She was urging teachers to check homework, because if they don't, students will be "indifferent to the need for doing it" (and of course, that means a harder job for parents trying to instill good study habits).
The newsletter is also a time capsule of what was happening in that school (and in education) at that time. In addition to "open school week" in November, there was a December PTA meeting to discuss science education and the "new S.R.A. reading kits."
I remember those S.R.A. (Science Research Associates) kits--self-contained units with a page or two of a reading excerpt, followed by multiple-choice questions to test comprehension. All self-paced, and different cards for different reading levels to encourage students to challenge themselves. It was a new idea at the time, being tested in 6th grade classes, thanks to a PTA donation.
Other articles talked about outstanding students, open enrollment, Trick or Treat for Unicef, community improvement, and other issues.
