the page gave a very limited impression of our discipline. A group at the University of Minnesota has been regularly meeting since fall 2012 to research, update, and improve the Wikipedia coverage of statistics education. We have only begun to scratch the surface of Wikipedia's power to collect and widely disseminate the what, when, who, where, and why of teaching and learning statistics. Come hear about what we've done so far, and how you can get involved in spreading the word about the resources available to statistics educators worldwide.

Histograms are adept at revealing the distribution of data values, especially the shape of the distribution and any outlier values. They are included in introductory statistics texts, research methods texts, and in the popular press, yet students often have difficulty interpreting the information conveyed by a histogram. This talk will identify and discusses four misconceptions prevalent in student understanding of histograms. In addition, pre- and post-test results on an instrument designed to measure the extent to which the misconceptions persist after instruction will be presented. The results indicate not only that some of the misconceptions are commonly held by students prior to instruction, but also that they persist after instruction. Future directions for teaching and research are considered.

Active learning opportunities can be difficult to generate when teaching large groups of students. In this webinar, I will present an experiment using Sudoku puzzles that can be easily conducted in a lecture with 300 (or more) students. The factor manipulated in the experiment is the type of Sudoku puzzle and there are four types, which are each the same puzzle but with different characters. The experiment yields a rich data set which can be used to illustrate basic statistical methods such as chi-square test for independence of categorical variables, through to more complicated analyses such as survival analysis techniques. I will outline the experiment and give an overview of the teaching opportunities that the data present.

The Common Core State Standards (CCSS) include much more statistics content than previous standards. Their adoption has created the opportunity and necessity for nearly all middle school and high school mathematics teachers to be prepared to teach a substantial amount of statistics. This session will focus on the topic of sampling variability, a topic that is greatly emphasized in the middle and high school grades in the CCSS. We will present a research-based learning trajectory to help guide teacher preparation on this topic. In addition, we will discuss several unexpected misconceptions that emerged while testing the trajectory with high school teachers. As a group, we will work through an activity together to illustrate how to use the trajectory with teachers.

As a part of an opening course survey, data on eye color and gender were collected from students enrolled in an introductory statistics course at a large university over a recent four year period. Biologically, eye color and gender are independent traits. However, in the data collected from our students, there is a statistically significant dependence between the two variables. In this article, we present two ideas for using this data set in the classroom, and explore the potential reasons for the dependence between the two variables in the population of our students.

Our current students are among the first to have been vaccinated against HPV. Have they ever considered how the accumulation of the evidence for the efficacy of the vaccine resulted in recommendations for its widespread provision? Using data sourced from a meta-analysis of clinical trials for HPV vaccines, we will examine this evidence. We will show how these data can be used to illustrate applications of methods of categorical data analysis, for students in courses at a variety of levels. And we will describe how this case study can be used to promote discussion of concepts in the design of experiments, statistical concerns such as independence of observations, and the importance of context in the interpretation of the results of data analyses.

Like many other research universities, the University of Nebraska-Lincoln relies on graduate student instructors to cover a large portion of the instructional load in the introductory course. In order to better prepare new graduate student instructors, we have implemented a mentoring program that pairs new GTAs with experienced graduate student instructors. Through the mentoring program, the new GTA has a semester to acclimate to graduate school and their new role as instructor, and the senior GTA has the opportunity to emerge as a teacher leader.

The Island (island.maths.uq.edu.au) is an online virtual population to support learning and teaching in experimental design, epidemiology and statistical reasoning. This month the Island is celebrating five years since the switch was flicked and the population came to life. In this presentation we will give some examples of how the Island has been used in those five years and suggest some activities for you to try.

In this presentation we will discuss student-directed discovery projects in statistics, which are intended as the means through which statistical content is taught to the students. In particular, we will delineate the purpose and scope of a project covering linear regression analysis and another project covering comparisons with basic t-tests. We will describe curriculum materials developed to help instructors facilitate such projects and provide the web address where these materials can be accessed. We will give examples of how instructors use the curriculum materials to guide students through the projects' stages. In particular, the materials can be used to provide the students with clear information about the project requirements and what activities the students are expected to be engaged in during each phase of the student-directed projects. These projects are truly student-directed in that the students select their own research topic, define their own variables, and devise and carry out their own data collection plan before analyzing and interpreting their data. The students report their results in two forms: a written report is provided to the instructor and a brief formal presentation is made before the rest of the class. In both formats, the students report the findings of their research project, as well as explain why they chose the particular research topic, explain how they gathered, organized and analyzed the data and list any short-comings they perceive in their own project. Our presentation will include specific examples of projects that students have conducted. Finally, we will also discuss the rationale for assigning such projects, including the potential benefits of such projects - benefits suggested by both prior and on-going research - and possible factors mediating those benefits.
