Understanding Kaligo letter analysis and scores

Kaligo’s handwriting feedback focuses on letter shape, order and direction. Although the feedback may occasionally appear incorrect, we assure you that it is essential for achieving precise writing.

Here is how our feedback system operates:

"I write a correct F, but I receive an orange result."

"I write an incorrect E, but I still receive a green result."

There may be several explanations for this situation:

1. The student might have made a mistake in forming the letter such as the stroke’s order or direction.
2. The letter might be partly correct or incorrect, leaving it open to personal interpretation.
3. The student's difficulty level is either too low or too high.
4. There is a mistake to be corrected in this letter.

1- How Kaligo decides what score to give to a written letter

Kaligo uses several criteria to give a score to a written letter (or a group of letters).

• Shape of the letter
• Order of the stroke
• Direction in which the student has written
• Position of the letter in the line
• Pencil lift

If any of these criteria fail to meet the standards set by the teacher in the supported models, the overall tracing score will be downgraded.

Example: The student has traced a very good “H”, so why is the score is so low:

By clicking on the "?" icon next to the score, you can compare an animation of the expected letter formation with the child's drawing. This helps identify incorrect direction.

(From the "Letter choices" tab in the teacher's portal, you can specify supported H letter templates and the stroke order and direction.)

Kaligo also alerts you if lines are crossed or the pencil is lifted incorrectly, though this doesn't affect the letter's final score.

2- Neither good nor bad letters

When a letter is written well or badly, everyone agrees. But what about letters that are almost right?

If the strokes are in the correct direction and order, then it's the letter's shape that needs to be analysed. Unlike direction or order, judging the shape isn't just about saying 'good' or 'bad', but about 'how closely it matches the model', which is much more subjective.

Take the example below:

The first R is undeniably well-formed. However, the same cannot necessarily be said for the following ones. For instance, does the third R deserve a good score? Should we encourage the 5-year-old who has written it? Or should we penalise the 8-year-old who didn’t do it well enough? So what score should Kaligo give these letters?

In your teacher portal, you can choose the difficulty level (and therefore the feedback tolerance) per student or class.

3- Adapting the difficulty level to the child

In addition to the specific colour and size parameters, you can also choose a difficulty level for your class or for each child.

If you find that your child's scores are too low, consider reducing the difficulty level to promote progress.

To do this, go to the “Classes and students” tab, then select a student. Then click on the “Settings” tab at the top of the screen, and go to the Feedback section.

4- One or more letters keep causing problems

Despite our careful measures, issues may arise, and our technical team may need to address them. As we improve our analysis, some letters may experience setbacks. While we're vigilant, occasional bugs may slip by…

So don't hesitate to send us screenshots, or even better, videos showing the direction of the lines and the difficulties you’re having with a letter. This will help us fix issues as quickly as possible.
