Note: You are currently viewing documentation for Moodle 1.9. Up-to-date documentation for the latest stable version is available here: Programmed responses question type.


The programmed response question type for Moodle 1.9 gets the question answer through a set of editable and non-native PHP functions. Useful for maths or statistics exercices which requires complex operations to get the answer.

Features

  • Users can add variables to the question text, the variables takes random values depending on

the user selection: max value, min value, increment and the number of values (scalar/vectorial - float/array)

  • The function arguments can be one of the question text defined variables, a concatenation of defined variables or fixed values.
  • User interface to allow the addition of functions. These functions can return one or more values, useful for example to return confidence intervals.

Requirements

  • Moodle 1.9.x
  • Users with Javascript/AJAX support enabled

Usage

  1. 1st step (optional): Variables can be added to the question text following the next format: {$varname}

The variables only accepts alphanumeric characters.

  1. 2nd step (optional, depends on the first step): Each variable must define the maximum and minimum values it can take, the increment and the number of values, to allow vectorial variables.
  1. 3rd step (optional): Add concat variables, useful if there should be a vectorial variable which values follows different criteria
  1. 4th step: Select the function which will calculate the answer (read ADDING FUNCTIONS to know how to add functions)
  1. 5th step: Assign each of the function arguments to a variable or a concat variable, the function can also use a fixed value as argument

Adding functions

There is an interface to allow the addition of functions; preceding the php implementation of each function there should be a comment block following phpdoc format, to specify the arguments description and the returned values.
