Adjuncts: An obstacle to remedial education?

Liz Willen in The Hechinger Report lists one reason community college students can’t seem to catch up in remedial classes:

More than half of community-college courses are taught by part-time, adjunct professors who typically make $1,000 to $3,000 per course and who don’t get benefits.The widespread use of adjuncts has led to questions about the quality of adjunct faculty, who are largely untenured and often have little to no training in or experience teaching remedial classes.
