Dear Benny! You are right! Many people are using it; however, most educators either do not use it or use it by connecingt it with other "doable" verbs like "LISTEN and REPEAT after the teacher" are connected.
I was disappointed that after listening to all the background information, the professor did not give a single example of how to actually write an effective learning outcome, which was the title of this RU-vid video and the reason I watched it.
Some schools of thought reject the idea of using "understand," in an objective while others embrace it. This concerns me as I see it as an open ended objective to measure a students level of understanding- deep, superficial or intermediate. This rubric would be established by the intangible aspects of a learning audience- prior knowledge, region socio-economic background, age, vocabulary, attention and so on. I wish I knew this as absolute. It makes very confusion when there is such a rift in basic ideas of writing objectives. What do you think?
