2002: "Linear Functions 1"
This maths text book is one module of the Students' Integrated Maths Module project by OTRNet Publications. See http://www.otrnet.com.au for further information.
2002: The HP HOME View (http://www.hphomeview.com)
Starting in 1996, I created an extensive web site devoted to the needs of teachers and students who use Hewlett Packard graphical calculators. The site includes extensive help pages, a FAQ page, all relevant utilities, aplets and programs for teaching maths and science as well as games. In 1996, when the HP38G was released, Hewlett Packard released a collection of 50 aplets as support for teachers but did not offer any more after that. My web site currently contains more than 100 more teaching aplets and programs. Currently nearly all of the material, other than games, written outside Hewlett Packard was created by me.
2000: "Investigating Mathematics Through Patterns" (Books 1 and 2)
Under contract to Hewlett Packard, I wrote two books of teacher support material which were distributed extensively as free promotional material in Australia, the United States, South-East Asia, and India.
1998: "Some Observations Regarding the Use of
Graphical Calculators in the USA and Australia"
A copy of this article can be found at my web site in the Help section.
1988: "Mathematics in a Hospital"
This textbook was published by Hawker-Brownlow. Typesetting was done using Pagemaker.
1998: "Tips and Tricks"
I contributed a number of small articles on the use of the HP38G to the "Tips" section of the HPC magazine published by Hewlett Packard.
1996: "Mastering the HP38G Graphical Calculator - A Guide for Students and Teachers".
This alternative to the manual has sold extensively in Western Australia and a large number were purchased by Hewlett Packard in 1998 for distribution as free publicity material to schools world wide.
Miscellaneous Professional Activities
2007: Contracted by the Mathematics Association of W.A. to perform a two day professional development session for a small group of teachers from the north of Western Australia. The aim was to raise their ability with the HP graphical calculators up to a sufficient level that they would be able to perform their own professional development when they returned home.
2007: Contracted as the mathematics writer by the ASISTM Synchrotron Project, a federally funded project to produce cross-curriculum material linking the Mathematics and Science syllabi under the theme of the Melbourne Synchrotron.
2007: Contracted to provide a two hour introduction to CAS systems for the HP calculators at a HODs mass inservice conducted by CathEd and AISWA.
2005/6: Alpha tester and beta tester for the hp39gs and hp40gs released in early 2006. Proof-reader for the official HP manual.
2004: Requested to provide information on the HP Computer Algebra System to the calculator advisory board of the Curriculum Council for W.A.
2004: I presented a session "An Introduction to the HP CAS" at the State Mathematics Conference in Bunbury, Western Australia.
2004: I was requested to provide information on the HP CAS system to the calculator advisory board of the Curriculum Council for W.A.
2004: I was a beta tester for the new connectivity software for the hp 39g+.
2003: I was a beta tester for the new hp 39g+ graphical calculator.
2000: As part of an HP/Palm collaboration project code named Prometheus, I was asked to evaluate a new type of graphical calculator design. I was asked to assess its suitability for use with pre-calculus classes in mathematics.
1999: As part of a follow up visit to India I again travelled to India and presented to groups of teachers of mathematics in a variety of schools in New Delhi. As part of the visit I was also asked to discuss aspects of the take-up of such technology in the classroom setting, with appropriate demos to exemplify points, at a seminar with the staff of the NCERT (National Council for Educational research and Training). This is the national body with responsibility for developing the curriculum, and promoting the writing of texts to be used (from year 1 to 12), and also responsible for making recommended changes to teacher education. Their main concern was the implications of the new technology for teacher training and re-training.
1998: At the invitation of the Australian Association of Mathematics Teachers I travelled to India as part of a project partially sponsored by Hewlett Packard and organised by Jeff Baxter to stimulate the uptake of technology in Indian schools. I taught demonstration classes in a variety of schools in New Delhi and gave many talks to groups of teachers. I also addressed Principals at the regional Principal's Conference in New Delhi, giving a demonstration of the capabilities of the calculator and its use in teaching mathematics. At the end of the conference the mood was extremely positive and the most common questions on the feedback forms handed out were "How soon can we buy these?" and "Why are they not available now?".
1996: I was requested by the Mathematics Syllabus Coordinator of the Curriculum Council, as part of a group of calculator experts who were also practicing teachers, to analyse the past five years of Tertiary Entrance Examination papers in the light of the proposed introduction of graphical calculators. We reported on what proportion of problems would have needed no revision, minimal revision or would have needed to be discarded if students sitting the examination had had the use of a graphical calculator of whatever brand.
1989: I was a member of the Western Australian Syllabus Sub-Committee which designed the new upper school mathematics courses for Western Australia of "Maths in Practice" and "Modelling with Mathematics".
Highly proficient in: C, HPBasic, Pascal, Filemaker Pro Scripting language
Moderately proficient in: C++, sRPL, Visual Basic, Fortran, SQL, TI & Casio Basic
Major computer packages used regularly
Computer Applications and Graphical Calculator Software
2006: Principal beta tester for new Aplet Development software for the hp 39gs and hp 40gs models.
