  1. Thank you for including my T.H.E. article in your list.

    To summarize, I make two important points.

    1. Simulations (Java applets, Flash animations, etc.) do not provide a true science laboratory experience and even distort the concept of the nature of science. They are not a valid substitute for a good science lab.

    2. Because you cannot get all of the science you’d like from at-home experiments, they should be supplemented by something; I recommend prerecorded real experiments. They do not distort the nature of science.

    As more and more companies and individuals develop simulated labs, we absolutely must stand firm against using these in place of good hands-on lab experience.

  2. I’m amazed at how technology is changing teaching! What a boon for students in rural settings to be able to exposed to science experiments requiring equipment beyond the scope of their small school laboratories.

    Now, when they come up with an online microbiology simulation, I will be the first to sign up for a course. That was one of my favourite courses in my whole college career. If I had it to do all over again, I would probably be a microbiologist.

  3. @Norma Rickman:

    Why have a microbiology simulation when you can have actual microbiology material photographed in laboratories and presented to you on the Internet?

    You’ll find plenty of drawings and animations to use in understanding concepts. Simulations are just the same thing with allowing you to page through them.

    A picture of worth a thousand words. Real images are worth lots more than drawings for understanding real science rather than what some book or animator wishes you to memorize.

    Use drawings and animations and simulations for concepts. Use the real thing for science.

  4. I have always wondered if it was possible to complete labs for lab courses offered online. I now know it is

  5. Michael Learner has stated the situation quite accurately. For many people, the nature of science is elusive. The real world allows people to begin to understand it. The simulated world does not.

    By the way, virtual and simulated are NOT synonymous. See http://thejournal.com/articles/2008/05/05/science-labs-virtual-versus-simulated.aspx.

    Virtual can be real as in the Mars Rover program.

    The bottom line is about goals. For learning content, simulations may be a better option than a textbook or a video in some cases. Labs are not very good at delivering content learning efficiently, although any content you do learn through discovery is more likely to be retained.

    For learning about the nature of science and developing scientific reasoning skills, investigating the real world beats all other approaches by a huge margin. Science courses should provide this experience, which generally is not tested for in exams.

    It’s all about balance. Part of your science course must teach content. At the same time, you should be learning about science: the nature of science, scientific reasoning, the complexity and ambiguity of the work scientists do. Textbooks, demonstration, videos, and simuilations approach the former. True science labs (scientific investigations of the real world) introduce you to the latter.

  6. I currently offer an online microbiology course that utilizes home based, hands-on eScience Lab kits as well as a virtual case study lab. I am also developing Online Basic Chemistry I & II courses and others are in the pipeline.

  7. The online science lab technology has evolved to “online hands-on science labs.” It’s a great way to do lots more labs than can be done in classrooms or with lab kits.
