Teacher Reporting

Description

A custom Moodle quiz module which, in addition to the standard Moodle quiz features, analyzes the questions posed to the student for various qualities, such as compliance with Curriculum Standards.

Group Members

• Project Manager: Wesley Dillingham
• Additional Group Members: Jeremiah Green

Goals

• Expand upon the PHP of the Moodle Quiz Module to parse questions involving mathematical operations for characteristics contained in the Massachusetts Curriculum Framework for Mathematics.

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

Milestones

Week 8

• Create Moodle data flow diagram to give an understanding of how the Moodle Server and corresponding database interact with Student and Teachers machines.
• Have Moodle's latest stable release functioning in an XS School Server VirtualBox OSE Virtual Machine

Week 9

• Have Moodle's latest stable release functioning on an XO running XS using the techniques outlined [here. http://wiki.laptop.org/go/XS-on-XO]
• Have mock PHP calls functioning.
• Parse mathematical-operation-based questions for student's understanding of order-of-operations and tally percentage of success with each individual operation (+,-,/,* etc).

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
