nl The Influence of Augmented Reality Face Filter Addiction on Online Social Anxiety: A Stimulus-Organism-Response Perspective By Published On :: 2024-04-18 Aim/Purpose: This study aims to analyze the factors that influence user addiction to AR face filters in social network applications and their impact on the online social anxiety of users in Indonesia. Background: To date, social media users have started to use augmented reality (AR) face filters. However, AR face filters have the potential to create positive and negative effects for social media users. The study combines the Big Five Model (BFM), Sense of Virtual Community (SVOC), and Stimuli, Organism, and Response (SOR) frameworks. We adopted the SOR theory by involving the personality factors and SOVC factors as stimuli, addiction as an organism, and social anxiety as a response. BFM is the most significant theory related to personality. Methodology: We used a quantitative approach for this study by using an online survey. We conducted research on 903 Indonesian respondents who have used an AR face filter feature at least once. The respondents were grouped into three categories: overall, new users, and old users. In this study, group classification was carried out based on the development timeline of the AR face filter in the social network application. This grouping was carried out to facilitate data analysis as well as to determine and compare the different effects of the factors in each group. The data were analyzed using the covariance-based structural equation model through the AMOS 26 program. Contribution: This research fills the gap in previous research which did not discuss much about the impact of addiction in using AR face filters on online social anxiety of users of social network applications. Findings: The results of this study indicated neuroticism, membership, and immersion influence AR face filter addiction in all test groups. In addition, ARA has a significant effect on online social anxiety. Recommendations for Practitioners: The findings are expected to be valuable to social network service providers and AR creators in improving their services and to ensure policies related to the list of AR face filters that are appropriate for use by their users as a form of preventing addictive behavior of that feature. Recommendation for Researchers: This study suggested other researchers consider other negative impacts of AR face filters on aspects such as depression, life satisfaction, and academic performance. Impact on Society: AR face filter users may experience changes in their self-awareness in using face filters and avoid the latter’s negative impacts. Future Research: Future research might explore other impacts from AR face filter addiction behavior, such as depression, life satisfaction, and so on. Apart from that, future research might investigate the positive impact of AR face filters to gain a better understanding of the impact of AR face filters. Full Article
nl Perceived service process in e-service delivery system: B2C online retailers performance ranking by TOPSIS By www.inderscience.com Published On :: 2024-04-30T23:20:50-05:00 Significant work in service domain has focused on customer journey within e-service delivery system process (e-SDSP). Few studies have focused on process-centric approach to customer journey during delivery of e-services. This study aims to investigate the performance assessment of three online retailers (alternatives) using perceived service process during different stages of e-SDSP as a criterion for decision-making. TOPSIS is used in this paper to rate and evaluate multiple online retailers. Based on perceived service process as the criterion, results show that online retailer-2 outperforms other two online retailers. This study is one of the first to rate online retailers by utilising customer-perceived service process (latent variables) as a decision-making criterion throughout e-SDSP. The finding suggests that perceived searching process is the most essential criterion for decision-making, followed by the perceived after-sales service process, the perceived agreement process, and the perceived fulfilment process. Implications, limitations, and future scope are also discussed. Full Article

nl Adoption of Online Network Tools by Minority Students: The Case of Students of Ethiopian Origin in Israel By Published On :: 2015-12-14 Students of Ethiopian origin belong to one of the weakest sectors in the Jewish population of Israel. During their studies they have to deal with social alienation, cultural gaps, economic hardships, and racial stereotypes which reduce their chances to successfully complete their academic degree. In this respect, the present research asks whether online social media could provide those youngsters with tools and resources for their better social integration and adaptation to the academic life. For this purpose, the study was conducted in one of Israel’s largest academic colleges while adopting a design-based research approach, which advanced gradually on a continuum between ‘ambient’ and ‘designed’ technology-enhanced learning communities. The interventions applied for this study aimed at examining how they may encourage students of Ethiopian origin to expand their activities in the online social learning groups. The findings indicate that the main pattern of students of Ethiopian origin online participation was peripheral and limited to viewing only. Nevertheless, the level of their online activity has been improved after a series of two interventions, which also led to a slight improvement in indicators of their social integration and in a change in their usage of online learning groups from social to academic uses.

