Making It All Compute: Busting Cultural Barriers from Egypt to the United States

Lamia Youseff, a project manager at Google, was a few years into her graduate program in computer science at the University of California, Santa Barbara (UCSB), when she suddenly noticed that she was the only female student in her advanced operating systems class. She was somewhat baffled. Her undergraduate class in computer science at The American University in Cairo had been 50% men and 50% women, and it was common for a female student to be at the top of the class. "I never realized that computer science as a field is a male-dominated field until I moved to the U.S.," she says. "Luckily," she adds, "I was the top student in that class as well."

GENDER DISPARITY IN ICT COMPETENCY AMONG TEACHERS IN FEDERAL TERRITORY LABUAN, MALAYSIA.

ICT has today become a must-have tool in school. For this, government has spent a lot of resources to upgrade the ICT infrastructure both in primary and secondary schools. A lot of money has been spent to train teachers as well. With this investment, the government hopes that ICT can be fully utilized. However, ICT facilities can only be fully used if teachers are competent. This study was to assess the level of ICT competency among teachers in Federal Territory Labuan. In particular, it examined the differences between females and males in terms of nine components (MS WORD, MS POWER POINT, MS EXCEL, MS ACCESS, WWW, E-MAIL, OPERATING SYSTEM, MULTIMEDIA, and VIRTUAL CLASS application) related to ICT. A total of 256 teachers participated in this study. The results of the study showed that there is a small gap between females and males teachers. In some application such as MS WORD, MS POWER POINT, MS EXCEL, female teachers were more competent compared to male teachers. In contrast, male teachers are more capable in MS ACCESS,WWW, E-MAIL, OPERATING SYSTEM, MULTIMEDIA, and VIRTUAL CLASS application. Various reasons attribute to these results.

Web based peer assessment: attitude and achievement

The specific features of the Web-based peer assessment are to utilize Internet resources to facilitate contacts between individuals and information, to assist in brainstorming among individuals, and to generate more meaningful learning at the higher education level. In this research, authors focus predominantly on attitudes of computer science students toward Web-based peer assessment using NetPeas as the interactive channel and management center. NetPeas is a Web-based peer assessment system implemented for two-way anonymous peer assessment. In an evaluation held in spring 1999, this study recruited a sample of fifty-eight computer science undergraduate students enrolled in an operating systems class in a research university of Taiwan. Attitudes toward Web-based peer assessment were measured by a post-test questionnaire, including several affective components, for example, "satisfied" or "unsatisfied" about the Web-based peer assessment. The result demonstrated that; (1) significantly more students favored this new learning strategy; and (2) students with positive attitude outperformed those with negative attitude. No matter positive attitude toward Web-based peer assessment brings about higher achievement or higher achievement promotes positive attitude, teachers must take care of students' subjective feelings in enhancing effective Web-based peer assessment.

Web-based peer review: the learner as both adapter and reviewer

This study describes an effective web-based learning strategy, peer review, used by 143 computer science undergraduate students in an operating systems class at a Taiwanese university. Peer review, based on social constructivism, can be easily implemented via the authors' well-developed web-based peer review (WPR) system. Through peer review, the authors hope to form an authentic learning environment similar to an academic society in which a researcher submits a paper to a journal and receives reviews from society members before publication. Students using this learning strategy are expected to develop higher level thinking skills. The WPR system functioned in the following roles in this study: (1) an information distribution channel and management center for assignment submissions and peer review; (2) a forum for peer interaction and knowledge construction; and (3) storage for knowledge construction procedures. An evaluation of learning effects and students' perceptions about peer review during the spring of 1998 revealed that students not only performed better under peer review, but also displayed higher level thinking skills, i.e., critical thinking, planning, monitoring, and regulation. Students perceived peer review as an effective strategy that promoted their learning motivation. However, merely being an effective reviewer or an effective author may not excel in a peer review environment. The most effective individual appears to be the strategic adapter who effectively constructs a project, adjusts to peers' comments, and serves as a critical reviewer as well.

Teaching experimental design in an operating systems class

This paper describes an operating systems (OS) class that departs from more common approaches by introducing experimental design explicitly as part of the course material. Instead of implementing operating systems components or modifying existing operating systems, students conduct a series of experiments that measure the performance of system services and try to infer information about their implementation from the results. These experiments reinforce the OS concepts presented in lecture, and also develop a set of skills that students need for a wide range of activities: formulating and testing hypotheses, analyzing and presenting data, and writing.

