TL;DR: In this study a survey was done to investigate students’ use of media, as well as the behavioural beliefs, norms and motivators surrounding such use.
Abstract: The growing presence of digital media in the lives of university students signals a change in how use of such media in educational contexts should be viewed. Institutional focus on technologically mediated education and the promotion of blended learning initiatives further serve to encourage media use in academic settings. Scant attention has been afforded to the potential negative consequences arising from heightened media engagement. This is especially the case in areas of study where technological artifacts are often the medium and the subject of interest, for instance the computer and information sciences. In this study a survey was done to investigate students’ use of media, as well as the behavioural beliefs, norms and motivators surrounding such use.

TL;DR: It is proposed that the constant distractions created by digital media, interrupt the thought and communication processes of students during lectures and, subsequently, obstruct their ability to learn.
Abstract: The growing prevalence of continuous media use among university students in lecture environments has potential for detrimental effects. In this study we investigate the relationships between in-lecture media use and academic performance. Previous studies have shown that students frequently engage with digital media whilst in university lectures. Moreover, multitasking imposes cognitive costs detrimental to learning and task execution. We propose, accordingly, that the constant distractions created by digital media, interrupt the thought and communication processes of students during lectures and, subsequently, obstruct their ability to learn. To test this proposition we conducted a survey-based empirical investigation of digital media use and academic performance among undergraduate university students. A significant negative correlation was found between the number of in-lecture media use instances and academic performance. Furthermore, this effect was found to be pervasive independent of individual demographic factors and the intention with which a medium was used.

TL;DR: A survey-based empirical investigation of digital media use and academic performance among undergraduate university students confirmed the hypothesis that there exists a negative correlation betweendigital media use during lectures and academics performance.
Abstract: The growing prevalence of continuous media use among university students in lecture environments has potential for detrimental effects. In this study the focus is placed upon the implications of digital media multitasking in a university lecture context for academic performance and learning. Previous studies reveal that students frequently engage with digital media whilst in a university lecture. Moreover, research has shown that multitasking imposes a cognitive cost, detrimental to learning and task execution. We propose, accordingly, that the constant distractions created by digital media interrupt the thought and communication processes of students and, subsequently, obstruct their ability to learn. To test this proposition we conduct a survey-based empirical investigation of digital media use and academic performance among undergraduate university students. A clear negative correlation was shown between frequency of media use and academic performance. This result confirms the hypothesis that there exists a negative correlation between digital media use during lectures and academic performance. The confirmation of this negative relationship suggests that media use poses a significant distraction to students.

TL;DR: The World is Flat: A Brief History of the Twenty-First Century Thomas L. Friedman Farrar, Straus and Giroux, 2005 Thomas Friedman is a widely-acclaimed journalist, foreign affairs columnist for the New York Times, and author of four best-selling books that include From Beirut to Jerusalem (1989) as mentioned in this paper.
Abstract: The World is Flat: A Brief History of the Twenty-First Century Thomas L. Friedman Farrar, Straus and Giroux, 2005 Thomas Friedman is a widely-acclaimed journalist, foreign affairs columnist for the New York Times, and author of four best-selling books that include From Beirut to Jerusalem (1989). His eminence as a journalist is clearly demonstrated in the way he prepared for The World is Flat. He traveled throughout the world, interviewing in depth the political and business leaders who have the most direct, hands-on knowledge of the truly incredible developments occurring in the business structures and technology of globalization. Only a journalist who moves freely at the highest levels could interview the likes of Sir John Rose, the chief executive of Rolls-Royce; Nobuyuki Idei, the chairman of Sony; Richard Koo, the chief economist for the Nomura Research Institute; Bill Gates of Microsoft; Wee Theng Tan, the president of Intel China; David Baltimore, president of Caltech; Howard Schultz, founder and chairman of Starbucks; Nandan Nilekani, CEO of Infosys in Bangalore - and many others, each of whom gave him the inside story of how, specifically, the barriers of time and space separating economies, workforces, sources of capital, and technical abilities are crumbling. The result of this unfolding story, already far along but with much farther to go, according to Friedman, is that "the world is flat." With some notable exceptions in sub-Saharan Africa and the Islamic swathe, everything is connected with everything else on a horizontal basis, with distance and erstwhile time-lags no longer mattering. Friedman describes in detail the galloping globalization that has unfolded in even so limited a time as the past five years. Under the impetus of a worldwide network of interconnectivity, the world economy is much-changed from what it was at the turn of the century a mere half-decade ago. Friedman quotes the CEO of India's Infosys: "What happened over the last [few] years is that there was a massive investment in technology, especially in the bubble era, when hundreds of millions of dollars were invested in putting broadband connectivity around the world, undersea cables," while (Friedman paraphrases him) "computers became cheaper and dispersed all over the world, and there was an explosion of software - e-mail, search engines like Google, and proprietary software that can chop up any piece of work and send one part to Boston, one part to Bangalore, and one part to Beijing...." Microprocessors today have 410 million transistors compared to the 2800 they had in 1971. And now, "wireless is what will allow you to take everything that has been digitized, made virtual and personal, and do it from anywhere." The effect on productivity is revolutionary: "It now takes Boeing eleven days to build a 737, down from twenty-eight days just a few years ago. Boeing will build the next generation of planes in three days, because all the parts are computer-designed for assembly." The most strikingly informative aspect of this book, however, is not about technology. Most especially, Friedman explores the rapidly evolving global business systems, each constantly regenerating itself to keep ahead of the others. These are systems that span the continents seeking the lowest-cost providers of everything from expert scientific and engineering work to the lowliest grunt work. Friedman points out that India produces 70,000 accounting graduates each year - and that they are willing to start at $100 a month. It is no wonder that Boeing employs 800 Russian scientists and engineers for passenger-plane design when "a U.S. aeronautical engineer costs $120 per design hour, a Russian costs about one-third of that." Friedman describes a call center in India where outbound callers sell "everything from credit cards to phone minutes," while operators taking inbound calls do "everything from tracing lost luggage for U.S. and European airline passengers to solving computer problems for confused American consumers. …

