This report has had a profound impact on the teaching of introductory statistics in two- and four-year institutions, and the six recommendations put forward in the report have stood the test of time. Much has happened within the statistics education community and beyond in the intervening 10 years, making it critical to re-evaluate and update this important report. For readers who are unfamiliar with the original GAISE College Report or who are new to the statistics education community, the full version of the 2005 report can be found at http://www.amstat.org/education/gaise/GaiseCollege_full.pdf and a brief history of statistics education can be found in Appendix A of this new report. The revised GAISE College Report takes into account the many changes in the world of statistics education and statistical practice since 2005 and suggests a direction for the future of introductory statistics courses. Our work has been informed by outreach to the statistics education community and by reference to the statistics education literature. We continue to endorse the six recommendations outlined in the original GAISE College Report. We have simplified the language within some of these recommendations and re-ordered other recommendations so as to focus first on what to teach in introductory courses and then on how to teach those courses. We have also added two new emphases to the first recommendation. The revised recommendations are: 1. Teach statistical thinking. Teach statistics as an investigative process of problem-solving and decision- making. Give students experience with multivariable thinking. 2. Focus on conceptual understanding. 3. Integrate real data with a context and purpose. 4. Foster active learning. 5. Use technology to explore concepts and analyze data. 6. Use assessments to improve and evaluate student learning. This report includes an updated list of learning objectives for students in introductory courses, along with suggested topics that might be omitted from or de-emphasized in an introductory course. In response to feedback from statistics educators, we have substantially expanded and updated some appendices. We also created some new appendices to provide details about the evolution of introductory statistics courses; examples involving multivariable thinking; and ideas for implementing the GAISE recommendations in a variety of different learning environments. 3 Introduction Background Much has changed since the ASA endorsed the Guidelines for Assessment and Instruction in Statistics Education College Report (hereafter called the GAISE College Report) in 2005. Some highlights include: • More students are studying statistics. According to the Conference Board on Mathematical Sciences (CBMS) survey, 508,000 students took an introductory statistics course in a two- or four-year college/university in the fall of 2010, a 34.7% increase from 2005. More than a quarter (27.0%) of these enrollments were at two-year colleges 1. Nearly 200,000 students took the Advanced Placement (AP) Statistics exam in 2015, an increase of more than 150% over 2005. In addition, many high school students took the AP course without taking the exam or took a non-AP statistics course. At the undergraduate level, the number of students completing an undergraduate major in Statistics grew by more than 140% between 2003 and 2013 and continues to grow rapidly 2. • Many students are exposed to statistical thinking in grades 6 – 12 , because more state standards include a considerable number of statistical concepts and methods. Many of these standards have been influenced by the GAISE PreK – 12 report developed and endorsed by the ASA 3. In particular, the Common Core 4 includes standards on interpreting categorical and quantitative data and on making inferences and justifying conclusions. • The rapid increase in available data has made the field of statistics more salient. Many have heralded the flood of information now available. The Economist published a special report on the “data deluge” in 2010 5. Statisticians such as Hans Rosling and Nate Silver have achieved celebrity status by demonstrating how to garner insights from data 6. • The discipline of Data Science has emerged as a field that encompasses elements of statistics, computer science, and domain-specific knowledge 7. Data science has been described as the interplay between computational and inferential thinking 8. It includes the analysis of data types such as text, audio, and video, which are becoming more 1 http://www.ams.org/profession/data/cbms-survey/cbms2010-Report.pdf 2 http://www.amstat.org/education/curriculumguidelines.cfm 3 http://www.amstat.org/education/gaise/GAISEPreK-12_Full.pdf 4 http://www.corestandards.org/ 5 http://www.economist.com/printedition/2010-02-27 6 Silver, N.

There has been a parallel development of “analytics” as the study of extracting information from big data—particularly with business and governmental applications. • More and better technology options for education have become widely available . These include course management systems, automated homework systems, technology for facilitating discussion and engagement, audience response systems, and videos now used in many courses. Applets and other applications, such as Shiny apps coded in the R programming language, that are designed to explore statistical concepts have come into widespread use. Many general-purpose statistical packages have developed functions specifically for teaching and learning. • Alternative learning environments have become more popular. These include online courses, hybrid courses, flipped classrooms, and Massively Open Online Courses (MOOCs). Many of these environments may be particularly helpful for supporting faculty development. • Some have called for an update to the consensus introductory statistics curriculum to account for the rich data that are available to answer important statistical questions. • Innovative ways to teach the logic of statistical inference have received increasing attention. Among these are greater use of computer-based simulations and the use of resampling methods (randomization tests and bootstrapping) to teach concepts

