From Geiger-Counters to File Systems: Remote Hardware Access for the Operating Systems Course

Operating systems interface between hardware and the user, random numbers are useful for security and simulation, and file systems form the program access to them in a modern operating system. � Blending these items into a remotely accessed infrastructure forms the basis for supporting operating systems projects. This work describes the hardware, software, and communication infrastructure to support student projects by sharing remote hardware to acquire background radiations events with a Geiger counter, transforming those events into random numbers, and providing those numbers through a custom file system. Collectively, the hardware and software provide an inexpensive remote laboratory experience for computing students.

The students in this group make a presentation associated with the units of this course, PES are applied on them and the study is conducted by the data obtained from this scale. Frequencies and percentages and Wilcoxon test is used to analyze the data sets. It is found that there is a significant difference between the PES obtained student scores and those scores that passes through fuzzy logic mechanism. The scores of some students have decreased, those of some have increased while there is no significant change in some of them.

操作系统辅助教学平台的设计与实现

操作系统是计算机专业的一门核心专业课程，具有较强的实验性。由于概念多、涉及面广等因素，往往难以很好地理解和掌握，国内外在操作系统实践教学方面所做了大量研究。本文通过构造一个虚拟操作系统运行环境，试图为学习、设计和研究操作系统提供一个简单、易用的平台，为操作系统的教学工作打下了良好基础。 Operating system is one of the core computer science courses, with a strong experimental feature. It is often difficult to understand and grasp well because the course has many concepts and involves wide aspects of real operating system. A large number of researches have been done in practice teaching of the operating system course at home and abroad. In this paper, we construct a virtual operating system environment to provide a simple, easy to use platform for study, design and research of operating system. The platform has also laid a good foundation for operating system teaching work.

Design and development of WebUbu: An innovating web‐based instruction tool for Linux OS courses

ABSTRACTIn this paper, we introduce the analysis and the design of a new web‐based interactive software tool, called WebUbu, which has been developed to serve the undergraduate students' needs related to Linux Operating System (OS) issues. The aim of this software development was twofold: on the one hand to familiarize students with Ubuntu OS environment and, on the other hand to promote the self‐learning related to this Linux distribution, in the context of everyday OS classrooms. WbUbu software can be used only for interactive demonstration of features of Linux during lectures and to support instructors for evaluation of students' skills in the lab. For other tasks such as long term studying of Linux‐based OS's ‘physical’ Linux must be used. Our software is essentially a website that simulates Ubuntu operating system inside a web browser. Undergraduate students can easily explore both graphical user interface (GUI) and command line of Ubuntu's environment. Additionally, students can ascertain the acquired knowledge through an automated examination process and learn from their mistakes as they shown automatically by the software in real time. Educator can manage students' performances that are stored in a database system and assess the individual's cognitive progress resulting from the software contribution. However, WebUbu will give students the chance for practice and self assessment when they not involved in the University's educational process or ‘physical’ Linux is unavailable. That software intends to complement the existing teaching and learning methods concerning Operating Systems. © 2015 Wiley Periodicals, Inc.

Operating systems course in a business information systems curriculum

Operating systems are traditionally taught from computer science/computer engineering perspective. However, as more and more businesses progressively rely on the availability and scalability of their business information system infrastructures which are in most cases based on client/server architecture, the roles of servers and server operating systems are becoming critical with regard to business applications' availability. It turned out that many businesses in e-business era simply go 'out of business' due to the downtime caused by server operating system crashes. Therefore, operating systems, particularly server operating systems, should be taught in business information systems programs as well, with an emphasis on their business perspective. A framework for designing and delivering an operating system course in a business information systems BIS undergraduate program is presented.

Events-first programming in APP inventor

Events are a central concept in computer science. They are becoming more important with the prevalence of mobile and web platforms that use event-based programming. Yet, events are typically taught late in the CS curriculum -- e.g., in a web programming or operating systems course. We have introduced events to CS0 students from day one using MIT App Inventor, a blocks-based programming environment that enables students to create apps for Android devices. This paper presents the system's event-based model, along with typical coding problems and best-practice approaches for solving them. We advocate for increasing early emphasis on events in the CS curriculum.

Using Game-Based Cooperative Learning to Improve Learning Motivation: A Study of Online Game Use in an Operating Systems Course

Many researchers have studied the use of game-based learning. Game-based learning takes many forms, including virtual reality, role playing, and performing tasks. For students to learn specific course content, it is important that the selected game be suited to the course. Thus far, no studies have investigated the use of game-based cooperative learning in an operating systems course. For this study, an online game was developed to enable students to learn cooperatively. The findings indicate that students' desire to win the game motivates them to learn from online course materials before they play, which in turn can enable them to achieve better learning outcomes.

Experiences in teaching an educational user-level operating systems implementation project

The importance of a comprehensive implementation component for undergraduate Operating Systems (OS) courses cannot be understated. Students not only develop deep insight and understanding of OS fundamentals, but they also learn key software engineering skills that only a large development project, such as implementing an OS, can teach. There are clear benefits to traditional OS projects where students program or alter real (Linux) kernel source or extend educational OS implementations; however, in our experience, bootstrapping such a project is a huge undertaking that may not be accessible in many classrooms. In this paper, we describe a different approach to the OS implementation assignment: A user-level Operating System simulation based on UNIX preemptive signaling and threading constructs called ucontext. We believe that this variation of the implementation assignment provides many of the same educational benefits as traditional low-level projects without many of the expensive start-up costs. This project has been taught for a number of years at the University of Pennsylvania and was recently overhauled for the Fall 2011 semester. This paper describes the current version of the project and our experiences teaching it to a class of 54 students.

Is Minix more robust because it is microkernel?

In 2006, professor Tanenbaum released Minix3 with a new book and papers supporting that drivers running as processes in user mode made Minix, a microkernel operating system, more reliable than monolithic operating systems. We tested Minix3 in a operating system course at University of Sao Paulo University and unfortunately, we were able to deadlock the system after inserting a bug in a driver. Based on this problem, we make some considerations about performance and reliability in Minix3.
