Planning for AppleTV in the Lab

Ever since I heard that the next version of the Mac OS will feature support for AirPlay, I’ve been working on plans to use it in my teaching lab. Here’s what I have in process in terms of nuts and bolts:

  • a large flat panel monitor mounted in the front corner of the lab
  • an AppleTV connected to the monitor via HDMI cable
  • several Macs and iPads to serve as interfaces to drive the monitor

As of today I’m just waiting on our building support staff to mount the monitor and I’ll be off and experimenting. With four students in the lab for the summer, I’m sure it will get a proper break-in. I hope to convince them to try using it for research and not just streaming shows on Netflix, but we’ll see how that goes.

My plans for it include shooting and editing several short videos on common techniques we use in my lab. I could have these available for streaming on the monitor at the drop of a hat, so if a student asks how to make media or sterilize seeds or run a gel, they can refer to a video clip to refresh their memory. I also plan to have a collection of graphics that I can use for reference during pre-lab discussions. I expect to experiment with how best to store, organize, and stream these reference materials, as I’m not sure yet what will be easiest to use in the moment as well as for students to use on their own. I’m also eager to experiment with using apps live and projected on the big screen, but I’ll wait to discuss those until I’ve had a chance to play with my setup.

Canvas is a Delightful Departure

As I’ve shared previously, I’m restless with the technology I use for teaching, especially the LMS. Rather than only complain about it, I choose to experiment with other tools in the hope that I’ll find a better fit for my style. This term I’m experimenting with Canvas, the latest darling of the educational tech scene, and I’ve found its excellent reputation to be mostly well-deserved.

For starters, the fact that I can use it to host an actual class is the result of the fact that Canvas is a cloud-based LMS that is free for individual faculty members. The only practical limitations that I’ve found include a cap on the storage space per class and the need to upload my own roster and ask students to create accounts. Neither of these have been big points of pain for me, but if you need to host many large presentation files you may run out of storage space or have to rotate files off throughout the semester.

In the big picture, these are low costs to pay for the chance to use an LMS with an elegant user interface and straightforward usability features. If you are of the opinion that “design” is just how something looks, I challenge you to compare Canvas to the other big LMS out there. You will conclude that design is how something works, it’s made that well.

That said, there are still unintuitive aspects to its design. For example, my class just completed peer reviews of a writing assignment. These reviews were a cinch to assign, and I assumed the students would see their assignment in their ‘Recent Activity’ stream. But to get their assignment, they had to go to the assignment page and look for it, something that never occurred to any of them. Thirteen email replies later and lots of links to the help section, the problem was solved, but still, it might be nice if they could add this to the activity stream.

I still don’t want to rely on an LMS completely, at least in part for philosophical reasons, I’ll admit. But Canvas has been great for what I’ve used it to do, and it’s made it dead simple to do paperless grading (their Speedgrader iPad app is excellent). I don’t feel like I have to feed it my whole course, to fill in all the spaces with content. It works for what I want it to do, and stays out of my face for the rest. That’s pretty good, I’d say.

iA Writer Feels Like the Future

I tweeted earlier today that I was smitten with a new pair of apps, both called iA Writer. One is for the Mac and the other for iOS, and both are awesome on their own merits. They really shine, though, when used in parallel with iCloud.

special keyboard in iA WriterI’ve been doing significant writing on my iPad for the better part of a year and a half, and I’ve used a number of apps to do it. The first thing I noticed with the iOS version of Writer is the souped-up keyboard, which adds a single strip of keys and navigation buttons that makes writing and editing easier. The navigation keys include left and right arrows to move the cursor precisely and, on the iPad, keys that move the cursor one word at a time through your text. Both of these are huge time savers over the cursor placement loop. The other additional keys are for inserting commonly used punctuation, and having these on the primary keyboard is also a nice convenience.

The second feature that struck me is how seamless it is to work on a document across devices. To put it simply, you don’t have to understand or even think about file management, it just works. I can start writing something on the iPad and it’s just there on the Mac, where I can edit or add to it, and when I open it again on the iPad it’s all just there. Seamless. Behind the scenes the apps are both using my iCloud account to store the “master copy” of the file – what Steve Jobs meant when he said, “the truth is in the cloud.” There is no dragging the file in from the desktop, no pushing it out from the iOS app, it’s just there on both. This is awesome, and it demonstrates a different way to use “the cloud” from an approach like Google’s, where your documents are in the cloud and that’s where you interact with them. In the Apple cloud approach, I get to use a refined, custom, specific app to interact with my document, an app that is purpose-built for writing.

That brings me to my last observation, one that many others have commented on, which is the austerity of the editing experience in iA Writer. A lot of people wrote about the “focus mode” gimmick when these first shipped, but that’s not even the boldest design feature to my mind. These apps get out of my way and let me focus on writing like no others I have tried. I can’t tweak the fonts, the page size, the colors, anything. That’s a good thing – it is what it is, take it or leave it. Speaking of writing, it’s time I got back to work, but I just wanted to pass along how nice this pair of apps works together – feels like the future.

