ELLIS products combine the technology of computer assisted instruction with established instructional theories to produce the most innovative ESL program available. ELLIS products effectively utilize the computer for language learning, giving students realistic situations and the opportunity to play an active role in the learning process. Instructors can use this Instructor Guide as a resource tool.
Many of the topics that are commonly placed in the area of recreational mathematics have occupied their niches for many years. Therefore, although the bulk of the material in this book was written almost four decades ago, it is largely still topical. The primary areas that are not are where the computer has increased our capability. At the time it was written, the four-color theorem was not yet proven and the largest known prime was but a shadow of what it is now.
In 1998 and 1999, three of the largest providers of educational tests introduced computer-based versions of proficiency tests for English as a foreign language. Around the same time, many institutions began to offer Web-based tests for particular language courses and classes. These two phenomena have greatly added to the momentum of work in computer-assisted testing and mean that assessment through computer technology is becoming a fact for language learners in educational settings and therefore for teachers and researchers.
With a highly applied and computational focus, this book combines the important underlying theory with examples from electrical engineering, computer science, physics, biology and economics. An expanded list of computer codes in an appendix and more computer-solvable exercises in the text reflect Strang’s interest in computational linear algebra. Many exercises appear in the sections and in the chapter reviews. Exercises are simple but instructive.
Charles Babbage (1791-1871) is today remembered mainly for his attempt to complete his difference and analytical engines, the principles of which anticipate the major ideas of the modern digital computer. This book describes the evolution of Babbage's work on the design and implementation of the engines by means of a detailed study of his early mathematical investigations.
