Even though I did get the excel sheet with macros to open on my machine, I never was able to get it to work like it was supposed to. I tried changing values, and nothing happened. I wonder what I’m doing wrong . . .

Well, I just tried. Excel security is checked to be prompted about macros and, in fact, I am all the time getting this message on other files I receive. With yours, I got no “macro warning” even though the option was checked at the time when I tried it.

I opened the spreadsheet again after checking the setting, and still no macro alert. I use a Mac — I hope that’s not the issue. I shouldn’t be. I’ll try it on my PC and see if there are different results.

I like your new theme — kind of like the Chem Department “Drupal” site we looked at today.

I must say that the charts and graphs looked really swell — I was just too inept to get them to work.

One thought, though, is how the revised approach uniqueness deals with the potential for information overload (being overwhelmed) as you describe it. Students still have a lot to sort through, even if it comes at them at different times. So here, I guess, is one of those "assessment" questions — whether the altered approach enabled by the "technological" adjustments results in students feeling less overwhelmed and better able to make sense of the chemical conepts. Part of your objective is to help students learn the chemistry better, but there’s also an affective component here — enabling students to react less negatively to the world they are being exposed to (esapecially those students who do not see themselves as moving toward science as a fiel).

Good luck with it!
