(ESPCEX) We’re so well educated – but we’re useless

Record numbers of students have entered higher education in the past 10 years, but despite being the most educated generation in history, it seems that we’ve grown increasingly ignorant when it comes to basic life skills.

Looking back on my first weeks living in student halls, I consider myself lucky to still be alive. I have survived a couple of serious boiling egg incidents and numerous cases of food-poisoning, probably from dirty kitchen counters. Although some of my clothes have fallen victim to ironing experimentation, I think I have now finally acquired all the domestic skills I missed out in my modern education.

Educationist Sir Ken Robinson says that our current education system dislocates people from their natural talents and deprives us of what used to be passed from generation to generation – a working knowledge of basic life skills. Today’s graduates may have earned themselves distinctions in history, law or economics, but when it comes to simple things like putting up a shelf to hold all their academic books, or fixing a hole in their on-trend clothes, they have to call for help from a professional handyman or tailor.

Besides what we need to know for our own jobs, we must have practical skills. We don’t grow our own crops, build our own houses, or make our own clothes anymore; we simply buy these things. Unable to create anything ourselves, what we have mastered instead is consumption.

Sociologist Saskia Sassen argues that the modern liberal state has created a middle class that isn’t able to “make” anymore. I suggest that we start with the immediate reintroduction of some of the most vital aspects of “domestic science” education. Instead of only maths, language and history, we should create an interactive learning environment in schools where craftsmanship and problem-solving are valued as highly as the ability to absorb and regurgitate information. We need to develop children into people that not only think for themselves, but are also able to act for themselves.

In the sentence “I think I have now finally acquired all the domestic skills I missed out in my modern education.” (paragraph 2), the words missed out mean:

Na figura, estão representadas as trajetórias de dois projéteis, A e B, no campo gravitacional terrestre. O projétil A é solto da borda de uma mesa horizontal de altura H e cai verticalmente; o projétil B é lançado da borda dessa mesa com velocidade horizontal de 1,5 m/s.
(O efeito do ar é desprezível no movimento desses projéteis.)

Se o projétil A leva 0,4 s para atingir o solo, quanto tempo levará o projétil B?

O trabalho infantil ainda faz parte da realidade brasileira e também de muitos outros países do mundo. Pensando nisso, explique o significado da frase que ilustra este cartaz.



(UDESC) Em 1942, Ernst Mayr (1904 – 2005), biólogo alemão e um dos maiores evolucionistas de nossa época, propôs a seguinte definição: “um grupo de populações cujos indivíduos são capazes de se cruzar e produzir descendentes férteis, em condições naturais, estando reprodutivamente isolados de indivíduos de outras espécies”.

A definição proposta por Mayr se refere ao conceito de:
