This document describes the development and implementation of an open learning course for shift operators who work in British process industries. The course was developed collaboratively during 1979-82 by B.P. Chemicals Ltd. and Grimsby College of Technology and Arts, using the Business and Technician Education Council certification program. Following an abstract in German and a short introduction, the two collaborating parties are described. Open learning is described as learning for which there is often no entry requirements; learners can choose what to study, where and when to study, and what instructional materials to use; specially prepared packages of instructional materials are often used; and learners will have regular contact with a tutor and/or counselor. The training needs of B.P. Chemicals Ltd. (including the requirements that the course involve no time off work, have no academic entry requirements, be provided at no cost to students, and lead to a nationally recognized qualification) are listed, as well as the Grimsby College response to those constraints. The course is described in terms of units for three levels (mathematics, physical science, chemistry, instrumentation systems, communications studies, unit operations, fluid and heat transfer, safety, communication studies, plant technology, unit operations, plant combustion and steam, and student projects), learning objectives, materials, course organization, student recruitment for the pilot year, and dropouts among the pilot group. The next section describes the activities since the pilot year, including changes made in the course on the basis of student feedback. The document concludes with short sections on the value of the training to the company, the titles of student projects, and the costs of open learning. (CML)
