1. Contrast structure: The answer starts with a contrast, "Not always, to be honest. While peer learning has its benefits, there's a risk..." This shows the ability to present balanced arguments, which is important in IELTS Speaking Part 3.
2. Modal verbs: The use of "might" and "could" demonstrates the ability to talk about possibility and uncertainty, which adds nuance to your answer.
3. Conditional clause: "Without proper adult guidance, they could end up learning things the wrong way." This is a good example of a conditional sentence, showing complex grammar.
4. Infinitive of purpose: "to make sure kids are learning the right skills" uses the infinitive form to express purpose, which is a useful structure for IELTS answers.
