Learning Objects for eLearning Systems

Although LO management is an interesting subject to study due to the current interoperability potential, it is not promoted very much because a number of issues remain to be resolved. LOs need to be designed to achieve educational goals, and the metadata schema must have the kind of information to make them reusable in other contexts. This paper promotes the design, implementation and evaluation of learning objects in the field of university education, with a specific focus on the development of a metadata Typology and quality evaluate tool.

Learning objects quality management for e-learning systems

Although LO management is an interesting subject to study due to the current interoperability potential, it is not promoted very much because a number of issues remain to be resolved. LOs need to be designed to achieve educational goals and the metadata schema must have the kind of information to make them reusable in other contexts. This paper promotes the design, implementation and evaluation of learning objects in the field of university education, with a specific focus on the development of a metadata typology quality evaluate tool and a methodology to promote LOs of quality supported by multi-agent architecture.

Creation and assessment of learning objects for the definition and geometric representation of operations and applications of vectors

Often, when learning mathematics, certain concepts are not well understood, problem-solving processes and meaningless exercises are memorized, which consequently are easily forgotten. Trying to overcome this problem, this project presents a methodological approach to promote learning through motivation, use of Geometrical Representations (GR), and knowledge transfer. This is about a collection of six Learning Objects (LO) that have been designed to support teaching and learning strategies for defining vector operations and its applications. The proposal was created under the guidance model ADDIE (Analysis, Design, Development, Implementation and Evaluation). During the stages of analysis and design, instructional strategies were planned, and they were believed to help the generation and testing of mental models that represent the topics discussed. In the development stage, each of the resources and activities was built, and then packaged and labeled through eXelearning. To ensure as far as possible quality and detect any errors or ambiguities in LO we evaluated (from a pedagogical and technical) using an adaptation of the HEODAR (Herramienta de Evaluación de Objetos Didácticos de Aprendizaje Reutilizables) - Tool for the Evaluation of Educational Reusable Learning Objects -. The results obtained showed that the teaching proposal is of good quality. Through this assessment, aspects were detected and reviewed to improve the quality of LO. Among them we can highlight the creation of the application e-vector for the distribution of the teaching proposal through mobile devices, and a website that stores and distributes the six LO through internet.

Promoting quality during learning-object management through experts and users

Like any digital resource, learning objects are managed in different stages: design, creation, delivery and evaluation. However, it is not very clear how their quality can be strengthened to obtain optimum functionality. This means that there is no clear definition as to the stages in which learning objects need to be evaluated and neither are there any specific models that can help in the design of learning objects to meet different kinds of targets and tools for their evaluation. This paper presents a proposal for learning objects design and evaluation during their management in the four stages proposed by the context, input, process, and product (CIPP) model.

Psychometric testing for HEODAR tool

A large number of educational resources are stored on the Internet, several of which are of poor quality, because they could be not assessment with an appropriate instrument or another strategy. An instrument is considered adequate, among others criteria, when it is submitted a psychometric test, which allows assessing its validity and reliability. This research presents the results of the analysis for an Evaluation Tool of Reusable Learning Objects (Herramienta de Evaluación de Objetos Didácticos de Aprendizaje Reutilizables, HEODAR). The tests show an elevated reliability in the elements of each category of the questionnaire. The results of the factor analysis indicate that there is sufficient evidence to opt for a one-dimensional factor solution type for the scales. Items with low weights are not relevant, so they could be excluded, restructured or integrated into a new factor.

Applying CIPP Model for Learning-Object Management

Although knowledge management process needs to receive some evaluation in order to determine their suitable functionality. There is not a clear definition about the stages where LOs need to be evaluated and the specific metrics to continuously promote their quality. This paper presents a proposal for LOs evaluation during their management for e-learning systems. To achieve this, we suggest specific steps for LOs design, implementation and evaluation into the four stages proposed by CIPP model (Context, Input, Process, Product).

Supporting the Quality of Learning Objects Through Their Ranking Visualization

The quality of Learning Objects (LOs) is currently being promoted by certain tools which consider specific criteria for their evaluation; however, there is no existing methodology that considers both the value assigned to the LO itself and the percentage related to the number of evaluators who have compared the quality of resources. As in the case of various products offered through the Internet backed by an assessment of users in a unified ranking, the purpose of this paper is to suggest a proposal for the automated assessments of experts who can clearly see the best or worst aspects in LO quality.
