Supported commands

Command name Params Description

show --- Shows the module if it is hidden.

Show Answers

This module is fully compatible with the Show Answers module and displays correct answers when an adequate event is sent.

Scoring

The Writing Calculations module allows the creation of exercises as well as activities.

Property Description
maxScore Number of defined input fields.
score It's 1 point for each properly filled input field.
errorCount It's 1 error point for each input field filled incorrectly.

Events

The Writing Calculations module sends the ValueChanged type events to the Event Bus when a user fills in either one of the fields.

Field name Description
Item Field identifier in <row_number>-<gap_number> format, i.e. 1-2 means input with row = 1 and gap = 2 (each gap is counted in a particular row, not from the beginning of the equation). Both row and gap numbers are counted from 1 to n.
Value Filled value.
Score It's 1 if the filled value was correct, otherwise 0.

When the user fills in all fields properly, the module sends the 'ALL OK' event. This event is different, so its structure is shown below.

Field name Description
Item all
Value N/A
Score N/A

.wrapper-cell Wrapper for a single cell.
.container-emptyBox Container with single input representing input box (square brackets).
.container-helpBox Container with single input representing help box (curly brackets).
