Online courses offer many convenient, work-from-home, and independent learning opportunities. There are many courses being taught online. Difficult courses are being taught that require complex problem-solving, and theory experimentation; here’s why these science and math courses should not be taken online.
Traditional science courses taken in the classroom require the instructor to lecture on principles of biology, chemistry, and physics as well as practice applying those principles and theories in the lab in order to learn the process of experimentation. Traditional math courses give you complex equations, algorithms, geometric probabilities, and many structures of numbers which require the instructor to teach you a step-by-step guide to solving the mathematical problem, and then you are given the time to practice completing a problem yourself in order to solve for the correct answer.
In an online course you take the instructor’s part of explaining the theory or problem out, and you are just given the problems and asked to solve them yourself with just the use of the book as help. For example, I have taken an online chemistry course, and it was hard because you only had the explanations the book gave you which did not break down the theory’s complex jargon, and you had to answer 10 to 15 problems where you had no idea where to get study material to find the answer. I failed the Environmental Chemistry course, and I never took another online science class again.
An online math and science course that utilizes video lectures where the professor actually solves the problems would offer help to the student, however, there is no way you can ask immediate questions and get immediate answers unless you use video conferencing, however, you have to then allow for students who have dial-up internet service. Also, some students may not be able to get access to purchasing the video conferencing software, and the course would then have to be done in real-time with everyone online at the same time which would make the server really busy. That is why the face-to face interaction is so important because you do not have to wait for an e-mail, or everyone having problems logging on at the same time.
Taking an online math or science course is solely up to the student, and it is a choice you should not take lightly because if you think it is easier online it is not in my experience, and in my opinion. A face-to-face, classroom lecture in these types of high level math and science courses is needed, not the safe, convenient, and quick online approach with only the use of your computer and a textbook.
