I was taught about significant digits in Junior High School science classes. (in a public school in US, late 1960s.) Answers were marked wrong if they had too many digits that weren't significant. Is this no longer taught in school?

- atkion 3y agoThis was definitely still taught in my public high school in the 2010s - if they stopped teaching this, it was very recently. Granted, the teacher that tried to teach me this had no understanding of it themselves and would incorrectly mark answers wrong when they had the correct number of significant digits, so it was pretty botched in my case. Still was attempted in the curriculum though.
- 2muchcoffeeman 3y agoI think some of the problem is that you can get into computing through many pathways now, and you don’t have to come through some science and math stream from high school. Even when I was doing physics I always had to remind myself of the accuracy.
- koito17 3y agoSignificant figures have always been taught in chemistry courses. I remember students getting confused at notation like "100. g" representing 100 grams with 3 significant figures.

- bluenose69 3y agoI was taught this in High School and I know that it is still taught. We learned it because the option for such (and many other) errors was a zero on the work and likely an F in the class overall. Teachers have a lot less latitude nowadays; see [1] for an example that is shocking in the 1960s context. 1. https://www.cbc.ca/news/canada/edmonton/teacher-who-gave-zeros-won-t-appeal-suspension-1.1184970 https://www.cbc.ca/news/canada/edmonton/teacher-who-gave-zer...