DRM on e-books should go

This is seeming more and more like the only reasonable next move for publishers:

By foolishly insisting on DRM, and then selling to Amazon on a wholesale basis, the publishers handed Amazon a monopoly on their customers—and thereby empowered a predatory monopsony. […] If the major publishers switch to selling ebooks without DRM, then they can enable customers to buy books from a variety of outlets and move away from the walled garden of the Kindle store.

Unfortunately, it will probably take a good five years for them to realize that the basis of power for Amazon is the closed format insisted upon by the publishers themselves. The other wonderful byproduct of eliminating DRM would be the ability to share an e-book with a friend, something that is not possible now.

Facebook’s targeting machine

If you, like me, have doubted whether Facebook could live up to its valuation, you should read this:

So if you want to reach the 100 people on Facebook who live in California, are between 18 and 36 years old, like “space” and work at Apple or Google, you can. Amazing.

The specificity of targeting ads to users based on their self-revealed interests is staggering. When I read the example in the linked article, all the pieces fit together for me, and I agree with the article — Google should be worried.

No Such Thing as Natural Foods

I mentioned previously how much I was looking forward to the series of food posts on a Smithsonian blog called Design Decoded, and it did not disappoint. From the last post of the series:

While mandarins are natural, in the sense that they grow on trees planted in soil, the popular varieties sold in the supermarket are the product of decades of human intervention. In other words: they are heavily designed.

There is, I think, a fascinating tension in our understanding of food, and this quote gets at the heart of it. In part, it has to do with our use of the term ‘natural’ as an approximation for a whole bunch of intentions. When we call a food natural we probably also mean healthful and wholesome and pure, and on some level believe it could not hurt us. But almost nothing we eat is actually natural, in the sense that it exists in the same form in nature. All food, almost by definition, has co-evolved with humans for thousands of years, being chosen out of a wild population for some favored quality and selectively propagated through the generations. What the series of posts at Design Decoded points out is that now we have added marketability to the list of qualities under selection for a growing number of produce items, which is, I guess, the natural progression of things.

Publicly Owned Internet Service

The Case for Publicly Owned Internet Service:

Right now, state legislatures – where the incumbents wield great power – are keeping towns and cities in the U.S. from making their own choices about their communications networks. Meanwhile, municipalities, cooperatives and small independent companies are practically the only entities building globally competitive networks these days. Both AT&T and Verizon have ceased the expansion of next-generation fiber installations across the U.S., and the cable companies’ services greatly favor downloads over uploads.

Such a shame there is almost no real competition in broadband service. I’ve often wondered if one solution to the lack of investment by the big players would be for communities to own their own networks. This column paints an ugly picture of the efforts these players will go to to keep that from happening.

The power of Keynote

A leading design firm uses Apple’s Keynote application for a lot of design work:

One of the most powerful features of Keynote is that is will take virtually any file that you throw at it. Images, vectors, video, audio, etc. can all be simply be dragged or pasted into your work area. Once in the work area, they can be resized nondestructively.

They use it in the idea-creation and mock-up stage of design, and they find it to be a nearly perfect tool for that purpose. My students and I have been using it to lay out large format scientific posters for years, and they find it much easier and more powerful than PowerPoint. The alignment guides that pop up and prompt you make a huge difference.

Lectures, Credentials, and the Disruption of College

There has been so much written lately about the imminent “disruption” of higher education as we know it. By disruption, pundits seem to mean something akin to the disruption experienced by most media companies over the past 5 years. Technology is the supposed driving force for the inevitable disruption, just as it was in the case of media publishers. As evidence for the disruption, thinkers point to the advent of online resources like Khan Academy, TED-Ed, the YouTube EDU portal, and several recent online courses offered by elite universities. For example, a recent article in Wired put it this way:

Fifty years from now, according to Thrun, there will be only 10 institutions in the whole world that deliver higher education.

As far as I can see, the disruption argument rests on the availability of two new(ish) resources. The first is a readily available source for high quality lecture materials. Many universities have been capturing lecture audio and video and posting them online as podcasts for years. The OpenCourseWare movement has also been working toward this objective for years. We’re now at a point where nearly every core subject has outstanding lecture materials available online for free.

The second pillar of the disruption argument is that a new system of credentials is emerging that circumvents the “college degree” certification and all it signifies to a potential employer. Here is Kevin Carey writing in The New Republic (linked above):

[…] the single greatest asset held by traditional colleges and universities is their exclusive franchise for the production and sale of higher education credentials.

And again later in the same piece:

But just as people are ultimately interested in buying holes, not drills, higher education consumers aren’t buying courses or degree programs. They’re buying credentials.

The argument here (I think) is that independent students will earn certificates symbolizing their completion of a course through an independent educational entity. These credentials will eventually gain recognition by employers as bona fide indicators of that individual’s competency in a field of study and warrant their consideration for a particular job position. Please excuse my taking liberty with connecting the dots in this way, as I have never actually seen anybody else spell it out.

Is access to information the problem?

