Hi Yifei, IB Command terms are for the international baccalaureate, right? STATE - To give an answer or response without an explanation = e.g "Do you like fruit?" "Yes" = to state = make a statement OUTLINE - To give a brief (short) draft/ summary/ a list of something.= e.g "I want an outline of everything that happens in the movie" "The movie follows two men on a journey across America, first they go to Las Vegas, then California and finally to New York" DESCRIBE - To give a lot of detail and information on something = e.g "Can you describe what you see?" "I see a park with lots of children running around, the park has a slide which is blue and green" SUMMARIZE - To, in your own words, explain the main idea, concept, plan, theme from something (paraphrase), NOT just re-wording. = e.g "I want you to summarize this academic paper for homework" "The writer talks about language learning and the problem with classrooms, specifically, why both have disadvantages and advantages" STATE --> OUTLINE --> SUMMARIZE --> DESCRIBE (this would be the order from least detail to most detail) Hope this helps. I found this website with some IB terms, https://www.binghamton.edu/gse/teacher-education/pre-service/edtpa/command-terms-IB.pdf
