MATTER: Metadata Migration and Annotation. Tool of Teacher Education Resources

Despite ongoing research on learning repositories, share and reuse of Teacher Education (TE) resources remains scarce. One of the reasons is that TE communities use their own in-house resources and repositories in a rather isolated way, thus limiting resource exchange in different contexts. Further, current learning metadata specifications such as Dublin Core (DC) and LOM do not address the description of pedagogical characteristics of resources demanded by TE practitioners. To overcome these limitations, the Share.TEC project aims to provide a federated TE metadata repository based on the Common Metadata Model (CMM) as the shared reference metadata model. Key for the success of the Share.TEC project is the migration of existing TE metadata records to the federated repository, performing the necessary format conversions to CMM. Besides, practitioners should be able to make TE-based annotations of resources. These two functionalities are covered by the Metadata Migration and Annotation Tool of Teacher Education Resources (MATTER) that is the subject of this paper. Although MATTER is purposed for the Share.TEC project, it can be potentially used to support the federation of other learning repositories

CRATE: A Simple Model for Self-Describing Web Resources

If not for the Internet Archive’s efforts to store periodic snapshots of the web, many sites would not have any preservation prospects at all. The barrier to entry is too high for everyday web sites, which may have skilled webmasters managing them, but which lack skilled archivists to preserve them. Digital preservation is not easy. One problem is the complexity of preservation models, which have specific meta-data and structural requirements. Another problem is the time and effort it takes to properly prepare digital resources for preservation in the chosen model. In this paper, we propose a simple preservation model called a CRATE, a complex-object consisting of undifferentiated metadata and the resource byte stream. We describe the CRATE complex object and compare it with other complex-object models. Our target is the everyday, personal, departmental, or community web site where a long-term preservation strategy does not yet exist

Factors Affecting Faculty Use Of Learning Object Repositories: An Exploratory Study Of Orange Grove And Wisc-online

The purpose of this study was to identify factors that motivate or impede faculty use of learning object repositories (LORs). The unified theory of acceptance and use of technology (UTAUT) served as the theoretical framework for this study. Both quantitative and qualitative approaches were used in the study to explore two research questions relating to factors affecting faculty use of LORs. Research subjects were faculty and instructional staff users from two LORs: Orange Grove and Wisc-Online. This study was a two-phase design study. In Phase I, I conducted 13 interviews and analyzed data by a content analysis method. Phase II of the study was designed based on the results of Phase I. I collected data by a survey instrument from 38 respondents and analyzed the data by descriptive statistics and analysis of variance in Phase II. The results of the study indicated 22 factors as motivators for faculty use of LORs and 13 factors as barriers for faculty use of LORs. The study is the first to identify factors affecting faculty use of LORs from actual faculty users’ perspectives based on UTAUT. The study’s findings contribute to understanding the reasons that faculty use or do not use LORs and provide foundations for designing strategies to increase faculty use of LORs

Desenvolvimento de um learning object para o ensino-aprendizagem da língua inglesa : regra de formação do present simple

