Digital Media Has a Misinformation Problem—but It’s an Opportunity for Teaching.
Jennifer Sparrow Dec 13, 2018
Research has shown that 50 percent of college students spend a minimum of five hours each week on social media. These social channels feed information from news outlets, private bloggers, friends and family, and myriad other sources that are often curated based on the user’s interests. But what really makes social media a tricky resource for students and educators alike is that most companies don’t view themselves as content publishers. This position essentially absolves social media platforms of the responsibility to monitor what their users share, and that can allow false even harmful information to circulate.
“How do we help students become better consumers of information, data, and communication?” Fluency in each of these areas is integral to 21st century-citizenry, for which we must prepare students.
In English 202C, a technical writing course, students use our Invention Studio and littleBits to practice inventing their own electronic devices, write instructions for how to construct the device, and have classmates reproduce the invention.
The proliferation of mobile devices and high-speed Wi-Fi have made videos a common outlet for information-sharing. To keep up with the changing means of communication, Penn State campuses are equipped with One Button Studio, where students can learn to produce professional-quality video. With this, students must learn how to take information and translate it into a visual medium in a way that will best benefit the intended audience. They can also use the studios to hone their presentation or interview skills by recording practice sessions and then reviewing the footage.

Released on Friday, the Zao app went viral as Chinese users seized on the chance to see themselves act out scenes from well-known movies using deepfake technology, which has already prompted concerns elsewhere over potential misuse.
As of Monday afternoon it remained the top free download in China, according to the app market data provider App Annie.
Concerns over deepfakes have grown since the 2016 US election campaign, which saw wide use of online misinformation, according to US investigations.
In June, Facebook’s chief executive, Mark Zuckerberg, said the social network was struggling to find ways to deal with deepfake videos, saying they may constitute “a completely different category” of misinformation than anything faced before.

Wi-Fi 6, the consumer-friendly new name for the tech standard actually called 802.11ax,
wireless chip designer Qualcomm is betting big on Wi-Fi 6
“Cord cutting is real. What was typically one TV in the average home is now five or six different screens,” Patel said. “There’s a tremendous amount of content sourced through the home that wasn’t before. There’s a congestion problem.”
One of Wi-Fi 6’s biggest advances is OFDMA — orthogonal frequency division multiple access, if you must know — an efficiency-boosting technology purloined from mobile networks. Another is MU MIMO, short for multiple user, multiple input, multiple output. And then there’s 1024 QAM — quadrature amplitude modulation — which bumps up data rates by 30%.
- Double the range — though Qualcomm has built-in mesh networking technology that’ll let multiple wireless access points cooperate to bathe your house in Wi-Fi radio signals.
- Triple the speed — useful not just for watching 4K video but also for uploading from our phones.
- Better reliability — good for avoiding video chats plagued by stuttering.
Qualcomm President Cristiano Amon says Wi-Fi 6 and 5G networks complement each other.

Developed by Dr. Ruben Puentedura, the SAMR Model aims to guide teachers in integrating technology into their classrooms. It consists of four steps: Substitution (S), Augmentation (A), Modification (M), and Redefinition (R).
The problem with many personalized learning tools is that they live mostly in realm of Substitution or Augmentation tasks.
It’s in moments like these that we see the SAMR model, while laying an excellent foundation, isn’t enough. When considering which technologies to incorporate into my teaching, I like to consider four key questions, each of which build upon strong foundation that SAMR provides.
1. Does the technology help to minimize complexity?
2. Does the technology help to maximize the individual power and potential of all learners in the room?
use Popplet and iCardSort regularly in my classroom—flexible tools that allow my students to demonstrate their thinking through concept mapping and sorting words and ideas.
3. Will the technology help us to do something previously unimaginable?
4. Will the technology preserve or enhance human connection in the classroom?
Social media is a modern-day breakthrough in human connection and communication. While there are clear consequences to social media culture, there are clear upsides as well. Seesaw, a platform for student-driven digital portfolios, is an excellent example of a tool that enhances human connection.

OneNote is the obvious choice for anyone who is using a Microsoft Surface or other Windows-based tablet. It is also available to use on iPads and on Android tablets. The option to have handwriting converted to text is an outstanding feature.
If you’re a G Suite for Education user, Google Keep. It doesn’t have the handwriting-to-text function that OneNote offers.
Zoho Notebook doesn’t have the name recognition of OneNote or Keep. Zoho Notebook has the most intuitive design or organization options of the three digital notebooks featured here.
The downside to Zoho Notebook is that the handwriting option only appears on the Android and iOS platforms. If the handwriting option worked in the Chrome or Edge web browsers,

Major trends in NLP: a review of 20 years of ACL research

Data: working around the bottlenecks
large data is inherently noisy. \In general, the more “democratic” the production channel, the dirtier the data – which means that more effort has to be spent on its cleaning. For example, data from social media will require a longer cleaning pipeline. Among others, you will need to deal with extravagancies of self-expression like smileys and irregular punctuation, which are normally absent in more formal settings such as scientific papers or legal contracts.
The other major challenge is the labeled data bottleneck
crowd-sourcing and Training Data as a Service (TDaaS). On the other hand, a range of automatic workarounds for the creation of annotated datasets have also been suggested in the machine learning community.
Algorithms: a chain of disruptions in Deep Learning
Neural Networks are the workhorse of Deep Learning (cf. Goldberg and Hirst (2017) for an introduction of the basic architectures in the NLP context). Convolutional Neural Networks have seen an increase in the past years, whereas the popularity of the traditional Recurrent Neural Network (RNN) is dropping. This is due, on the one hand, to the availability of more efficient RNN-based architectures such as LSTM and GRU. On the other hand, a new and pretty disruptive mechanism for sequential processing – attention – has been introduced in the sequence-to-sequence (seq2seq) model by Sutskever et al. (2014).
Consolidating various NLP tasks
the three “global” NLP development curves – syntax, semantics and context awareness
the third curve – the awareness of a larger context – has already become one of the main drivers behind new Deep Learning algorithms.
A note on multilingual research
Think of different languages as different lenses through which we view the same world – they share many properties, a fact that is fully accommodated by modern learning algorithms with their increasing power for abstraction and generalization.
Spurred by the global AI hype, the NLP field is exploding with new approaches and disruptive improvements. There is a shift towards modeling meaning and context dependence, probably the most universal and challenging fact of human language. The generalisation power of modern algorithms allows for efficient scaling across different tasks, languages and datasets, thus significantly speeding up the ROI cycle of NLP developments and allowing for a flexible and efficient integration of NLP into individual business scenarios.
