What is project work? Project work, as used in this book, can be defined as a full implementation or a third generation task. Although the duration of a task may vary (in its simplest form it may cons basic structure), a project is, by its nature, longer and more complex. Like a novel, which consists of chapters and episodes, a project is a large task (macro-task) composed of smaller steps (micro-tasks), which are described separately in each of the sections of this book. Each step is a task in its own right and, as such, can be expanded or reduced. What all this means is that, once started, the project becomes a world in its own right. The sequence of events is flexible and both teachers and students are involved in making decisions throughout. We may decide to stay on the main road and go directly to our destination (end product) or alternatively explore slowly all the side-roads (sub-topics) we discover along the way. Steps, time-span, product and process are, of course, pre-planned in the teacher's mind, but not totally predetermined. They are also class generated, and so they have to be flexible and negotiable. So, while a project has a pre-planned beginning and an end, it is usually so rich in possibilities that exploring all its side-avenues can turn it into a real 'Never-ending Story" Factors such as group dynamics, enthusiasm, level of interest, difficulty, and relevance, etc., will all influence our decision to stay on the chosen route, to take a shortcut and accelerate the process, or to slow it down and spend extra time on a certain stage we particularly enjoy. What does project work involve? The sequence of steps in a typical project are fully described in the following chapters of this book. They constitute the signposts or the visible structure of the project However, from the language learning/acquisition point of view, there are a number of elements which, because of their presence throughout the project, should be described briefly here. Project work, like other activity-based learning processes, tends to be fun and engaging However, language learning requires more than that. Conditions for learning include the processing of large quantities of what Krashen called comprehensible language input and also what Swain called comprehensible language output. If these are lacking the students go round in circles, using only the language they already know, without pushing towards a new level of proficiency. This kind of circularity happens when a task does not create new language needs nor provide students with the means for meeting them. Therefore, need tasks that are not only challenging in terms of content but we also in terms of language. They should contain three basic elements
