This study investigated the effect of varied digital presentation tools (PowerPoint and Prezi) on the learning performance of students. The research focus was to evaluate how different presentation ...technologies used by class instructors affect the knowledge acquisition of students. A quasi experimental pre- and post-test control group design was adopted to fulfill the research purpose. The educational experiment was completed within 4 weeks. The participants were 78 fifth-grade students from a public elementary school in Taiwan. Students from three classes were divided into three treatment groups: PowerPoint instruction, Prezi instruction, and traditional instruction. Two quizzes (formative evaluation) directly related to learning units were administered to assess the immediate learning outcomes of the students after class. A learning achievement test (summative evaluation) was developed to measure the basic geographical knowledge of the students in a social science class. Two weeks after the summative evaluation was completed, the same learning achievement test with different item numbers (delayed summative evaluation) was employed to assess the long-term learning effects of the students. The results showed that Prezi was a more effective instructional medium for knowledge acquisition compared with traditional instruction. PowerPoint demonstrated instructional effectiveness on only the long-term learning retention of the students compared with traditional instruction. However, no significant difference was observed among the three types of tests in Prezi and PowerPoint instruction.
•Prezi was a more effective instructional medium for knowledge acquisition.•PowerPoint demonstrated instructional benefit on long-term learning retention.•No significant difference was observed between Prezi and PowerPoint instruction.
In academia, funding for conference attendance is limited, and both students and early-career researchers are therefore only able to attend a limited number of conferences. This means that, ...typically, researchers need to choose between attending multiple local and, at times, more affordable conferences, or one or two large, expensive, international conferences. Local and less expensive conferences may be research-specific but will have a smaller audience and lower networking potential. In biological anthropology and bioarchaeology, the majority of these larger annual conferences are held in North America and Western Europe where travel and accommodation costs can be very high for those outside of these regions. These costs, in addition to visa restrictions, reduce the diversity of participants at academic conferences, skewing attendance to students and researchers from the host countries. Not only does this disadvantage individuals outside of the typical host-countries, but it also limits the breadth of academic dialogue, with inclusion in academic conferences determined all too often by financial resources rather than academic value. This paper discusses the demographics and lack of diversity at some of these large conferences and the factors that are known to limit international conference travel. It then presents the benefits of digital presentation methods using Digital Dilemma 2018 as a case study for how digital presentation methods can be combined with physical presentations at minimal cost and time. We hope that this will encourage more conferences to offer a digital presentation option in the future.
Introduction: Final year examinations for postgraduate residents of medical colleges in India were scheduled according to a defined protocol where doctor patient relationship was given utmost ...importance. Due to the currently prevailing pandemic, it has become extremely unsafe to conduct such an examination. So, an innovative method was devised by the Department of Orthopaedics, GMC Srinagar to ensure safety of the examiners and candidates as well as maintaining the required standard of the examination. This method was employed successfully in conducting exit examinations of final year postgraduate residents in this department. Aim: To evaluate the effectiveness by a preformed questionnaire (developed by the faculty of Department of Orthopaedics, GMC Srinagar), Jammu and Kashmir, India of virtual pattern for exit examinations of final year postgraduate residents of medical colleges in India. Materials and Methods: A total number of 10 candidates appeared in the final year (MS Orthopaedics) examination. The conventional format which consisted of assigning patients to the candidates was replaced by a digital presentation format. In this format, the cases were prepared by the faculty, in the form of individual digital presentations for long as well as short cases. Presentation format consisted of detailed history, clinical examination, photographs of any deformity, elicited clinical signs and radiological imaging. A mock test was conducted four weeks before the date of the exam so that the candidates were familiar with the new virtual pattern. A questionnaire was designed to assess the acceptability of the virtual examination. It comprised of 10 questions and each answer was graded on a three point Likert point scale, producing a maximum score of 2 and a minimum score of 0 for each question. Results: Mean total scores for both the groups (examiners and candidates) were 18.25 and 16.9, respectively. The overall outcome regarding the responses was satisfactory in both the groups. The scoring was highest for the safety of the examination in examiner as well as the candidate group. In addition, overall satisfaction also scored the highest among the examiner group. Conclusion: This virtual pattern of examination presents a viable interim alternative to the traditional face to face examination, though it may not replace the latter. The time frame of the pandemic and its trend is difficult to imagine at this point of time, so, the virtual pattern might have to be used for future examinations as well. In addition, this pattern may even be utilised by other departments to frame their examinations.
Institution photo archives are important digital resource with a large proportion of old photos, which makes them of great value in aspects of history and culture. Based on OAIS (Open Archival ...Information System) Model, the
Anhui University Memory Project (AMP) designed and realized a Long-term
Preservation Process, which included a series of standard procedures for lifecycle management. Then digital resource repository and digital memory site were developed according to demands of Anhui University for constructing and presenting memory. This paper aims to introduce the architecture and achievements of
AMP, as well as the design and implementation of long-term preservation process and two distinctive ways of resource organization and memory presentation.
The 21st century has brought several changes to the culture, including the field of museology and monument care. These changes require evolving the methods of cultural heritage presentation. Students ...at our department therefore decided to upgrade their current presentational activities by creating a panel exhibition and developing it as an educational project for primary schools. They chose the topic of Celtic material and spiritual culture, since a lot of evidence of their civilization was found in Slovakia. Besides the exhibition, the project includes a multimedia presentation for teachers, activity sheets for pupils, and a 3D visualisation of a Celtic settlement.

This paper elaborates on the problem of modeling provenance for both physical and digital objects. In particular it discusses provenance according to OAIS (ISO 14721:2003) and how it relates with the ...conceptualization of CIDOC CRM ontology (ISO 21127:2006). Subsequently it introduces an extension of the CIDOC CRM ontology, able to capture the modeling and the query requirements regarding the provenance of digital objects. Over this extension the paper provides a number of indicative examples of modeling provenance in various domains. Subsequently, it introduces a number of indicative provenance query templates, and finally it describes an implementation using Semantic Web technologies.
