@joboaler Two knee-jerk hypotheses:

Districts are struggling more and more to provide funding for high quality PD

Teachers are burnt out in higher numbers and not wanting to spend more time in work-related activity

[J. Clayton Riley @RileyMathClass]

She also noted that students had a more positive attitude towards math class when they were able to use calculators.

Thoughts?

A good night's sleep and a return to the research this morning has produced some interesting results. I think the fear of calculators in the classroom is stigma not based in fact. #mtbos #iteachmath

Good evening #MTBOS, #iteachmath, etc, I'm a high school math teacher and have found myself more and more in the camp of "using calculators is eroding number sense." (1/3)

A meta-analysis by Aimee Ellington in 2003 found that calculators "did not hinder the development of mathematical skills" but actually improved problem solving when calculators were used in class and during tests.

I've struggled to find sound, quantitative analysis supporting or debunking this hypothesis of mine. Would any of y'all happen to know of research showing an increase or decrease in number sense, mathematical fluency, etc. while using calculators vs. not? Preferably HS. (3/3)

[J. Clayton Riley @RileyMathClass]

This afternoon I've wondered if that is actually the case, or if this is just some baseless opinion adopted by me and many other math teachers. (2/3)

What do these percentages mean? The explanation coming soon in Statistics at AHS

Great example of how a skewed distribution (skewed right in this case) pulls the mean away from the median. Your measure of central tendency matters!

@robertkaplinsky One of the best activities of the year seeing students create quadratic functions before even teaching it!

[J. Clayton Riley @RileyMathClass]

Fueling curiosity and awe in the next generation.

Statistics students at @AledoISD simulated aerial wildlife surveying to kick off our lesson on sampling! #GrowingGreatness #AllInAledo

@MrCorleyMath @Meta Agreed! I’m not a fan of thinking Zuck is the winner in all this. Maybe Twitter gets sold again and it’s fixed, or maybe Mastodon is the answer. *shrug*

[J. Clayton Riley @RileyMathClass]

2 Twitter accounts and it’s interesting how much more discussion there is in personal network compared to professional about @Meta Threads. I have noticed that there’s no hashtag so it may be hard to find conversations like #mtbos or #thinkingclassroom. Maybe I’m missing it.

[J. Clayton Riley @RileyMathClass]

@druinok I feel like there are some content leaders that need to make a decision so we aren’t all on 10 different platforms.

#GrowingGreatness with a #thinkingclassrooms warm up for @aledoisd students attending @Knowsys PSAT prep this week. @pgliljedahl
