These CWIC sessions are available throughout the Institute, are approximately one hour long, and delegates can attend as many or as few as they can fit into their timetable. This is your Conference Within a Conference!!...a second event running parallel to the longer 10 hour courses. ...more in keeping with the format of 'traditional' conferences. Their availability will be published onsite, and they are available for as many people can fit into the session room!.......they are a snapshot, sampler, teaser, or discussion point.....make sure you don't miss them!

Conference within a Conference [CwiC] Session



TTLI 04 Forum

Are we satisfied with what happens in our classrooms? What can we do to make a change?

Bruce Dixon & friends

The inaugural TTLI Forum: a moderated, interactive discussion to provide everyone with an opportunity to reflect on their learning at the Institute and how you may influence change in your own schools.

CwiC 1: Using MicroWorlds and Geometer together

Mark Chapple

Combing MicroWorlds and Geometer Sketchpad to investigate and build upon previous learning is a powerful way to help students understand geometry. This session will show you ways of linking the two to improve students learning.

CwiC 2: MicroWorlds and Patterns

Mark Chapple

Using MicroWorlds to fun create patterns that involve geometry, algebra, angles and thinking skills. An overview of the sort of geometrics patterns that can be made ranging from the simple to the complex.

CwiC 3: Geometer Sketchpad Hooks and fun stuff

Mark Chapple

Whilst Geometer Sketchpad can be used for functions and a range of investigations there are some fun items that can be used to interest students and get them involved and wanting to know more about the software. Angles, creativity and thinking skills are required by students.

CwiC 4: MicroWorlds Art

Mark Chapple

Jackson Pollock and the cubists beware. MicroWorlds has arrived. Make fun art with MicroWorlds and improve your maths at the same time.

CwiC 5: Effective use of PowerPoint in the Mathematics Classroom 

Nils Ahbel

PowerPoint can be used to present complex concepts in a dynamic way that makes it easier for students to learn.  This session is not about bells and whistles, it is about improving the way we teach and the way students learn.  Over 50 PowerPoint presentations are available on-line.

CwiC 6: Rethinking Regression: Is There a << Better Way >> to Teach Curve-Fitting?

Nils Ahbel

When using the built-in regression tools of graphics calculators students are doing little more that matching shapes of a scatterplot to the shape of a toolkit function graph; the calculator does the rest of the "thinking".  There are a limited number of regression tools, but an infinite number of possible functions.  In this session an approach will be explored in which students decide which function or transformation/composition of functions best fits the scatterplot and adjusts each function parameter.

CwiC 7: The Mathematics of Bridges

Mary Bourassa

Bridges can be very beautiful structures and the engineering behind them lends itself well to many topics in mathematics. This session will take a brief look at the history of bridges and see how their shapes can be used in mathematical modelling and other applications.

CwiC 8: Catch the Wave

Mary Bourassa

Come try out various ways of getting sinusoidal data using a CBR or CBL2 with a graphing calculator or TI InterActive! and the Internet.  Handouts will be provided taking you through the modelling process and some extension questions.  If you can walk in circles and make music then this session is for you.  (BYOBB - bring your own beer bottle!)

CwiC 9: Peanut Software - It Doesn't Get Any Better Than This. Or Cheaper.

Tom Seidenberg

This session will present some excellent public domain software (graphing, geometry, data analysis) that can be downloaded from the Internet.

CwiC 10: It's a Long Way from Exeter , NH , USA to Melbourne , Australia - But Exactly How Long?

Tom Seidenberg

This session will present a series of problems that develop a method for answering this question without relying on those formulas you learned (and subsequently forgot) in trigonometry. It all depends on the Pythagorean Theorem and right triangle trigonometry.

CwiC 11: Algebra Through Calculus IN MOTION

Audrey Weeks

Discover how visual images and dynamic computer animations of problems throughout the curriculum (via Geometer Sketchpad 4) enliven mathematics concepts, raise understanding, promote reasoning, and enhance student performance at all levels. Exciting and adaptable animations will be demonstrated for a wide assortment of topics from pre-algebra through calculus.”

CwiC 12: Pi – “Food” for Thought and Celebration


Audrey Weeks

A PowerPoint collection of information on Pi will be shared with attendees for convenient and meaningful use in the classroom, along with suggestions for celebrating Pi-Day, 3/14.

