Goals

  • Run Moodle with the modified quiz module on an XO running XS, The XO school Server.

Week by week milestones

  • Week 8: Have both scripts succesfully tabulating relevant information
  • Week 9 :Have student to teacher data information transfer succesfully functioning with scripts.
  • Week 10: Have integration with kuku, and a gui for teachers data retrieval.

"Required Accomplishment"

Wes

  • Get StudentParser.awk to successfully calculate the accuracy for each mathematical operation, plus other relevant information TBD, one example will be success of division with remainders.
  • Get ClassParser.awk to successfully calculate class-wide statistics on the same information
  • Provide Grader.awk which grades each student, calculates a class average, tallys students in each grade interval.

Jeremiah

  • Create Moodle data flow diagram to give an understanding of how the Moodle Server and corresponding database interact with Student and Teachers machines.
  • Install Moodle server and DBMS on a test Virtual Machine.
    • Attempt PHP calls to the Moodle DBMS.
    • Attempt to create a simple Moodle module extension which can be further built off of to provide further functionality.
  • Provide a script to move StudentParser.awk's output to ClassParser.awk's input

StudentParser.awk Input file format:

Field Structure:
"Mathematical Operation" "Correct?"

example:
45/67 y

StudentParser.awk Output file format *Incomplete*

Field Structure:
line 1: "Student MAC-Address"
line 2+: "Operation type" "correct in decimal"

example:
0:1e:8c:25:a0:c1
+ .86
- .84
x .91
/ .86

Grader.awk:

#!/usr/bin/awk

# grades -- average student grades and determine
# letter grade as well as class averages