Introducing empirical investigation in undergraduate operating systems

The undergraduate operating systems course can provide students with a valuable introduction to empirical testing and experimentation. This paper announces the availability of a process scheduling simulator designed to develop student empirical skills while they are learning part of the standard operating systems curriculum. The simulator is written in Java and available for direct experimentation via the World Wide Web. By accessing the remote URL through an appletviewer, students can permanently save input test data and simulator results generated in HTML format. Students are asked to test specified hypotheses about process scheduling and to develop their own hypotheses about the influence of different parameters on behavior. In order to devise experiments that make sense, students must understand how factors such as burst time and variability influence behavior. Interested faculty are invited to try the simulator and support materials in their operating systems classes.

A display and analysis tool for process-resource graphs

This paper describes the design and implementation of a graphical tool called Prograph which enables users to model and analyze operating systems process-resource graphs. The Prograph program enables users to model operating system Process-Resource graphs rapidly, analyze the graphs, and then view the different stages of the deadlock analysis. The deadlock representation and analysis tool Prograph was prototypically evaluated by the students in the graduate level Operating Systems class as well as a number of graduate students at the Computer Science Department of Oklahoma State University. The feedback obtained from the users of the Prograph program indicated that it was functional and useful for modeling and analyzing Process-Resource graphs.

O.S. bridge between academia and reality

This paper presents a different approach to solving the dilemma of balancing the theory and the practice in an undergraduate operating systems course. We are in the process of implementing a laboratory that allows students to experiment with a copy of the 386BSD Unix System. Students are guided through exercises with increasing complexity, from a single exercise of initializing a new file system to more complicated team projects. The laboratory does not require a set of machines dedicated to the Operating Systems Class which is the reason many instructors choose to use simulators or small academic operating systems. This is accomplished through the use of recent removable disk technology that provides enough speed and capacity to load the source code of a real system. This approach provides a more in-depth study of a system students are more likely to encounter when they leave school. It also allows students to work in teams in an environment closer to the real world and provides a strong foundation for students wishing to enter graduate school with intentions to specialize in the area of operating systems development.

More Experience with MINIX in an Operating Systems Lab

In operating systems classes students study the theory, concepts, and mechanisms of operating systems: system calls, layered design, the client‐server model, processes, interprocess communication, CPU scheduling, deadlock, input and output, device drivers, memory management, file systems, protection, etc. Their understanding of these concepts will be enhanced if they are given the opportunity to examine the internal operation and source code of an actual operating system and see how the various concepts and features studied are implemented. By modifying the source code to change the behavior of the operating system or introduce new features, students can further enhance their understanding and gain valuable practical experience. This article describes the use of the Apple Macintosh version of MINIX, a UNIX look‐alike operating system available in source form, in an operating systems workshop course. The use of the Macintosh version is compared to the IBM PC version. What the students learned from the work...

Experience with the language SR in an undergraduate operating systems course

In undergraduate operating systems classes, students learn about concurrent process synchronization, including such things as shared data, race conditions, critical sections, mutual exclusion, semaphores, monitors, and the test-and-set hardware instruction. They also study interprocess communication, message passing, rendezvous, and remote procedure calls. Solutions to classical problems, such as the dining philosophers, producers and consumers, bounded buffers, and readers and writers, are presented using the above concepts. However, students need to write programs in a language that provides facilities for concurrent programming in order to appreciate fully the above concepts. This paper describes the SR language and discusses its successful use as an environment for concurrent programming in an undergraduate operating systems class.

The author has used such methods in Computers and Society classes and to a limited degree in Compiler Design, Computer Architecture and Operating Systems classes and believes that such techniques have a place in the computer science classroom. It is the aim of this paper to provide an overview of participatory teaching methods and their use in computer science education.

A modified Chief Programmer Team approach to an operating systems class project

This paper describes the use of the Chief Programmer Team method in an operating systems class to implement a subset of a multiprogramming operating system. The operating system consisted of elements of Job Management, Task Management, and Data Management functions. The students were divided into four groups. One of these, called the Steering Committee, was responsible for assigning coding and design duties to each of the three coding groups. When each major part of the operating system was completed, the Steering Committee would examine the code and approve it, or return it to the coding group for revision. Thus, the Steering Committee acted as Chief Programmer to the other three groups. When all parts of the system were completed, they were linked together and tested. A comprehensive survey containing questions regarding the effectiveness of the Chief Programmer approach was given to all students. The results of this survey indicated that the group programming effort was superior to the conventional method of assigning the project, in its entirety, to each student. Key Words: Chief Programmer Team, Monitor, Operating Systems, Systems Programming.