CwiC 13: The Golden Ratio – a Multidisciplinary Excursion

Audrey Weeks

Explore this fascinating number in sculpture, painting, architecture, biology, nature and geometry throughout history. A PowerPoint presentation of this collection of information will be shared with attendees for convenient use in the classroom.

CwiC 14: CyberChallenge - an adaptable PowerPoint quiz show style game board

Audrey Weeks

See how PowerPoint can be used to build ‘an interactive game board’ in which new categories and questions easily can be added by students or teachers. Great for spicing up review days, for student contests, or student projects creating a legacy of games archived for future classes.

CwiC 15: Some Eclectic Secondary Problems

Ira Nirenberg

Looking for some interesting Pre Calculus problems to share with your students? Well, you must be in the right place! Explore astronomical concepts with parametric equations and an interesting activity from the 15th century dealing with optimization. Great set of Worksheets!

CwiC 16: Linear Regression — How to Derive the Basic Equations — Simply!

Ira Nirenberg

What exactly is linear regression and how is it done? Find out how to explain to your students what their TI is doing! In the process, we’ll make use of a nice bit of mathematics that second year algebra students will understand.

CwiC 17: CAS [Computer Algebra Systems] for mathematical understanding.

Peter Fox

Learn how to use a computer algebra system and how to increase student understanding. The Voyage 200 will be used (TI-InterActive optional) to demonstrate how students can gain a greater understanding and ability to solve and generalise mathematical problems. Sample examination questions will be provided to demonstrate how to ask 'traditional style questions' that still examine student understanding while still having access to a Computer Algebra System

CwiC 19

Lynnette Schultz

CwiC 20

Lynnette Schultz

CwiC 21: Cryptology

David Dimsey

A quick look at the mathematics of cryptography, and the use of programmed environments to develop cryptographic tools.

CwiC 22: Bertrand's Paradox

David Dimsey

This challenging paradox arises from a seemingly innocuous problem: "For given circle, what is the probability that a chord, drawn at random on the circle, is longer than the side of an inscribed equilateral triangle." Several contradictory solutions throw doubt on the whole notion of probability.

CwiC 23: Chaos on a spreadsheet

David Dimsey

The new mathematics of chaos has opened up many exciting fields of exploration for mathematicians and scientists. This session looks at setting up spreadsheets to provide visual, interactive models of chaotic situations.

CwiC 24: Exploring simple fractals

David Dimsey

Simple computer programs make investigations of fractals accessible to all mathematics students. These wonderful geometric objects provide rich opportunities for exploration, investigation, and hypothesising.

CwiC 25: Weblogs as a Tool for Classroom Flexibility Description

Rod Manson

Weblogs may be used as a personal or teaching website or as a reflective tool for use in multi task classrooms. They can provide enormous flexibility in a very simple and diverse way utilising easily accessible weblog software and web hosting.

CwiC 26: Crocodile Clips - Physics as a Tool to Improve Student Understanding of Difficult Physics Concepts.

Rod Manson

Crocodile Clips is a suite of software packages (Physics, Chemistry, Mathematics and Technology)  that are excellent at enhancing student understanding of difficult concepts. Crocodile Clips-Physics in particular has been used at Wesley College as a means of improving student understanding in the electricity topic. If time is available, then the other Crocodile Clips packages may be demonstrated.

CwiC 27: Inspiration as an organising and thinking tool across subjects

David Nettelbeck

This session is for beginners who don’t know the program and will download a 30 day free trial off the internet at the CWIC.

CwiC 28: Computers for whole brain learning and whole brain assessment

David Nettelbeck

This session is a ‘show and tell’ of some of the open ended units I have developed to branch away from the traditional and often narrow tasks we devise for students.

CwiC 29: Blogs

Karen Ward

As educators we know that feedback and formative assessment are two crucial elements leading to student success, but how do we realistically manage time and resources so we can monitor student progress while helping them monitor their individual growth?  Blogs will help you and your students converse individually towards this end.

CwiC 30: Visual Maps + Connections

Karen Ward

When students create hypermedia visual maps they make connections, become aware of their thinking patterns, and provide evidence of their understandings.  This CwiC will concentrate on the types of hypermedia visual maps both educators and students can employ

CwiC 31: Mathematical Modeling and Exploration with Learning Technologies

Josie Hopkins

Using SchoolKit as the vehicle, this session will demonstrate how you can provide your students with opportunities to DO Mathematics and THINK Mathematically.
