In the reality it does not matter how well the kids do on the tests or if they are "proficient" according to some curriculum. What matters is if they have qualifications to do the job and that is an aboslute measurements. If they do not know how to solve linear equations and ascertain where they are or not applicable and I need people who have this capability I will not recommend them being hired.
On that note mathematics is taught atrociously bad in US, the progress of instructions does not make much sense, the math is presented as a set of disjointed ideas without enough facility to either do the theory or the practice. Yes, the functions are good but a lot of people will need just fractions, percentages and arithmetics and they still cannot do it! The calculators in their hands are as good as swords, you cannot use them if you do not understand what for!
I am not even sure what kids know or not anymore. It is summer and high schoolers and undergraduates work in supermarkets. Just recently I needed to identify, name and spell to the seemingly otherwise bright kid manning the cash register the following: dill, horseradish, scallions, parsley, garlic and I forgot what else .. This happenned to me many times ... The kid bagging the stuff did not know eiether. But their self confidence levels were burning holes in the roof ...
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
