Formal education begins in school are institutions established to design total learning activities appropriate for each learner in each grade level Thus schools have recommended curriculum which is the enounced K to 12 curriculum. The recommended curriculum was translated into written curriculum like books, modules, teachers' guides and lesson plans which are the basis of the taught curriculum. A teacher who implements the curricula needs support materials (support curriculum) to enhance teaching and learning so that the written and the taught curricula can be assessed (assessed curriculum) in order to determine if learning took place (Learned curriculum) However, there are so many activities that happen in schools but are not deliberately planned. This refers to the hidden curriculum
A classroom teacher plans, implements and evaluates school learning activities by preparing a miniscule curriculum called a lesson plan or a learning plan. The teacher then puts life to a lesson plan by using it as a guide in the teaching-learning process where different strategies can be used to achieve the learning objectives or outcomes. There are many styles of writing a lesson plan, but the necessary parts or elements such as (a) Learning Outcomes (b) Subject Matter (c) Teaching -Learning Strategies, and (d) Evaluation or Assessment should always be included.
All of these elements should be aligned so that at the end of the teaching-learning episode, learning will be achieved with the classroom teacher as a guide.