nl Design Principles for Promoting Intergroup Empathy in Online Environments By Published On :: 2016-12-26 This study examined a professional development program designed to support Civics teachers in their efforts to promote empathy among Israeli Jewish students towards Israeli Arabs. The design rationale for the program is that teachers should experience empathic processes themselves before supporting their students in such an endeavor and that meaningful empathic processes can occur online if activities are properly designed. All phases of the program were designed to support teachers to participate as part of an online community of practice. Sixty Jewish teachers participated in two iterations of the design study. Refinements were made in the second iteration to provide teachers with explicit definitions of empathy and specific instructions for reflection. Findings indicate that these changes were reflected in higher degrees of empathic responses among teachers. Teachers also indicated that being a part of an online learning community contributed to the learning process they experienced during the program. We interpret this as a first step in enabling teachers to assist their students to develop a more empathetic approach toward the minority group and conclude with a discussion of recommended design principles for promoting such an approach.

nl Learning from Online Modules in Diverse Instructional Contexts By Published On :: 2016-06-03 Learning objects originally developed for use in online learning environments can also be used to enhance face-to-face instruction. This study examined the learning impacts of online learning objects packaged into modules and used in different contexts for undergraduate education offered on campus at three institutions. A multi-case study approach was used, examining learning impacts across a variety of course subjects, course levels (introductory and advanced undergraduate), student levels (undergraduate and graduate), and instructional goals (i.e., replacement for lecture, remediation). A repeated measures design was used, with learning data collected prior to viewing the online module, after completion of the module, and at the end of the semester. The study provided a broad examination of ways that online modules are typically used in a college classroom, as well as measured learning effectiveness based on different instructional purpose and usage contexts. Results showed the effectiveness of the modules in serving as a substitute for classroom lecture, remediation of course prerequisite material, introduction to content with follow-up lab practice, and review for final exams. In each of these cases, the use of the modules resulted in significant learning increases, as well as retention of the learning until the end of the semester. Full Article
nl A Learning Analytics Approach for Evaluating the Impact of Interactivity in Online Video Lectures on the Attention Span of Students By Published On :: 2017-12-25 Aim/Purpose: As online video lectures rapidly gain popularity in formal and informal learning environments, one of their main challenges is student retention. This study investigates the influence of adding interactivity to online video lectures on students’ attention span. Background: Interactivity is perceived as increasing the attention span of learners and improving the quality of learning. However, interactivity may be regarded as an interruption, which distracts students. Furthermore, adding interactive elements to online video lectures requires additional investment of various resources. Therefore, it is important to investigate the impact of adding interactivity to online video lectures on the attention span of learners. Methodology: This study employed a learning analytics approach, obtained data from Google Analytics, and analyzed data of two Massive Open Online Courses (MOOCs) that were developed by the Open University of Israel in order to make English for academic purposes (EAP) courses freely accessible. Contribution: The paper provides important insights, based on quantitative empirical research, on: integrating interactive elements in online videos; the impact of video length; and differences between two groups of advanced and basic learners. Furthermore, it demonstrates how learning analytics may be used for improving instructional design. Findings: The findings suggest that interactivity may increase the attention span of learners, as measured by the average online video lecture viewing completion percentage, before and after the addition of interactivity. However, when the lecture is longer than about 15 minutes, the completion percentages decrease, even after adding interactive elements. Recommendations for Practitioners: Adding interactivity to online video lectures and controlling their length is expected to increase the attention span of learners. Recommendation for Researchers: Learning analytics is a powerful quantitative methodology for identifying ways to improve learning processes. Impact on Society: Providing practical insights on mechanisms for increasing the attention span of learners is expected to improve social inclusion. Future Research: Discovering further best practices to improve the effectiveness of online video lectures for diverse learners. Full Article
