Searching for "screen"
Dear colleagues,
I am collaborating on a project comparing the efficacy of two types of instructional videos. We are looking for literature that describes similar research. For example, a study might compare students who have watched voice-over ppt slides and students who have watched Khan-style videos, examining students’ content knowledge and/or some affective constructs. Alternatively, a study might compare the lengths or speeds of only one type of video.
Given the dearth of literature addressing these variables, I am hoping this community can help us uncover some additional research for our literature review. I am happy to compile and share everything that is shared with me over the coming days.

It is impossible to please everyone all the time—at least that is what survey results suggest. There are several takeaways to this study: Video length matters, especially as a consideration before the video is viewed. Timestamps should be included in video creation, or it is highly likely that the video will not be viewed. The video player is key here, as some video players include video length, while others do not. Videos that exceed four minutes are unlikely to be viewed unless they are required. Voice quality in narration matters. Although preference in type of voice inevitably varies, the actor’s voice is noticed over production value. It is important that the narrator speaks evenly and clearly. For brief how-to videos, there is a small preference for screencast instructional videos over a narrative roleplay scenario. The results of the survey indicate that roleplay videos should be wellproduced, brief, and high quality. However, what constitutes high quality is not very well established.15 Finally, screencast videos should include an example scenario, however brief, to ground the viewer in the task.

Blockchain: Recommendations for the Information Profession
Monday, September 24, 2018 12:00 pm
Central Daylight Time (Chicago, GMT-05:00)
Blockchain technology is being discussed widely, but without clear directions for library applications. The Blockchain National Forum, funded by IMLS and held at San Jose State University’s iSchool in Summer 2018, brought together notable experts in the information professions, business, government, and urban planning to discuss the issues and develop recommendations on the future uses of blockchain technology within the information professions. In this free webinar, Drs. Sandy Hirsh and Sue Alman, co-PIs of the project, will present the recommendations made throughout the year in the Blockchain blog, Library 2.0 Conference, Blockchain Applied: Impact on the Information Profession, and the National Forum.
157 – 200 participants in the workshop

Is Blockchain (BC) content or provider?
Q/S TO ASK: WHAT KINDS OF DATA AND RECORDS MUST BE STORED AND PRESERVES exactly the way they were created (provenance records, transcripts). what kinds of info are at risk to be altered and compromised by changing circumstances (personally identifiable data)
Security issues: https://www.technologyreview.com/magazine/2018/05/
515 rule: BC can be hacked if attacked by a group of miners controlling more than 50% of the network
Standards Issues: BC systems- open ledger technology for managing metadata. baseline standards will impact future options. can BC make management of metadata worth. Is it worth, or more cautious.
Potential Use cases: archives and special collections where provenance and authenticity are essential for authoritative tracking. digital preservation to track distributed digital assets. BC-based currencies for international financial transactions (to avoid exchange rates ILL and publishing) . potential to improve ownership and first sale record management. credentialing: personal & academic documents (MIT already has transcripts and diplomas of students in BC – personal data management and credentialing electronically).
public libraries: house docs of temporarily displaced or immigrants. but power usage and storage usage became problems.

How Data Privacy Lessons in Alternative Reality Games Can Help Kids In Real Life
https://www.kqed.org/mindshift/51772/how-data-privacy-lessons-in-alternative-reality-games-can-help-kids-in-real-life
Ubiquitous social media platforms—including Facebook, Twitter and Instagram—have created a venue for people to share and connect with others. We use these services by clicking “I Agree” on Terms of Service screens, trading off some of our private and personal data for seemingly free services. While these services say data collection helps create a better user experience, that data is also potentially exploitable.
The news about how third parties obtain and use Facebook users’ data to wage political campaigns and the mounting evidence of election interference have shined a spotlight on just how secure our data is when we share online. Educating youth about data security can fall under the larger umbrella of digital citizenship, such as social media uses and misuses and learning how not to embarrass or endanger oneself while using the internet.
Darvasi’s students in Toronto can pool together 55 faux bitcoins to purchase and launch the BOTTING protocol against an opponent. The student targeted at Fallon’s school in Connecticut would then have 48 hours to record audio of 10 words of Darvasi’s students choosing and send it back to them through an intermediary (Darvasi or Fallon). For a higher price of 65 faux bitcoins, students can launch MORPHLING, which would give the opponent 48 hours to record a one-minute video explaining three ways to stay safe while using Facebook, while making their school mascot (or a close approximation of) appear in the video in some way during the entire minute.

