c. Task Types

Pattinson 1987 in Nunan 2004 sets out tasks and activity types into seven categories. a Question and Answers These tasks can be used to practice almost any structure, function, or nation. These tasks are based on the idea of information gap activities by allowing the learners to make a personal and secret choice from a list of language items that all fit into the given frame. b Dialogues and Role Plays These tasks can be totally scripted or totally improvised. However, the improvised dialogues or role plays are preferable since learners will participate more willingly and learn more thoroughly. c Matching Activities These tasks require the learners to recognize matching items, or to complete pairs or sets. d Communication Strategies These tasks require the learners more likely to practice communication strategies such as paraphrasing, borrowing or inventing words, using gestures, asking for feedback, and simplifying. e Picture and Picture Stories Pictures can be used as an input in these tasks. It can be memory tests or sequencing pictures to tell a story. f Puzzles and Problems In these tasks, the learners are expected to make guesses, draw on their general knowledge and personal experiences, used their imagination, and test their logical reasoning.
