Of course they're not improving. The US education sector is like the US health sector - a device for increasing shareholder value among parasitic corporates, not for providing an effective public service. As a result it provides vanishingly poor outcomes which keep the US below the OECD average, in spite of some of the highest per-student spending in the world. Education is highly politicised, managed by school boards which seem to attract religious kooks and other low-quality authoritarians with eccentric ideas, and which does almost everything it can to discourage good teachers and other suspiciously well-educated and competent individuals from joining or staying in the profession. Widespread poverty in the US population doesn't help. Changing how math is taught won't address the essential dysfunctional broken futility of the system as a whole.
