Results Charts 2: Learning Bands

Following on from the blog showing how to produce the times tables charts, this blog utilises the same charts but now uses them to produce a chart showing learning bands. In an earlier blog we outlined the research Flurrish and Caddington Village School had completed to ascertain the hardest times table and what this then says about the order in which you learn times tables, something St Matthews (Luton) call learning bands. In that blog we presented our times table chart, but this time showing the order in which learning bands are produce..... click here to see it. So, how do you produce these?

Like the previous blog, this again uses the open source statistical package R and you can download the script itself, learning bands (for St Matthews) and the PDF chart.

This time the data spreadsheet has three columns and 145 rows - after the column titles, each of the 144 times table questions (noting the factor and multiplier) and the band it falls in are listed. As per the previous blog, there are three things you need to do:

A. Edit the following lines in the file:
1. Change the directory to the location of the file/data (currently set to C:flurrish)
10. Change the filename to the input data set you are using (currently set to the supplied filename). The data MUST be a CSV and MUST have the same column names
12. Change the range (number of learning bands) for the data set used: currently set at 0-9 bands. Due to the way the script calculates the legend, the range needs to be set to the number of bands + 1. In this example there are 8 bands, giving a range of 9.

B. Copy all of the text, start R, paste all the text in to the R console window (the very first time you might get a message asking to install the "colorRamps" package which you need to accept).

C. Open the "Learning_Bands_plot" PDF.

And that's all there is to it!
