Blackboard Analysis Tool

Github page, blackboard.com

An analysis automation tool to avoid repetitive task while grading student assignments that have been handed in through the Blackboard learning system.

For example: * Extract hundreds of .zip files * Sort the files per assignment, student * Create statistics: number of students, late assignments,…

Installation:

  • Download the source and run python setup.py install.
  • Python Package available in the Python Package Index at: http://pypi.python.org/pypi/blackboard_analysis_tools/.
  • Install using pip: pip install blackboard_analysis_tools.

Usage:

  • Download assignment files from Blackboard (e.g. gradebook_ART_EA-38302_Assignment1_2013-06-11-20-50-44.zip).
  • Place these .zip files in the “input” folder.
  • Run the program: python -m blackboard_analysis_tools.
  • Wait… (about 10 seconds when processing around 100MB of assignments) (time will vary).
  • Open the “output” folder to see the results (all files sorted per student, a summary, logfile, …).

What is happening behind the scenes:

  1. Scan for .zip files
  2. Extract the .zip files
  3. Scan for .txt files (these contain the metadata that describes the student reports/assignments)
  4. Analyse the .txt files
  5. Create a folder for each student
  6. Move all the files to the correct folder (including those with filenames that have been ‘mangled’ by Blackboard)
  7. Write some statistics: a list of all students that have handed something in
  8. Write a summary of the process: number of students, number of assignments, number of ‘mangled’ files,…
