"All Statistics are Wrong, but Some Statistics are Useful"

Abstract

Imagine if scientists, statisticians and policy makers practiced what we teach. They would rarely be able to say anything about causation in realistic settings because experiments, however ideal, are often impractical. They would have to qualify every conclusion with an unverifiable "if the assumptions hold." When faced with data from a non-randomized trial, they would be paralyzed by "other factors" which might be the underlying cause of the observed effect. Instead of being empowered by their study of statistics, they would be hobbled.

We believe that students in introductory courses should see how and why statistics can guide them in making decisions and taking action in realistic settings, even when data are observational and confounded. We share a broad vision of the importance of modeling, simulation, and computation and have reconsidered many traditional topics in introductory statistics and statistical literacy courses. We'll describe and debate the sometimes differing steps we've taken to make our courses relevant to decision making and consider opportunities for - and obstacles to - making change happen.

"Envisioning a Future Teacher of Statistics in K-12 Classrooms"

Abstract

Over the last 20 years in the U.S., statistics and probability have become a more prominent part of K-12 curricula. Advanced digital tools have also radically changed what is possible in the teaching of early statistics and probability concepts. While teacher preparation programs are making progress in providing appropriate courses and experiences for preparation for teachers to engage K-12 learners in meaningful statistical tasks with digital tools, these programs may still be lacking elements to prepare the next generation of teachers of statistics in K-12. This session will highlight content from the Common Core Standards for Mathematics, and digital tools to enhance learning statistics. We will consider possible ways to envision a future teacher of statistics and take a critical stance towards future directions in K-12 curricula and preparation of teachers for K-12 statistics education.

About the speaker

Hollylynne Lee is an Associate Professor of Mathematics Education at North Carolina State University. Her work in statistics education, spanning 15 years, began with developing the Probability Explorer software and conducting research on young learners' ability to reason about probabilistic phenomena through a simulation approach. This work, combined with her focus on using technology tools in teacher preparation, led to several NSF grants to consider how to best prepare mathematics teachers to teach with technology. Her work has led to numerous research publications and two textbooks for use in teacher preparation. She is a two time awardee of the National Technology Leadership Initiative Fellowship, in 2002 and 2012, co-sponsored by the Association of Mathematics Teacher Education [AMTE] and the Society of Information Technology and Teacher Education. Hollylynne is currently a member of the Technology Committee for AMTE and the Research Advisory Board of the Consortium for the Advancement of Undergraduate Statistics Education, and has participated in several working groups sponsored by the ASA on the future of statistics education research and graduate programs.

"Energizing Higher Education for Statistics and Beyond: T=(IE)2"

Abstract

The T in the title represents the T-shaped education, which places emphases on both depth and breadth. There has been rather substantially increased attention to and demand for developing T-shaped students, who will not only possess the traditional in-field expertise but also a broader set of perspectives, knowledge, and skills, especially communication and social skills. Interdisciplinary Education, the first IE in the title, which includes learning opportunities of an interdisciplinary nature and from a wide variety of fields, is well understood to play a critical role in providing the broad perspectives and skill sets our students need in T-shaping themselves. Statistics, being fundamentally an interdisciplinary field, therefore has much to offer for T-shaped education for all students, regardless of their majors or minors. Intriguingly, the T-shape metaphor also provides a recipe on how to achieve T-shaped education in a more engaging way, with interdisciplinary education only representing its horizontal stroke. There is a vertical IE that can greatly reinforce and complement the first IE. The meaning of this second IE can be inferred from the rest of this sentence or discovered at the talk, which will provide my experiences and observations of its effectiveness from having led or co-led two Graduate Seminars for General Education: Stat 305: Statistical Fallacies and Paradoxes: A Cartoon Guide and Stat 265 (co-taught with Joe Blitzstein): Statistical Mathematics.

About the speaker

Xiao-Li Meng is the Dean of Harvard University's Graduate School of Arts and Sciences (GSAS), Whipple V. N. Jones Professor and former chair of Statistics at Harvard, an Honorary Professor of the University of Hong Kong, and a faculty affiliate at the Center of Health Statistics at the University of Chicago. He is well known for his depth and breadth in research, his innovation and passion in pedagogy, and his vision and effectiveness in administration, as well as for his engaging and entertaining style as a speaker and a writer. Meng received the 2001 COPSS (Committee of Presidents of Statistical Societies) Award and was elected Fellow by Institute of Mathematical Statistics (IMS) in 1997 and by American Statistical Association (ASA) in 2004. He is internationally known for his Real-Life Statistics: Your Chance for Happiness (or Misery), a general education course at Harvard that he designed and taught with the help of his "Happy Team," a dozen masters and PhD students in statistics. Meng advocates that faculty members at top research universities should possess "both beautiful minds for research and beautiful hearts for teaching."

"The Need for Speed in the Path of the Deluge"

Abstract

There is a rapidly increasing awareness of the so-called "data deluge": the explosion in quantities of data being collected, the explosion of settings in which it is being collected, and expansions in the conceptions and scope of what constitutes data. This is accompanied by advances in ways of visualising data and accessible data-visualisation tools. Consequently, it is imperative to find ways to get students much further, much faster and with better comprehension - a quantum leap in ambition. What can make this possible are some of the same things that gave rise to the deluge, computational power and clever software. We will advance some strategies that envisage maximising awareness and excitement about data and what it can do for you and only later back filling details. We also provide glimpses of two software projects beginning to enable such a future - a fleeting encounter with some data-analysis software followed by a more in-depth look at visualisation approaches to bootstrap and randomisation inference.
