A lesson plan is a lesson "project" written down on paper. It is only a "project" because a lot of unpredictable events occur in the classroom.It is also a dreaded part of instruction that most teachers detest. It nevertheless provides a guide for managing the learning environment. As one of the teacher's roles is that of designer and implementer of instruction, the preparation of lesson plan will ensure the organization of the English lesson according to some criteria. Regardless of the format, all teachers need to make wise decisions about the strategies and methods they will employ to help students move systematically toward learner goals. The more organized a teacher is, the more effective the teaching, and thus the learning, is. Writing daily lesson plans is a large part of being organized.
Teachers need to have a precise notion of educational goals / objectives / standards / competences
Content is chosen according to the level and needs of the learners. It must be interesting and appealing to them.
The effective teacher also needs to develop a plan to provide direction toward the attainment of the selected objectives. Teachers must decide how to sequence the teaching items according to the methodology and approach they opted for. Sequencing may be from easy to difficult, from known to unknown, from familiar to unfamiliar ...
The effective teacher certainly controls the way time is used. Effective teachers systematically and carefully plan for productive use of instructional time.
There should be some kind of feed back tasks to highlight lesson deficiencies.
Finally, even teachers who develop highly structured and detailed plans rarely strictly stick to them. Such rigidity would probable impede, rather than help, the teaching-learning process. The elements of your lesson plan should be thought of as guiding principles to be applied as aids, but not blueprints, to systematic instruction. Precise preparation must allow for flexible delivery. During actual classroom interaction, the instructor needs to make adaptations and to add artistry to each lesson plan and classroom delivery.
