Behavioral modeling based on cloud computing and target user recommendation for English cloud classroom

The English cloud classroom learning system provides a simple and effective way to access cloud-based training and learning materials. Student records based on behavioral modeling and interactive volume are assumed that the degree of student participation in the course measure. Previous studies, typically the frequency of student activities while ignoring temporary information. Analysis of Students' Activities in the course over time. According to the online classroom activity data, similar behavior change with time students are clustered. These results are three different groups. A large majority of inactive students. Another group to active throughout the students. However, a group of students to the event, but their activity will be reduced throughout the course. These student groups exhibit different performance. Overall students more active, the better the results. In addition to these general trends, also identified a trend of alternative courses that can be found, for example, becomes an active group of students in the course. It suggests that students' behavior is identified from a single course of conduct than the more complex, multi-mode learning activities course. More research is essential. In this study, investigated the Portuguese teachers 'views on classroom management, the relationship between self-off and the efficacy of teachers' and teachers' perception of classroom behavioral teachers' perception of time. Use mediator and moderator variables on the cloud classroom management, and teachers of English teachers perceive the relationship between classroom conditions were cheating process analysis.     

A study of social participation and knowledge sharing in the teachers' online professional community of practice

To facilitate professional development of teachers in the online context, the online community of practice (CoPs) has become an important platform in which individuals with similar interests or common goals get together to share their resources, develop working strategies, solve problems, and improve individual as well as organizational performance. In this study, we have collected self-reported knowledge-sharing behaviors from 321 members of the largest online professional CoP of teachers in Taiwan. The results show that closer connections among online CoP members can lead to greater recognition of and altruism towards others. Moreover, performance expectation and self-efficacy belief play essential roles in knowledge-sharing participation. Thus, the development of social relationships among online teacher members helps them obtain potential resources and reliable support through their social network. Also, teachers' membership in the online professional CoP fosters a prosocial attitude that heightens their willingness to share useful resources and solve other members' problems, both emotionally and instrumentally. Consequently, knowledge-sharing behaviors, in terms of knowledge giving and knowing receiving, are significantly predicted by prosocial commitment and performance expectation respectively. The implications to both research and practice are provided in this paper.     

Exploring the use of educational technology in primary education: Teachers' perception of mobile technology learning impacts and applications' use in the classroom

Mobile technology has become popular worldwide with a broad range of users, including students from all levels of education. Although the impact of mobile technology in classrooms has been extensively studied, less is known about teachers' perceptions of how mobile technology impacts in learning and its relation to Applications (Apps) use in the classroom. This state of affairs is problematic since we know that teachers' perceptions have a great influence on their teaching practices. This study used survey data gathered from 102 teachers of 12 different primary schools in Spain. The questionnaire collected data about teachers' individual information, teachers' perceptions on the impact of mobile technology in learning, and use of a set of selected Apps in the classroom. Findings suggest that facilitating access to information and increasing engagement to learning are the two main impacts of mobile technology in the classroom. Findings also show that the choice of Apps is related to the teachers' perception of how mobile technology impacts in learning. Findings could help teachers to take advantage of the combination of affordances of mobile technology and Apps that actually improve some aspects of learning practice.     

Learning Virtual Community Loyalty Behavior From a Perspective of Social Cognitive Theory

Drawing upon social cognitive theory (SCT), this research postulates several personal and environmental factors as key drivers of virtual community loyalty behavior in online settings. An empirical testing of this model, by investigating undergraduate students' participation in communities of online games, reveals the applicability of SCT in virtual communities. The study's test results show that the influences of both affective commitment and social norms on community loyalty behavior are significant, whereas the influences of both exchange ideology and social support on community loyalty behavior are insignificant. This research contributes to the online community literature by assessing critical antecedent factors to the unexplored area of community loyalty behavior, by validating idiosyncratic drivers of community loyalty behavior and by performing an operationalization of affective commitment and social norms in a virtual world. Last, managerial implications and limitations of this research are provided.     

