To reach a global audience, think smaller – screens, i.e.

WEST LAFAYETTE, Ind. – Scientists around the world are developing new technologies and information that can improve the lives of people in developing countries. However, putting this knowledge in their hands is often difficult.

One thing communicators can do, according to research from Purdue University and Michigan State University, is focus on smaller screens.

Barry pittendrigh, the Purdue Osmun Endowed Chair in an Urban Setting Entomology and director of the Urban and industrial pest control center, and Julia Bello-Bravo, an assistant professor in the Department of Food Sciences and Human Nutrition at Michigan State University, analyzed data from Scientific Animations Without Borders (SAWBO). SAWBO is a university program they co-founded that develops and distributes educational events on topics such as agriculture, health and women’s empowerment. They report in the newspaper helion that from July 2015 to August 2018, the majority of designated educational video viewers in developing countries consumed this content through mobile devices, surpassing desktop computers.

To date, SAWBO has produced over 110 thematic videos in over 230 languages ​​and dialects which have been viewed over 10 million times by people on Youtube. Countless other people have viewed the documents via shared videos, and over 40 million people have viewed them as broadcasts on TV stations in Africa and Asia.

“The sheer volume of YouTube data collected on the SAWBO channel in well over 100 countries has made us ask the question, ‘When did cellphones overtake computers as a means of delivering our educational content? Said Bello-Bravo, who is joining Purdue Department of Agricultural Sciences Education and Communication this autumn. “If we think of other technologies, such as printing, radio, television and the Internet, there was a time when they became a major force in the way people accessed knowledge. With our dataset at hand, we could ask this question on cellphones and identify the tipping point both globally and by region of the world. “

SAWBO data shows that mobile devices have become the dominant method of viewing SAWBO’s YouTube videos in all regions of the world, with the global average being in mid-2016. The trend started in Asia, followed by America. Central, North America, South America, Africa then Europe.

This analysis documents a historic change in cell phone use, but it also has practical implications.

“In developing countries it is much easier and cheaper to buy a cell phone than a desktop or laptop computer, and the cost of cell phones has fallen in recent years,” Bello-Bravo said. . “This shift in the way people access such educational content can inform the way we communicate with people around the world.”

As mobile technology becomes mainstream and grows in popularity, Pittendrigh said, communicators should consider screen size, letter size, and image sharpness when developing videos and animations for have the most impactful messages.

“Basically for the development community, you will have to look to applicable content on mobile phones, as we have reached the tipping point where these technologies have gone from the promise of being an important mechanism for delivering content to becoming dominant. “Said Pittendrigh.” The distribution of linguistically adaptable educational videos is important for people who speak a variety of languages, are low-literate learners, or both. Access to the knowledge contained in such videos has the potential to ‘improve lives, from better farming practices to better health. “

Bello-Bravo and Pittendrigh hope that individuals and organizations with a mission to serve these populations can use the results to reach more people with critical knowledge.

“What were once areas and populations that were inaccessible due to infrastructure and personnel restrictions have now become accessible due to the ubiquity of mobile technology,” they wrote to Heliyon. “Governments and international development organizations would do well to take this change into account and adjust their strategies accordingly. “

Bello-Bravo and Pittendrigh co-authored the article with Anne Lutomia of Purdue, postdoctoral researcher, John Medendorp, associate director of the Urban and industrial pest control center, Ian Brooks, director of the Center for Health Informatics, a World Health Organization collaborating center on health information systems, at the University of Illinois at Urbana-Champaign, and Jeremy Bohonos at the Texas State University.

Despite extensive research on YouTube as a digital media platform, little research to date has quantified the type of device used to access than online media. Analyze data from access devices for videos on a YouTube video channel — Scientific Animations Without Borders (SAWBO), which produces educational content specifically accessible to low and non-literate, poor or geographically isolated learners in less developed regions of the world —The results identify historic moments between 2015 and 2017 when mobile phones / smartphones, both globally and by region, crossed a tipping point to overtake all other ICT devices (including desktops, laptops and other internet access technologies) as the primary type of device for accessing SAWBO videos. Specifically, data from January 2013 to June 2018 obtained for SAWBO’s YouTube channel was sampled to capture and distinguish the type of access device used, then summarized into broad global and regional categories. The tipping point, as the date when the percentage of views from cellphones was equivalent to the percentage of views from computers, was also calculated globally and by region. In addition to documenting this critical global historic moment, the findings also have implications for mass digital messaging in general and mobile-based public service learning in particular.
