 Mathematics of Communication and Decision-Making in Medicine
2:30pm-3:30pm

[Medical Physics Symposium]

An increasing amount of data that we encounter (not only in medicine) comes in formats that are mathematical in nature: numeric data; visual information in the form of graphs, charts and diagrams; uncertainly, expressed as percent or chance, to mention a few. How do we make sense of it?

In this talk I will explore case studies that will illustrate how basic concepts from mathematics appear in a variety of areas in health sciences. I will convince you that, in order to make sense of the data that you (will) inevitably encounter on a daily basis, you need to understand basic math really well. Only when you understand all aspects of the case you are dealing with, you will be able to communicate your ideas and thoughts effectively to your colleagues and peers.

Significant aspect of your job as a health care worker/physician/etc. will be/is communication with your patients. What you say - and how you say it - could make a big difference to them.

 Math for the Universe
9:40 am-10:50 am

[high school presentation]

What does the space that surrounds us look like? Can we determine whether it is finite or infinite? In this presentation, we will examine several case studies that will help us understand things a bit better. What is the shortest path between two points in space? How would our mundane three-dimensional existence change if we were suddenly pulled into the fourth dimension? How do mathematicians describe black holes? We will develop a reasonable scenario for time travel into the future.

[invited seminar]

Like many of us, I have worked with mathematics in a variety of ways: as researcher, teacher, supervisor, and author (of a mathematics textbook). In this lecture, I will describe how these experiences have inspired and guided me through my life as researcher in mathematics education. In particular, I plan to share my thoughts about mathematics, teaching mathematics, and its role in a modern society. I will explain why I believe that research in math education is important and highly relevant. I will discuss my research (practice-based) related to the teacher-training course for undergraduate students that I created, development of a theoretical model for the high school to university transition, and analysis of certain aspects of presentation of mathematics in calculus textbooks.

As a fundamental resource, textbooks shape the way we teach and learn mathematics. Based on examination of secondary school and university textbooks, I will attempt to describe to what extent, and how, presentation of mathematics material could contribute to creation and strengthening of students' misconceptions about concepts in calculus. Such findings raise awareness of non-obvious problems that need to be addressed in teaching. Literature search reveals that very little is known about how (and what) students learn from textbooks (or how teachers/ instructors use them). Research questions that we consider include: to what extent (and how) textbooks contribute to students,Äô misconceptions about mathematics ideas, concepts and procedures; how do textbooks balance procedural and conceptual understanding; textbook design and its correlation to learning math; quality, relevance and pedagogical value of applications; communication on mathematics content via visual means (diagrams, graphs, illustrations, etc.).

 Transition from Secondary to Tertiary Education - A Modern Rite of Passage
11:30am-1:30pm

[CLL workshop]

The passage from secondary to tertiary education is, in many ways, critical to students' success, their choice of a program of study and future career. How well students learn concepts, gain thinking skills and adopt learning strategies and then transfer these to their (new) university environment is instrumental for their success in every course that they take. Good high school students are not necessarily good and successful in university. On the other hand, some students who appear to enter university courses with lower learning skills recover quickly and are successful.

In this workshop we plan to discuss issues and identify strategies that instructors, teaching assistants, and everyone else involved with first-year students (course coordinators, student advisors, etc.) can use to help our students adjust to McMaster university learning -and other- environments.

 My Life as Researcher in Math Education
4:30-5:30pm

[invited talk]

Like many of us, I have worked with mathematics in a variety of ways: as researcher in differential geometry and mathematics education, teacher in high school and university, supervisor of undergraduate and graduate students, and as author and editor of mathematics monographs. I have talked about mathematics at various public events, and wrote about geometric ideas in art and architecture.

In this lecture, I plan to speak about how these experiences have inspired and guided me through my life as researcher in mathematics education. In particular, I will focus on my research related to the teacher-training course for undergraduate students that I created (for instance, students' understanding of the concept of a function and its graph, and analysis of teaching diaries), development of a theoretical model for the high school to university transition, and analysis of relation between students' high school mathematics knowledge and experience and their success in first-year mathematics courses.

