This sounds very much like the discussion of whole-language vs phonetics approach to teaching children to read, which forms part of the instructor training. The summary for that example is that it doesn't matter - you just need to be enthusiastic.

I’ve done both with teaching R. I don’t have any data, but I far prefer the top-down approach. My version of top-down is to give them code that works to make a standard plot. That lets them make something tangible in the first 5 minutes. I then have them look at the code and ask how they would change colors, plotting symbols, etc. Then I ask them how they would make a new plot using a different column from the data file. I then wash, rinse, repeat building in new programming concepts to do different analyses and methods of visualizing data. I far prefer this approach over building up from “Hello World” because they get going immediately and because that’s how many of us learned to program. At least for me, I learned by taking code that someone else generated to do a task and hacked at it to suit my needs. Whenever I find a new package, I take their vignette and hack at it to learn how the functions work. It seems like most programming books are bottom-up while more domain- specific materials are top-down. I agree that it would be very interesting to hear other opinions and whether there are any data supporting one strategy or another… Pat On Nov 11, 2016, at 3:07 PM, Peter Teuben <[email protected]><mailto:[email protected]> wrote: forgive me if this is something covered before but I'd like to contrast two opposite ways of teaching a language What i mean is to teach something like python, you can go through the rigorous language elements (which can be pretty boring) and build up your skills to the level that you can program. This I would call a bottom up style. The other approach is you pick a problem in the field of your students (in my case astronomy, so my example may not work for biology students), and disect it and teach them the language elements as you go. I would call this top down. Has this approach been tried and has it been found at least equally good? Of course the huge drawback is that it only applies to a small group of students. I'm curious to try this. - peter _______________________________________________ Discuss mailing list [email protected]<mailto:[email protected]> http://lists.software-carpentry.org/listinfo/discuss _______________________________________________ Discuss mailing list [email protected]<mailto:[email protected]> http://lists.software-carpentry.org/listinfo/discuss ________________________________ Founded in 1821, Heriot-Watt is a leader in ideas and solutions.