TL;DR: In this paper, Meyrowitz shows how changes in media have created new social situations that are no longer shaped by where we are or who is "with" us, making it impossible for us to behave with each other in traditional ways.
Abstract: How have changes in media affected our everyday experience, behavior, and sense of identity? Such questions have generated endless arguments and speculations, but no thinker has addressed the issue with such force and originality as Joshua Meyrowitz in No Sense of Place. Advancing a daring and sophisticated theory, Meyrowitz shows how television and other electronic media have created new social situations that are no longer shaped by where we are or who is "with" us. While other media experts have limited the debate to message content, Meyrowitz focuses on the ways in which changes in media rearrange "who knows what about whom" and "who knows what compared to whom," making it impossible for us to behave with each other in traditional ways. No Sense of Place explains how the electronic landscape has encouraged the development of: -More adultlike children and more childlike adults; -More career-oriented women and more family-oriented men; and -Leaders who try to act more like the "person next door" and real neighbors who want to have a greater say in local, national, and international affairs. The dramatic changes fostered by electronic media, notes Meyrowitz, are neither entirely good nor entirely bad. In some ways, we are returning to older, pre-literate forms of social behavior, becoming "hunters and gatherers of an information age." In other ways, we are rushing forward into a new social world. New media have helped to liberate many people from restrictive, place-defined roles, but the resulting heightened expectations have also led to new social tensions and frustrations. Once taken-for-granted behaviors are now subject to constant debate and negotiation. The book richly explicates the quadruple pun in its title: Changes in media transform how we sense information and how we make sense of our physical and social places in the world.

TL;DR: In this paper, the authors performed a focalized investigation on revealing the relationship between positive and negative characteristics of social media and the learning attitude of university students for sustainable education, and they applied the social gratification theory to examine students' behavior practicing social media usage.
Abstract: In today’s world, social media is playing an indispensable role on the learning behavior of university students to achieve sustainable education. The impact of social media on sustainable education is becoming an essential and impelling factor. The world has become a global village and technology use has made it a smaller world through social media and how it is changing instruction. This original study is amongst the few to perform a focalized investigation on revealing the relationship between positive and negative characteristics of social media and the learning attitude of university students for sustainable education. However, this study aims to examine the constructive and adverse factors that impact on students’ minds and how these helped students to share positive and negative aspects with others. It is increasingly noticeable that social networking sites and their applications present enormous benefits for as well as risks to university students and their implications on students’ psychological adjustment or learning behaviors are not well understood. This study adapted the cluster sampling method, and respondents participated from five selected regions. Researchers distributed 1013 questionnaires among the targeted sample of university students with an age range of 16 to 35 years, and they collected 831 complete/valid responses. This study applied the social gratification theory to examine students’ behavior practicing social media usage. This study specifically identified 18 adversarial and constructive factors of social media from the previous literature. The findings revealed that the usage of social media in Pakistan has a negative influence on a student’s behavior as compared to positive aspects. Results may not be generalized to the entire student community as findings are specific to the specific respondents only. This study presents a relationship between antithetical and creative characteristics of social media and exhibits avenues for future studies by facilitating a better understanding of web-based social network use.

TL;DR: The authors conducted a meta-analysis of self-reported and log-based measures of media use and found that selfreported media use correlates only moderately with logged measurements, that self-reports were rarely an accurate reflection of logged media use, and that problematic media use showed an even weaker association with usage logs.
Abstract: There is widespread public and academic interest in understanding the uses and effects of digital media. Scholars primarily use self-report measures of the quantity or duration of media use as proxies for more objective measures, but the validity of these self-reports remains unclear. Advancements in data collection techniques have produced a collection of studies indexing both self-reported and log-based measures. To assess the alignment between these measures, we conducted a pre-registered meta-analysis of this research. Based on 106 effect sizes, we found that self-reported media use correlates only moderately with logged measurements, that self-reports were rarely an accurate reflection of logged media use and that measures of problematic media use show an even weaker association with usage logs. These findings raise concerns about the validity of findings relying solely on self-reported measures of media use. In a pre-registered meta-analysis, Parry et al. find that, when self-reported media use is compared with digital logs of media use, subjective judgements are often inaccurate. This suggests caution when self-reports are used to test associations between media use and other outcomes.
