Title: Catalyzing Change: Identity, Agency, Positionality, and Equitable Instructional Practices

Abstract: This session makes connections between equitable instructional practices and identity, agency and positionality. Specifically, the session uses a vignette to examine how high cognitively demanding task provides opportunities to engage learners in meaning discourse, positioning learners as mathematically competent. The session uses mathematical discourse community as a framework for connecting mathematics norms of discourse to identity and agency. While this session highlights Catalyzing Change for High School Mathematics, the discussions of teaching practices that cultivate identity, agency, and positionality is appropriate for all educators.

Title: Supporting Mathematics Teachers鈥� Sensemaking through Video Feedback: Diagnosing Classroom Troubles for More Productive Responses

Abstract: Mathematics educators exhort teachers to let students work together so they can engage ideas in their own language and support their sensemaking. Yet, when teachers hand math off to students, new social dynamics come into play. Adding to the complexity, high school students they are often very skilled at what aspects of their interactions they allow teachers to see, making it difficult for teachers to 鈥渞ead鈥� the groups. In this study, the Project SIGMa research team partnered with experienced secondary mathematics teachers to design a video-based formative feedback (VFF) coaching cycle that supported new insights into the social dynamics that arise when students work on mathematics together. The teachers often developed new understandings about what was (and was not) working in their classrooms. By enhancing the information teachers have access to, our video feedback allowed teachers to make better diagnoses of classroom troubles and, in turn, identify more effective strategies for addressing them. In this talk, I give several examples of insights teachers developed through our video coaching process. I discuss what these examples tell us about experienced mathematics teachers鈥� learning and the implications for instructional coaching specifically and teacher education in general.

Title: Acknowledgement as a Requirement for Equity Work within the Mathematics Classroom

Abstract: This talk centers around Acknowledgement as a precursor to any form of equity work within the mathematics classroom. How can we foster equity, visibility, and validity within our classrooms if we, as teachers, have not done the work required to critically examine how our identities, privileges, and comfort continue to render some of our students invisible. In this talk, we will discuss what acknowledgment looks like, why it is necessary, why comfort is the enemy of progress, and why if we don't start consistently and critically questioning our work that those students who are invisible to us will remain so.

Title: Helping students learn mathematics through 鈥渓ooking back鈥�

Abstract: Looking back is presented as the last step in Polya鈥檚 4-step problem solving process, and often receives much less attention than other steps in problem solving. In this talk, I will highlight the importance of 鈥渓ooking back鈥� not as the end of problem solving, but a starting point of helping students鈥� learn mathematics and develop their habits of mind. Specifications of 鈥渓ooking back鈥� show its importance for developing effective classroom instruction and for reflecting on practices in mathematics teacher preparation and professional development.

Title: Instructional Sequences, Task Authoring, and Mathematical Abstractions: How Kicking a Soccer Ball Unleashed my Creative Potential

Abstract: In this talk, I describe the notion of instructional sequence as a guiding principle in teachers鈥� curriculum practices. Instructional sequences emanate from conjectures about how to develop students鈥� thinking, and are not based strictly on the logic of the discipline. They begin with a low-entry high-ceiling task that elicits thinking around key ideas. These core ideas are then revisited and refined, leading ultimately to tasks that emphasize formalization and fluency. I describe how task authoring in the development of instructional sequences is associated with learning and local capacity building. I situate the talk in the context of using a video of me kicking a soccer ball as the basis of the instructional sequence; creating tasks from the video involved processes of mathematical abstraction and transformation of metric spaces. Authoring these tasks forced me to think about how students might wrestle with key mathematical ideas, and extended my own thinking and capacities.

Title: Developing mental images of key mathematical concepts: The role of interactive dynamic technology

Abstract: Understanding a mathematical concept involves creating a mental image of that concept. An interactive discussion will focus on a technology-leveraged approach for helping students developing develop robust conceptual structures for key mathematical ideas. Interacting with the files allows students to build a dynamic 鈥渕ovie clip鈥� of features of the concept that can become the basis for understanding. The discussion will include examples of interactive 鈥渁ction/consequence鈥� apps that lay the foundation for concepts in the middle grades and expand them into high school using with carefully designed tasks to move learning forward. In particular, the technology can help students confront misconceptions, identified as typical in the research, as they learn to make sense of mathematical ideas.

