What Changes in Secondary 2?

Students increasingly need to explain relationships between ideas, compare choices and support conclusions. The vocabulary becomes more analytical while remaining high-utility and readable.

Secondary 2 G2 Essential Practice

At Secondary 2, move beyond recognition into comparison and judgement. Select ten words and complete four checks: explain the meaning, use the word naturally, contrast it with a nearby word, and apply it to a new situation. Keep a word in review if any one of those checks remains uncertain.

Analysis and reading

Use words such as factor, context, perspective, significant and evidence carefully. A factor may contribute to a result without being its only cause. A perspective is a way of viewing a situation, not permission to alter the facts. Significant should identify something that matters to the interpretation rather than merely something noticeable.

Writing and reasoning

Practise building a short chain: claim → relevant detail → explanation → conclusion. Then test whether the conclusion is stronger than the evidence permits. Words such as evaluate, rational, sufficient and reliable become useful when the sentence makes the criterion or reason visible.

Speaking and collaboration

Discuss a practical school decision with a partner. Each speaker should state a viewpoint, acknowledge one competing factor and recommend an action. Use vocabulary naturally rather than forcing a fixed number of target words into the response.

Collocation, editing and transfer

Check the words around the target: capable of, concentrate on, depend on, relevant to, responsible for. After correcting an error, create a different sentence using the same pattern. This distinguishes genuine transfer from memorising the correction.

Vocabulary Flight Deck

Choose twenty words at random. Explain each one, write a new sentence, contrast it with a nearby word and use it in a short spoken response. Repeat until the full list is secure.
