Chernoff, E. J. (2018, May 4th). Counterintuitive Probability Problems: Countering Intuition. Keynote Presentation at the Final Round of the 2018 British Columbia Secondary Schools (BCSS) Math Contest. Thompson Rivers University, Kamloops, BC.

Abstract. The purpose of this session is to deep dive into a handful of famous counterintuitive probability problems. Instead of strictly focusing on the correct answer, however, we will focus on the gap that exists between intuitive, incorrect answers and correct answers. These attempts at countering intuition will reveal that no matter which famous perplexing probability problem is under the microscope, incorrect answers (mostly) stem from assigning equal probabilities to things (outcomes, events, etc.) that are not equally likely. Even as we mind the gap, though, we’re not out of the woods. In the words of Sir David Spiegelhalter, "I often get asked why people find probability so unintuitive and difficult. After years of research, I have concluded it's because probability really is unintuitive and difficult." Please bring an open mind…and an eraser.

Abstract. Having closely followed the "Canadian Math Wars" for over three years now, I, in this keynote, ask (and answer) the following question: Is the Western Initiative for Strengthening Education in Math (WISE Math), as their name suggests, Strengthening Education in Math? Join me for a presentation and a discussion of the hot topics in this debate (e.g., PISA results, new math, curriculum, WNCP, standard algorithms, constructivism, back to basics, calculators, JUMP math, randomized controlled trials, reform math, fuzzy math, textbooks, false dichotomy, drill and kill, spiral curriculum, long division, discovery, paper and pencil, cognitive science, direct instruction, outcomes, curriculum, non-standard algorithms, math facts, times tables, calculators and more).

Chernoff, E. J. (2013, February). Relative Likelihood Comparisons: A Comparative Overview of the Research. Colloquium of the School of Mathematical and Statistical Sciences, Arizona State University. Phoenix, Arizona, USA.

Abstract. In this lecture, a comparative overview of research investigating relative likelihood comparisons will be presented. The lecture begins, of course, with an overview of Tversky and Kahneman’s heuristics and biases program (of the late 1960s and early 1970s) — with particular emphasis on the representativeness heuristic. Second, the alternative theories, frameworks and models that mathematics education researchers used to account for incorrect, inconsistent, incomprehensible relative likelihood comparisons (during the 1990s and late 2000s) will be discussed. Third, the more recent developments to the heuristics and biases program, which have largely and inexplicably been ignored by the mathematics education community, will shed new light on (reasonable) unintended comparisons of relative likelihood. Lastly, the lecture will focus on an emerging area of research that uses logical fallacies (e.g., the fallacy of composition, the appeal to ignorance and others) instead of heuristics and biases to account for prospective math teachers' relative likelihood comparisons.

Chernoff, E. J. (2018, May 4th). The Canadian Math Wars: Coast to Coast to Coast…Almost. Teachers’ Session at the Final Round of the 2018 British Columbia Secondary Schools (BCSS) Math Contest. Thompson Rivers University, Kamloops, BC.

Abstract. Since 2011, the teaching and learning of mathematics has been a staple of local, provincial, and national media coverage (newspapers, radio, television, and social media). This story has legs because, well, the sky was falling! Looking back, was the sky really falling? The purpose of this session is to provide a thorough, historical overview of the most recent debate over the teaching and learning of mathematics, which has become known as the Canadian Math Wars. After getting caught up on what’s been happening in Alberta, Saskatchewan, Manitoba, and Ontario, we’ll discuss the reasons why things were different British Columbia this time around. Time for a lively discussion at the end of the presentation will be strictly preserved.

Chernoff, E. J. (2014, January 22nd). What Social Media Has Taught Me About (Mathematics) Education. Joint Faculty of Education/Mathematics, Science and Technology Education Group Public Lecture. Queen's University. Kingston, ON.

Abstract. In this keynote, an overview of the current state of social media for education (with mathematics providing the subject area context and examples) will be presented. First, the different types of social media being used will be highlighted and detailed (e.g., social networks, blogs, microblogs, social bookmarking, media sharing, aggregators and discussion forms). Second, for each of the different types of social media, I will detail “who” (e.g., individuals and organizations) is using “what” (e.g., Facebook, Google+, Twitter, Tumblr, Delicious, StumbleUpon, YouTube, Instagram, Pinterest, RSS, LinkedIn, Academia, Listserves and others). Third, I will discuss my use of and varying attempts to manage social media over the past four plus years. Lastly, with a better picture of the social media for (mathematics education) landscape, I will explain what social media has taught me about the teaching and learning of mathematics. With any time that remains, I look forward to answering any questions that may arise from the presentation. Worthy of note, my intention is that this talk is relevant and pertinent to all elementary school and secondary school teachers of today's learners and, further, relevant with the Ministry of Education's Literacy Numeracy Secretariat's initiatives for all students across all subject areas.

Chernoff, E. J. (2015, February). Grand Probabilistic Delusions. The Fields Institute For Research In Mathematical Sciences Math Ed Forum: Probability. Toronto, Canada.

Abstract. It is a popular notion that probability is counterintuitive. Sir David Spiegelhalter perhaps said it best: "I often get asked why people find probability so unintuitive and difficult. After years of research, I have concluded it's because probability really is unintuitive and difficult." As one might expect, this notion has been fully embraced by a small band of researchers in the field of mathematics education; however, said research (and results) are not well known. As such, the purpose of this session is to provide a historical overview of the last 60 years of research investigating our grand probabilistic delusions. We will, of course, address and (not without debate) answer some of the perplexing probability problems found in the research literature.

