The major objective of the study was to provide an overview of current practices and problems in training Vietnamese Air Force personnel in a variety of technical specialties. Observation of VNAF classes and interviews with VNAF students and their USAF instructors were conducted at four CONUS Air Training Command technical training centers. It was found that demonstration-performance instruction coupled with 'hands-on' practice training aids were most effective with VNAF STUDENTS. Willingness to ask and respond to questions in class was dependent upon how well the students knew their instructor and their facility with the English language. English comprehension, especially in understanding technical terms, was found to be a significant and widespread problem. (Author).
