This is much better! The word "make" is fine in this sentence. I think this is ok for use in an academic essay.
Just three adjustments to your work.
Being a primary school teacher is an exhausting job that requires a lot of concentration. This age group is so energetic and active that you will need to be at least as dynamic as the students. [strike]This[/strike] will [strike]possibly[/strike] make them motivated as well as meet their minimum educational requirements.
I would remove the word "possibly". It is not a grammar problem. However, what it does is weaken the strength of the sentence. By adding "possibly" to the sentence, you are saying that you think what you are saying is true, but you are not 100% certain of it.
Note that I have highlighted the two sentences starting with the word "this". You should not start two sentences in a row like this. One "this" should be changed and I vote for the second one because the last sentence should be changed.
This will possibly make them motivated as well as meet their minimum educational requirements.
This sentence refers back to the previous sentence where you discuss the need for the teacher to be "dynamic". As you point out, this would keep the children motivated. However "meet their minimum educational requirements" does not relate to being "dynamic". Do you see what I mean? I could be a teacher who was very energetic and dynamic in my approach but fail as a teacher because I did not teach them anything.
What I suggest is that you take that first part of the sentence and create a subordinate clause that would be used in the previous sentence (this also eliminates the second "this" problem). Then write another sentence where you comment on meeting minimum education standards.
