While 42 states require public school students to take a sexual education course that covers at least one topic within this subject between kindergarten and high school, only 19 states mandate that this instruction be medically accurate—and 5 of those states only require medical accuracy for specific topics, according to a new study in the American Journal of Public Health. The study also found that 34 states that mandate sexual education in public schools require instruction on abstinence, a method that has consistently proven to be ineffective or harmful to adolescent sexual health, but continues to be embraced and funded by the federal government. Thirty-four states also allow parents to opt their children out of receiving any sexual education instruction, while five states require parents to opt in for their children to receive this instruction. 

This study explores what pre-service teachers from India and Sweden notice in a Japanese classroom video. The findings reveal how familiarity with mathematical procedures supports detailed noticing of mathematics discourse. The unfamiliar teaching practices prompted discussions and offers learning opportunities. To incorporate culturally contrasting examples in mathematics teacher education has the potential to deepen teachers’ reflections on teaching and contribute context-sensitive awareness.

A new study by USC Leonard Davis School of Gerontology researchers shows that Americans with less education are aging faster than their peers with more schooling, and the gap has grown over the last 30 years.

The study examined “biological aging,” which goes deeper than simply counting birthdays. Biological aging measures how the body is changing over time, including how well organs and systems are working.