Chernoff, E. J. (2014, July). Will the real Bayesian probability please stand up!? Session 6A: Bayesian inference (probability) goes to school: meanings, tasks and instructional challenges - Topic 6: Innovation and reform in teaching probability within statistics. 9th International Conference on Teaching Statistics (ICOTS9). Flagstaff, Arizona, USA.

Abstract. Whether examined from a mathematical perspective or especially from a philosophical perspective, as Bayesian inference (probability) enters school mathematics curricula world-wide it definitely brings with it "some baggage." On its way to school, Bayesian inference (probability) will also pick up some baggage from the field of mathematics education (e.g., informal inference, "subjective" probability). Further adding to this baggage, mathematics and school mathematics are not one and the same. Through examining Bayesian inference (probability) from the perspectives of philosophy, mathematics, mathematics education and school mathematics (and popularization), this session will, ultimately, try to better establish what is meant by Bayesian inference (probability)...as it goes to school. In other words, "Will the real Bayesian probablity please stand up!?"

Abstract. Concepts and models of uncertainty and variability are at the heart of statistical thinking and analysis. Hence probabilistic concepts and thinking underpin all of statistics. Chance and Data developments should be intertwined, in harmony and both driven by data, real contexts and problem-solving. As in all of statistics, students bring to formal education in probability concepts and intuitions from everyday real experiences, and the teaching of probability needs to build on these and link formal notions to the everyday, to real contexts and – constantly – to data. In order to enrich conceptual understanding and underpin formal developments with experiential insights, sustainable representations of probability, integrated with data and statistical thinking, will render concepts accessible and more easily exemplified. These invited sessions will address much-needed reforms in teaching probability in harmony with statistics and will explore current innovations and new directions.

Chernoff, E. J. (2020, October 23rd). Social Media for Mathematics Education: I've Wasted Years of My Life, So You Don't Have to.... Workshop for the Annual Provincial Mathematics Professional Development Day in Manitoba, Manitoba Association of Mathematics Teachers (MAMT).

Abstract.Full disclosure, for over a decade, I’ve been using for social media for mathematics education. Name a platform (e.g., Facebook, Google+, Twitter, Tumblr, Delicious, StumbleUpon, YouTube, Instagram, Pinterest, LinkedIn, Academia, Listserves and others) and, to varying degrees of success, I’ve used it. Armed with my wealth of experience, it’s time for me to share lessons that I’ve learned. The good, like how I’m able to stay on top of, essentially, everything related to the teaching and learning of mathematics. The bad, for example, the extremely useless information that I’ve had to endure from following people who post a mixture of personal and private information on their various platforms. And, the ugly, like how irrationally irate people because I followed nobody, zero people, on Twitter and other platforms. Ultimately, then, this presentation is my latest overview of the current state of social media for mathematics education. In other words, come see how I’ve wasted years of my life so you don’t have to waste yours when it comes to using social media for the teaching and learning of mathematics.

Chernoff, E. J. (2017, October 23). A crash course in ECUR 312 (Methods in Elementary Mathematics). Featured Presentation at the Saskatchewan Mathematics Teachers’ Society’s (SMTS) 10th Saskatchewan Understands Mathematics (SUM) conference. Saskatoon, Canada.

Abstract. Have you ever overheard a relatively new elementary school math teacher talking about Gordon Ramsay’s Kitchen Nightmares, The Matrix, or perhaps mumbling something about having been part of a detox centre for answer junkies? Well, I’m the one to blame! Having taught nearly 1500 future elementary (and high) school math teachers over the last decade here in SK, the purpose of this session is to share with attendees the central tenets of my Methods in Elementary Mathematics course. In the interest of full disclosure, you may have to write a math test if you attend this session; and, if this bothers you, even in the slightest, please attend.

Chernoff, E. J. (2017, October 24). The sky was falling! The sky was falling! Featured Presentation at the Saskatchewan Mathematics Teachers’ Society’s (SMTS) 10th Saskatchewan Understands Mathematics (SUM) conference. Saskatoon, Canada.

Abstract. Since 2011, the teaching and learning of mathematics has been a staple of local, provincial, and national media coverage (newspapers, radio, television, and social media). This story has legs because, well, the sky was falling! Looking back (and to new PISA results), was the sky really falling? The purpose of this session is to provide an extremely thorough, historical overview of the most recent debate over the teaching and learning of mathematics, the Canadian Math Wars. Not familiar with this story? Come get caught up on what’s been going on for 5+ years in just a few hours! Time for (a lively) discussion at the end of the presentation will be strictly preserved.

Chernoff, E. J. (2013, May). Experiencing a new approach to the teaching and learning of mathematics: the instructors become the students. Workshop for the Senior Basic Education Mathematics Instructors from the Kelsey, Palliser, Wascana and Woodland Campuses of the Saskatchewan Institute of Applied Science and Technology (SIAST). SIAST Kelsey Campus, Saskatoon, Canada.

Abstract. As we are all well aware, the teaching and learning of mathematics in the province of Saskatchewan is in the midst of major change and will be for the next few years. The province’s adoption of the WNCP’s Common Curriculum Framework not only introduces new curricula (text books, etc.), but, arguably, introduces a new approach to the teaching and learning of mathematics. The purpose of this session is to provide participants with (1) an overview of the changes (2) an opportunity to experience this new approach to the teaching and learning mathematics and (3) a chance to discuss the tensions between theoretical and practical issues found in both Reform and Traditional classrooms and frustrations that have resulted from the change.