Expectations, Challenges and Successes in Managing Large Classes
3:30-4:30pm

[invited seminar]

We all have concerns about large classes and inadequate teaching resources, but we under-utilize one of our most valuable teaching resources: our own undergraduates. Experience with undergraduate TAs at McMaster (part of which is the course "Teaching mathematics" designed by Dr Lovric) suggests both that undergraduate TAs bring a number of important advantages to the classroom, and that they count their teaching experience as one of the most valuable aspects of their own education. Besides addressing general logistics problems related to teaching large classes and discussing the ways in which we deal with them, I plan to outline the design of the "Teaching Mathematics" course, and to discuss various issues related to both the course and to students' performance as teaching assistants.

How do mathematicians model our Universe? What are the most important features of their models, and to what extent are they realistic?

We will present several concepts - including dimension, curvature and metric - that will help us understand things a bit better. Using the notion of space-time, we will explain how mathematicians think of phenimena such as black holes. Are wormholes matter of science fiction, or can they possibly exist? Can we make time travel work?

 Suggestion For A Theoretical Model For Secondary-Tertiary Transition In Mathematics
TBA (will appear in conference program)

[ICTM3 - Third International Conference on Teaching of Mathematics]

Abstract: The transition ('gap') between secondary and tertiary education in mathematics is a complex phenomenon covering a vast array of problems and issues. Although there is evidence of similar gaps in other disciplines in science and beyond, it seems that the transition in mathematics is by far the most serious and the most problematic. Based on certain anthropological notions, we suggest a model for the secondary-tertiary transition in mathematics. Although we focus on the area of mathematics, and on transition between a secondary institution and university (and, to a lesser degree, college), the model could be applied, with minor modifications, not only to other transitions in mathematics (primary-middle, primary-secondary, etc.) but to other areas as well. This model provides a useful lens through which we can examine the process of transition from secondary to tertiary mathematics, and also offer ways of improving present strategies and suggest new ones.

Mathematics - Can't Live With It, Can't Live Without It
5:15-6:15pm

[Department of Mathematics Invited Colloquium]

What is the place of mathematics in modern society? The range of applications of mathematics has never been as broad as it is today. Paradoxically perhaps, the number of people who are interested, or say they are good at math, or decide to study math has been
dwindling ... How important is it to know mathematics? Examination of the role and politics of mathematics and an analysis of issues in teaching and learning mathematics will lead us to fundamental questions, including the one which, quite possibly, cannot be completely resolved: what is mathematics?

 Stories About Infinity
time: 10:30-11:30am

[McMaster Accelerated Students Workshop]

Infinity has many faces. Sometimes, we perceive it as a number larger than all numbers. For indigenous people of Australia and New Guinea, infinity begins at six. For the Moors - creators of the most beautiful mosaics the world has ever seen - infinity was in a repetition of a single artistic motif. Infinity is eternity, divinity, love, death ... Modern mathematicians have embraced
infinity as one embraces a good friend; but a few have contemplated suicide rather than being forced to face it. Georg Cantor, early explorer of infinity, died in a mental institution. What exactly drove him to insanity? Does infinity really exist? If so, what is it? Where can we find it? Is our universe large enough to encompass infinity?

[Canadian Perspectives Lecture Series, University of Toronto, Mississauga]

There is so much to look at and admire in Alhambra Palace (Granada, Spain) - exquisite rooms, decorated with stone and wood carvings, finest ornaments, and calligraphy; night sky represented in ceilings built of thousands of pieces of wood; gardens, courtyards and fountains; monuments, towers, archways - the list is endless. Quite possibly, an immense wealth of ornamental patterns, friezes, mosaics, star designs, and brickwork motifs tops the list. Among those, mosaics are perhaps the most interesting and the most intriguing.

Scientists and artists working in the Islamic world pushed geometry to its limits, creating patterns and configurations whose sophistication has never been surpassed. Investigating numerous possibilities, based on experience and long tradition, builders of mosaics in the Alhambra created them all in the sense of the mathematics theorem on the classification of plane crystallographic groups (or wallpaper patterns). Mosaics are an invitation for a 'dynamic' experience, different from enjoying a picture of a landscape. This presentation suggests the use of a vocabulary from geometry to express some of our visual experiences.

1, 1, 2, 3, 5, 8, 13, 21 caught you!

Were you staring at those numbers trying to make some sense of them? Have you guessed the next number in the sequence?

