The Middle School Math Slide

Four explanations are live and they have different fixes: curriculum-pacing mismatch, implementation quality, staffing instability, and assessment-standards misalignment.

Test them cheaply, in about three weeks:

• Item-level analysis, not scale scores. If the drop concentrates in two or three domains the new materials de-emphasized, that points to pacing and alignment. If it is spread evenly across domains, suspect instruction or staffing.
• Disaggregate the disability gap. Pull rosters and ask whether the widening gap tracks the substitute's sections or a change in co-teaching. A 31-point gap is a service-delivery question, not only a curriculum question.
• Compare the four teachers. 78% whole-group instruction while six weeks behind is the diagnostic finding. If you are behind and still lecturing, the pacing guide is not what is costing you. Check whether the small-group rotation was attempted and abandoned, and by whom.
• One 45-minute teacher focus group asking a single question: where did you stop, and why?

What I would not do is buy the intervention program first. A $96,000 platform layered on 78% whole-group instruction with six-week pacing drift becomes a second unmet promise in 12 months, and the board will remember which one you chose.

Split both the money and the problem.

Instructional core (about $70,000):

• Fund a 0.5 FTE math coach, or reassign a strong teacher-leader with four-day coaching release. Coaching is the only lever that touches 78% whole-group instruction. Condition of the role: the coach models the small-group rotation in classrooms, not in a PD room.
• Pay for substitute release - roughly eight days per teacher - for observation and co-planning. Cheap, and it signals priority better than a memo.
• Have the team rewrite pacing around six power standards per quarter and put in writing that the rest may be skipped. Six weeks behind means the guide is unusable; teachers need written permission to cut.
• Stabilize the substitute's section: same unit pacing, a mentor, weekly check-in.

Intervention (about $40,000):

• Target only students two or more years below grade level with a small-group tutoring model delivered in-school during an intervention block. If a platform is chosen anyway, pilot with 60 students for one semester with a pre/post measure before scaling.

Defer the $96,000 purchase, and say why to the vendor and the board. Report item-level results in January.

Slow this down. 'Resistant' describes behavior, not a finding, and it is not a basis for a personnel decision.

• Ask for the evidence first. What did she observe, on what dates, with what feedback, and what was the teacher's response? If the answer is attitude in meetings, you do not have a case; moving them out will be reversed at hearing and will cost you the trust of the faculty you are asking to change practice.
• Separate three groups. Teachers who can't do it yet need coaching and time. Teachers who won't need a documented support plan with benchmarks and consequences. And some of the teachers may be right - when 78% of lessons across seven teachers are whole-group, the curriculum or the pacing guide is a co-defendant, not two individuals.
• Direct a six-week support cycle for each teacher: one specific target (small-group rotation three times per week), two observations with written feedback, one model lesson. Decide in May on evidence.
• If a teacher does not improve, use the contract's process. Do not use a transfer. A transfer relocates the problem and tells your best teachers that the district manages underperformance by moving it.
• Document, and loop in HR early so the timeline matches the collective bargaining agreement and state notice requirements. Hallway conversations about non-renewal become the teacher's case, not yours.
