VTLOGANL: A Computer Program for Coding and Analyzing Data Gathered on Video Tape.
Hecht, Jeffrey B.; And Others
To code and analyze research data on videotape, a methodology is needed that allows the researcher to code directly and then analyze the observed degree of intensity of the observed events. The establishment of such a methodology is the next logical step in the development of the use of video recorded data in research. The Technological Innovations in Educational Research (TIER) laboratory has been researching the direct analysis of video records and is developing the VTLOGANL (Video Tape Logging and Analysis) methodology that focuses on the video record as the basic unit of analysis. The first two stages of development have resulted in methods to capture and analyze pulsed and duration events; the third stage will add intensity event coding to the system, as well as the use of a programming language that will provide an interface to the Windows operating system. Technical specifications and program features are described. In addition to providing pulsed and duration coding, VTLOGANL will move video methodologies forward as it incorporates the concepts of intensity coding and fuzzy logic analysis in the stage-three design effort. Four figures illustrate the discussion. (Contains 46 references.) (SLD)
