Answer:There is a lack of clarity in the lesson presentation.
Step-by-step explanation:
The lesson presentations is supposed to flow in a way that students are able to follow along because there is a pattern that each step lead to the next and it should engage them in such that they feel as part of the lesson rather than spectators who are looking at the movie presentation.
Mr Sains mixes different topic one moment he is discussing chemistry symbols next moment he is referring to the work that will be done in the next six month and most of what he talks about seems very irrelevant to each other that it may confuse students.
A lesson presentations is supposed to be about the lesson of that day , engage students , test their understanding of the new concepts and tackles whatever issues they have with that day lesson. It should bring clarity to students as they follow it.
