Dear students,
PPP and TBL are two important teaching models. Please review this part carefully with the instructions and academic resources.
1. PPP


1) Three stages
P: presentation
The teacher introduces a new language item in a context
P: practice
Students are asked to some controlled practice, such as drills, exercises, dialogue reading, repetition.
P: production
Students produce the language in a more meaningful way: role-play, drama, interview
2) Key words
Exposure: Students' exposure to a variety of language
Restrict: Students' exposure to a variety of language is restricted by the teacher (especially in the first two stages). Teachers pre-select the language (forms) to be taught and exercises for students to do.
Instruction: Teachers' instruction takes up a large part of the whole class.
Use (free or partly restricted): In the last stage, students have the chance to practice using the language in a more communicative context. If students are asked to do a task, then they can use the language freely. If students are asked to do an exercise-task, then their exposure to a variety of language is partly restricted by the teacher.
2. TBL


1) Three stages
Pre-task: The teacher will present what will be expected of the students in the task phase.
Weak form: The teacher may prime the students with key vocabulary or grammatical constructs, although this can mean that the activity is more similar to PPP paradigm.
Strong form: Learners are responsible for selecting the appropriate language for any given context themselves. The teacher may also present a model of the task by either doing it themselves or by presenting picture, audio, or video demonstrating the task.
Task: During the task phase, the students perform the task, typically in small groups, although this is dependent on the type of activity. And unless the teacher plays a particular role in the task, then the teacher's role is typically limited to one of an observer or counselor.
planning stage: drafting, rehearsal and practice (help learners adjust their language for the report stage; encourage learners to consider appropriateness and accuracy of language in general, rather than a single form)
report: a free exchange of ideas, summarizing learners' achievements
Post-task:
Analysis and practice: Teachers can analyze the language problems existing in common and guide students to do more practice.
Review: learners can review each other's work and offer constructive feedback.
2) Key words:
Exposure: The exposure include a whole range of words, collocations, lexical phrases and patterns in addition to language forms pre-selected for focus (weak-form in the pre-task stage). Students feel free to use a variety of language and they rely on their own linguistic resources.
Restrict: Students' exposure to a variety of language is only restricted in the post-task stage when teachers help students to analyze common language problems in their report.
Instruction: Teachers' instruction is not the main part of the whole class.
Use: The task supplies a genuine need to use language to communicate and students feel free to use a variety of language. They will realize there is more to language than verb tenses and new words.
