A Computer-Assisted-Self-Evaluation (CASE) program in oncology is described. The program is based on motivation by immediate, informative feedback, and involves the computer-guided interaction of a student with a series of microfiche cards. The computer leads the student through a series of 16 questions and associated explanations and recommendations based on the answer choices. Since all textual materials are placed on microfiche cards, the computer is only required to print simple, prearranged sentences and comments. As a result four students, using different CASE topics, can time-share the same computer terminal. This time-sharing capability, together with the large but compact, low cost information storage afforded by the use of microfiche, makes the cost of this system comparable to that of conventional study aids. The use of the CASE system as an educational aid and self-tutoring mechanism has been well accepted by faculty and students.
本文介绍了一种肿瘤学计算机辅助自我评估（CASE）程序。该程序基于即时、信息丰富的反馈来激发学生的积极性，它涉及学生与一系列缩微胶片卡片在计算机引导下的互动。计算机引导学生回答一系列16个问题，并根据答案选项给出相关解释和建议。由于所有文本材料都放在缩微胶片卡片上，计算机只需要打印简单的、预先安排好的句子和评论。因此，四名使用不同CASE主题的学生可以分时使用同一台计算机终端。这种分时功能，再加上使用缩微胶片提供的大容量但紧凑、低成本的信息存储，使得该系统的成本与传统学习辅助工具相当。CASE系统作为一种教育辅助工具和自我辅导机制，已得到教师和学生的广泛认可。
