VII.  Methods of Instruction

This is a hands-on course involving lecture, demonstration, and lab work. Criminal video evidence will be examined using the video analyst and ComPARAprint/SAFIS software. The course may include guest speakers from law enforcement agencies and an optional tour of a forensic/video department. Supplementary materials may include videotapes, lab and criminal investigation kits, electro-optical aids, and forensic light sources.
Course may be taught as face-to-face, media-based, hybrid or online course.

VIII. Course Practices Required

Students will be expected to prepare for class by reading product manuals/inserts and supplied readings. Assignments will include analysis of videotapes, FACES drawings, ten print inked cards, and direct examination of actual evidence. Students will participate in a critique of these assignments to develop analytical and deductive skills. Students will learn to produce detailed written correspondence, logs, and reports, as well as to effectively report findings orally.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.