Mathematics is everywhere around us. Whether it's guessing the tax on the purchase we are about to make, calculating our body mass index, reading the sports stats page in a newspaper, figuring out how much paint we should buy to paint the bedrooms or trying to solve that Sudoku puzzle ­ we cannot avoid using numbers.

This lecture will suggest ways of thinking about mathematics that we can all embrace and apply in our everyday situations. Although there seems to be just too much math to learn, Professor Lovric will convince you that a few basic concepts will significantly enhance your understanding of a whole variety of problems that are mathematical in nature.

The math that we need in our lives is ­ quite often ­ not what we have been taught in school. Professor Lovric will encourage participants to think about math in a new way ­ not as an object of fear and frustration (or bad memories) ­ but as a useful and creative new friend, that will help us make sense of many things.

and the answer to that math teaser is 34 each number is the sum of the 2 numbers preceding it!

This is a free public lecture. All are welcome!

For the Moors - creators of exquisite mosaics and patterns whose sophistication has never been surpassed - infinity was a repetition of a single artistic motif. Infinity is eternity, divinity, love, madness ...

In this lecture, I will touch upon many amazing aspects of infinity. I will explain straightforward concepts, developed by mathematician Georg Cantor, that form the basis of our modern understanding of infinity. Cantor had the courage to look infinity into its eyes - and what he saw deeply shocked him. 'I see it, but I do not believe it,' he exclaimed as he witnessed his discoveries, unleashed, shaking mathematics to its core and changing it forever. Cantor died in a mental institution. What drove him to insanity?

Does infinity really exist? If so, where can we find it? Is our universe large enough to encompass infinity?

 Art, Architecture and Mathematics
9:30-11am

[High School Mathematics Presentation]

Mathematics (and sciences in general) have always been a source of inspiration to artists and architects. The direction also reverses ... ideas that first appeared in literature, or art, later found their way into physics and mathematics theories (for instance, the question about existence of parallel realities/universes has been raised many centuries ago!).

We will explore several case studies. Concepts of space-time and fourth dimension found their way into art (Picasso, Braque, Dali), and architecture (Arc de la Defense in Paris). Ndebele African art patterns reveal sophisticated symmetric patterns. Architects use geometry in design (Bilbao Guggenheim Museum, Esplanade Performing Arts Centre in Singapore and Sydney Opera House).

 Mysteries of Infinity
3:45pm-4:45pm

[Lecture for high school students - same topic as the public lecture scheduled for 19 October]

Infinity has many faces. Sometimes, we perceive it as a "number" larger than all numbers. For indigenous people of Australia and New Guinea, infinity begins at seven. For the Moors - creators of exquisite mosaics and patterns whose sophistication has never been surpassed - infinity was a repetition of a single artistic motif. Infinity is eternity, divinity, love, madness ...

In this lecture, I will touch upon many amazing aspects of infinity. I will explain straightforward concepts, developed by mathematician Georg Cantor, that form the basis of our modern understanding of infinity. Cantor had the courage to look infinity into its eyes - and what he saw deeply shocked him. 'I see it, but I do not believe it,' he exclaimed as he witnessed his discoveries, unleashed, shaking mathematics to its core and changing it forever. Cantor died in a mental institution. What drove him to insanity?

Does infinity really exist? If so, where can we find it? Is our universe large enough to encompass infinity? Could our space have infinitely many dimensions?

What does the space that surrounds us look like? Are we able to see it, feel it, touch it? Is it finite or infinite?

We do not pretend to know the answers. But we propose to examine several case studies that will help us understand things a bit better. What is the shortest path between two points in space? How would our mundane three-dimensional existence change if we were suddenly pulled into the fourth dimension?

Concept of the space-time and metric. How do mathematicians describe black holes? We will develop a reasonable scenario for time travel into the future.

 "Learning How to Teach and Learn Mathematics: 'Teaching Mathematics' Course at McMaster University"
.

[1st Africa Regional Congress of the International Commission on Mathematical Instruction ]

The course "Teaching Mathematics" has been designed in an attempt to improve the quality of instruction delivered by undergraduate teaching assistants in mathematics at McMaster University. Problems traditionally experienced by our teaching assistants range from a lack of knowledge of mathematics content, and lack of guidance by lecturers and course coordinators, to rudimentary teaching skills without opportunities for improvement, to low motivation, and inadequate preparation for a tutorial session.