nl Going Behind the Scenes at Teacher Colleges: Online Student Knowledge Sharing through Social Network Technologies By Published On :: 2017-12-25 Aim/Purpose: The present study aims to describe existing peer-to-peer, social network-based sharing practices among adult students in teacher colleges. Background: Ubiquitous social network sites open up a wide array of possibilities for peer-to-peer information and knowledge sharing. College instructors are often unaware of such practices that happen behind the scenes. Methodology: An interpretative, qualitative research methodology was used. Thirty-seven Israeli students at a teacher college in Israel participated in either focus group discussions of (N = 29) or in-depth interviews (N = 8). Contribution: Whereas knowledge sharing has been a main focus of research in organizational and information sciences, its relevance to educational settings has thus far been underscored. Recent research shows that peer–to-peer knowledge sharing is wide-spread among teenage students. The current study extends that work to an adult student population. Findings: The findings show that knowledge sharing of this type is a common and even central feature of students’ college life and study behavior. It takes place through a variety of small and larger social network-based peer groups of different formations, including mostly college students but at time also practicing, experienced teachers. Sharing groups are formed on the spot for short term purposes or are stable, continuous over longer time periods. The contents shared are predominantly lesson summaries, material for exams, reading summaries, and lesson plans. They are used immediately or stored for future use, as students have access to vast data bases of stored materials that have been compiled throughout the years by students of previous cohorts. Teacher students mentioned a range of reasons for sharing, and overall regard it very positive. However, some downsides were also acknowledged (i.e., superficial learning, exclusion, attentional overload, and interruptions). Recommendations for Practitioners: College faculty and teaching staff should be cognizant and informed about these widespread peer-based knowledge sharing practices and consider whether perhaps changes in teaching formats and task assignments are required as a result. Future Research: Future research should extend this work to other higher education settings, cultures and countries, and should map the perceptions of higher education teaching staff about peer-to-peer, online knowledge sharing.

nl 21st Century Skills: Student Perception of Online Instructor Role By Published On :: 2018-07-15 Aim/Purpose: This research inquires how students perceive the role of Technology Education and Cultural diversity (TEC) instructors in improving their 21st century skills. In addition, this study examines the students’ preferred learning style: face to face, synchronous and asynchronous. Background: 21st century skills include, among others, collaboration, Information and Communication Technology (ICT) skills, higher order thinking, and multicultural communication. These skills are core elements for modern life and are the focus of this study as teacher critical career and life skills. This article presents the uniqueness of the TEC model, which provides a strategy to develop gradually various 21st century skills for teacher training in a multicultural technologically rich environment. Methodology: This study examined (a) the level of ICT skills students acquire from the courses; (b) students’ perceptions of the instructor role in developing 21st century skills; and (c) students’ preferred learning style. A questionnaire was delivered to 99 students, who participated in courses based on the TEC model. Students from eight different Teacher Education Colleges and different cultural backgrounds – Arabs, Jews, religious, and secular – participated in this study. Contribution: This study could shed light on the instructor’s role as a facilitator in developing students’ 21st century skills in a multicultural society. This study may provide a model and ideas for policy makers in teacher training programs to employ 21st century skills along with continuous development and adaptation to suit the rapid changing reality. A larger study needed to examine additional aspects of the 21st century skills in the teacher training programs in general and in multicultural societies in particular. Findings: The findings show that students complete the course with a high level of ICT skills, and that their preferred learning communication style was face-to-face (F2F) (45.45%) and blended method (43.43%), over the fully online (11.11%). Regarding online learning, students mostly preferred the mixed method of synchronous and asynchronous (59%), followed by asynchronous (29%), and synchronous (12%). As to student preference of the instructor role of enhancement, the results were prioritized as follow: Higher order thinking (M=3.99), online group collaboration (M=3.87), multicultural communication awareness (M=3.82), pedagogical use of digital tools (M=3.73). Recommendations for Practitioners: Teacher education lecturers ought to: (1) design the online courses in a way that integrates F2F meetings and both synchronous and asynchronous methods; and (2) employ the wide range of skills in TEC courses that comply with 21st century principles; hence, the importance of widening such courses in teacher education colleges. Recommendation for Researchers: It is recommended to perform a similar study using a pre-post method, as well as taking into consideration cultural uniqueness (such as language differences) and group comparison, where we can identify the effective components of the course design that would lead to a higher level of 21st century skills competencies among teachers. Impact on Society: 21st century skills are life skills, hence developing these skills in an appropriate educational setting reflects better utilization among all the members of society. Future Research: More research should be done to widen the knowledge and address the importance of the instructor role as a course designer and facilitator in order to turn 21st century learning into a more meaningful and relevant one.

