Online Grading of Calculations in General Chemistry Laboratory Write-Ups
Silva, Alexsandra; Gonzales, Robert; Brennan, Daniel P.
Journal of Educational Technology Systems, v38 n2 p155-163 2009-2010
In the past, there were frequently complaints about the grading of laboratory reports in our laboratory chemistry courses. This article discussed the implementation of an online submission of laboratory acquired data using LON-CAPA (The Learning Online Network with Computer-Assisted Personalized Approach), which is an open source management and assessment system. The students input their data and calculation results, after which the submitted values are automatically graded, with the grading criteria developed by the instructor along with the option of awarding partial credit. The Post-Lab LON-CAPA showed several advantages. An overall improvement of student laboratory participation was noted; this benefit was attributed to increased accountability since the students are also graded on the quality of their data. For instructors and teaching assistants, online submission reduces the time spent grading, offers a more accurate and consistent grading scheme and more attention can now be given to the other parts of the laboratory write-up, such as discussion and conclusion. (Contains 4 figures and 2 tables.)