Title: The Calculus Project: 听Re-envisioning the Brilliance of African American students in Mathematics

Abstract: The Calculus Project (TCP) was conceived in 2009 in one schoolhouse 鈥� Brookline High School in Massachusetts 鈥� in response to:

1. the historical and ongoing dismal data at Brookline High, replicated nationally, on the math achievement of African American students;
2. the predictive power of success in high-level mathematics in high school 鈥� particularly calculus 鈥� on overall graduation rates from college, and increased enrollment and success in the STEM disciplines at college;
3. the very positive prospects for employment in the STEM professions in our nation where millions of STEM positions are going unfilled, and where there are continued low numbers of STEM professionals of color.

TCP is defined by its comprehensiveness, high expectations, cultural sensitivity and commitment to sustainability.听 Calculus Project programs begin in the middle schools and expand to high schools over a five-year period.听 TCP provides the kind of services and supports to historically underachieving students that more advantaged families and communities provide to their children.听 These include: 听1) The Summer Academy; 2) The After-School Academic Center; 3) The Pride Curriculum; 4) Field trips to STEM worksites; 5) Peer-teaching; and 6) A class grouping strategy that brings together critical masses of historically underachieving students in high level math classes.听 In June 2014, the first cohort of TCP students graduated from Brookline High School and now attend the most competitive colleges and universities in the country, such as MIT, NYU, Duke, Emory and Center College.听 Today, all of them are seniors in college and many of them will graduate with degrees in the STEM disciplines.

Title: Stimulating Mathematical Curiosity and Awe with Curriculum

Abstract: To address persistent student disinterest and lack of engagement听in mathematics, this talk will听explore how secondary听mathematics teachers can plan and enact learning听experiences that spur student curiosity, captivate students with听complex mathematical content, and compel students to听engage and persevere. I will听introduce a framework that听interprets mathematics lessons as stories, which supports the听design of lessons that offer听dramatic suspense and resolution. I will听present a mathematical lesson designed and enacted by an听elementary teacher using this framework. Then I will share how听this framework can make sense of a compelling moment in an听algebra course.听By viewing mathematical content in narrative听terms (as opposed to focusing on contextual word-problem as听narrative), the audience will be invited to consider how to design听mathematical experiences that emotionally moved student and听teachers and compel them to engage.

Speaker: Professor听Marilyn Strutchens, Auburn University

Title: Equitable teaching strategies - the Keys to students鈥� mathematical reasoning and sense making

Abstract: The discussion will focus on strategies that have been shown to help each and every student reason听and make sense of mathematics.听 We will examine vignettes, video clips, and student responses to problems situated in a variety of contexts.听 At least nine equitable teaching strategies will be discussed.

Speaker: Professor Janine Remillard, University of Pennsylvania

Title: Increasing Access to Mathematics through Locally Relevant Curriculum

Title: Exploding Dots: Uniting elements of the K-12 curriculum鈥揳nd beyond鈥搃n one fell swoop!

Abstract: Here is a story that isn't true. When I was a young child I invented a machine (not true) that was nothing more than a series of boxes that could hold dots. And these dots would, upon certain actions, explode. And with this machine (in this non-true story) I realized that I could explain true things! I could explain all the mathematics of arithmetic I learnt in grade school (true), all the of the polynomial algebra I was to learn in high-school (true), elements of calculus and number theory I was to learn in university (true), and explore unanswered research questions mathematicians are studying today (also true)!

Come join us as we explore the power of an astounding simple mathematical construct pushed to the max. Experience deep creative discovery first-hand and true joyous mathematics doing. And bring pencil and paper. This session will have you jotting down notes and playing with lots of ideas.

Title: Improving Learning and Engagement in Algebra through Comparison and Explanation of Multiple Strategies

Abstract: Over the past decade or so, my research has explored the ways that comparison and explanation of multiple strategies can be used in mathematics classrooms to improve students鈥� learning and engagement. After a brief introduction to the theory and research that supports this approach, this talk looks more specifically at teaching practices and curriculum materials that leverage comparison and explanation of multiple strategies - particularly in algebra but more generally throughout middle and high school mathematics.

Speaker: Yvonne Lai (University of Nebraska)

Title: Knowledge and tasks connecting elementary, secondary, and disciplinary mathematics

Abstract: A well-prepared teacher should be able to help her students see mathematics as ideas that develop over time. Mathematics courses designed specifically for prospective secondary teachers aim for prospective teachers to see and find connections across elementary, secondary, and disciplinary mathematics, and beyond that to be able to use those connections in their future teaching. While there is broad agreement with these aims, there is also little consensus around how to carry them out. Two challenges in meeting these aims are identifying content that lends itself to such connections and designing tasks that can be used to engage with that content. In this talk, I will propose a few examples of content and tasks, and discuss what may make them useful. I will then invite the audience to contribute ways they have used their teaching to meet the challenge of identifying content and designing tasks for the purpose of connecting elementary, secondary, and disciplinary mathematics.

