Design of a video tutorial for the improvement of the learning of difficult concepts and procedures in the Area of Analytical Chemistry

The study presented here examines the incorporation of a video tutorial as a supplement to learning in an advanced Instrumental Analytical Chemistry course. The video tutorial was based on "matrix effect" problem and it was designed by the instructor using audio narration from Powerpoint in the "screencast" mode. It was uploaded to the courses Web site portal (Blackboard Learn) at the University of Almeria. The video has been shown to serve as a suitable learning that prepares students for laboratory more effectively, with an average of 70% more students answering questions correctly after watching the video than after receiving only teaching assistant instruction.
