Mr. McInally's editorial (Opinion, Feb. 23) perpetuates the mantra that if we just spend more money we'll get better educational outcomes. A 50-state, scatter plot of public school revenues per pupil versus 8th grade math test scores in 2015 shows the following details:
• There are 14 states that spend less that Oregon and get better scores.
• There are 7 states that spend more money that Oregon and get lower scores.
• There are 12 states that spend more than Oregon and get better scores.
• There are 15 states that spend less than Oregon and get lower scores.
• The simple correlation coefficient of these two metrics is 0.13658. So more money is a very poor predictor of outcomes.
GAPS' low test scores result from the script/methods that GAPS administrators require teachers to use. The teachers really do want students to succeed. The methods currently used in "common core" must be abandoned to achieve better outcomes.
Zero-cost administrative changes are more likely to advance learning than more money.
