Firstly, I think that you are absolutely right. Good scriptwriting is an essential tool in keeping the lessons interesting and entertaining for students.
I am a graduate from a well-known British drama school, so I have excellent experience in working with scripts and possess an well-thought out understanding of how language and grammar work. Whilst my degree was mainly practical, I was also required to undertake academic tasks including fully referenced dissertations and essays whilst retaining academic integrity. My scores in the academic portion of my work reflect my attention to detail and love of the English language. I was the highest scorer in my area of study for almost all assignments and my average was 80.25 (1:1, first class). Additionally, I was an accomplished scientist at college, earning 'A' grades during my GCSEs in Physics, Chemistry and Biology.
Initially, I would cut the stages of photosynthesis into short scenes, noting down visual ideas. Once done, I'll begin work on the dialogue and make certain the level of language is age-appropriate. I will also work through each episode as spoken word l to ensure that the dialogue lives off the page as well as on! Regarding, the style of English used, I am perfectly capable of writing UK or US/International English, I would be guided by you.
If you'd like to discuss this further with me, please feel free to contact me through the site.
