1) From the demonstration of the example text and changable coloring of the words and the explanation of how can vocabulary profling could be use effectively in teaching language department provided a light in my understanding. As the video stated we can focus on green and yellow/orange highlighted words to start with teaching as the reason the video stated uncommon words are favored by the teachers more than more frequent words or rare types. I could as a teacher before bringing a reading material to my students check for the types of the words, whether they are common or rare, I could make an assumption about my observations of students' capacity from inclass discussions then I would choose the specific uncommon or common words that I would want them to add to their developing vocabulary skill.

3)The main difference between a word cloud and  vocabulary profiler, in my point of view, is word cloud concentrates on only showing keywords of reading material to encourage students' meaningful learning through seeing a few significant words on the other hand vocabulary profile has a wider usage for mainly teachers, it lets teachers to plan a vocabulary oriented lesson and in a way provides an aidance in choosing which words students should add to their knowledge in that lesson.I would use a word cloud when an instructor of mine assigns me a research paper reading and initially I would look at the keywords the author of the research paper emphasized more, it can gvie me a starting thought about the research paper..I would use vocabulary profiler when I become a teacher to aid myself in planning a thoughtful choice of words to teach my students
