UFO和声称的绑架事件调查(三)——被外星人劫持者和访问外星球的人

在未受良好教育的人面前,类似UFO故事的墨迹很难干去。从前有个传播者叫乔治·亚当姆斯基(George Adamski,1891-1965),与一个英国作家戴斯蒙德·雷司列(Desmond Leslie)合著,出版了一本书,书名叫《飞碟登陆》(英国图书中心,1952)。按照亚当姆斯基的说法,他从事飞碟业是因为在宗教领域没有赚到钱,亚当姆斯基来到美国,兜售他的书,并到处讲他去金星、火星和土星旅行的情景。我们听过他在肯塔基路易斯威尔的演讲,在这次演讲中,他说了一些在金星表面上行走的情形。在提问过程中,我们问他的脚是否已经好了。“你这是什么意思?”他问。“因为金…     

Evaluation of a Web-based introductory psychology course: I. Learning and satisfaction in on-line versus lecture courses

We offered introductory psychology on the World-Wide Web (WWW) and evaluated the on-line format relative to the traditional lecture-test format, using a pretest-posttest nonequivalent control group design. Multiple sections of the introductory course were offered each semester; on-line and lecture sections were taught by the same instructor, the same textbook was used, and the same in-class examinations were taken. For on-line sections, mastery quizzes, interactive individual exercises, and weekly laboratory meetings replaced lectures. Increased content knowledge was greater for the students in the Web sections, as was in-class examination performance. Use of the WWW and computers for academic purposes increased more in the on-line sections, and the on-line students showed a greater decrease in computer anxiety. The students in the on-line sections expressed appreciation for course components and the convenience of the course, but the lecture sections received higher ratings on course evaluations than did the on-line sections. Learning and course satisfaction were dissociated in the two course formats.