A group of undergraduate students are enrolled in the "Teaching Mathematics" course and concurrently work as teaching assistants for a first-year calculus course. In other words, they are both teachers and learners at the same time. A framework for the "Teaching Mathematics" project is that of a learning partnership on several levels: partnership between undergraduate students, i.e., between undergraduate teaching assistants, and between undergraduate teaching assistants and students in their tutorial groups. It is also a learning partnership between the "Teaching Mathematics" course instructor and the students (in the "Teaching Mathematics" course). Such framework is an echo of the fact that education must be an active and inspired two-way communication.

In this session, I plan to outline the design of the "Teaching Mathematics" course, and to discuss various issues related to both the course and to my students' performance as teaching assistants. Teaching assistants work on improving their written and oral communications skills through writing about mathematics, conducting tutorial sessions and through one-on-one sessions with their students during office hours. In "Teaching Mathematics" sessions, we discuss and analyze elements that constitute good teaching practice - especially preparation (knowledge of mathematics) and communication. By reading and criticizing journal and newspaper articles and books we get introduced to theoretical aspects of teaching, and, in particular, teaching mathematics. By learning how to teach mathematics we also learn how to learn mathematics - certainly, a very valuable asset - especially for those students who plan to major in mathematics.

"Teaching Mathematics" course provided me with an opportunity to constantly monitor the work of my students - my teaching assistants (we used evaluations, self-evaluations and personal interviews). I have collected valuable data and information that I plan to discuss in my session.

 "Mathematics Background Survey ­ An Insight Into Students' Preparation for University Mathematics Courses"
.

[1st Africa Regional Congress of the International Commission on Mathematical Instruction ]

Transition between secondary and tertiary education in mathematics is a complex phenomenon covering a vast array of problems and issues. Although there is evidence of existence of similar issues in other disciplines in science and beyond, it seems that the transition in mathematics is by far the most serious and the most problematic. In spite of all efforts and energy ventured into the pre-tertiary mathematics education, the knowledge and skills of incoming university students are far from satisfactory. Students coming to tertiary institutions are more numerous and more diverse; they have different and often unclear views of mathematics and its role in their future career. Their views echo a seemingly contradictory (but, unfortunately, true) fact that, although the importance of acquiring mathematical skills has been rising, the lack of appreciation of mathematics on the part of the public is evident. Curricular changes may also have influenced characteristics of incoming students. University teachers may largely be unaware of or unwilling to accept the magnitude of these changes. Moreover, the amount of research on mathematics education at the tertiary level is still modest. Inquiry into both social and cognitive backgrounds of students may provide an insight into how the two factors relate to and affect one another.

The aim of this talk is to present partial results of a survey ('Mathematics Background Survey') of incoming university students (future majors in science), that has been conducted at McMaster University since 2001. The survey has two parts, roughly described as 'narrative' and 'mathematics.' Besides inquiring about basic demographic data, the 'narrative' part asks students to describe their experiences with high school mathematics and their expectations about the university mathematics courses. The 'mathematics' part aims to identify students' strengths and weaknesses in the number of areas that are essential for their success in university mathematics courses. Information on students' experiences with mathematics in high school is being examined for correlations with their success in their first-year mathematics course. Information on students' background preparation and experience in mathematics should be very valuable to university faculty, some of whom are not aware of the magnitude of changes in the incoming student population.

 "Mathematics and Beauty in Islamic Architecture"
11am-noon

[Subtle Technologies Conference 27-29 May]

There is much to see and admire in the Alhambra Palace: exquisite rooms, decorated with stone and wood carvings, finest ornaments, and calligraphy; night sky represented in ceilings built of thousands of pieces of wood; gardens, courtyards and fountains; monuments, towers, archways - the list is endless. Quite possibly, an immense wealth of ornamental patterns, friezes, mosaics, star designs, and brickwork motifs tops the list. Among those, mosaics are perhaps the most interesting and the most intriguing. Scientists and artists working in the Islamic world pushed geometry to its limits, creating patterns and configurations whose sophistication has never been surpassed. Investigating numerous possibilities, based on experience and long tradition, builders of mosaics in the Alhambra created them all ? in the sense of the mathematics theorem on the classification of plane crystallographic groups (or wallpaper patterns). Mosaics are an invitation for a 'dynamic' experience, different from enjoying a picture of a landscape. Our eye is not able to focus on one location; there is no centre, no boundary and no preferred direction. This presentation suggests the use of a vocabulary from geometry to express some of our visual experiences.

