面向计算机系统教学的在线学习环境构建与教学方法研究

The courses about the computer system are important for the undergraduate students major in computer science. Due to the complexity of computer system, these courses are also difficult for students to understand and grasp. The purpose of this project is, the first, to establish the computer system oriented online learning environment, including the online lab system for the hardware labs. The students can use it as a platform to learn the courses, to communicate and also to do the labs. The second purpose is to analysis the big data of the students learning activities and their lab codes, try to discover the student’s cognitive process and evaluate the teaching perform, so to implement the whole process of object based education (OBE). The difficult and key points of the project are the construction of computer system lab oriented online learning and lab system, and the analysis of learning activities based on the big data, such as lab codes. The goal of the projects are to finish the construction the computer system lab oriented online learning and lab system, and use it to improve the traditional pedagogics and labs to improve the teaching performs of relative courses. At least 3 papers will be published when the project is finished.

计算机系统课程是计算机专业本科生的核心课程,由于计算机系统的复杂性,学生学习掌握的难度很大.本项目研究面向计算机系统课程的在线学习环境,以在线实验环境建设为基础,建立学生学习、交流、实验的平台，并通过对其学习行为及实验代码迭代的过程分析，对教学效果进行评价和反馈，实现基于学习成效教学（OBE）的全过程。在此基础上，进一步揭示学生学习过程中的认知过程和规律，提高计算机系统课程的教学效果。项目研究的重点和难点在于面向硬件系统实验的在线学习/实验环境的建设，以及基于实验代码迭代的学习行为分析。项目预期目标是完成一套能支撑计算机系统课程教学的在线教学和实验环境，尝试改进传统的教学和实验方法，发表高水平论文3篇。

信息社会时代下，计算机人才的培养质量是衡量一个国家科技竞争力的重要指标。教学实验，尤其是面向计算机系统实现的硬件实验，是提高计算机人才培养质量的关键。本项目研究以揭示硬件系统教学实验对学习者的学习成效影响为目标，通过研制交互式学习环境提升学习者实验体验，并采集学习者相关实验数据进行分析，以期发现学习者认知的变化历程，据此，提出了基于学习者个人学习特点的敏捷教学方法，以提高课程教学效果。研制的交互学习环境平台实现了基于FPGA和SOC芯片的硬件系统实验远程化网络交互实验方式，并可自动进行实验行为数据的采集和分析，有效支撑了计算机组成原理课程敏捷教学方法的改革，在清华大学计算机系的教学实践中取得了很好的效果，学生在可持续竞争力等指标上有明显的提升。项目研究取得了丰富的成果，并可为今后数字教育发展提供一个可行的思路。
