Workshop descriptions

The descriptions below may be updated but we don't expect major changes before the day.

1. Vectors and geometry (ME-V1)
Vectors provide a powerful and elegant to way to describe and solve geometric problems and are essential in physics and engineering.  Vectors will be introduced as both algebraic and geometric objects and used to prove results such as "the midpoints of the sides of a quadrilateral join to form a parallelogram".  The dot product will be discussed and used to find the projection of one vector onto another.

2. Vectors, lines and projectile motion (MEX-V1, ME-V1)
After a brief review of vectors through a game (please install the Kahoot app on your phone or bring your laptop), we will see how a straight line can be very naturally described using a point and a vector.  We will then see how projectile motion can be restated in the language of vectors, and we will explore the benefits of this approach.

3. Differential equations, direction fields and modelling (ME-C3)
A direction field is a tool for understanding the behaviour of the solutions to a differential equation even when explicit forms of those solutions are not known. The latest draft of the Extension 1 syllabus introduces direction fields along with an expanded range of differential equations used for mathematical modelling in chemistry, biology and economics. In this presentation direction fields will be explained and used to explore the behaviour of important mathematical models of real world phenomena.

4. Networks and paths (MS-N1, MS-N2)
The rise of online social networks has put networks in a bright spotlight, not only for the general public but also for researchers across a wide range of research fields, including biology, psychology, computer science, physics and beyond. This workshop will present a useful glimpse into the study of networks. After presenting the basic definitions and properties of networks, paths, cycles, and trees, we will discuss and practice algorithms for solving practical problems on networks, such as finding shortest paths (as in Google Maps, for instance) and minimal spanning trees.

5. Critical Path Analysis (MS-N3)
Critical path analysis is a tool for analysing a multistage process by modelling it as a network and finding the bottlenecks. This networks related topic from the new Stage 6 Mathematics Standard syllabus will be explained through the use of examples.

6. The max-flow/min-cut theorem (MS-N3)
The Max-flow/Min-cut Theorem relates the maximum through put of a network (eg water pipes, roads, the internet, etc) to the minimum cuts required to break the network. This networks related topic from the new Stage 6 Mathematics Standard syllabus will be explained through the use of examples.

7. Discrete random variables including the binomial (MA-S2, MA-S3, ME-S1)
In this session we will discuss random variables and the difference between continuous and discrete random variables. We concentrate on discrete random variables, giving examples including detailed discussion of the binomial distribution. We will discuss expected value and variance and the relationship between the mean of a sample and the expected value (the mean) of a random variable.

8. Continuous random variables (MA-S2, MA-S5, MS-S5)
In this session, we introduce the basics of continuous random variables through discrete random variables. We will generalise the concepts of the expected value (mean), variance and quantiles to continuous random variable. To illustrate the theory, we will study examples including the continuous uniform random variable, the normal random variable and the Galton machine (Normal approximation to Binomial random variables).

9. Thinking statistically (MS-S1, MS-S2, MS-S3, MS-S4, MS-S5; MA-S1, MA-S2, MA-S3, MA-S4, MA-S5; ME-A1, ME-S1)
Statistics and Statistical thinking are part of the new maths syllabus. This session is an introduction to what it means to be thinking statistically. We will introduce a variety of online and other resources for reviewing stats concepts and techniques, assisting with development of project based assessments and using technology. We will introduce the ( award winning) school poster competition run by the Stats Society of Australia and explain how to use this competition and the associated resources to support teaching.

10. Randomised assignments
Assessment in mathematics is very often in the form of a supervised test with a relatively short time limit. While this is easy to control, it is not an environment that encourages mathematical thinking and communication. Assignments are set to become a bigger feature of HSC Mathematics with the introduction of the new syllabuses. They offer the chance for students to take their time to craft good answers and explore more complex problems and can better assess skills in these areas. However, traditional assignment answers can be copied, reducing the integrity of this form of assessment. Computer generated randomised assignments can help to reduce the incidence of copying and restore confidence in their use. They can also be used to encourage student perseverance by offering options for students to verify their answers. Some examples of randomised assignments used in first year at UNSW and high schools will be presented and their advantages and limitations discussed.

11. The nature of proof (MEX-P1, MEX-P2)
This talk will look at the new topic to be introduced to the Extension 2 HSC course. As well as outlining the topic, we will look at many examples of the type mentioned in the syllabus as well as considering some harder examples of proof by induction.

Randomised assignments workshop using NUMBAS

A separate day devoted to a hands on workshop on setting randomised assignments using NUMBAS will be held on Thursday 28th June.  The workshop will run from 9am to 3pm.  Topic 10 in the PD Day described above is a showcase of some randomised assessments and discusses their advantages.  This day is a hands on workshop where you will learn to create your own randomised assignments and quizzes.

NUMBAS is a free open source web based system for creating and the automatic grading of randomised assessments.  These assessments can provide customised feedback and worked solutions. For on overview of NUMBAS see their website.

NUMBAS assessments run in a student's web browser, so no special software is required.  They an be either stand alone webpages or integrated with LMSs such as Moodle, Canvas, etc.  NUMBAS assessments and solutions can also be provided on paper.  Teachers can draw from a bank of publically available questions but, more importantly, can easily construct their own, which can be shared within private groups of contributed to the public bank. While simple questions can be easily constructed with little expert knowledge, the system also allows more advanced users almost limitless freedom.

The day will start with an overview of NUMBAS but most of the day will be spent working with the system to construct questions and assessments. Participants should bring along examples of assessments that they would like to convert to this format.  The questions and assessments produced on the day will be shared with the group and everyone should leave with a collection of assessments they can use in their teaching and the skills to create more.


NESA Completing the Randomised assignments workshop will contribute 5 hours of NESA Registered PD addressing 3.4.1, 5.1.2 and 5.2.2 from the Australian Professional Standards for Teachers towards maintaining Proficient Teacher Accreditation in NSW.
