Distractors
> Word Permutations
- Zigzag
Generator allows you to assign distractors to textual segments
in a fully or partially automatized manner. In the first case,
the generation of distractors is done for all the textual segments,
without the user's intervention. However, partially automatized
generation of distractors allows for the choice of the best-suited
distractors among those suggested by Zigzag Generator,
for each segment of the text in turn. In order to fully automatize
the generation, the box marked Random Generation of Distractors
(Full text or Selected segments) must be checked.
- Selecting
the horizontal view (View > Horizontal View menu or
the
 button
of the toolbar) generally makes it easier to follow the process
of distractor generation. The following explanations will pertain
to the horizontal view. However, the vertical view facilitates
working in multi-selection mode (cf. Note
1 ).
Partially
Automatized Generation of Permutations
- Select
the menu Distractors > Word Permutations. A window
called Word permutations of a segment will appear:
- To add
a distractor to the text segments (also called target-segments),
click once on the checkmark labelled Generate Distractor.
The
selected distractor will be transferred to the test matrix (visible
in horizontal view only) as a result.
- This operation
can be repeated as many times as there are rows available for
distractors (with a maximum of five distractors for a matrix
with six rows).
- Once you
have created the desired number of distractors, click on the
arrow Next without Distractor to access the next textual
segment that is still without a distractor.
- You can
browse through the segments of a text in two ways:
- Click
on the arrow Previous without Distractor and Next
without Distractor in the
window called Word permutations of a segment.
- In
the integrated editor of Zigzag Generator (vertical
or horizontal view), select the textual segment desired.
It will then appear in the window called Word permutations
of a segment.
Fully
Automatized Generation of Permutations
- Instead
of selecting the distractors one after the other, you can randomly
generate them either for the whole text, or for the pre-selected
segments in the editor. In order to do this, check the box marked
Random Generation of Distractors (Full text or Selected segments).
- Determine
the maximum number of textual segments by using the arrows or
by inserting the desired value. (cf. Note
2).
- Click on
the checkmark Generate Distractors and then on Close.
Assigning
a Code to Permutations
- Using a
code allows you to obtain specific information on the segments
corresponding to that code. It is thus possible to code or not
code the textual segments affected by the command Distractors
> Word Permutations. The chosen code is visible in horizontal
and vertical view. Three options are available:
- Select
the button Use the code 'Perm'.
- Select
the button Use one of the following codes (cf. scroll-down
menu). This option is only available if other codes have already
been generated for the text. If it seems appropriate, one of
those codes can be reused.
- Select
the button No code. This option is to be used if you
do not require specific information for these segments in the
results section.
Note
1. In the vertical view, you can simultaneously select
many textual segments in the integrated editor of Zigzag
Generator (multi-selection mode). To do so, hold down the
Ctrl key while selecting the textual segments of interest.
These will change to red (and not dark blue as is the case for
singly-selected segments).
When you
are in multi-selection mode, random generation of segments is
applicable only to the selected segments (and not to the segments
of the full text). Similarly, in partially automatized generation
the arrows Previous without Distractor and Next without
Distractor allow you to access only the segments selected
at the time.
Note
2. The number of distractors per textual segment
cannot exceed the number of rows in the matrix, less one
row (i.e. the one of the target-segment). In fact, the number
of textual segments selected is often less than the maximal
number. This can be explained by the fully randomized selection
mechanism: when a textual segment is composed of many words,
the random algorithm chooses from among all the words having
at least one distractor (and not only from the words having
the maximum number of distractors).