Professional development to enhance teachers' practices in using information and communication technologies (ICTs) as cognitive tools: Lessons learned from a design-based research study

Technology integration in K-12 classrooms is usually overly teacher-centered and has insufficient impact on students' learning, especially in enhancing students' higher-order cognitive skills. The purpose of this project is to facilitate science teachers' use of information and communication technologies (ICTs) as cognitive tools to shift their practices from traditional teacher-centered methods to constructivist, student-centered ones. This paper describes the outcomes and lessons learned from an application of design-based research (DBR) in the implementation and refinement of a teacher professional development (PD) program that is a key component of the overall project. This DBR study involved 25 middle-school science teachers from 24 schools whose implementation of cognitive tools with their students in science classrooms and virtually through a social networking site were observed over four years. A mixed-methodology was utilized to examine the impact of the cognitive tools intervention on teachers' classroom practices and students' development of new literacy skills. Identifying reusable design principles related to technology integration was another focus of the DBR study. The results revealed teachers' positive changes in their classroom practices by gradually allowing students to take control over the use of technology, and positive impact on students' ICT skills and science learning. Design principles for future professional development programs aimed at preparing teachers to adopt a cognitive tools approach are described.     

Peer modeling and innovation adoption among teachers in online professional development

This paper draws on three years of data from an online course on educational technology for practicing teachers, in which a goal was for teachers to develop a web-based application they could use in their own teaching. Based on analyses of discussion forums and teachers' course projects, we found that iterations of the course evolved over the years from being a loose association of peers involved in vastly different development projects with different tools, to a community of designers involved in a common endeavor, as more and more students chose the same open-source learning management system for their course projects. We tracked what factors seemed to affect how many and which teachers chose which development technologies, and how the process of making these choices evolved with the increased role of designed and emergent forms of peer modeling. We situate these findings in the literature on teacher professional development and technology use, arguing that existing conversations need to attend to the important role that peers play in teachers' learning and innovation adoption, particularly in online learning environments.     

Revisiting cyberbullying: Perspectives from Taiwanese teachers

Cyberbullying among students has received extensive attention from researchers and educators. Most research is, however, based on student reports while teachers' perceptions of this aggressive behavior among students have rarely been studied. We surveyed 2821 Taiwanese teachers on their perceptions of cyberbullying among students, including the types and tools, the ability to remain anonymous, students' responses, and their own practices of handling cyberbullying incidents at school. The results showed that teachers believed that the circulation of embarrassing pictures and videos was the most prevalent type of cyberbullying but that instant messaging was the most frequently used tool. Our findings also revealed teachers' tendency of overestimating students' willingness to report cyberbullying. The students' grade level that the teachers taught and whether they take on administrative duties were found to influence their perceptions of student cyberbullying. We found that teachers were not confident to handle cyberbullying incidents and we suggest that anti-cyberbullying training be included in teacher education.     

The dark side of social networking sites:Understanding phishing risks

LinkedIn, with over 1.5 million Groups, has become a popular place for business employees to create private groups to exchange information and communicate. Recent research on social networking sites (SNSs) has widely explored the phenomenon and its positive effects on firms. However, social networking's negative effects on information security were not adequately addressed. Supported by the credibility, persuasion and motivation theories, we conducted 1) a field experiment, demonstrating how sensitive organizational data can be exploited, followed by 2) a qualitative study of employees engaged in SNSs activities; and 3) interviews with Chief Information Security Officers (CISOs). Our research has resulted in four main findings: 1) employees are easily deceived and susceptible to victimization on SNSs where contextual elements provide psychological triggers to attackers; 2) organizations lack mechanisms to control SNS online security threats, 3) companies need to strengthen their information security policies related to SNSs, where stronger employee identification and authentication is needed, and 4) SNSs have become important security holes where, with the use of social engineering techniques, malicious attacks are easily facilitated.     

