After reading thoroughly the linked article and watch brief lectures, you need to (1) summarize the main arguments (objective description, OD; about 400 words) and (2) construct your reflection on the assigned materials (subjective analysis, SA; about 400 words)

Please keep in mind that:
1) Summary of main arguments = objective description – This is a simple summarization of the assigned article and materials.
2) Your reflection on the assigned materials = subjective analysis, interpretation – This is not a summary, but your own analysis on the article and materials. 

Writing an “objective description” is to summarize the assigned material objectively and value-freely, while writing a “subjective analysis” is to create your own analysis with your own words.
