You will need to consider two important aspects of distance education in science before enrolling in a program: first, you will need to decide what area of science you want to study, as there are many specific areas and degree programs that will vary significantly depending on your interests. Second, you will need to research how distance education in general works, and settle on a distance education in science program that works well for your needs and your budget. Distance coursework is great for people who work full-time or who cannot travel to an on-site classroom, but it will very often require the student to participate in more self-directed learning.
Beyond the most obvious choices for studying science, other options are available for a student who wants to pursue distance education in science. One can study biology, chemistry, and so on, but students may also choose to study science education, bio-engineering, chemical engineering, and so on. Be sure to research the options carefully, as many colleges and universities will offer different programs that may suit you better than another option. "Science" is a broad category, and very few colleges will offer a program that vague. Narrow down your interests and your strengths and choose a program accordingly.
Distance education in science will be taught mostly on the Internet, though other communication methods are available. Be sure to research how each program you are considering is set up for instruction: some online courses take advantage of message boards only, meaning your communication with the professor and other students will be limited to this message board or e-mail. Other courses take advantage of current technologies, and it is common for a class to be taught through streaming media, web seminars, audio and video downloads, and so on.
Applying for a distance education in science is similar to applying to other on-site programs, and you will need to obtain your high school transcripts, as well as any college transcripts if you have any. Most programs will require you to fill out an application, and there is very often a fee associated with this application. Be sure to check what these fees are, and if you are applying to more than one program, be sure you can afford all the application fees. Remember that applying does not guarantee you a spot in the program, so it is best to have a back-up plan for your distance education in science.
