IMPLEMENTATION STAGE

Different strategies can be used to implement this lesson. All these strategies, inductive, deductive etc, have shared vision for a common goal; the most effective and efficient style or a method that I can present the subject matter in order to maximize the student learning capability. For this lesson I used the inductive method compared to traditional teaching strategies. Inquiry strategies, problem based-solving, discovery learning is the different instructional method that I used to implement my lesson.
For this particular topic, I decided to use two inductive teaching methods, namely inquiry based learning and discovery learning.


The steps I followed to conduct my lesson are explained.

Step 1 (3mins)
The word material was written on the whiteboard.


Step 2 – 8 mins
Students were allowed to think individually about the word for five minutes, with word related to material written on their copybooks. I walked around during those five minutes to have a glance at their work. This part of the lesson was intended in order to allow those students, with many learning difficulties to develop their thinking skills. Words written by the students included macadam, ferraille, tournevis, marteau, ciment, clou etc

Step 3 – 10mins
A precise explanation was given  on the blackboard of the word material, supplemented by pictures, flipchart, magazines and real small objects (compass, match box, glass, toilet paper, calculator, gravel, newspaper etc)    brought by me.

Step 4 – 10mins
 Students were directed to write all notes on their copybooks and to reflect on them for questioning. At this stage of the lesson I told students to relate what have been learnt to their immediate environment. I also asked the students how much time they needed to carry this task so as to allow them to grasp all relevant information.  
I used this approach of mutual agreement, so as to boost the confidence, responsibility and trust towards the teacher, of the students.

Step 5 – 10mins
Then I asked students to direct any question to me in order to clarify any point, word, or materials of the lesson so far conducted. This was carried out by the students raising their hands and the teacher attending one by one. The method employed was oral questioning, oral answering, visualizing, and handling.