Interdisciplinary component of the Mathematics course taught in the Arts and Science Programme at McMaster University is implemented in several ways, varying in depth, width and level of involvement of other courses. Of a number of issues related to the course, this paper uses instructors' experience and examples of students' writing to discuss the features of the narrative in mathematics. Used as a vehicle to enhance understanding of mathematics and to build and improve research and communication skills, good writing is a key to a successful and productive interdisciplinary mathematics course.

Modern mathematicians have embraced
infinity as one embraces a good friend; but a few have contemplated suicide rather than being forced to face it. Georg Cantor, early explorer of infinity, died in a mental institution. What exactly drove him to insanity? Does infinity really exist? If so, what is it? Where can we find it? Is our universe large enough to encompass infinity?

 "Using Undergraduate TAs in Large and Online Classes"
2:30pm-4:30pm [CLL Seminar, Dick Day, McMaster University; Arshad Ahmad, Concordia University, Miroslav Lovric, McMaster University]

We all have concerns about large classes and inadequate teaching resources, but we underutilize one of our most valuable teaching resources: our own undergraduates. Experience with undergraduate TAs at McMaster suggests both that undergraduate TAs bring a number of important advantages to the classroom, and that they count their teaching experience as one of the most valuable aspects of their own education. Dick will be describing some of his experiences with undergraduate TAs.

Arshad's experience with an elective course on Personal Finance at Concordia University has been focused on the model of distributed expertise and multiple tools for learning. This course has grown into one of the largest in Canada, and enjoys very low attrition rates for one important reason: The TA's. Their vital role, motivation to continue and input in continuous development will be highlighted.

Miroslav has learned a great deal about undergraduate teachers from teaching his "Teaching Mathematics" course, and has gained valuable insights from a variety of sources. Recently, the Department promoted a few of their most successful TAs into 'Head TAs,' giving them additional duties and more responsibility. How are they coping with the challenges their new job presents? In the past several years, we have witnessed an increase in a number of students interested in teaching careers. Their undergraduate teaching jobs provide them with a set of skills that will help them both in their studies and later, when they start teaching in high school or in university.

An increasing amount of data that we encounter (not only in medicine) comes in formats that are mathematical in nature: numeric data; visual information in the form of graphs, charts and diagrams; uncertainly, expressed as percent or chance, to mention a few. How do we make sense of it?

In this talk I will explore case studies that will illustrate how basic concepts from mathematics appear in a variety of areas in health sciences. I will convince you that, in order to make sense of the data that you (will) inevitably encounter on a daily basis, you need to understand basic math really well. Only when you understand all aspects of the case you are dealing with, you will be able to communicate your ideas and thoughts effectively to your colleagues and peers.

Abstract: This study explores the changes in knowledge of certain areas of mathematics and various skill levels of students entering first year mathematics courses, and examines their relationship to students' success in first-year university mathematics courses. Of particular interest to us are students who appear to enter university mathematics courses with low technical skills in mathematics, yet recover quickly and are successful. This exploratory study examines data collected over a three-year period from students in both the 'old' and 'new' Ontario curricula. The main focus of the current report is the difference between the incoming knowledge and skills and the performance in the first year mathematics course of these two groups of students.

[Engineering and Science Olympics lecture]

Abstract: Today, millions of bits of sensitive and confidential information need to be sent over computers daily. In order to ensure security, the information must be coded ­ hence the permanent need for secure, hard-to-break codes. Presently accepted standard, the so-called RSA encryption code uses modular arithmetics. Learning how the information is coded will help us understand why is the code so hard to break. Next, we learn about error-detecting and error-correcting codes. After presenting basics, we will explore how information is coded onto music and video disks (CD, DVD). As another application of modular arithmetics, we will explore the way colour works in computers. If time permits, we will discuss mathematics of data compression, in particular the way it is applied to storing millions of cards with fingerprints. Finally, at the end of the lecture we will mention Goldbach's conjecture, an old, but still unsolved mathematics problem.