Dissertação de Mestrado em Educação, área de Especialização em Tecnologia Educativa.A presente investigação visa a concepção e validação de um protótipo de uma pequena unidade didáctica concebida como um Objecto de Aprendizagem “Learning Object” no formato digital, destinado a alunos do 7º ano de escolaridade, com Inglês nível III. Pretende-se avaliar a possibilidade de integração, nas aulas de Inglês como língua estrangeira, de Objectos de Aprendizagem como veículos de conteúdos e promotores da aprendizagem e aplicação da língua inglesa. O estudo visa também aferir a motivação dos colegas/professores para a prática de construção e de aplicação de conhecimentos e conteúdos em formato de Objectos de Aprendizagem. Tendo em conta a utilização das TIC em muitos dos cenários de ensino/aprendizagem e a fluidez com que muitos alunos as utilizam, parece-nos urgente elaborar materiais em formato digital que possam não só corresponder às expectativas dos discentes mas, também, contribuir para uma diversificação das estratégias de ensino e promover a produção de materiais apelativos, de fácil navegação e fácil aplicação em diferentes contextos de ensino/aprendizagem. Num primeiro momento o presente trabalho procura ilustrar as várias definições existentes na literatura para Objectos de Aprendizagem, caracterizá-los e mostrar os vários tipos de repositórios onde podem ser encontrados, bem como explicar todo o sistema necessário para normalizar e fazer funcionar os Objectos de Aprendizagem, preservando as suas características. Num segundo momento desenvolve-se o Objecto de Aprendizagem utilizando a ferramenta de autor Hot Potatoes, descrevendo-se toda a metodologia a adoptar e passos a seguir. Num terceiro momento procura-se aferir o impacto do Objecto de Aprendizagem junto de colegas/professores e verificar a possibilidade de integração do protótipo e de Objectos de Aprendizagem digitais no ensino do inglês como língua estrangeira.This study aims the conception and validation of a prototype of a small study unit conceived as a Learning Object and as a digital resource, designed to the 7th grade students of the third level of English. It is our intention to evaluate the possibility of integration, in classes of English as a foreign language, of Learning Objects as vehicles of contents and also as learning promoters and application of the English language. The study also aims to check the motivation of our colleagues/teachers to the practice of construction and application of cognizance and contents through digital Learning Objects. Taking into consideration the growing usage of the ICT in many teaching/learning sceneries and also the fluidness that many students use them, we believe it is urgent to develop digital materials and resources capable not only to answer the students expectations but also, to contribute to a diversification of teaching strategies and to promote the production of appellative materials/resources with easy navigation and also easy to apply in different learning/teaching contexts. The present study, in a first moment, seeks to illustrate the great number of existing definitions for Learning Objects, characterize LO’s and show the several repositories and its kinds where LO’s can de found. In this first moment we also explain all the necessary system to create standards and certain rules in order to better create, show and work with LO’s, preserving all its features. In a second moment a Learning Object is developed using the tool Hot Potatoes and all the development process is described, including the adopted methodology and proceedings to follow. Finally the Learning Object prototype is evaluated by a test group, formed by English teachers, in order to check its impact and also the possibility of integration of the prototype and of LO’s in the teaching of English as a foreign language

Medical Content Searching, Retrieving, and Sharing Over the Internet : Lessons Learned From the mEducator Through a Scenario-Based Evaluation

Background: The mEducator Best Practice Network (BPN) implemented and extended standards and reference models in e-learning to develop innovative frameworks as well as solutions that enable specialized state-of-the-art medical educational content to be discovered, retrieved, shared, and re-purposed across European Institutions, targeting medical students, doctors, educators and health care professionals. Scenario-based evaluation for usability testing, complemented with data from online questionnaires and field notes of users' performance, was designed and utilized for the evaluation of these solutions. Objective: The objective of this work is twofold: (1) to describe one instantiation of the mEducator BPN solutions (mEducator3.0 - "MEdical Education LINnked Arena" MELINA+) with a focus on the metadata schema used, as well as on other aspects of the system that pertain to usability and acceptance, and (2) to present evaluation results on the suitability of the proposed metadata schema for searching, retrieving, and sharing of medical content and with respect to the overall usability and acceptance of the system from the target users. Methods: A comprehensive evaluation methodology framework was developed and applied to four case studies, which were conducted in four different countries (ie, Greece, Cyprus, Bulgaria and Romania), with a total of 126 participants. In these case studies, scenarios referring to creating, sharing, and retrieving medical educational content using mEducator3.0 were used. The data were collected through two online questionnaires, consisting of 36 closed-ended questions and two open-ended questions that referred to mEducator 3.0 and through the use of field notes during scenario-based evaluations. Results: The main findings of the study showed that even though the informational needs of the mEducator target groups were addressed to a satisfactory extent and the metadata schema supported content creation, sharing, and retrieval from an end-user perspective, users faced difficulties in achieving a shared understanding of the meaning of some metadata fields and in correctly managing the intellectual property rights of repurposed content. Conclusions: The results of this evaluation impact researchers, medical professionals, and designers interested in using similar systems for educational content sharing in medical and other domains. Recommendations on how to improve the search, retrieval, identification, and obtaining of medical resources are provided, by addressing issues of content description metadata, content description procedures, and intellectual property rights for re-purposed content.Peer reviewe