nl Enabling IT Self-leadership in Online Education By Published On :: 2021-01-21 Aim/Purpose: This paper investigates the factors contributing to student IT self-leadership in online education using an exploratory study. Specifically, our goal was to understand whether the instructors’ transformational IT leadership and the students’ personal innovativeness with IT contributed to student IT self-leadership. Background: The study was conducted in an online course. While today’s students are expected to be IT natives, they still lack the skills to find and learn technologies on their own. This is problematic for both online education and students’ future careers. Directed-teaching methods are not appropriate to solve this kind of problem, a more constructivist teaching method is appropriate. We recommend that instructors adopt transformational IT leadership to set norms around technology use, to be role models in using online course technologies with utmost knowledge, and to encourage and support the students in their use of IT. Methodology: An exploratory research is conducted with 46 students in an online management information systems course at a public university. The data were analyzed using PLS structural equation modeling technique. Contribution: This paper introduces the unique concepts of student IT self-leadership and instructors’ transformational IT leadership by adapting concepts from the self-leadership and transformational leadership theories. IT self-leadership refers to the ability to intentionally influence one’s own thinking, feeling, and actions toward the use of IT to reach one’s work and life goals. To increase IT self-leadership, students should try new technologies as much as possible. Instructors should set up norms about trying new technologies, troubleshooting one’s own issues, and play a supportive and encouraging role, rather than employing directed-teaching methods. Findings: IT self-leadership skills are the ability to intentionally influence one’s own thinking, feeling and actions towards the use of IT to reach one’s work and life goals. The findings show that instructors’ transformational IT leadership as well as students’ innovativeness with IT contributes to students’ IT self-leadership. Recommendations for Practitioners: Practitioners may consider exhibiting transformational IT leadership skills including (1) giving encouragement about IT use, (2) fostering trust, (3) encouraging thinking about IT problems in new ways, (4) being clear about their values about IT by practicing what they preach in their IT use, and (5) inspiring students by being highly competent in IT. Potential ways that the instructors can exhibit these skills are discussed in the paper. Recommendation for Researchers: Researchers are recommended to include IT-self leadership of both students and instructors in their investigations on learning success. Furthermore, the inclusion of transformational IT leadership in new studies of teaching and learning success is recommended. Impact on Society: This paper includes students as part of the solution to challenges students face in online courses rather than treating them like passive recipients of educational changes. Thereby, it helps teachers and students to work together for a better solution to educational disruptions. Future Research: Studies should be conducted to determine other antecedents and outcomes of IT self-leadership. Research is needed on specific ways practitioners can increase their IT transformational leadership. While this paper introduced how the instructor of the exploratory study provided transformational IT leadership, more than one way of reaching each goal was practiced. Future research should test the connection between each transformational IT leadership behavior presented here and its outcome. Full Article
nl An Exploratory Study of Online Equity: Differential Levels of Technological Access and Technological Efficacy Among Underserved and Underrepresented Student Populations in Higher Education By Published On :: 2020-11-14 Aim/Purpose: This study aims to explore levels of Technological Access (ownership, access to, and usage of computer devices as well as access to Internet services) and levels of Technological Efficacy (technology related skills) as they pertain to underserved (UNS) and underrepresented (UNR) students. Background: There exists a positive correlation between technology related access, technology related competence, and academic outcomes. An increasing emphasis on expanding online education at the author’s institution, consistent with nationwide trends, means that it is unlikely that just an increase in online offerings alone will result in an improvement in the educational attainment of students, especially if such students lack access to technology and the technology related skills needed to take advantage of online learning. Most studies on levels of Technological Access and Technological Efficacy have dealt with either K-12 or minority populations with limited research on UNS and UNR populations who form the majority of students at the author’s institution. Methodology: This study used a