2005: Principal beta tester for the hp 39gs and hp 40gs model graphical calculators.

2003: I developed an extensive archive of exam papers for use by Year 11 and 12 students studying for their mid-year and end of year examinations. This archive is in the form of a web-site contained on a CD, distributed free of charge to students. In addition to exam papers the CD also contains a great deal of support material for students in the form of programs for the PC and for the HP39G, help files, tips and tricks, web links and other documentation. This archive now forms part of the school intranet instead of being CD based.
2002: During 1996 I was first introduced to the Hewlett Packard HP38G graphical calculator. I began to produce aplets (small applications) and programs for the calculator for use in my own classroom. This drew attention from Hewlett Packard and resulted in sponsorship to various conferences to present on topics relevant to teaching with Hewlett Packard graphical calculators. I subsequently developed a wide range of aplets which are available free of charge via my web site The HP HOME view at http://www.hphomeview.com This development continues to the present day.
Some of the applications which I have developed have been incorporated into subsequent models of the calculator. For example, the "Quadratic Explorer" and "Trig Explorer" developed as downloadable aplets for the HP38G were incorporated into the BIOS of the HP39G and HP40G. Similarly, the "3x3 Solver" has been included in the BIOS of the hp 40g+.
2002: I created very extensive Powerpoint displays with animations of button presses and resulting screens for the new HP9S scientific calculator and the new HP9G low-end graphical calculator. These were designed to be used by Hewlett Packard as promotional material for distributors.
2002: Electronic User Manual for the HP39G
I used Adobe Acrobat Editor to index and hyperlink the electronic version of the manual for the HP39G and posted it on my web site.
2001: At the request of my school I evaluated the capabilities of the Texas Instruments TI83+ and the Casio CFX9850GB Plus and FX-2 as possible alternatives to the HP39G. My evaluation included the abilities of the calculator in handling the type of mathematics covered in the upper school courses in Western Australia, the resources available to users via the web for each calculator including software, and the power and usability of the programming language provided with each calculator. As part of this process I became proficient to a moderate degree with each of these calculators. I also translated a some of the teaching programs that I had written for the HP39G into each calculator's language noting any difficulties encountered.
2001: Working with a group of programmers, I assisted in the adaptation of an existing PC emulator of the HP48 so that it would also emulate the HP38G and HP39G on a PC. This included a large screen version which could be used by a visually impaired student. This process involved porting many of my aplets to the emulator.
2000: I created a web based "virtual sponsor's desk" for Hewlett Packard at the Virtual Conference 2000, a conference held on the internet and administered by AAMT.
2000: As part of a contract with Hewlett Packard I participated as a team member in the Enterprise project to create the HP39G & HP40G (with CAS). These two new calculators are the successors to the HP38G.
My tasks in this project were to write the Functionality Specifications for the new calculator, to co-ordinate the Keyboard Design Group, to contribute to the User Manual, and to beta test the new calculators. I was also required to evaluate the porting of the Computer Algebra System from the HP49 to the new HP39G. This evaluation included testing, advising on the user interface and proof reading of the manual.
2000: I created a Powerpoint display with animations of button presses and resulting screens for the new HP30S scientific calculator.
2000: I adapted and updated an existing Powerpoint teaching/demonstration display to work with the new HP10B2 business calculator.
1999: In collaboration with a Swiss programmer, I aided in the creation of a new and updated version of the communication software allowing download from a PC to an HP38G or HP39G. I contributed to the user interface, testing at the alpha and beta stages, and I produced the extensive help file.
1998: At the request of Hewlett Packard I designed two aplets for the HP38G for release at the calculator's official launch at NCTM in the USA. I created the user interface and functionality specifications, while the machine code level programming was done by two Hewlett Packard programmers. The result was "Quadratic Explorer" and "Trig Explorer". By 2000 these were considered so crucial to the calculator's success that they were incorporated into the BIOS of the next generation calculator, the HP39G.
1997: At the request of Hewlett Packard, I produced a series of five aplets for the HP38G all of which used the Firmware datalogger with various probes to perform science experiments. These were passed on to the Science Teachers Association for evaluation and later distribution.
1995: I designed, programmed and implemented a reporting system for the school using the scripting language of the Filemaker Pro database. This system continued to be used at my school until 2001 and I was the principal administrator of the system. As part of this task I designed and presented training courses for staff at the school on how to use the package. Many staff were not computer literate and so this involved considerable training in many cases.
1991: As part of my Grad. Dip. Computing, I wrote a package called "Statpack" in the programming language C for use in schools. This package allowed editing and graphing of univariate, bivariate and time series data, giving all relevant descriptive statistics, as well as the simulation of observations on most common random variables. The aim of the project was to make the package as user friendly as possible. Subsequent sales were made to a number of schools in Western Australia but the use of the program phased out as Windows computers became more common.
2007: Presented at the MAWA State Conference on the HP CAS system.