Consuming and creating: Early-adopting science teachers' perceptions and use of a wiki to support professional development

Many teachers have little opportunity to share and discuss their practice in the course of a normal school day beyond chance meetings in the staff room. Such a lack of opportunity can leave many teachers feeling isolated. However, online resources are continuously providing teachers with greater opportunities to engage with other teachers. This research studied early-adopting New Zealand science teachers' perceptions and integration of one such online resource, a wiki, for professional development. The wiki was developed to support teacher portfolios consisting of mediums called Content Representations (CoRes) and Pedagogical and Professional-experience Repertoires (PaP-eRs). Initial interviews were conducted with six teachers and were followed by case studies of three of these teachers. Data included pre/post interviews, field notes from feedback on observations, and teachers' use of the wiki. Findings discuss important factors organised around three themes in relation to teacher perceptions and engagement in knowledge sharing on a wiki: technology competence, technology utility, and technology resourcing.     

Competition and Information Deception in Online Social Networks

This study empirically examines the role of competition in determining intentions toward personal information deception (PID) among users of online social network (OSN) sites. PID refers to OSN users intentionally misrepresenting or refusing to disclose online personal information. The research proposes that consumers’ intentions toward PID depend on their desire for online competition with other OSN users, which in turn depends on user appraisals of available status and hedonic benefits, as well as established social norms around competition. An analysis of data gathered from 499 OSN participants (students enrolled at a state university in the southeastern United States) shows that competitive desires represent an important antecedent of PID behavior in OSN contexts. Theoretical and practical implications of the research are also discussed.     

Preservice and inservice teachers' pedagogical reasoning underlying their most-valued technology-supported instructional activities

We examined teachers' pedagogical reasoning for and the technological knowledge underlying their most-valued technology-supported activities for teaching and learning. Data from 140 preservice and 100 inservice teachers included open-ended, narrative responses to survey questions. Qualitative research methods guided analysis of the data that identified (a) the technology-supported activities and (b) the technical tools, target users, types of uses, rationales for use, and the TPACK underlying each activity. Preservice teachers described mostly teacher-focused and fewer student-focused techno-activities, and their reasoning for use focused on the technology's presentational and engagement effects. A majority of inservice teachers' techno-activities were student-focused, and their reasoning highlighted the technology's support for knowledge acquisition of higher-order cognitive skills and collaborative learning. The knowledge underlying all teachers' techno-activities was predominantly technological pedagogical knowledge (TPK), but inservice teachers also evidenced technological content knowledge (TCK). These results may reveal differences in the teachers' respective learning experiences in teacher education and professional development or reflect a professional maturation process in that it takes teachers time in the field as professionals to broaden their techno-activity repertoires to prioritize student-focus. Sharing the reasoning patterns in this study with teachers may assist them in developing deeper justifications for their technological work in the classroom.     

The impact of risk and protective factors on online teaching experience in high school Italian teachers during the COVID-19 pandemic

The lockdown due to COVID-19 in Italy resulted in the sudden closure of schools, with a shift from traditional teaching to the online one. Through an online questionnaire, this survey explores teachers' experience of online teaching, the level of risk factors (e.g., stress) and protective factors (e.g., locus of control) and their impact on satisfaction levels during the social distancing. One hundred seven high school teachers from Lombardy, an Italian region very affected by the COVID-19 outbreak, participated. Results show that depression and stress are the main predictors of satisfaction levels for online teaching. In addition, coping, locus of control and self-efficacy emerge as important protective factors. Finally, although there is great satisfaction with the online teaching experience, critical elements emerged. This study is relevant because it describes the critical elements of the online teaching experience, and identifies some protective factors and the main risk factors in teachers operating in an area strongly marked by social restrictions imposed by the pandemic. High school teachers emerge as a sub-group of the general population with specific psychological reactions. Considering the results, it is possible to suggest providing high-quality educational support and crisis-psychological oriented services to teachers, and help to maintain the psychological well-being.     

