Today, the 'communicative approach' is pretty much everywhere in the language classroom, but teachers and students still don't quite understand the point of it.
Here's a good start:
The Communicative Approach is based on the idea that learning a language successfully comes through having to communicate real meaning. In the Communicative Approach, the main objective is to present a topic in context as natural as possible.
Communicative Approach in TESOL/TEFL (CLT)
And something a bit more academic
The Communicative Approach (CA) – or Communicative Language Teaching
(CLT) –is “an approach to the teaching of second and foreign languages that
emphasizes interaction as both the means and the ultimate goal of learning a language,”
(“Communicative language teaching”, Wikipedia) going so far as to “initially
[prioritize] communicative competence over accurate grammar“ (Hart). This approach
comprises a wide range of methods, not a single, well-defined one, but invariably they
all work towards showing the learners “how we really use language in authentic
discourse” (Davies, Pearse 193-194). In general, CA lessons are built round situations
which are practical and authentic in the real world, e.g. asking for information,
complaining, apologizing, job interviews or telephoning. Consequently, dialogues, that
occur, focus on communicative functions such as socializing, giving directions, or making telephone calls, which all have relevance and purpose in real-life situations,
allowing students to see the direct benefit of learning (Hart).

Here's a good list from Gill Hart:
Gill Hart gives the following 13main core suggestions which make
the CA the most successful language learning approach in use today.
1. A teacher's main role is a facilitator and monitor rather than leading the class.
In other words, "the guide by the side" and not "the sage on the stage".
2. Lessons are usually topic or theme based, with the target grammar "hidden" in
the context e.g. a job interview (using the Present Perfect tense.)
3. Lessons are built round situations/functions practical and authentic in the real
world e.g. asking for information, complaining, apologizing, job interviews, telephoning.
4. Activities set by the teacher have relevance and purpose to real life situations -
students can see the direct benefit of learning.
5. Dialogues are used that centre around communicative functions, such as
socializing, giving directions, making telephone calls.
6. Emphasis on engaging learners in more useful and authentic language rather
than repetitive phrases or grammar patterns.
7. Emphasis on communication and meaning rather than accuracy. Being
understood takes precedence over correct grammar. The fine tuning of grammar comes
later.
8. Emphasis is put on the “appropriacy” of language. What is the most appropriate
language and tone for a particular situation?
9. Communicative competence is the desired goal. i.e. being able to survive,
converse and be understood in the language.
10. Emphasis is put on correct pronunciation and choral (group) and individual
drilling is used.
11. Authentic listening and reading texts are used more often, rather than artificial
texts simply produced to feature the target language.
12. Use of songs and games are encouraged and provide a natural environment to
promote language and enhance correct pronunciation.
13. Feedback and correction is usually given by the teacher after tasks have been
completed, rather than at the point of error, thus interrupting the flow.
