The BASIC Instructional Program (BIP) was developed to investigate tutorial modes of interaction in computer-assisted instruction (CAI). BIP is a problem-solving laboratory that helps students while they are solving introductory programming problems in the BASIC language. The problems are presented in an individualized sequence based on a representation of the structure of the curriculum and a model of the student's state of knowledge. This paper describes the BIP system, with emphasis on recently developed features. The goal of the tutorial laboratory is informative interaction with the student, which is provided by an instructional BASIC interpreter, information on BASIC syntax cross-referenced with the BIP student manual, and debugging aids. The system also has access through the curriculum representation to features that the student may use to help her solve her current problem. These features include hints, easier "subtasks," a stored solution that can itself be executed, and an interactive flow chart representation of the solution. The nature of the student-BIP interaction is captured in an annotated student dialogue of a typical session.
开发了BASIC教学计划(BIP),以研究计算机辅助教学(CAI)中交互的教学模式。 BIP是一个解决问题的实验室,可以帮助学生解决BASIC语言中的入门编程问题。这些问题以课程结构的表示形式和学生的知识状态模型为基础,以个性化的顺序提出。本文介绍了BIP系统,重点介绍了最近开发的功能。教程实验室的目标是与学生进行信息交互,这由指导性的BASIC解释器提供,BIP学生手册中交叉引用的BASIC语法信息以及调试辅助工具。该系统还可以通过课程表述访问学生可以用来帮助她解决当前问题的功能。这些功能包括提示,更轻松的“子任务”,本身可以执行的存储解决方案以及该解决方案的交互式流程图表示。在典型会话的带注释的学生对话中捕获了学生与BIP交互的本质。 P>
