If indeed grammar and spelling scores are higher now (and I'll assume that's true because Randall usually does his research well), maybe it's because:
* We're teaching kids better?
* The tests are different or graded differently?
* The population has shifted?
You're missing the point. The argument is not that texting improves grammar; the argument is that texting does not (contrary to some popular opinions) ruin grammar. The causation is irrelevant. Correlation may not imply causation, but a lack of correlation can often rule out any causation. And what we see here is a lack of correlation between texting and bad grammar.