What influences geography teachers' usage of geographic information systems? A structural equation analysis

Understanding the usage of the geographic information system (GIS) among geography teachers is a crucial step in evaluating the current dissemination of GIS knowledge and skills in Taiwan's educational system. The primary contribution of this research is to further our understanding of the factors that affect teachers' GIS usage. The structural equation model was employed to analyze the data collected from 725 senior high school geography teachers. This was done using a survey questionnaire inspired by the Technology Acceptance Model (TAM), which postulates the importance of how teachers perceived the usefulness and ease of use of GIS. Further, this study investigates the direct effect of GIS workshop attendance on actual GIS usage and assesses whether GIS workshop attendance mediates the relationship between perceived ease of use, perceived usefulness, and actual usage. Structural equation modeling results suggest that the perceived usefulness of adopting GIS is vital as it directly affects teachers' attendance at GIS training, and can further prompt their application of GIS in lectures. The perceived ease of GIS use does not influence actual usage directly, but does affect teachers' GIS usage in teaching through perceived usefulness and workshop attendance. Finally, workshop attendance can increase teachers' usage of GIS and mediate the association between perceived usefulness and actual usage.     

An information security knowledge sharing model in organizations

Knowledge sharing plays an important role in the domain of information security, due to its positive effect on employees' information security awareness. It is acknowledged that security awareness is the most important factor that mitigates the risk of information security breaches in organizations. In this research, a model has been presented that shows how information security knowledge sharing (ISKS) forms and decreases the risk of information security incidents. The Motivation Theory and Theory of Planned Behavior besides Triandis model were applied as the theoretical backbone of the conceptual framework. The results of the data analysis showed that earning a reputation, and gaining promotion as an extrinsic motivation and curiosity satisfaction as an intrinsic motivation have positive effects on employees' attitude toward ISKS. However, self-worth satisfaction does not influence ISKS attitude. In addition, the findings revealed that attitude, perceived behavioral control, and subjective norms have positive effects on ISKS intention and ISKS intention affects ISKS behavior. The outcomes also showed that organizational support influences ISKS behavior more than trust. The results of this research should be of interest to academics and practitioners in the domain of information security.     

Scaffolding student teachers' information‐seeking behaviours with a network‐based tutoring system

Student teachers' instructional planning requires them to regulate certain aspects of their own learning while designing lessons. The aim of this study is to support student teachers' self‐regulated learning through the convergence effect, where network‐based tutors are designed to optimize system recommendations of online resources based on information‐seeking behaviours. A total of 68 student teachers were randomly assigned to either a dynamic or static version of nBrowser, which converged a network or not towards an optimal configuration. The structural equation model suggests that student teachers spent less time during the learning session using the dynamic version of nBrowser. Although student teachers were found to be more efficient in seeking and acquiring information and reported knowledge gains, they failed to perform better than those assigned to the static condition on the lesson plan design task. We discuss the implications for the convergence effect in the context of network‐based tutors.     

Young people,disclosure of personal information and online privacy: Control,choice and consequences

This paper examines the privacy implications of the different online practices in which young people disclose personal information, and how associated configurations of choice and control create possibilities for violations of online privacy. The implications of the commercial and non-commercial use of young peoples' personal information are examined, with a specific focus on how this can potentially facilitate cyberbullying. The paper suggests that educational strategies should more clearly focus on encouraging young people to protect their online privacy, encourage control over disclosure practices, and consider the potential commercial and non-commercial uses of their information. There is a need for development of these strategies to be informed by empirical research exploring the everyday contexts and social norms which influence young peoples' online behaviour. Such an evidence-base can inform a critical review of educational, legal and regulatory actions which aim to protect their online privacy and safety.     

Using wikis and collaborative learning for science teachers' professional development

Wiki bears great potential to transform learning and instruction by scaffolding personal and social constructivism. Past studies have shown that proper application of wiki benefits both students and teachers; however, few studies have integrated wiki and collaborative learning to examine the growth of science teachers' Technological, Pedagogical and Content Knowledge (TPACK). This study introduced a wiki‐based TPACK growth model and examined nine elementary and middle science teachers' knowledge growth in a graduate‐level course. Data sources included reflective journals, wiki data and interviews. Results showed that with wiki, science teachers learned to design more understandable and lively science teaching content, and they collaboratively generated creative instructional strategies. Furthermore, wiki and collaborative learning helped in‐service teachers exchange and elaborate ideas related to the development of TPACK. Implications, suggestions and future research directions were put forward regarding wiki, TPACK and in‐service teachers' professional development.