  • Statistics Education and the Role of Technology
    Statistics Education and the Role of Technology Gail Burrill Mathematical Sciences Education Board, National Research Council, Washington, D.C. The world is changing dramatically. CD’s, the web, caller ID, grocery store debit machines, MRI’s: life today is very different from life thirty years ago. Computer assisted design, spreadsheet cost analysis, simulations, instant communication across cities and nations: the business world is very different from the business world thirty years ago. Information technology is transforming the way we do business and the way we live, and all indications are that even more change is imminent. In education just as in society and in the workforce, technology has the potential to make a profound impact. It can change the nature of the content we teach and the way we teach that content. In statistics, that potential is well on its way to becoming a reality. Although a Danish astronomer, Tyco Brahe, (1546-1601) was one of the first scientists to confront the problem of measurement error (Freedman et al, 1996), even in the early 1700's the nature of statistics was primarily qualitative probably due to the fact that there was very little quantitative data available (Ottaviani, 1989). Quantitative information became a reality in Hungary in 1784 with the first census; the first U.S. census was in 1790. This data was very difficult to manage, and by the late 1880's, a crisis had developed in the attempt to organize and process the large amounts of data collected through the U.S. census. While mathematicians and statisticians had continued over the years to develop statistics as a field, Herman Hollerith in response to this crisis produced a machine that would handle tabulations mechanically (Wallechinsky & Wallace, 1975).

The researchers calculated an overall effect size of 0.566 from 70 studies, for a total of 219 effect-size measures from a sample of n = 40,125 participants. These results suggest that the typical student moved from the 50th percentile to the 73rd percentile when technology was used as part of the curriculum. This study demonstrates that subcategories can further the understanding of how the use of CAI in statistics education might be maximized. The study discusses im- plications and limitations.

  • Statement of Teaching Philosophy Karen E. Nielsen My Primary Goal As an Instructor Is to Help My Students Develop A
    Statement of Teaching Philosophy Karen E. Nielsen My primary goal as an instructor is to help my students develop a strong statistical intuition and the ability to confidently and concisely communicate about their thought process. These are skills that make an excellent statistician, but also an excellent scientist or informed citizen. I think that intuition makes the difference between frustration and appreciation in statistics. In the courses I struggled with in graduate school, I found that I did not understand why things worked the way they did and was frequently surprised by the results I got. Once I was able to develop an intuition that helped me bridge the gap between the theory and applications, I was able to enjoy working through problems and I got excited when results went against my expectations, because that meant I may have found something meaningful, or at least discovered an opportunity to learn and modify my intuition to help me in the future. For example, I want an introductory student to be able to read a problem with example values and know that they expect a fairly small p­value. If they end up getting a large p­value, I want them stop and check their work. They should make sure they used tables, their calculator, and formulas correctly. It’s possible that their intuition was incorrect, so reviewing these concrete steps will help them feel more confident in their answer. Once students have begun to build their intuition, I like to introduce problems that are surprising and may go against expectations that students may have.

  • TOP 10 BENEFITS of STATISTICS in SCHOOLS for TEACHERS the Statistics in Schools (SIS) Program of the U.S
    TOP 10 BENEFITS OF STATISTICS IN SCHOOLS FOR TEACHERS The Statistics in Schools (SIS) program of the U.S. Census Bureau provides data, tools, and activities that educators can incorporate into their lessons to help teach statistics concepts and data analysis skills to students. The activities and resources are segmented by subject (English, geography, history and social studies, mathematics and statistics, and sociology) and grade (from kindergarten through high school) so statistics education can be brought to any classroom. Here are the top 10 reasons the SIS program is good for the classroom: 1 The online resources are free for K-12 teachers. Educators can access, at no charge, more than 100 downloadable activities and resources on the website: www.census.gov/schools. The activities on the website are searchable by grade, school subject, topic, and education standard. 2 Experts from the U.S. Census Bureau contributed to the program. The Census Bureau, which launched SIS, is the primary source of economic and demographic data for the United States. Census Bureau statistical experts were involved in the creation of the program activities, making SIS uniquely qualified to support statistics education. 3 The program promotes cross-curricular education. SIS uses a broad array of Census Bureau data to provide activities and resources for courses in English, geography, history and social studies, mathematics and statistics, and sociology. 4 SIS offers a number of resources and tools, including: • Activities • Games • Maps • Infographics and data visualizations • News articles • Data tools that reveal population statistics • Videos by sex, age, ethnicity, and race census.gov/schools 5 SIS activities were developed by teachers for teachers.

To close the achievement gap and meet new standards of accountability, higher education institutions began looking for methods to increase student access and success. With a growing emphasis on degree completion and quantitative literacy, some researchers began to explore the use of critical pedagogies to better serve a more diverse population (Ukpokodu, 2011). This quantitative study measured the effectiveness of implementing a critical statistics pedagogy in an undergraduate introductory statistics classroom and its impact on course success, persistence, and mathematical empowerment.
