Evaluating learning can be simple if there is structure, feedback and agreement of process.
Using letter grades is the most effective way to start a conversation with the learner. The standard grading is:
90% or above = A
80% or above = B
70% or above = C
60% or above = D
59% or below = F
This is the beginning of the learning for the learner, not the end.
Use letter grades to give clear feedback on learner performance
Break out what feedback you are giving to the learner to improve to the NEXT grade level.
A grade = Give broad feedback on what they got wrong and get them to come to you if they have issues
B grade = Show them their incorrect answers and ask them to resubmit how they would change their answer
C grade = Give them their incorrect answers with 2/3 hints on how to complete them. They can get a friend to help them
D grade = Give them their incorrect answers with two written out the correct way. Get them to justify how that answer is correct
F grade = Give them the answer key and get them to highlight a difficult question they got wrong for more feedback
Help the learner find out what they can do to improve
Improving the evaluation
Share your process of marking with other educators and your manager and get agreement on best practices and how much time you are to allocate to marking. If left unchecked the time and energy for marking can detract from being effective in lessons.
Evaluation can be in the form of a written test, oral evaluation, negotiation and dialogue with the student to check learning, and even the students own self-evaluation.
