Parsons Problem Webapp

Parsons programming puzzles are a type of scaffolded program construction tasks where the learner is given a set of code fragments, blocks of a single or multiple lines of code, and the task is to piece together a program from these. Learners not only select and order but also indent code fragments.

They are challenging problems that reduces the cognitive load and time spent for students.

This variant of Parsons programming puzzles is called two-dimensional (2D) Parsons problems. In Python, code indentation has a semantic meaning, as an indented statement falls into the surrounding control structure, which has lower indentation. That is, code blocks are defined by indentation instead of start and end symbols like curly braces.

(from js-parsons)

The use of Parsons puzzles is an evidence-based teaching practice.

Based on js-parsons and inspired by Python Tutor.

TODO

  • [ ] Use the better version of Runstone.
  • [ ] Various view: stand-alone, embedded, LTI
  • [ ] Problem library
  • [ ] Add tests