Towards a metadata standard for field spectroscopy

This thesis identifies the core components for a field spectroscopy metadata standard to facilitate discoverability, interoperability, reliability, quality assurance and extended life cycles for datasets being exchanged in a variety of data sharing platforms. The research is divided into five parts: 1) an overview of the importance of field spectroscopy, metadata paradigms and standards, metadata quality and geospatial data archiving systems; 2) definition of a core metadataset critical for all field spectroscopy applications; 3) definition of an extended metadataset for specific applications; 4) methods and metrics for assessing metadata quality and completeness in spectral data archives; 5) recommendations for implementing a field spectroscopy metadata standard in data warehouses and ‘big data’ environments. Part 1 of the thesis is a review of the importance of field spectroscopy in remote sensing; metadata paradigms and standards; field spectroscopy metadata practices, metadata quality; and geospatial data archiving systems. The unique metadata requirements for field spectroscopy are discussed. Conventional definitions and metrics for measuring metadata quality are presented. Geospatial data archiving systems for data warehousing and intelligent information exchange are explained. Part 2 of the thesis presents a core metadataset for all field spectroscopy applications, derived from the results of an international expert panel survey. The survey respondents helped to identify a metadataset critical to all field spectroscopy campaigns, and for specific applications. These results form the foundation of a field spectroscopy metadata standard that is practical, flexible enough to suit the purpose for which the data is being collected, and/or has sufficient legacy potential for long-term sharing and interoperability with other datasets. Part 3 presents an extended metadataset for specific application areas within field spectroscopy. The key metadata is presented for three applications: tree crown, soil, and underwater coral reflectance measurements. The performance of existing metadata standards in complying with the field spectroscopy metadataset was measured. Results show they consistently fail to accommodate the needs of both field spectroscopy scientists in general as well as the three application areas. Part 4 presents criteria for measuring the quality and completeness of field spectroscopy metadata in a spectral archive. Existing methods for measuring quality and completeness of metadata were scrutinized against the special requirements of field spectroscopy datasets. Novel field spectroscopy metadata quality parameters were defined. Two spectral libraries were examined as case studies of operationalized metadata. The case studies revealed that publicly available datasets are underperforming on the quality and completeness measures. Part 5 presents recommendations for adoption and implementation of a field spectroscopy standard, both within the field spectroscopy community and within the wider scope of IT infrastructure for storing and sharing field spectroscopy metadata within data warehouses and big data environments. The recommendations are divided into two main sections: community adoption of the standard, and integration of standardized metadatasets into data warehouses and big data platforms. This thesis has identified the core components of a metadata standard for field spectroscopy. The metadata standard serves overall to increase the discoverability, reliability, quality, and life cycle of field spectroscopy metadatasets for wide-scale data exchange

Developing a model of teachers' web-based information searching : a study of search options and features to support personalised educational resource discovery

This study has investigated the search options and features teachers use and prefer to\ud have, when personalising their online search for teaching resources. This study\ud focused on making web searching easier for UK teacher practitioners at primary,\ud secondary and post-compulsory levels.\ud In this study, a triangulated mixed method approach was carried out in a two phase\ud iterative case study involving 75 teacher practitioners working in the UK educational\ud setting. In this case study, a sequential evidence gathering method called ‘System\ud Development Life Cycle’ (SDLC) was adapted linking findings obtained from the\ud structured questionnaires, observations and semi-structured interviews in order to\ud design, develop and test two versions of an experimental search tool called\ud “PoSTech!”.\ud This research has contributed to knowledge by offering a model of teachers’ web\ud information needs and search behaviour. In this model twelve search options and\ud features mostly used by teachers when personalising their search for finding online\ud teaching resources via the revised search tool are listed, in order of popularity. A\ud search options is selected by the teacher and features is the characteristic of an option\ud teachers experiences. For example, search options 'Subject', ‘Age Group’, ‘Resource\ud Type’, ‘Free and/ Paid resources’, ‘Search results language’, and search features that\ud ‘Store search options selected by individual teachers and their returned results’.\ud Teachers’ model of web information needs and search behaviour could be used by\ud the Government, teacher trainers and search engine designers to gain an insight into\ud the information needs and search behaviours of teachers when searching for online\ud teaching resources by means of tackling technical barriers faced by teachers, when\ud using the internet.\ud In conclusion, the research work presented in this thesis has provided the initial and\ud important steps towards understanding the web searching information needs and\ud search behaviours of individual teachers, working in the UK educational setting
