Alfred Bork 《Computers & Education》1984,8(1):1-4
It is a pleasure to return to England to give this keynote address. During my stay as advisor to the National Development Programme in Computer Assisted Learning, I attended an early CAL meeting at Oxford; I met many of you and learned about ongoing projects. This trip renews many old acquaintances. Perhaps I haven't been in England frequently enough since then. The gentleman at Passport Control at Gatwick commented. “You have been neglecting us—you haven't been here since 1980”. I will try to do better in the future!This paper has four components. I begin with a series of assertions about computers in education, some supported later in the paper. I then review two examples of computers in education developed at the Educational Technology Center. A brief interlude considers the major advantages of the computer in learning. Finally I speculate on the future of the computer in education, arguing that it will be eventually the dominant delivery device for all areas of education. I consider aspects of what will happen. 相似文献

Louis Delatte 《Language Resources and Evaluation》1968,2(3):117-120
As an addition to the report by McDonough in CHum,II (1967), 37–40, Delatte lists the operations of the Laboratoire d'Analyse statistique des Langues Anciennes at Liège. He
describes eight programs for automatic processing, automatic composition and printing of concordances, and various statistical
operations. Forty-three Latin works and five Greek, totaling approximately 600,000 words, are catalogued. 相似文献
