How to Improve this design, make people understand Accuracy?

March 28Hits:1

I have a rough design for a progress report, primarily to be shown on the iPad.

This is supposed to show what the kid is good at, and what the kid is not good at.

Feedback I've received:

  • It's not easy to make out that the number in the circles is Accuracy

Can someone suggest how to improve this and communicate what the values in the circle actually mean (or show it in an alternative way)?

Why not try visually showing their progress?

Also, the color of the bars can change as the progress changes, RED= 10-35% Orange=36-70% Green=70%-100%.

You're focusing heavily on the word "accuracy", but you're discussing the topic of skills. In an educational setting, the word "proficiency" better represents the goals of teaching, and teachers often measure proficiency by reporting the students' accuracy on tests. I would try to use the more appropriate word, as it will help reduce confusion.

Also, progress is an appropriate metaphor when teaching. An accuracy test is a single-point-in-time measurement, but progress is measurements over time. Even when you're reporting on the scores for a single test, it's part of the overall journey towards mastery.

As far as a confusing display, I agree. The colored circles are static and do not indicate anything. Your groupings aren't really ordered or complete.

Consider a display like this:

           Skills                     Proficiency

        1 digit              Needs improvement | Mastered
    multiplication          0%    25%    50%   |75%      100%
        Tables of 1   90%  [                   |       X   ]
        Tables of 2   80%  [                   |   X       ]
        Tables of 3   85%  [                   |     X     ]
        Tables of 4   92%  [                   |        X  ]
        Tables of 5    0%  [X                  |           ]
        Tables of 6   30%  [         X         |           ]
        Tables of 7   50%  [              X    |           ]
        Tables of 8    0%  [X                  |           ]
        Tables of 9    0%  [X                  |           ]

You could still use colors to highlight the skills that need improvement. But this solves some of your problems of ordering, grouping, while still indicating whether or not the students have achieved mastery.

Why not order skills by accuracy? Order shows the pattern.

How to Improve this design, make people understand Accuracy?

From what I can tell, there isn't much context to the percentages that are presented. What are they percentages of?

For example: "Skills to be improved - Subtract within 20: 30%". 30% what? If it's supposed to be Accuracy, it's not called out or made apparent anywhere. You could call it out or simplify the concept a bit.
