This book discusses recent developments in Input-Output (I/O) models for microcomputers and applications of I/O models in regional studies. It provides background information on traditional I/O models and a set of working examples of I/O applications for users.
Drawing on recent research in the Sudan, Ivory Coast, Kenya and Tanzania, the contributing authors analyze broad patterns of social and political change brought about by the rapidly increasingly use of microcomputer technology in Africa.
An introduction to microprocessors, updated to cover recent models. Designed as a first course in microcomputers, this new edition covers the hardware and machine language software of the 8080/8085 and Z-80 8-bit microprocessors. It explores various aspects of microcomputer technology using examples of 8080/8085 and Z-80 applications.
Work practices and organizational processes vary widely and evolve constantly. The technological infrastructure has to follow, allowing or even supporting these changes. Traditional approaches to software engineering reach their limits whenever the full spectrum of user requirements cannot be anticipated or the frequency of changes makes software reengineering cycles too clumsy to address all the needs of a specific field of application. Moreover, the increasing importance of ‘infrastructural’ aspects, particularly the mutual dependencies between technologies, usages, and domain competencies, calls for a differentiation of roles beyond the classical user–designer dichotomy. End user development (EUD) addresses these issues by offering lightweight, use-time support which allows users to configure, adapt, and evolve their software by themselves. EUD is understood as a set of methods, techniques, and tools that allow users of software systems who are acting as non-professional software developers to 1 create, modify, or extend a software artifact. While programming activities by non-professional actors are an essential focus, EUD also investigates related activities such as collective understanding and sense-making of use problems and solutions, the interaction among end users with regard to the introduction and diffusion of new configurations, or delegation patterns that may also partly involve professional designers.
Originally published in 1989, this book differed from others on the topic of microcomputers and education at the time, in that it focuses on the influence that microcomputer technology has on children in their early years, specially pre-school and elementary ages. Microcomputers have the capacity to do great harm as well as good and a full explanation of the technical and philosophical issues involved will be of interest to a number of disciplines. Other topics explored are – the potential uses of microcomputer-technology in early childhood education and current research and theory building on microcomputers and early education. This book should be read by teachers, sociologists, psychologists and researchers in education.
Selected as one of the outstanding instructional development books in 1989 by the Association for Educational Communications and Technology, this volume presents research in instructional design theory as it applies to microcomputer courseware. It includes recommendations -- made by a distinguished group of instructional designers -- for creating courseware to suit the interactive nature of today's technology. Principles of instructional design are offered as a solid base from which to develop more effective programs for this new method of teaching -- and learning.
