Apparently, there is a raging debate between task-based learning and present, practise, produce. These are referred to as TBL and PPP.
What is PPP?
With PPP, the teacher presents some language. Students practise it with drills or exercises and then move on to general language production, where they may attempt to use the new structure.
What is wrong with PPP?
One of the problems associated with PPP is that students can't remember what they learned a couple of weeks later. To that, I say, of course they can't. They can't and won't remember anything if you don't revise it regularly.
A second problem with PPP is that students may overuse the new structure and sound unnatural during the production stage of the lesson. To that, I say, so what? It's a lesson, they are practising, and showing they know how to use it. Sounding natural comes after a LOT of production. Take a jazz musician; she has to know her scales. If she doesn't...she won't be able to improvise in a given key. Are you going to tell a musician not to practise scales because they sound unnatural? Scales are drills; they aren't music, but practising them increases fluency and finger technique, so you sound more natural when you improvise.
The third, terrible, problem with PPP, is that students may not produce the target language during the free practise stage because they use other language instead. There are ways fun ways around that. Get students to work with the new structure in inventive ways, like having to include it in a dialogue using different expressions (sad, laughing, angry), playing games with synonyms, including it in quiz questions or pairwork games.
What is TBL?
By contrast, in a task-based lesson, the teacher doesn't pre-determine what language will be studied. Students perform a task, and the lesson evolves around what crops up. That is a great way to teach, especially with intermediate students and up, but what do you do if you have a unit with some specific grammar to get through and your students don't use it! (But why would they, if you never presented it to them?)
The so-called pre-task is where the teacher introduces the topic and helps students recall some language that may be useful for the task. I may be splitting hairs, but this sounds like the presentation phase of a PPP lesson. The TBL lesson continues with pairwork, group work, and feedback from the teacher - all of which happen in the production part of a PPP lesson too...for me the production part of a PPP lesson includes comaparing, debating, on-the-spot thinking, and creating.
That said, academic nit-picking can be useful now and then, so teachers don't get stuck in their ways. So, rather than debate that one formula is better than another, I recommend teachers vary their approach and give different types of lessons. Keep your students surprised and stimulated. If you go through the same-old-same-old every single class, it'll become dull.

These books of games are sure to help you give varied, fun lessons, with students participating fully. You'll find some great PPP games for beginners. After all, you can't expect students to debate in groups when they have no vocabulary or grammar. For beginners, it is helpful to present language in "neat little blocks." Get comfortable with those little blocks, and build. In the books for teens and adults, and the online games books, you'll find lots of task-based learning activities and games. For example, getting students to prepare for a quiz, make a board game, make a short film in groups, conduct research through interviews, write reviews for films, design a recipe, prepare a map, prepare for a meeting or prepare a biography for a famous person guessing game. Lots of games in the books can be prepared for as a task in or before class.
