block_progress.php

<?php
/**
 * This class is designed to show a student what progress they have made with their
 * 'courses'. It is designed to support the use of criteria-based assessment,
 * specifically the Pass/Merit/Distinction criteria used by exam boards such as
 * Edexcel in the UK.
 * Works in Moodle 1.9+
 *
 * there are certain steps required to get students' progress to display correctly.
 * please see the pdf walkthrough included in this folder (walkthrough.pdf)
 * briefly:
 *     	enable outcomes (done by the admin)
 *		set up a new site-wide scale '-,Y' called EDEXCEL (or a name of your choice)
 *		IN EACH COURSE
 *		add an outcome for each criteria, the first letter of the short name is 
 *		important (all pass criteria must start with a capital P, merit M, 
 *		distinction D).
 *
 * original author Mark J Tyers mark@zannet.co.uk * @version 23/07/08
 
 * UPDATE 03/07/08
 * if a grade has been achieved and progress is being made towards a higher grade
 * the full bar is faded out and a new bar overlayed to show the progress
 * towards this new higher grade.
 * bars now show true fraction (removed the initial increment from bar).
 *
 * TO DO
 *      allow the use of other citeria scales (set on the configuration page)
 *      implement a footer (or a choice of different footers)
