It’s been keeping online colleges bounding ahead, not only aiding young students to obtain their first Bachelor’s of Science degree, but for seasoned professionals who need to move on to their Masters and Ph.Ds, and just attending online seminars to keep up to date. STEM is a field of perpetual study. It’s also so broad it can use more definition. The best way to start is defining the main categories, i.e. science, engineering, math and tech. According to the Bureau of Labor Statistics (BLS), they are:(1) Natural Science Occupations: These scientists and technicians fall broadly into three key subsets: Life scientists, physical scientists and natural scientist technicians. They compose approximately 13% (752,000) of all STEM personnel. Specialists include agricultural and food scientists, biological scientists, conservation, environmentalists and geophysicists, astronomers and medical scientists. The technicians assist scientists in conducting experiments and analyzing the results, providing the backbone of the process.
