(Continuation from yesterday)

Even so, if there are past data or future prediction analysis (for example "easy regression analysis"), they might be helpful for the readers. But nothing is doing.

It means that "they don't know how to use the EXCEL(spreadsheet)", before "luck of basic math literacy", or "contempt of data".

For example, the annoying operation of "plotting a graph on cross-section paper" is available using not only PC but smart-phone.

From the viewpoint, I think junior school students are going to use smartphone as a "calculator" more and more.

-----

On another note,

Now, "to bring smartphone into junior school" becomes an object of public concern.

I also think that "to use smartphone in school, as a communication device" should deserve careful and thoughtful consideration.

Even if it is true, this problem comes to resolve to cancel the communication function of smartphone. For example, there are technologies,

- "Jammer" that cancel the communication around a specified area,

In addition, if a school installs a private wireless LAN environment,

- "Redirect" that makes all the Internet communication pass through the school server.

The school can make common cause with carriers, and disturb.. correction.. restrict or monitor the students access. (They have already been possible)

Moreover, a school should installs the IT infrastructure positively and strategically, and use IT as a education tool. These activities will make everyone happier.

-----

I think that this is engineer's karma that try to resolve anything by using "technology", however, I also think that these knowledges lose nothing by doing.

Maybe, the time is coming that we have to accept a new paradigm of "a human being is at one with a small calculator (smartphone)".

even if the paradigm shows you "unpleasant world".

Let's go the board.

Data is not all.

Data is just "pre-processing".

Therefore the theory of columns without "pre-processing" data,

is "incredible" for our engineers.
