A Phenomenological Study of the Lived Experiences of Tagumpay National High School Teachers Involved in Online Learning Action Cell Session

A qualitative phenomenological approach was used in this study to describe the lived experiences of Tagumpay National High School (TNHS) teachers on Online Learning Action Cell (LAC) session. LAC is a school-based professional development for teachers implemented by the Philippine Department of Education (DepEd). Due to teacher’s lack of participation on classroom LAC, a fully-online mode option is explored by offering TNHS teachers Online LAC session using Facebook as a Learning Management System (LMS). To capture the lived experience of teachers, an in-depth interview with a purposive sample of one TNHS teacher is done in the process. The data gathered went through “Hycner’s Explicitation Process” (1999, in Groenewald, 2004) which includes bracketing, delineating, clustering, summarizing and extracting unique themes. Validity and Credibility were accomplished through an intercoder agreement between researchers, Facebook chat records, bracketing, and member checking. Results identified three themes in relation to teacher’s experience of Online LAC session including usefulness, barriers, and preference. Findings revealed the major role of TNHS teacher’s context on how Online LAC is utilized. Recommendations include administrator and expert teacher working with classroom teachers and the inclusion of teachers’ voices as input in the program design, implementation and evaluation stages of Online LAC to better address curriculum needs and facilitate the delivery of high-quality professional development for teachers’ professional growth.

Fipa-Basedreference Architecture for Efficient Discovery and Selection of Appropriatecloud Service Using Cloud Ontology

Cloud Computing (CC) is considered the latest emerging computing paradigm and has brought revolutionary changes in computing technology. With the advancement in this field, the number of Cloud users and service providers are increasing continuously with more diversified services. Consequently, the selection of appropriate Cloud services has become a difficult task for a new Cloud customer. In case of inappropriate selection of a Cloud services, a Cloud customer may face the vendor locked-in issue, data portability, and interoperability issues. To avoid these complexities, a Cloud customer needs to select a required Cloud service at the initial stage of the migration to the Cloud. Many researchers have proposed their approaches to overcome these issues; however, problems still exist in inter-communication standards among Clouds and vendor locked-in issues. This thesis contributed an IEEE-FIPA (Foundation for Intelligent Physical Agent) compliance multi-agent reference architecture for efficient discovery and selection of Cloud services using Cloud ontology. The proposed approach will mitigate the prevailing vendor locked-in issue and also alleviate the portability and interoperability problems in Cloud computing. In order to assess the proposed reference architecture and compare with the state-of-the-art approaches, three different use cases are presented. In addition, a number of experiments have been performed and results are obtained in terms of Precision, Recall and F-measure. The obtained results reveal that our proposed approach performs better in Cloud discovery and selection service with respect to search efficiency, execution, and response time.
