A way to teach reading that emphasises understanding the meaning of words from the context in which they appear is:

The correct answer is Whole language approach.

Explanation:
Let us break down the different educational approaches to teaching reading to understand why the Whole language approach is the correct method that emphasizes understanding the meaning of words from their context:

1. Whole Language Approach: This approach is a method of teaching reading that emphasizes learning to read through experiencing and understanding words in meaningful contexts (such as complete sentences, stories, and real-world texts) rather than in isolation. It focuses on the relationship between letters and sounds within the flow of reading, helping learners deduce the meaning of unfamiliar words using contextual clues and their overall comprehension of the passage.

2. Structural Approach: This approach focuses on learning the structure or grammatical patterns of sentences and words in a systematic, structured sequence. It emphasizes linguistic structures rather than relying on meaning from contextual reading.

3. Communicative Approach: Mainly used in language acquisition, this approach focuses on developing the learner's ability to communicate effectively in real-life situations. While interactive, it is a broader pedagogical framework for language learning rather than a specific reading instruction method focused on word-meaning deduction.

4. Bottom-Up Approach: This method views reading as a linear process that starts with the smallest unit of language (letters/sounds) and moves upward to syllables, words, sentences, and finally, comprehension. It emphasizes phonics and decoding words in isolation before understanding them in context, which is the opposite of emphasizing meaning-making from the overall context first.

Therefore, the approach that teaches reading by focusing on understanding word meaning directly from the context in which they appear is the Whole language approach.
