As a language teacher, what should be your primary aim of language teaching?

What do 'form-oriented language inputs' primarily refer to in language learning?

What is the following classroom task known as? 'A small piece of text is divided into two different chunks (e.g., alternate sentences). A pair of learners work together where each learner dictates their part to the other while the partner writes it down. This process is reversed so that both listen and write, and they later work together to reconstruct and finalise the whole text.'
