Who contributes voluntarily to OSS? An investigation among German IT employees

Based on newly assembled survey data, we analyze which individual characteristics of IT employees are associated with the willingness to participate voluntarily in Open Source Software (OSS) projects. We find that, contrary to common expectations, formal educational attainment is not positively associated with the probability or level of OSS contributions. The group of university dropouts, however, does show a particularly high probability of working on such projects. Furthermore, we obtain the striking and novel finding that work-related OSS activities play an important role in determining voluntary OSS contributions during leisure time. Although one has to be cautious regarding the direction of causality, we interpret this as evidence of career-oriented motives in voluntary OSS contributors. The finding is also reinforced by our more specific analysis of the importance of such motives in determining the actual effort invested in OSS projects.     

Consumer learning for university students: a case for a curriculum

This article indicates how the application of a simplified version of the analytical abstraction method (AAM) was used in curriculum development for consumer learning at one higher education institution in South Africa. We used a case study design and qualitative research methodology to generate data through semi‐structured interviews with eight learning facilitators at the Cape Peninsula University of Technology. This data set forms the basis of the reported research. Application of basic‐ and higher‐level analysis resulted in the identification of patterns that confirmed the need for consumer learning and informed the situation analysis with regard to a ‘readiness climate’ at the institution. We also gained insight into aspects that need to be considered during curriculum development for consumer learning as the AAM has proved to be a useful guiding tool in developing a structured explanatory framework for curriculum development. The article concludes with the view that the promotion of consumer learning in university curricula has been under‐researched and that, despite current efforts, university curricula are slow to adopt consumer learning as a critical learning outcome. We suggest several possibilities that might assist in overcoming this inertia.     

PLATO: An Automatic Teaching Device

PLATO?a teaching machine developed during the past nine months at the Coordinated Science Laboratory of the University of Illinois?is a device for teaching a number of students individually by means of a single, central, high-speed general-purpose digital computer. Each student is provided with his own keyset and television display. The keyset enables the student to control the sequence of materials presented to him by the machine, as well as to transmit to the computer answers to its questions. The computer communicates to each student by closed circuit television. It selects slides and writes or erases sentences and diagrams on a storage tube. These two outputs are superimposed and displayed on the student's television screen. Not only are textual materials presented to each student at a rate determined by that student, but the computer frequently poses questions. The student's answers?which may take the form of numerals, algebraic expressions, or words and phrases ?are judged by the computer without revealing the correct answer to the question. Supplementary material is presented by the machine upon request for any question which the student finds difficult. The computer keeps detailed records of each student's progress through the material. Though a two-student version of PLATO is now in operation, the paper describes in detail an earlier one-student system. The system has been used to present a variety of subject matters, ranging from mathematics to topics in French grammar.
