Computer Network Design
In this paper we discussed about challenges that are faced in teaching computer network design using problem based learning as an effective tool. Here we discussed, where it has been introduced first and the techniques that are used in teaching computer network design. A two threaded approach is used make it more user friendly. Also several modules has been introduced to decrease the distance between industry and class room.
Introduction: M.Sc degree in networks and data telecommunications is first started by University of Salford, Salford, Greater Manchester, UK in October 1990.This course has a recruitment grew of 20 students annually in its early launch and has gradually increased with high intake of 43 full time students during 1999-2000 academic year. This course is introduced mainly because the usage of modern computer networking technology is using most business organizations. Even personal computer and Internet usage also increased.
Network Architecture and Design:
A two threaded approach is used for effective teaching of this subject. The two threads that are involved are Lecture thread and PBL thread. In lecture thread we have theoretical understanding of network operation and performance ,various topics that are involved in lecture thread are network design principles, LAN design, Multi-site networks, connection to the internet, Managing ,protecting, sizing and understanding of network applications. The lecture thread comprised of 20hours of lectures and 4 hours of tutorials .The total thread is assessed to written examination of 80%.The other thread is PBL(prob0lem based l...

...ssions. Each block has a fixed number of tokens, it writes cache block when processor has block token. When we compare different protocols, token protocol is effective than other two protocols. Parallelized model is programmed with certain basic functions.
From the work gone through this paper token protocols gives better performance than directory protocols. With our investigation we can say that multithreaded versions of network faces problems with workloads and causes low exploitation in instruction level parallelism.

- Problem-Based Learning Problem-based learning is a student centered approach to learning (Evans, 2006). This learning style is trying to get the student to apply knowledge to a situation in which is new to them (Learning-Theories, 2013). The teacher takes more of a facilitator approach, this is to basically guide the student and help the student stay on track and to suggest resources that the students may use to help them through the problem-solving (Evans, 2006). To simplify this approach is to help students learn through experiencing the problem and solving the problem.... [tags: excavation, settlement, quality]

- What is PBL Problem based learning is any learning environment in which the problem that is asked is what drives the learning. In other words, to answer the problem that is given to you, you will need to look things up and learn some things before being able to answer the question correctly. The problem is given so that the students discover that they need to learn some new knowledge before they can solve the problem. The first use of PBL was in medical schools, which test the knowledge base of graduates.... [tags: essays research papers]

- Problem Solving and Goal-Driven Learning There is a growing body of research into how a learner’s (human or machine) goals can greatly influence the learning process. Study has taken place in fields such as cognitive science, psychology, education and, of most interest to us, artificial intelligence. Prior to the interest in goal-driven learning, most studies in this field focused on providing estimated functions based on limited inputs and outputs, without concern for the learning goal. The underlying principal of the goal-based methodology is that learning is, for the most part, a strategic and active attempt on the part of the learner to identify and solve a particular problem or set of...

- Collaborative and cooperative learning promotes student learning through group-oriented activities. Collaborative learning is a method of teaching and learning in which student teams will work together to create a meaningful multimedia project. Cooperative learning, which will be the primary focus of this paper, is a specific kind of collaborative learning. In cooperative learning, students work together in small groups on a structured activity. Cooperative groups will work face-to-face and will learn to work as a team.... [tags: Collaborative Learning]

- Our schools are full of a variety of children who are diverse in their own ways. What comes to mind when you hear the word diversity within schools. Many people think of race or culture, but diversity in our schools is more than that. Diversity can include race, religion, culture, and even learning styles in a classroom. In the past classrooms where not that diverse consisting of white protestant students. Currently diversity in classrooms is on the rise big time. Today’s classrooms are more effective in diversity, learning styles, and influences than past years.... [tags: Education Schools]

- Inquiry is an interactive way of learning. Students are actively engaged in their studies. Inquiry involves student-centered activities focusing on questioning, exploring, and posing explanations. The goal of inquiry is to introduce a new way of learning where students can learn about the world around them through active engagement in real-life examples. Inquiry based learning can be incorporated into all academic subjects throughout the curriculum. Science could possibly be the most effective subject to incorporate inquiry....

- Freshman learning communities (FLC) are programs where 15 to 30 first-year students register for several general-education courses that focus on a common theme (Jaffee, 2004). Although there are several different types of learning communities, they all are designed for the same purposes. One of the main purposes in implementing freshman learning communities is to assist the students in their transition to a new environment. This acclimation involves becoming better acquainted with the other students, faculty members, campus culture, and academic expectations.... [tags: higher Education, higher learning]

- E-Learning Tools This paper will discuss three tools used at the University of Phoenix that give their students transfer lifelong skills that can be used in the work place as well as everyday life. Learning Teams, rEsource, and Problem Based Learning are the tools that teach students problem-solving techniques and social skills. The rEsource contains valuable links to information resources that allows students to enhance their research skills. The Value of rEsource R-Esourcse is a valuable tool that allows students to access current course material such as simulations, announcements, access notes, review assignments, discuss questions, and take practice quizzes anytime anywhere during the...

- Using Problem-Solving Approaches in Vocational Education Problem Solving for Teaching and Learning Agricultural education has emphasized problem solving as a means of helping students to develop decision-making skills and teachers to alter their teaching methodology. The traditional method of problem solving for decision making reflects Dewey’s five-step model for learning, expanded to six steps by Newcomb, McCracken, and Warmbrod (Straquadine and Egelund 1992): (1) identification of the problem situation: What is happening?; (2) definition of the problem: What must be done?; (3) search for information: What do we need to know?; (4) analysis of data: What are the important considerations?...

- The Developments and Issues of E-Learning News Item: Clark, Don “The Pros and Cons of E – Learning”. P. 2007 <http://www.nwlink.com/~donclark/hrd/elearning/proscons.html> Presentation of the Issue E-Learning is trying to provide a more individualized, self-paced, self-directed learning experience (Clark). A survey by a Sociology Professor at CSU-Northridge showed that students in his virtual class performed 20% better than students in his traditional class (Clark). On the other hand, issues concerned with E-Learning includes the fact that students may not be as motivated since, another survey found out that only 66% of the students involved with E-Learning earned credit with a passing g...
