Computer Supported Learning Environment of Programming, Documentation and Presentation for Novice Programmers

基于编程、文档和演示在日常活动中密切相关的信念，本研究旨在为程序员新手提供一个计算机支持的学习环境。该环境支持有效地学习从编程到演示的技能，以及逻辑思维能力。在这项研究中，我们开发和结合了包括编程方法论、编程语言和系统以及自然语言处理应用在内的各种技术。我们的贡献概括如下：1.新手程序员的学习环境我们构建了一个支持程序设计、编码和简单文档学习的环境。通过这个学习环境，用户可以享受到对语法错误和运行时错误的调试支持。对编程的支持从编程方法论的角度来看，我们把重点放在骨架编程上，在这种编程中，程序员被鼓励用现成的组件(骨架)来构建程序。在骨架编程基础研究的基础上，构建了骨架编程系统。支持文档我们开发了一种算法来检测和纠正日语文本中可能的同音异义词错误，并将该算法作为校对工具实现，使用户能够准备高质量的文档。此外，我们设计并实现了一个统一编程语言和文档准备语言的系统，使用户能够有效地准备所需的文档。对演示文稿的支持我们开发了一个系统，可以根据给定的文本自动生成演示文稿。该系统结合了一些自然的表示技术，如关键词提取、分词成单句等。

Standing on the conviction that programming, documentation and presentation are closely related in daily activities, this research aims to propose a computer supported learning environment for novice programmers. The environment supports to learn skills from programming to presentation effectively, together with logical thinking faculties. In this research, we developed and combined various technologies including programming methodology, programming languages and systems, and applications of natural language processing. Our contributions are summarized as follows.1. Learning environment for novice programmersWe constructed an environment that supports learning of program design, coding, and simple documentation. Also we implemented another environment that runs within browsers using Java By this learning environment, users can enjoy debugging supports for both syntax errors and runtime errors.2. Support for programmingFrom the viewpoint of programming methodology, we put our focus on skeleton programming in which programmers are encouraged to build a program from ready-made components (skeletons). We con structed a system for skeleton programming on top of basic studies of skeletal programming.3. Support for documentationWe developed an algorithm to detect and correct possible homonym errors within Japanese texts and implemented this algorithm as a proofreading tool which enables users to prepare high-quality documents. In addition, we designed and implemented a system that unifies both programming and document preparation languages, which enables users to prepare desired documents effectively.4. Support for presentationWe developed a system that automatically generates presentation sheets from a given text. The system combines some natural presentation techniques such as keywords extraction, division into single sentences, and so on.
