ATECHNOLOGICALFRAMEWORK APPLIED TO ENGINEERING ACADEMIC AND RESEARCH NETWORKS
Edmundo Tovar, Nelson Piedra, Janneth Chicaiza , José Carrillo
The current state of the web technologies allow the development successful of academic collaborative networks
focused on the research. This paper proposes a framework that satisfies the work requirements of engineering academic and researchers teams located in different geographical areas. Aweb site integrates all the technologies selected. Specific tasks as the communication, contents management, or links management can be solved in collaborative way with the application of the web technologies selected. This framework can be applied in master or doctoral studies that follow ..

In Proceedings of the 2009 Euro American Conference on Telematics and information Systems: New Opportunities To increase Digital Citizenship (Prague, Czech Republic, June 03 – 05, 2009). EATIS '09.

ABSTRACT
Open Educational Practices and Resources are a direct response to privatization of knowledge; they promote their exchange across the world with the aim of increasing human intellectual capacity. In this document we will discuss the Open Educational Practices and Resources Movement and the notion that knowledge is a public good where technology in general, and specifically Web 2.0, provide an extraordinary opportunity for people to acquire key competences in a knowledge society while they share, use, and re-use digital contents….

CALL FOR PAPERS – Special Issue on Multidisciplinary Applications and Future Trends of Learning Objects
Summary
One aspect of e-learning current receiving considerable attention is the Learning Object, i.e., an entity of learning capable of being reused in different instructional situations. Therefore, Learning Objects are fundamental elements of a new conceptual model for content creation and distribution. As a result, Learning Objects are one of the most significant promises in order to increase and improve the effectiveness of learning process.

STUDY OF THE APPLICATION OF NEURAL NETWORKS
IN INTERNET TRAFFIC ENGINEERING
Nelson Piedra, Janneth Chicaiza, Jorge López, Jesús García
Abstract: In this study, we showed various approachs implemented in Artificial Neural Networks for network
resources management and Internet congestion control. Through a training process, Neural Networks can
determine nonlinear relationships in a data set by associating the corresponding outputs to input patterns.
Therefore, the application of these networks to Traffic Engineering can help achieve its general objective:
“intelligent” agents or systems capable of adapting dataflow according to available resources. In this article, we
analyze the opportunity and feasibility to apply Artificial Neural Networks to a number of tasks related to Traffic
Engineering. In previous sections, we present the basics of each one of these disciplines, which are associated to
Artificial Intelligence and Computer Networks respectively.

MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem. The posterior probability distribution of trees is impossible to calculate analytically; instead, MrBayes uses a simulation technique called Markov chain Monte Carlo (or MCMC) to approximate the posterior probabilities of trees.
The program takes as input a character matrix in a NEXUS file format. The output is several files with the parameters that were sampled by the MCMC algorithm. MrBayes can summarize the information in these files for the user. The program features include:

Rubric for Effort
5 Points: Excellent
The project clearly shows that much effort went into it.
Looks complete.
All the parts work as intended.
3 Points: Great start but needs work
The project looks like parts of it were thrown together at the last minute.
Looks mostly done, just needs some touch up here and there.
Some parts do not work as intended.
1 Points: Not "shaped" yet, still rough
The project looks as if it was put together in a hurry.
Still needs quite a bit of work, just doesn't look done.
Full of errors, parts don't work as intended.

Cómo crear una rúbrica de evaluación
Un ejemplo ayudará a entender qué es y cómo funciona una rúbrica de evaluación.
Para ello utilizaremos la desarrollada por Kay Ezzell (Ezzell, 1997) para valorar presentaciones multimedia, con ligeras modificaciones.

How often have you attempted to grade your students' work only to find that the assessment criteria were vague and the performance behavior was overly subjective? Would you be able to justify the assessment or grade if you had to defend it? The Rubric is an authentic assessment tool which is particularly useful in assessing criteria which are complex and subjective.

The advantages of using rubrics in assessment are that they:
allow assessment to be more objective and consistent
focus the teacher to clarify his/her criteria in specific terms
clearly show the student how their work will be evaluated and what is expected
promote student awareness of about the criteria to use in assessing peer performance
provide useful feedback regarding the effectiveness of the instruction
provide benchmarks against which to measure and document progress

Steps in Rubric Development
Determine learning outcomes
Keep it short and simple (Include 4 – 15 items; use brief statements or phrases)
Each rubric item should focus on a different skill
Focus on how students develop and express their learning
Evaluate only measureable criteria
Ideally, the entire rubric should fit on one sheet of paper
Reevaluate the rubric (Did it work? Was it sufficiently detailed?)

Overall Use of Blogs
Blog entries are few and generally simple retellings of personal events. No comments are made on blogs of others. Almost all required blog entries and comments have been completed. Five blog entries and five comments are submitted, though not all of them may give evidence of a substantial contribution. Five blog entries and five comments are submitted, all of which are substantial. Beyond the required five, your blog includes many more reflections.

The blogging responses demonstrate an integration of concepts and principals from classroom discussions and reflect an understanding of fundamental principles surrounding the problems and myths surrounding homelessness.

Blogging Rubric
I found this rubric on Education World for grading blog posts. I thought it was an interesting way to hold students accountable for what they are posting. Grading or at least having standards for each blog post would be my concern. You may have students that write a lot and then students who do not write enough. Having a rubric would help all students identify your expectations as a teacher as well as making sure their comments are appropriate. Obviously this rubric will need to be changed to fit your specific assignment, but is a great jumping off point.
