I am a physics teacher. Or, at least I used to be. My subject is still called physics. My pupils will sit an exam and earn a GCSE in physics, but that exam doesn’t cover anything I recognize as physics. Over the past year the UK Department for Education and the AQA board changed the subject. They took the physics out of physics and replaced it with… something else, something nebulous and ill defined. I worry about this change. I worry about my pupils, I worry about the state of science education in this country, and I worry about the future physics teachers — if there will be any.Este excerto é o início de uma carta que um professor do ensino secundário inglês escreveu aos seus superiores hierárquicos.

Tem passagens muito interessantes que se podem aplicar na perfeição aos novos programas de Físico-Química, em Portugal, de onde a matemática parece ter sido banida, transformando as ciências exactas em disciplinas meramente "descritivas". Repare-se no excerto seguinte:
The thing that attracts pupils to physics is its precision. Here, at last, is a discipline that gives real answers that apply to the physical world. But that precision is now gone. Calculations — the very soul of physics — are absent from the new GCSE. Physics is a subject unpolluted by a torrent of malleable words, but now everything must be described in words.
In this course, pupils debate topics like global warming and nuclear power. Debate drives science, but pupils do not learn meaningful information about the topics they debate. Scientific argument is based on quantifiable evidence. The person with the better evidence, not the better rhetoric or talking points, wins. But my pupils now discuss the benefits and drawbacks of nuclear power plants, without any real understanding of how they work or what radiation is.
