Video capable cellular phones have become increasingly important in documenting everyday life events. This trend presents educators with an exciting opportunity to extend this capability into the introductory laboratory. Having already shown the feasibility of having students create technique videos with previously owned hand-held devices, the authors focused on gains in student technique following completion of the video assignment. Short-term gains of student technique using (1) an analytical balance and (2) a Mohr pipet have been previously reported. Long-term retentions was determined and compared to previously collected short-term retention findings. An experimental group created a pipet video while a control group created a balance video. Gains in students' ability to record volumes using the correct significant figures or minimize error when using an analytical balance were compared to pre-activity and at the end of the term. This talk will discuss the results of the Pre- /Post- analysis and outline future directions for the project.