First let me state that I do think there is plenty of change coming to higher education, much of it as a consequence of technological disruption. For a variety of reasons, I think the changes will serve to enhance already-existing institutions and not hasten their demise. As for the first argument, free access to educational materials online, I think this is wonderful, but it mostly serves the existing institutional structure far better than it serves the independent learner. I don’t think there is anything magical that will happen with access to recorded lectures because I don’t think this is the limiting step in the educational process. Motivated people have had access to such information as long as we’ve had books and libraries. In my opinion, the limiting step in education is for the individual to know where to focus amidst a sea of information. In this sense, the more information becomes available online, the harder it becomes for the learner to make progress without personal input.

To illustrate this, think of the process of advancing through the current education system. As you progress through the various levels of schooling, you become a more and more self-directed learner. Eventually, if you stick with it long enough, you complete the ultimate in self-directed learning, the Ph.D. This degree does not signify a person’s intellectual capacity, rather it signifies a person’s having become a master over a body of knowledge, fully self-directing and capable of adding to and extending the limits of that knowledge.

As some see impending doom on the horizon for higher ed, the idea of the ‘flipped classroom’ has also received renewed attention. This teaching method eschews the use of class time for traditional lecture, opting instead to discuss and assimilate knowledge. It relies on students coming to class already familiar with the information, ready to think and engage their minds (and not act like a room full of court recorders). This is not a new idea and is based on many years of studies of learning outcomes that support a more active classroom environment. If this discursive, personal, interactive process (and not listening to lectures) is indeed the best way for students to learn, how exactly does the availability of online lectures disrupt existing “delivery methods” in higher education? I argue that such resources serve as a pool of excellent materials for helping students to become familiar with a topic, but their real learning and intellectual formation occurs when they come and interact around those ideas with their peers and an expert in the field (i.e. they come to class).

This is not to say that some small percentage of talented students couldn’t make progress toward competency on their own using only online lectures. But for the vast majority of students, becoming educated requires much more than being exposed to information, it requires struggle and community and questions and other things I’m not qualified to even identify. Maybe someday an online system will exist that allows for those kinds of things, but I’m nearly certain it doesn’t exist now. I also think that one of the main ingredients in effective education is other people. Call me old-fashioned, but when you think about your learning experiences, don’t most of them involve other people? Peers? A favorite teacher? Yeah, mine too.

Is an education all about credentialing?

As for the second argument, that the college diploma will be replaced with some collection of credentials, I think this misconstrues both the meaning and the purpose of education in general, and a college degree in particular. To think of the role of universities as dealing in the “production and sale of higher education credentials” (see quote above) is, in my opinion, a deeply cynical and flawed perspective along the lines of thinking of the role of a family vacation as producing a set of photographs. A credential is the formal recognition of a process of intellectual development and transformation. It is not, in and of itself, the point.

A deep problem with the talk about credentials, badges, and the rise of competency as a measure of qualification lies with the selection of courses: who chooses what to take? I would speculate that most students would choose only those courses they see as important. This is a terrible idea, because the student has no idea what they will need to know. As an academic advisor to mostly science students, I can reveal the stunning news that these students do not relish the opportunity to take courses in the humanities. I know, shocker, right? But they benefit in so many ways from doing so, it’s hard to overstate the importance of these courses in their academic development. They grow in broadened perspective, vocabulary, writing skill, logic, argument, rhetoric, friendship, tolerance, compassion. And once again, these are skills and virtues best acquired in a community.

The bottom line for me is that we’re in the midst of an explosion in the creation of information. The need for a broad education has never been greater. I think this increases the need for guidance, and I think the best guides are other people. I do believe our current colleges and universities need to change and adapt to incorporate new methods for educating people. And maybe we will see the rise of a new kind of educational enterprise that fills a need not met by a four-year college. I do think there are plenty of students enrolled in a four-year degree program with no business being there, but they have no other option. But I don’t think these new enterprises will replace our current colleges, not by a long shot.

Flowering out of sync

image of pear flowers
All dressed up, but nobody's coming over. This pear's pollinators are not showing up.
As you may have noticed if you live around here, spring came really early this year. In fact, winter barely came at all, so spring has kind of been brewing since late February. But temps were in the 80’s several days this week, so spring seemed to arrive for real this week. Our silver maple began flowering a couple weeks ago, and this week our two Cleveland Select pears burst into flower. As I was walking past/under the trees, holding my breath to avoid the rank odor they emit, I noticed something unexpected. Actually, what I noticed was nothing: there was not the usual cloud of tiny flying things around the flower clusters. I’ve now spent ten or so minutes each day over the last three days observing the flowers, and I’ve counted a grand total of 3 insects.

Let me acknowledge that I am not an expert in pollinator interactions, not by a long shot. [Note: for a real treat on these kinds of natural history and phenology topics, you should read Rebecca in the Woods.] It could well be that I’m just there watching at the wrong time of day, or mis-remembering past years’ pollinators, but I don’t think so. I think what I’m observing is a plant flowering far earlier than usual due to above-average temperatures. Meanwhile, its usual pollinators aren’t yet active. I think we can probably add this to the list of unexpected results of global climate change. In our case, I’m excited at the prospect of this tree not producing fruits — they’re messy and kind of a pain. But imagine if this were a fruit tree, or a whole orchard of fruit trees with no pollinators. Yikes.
