Contact Tracing for Misinformation

Since January 2020, COVID-19 has been the main topic of news. Despite attempts to keep health information accurate, misinformation has been put out from amateur and speculative sources all the way up to President Trump.

Facebook has been blamed along with other social media sites for allowing misinformation to spread. himself. Many websites from traditional media to social media have been trying to connect people to accurate information from health experts and keep harmful misinformation from spreading. It is a difficult task, even with the best technology, to monitor millions of users creating content every second and even more often reposting other information.

Facebook has said that they have directed over 2 billion people to resources from the World Health Organization in their "COVID-19 Information Center" and via pop-ups on Facebook and Instagram with over 350 million people clicking through to learn more.

When a piece of content is rated false by fact-checkers, they reduce its distribution and show warning labels with more context, and they can use similarity detection methods to identify duplicates of debunked stories. 

I heard on an episode of the Make Me Smart podcast that Rep. Adam Schiff (not a Facebook fan) asked other tech giants (Google, YouTube, Twitter) to follow Facebook's example by contacting users who’ve interacted with misinformation. 

This is a kind of contact tracing for misinformation. In public health contact tracing, staff work with a patient to help them recall everyone with whom they have had close contact during the timeframe while they may have been infectious. The public health staff then warn these exposed individuals (contacts) of their potential exposure as rapidly and sensitively as possible.

In public health or online protecting patient/poster and contacts is important. Generally in health situations contacts are only informed that they may have been exposed to a patient with the infection but are not told the identity of the person who may have exposed them.

YouTube announced it would add informational panels with information from its fact-checkers to videos in the US, an expansion of a program it launched in India and Brazil last year.

Twitter introduced its COVID-19 content policies earlier this month, which require users to remove tweets with content that includes misinformation about coronavirus treatments or misleading content meant to look like it’s from authorities and recently updated their policy to encompass tweets that may “incite people to action and cause widespread panic, social unrest or large-scale disorder,” such as burning 5G towers.

Apps in Education 2011 to 2020

In 2011, I made presentations at several colleges about the use of mobile apps in education and teaching in an "app world." At that time, apps were a big topic in the tech world but not a big topic in education. That presentation (it is on my Slideshare site) included the slide below where education doesn't even appear as a category unless you consider it to be part of the 5% of "other" app consumption. Clearly, games and social networking dominated usage at that time and they both still garner a high percentage of app use.

How we were using apps in 2011

Showing this slide to college faculty reinforced their idea that apps are not for education. Of course, in 2011 apps were also not for common banking and financial use, medical records, and other "serious" computing.

That has certainly changed. But has it changed for education?

Reviewing my own 2011 presentation predictions, I said that I thought apps would come to education in three waves: Adoption, Adaption, and Creation.

Adoption was schools and educators adopting existing apps that had some education features or were designed for education. The obvious one then and now was apps for learning management systems. Blackboard was the first I used but now Canvas and all the other players have them. Adoption was not immediate. The two colleges I worked at then both chose not to offer the mobile version. Faculty could not see how you could possibly take a course on your phone. But I had a graduate student that year who told me that she did her coursework for me on her phone in her free time while she was at her night job. We were using Moodle and she just resized the web pages. I couldn't see how that worked but I knew an app would have made it better.

The second wave was adaption - using apps not specifically designed for education in courses. That was being done by individual teachers as they discovered and bought into the app world. Adaption requires some pedagogical changes. Mobile devices still were not acceptable (even banned) in some classrooms in 2011. It was the rare faculty member who said "Take out your phone..." and asked students to use it for class. 

Now in this time of the pandemic, it is clear to schools, teachers, students, and parents how "educational" phones or tablets can be. Schools are supplying tablets the way we once supplied laptops. But even laptops are using apps. I'm sure app downloads are up in the past two months. App versions of Zoom and others have become common tools not only for educators but or personal use.

That move from personal to professional (business or education) use is critical to adoption or adaption/adaptation. As teachers started using their phones and apps more in their everyday screen time, the move to use them for teaching became easier.
 

apps in education

Something that made faculty fearful in 2011

Those 2011 audiences weren't sold on using apps in the first half of my presentation. They weren't using apps for themselves. Some did not have a smartphone. But they were hearing "There's an app for that" from friends, colleagues their students and on television commercials. They knew it was coming.

I caught their interest when I shifted to talking about why - even though I was an app evangelist - apps are NOT online courses or would virtual schools in the near future. (I find that educators generally like the status quo.) There was an article I pointed to that was headlined “My Teacher Is An App.” A provocative headline but the article did follow my point that things were changing but we wouldn't be there for quite a while.

The article said “In a radical rethinking of what it means to go to school, states and districts nationwide are launching online public schools that let students from kindergarten to 12th grade take some—or all—of their classes from their bedrooms, living rooms, and kitchens. Other states and districts are bringing students into brick-and-mortar schools for instruction that is largely computer-based and self-directed.”

That was not common in 2011 and still wasn't common in 2019 - but it is a lot closer to being true in the spring of 2020.

I wondered then if apps would be driving curriculum or would curriculum be driving app development. I'm pleased that the latter seems to be generally the case now.

I asked the audience if they believed that this reliance on smartphones and apps will "produce forgetfulness in the minds of those who learn to use it because they will not practice their memory. You have invented an elixir not of memory, but of reminding; and you offer your pupils the appearance of wisdom, not true wisdom, for they will read many Socrates on the things without instruction and written word, will, therefore, seem to know many things, when they are for the most part ignorant and hard to get along with since they are not wise but only appear wise.”

Those in the audience who did agree were right in line with Socrates in 340 BC since those were his words on his belief about the dangers of the written word. Socrates was wrong about the adoption of the written word into education.

