No, teachers cannot make extroverts out of introverts, but your boss will not accept the fact that you cannot do group work because you find it difficult to work with others. Collaboration creates the best ideas; workplaces that promote synergy are the most productive and effective. If we do not prepare you for this in school, then we are not preparing you for the real world. It is better to try to overcome whatever fears you have in a safe environment where teachers are there to support you than try it where your career is on the line. This is why teachers try to provide a range of options (like independent, group, written, creative, etc) throughout a course for students to play to their strengths for at least one point, and then challenge themselves for other portions. If one isn’t challenged to try things that make them uncomfortable, what is the point in being on the planet? Life would get pretty boring.
If you are feeling stressed, talk to your teacher. They are there to support you. Just remember that other people are better in group work than independent work, so group work helps them succeed, whereas they are challenged and uncomfortable when they can’t bounce their ideas off of other people in an independent assignment. Don’t assume extroverts can handle everything, since introverts cannot either.
