CBESS (Computer-Based Educational Software System) is a set of 22 programs addressing authoring, instructional delivery, and instructional management. The programs are divided into five groups: (1) Computer-Based Memorization System (CBMS), which helps students acquire and maintain declarative (factual) knowledge (11 programs); (2) Language Skills Computer Aided Instruction (LSCAI), which helps students learn new vocabulary by presenting exercises of four to nine words (2 programs); (3) the Equipment Problem Solving Trainer (EPST), which permits authors without programming skills to create simulations of equipment (4 programs); (4) Script-Based Computer Assisted Instruction (SBCAI), which presents script-based instruction that creates "ad hoc" computer assisted instruction (3 programs); and (5) Instructional Management (2 programs). The two management programs are "Cop," which presents a linear sequence of lessons to a set of students, and "Course," which specifies the sequence of lessons, the mastery criteria, and student rosters. CBESS databases may be developed and delivered in both the MS-DOS and Berkeley UNIX environments. In addition, all CBESS programs except EPST may be run on the Novell network in protected mode.
