My students and I worked on this question from Cambridge IELTS 9:
Some experts believe that it is better for children to begin learning a foreign language at primary school rather than secondary school. Do the advantages of this outweigh the disadvantages?
Here's our plan for a 4-paragraph essay:
- Introduction: Topic = best age to learn a foreign language. Our opinion = better to learn at primary school age.
- Disadvantages of learning languages at primary age: other subjects are more important at that age (maths, mother tongue language, science), learning a new language is confusing and wastes time, could delay development of child's first language.
- Advantages of learning languages at primary age: young children learn faster, they are less self-conscious or shy, they pick up the pronunciation better, they enjoy copying and learning through games, nowadays languages are just as important as maths etc.
- Conclusion: repeat / summarise our answer.
The plan took us 10 minutes to write. With a plan like this, it should be easy to write a good essay in 30 minutes.
