Last things first: I asked my students to give me anonymous feedback about my grading system in comparison to the traditional system, ten of them did it and the results are quite interesting.
These are the results:
100% of them think its very fair
100% think it's easy to understand and to manage
30% think it's very important to have this system in other subjects
20% think it's somewhat important
40% think it would be nice to have
10% think it wouldn't be necessary but they wouldn't mind if this system would be used in other subjects
40% accessed the platform where they could track their XP more than 1 time a day
30% accessed the platform once a day
30% accessed the platform every couple days
70% find the XP based grading system very motivating
30% find it somewhat motivating
80% think the XP based grading system is clearer than traditional systems
90% say it's easier to study if they know exaclty how many XP they need to level up to the next better grade
90% say its very important to see their grades live on a website
And the (for me) most important question and the main reason why I did this whole XP based grading stuff:
I'm happy to say that all my students passed this year and I'm glad I can accompany them to their graduation next year.
I feel that the XP based grading system has helped some of the weaker students because they can really focus on a topic and they know what they have to do to pass. They can put the information I give them in a better context and always know where they stand.
XP BASED GRADING EXPERIMENT -> SUCCEEDED
So what's next?
I am currently working on an improved XP based grading platform (website) that makes it easier to use (for teachers) since many of my teacher colleagues said they would be interested in testing this system in their subject but find the website to hard to understand.
I am pretty sure I'll have the website finished by the start of the next school year (in September) and I hope I can motivate other teachers to use this sytem and help students to put everything they do into context.
Also I just got 48 Steam accounts from Valve as part of their teach with portals initiative. I am very excited to use Portal 2 with my students!
