Setting a grade percent minimum
In my middle school all students are required to maintain a 90% or higher on all lessons. How do I set this minimum to pass a lesson on Duolingo?
This is my feeling: We are working toward mastery, right? Duolingo lessons themselves work toward mastery. You get a question wrong, then that question keeps getting repeated until the student gets it right.
Therefore, every student who completes the Duolingo assignment gets 100%.
Now, if they AREN'T doing their assignments, then obviously that's a zero for each assignment that they miss. Or partial credit if they got 25 XP when you assigned 50 XP, or they did a couple of lessons on the "restaurant" skill but did not level up.
That's just my two cents, and how I grade my own students.
