Beyond the Horizon Webinar on Student Data

March 29, 2017 @ 12-1pm US Central Time

NMC Beyond the Horizon > Integrating Student Data Across Platforms

The growing use of data mining software in online education has great potential to support student success by identifying and reaching out to struggling students and streamlining the path to graduation. This can be a challenge for institutions that are using a variety of technology systems that are not integrated with each other. As institutions implement learning management systems, degree planning technologies, early alert systems, and tutor scheduling that promote increased interactions among various stakeholders, there is a need for centralized aggregation of these data to provide students with holistic support that improves learning outcomes. Join us to hear from an institutional exemplar who is building solutions that integrate student data across platforms. Then work with peers to address challenges and develop solutions of your own.

CIA hacks

WikiLeaks: Here’s how the CIA hacks your phones, TVs and PCs

The organization released thousands of documents it claims show how the US spy agency can crack open devices from Apple, Samsung, Google and Microsoft.

This debate took off when the US Department of Justice sought to require Apple to help it open an encrypted iPhone belonging to one of the San Bernardino shooters. After Apple fought back in court, the FBI said it had obtained another way to access the phone.

Apple, Google and Motorola declined to comment on WikiLeaks’ claims. Samsung didn’t respond to a request for comment.

“The CIA/Wikileaks story today is about getting malware onto phones, none of the exploits are in Signal or break Signal Protocol encryption,” said Moxie Marlinspike, the founder of Signal. “This story isn’t about Signal or WhatsApp, but to the extent that it is, we see it as confirmation that what we’re doing is working.”

Telegram said on its website that the problem lies with operating systems and not encrypted messaging apps and that naming specific encrypted services is “misleading.” WhatsApp declined to comment.

avoid power point

Universities should ban PowerPoint — It makes students stupid and professors boring

http://www.businessinsider.com/universities-should-ban-powerpoint-it-makes-students-stupid-and-professors-boring-2015-6

An article in The Conversation recently argued universities should ban PowerPoint because it makes students stupid and professors boring.

Originally for Macintosh, the company that designed it was bought by Microsoft. After its launch the software was increasingly targeted at business professionals, especially consultants and busy salespeople.

As it turns out, PowerPoint has not empowered academia. The basic problem is that a lecturer isn’t intended to be selling bullet point knowledge to students, rather they should be making the students encounter problems. Such a learning process is slow and arduous, and cannot be summed up neatly. PowerPoint produces stupidity, which is why some, such as American statistician Edward Tufte have said it is “evil”.

Of course, new presentation technologies like Prezi, SlideRocket or Impress add a lot of new features and 3D animation, yet I’d argue they only make things worse. A moot point doesn’t become relevant by moving in mysterious ways. The truth is that PowerPoints actually are hard to follow and if you miss one point you are often lost.

While successfully banning Facebook and other use of social media in our masters programme in philosophy and business at Copenhagen Business School, we have also recently banned teachers using PowerPoint. Here we are in sync with the US armed forces, where Brigadier-General Herbert McMaster banned it because it was regarded as a poor tool for decision-making.

Courses designed around slides therefore propagate the myth that students can become skilled and knowledgeable without working through dozens of books, hundreds of articles and thousands of problems.

review  of research on PowerPoint found that while students liked PowerPoint better than overhead transparencies, PowerPoint did not increase learning or grades

Research comparing teaching based on slides against other methods such as problem-based learning – where students develop knowledge and skills by confronting realistic, challenging problems – predominantly supports alternative methods.

PowerPoint slides are toxic to education for three main reasons:

  1. Slides discourage complex thinking.
  2. students come to think of a course as a set of slides. Good teachers who present realistic complexity and ambiguity are criticised for being unclear. Teachers who eschew bullet points for graphical slides are criticised for not providing proper notes.
  3. Slides discourage reasonable expectations

Measuring the wrong things

If slide shows are so bad, why are they so popular?

Exams, term papers and group projects ostensibly measure knowledge or ability. Learning is the change in knowledge and skills and therefore must be measured over time.

When we do attempt to measure learning, the results are not pretty. US researchers found that a third of American undergraduates demonstrated no significant improvement in learning over their four-year degree programs.

They tested students in the beginning, middle and end of their degrees using the Collegiate Learning Assessment, an instrument that tests skills any degree should improve –  analytic reasoning, critical thinking, problem solving and writing.

Lenovo VR headset

Lenovo Showcases Affordable VR Headset at CES 2017

By Sri Ravipati 01/05/17

https://thejournal.com/articles/2017/01/05/lenovo-showcases-affordable-vr-headset-at-ces-2017.aspx

Last year at the Windows 10 event, Microsoft announced a slate of upcoming Windows-compatible virtual reality (VR) headsets from Acer, ASUS, Dell, HP and other PC manufacturers that would work without desk- or wall-mounted sensors (similar to its HoloLens device). Lenovo is the first to showcase the prototype for its own self-contained VR headset, which is making its debut this week at the annual International Consumer Electronics Show (CES) in Las Vegas.

Lenovo’s prototype headset is compatible with Microsoft’s Windows Holographic platform. Like the HoloLens, its design features depth-sending cameras located on the front of the device, allowing full-room movement tracking.
