Yes. Thing is everyone thinks they know English as a subject. Studying it at any level requires critical thinking plus creativity - writing essays, etc.
I am amazed the primary curriculum was shaped by a mathematician- it’s as though they have tried to teach English as function in the way maths works. I get that you need to understand the formal linguistic elements and support that but we are not integrating it with how it is used and often distorted. We are focusing so much on the detail, we lose the bigger picture and it is that which pupils are often able to grasp conceptually.
I feel we have butchered it, actually. I know that not every child will love reading but we have to start from the premise that wise reading is crucial - not formulaic texts. Then we can move onto issues of comprehension, meaning, manipulation of language.
In a time of fake news, critical thinking skills are key yet we treat media studies (that looks at advertising, bias, etc) as a poor choice. If you are academic, then you will cover those ideas in English and ‘get’ it but for those who aren’t academic, the emphasis is on the practical, with very little critical.
