CS4HS – Writing Reports

Tim Bell, Canterbury University / Heidi

External reports that students have to write.
Upper limit is 14 pages – if writing that then too much!! Would be way above E. At all 3 levels.

Aim for around 10 pages for a report, may do it in 2 or 3 different ways.
Question is have they ticked off all the points?

Teachers Guide says what to do for each bullet point in the ASs. Plural – must have 2 or more. If only do one haven’t meant the requirements of the standard.
1.44 Demonstrate understanding of basic concepts from computer science

  • Don’t get students to write a programme, it is about comparing, download programmes – Scratch / Python
  • graph, linear scale, labels, titles e.g.”time taken for sorting”, key,
    • pick two algorithms that are quite different
    • good way to present, quite a bit of work to get out of Excel, label by curve
    • students need to articulate information about it, marker wants to know what the student knows about the graph
    • 1.44 – Python 2.7 – sorting algorithm / programme NZACDITT
  • other examples
    • no units, time taken – secs, mins,
    • quick sort, selection, bubble, insertion, merge, quick
    • Heidi has whole paper on it
    • practical example, okay for group to have an experience, but not okay for group to write the report, has to be individual
  • Teacher prompts – be very careful, open questions
  • personal experience / student voice
  • look at someone else’s user interface, show the interface
  • personalisation, sort of n! possible examples
  • evaluate an interface that you own – e.g. my phone, my alarm clock
  • How to lie with statistics – scale – 11, 21, 30, 38, 45, 51, 56, 60, 63, 65, 66
  • want genuine student learning to be happening – feedback from teacher on external reports

Embedded image permalink Get students to ‘tell their story’, be able to justify, it is important to justify, justify why something is stupid, not just say it is stupid.

Look at other things that are evaluated e.g. movie reviews and how they can be different, because people have different opinions.

  • For external reports, can add video, loose a couple of videos. Electronic, Google Docs – must be pdf.
  • Content showing the students understanding is the thing, not the formatting. If students get stuck on words help students with words so they can get content down.
  • Problem – something that needs to be solved, not a ‘bad’ thing. E.g. a sorting problem. Problems and their algorithm – problem is that I need to sort these numbers, solution is a sorting algorithm. There are lots of solutions to a problem.

Use scaffolding but are broad one, make it so it allows for personlisation.
