Evaluating Visual/Verbal Online Finance Students

This study attempted to determine to what extent audio, video, or some combination of audio/video portions of lecture presentations were helpful in addressing issues related to anxiety, mastering the material presented, and making the class more personal. For several different finance courses, course content with both text and audiovisual material was loaded onto a server using the Adobe Breeze and Adobe Captivate 2 Screen Capture programs on a BLACKBOARD platform. Results based on multiple regression models showed that the new visual and audio portions of the lectures allowed respondents to master the material more effectively, which lead to lower levels of anxiety. Results also showed that making the class more personal through the visual and audio material improved students’ sense that they were mastering the material

Theorizing “Stories About Algorithms” as a Mechanism in the Formation and Maintenance of Algorithmic Imaginaries

In this article, I report from an ethnographic investigation into young adult users of the popular short-video app TikTok. More specifically, I discuss their experience of TikTok’s algorithmic content feed, or so-called “For You Page.” Like many other personalized online environments today, the For You Page is marked by the tension of being a mechanism of digital surveillance and affective control, yet also a source of entertainment and pleasure. Focusing on people’s sense-making practices, especially in relation to stories about the TikTok algorithm, the article approaches the discursive repertoire that underpins people’s negotiation of this tension. Doing so, I theorize the role and relevance of “stories about algorithms” within the context of algorithmic imaginaries as activating users in sense-making processes about their algorithmic entanglements

Multi-modal surrogates for retrieving and making sense of videos: is synchronization between the multiple modalities optimal?

Video surrogates can help people quickly make sense of the content of a video before downloading or seeking more detailed information. Visual and audio features of a video are primary information carriers and might become important components of video retrieval and video sense-making. In the past decades, most research and development efforts on video surrogates have focused on visual features of the video, and comparatively little work has been done on audio surrogates and examining their pros and cons in aiding users' retrieval and sense-making of digital videos. Even less work has been done on multi-modal surrogates, where more than one modality are employed for consuming the surrogates, for example, the audio and visual modalities. This research examined the effectiveness of a number of multi-modal surrogates, and investigated whether synchronization between the audio and visual channels is optimal. A user study was conducted to evaluate six different surrogates on a set of six recognition and inference tasks to answer two main research questions: (1) How do automatically-generated multi-modal surrogates compare to manually-generated ones in video retrieval and video sense-making? and (2) Does synchronization between multiple surrogate channels enhance or inhibit video retrieval and video sense-making? Forty-eight participants participated in the study, in which the surrogates were measured on the the time participants spent on experiencing the surrogates, the time participants spent on doing the tasks, participants' performance accuracy on the tasks, participants' confidence in their task responses, and participants' subjective ratings on the surrogates. On average, the uncoordinated surrogates were more helpful than the coordinated ones, but the manually-generated surrogates were only more helpful than the automatically-generated ones in terms of task completion time. Participants' subjective ratings were more favorable for the coordinated surrogate C2 (Magic A + V) and the uncoordinated surrogate U1 (Magic A + Storyboard V) with respect to usefulness, usability, enjoyment, and engagement. The post-session questionnaire comments demonstrated participants' preference for the coordinated surrogates, but the comments also revealed the value of having uncoordinated sensory channels

User-Generated Tagging and Segmentation of Video Records of Practice: A Tool for Meaning-Marking.

The field of teacher education is consciously shifting its focus to be more “practice-oriented” and increasingly using video as a way of examining teaching practice. However, questions remain about how educators make sense of video and what types of tools and supports are needed. This exploratory study examines the potential of user-generated segmenting and tagging of videos of teaching practice as a tool for marking what educators find salient about teaching and the language they use to describe those phenomena. Data was collected in a teacher education program where video was used extensively for the purposes of learning about and improving teaching practice. There were two participant groups: pre-service teachers (n=6) and teacher educators/educational researchers (n=8). Each participant watched the same 8-minute video of practice and applied segments and tags to the video. The data included segments and tags created by each participant, interviews, and questionnaires; themes in the data were uncovered using content analysis. Interview data was used to interpret participants’ meaning in order to accurately categorize the tags. Using tag gardening strategies, hierarchal and networked tagging language was visualized. Findings indicate that user-generated segment and tag data of video records of practice can provide insight into what participants pay attention to and the language they use to describe that meaning making. This study uncovered three tensions that influenced participants’ segmenting and tagging behavior: findability versus nuance, concerns with being critical, and the need for a social context and community of practice. Educators’ specific and unique needs, purposes, and culture directly affected what participants marked as salient and what tagging language they used, resulting in some misleading segment and tag data. This work provides insights into the design of segmenting and tagging video tools and online communities of practice that support educators’ use of video. This research is particularly relevant to teacher education professionals and designers of tools that support educators’ use of video records of practice, laying the groundwork for further research on using and designing video annotation tools that support the work of teaching and aggregate data about how educators are making sense of videos of teaching.PHDEducational StudiesUniversity of Michigan, Horace H.

