Resource Thoughts

This week I explored virtual chem. Lab programs on the internet, focusing specifically on this website http://chemlab.byu.edu/tour/Chemistry
I like how this software combines visualization of lab technique with the creation of data values so that students can combine a scientific technique with the formulas they learn about in class. While I am still a strong believer in the benefits of traditional experiments, this is a great alternative for distance education students who are unable to carry out traditional labs, for expensive labs that are no longer feasible in school, and as a pre-lab activity to help familiarize the students with what they will be doing in the lab and for what sort of data points to expect.
In my searching I have not come across any programs that combine virtual labs with simulations allowing students to visualize what is happening at the sub-microscopic level. In a titration for example, the virtual lab software allows the student to understand the technique involved (to a degree) and to generate very accurate data about pH or concentration, but it doesn’t allow them to actually see what is happening at the molecular level. Programs such as NetLogo do a much better job of helping students visualize this.
Unfortunately, as this is not free software, I was not able to generate much discussion about it with my peers. In exploring the posting this week I have encountered many new types of simulations for use in the math and science classroom that aid in visualization from the macroscopic to the microscopic level. I am amazed and impressed by the amount of free software available for use in classrooms!
