As the 2020 election cycle ramps up, voters can expect a flurry of targeted advertisements fueled by big data on their doorsteps, inboxes and social media feeds. While microtargeting based on demographic information is not a new trend in campaign strategy, campaigns traditionally relied on analyzing voter behavior within broader categories such as age or gender before big data was easily accessible.
Chipmunk Error Evaluation
Getting children doing error evaluation in math class has been vastly helpful, this yr. I’m beyond-words thrilled that I’ve stumbled throughout this method to get sixth graders analyzing, discussing, and writing multi-paragraph, considerate explanations (!!) of pupil errors and why they occur.
We did a second go-round of weblog posts / error analyses utilizing the identical methodology as final time, however I supplied up a unique batch of errors.
This time, Alvin, Simon, and Theodore (har, har…) had been the scholars in want of assist. Every chipmunk encountered a unique, distinctive drawback when making an attempt to do multiplication (of fractions and decimals) and lengthy division (with two-digit divisors).
Alvin doesn’t change the blended numbers to improper fractions:
Simon is obsessive about lining up decimal factors – in addition to the usual algorithm for including decimals:
Theodore forgets zeros within the quotient:
Be at liberty to make use of these errors to drum up dialogue in your classroom! Making children write concerning the errors isn’t compulsory – however I believe it had a big impact on retention. Additionally, I’m seeing my children get higher and higher at finding errors, pondering up the explanation why college students may make errors, and articulating their thought processes. Hurrah!
