Parsons Problems

Codio introduces a new type of assessment: Parsons Problems

What are Parsons Problems?

Parsons Problems are great formative assessments that ask students to arrange blocks of scrambled code - allowing them to focus on the purpose and flow of the code (often including a new pattern or feature) while not worrying about syntax.

When students think they have completed the task correctly, Parsons problems offer feedback - highlighting any problematic lines. Students can then try to fix their code and re-submit:

Why Parsons Problems?

While Codio offers auto-grading for more open-ended coding exercises, writing code is a time-consuming task for students. So in addition to asking students to predict the output of existing code, Parsons problems offer another way to expose students to code without requiring large amounts of time. In fact, research shows that while Parsons problems take “significantly less time  than fixing code with errors or than writing the equivalent code... there was no statistically significant difference in the learning performance, or in student retention of the knowledge one week later.” [1]

Additionally, as students make their way through units and semesters, the amount of work they do decreases. However, Parsons problems have been shown to be one of the most engaged with features on interactive platforms despite the drop off in student completion of tasks. [2]

Creating Parsons Puzzles on Codio

Parsons Problems are available now on Codio as Parsons Puzzles and creating them is easy:

  1. Go to the drop down for assessments like you would for any other assessment type and select Parsons Puzzle
  2. Name the puzzle and paste in the correct code
  3. Add distractor blocks (if you want) and click save

To learn more about how to add Parsons puzzles to your courses on Codio, see our full documentation:  Parsons puzzles
