WP series of the Math Stagnation Nation series, for New Zealand (over the past 15 -20 years and how to overcome this with MMU series)

In this short paper, the author concisely demonstrate the math stagnations of the national average of New Zealand over the past 12 years (for PISA math) and 20 years (for TIMSS math) and provide the evidence -based solution that can overcome the math stagna tions completely within 1 administration using MMU 1 (to raise the worst half math average to the best half math average) or MMU 0.5 (with the half of the capacity of MMU 1) . The highlights of the demonstrations are: 1) New Zealand – along with virtually all other English -speaking developed countries – have been in deep math EDU growth stagnations (and even declines) over the past 15 to 20+ years. 2) Almost uniform math stagnations and declines of all 8 jurisdictions in PISA math 3) A set of solution proposal called MMU 0.5 or 1 (roughly boosting the jurisdiction or national math average by 0.6 - 0.7 Standard Deviation or