cross-sectional survey research design to investigate the research questions. A web survey was sent to all students at the university except first semester new and first semester transfer students from various disciplines (n = 535). Descriptive and inferential statistics were used to analyze the survey data. Contribution: This research provides insight on a population (UNS and UNR) that is expanding in higher education. However, there is limited information related to levels of Technological Access and Technological Efficacy for this group. This paper is timely and relevant as adequate access to technology and technological competence is critical for success in the expanding field of online learning, and the research findings can be used to guide and inform subsequent actions vital to bridging any educational equity gap that might exist. Findings: A critical subset of the sample who were first generation, low income, and non-White (FGLINW) had significantly lower levels of Technological Access. In addition, nearly half of the survey sample used smartphones to access online courses. Technological Efficacy scores were significantly lower for students who dropped out of or never enrolled in an online course. Transfer students had significantly higher Technological Efficacy scores while independent students (determined by tax status for federal financial aid purposes) reflected higher Technological Efficacy, but at a marginally lower level of significance. Recommendations for Practitioners: Higher education administrators and educators should take into consideration the gaps in technology related access and skills to devise institutional interventions as well as formulate pedagogical approaches that account for such gaps in educational equity. This will help ensure pathways to sustained student success given the rapidly growing landscape of online education. Recommendation for Researchers: Similar studies need to be conducted in other institutions serving UNS and UNR students in order to bolster findings and increase awareness. Impact on Society: The digital divide with respect to Technological Access and Technological Efficacy that impacts UNS and UNR student populations must be addressed to better prepare such groups for both academic and subsequent professional success. Addressing such gaps will not only help disadvantaged students maximize their educational opportunities but will also prepare them to navigate the challenges of an increasingly technology driven society. Future Research: Given that it is more challenging to write papers and complete projects using a smartphone, is there a homework gap for UNS and UNR students that may impact their academic success? What is the impact of differing levels of Technological Efficacy on specific academic outcomes of UNS and UNR students? Full Article

nl Facilitating Scientific Events Guided by Complex Thinking: A Case Study of an Online Inter/Transdisciplinary Advanced Training School By Published On :: 2022-03-12 Aim/Purpose This paper aims to illustrate, through an exploratory ideographic case study, how a Complex Thinking framework can inform the design of scientific events and the facilitation of scientific Inter and Transdisciplinary groups towards positive emergent outcomes, both at the level of the functioning of the group and the collective complexity of their thinking. Moreover, it aims to show how the choice of facilitation strategies can contribute to positive emergent outcomes in the context of a fully online event, with its inherent constraints. Finally, this study aims to conduct an exploratory qualitative evaluation of the participants’ experiences during School, with a focus on the processes and how they relate to the aims of the School and the goals of the facilitation. Background Science needs to embrace modes of knowing capable of generating more complex (differentiated, integrated, recursively organized, emergent), ecologically fit, and creative responses, to meet the complexity of the world’s challenges. New formats and strategies are required that attend to the facilitation of Inter and Transdisciplinary scientific events and meetings, towards creative and complex outcomes. A Complex Thinking framework provides suggestions for the facilitation of Inter and Transdisciplinary meetings and events through targeting key properties which may lead to the emergence of complex and creative outcomes. Methodology We adopt an ideographic case study approach to illustrate how a complex systems approach, in particular a Complex Thinking framework, grounded in an enactive view of cognition, guided the design choices and the facilitation strategies of an online Inter and Transdisciplinary Advanced Training School (Winter School). We aim to illustrate how the facilitation strategies were selected and used to promote deep and creative interactions within the constraints of an online environment. We adopt an exploratory qualitative approach to investigate the participants’ reports of their experiences of the School, in light of the principles and goals that guided its design and facilitation. Contribution This paper opens a new area of theoretical