Digital Text is Changing How Kids Read—Just Not in the Way That You Think
https://www.kqed.org/mindshift/49092/digital-text-is-changing-how-kids-read-just-not-in-the-way-that-you-think
According to San Jose State University researcher Ziming Lu, this is typical “screen-based reading behavior,” with more time spent browsing, scanning and skimming than in-depth reading. As reading experiences move online, experts have been exploring how reading from a screen may be changing our brains. Reading expert Maryanne Wolf, author of Proust and the Squid, has voiced concerns that digital reading will negatively affect the brain’s ability to read deeply for sophisticated understanding, something that Nicholas Carr also explored in his book, The Shallows. Teachers are trying to steer students toward digital reading strategies that practice deep reading, and nine out of ten parents say that having their children read paper books is important to them.
Cognitive scientist Daniel T. Willingham said that digital devices aren’t changing the way kids read in terms of actual cognitive processes—putting together letters to make words, and words to make sentences. In fact, Willingham is quick to point out that in terms of “raw words,” kids are reading more now than they were a decade ago (thanks mostly to text messaging). But he does believe, as he writes in his book, The Reading Mind: A Cognitive Approach to Understanding How the Mind Reads, that kids’ reading habits are changing. And it’s reasonable to guess that digital technology, in all its three-second-video and Snapchat glory, is changing those habits.
For many parents and teachers worried that spending so much time with video games and Snapchats will shred kids’ attention spans—the average 8-12-year-old spends about six hours a day in front of a screen, and teenagers spend more than nine — Willingham thinks they may be concerned about the wrong thing. He isn’t convinced that spending so many hours playing Super Smash Bros will shorten kids’ attention spans, making them unable to sustain the attention to read a book. He’s more concerned that Super Smash Bros has trained kids’ brains to crave experiences that are more like fast-paced video games.
instead to help kids distinguish between the easy pleasures of some digital media, and the more complex payoff that comes when reaching the end of the Harry Potter series. He recommends telling kids that you want them to experience both, part of a larger strategy to make reading a family value.
“It’s watermelon or chocolate for dessert.
According to Julie Coiro, a reading researcher at the University of Rhode Island, moving from digital to paper and back again is only a piece of the attention puzzle: the larger and more pressing issue is how reading online is taxing kids’ attention.
Each time a student reads online content, Coiro said, they are faced with almost limitless input and decisions, including images, video and multiple hyperlinks that lead to even more information.
Teens worry they use phones too much

Roughly half of U.S. teens say they spend too much time on their cellphones, according to research from Pew. About the same proportion of teens report taking steps to limit their use of the devices. Another survey found that about two-thirds of parents also worry their children spend too much time in front of screens; nearly 60% of parents report setting screen time restrictions for their children. The findings come as some technology companies introduce features to cut back on phone addiction.

http://www.pewinternet.org/2018/08/22/how-teens-and-parents-navigate-screen-time-and-device-distractions/
Amid roiling debates about the impact of screen time on teenagers, roughly half of those ages 13 to 17 are themselves worried they spend too much time on their cellphones. Some 52% of U.S. teens report taking steps to cut back on their mobile phone use, and similar shares have tried to limit their use of social media (57%) or video games (58%), a new Pew Research Center survey finds.
Overall, 56% of teens associate the absence of their cellphone with at least one of these three emotions: loneliness, being upset or feeling anxious. Additionally, girls are more likely than boys to feel anxious or lonely without their cellphone.
The vast majority of teens in the United States have access to a smartphone, and 45% are online on a near constant basis. The ubiquity of social media and cellphones and other devices in teens’ lives has fueled heated discussions over the effects of excessive screen time and parents’ role in limiting teens’ screen exposure. In recent months, many major technology companies, including Google and Apple, have announced new products aimed at helping adults and teens monitor and manage their online usage.
Girls are somewhat more likely than boys to say they spend too much time on social media (47% vs. 35%).
Meanwhile, 31% of teens say they lose focus in class because they are checking their cellphone – though just 8% say this often happens to them, and 38% say it never does.
Girls are more likely than boys to express feelings of anxiety (by a 49% to 35% margin) and loneliness (by a 32% to 20% margin) when they do not have their phone with them.

Addressing mental health issues critical to boosting academic success
Autumn A. Arnett,Aug. 8, 2018 https://www.educationdive.com/news/addressing-mental-health-issues-critical-to-boosting-academic-success/529381/,
It is estimated that 13% to 20% of children living in the United States has experienced a mental health disorder in the last year. According to the National Alliance of Mental Illness, one in five adolescents between 13 and 18 years old has or will have a serious mental illness, and suicide is the third leading cause of death for youth aged 10 to 24.
A nationwide shortage of school psychologists and counselors disproportionately affects these students as well, as they often attend more crowded, under-resourced schools, though they have the greatest need.
Some districts and universities are working to train staff to identify and, in some cases, assist students with mental illness on campus. Teachers21, a nonprofit subsidiary of William James College, a graduate college of psychology in Newton, Massachusetts, is working with classroom, school and district leaders and other school staff to build mental health treatment into their pedagogy. Trauma-informed teaching has become a popular concept, feeding into the idea of restorative justice
Most of these efforts — and a focus on social-emotional learning in general — are concentrated in elementary schools, and by the time a student reaches middle school, the emphasis begins to fizzle out. And by the time a student gets onto a college campus, efforts are all but non-existent, said Williams James President Nicholas Covino, who is a practicing psychologist.

Report calls for national strategy to help schools prevent suicide, substance abuse
https://www.educationdive.com/news/report-calls-for-national-strategy-to-help-schools-prevent-suicide-substan/529915/
Amelia Harper Aug. 13, 2018
- The Trust for America’s Health and the Well Being Trust created a joint policy paper that calls for a national strategy to improve childhood resilience and school responses to crises involving suicide, drugs and alcohol, District Administration reports.
- The issue is relevant to schools, where students spend about half their year, because suicide is now the third leading cause of death in children ages 10 to 14, and more than 1 million middle school and high school age students have a substance abuse disorder, the authors note.
- The policy paper details four main areas of concern that need to be addressed on the school level: the need to partner with community-based organizations, such as Communities that Care; the need to improve school climate through such programs as Positive Behavioral Interventions and Supports (PBIS); the need for proactive screening for mental health risk factors and potential substance abuse; and increased staffing of mental health workers and training of teachers.
