In response to a survey which showed library users to be deficient in research skills, the Technological Institute of Monterrey, Mexico, developed a programed course in library skills using the Personalized System of Instruction (PSI). The course structure featured mastery learning, self-pacing, student tutors, and emphasis on written materials. Each unit contained an introduction which attempts to motivate the student, followed by instructional objectives and materials, and evaluation. The elective course consisted of 12 units covering library resources, specialized sources in engineering and business administration, and research techniques which enable the student to investigate topics in his own field of interest.