Information behaviour videos on YouTube: an exploratory content analysis, case study of INFIDEOS, and call to action

How do landmark concepts of information behaviour appear as videos on YouTube? What do these multimedia artifacts, altogether, suggest about the information behaviour specialty? What might ideal versions of such videos be like? To create an empirical starting point for answering these timely questions, an exploratory content analysis was performed on a sample of 20 educational videos found on YouTube, focusing upon three big ideas of information behaviour: the Information Search Process (Kuhlthau, 1991), Sense-Making (Dervin, 1983) and Berrypicking (Bates, 1989). A coding frame was created with 23 categories and associated subcategories. SurveyMonkey was used to capture, tabulate and present the data. Due to space limitations, not all categories are included in the findings, which are reported as themes with commentary. YouTube’s information behaviour offerings are: cluttered by look-alike videos; uneven in coverage; dominated by librarians and students; and short on scholarly authority. Though singular, featured concepts can be treated thoroughly, most videos have a narrow focus; no scholarly apparatus; and disregard information behaviour’s legacy and culture. Following the content analysis, the author’s YouTube channel of Information Science videos, INFIDEOS, is profiled with attention to its information behaviour resources. Throughout, general video-making strategies are provided.Peer Reviewe

KONSTRUKSI TANDA-TANDA NASIONALISME DALAM VIDEO KLIP MUSIK (Analisis Semiotika Charles Sander Peirce Dalam Video Klip Wonderland Indonesia By : Alffy Rev Ft. Novia Bachmid Chapter 1)

This research aims to gain an understanding of the message content in Wonderland Indonesia Chapter 1. Wonderland Indonesia is a creation by Indonesian youth, and its purpose is to serve as a gift for the 76th anniversary of the nation's independence. It trended as number 1 on YouTube in the music category, and received many positive comments stating that watching the Wonderland Indonesia video can evoke a sense of nationalism. The purpose of creating the Wonderland Indonesia music video is to reintroduce Indonesian culture and encourage young people to once again memorize regional songs, presented with an EDM (Electronic Dance Music) music arrangement. This research employs a qualitative, descriptive approach, with the analytical tool being Charles Sender Peirce's theory. The findings of this study reveal that Indonesia, as an archipelagic nation, possesses stunning natural beauty and a heritage that has endured through the ages, making it a culturally rich and multicultural country. The research also highlights Indonesia's history of striving for independence and its classical era, such as the Majapahit era. It conveys a message to the younger generation to always serve their nation

Moving from theory to practice in the design of web-based learning from the perspective of Constructivism

This paper describes the design of a web-based learning module according to a framework drawing on constructivist theories. The aim was to operationalize concepts such as authenticity, collaborative knowledge sharing, sense-making and viewing multiple perspectives as they relate to the design of e-learning opportunities. The prototypical module was designed for practitioners such as teachers and structured around interpreting and responding to a problem. The module consists of a problem model and relies on use of a discussion forum and a shared workspace to support negotiation of interpretation and experience. Also included are 60 streamable video segments presenting multiple perspectives on the problem. Results of the design process provide insight into ways in which constructivist principles and concepts can be translated into practical solutions for the provision of e-learning content. The module illustrates a way in which learning experiences can inform and be informed by practice

Thriller theory as a panacea for nation building and quality production in Nollywood films: Obi’s Idemili season 1 as paradigm

Film is seen as an effective educational tool for correcting societal ills in the sense that it presents the people’s cultures and raises critical questions on the norms and traditions obtainable in any society; therefore any attempt to misinterpret the intended message of this medium through sub standard production affects the existential essence of a people. This study presents the problems of filmmakers and film making process in Nigeria video film industry and points out how the divorce of theory from practice has affected professionalism in the industry. The study proposes a radical restructuring of the film industry in Nigeria in order to sustain what it has achieved for further development. To this end, it suggests a fusion of theory and practice in order to sustain growth and development that started in the industry over two decades ago. This will enable film makers in the industry to achieve a viable integration of the whole processes of film making to reach the pick of professionalism. This trend should serve as catalyst for flushing out quacks and amateurs who parade themselves as filmmakers in the industry. The researcher zeros in the study on a new Nigerian thriller Home video film: Idemili season 1 (2014) so as to explore the service of thriller theory to film making in the Nollywood Industry. The aim is to ascertain how this theory could be used as mechanism for sustainability and growth in Nigeria Film Industry. Case study and content analysis research approaches of the qualitative research method are adopted for the realization of research objectives

Temporal hybridity: Mixing live video footage with instant replay in real time

Copyright @ 2010 ACMIn this paper we explore the production of streaming media that involves live and recorded content. To examine this, we report on how the production practices and process are conducted through an empirical study of the production of live television, involving the use of live and non-live media under highly time critical conditions. In explaining how this process is managed both as an individual and collective activity, we develop the concept of temporal hybridity to explain the properties of these kinds of production system and show how temporally separated media are used, understood and coordinated. Our analysis is examined in the light of recent developments in computing technology and we present some design implications to support amateur video production.The research was partly made possible by a grant from the Swedish Governmental Agency for Innovation Systems to the Mobile Life VinnExcellence Center, in partnership with SonyEricsson, Ericsson, Microsoft Research, Nokia Research, TeliaSonera and the City of Stockholm