 " ... Hold Infinity in the Palm of Your Hand, and Eternity in an Hour" (Science in the City lecture series)
7:00pm-8:00pm

Infinity has many faces. Sometimes, we perceive it as a "number" larger than all numbers. For indigenous people of Australia and New Guinea, infinity begins at seven. Infinity for Van Gogh was a vast, unending plane, on which imagination is given free rein. For the Moors - creators of exquisite mosaics and patterns whose sophistication has never been surpassed - infinity was a repetition of a single artistic motif. Infinity is eternity, divinity, love, madness ...

In this lecture, I plan to present a sketch of a cultural history of infinity, spanning thousands of years. I will explain amazingly straightforward concepts, developed by mathematician Georg Cantor, that form the basis of our modern understanding of infinity. Cantor had the courage to look infinity into its eyes - and what he saw deeply shocked him. 'I see it, but I do not believe it,' he exclaimed as he witnessed his discoveries, unleashed, shaking mathematics to its core and changing it forever.

Cantor died in a mental institution. What drove him to insanity?

Does infinity really exist? If so, where can we find it? Is our universe large enough to encompass infinity?

Although no mathematics background is required, certain amount of courage is expected from those in attendance. This lecture might threaten, and possibly change, some of our most cherished notions about life and the world we live in.

It might take all of eternity to reach infinity. But sometimes, infinity gets so close to us, that, as if in a dream, we feel that we can hold it in the palm of our hand.

"Jumping over Fire: Some Hot Issues in the Transition from Secondary to Tertiary Education"
12:00noon-1:00pm The 'gap' between the secondary and the tertiary education in mathematics is a complex phenomenon covering a vast array of issues. Rather than speaking in general terms, I plan to focus on specific problems that we (at McMaster University) have encountered, and on our attempts at dealing with them. I will report on the joint work with Ann Kajander (Lakehead University), on our study of the Mathematics Background Questionnaire. Besides getting a fairly decent snapshot of mathematics knowledge, the survey provided us with valuable information on our students' high school experiences and expectations of their university mathematics courses. Moreover, I will talk about the project 'Transition from secondary to tertiary education in mathematics - strategies that work' that we have been involved with. This project deals with the transition issues in a more global context.

 "Smart Numbers" (Fireball Show for high school students)
11:00-11:30am FULL

You bought a phone card, and are making a phone call: dial the number, and punch in the card number. The voice on the other side tell you that the card number you entered is incorrect. Then you realized that you indeed made a mistake - you switched the last two digits. How did they know?

Your CD produces a prefect sound even though your cat just walked over it, its feet wet and muddy ...

A brief introduction into the exciting world of error-correcting codes.

"Convergence of Media: Textbooks and Internet - What's the Difference?"
10:30am-11:00am I plan to report on my initial investigation into the most recent evolution of textbooks. Although I plan to present a case study of textbooks in mathematics, my discussion will cross the border into other areas. By contrasting old and new textbooks, and by comparing new textbooks to Internet sites that offer instruction, valuable conclusions on present trends in learning can be drawn. I will argue that, by abandoning 'old' textbook style, we might be in danger of abandoning important methods and ideas on teaching and learning. The conclusion of the talk will offer a creative compromise between paper and internet.

 "Have Eyes to Wonder, But Lacks Tongues to Praise"
7:30pm-8:30pm The aim of my presentation is to suggest a possibly new way of looking at objects of art that possess certain geometric features, and to provide a vocabulary to communicate those ideas. Based mostly, but not exclusively, on concepts from Euclidean geometry, this new vocabulary might help us verbalize why we perceive something as beautiful. Rather than replacing any part of our visual experience, geometry will help us make it richer. A case study of symmetries of mosaics from the Alhambra Palace in Granada, Spain, will be discussed. Mosaics present important clues in understanding the space we live in ... what do they tell us?

 "Where do we Really Live?"
7:00pm-8:00pm What does the space that surrounds us look like? Are we able to see it, feel it, touch it? Is it finite or infinite? We do not pretend to know the answers. But we propose to examine several case studies that will help us understand things a bit better. What is the shortest path between two points in space? How would our mundane three-dimensional existence change if we were suddenly pulled into the fourth dimension? Do wormholes really exist? We will develop a reasonable scenario for time travel into the future.