and applied research, under the scope of a Complex Thinking framework, focused on the facilitation of Inter and Transdisciplinarity at scientific events, meetings, and discussions towards complex and creative outcomes. Findings The results of the exploratory qualitative analysis of the participants’ experiences regarding the event suggest a critical role of its methodology in fostering rich, deep, and constructive interactions, in leading to the emergence of a collective group experience, to the integration of ideas, and in facilitating transformative personal experiences, under the effects of the emergent group processes. It suggests that the strategies employed were successful, anticipating and overcoming the particular constraints of an online event. Recommendations for Practitioners This case study suggests that a Complex Thinking framework can fruitfully guide the design of facilitation strategies and activities for scientific events and meetings, activating a number of key relational processes that contribute to or boost the emergence of positive group experiences and the production and integration of novel ideas. Recommendations for Researchers This study calls for action-oriented and applied research focused on the developmental evaluation of innovations, regarding the facilitation of scientific creativity and integration, within the scope of a Complex Thinking approach. Impact on Society This paper calls for new modes of organization and formats of scientific activities, suggesting that Inter and Transdisciplinary events and meetings may benefit from intentional management and facilitation of interactions between participants to produce transformative impacts. It demonstrates the importance of the organizational principles used to plan and run events that engage multiple and various societal agents, from academics to practitioners and social activists, towards enhancing their richness and relevance to complex real-world challenges. Future Research This study highlights the need for process-focused systematic case study research using complex systems-informed designs to explore how and which facilitation strategies may promote which (interaction of) properties of Complex Thinking and associated processes and how, and under which conditions, these lead to more complex and creative outcomes.

nl An MINLP model for project scheduling with feeding buffer By www.inderscience.com Published On :: 2024-10-02T23:20:50-05:00 This study addresses a critical chain project scheduling (CCPS) problem regarding the feeding buffer. The main contribution of this study lies in determining the critical chain when the feeding buffer is considered along with the project buffer, a less addressed issue in the critical chain literature. Using a mixed-integer nonlinear programming (MINLP) model, the critical chain of a project with no break-down and no overflow is found. Moreover, the impact of the feeding buffer on the criticality of activities is discussed. The problem is solved using the Lingo software package for validation in small-sized instances. Since the CCPS is known as an NP-hard problem, a genetic algorithm (GA) is also designed to solve large-scale instances. The algorithm's performance is confirmed using various project scheduling library test problems. Sensitivity analysis is implemented based on some crucial parameters, and the critical chain is analysed after conducting several experiments. It is shown how considering the feeding buffer makes different critical chains and how shortlisting activities and resources are optimally managed. Full Article
nl THE ONLINE SHADOW OF OFFLINE SIGNALS: WHICH SELLERS GET CONTACTED IN ONLINE B2B MARKETPLACES? By amj.aom.org Published On :: Wed, 22 Jul 2015 14:48:34 +0000 This article extends the understanding of what impels buyers to contact particular sellers in online business-to-business (B2B) marketplaces, which are typically characterized by sparse social structures and concomitant limitations in observing social cues. Integrating an institutional perspective with signaling theory, our core argument is that offline seller characteristics that are visible online—in particular, geographic location and legal status—convey credible signals of seller behavior because they provide buyers with information on sellers' local institutional quality and the institutionally-induced obligations and controls acting on sellers. Using unique data from a large Italian online B2B marketplace between the fourth quarter of 1999 and July 2001, we find that both sellers' local institutional quality and their legal statuses affect a buyer's likelihood of contacting a seller. Moreover, consistent with the idea that a buyer's own local institutional quality generates a relevant reference point against which sellers are evaluated, we find that a buyer is progressively more likely to contact sellers the higher their local institutional quality relative to the buyer. Jointly, our findings imply that in online B2B marketplaces, signals conveyed by sellers' geographic locations and legal statuses may be substantive sources of competitive heterogeneity and market segmentation.
