Chem21Labs: There are prelab and postlab assignments for each experiment. You will be enrolled within 24 hours of your scheduled lab day if you attend the check-in lab. Please send Dr. Pasternack an e-mail if you experience problems with the program after that time. Advantages of Chem21labs 1)You get immediate feedback on your calculations – as soon as you do them. a.The computer will give you three tries to get the answer but if you are still unable to get it correct, it will provide you with the correct answer so you can continue with the analysis. Although there is a small point deduction per try, students do better because they don’t unknowingly make the same error repeatedly when they don’t understand something. b.There are hints provided for the 2ndand 3rdtries. c.There are sample problems on Blackboard that you can do prior to the assignments. They are not graded. They include feedback for how to do the calculations correctly. 2)The pre-lab assignments have resulted in a greater level of preparedness for the experiment as shown by fewer students who neglect to do important parts of the experiment and by students generally finishing the lab more quickly. 3)The assignments are nearly paperless. All assignments are submitted electronically, although you will still need to turn in printed graphs for some of the experiments. 4)You will be able to work on your assignments from any location with internet access. The lab write up from the manual and reference information are available from within the program. 5)If you experience computer problems with your personal computer, any work you have done will not be lost. Chem21Labs saves your work on their servers every time you make an entry.
