2. Objectives It is very important to state explicitly what you want students to gain from the lesson. Explicit statements here help you to:
(a) be sure that you indeed know what it is you want to accomplish,
(b) preserve the unity of your lesson,
(c) predetermine whether or not you are trying to accomplish too much, and
(d) evaluate students' success at the end of, or after, the lesson.
Objectives are most clearly captured in terms of stating what students will do. However, many language objectives are not overtly observable and therefore you may need to depart from strictly behavioral terms for some objectives. Try to avoid vague, unverifiable statements like:
Students will learn about the passive voice.
* Students will practice some listening exercises.
* Students will do the reading selection.
* Students will discuss the homework assignment.
You would be unable to confirm the realization of any of these sorts of abstruse, loosely stated objectives. The objectives in the sample lesson plan at the end of the chapter are the sorts of statements that you can turn back to after a lesson and determine, to some extent anyway, how well students accomplished the objectives. In stating objectives, distinguish between terminal and enabling objectives Terminal objectives are final learning outcomes that you will need to measure and evaluate. Enabling objectives are interim steps that build upon each other and lead to a terminal objective. Consider the following examples: Terminal lesson objective:
* Students will successfully request information about airplane arrivals and departures.
Enabling objectives:
• Students will comprehend and produce the following ten new vocabulary items.
• Students will read and understand an airline schedule.
• Students will produce questions with when, where, and what time.
• Students will produce appropriate polite forms of requesting.
You may be able to identify a number of other enabling objectives that will vary depending upon what students' proficiency level is and what they have already learned in the course. For another example, notice the difference between terminal and enabling objectives in the sample lesson plan.