My third wave was just beginning to form in 2011. That was colleges creating their own apps. I had a few examples of colleges adopting and adapting things like parking and events using commercial apps and GPS to navigate campuses or scheduling apps for campus calendars, courses, or facilities scheduling.

But do schools need to create their own apps or just purchase commercial ones that can be branded? I looked back to the development of school websites as an example. Initially, most schools bought a package or a vendor but along the way many schools took it on as an in-house operation, perhaps using some commercial products - a combination of creation and adaptation. 

In 2011, may school websites weren't even dynamic enough ready for viewing on phones or tablets. But schools were creating their own apps and courses about how to develop apps were becoming a hot topic.

In 2020, there are plenty of no-code tools for app development (Airtable, Bubble, Zapier, Coda, Webflow) so that it doesn't take a wizard developer to make a fully functioning app. 

If you are a teacher or student at any level K-20, the chances are excellent that you are using apps in your courses and on your campus.

Should the Class Lecture Be Saved?

Last semester in the Chronicle of Higher Education there was an article that asked, "Can The Lecture Be Saved?" This semester in the midst of shuttered campuses there has been far fewer traditional lectures. By "traditional" I mean the long ones you might have sat through in a 90-minute class or the dreaded 3-hour graduate class.

In general, I think lecture times have decreased in the past 20 years. Building online courses during those years, I have always strongly encouraged faculty to chunk their traditional lectures into shorter mini-lectures. Student attention spans have decreased, perhaps partially because they are used to videos online from YouTube stars to Khan Academy being 20 minutes or less.

Faculty have also been told that lecturing is bad. Educators have gone through "flipping the classroom" and “active learning” and have been told that they should not be the "sage on the stage" but rather the "guide on the side." Still, a lecture can transmit the knowledge level that even Bloom knew was necessary for learning. He believed that knowledge “involves the recall of specifics and universals, the recall of methods and processes, or the recall of a pattern, structure, or setting.” A lecture is one way to deliver that.

That Chronicle article says that faculty should not feel guilty about doing some lecturing., but the secret is to make it interactive. Part of that means that instructors break up their lectures with other activities that reinforce what students learn through the lecture, and also encourage them to apply it. A term used is "interactive lecturing."

In my discussions the past two months with teachers in high schools and colleges, the sense I get is that their online classes are very much not lecture-based. When they do present content via video (and for some just audio) it is shorter than a "lecture" and less formal. 

The article focuses on how Claire Major, a professor of higher education administration at the University of Alabama, arrived at her own teaching style. Some of what she recommends is on this interactive lecturing quick reference chart (pdf).

The structure she tries to use for each class is a good, simple instructional design to consider online or in a physical classroom.

She includes "bookends" to begin and end class. I liked using a 5-minute writing task at the very start of class (sometimes as students entered the room). I learned this many years ago as the "anticipatory set" of the lesson. It might be a question to gauge their knowledge of one of the session's topics or it could be to be at Bloom's comprehension level by asking them to explain, summarize, paraphrase, illustrate to any other action to show that they can comprehend or interpret information based on prior learning.

Major's "overlays" are used to encourage students to pay attention during the lecture portion of the class. Like her, I sometimes used cloze activities (AKA guided notes) that could be completed by listening to the lecture. I knew them from my K12 teaching and brought them to a number of college teachers as a way to check comprehension as a self-check for students or for me to check their comprehension.

Similarly, her "interleaves" are activities during class to help students apply what they just learned. The "think-pair-share" exercise is hardly new to most teachers. Hands-on activities and group work easier in a physical classroom than online. But online you need to structure activities to be completed by students before allowing them to continue with a lesson. Most learning management systems and some screen capture and video programs have tools to include checks for comprehension points in a lesson.

Should the lecture be saved? Yes, saved for when necessary, and redefined.  

 

The Post-Pandemic Campus

empty classroomAn article in The Chronicle of Higher Education (unfortunately, "premium" for subscribers even in these pandemic days) is called "How Should Colleges Prepare for a Post-Pandemic World?" by Brian Rosenberg. His general advice is to "anticipate and plan for change rather than merely hope that it will not arrive." Change has arrived.

This article may be for higher education but almost all of these thoughts apply to K12 schools too.

Here are my highlighted excerpts with some commentary:

  • College is staggeringly expensive. Students and their families are going to be hard hit. Plus, colleges that have lost enormous sums of money will be attempting to recap but from families that have lost income and savings: Most colleges will need to provide more financial aid and possibly fewer services with fewer people.
  • When the lockdown is over there will still be a period of voluntary separation. With no vaccine, many people are still going to be hesitant to travel, return to campus, interact in groups in classrooms and labs. I suspect there will be more gap years than in the past.
  • Distance learning was forced upon us. Some of it was fine. It had been fine in many courses before all this. Some of it was lacking. It was done in a panic without much time to prepare and with faculty and students were not ready for it and never wanted to be online before. Schools need to really evaluate what worked, what didn't work and what they will change next time this kind of longterm disruption occurs. And it will.
    What courses and subjects can use the online model to be less expensive but still highly effective? Of course, most schools still charge the same for an online course as a face-to-face one, so there is no savings for students.  way to teach. Can a hybrid model of in-person+online lower cost? These are not new questions to ask, but too many schools have still never addressed them - and the answers may be different in 20121 than they were in 2019. 
  • Is distance learning "good enough" in a world of sharply diminished resources? The author suspects that for many students and families the answer will be yes. I agree.
  • So, how should schools prepare for the post-pandemic world? It is better to anticipate and plan for change than merely to hope that it will not arrive. One change might be rethinking the traditional academic calendar - "which is almost unique in its inefficiency."  The author suggests the "simplest way to lower the cost of college" but it is not the easiest way - eliminate the long breaks and make it easier for students to graduate in three years.
