R & D

Over the last month I have been doing a few different experiments, with the Raspberry Pi and Mathematica, to develop a number of different lessons/experiments for our students. I don’t have much time  for educational theorists so I take an empirical approach to teaching and believe it is important for teachers to be counted among “those who can do”.

Theory often motivates many changes to the educational system in this country. Consider recent changes to the New Zealand Maths Curriculum, which introduce more emphasis on statistics. The changes seem sensible. Students now gain a better understanding of the statistical process and the variability inherent  in sampling and data.

Nevertheless, there are problems with the implementation of this new approach. The usual problems of NCEA , where teachers spoon-feed students and teach directly to the  assessment they deliver, are common. Technically speaking, it seems that students gain the understanding that  Statistics is a narrative activity (a form of story telling). I  am not in favor of the narrative  approach, since many flaws in statistical reasoning are caused by our tendency to tell stories and  join the dots. I encourage my students to withhold judgment, unless there is strong evidence, and to also consider base rates when making  inferences. Story telling seems particularly prevalent when it comes to time series analysis.

Maths and statistics students should develop a maker mentality and that means they need to code. Essentially, code is maths brought to life. While report writing and analysis has it’s place, it is  a bureaucratic activity, while  making  and experimentation leads to new ideas, technology and growth. The thoughts detailed in this video do match my experience when it comes to using maths.

My post,Wi Fi to the Beehive and Raspberry Pi,in the Wolfram Community shows how running a few experiments leads to some interesting new ideas.




Benchmarking Mathematica on the Pi

Mathematica on the Raspberry Pi is very usable for basic mathematical and programming tasks. This is the benchmark report.


Here is a comparison with my desktop which runs very well.



Mathematica on the Raspberry Pi

I have been using Mathematica for about three years. I have thought about getting my students to use it, and now seems the right time since it is freely available for home use on the Raspberry Pi.

I believe that programming skills are essential if students are going to bring maths to life and solve interesting problems. If you can’t convert mathematical concepts into code, advanced maths skills are of little practical use. The screenshot shows Mathematica code run on the Raspberry Pi.
