phrases (“each summer” “start of each semester” “oneat a time”) reflected design decisions about the pace of change of courses. By collecting similartypes of language and seeking common factors in the language a number of design domains wereidentified. Table 1 shows the design domains that were found.These design domains not only indicate the multi-faceted nature of the design architecture, theyalso show other characteristics. Examining each of the domains it appears that each domainrepresents a certain type of design decision. Parnas20, in his discussion of software modularity,indicated that a major purpose of modular design is to enclose design decisions in modules. Thedifferent types of decision for each domain were identified and shown in

system interms of system designs.1. IntroductionAttempts to use computer and computer-related technologies to enhance learning began withthe efforts of pioneers such as Atkinson and Suppers 1,2. The presence of computer technologyin education has increased dramatically since that time, and predictions are that this trend willcontinue to accelerate. Many of the new technologies are interactive, and it is now easier tocreate environments in which students can learn by doing, receive feedback, and continuouslyrefine their understanding and build new knowledge 3,4,5. The new technologies can also helppeople visualize difficult-to-understand concepts.Internet AccessibleRemote LaboratoryTraditional laboratory classes are scheduled only for a

Therefore, as a teaching tool in a computer architecture course, MIPS processor andVHDL could be used for teaching different topics.1- IntroductionThere are now two industry standard for hardware description languages: VHDL and Verilog.The complexity of ASIC and FPGA designs has caused an increase in the number of specialistdesign consultants with specific tools and an increase in libraries of macro and mega cellswritten in either VHDL or Verilog. VHDL became IEEE standard 1076 in 1987. It was updatedin 1993 and is known today as "IEEE standard 1076 1993". VHDL is

At the same time, the serial and parallel portscontinue to enjoy significant application in industrial control and embedded computer systems,in situations where low cost, low speed and single device communication is needed. Thissituation has given rise to the challenge that we not only need to continue teaching the paralleland serial port concepts, but also introduce the USB and Bluetooth interfacing andcommunication concepts in our courses.In this paper we present a survey of the teaching material (section 1), hardware considerations(section 2) and laboratory project demonstrations (section 3) that we have developed and used inour capstone course, to

strategyto the pessimistic one-step testing strategy. The other main result is the that if the fault bound,i.e., the upper bound on the possible number of faulty processors, is kept to the same number n inboth cases of precise and pessimistic testing, then the pessimistic strategy requires (n/2)+1testing links per processor whereas the precise strategy requires n testing links per processor. Aprocedure for selecting (n/2+1)*n/2 (2-way) links in an n-cube for use as testing links ispresented.1.

IntroductionEducating students to thrive in a world that depends so heavily on computers and the Internetrequires new pedagogical approaches to deal with the advances in technology and the resultingmalicious side effects that continually plague students1,2. The dangers, both seen and unseen arenot merely a concern for the security experts or technology gurus, but for all users of informationtechnology (IT). By now, most college students are aware of at least some of the dangers lurkingon the Internet. Yet

The learning outcomes of the foundation seminar, according tothe university's catalog, are as follows. 1. Students will develop writing, reading, speaking, listening, and information literacy skills necessary for collegiate-level academic work. 2. Students will develop capacities for independent academic work and become more accountable for their own learning.We realize these outcomes by asking students to read papers, find extra references, synthesizewhat they

These projects can be used in communication, computer networks, andinformation systems courses. One project addresses topics in satellite communications and theother covers data communications.IntroductionYears of experience by many educators coalesce around the widely-held belief that laboratoriesand hands-on learning are critical to understanding and long term retention of fundamentalconcepts in engineering. Taslidere, Cohen, and Reisman conclude that “undergraduate andgraduate students want more hands-on demos that link theory to real applications.”1 However,according to Corter, Nickerson, Esche, Chassapis, Im

Each group had twoto three people to execute the task.The Fast Track model was chosen as the courses project management model because the modeldemonstrates a non-linear development process to the students. The model further identities thedeliverables required for each project phase and the structure of the model indicates that alldocuments need to be stored in a central repository to provide easy access to all team members.The requirement of this centralized document repository emphasizes how important interactivecommunication and availability of documentation shared between all stakeholders is critical forthe success of

We alsolearned that certain aspects of the experience (such as double-blind review) were moredifficult, and other aspects (such as sequencing between chapters) were easier thanexpected.
