Which barrier would interfere the most with achieving a goal of increased student achievement in math?

• A. The unexpected resignation of a math teacher
• B. A minor scheduling adjustment
• C. A new textbook
• D. A classroom with ample resources

Answer: (A)

Stability in teaching is essential for building math achievement. When a teacher unexpectedly resigns, the class loses not only a daily source of instruction but also the ongoing relationship, pacing, and instructional momentum that help students grasp sequential math concepts. A replacement needs time to prepare, learn the curriculum, and establish trust with students, which often leads to lost instructional time and misalignment with ongoing goals. That disruption can ripple through planning, assessments, and student motivation, making it the biggest barrier to raising achievement. By contrast, a minor scheduling adjustment is usually manageable with minimal long-term impact, since it can be rearranged without derailing the entire learning sequence. A new textbook is a resource that can support instruction and potentially improve outcomes if used well. A classroom with ample resources creates favorable conditions for learning and typically aids achievement rather than obstructs it.
