Some potential changes and resulting opinions include:
* Focus on mastery: Systems emphasizing mastery learning (requiring students to demonstrate proficiency before moving on) might be favored by some students who appreciate clear expectations, but disliked by others who struggle to meet the high bar. Teachers might appreciate the focus on understanding, but find the workload of providing differentiated instruction and assessing mastery challenging.
* Standards-based grading: This approach often grades skills individually, rather than averaging everything together. Students might appreciate seeing their progress in individual areas, while others find it overwhelming to track multiple grades. Teachers may find it more accurate than traditional grading but more time-consuming.
* Weighting of assignments: Changes to how much different assignments (e.g., tests vs. homework) count towards a final grade can cause both positive and negative reactions depending on a student's strengths and weaknesses, and a teacher's teaching style and workload.
* Pass/Fail grading: While simplifying things for students and teachers, this often lacks the detailed feedback necessary for improvement and might be viewed negatively by those seeking a precise measure of achievement.
In short, to answer your question, more information is needed about the specific grading system being discussed. The response is highly contextual.