Title: How Evidence Centered Design Can Support Improved Teaching and Increased Learning of Mathematics

Abstract: In a climate of greater and greater calls for information by which to make decisions about instruction, program, hiring, and support, it is reasonable- -- even necessary -- to understand the process by which such information is created. Evidence Centered Design (ECD) and its various applications to educational tool design can provide a map in an otherwise confounding labyrinth of trial and error to determine 鈥渨hat works.鈥滻n his presentation, Doug Sovde, Director of Mathematics Design and Development at Parcc Inc. will describe how ECD has been the foundational design approach for tools ranging from the PARCC summative test to professional learning around instructional leadership and provide a process by which educators can apply ECD in their own work.

Title: What Every Algebra Teacher Needs to Know about the Foundations of Algebra

Abstract: We all know what a successful trajectory through algebra looks like, but unfortunately many students do not experience it. Why do so many struggle with algebra? And what can we do about it? In this talk, we will begin with a quick tour of the cognitive foundations of numbers and operations and the development of the concepts that lay the foundations for algebra. Then we will review some evidence that students who are behind at entry to algebra are missing some of the fundamental building blocks from their earliest years, contrary to the popular notion that students are just a few years behind in their mathematical development. Then we will discuss some strategies to help struggling middle and high school students fill in these gaps.

Speaker: Dr. Sarah Sword, Educational Development Center

Title: How Square is a Rectangle?

Abstract: Mathematical Habits of Mind are the specialized ways of approaching mathematical problems and thinking about mathematical concepts that resemble the ways employed by mathematicians. These habits are not about particular definitions, theorems, or algorithms that one might find in a textbook; instead, they鈥檙e about the thinking, mental habits, and research techniques that mathematicians employ to develop such definitions, theorems, or algorithms. Some examples of MHoM follow:
听

• Discovering the structure that is not apparent at first by experimenting and seeking regularity and/or coherence.
• Choosing a useful representation鈥攐r purposefully toggling among various representations鈥攐f a mathematical concept or object.
• Purposefully transforming and/or interpreting algebraic expressions鈥攅.g., rewriting听x²听- 6x听+10 as (x听- 3)²听+ 1 to reveal its minimum value.

In this session, we will begin with an exploration of how to measure the 鈥渟quareness鈥� of rectangles: the degree to which a particular rectangle is close to (or far from) being a square. We will use this geometric question to explore the habit of mind of 鈥渄iscovering structure that is not apparent at first,鈥� which is closely related to Common Core State Standard for Mathematical Practice MP7, 鈥淟ook for and make use of structure.鈥�

Title: The mathematical education of secondary school teachers in Qu茅bec: comments from a mathematician鈥檚 perspective

Abstract: In this talk, I wish to reflect on the mathematical education of secondary school teachers. I will first offer comments on the role of mathematicians in teacher education, inspired both by my personal experience as well as by actions of the International Commission on Mathematical Instruction (ICMI). I will also discuss a few general issues related to the preparation and development of mathematics teachers, based in part on the outcomes from a Study organized on that theme by ICMI.

In the next part of my talk, I will present the context for the preparation of schoolteachers in Canada, and more specifically in the province of Qu茅bec (education being of provincial jurisdiction in Canada). Comments will be offered about the two main models for teacher education in Canada: the so-called consecutive model, where the pedagogical content is addressed after a first university degree, and the concurrent model, where the choice of a teacher education program is made upon entering university.

I will then examine some of the themes around which the mathematics preparation of schoolteachers is articulated at my university. I will stress in particular the context of mathematics courses specifically designed for teachers offered by my department and survey the main themes discussed. Finally, examples will be given of mathematical topics presented in these courses, mostly in connection with a course on the history of mathematics for prospective secondary school teachers.

Title: Guiding Principles for the Implementation of the Common Core State Standards in Mathematics

Abstract: The Common Core State Standards in Mathematics (CCSSM) are not about how to teach mathematics; rather, they are about the mathematics that should be taught. However, the mathematics depicted in the CCSSM demands particular ways of teaching, for this 鈥渕athematics鈥� includes not only subject matter鈥攃ollections of definitions, theorems, proofs, problems and their solutions, algorithms, etc.鈥攂ut also ways of thinking. Teachers must be given ample opportunities to develop this new view of mathematics and mathematics teaching, and be equipped with the pedagogical content knowledge to bring students to uncover mathematical ideas. The purpose of this talk is to discuss guiding principles for the development and acquisition of both this new view of mathematics and the pedagogical content knowledge necessary to bring students to acquire and internalize mathematical ideas.
