Polymaths Everywhere

“I had a terrible vision: I saw an encyclopedia walk up to a polymath and open him up.”

It seems like people have been talking about reforming college degrees “forever.” Obviously, this is not true, or maybe it is, academics are always trying to design something new. The redesigning of degree programs usually fall into one of two categories; time to degree, and employability after graduation. Concerns over cost is driving discussions about time to degree and employability. The argument is if it takes less time to earn a degree, it will cost less, therefore, make it more accessible and affordable. The case for employability is that degrees should focus on skills that employers want so that degrees are a better investment.

Just recently, I read about another degree idea, the polymath degree. Project polymath run by The Polymath Foundation offers such a degree. The idea behind the project is to create a school that trains polymaths, individuals that “think” like da Vinci. According to Merriam-Webster, a polymath is “a person of encyclopedic learning,” according to Wikipedia a polymath is “a person whose expertise spans a significant number of subject areas, known to draw on complex bodies of knowledge to solve specific problems.”

In the polymath project, projects are the center of the educational experience. It seems to me that a lot of these projects are focused on industry partners and creating startups; in fact, the school lists professional applications as the most critical metric in their educational system. The degree will be the standard four years in length but student, with the help of mentors, follow education units rather than courses.

In addition to Project Polymath, there is also the London Interdisciplinary School (LIS) which offers a similar program to Project Polymath. Both programs talk about needing a new approach to solve today’s complex problems. They argue that issues stretch across disciplinary boundaries, so education needs to as well. LIS describes their coursework as,

“We believe that real-world problems require an interdisciplinary approach. This is why we offer one course that cuts across disciplinary boundaries. Our course takes the most fundamental theories and knowledge areas from across the arts, sciences, and humanities and applies them to real-world problems.”

In addition to employability, polymath degrees are an obvious counter to the increasing number of specialized college degrees. I am a little concerned with over specialization. When I graduated with my BS in Biology in ’97, the only biology degree you could get at my school was Biology. In 2019 that same school offers five specialized, or as they call it areas of emphasis, Biology degrees.

However, the fact that I earned BS degrees in both Biology and Biochemistry also shows that I do have a strong belief in cross-disciplinary training. However, unlike these polymath programs, I graduated with the additional credits for the two degrees 240 instead of 180. However, the real question is what is the balance needed between breadth and depth in a Bachelors degree.

The question of depth versus breadth is not a simple one. In addition to what you need for a successful degree, there is the fact that information is continually growing. Buckminster Fuller proposed the knowledge doubling curve in his book Critical Path. The knowledge doubling corve shows the rate at which knowledge doubles from year 1 to about 1945. If we took all the information created by the human race until year one as one unit it took till the year 1500 to double it, the next doubling occurred in 1750. By the end of World War II knowledge was doubling every 25 years. According to IBM’s Toxic Terabyte by the mid-2010s knowledge doubling time will decrease to hours.

The increasing amount of knowledge is one of the driving reasons for the growing number of specialized degrees. As the amount of knowledge increases the information an individual has to learn in their “field” increases. Eventually, it starts getting difficult to fit everything into four years. When this point is reached rather than change the structure of the degree like adding a year (after all life expectancy increased by 34 years from 1900-2000) schools created degrees with a narrower focus. It is indeed legitimate to ask; when do degrees get to narrow to be useful?

One of the counters to specialized degrees is a Polymath Degree. However, do polymath degrees even work from an educational point? Only time and hopefully, research will tell. Additionally, even if a Polymath degree works are they the correct solution to specialized degrees? A Polymath degree covers the fundamental theories and analytical methods across multiple disciplines. However, can students learn the information Polymath programs teach without learning the foundational information?

Alternatively, can you learn to properly use higher order thinking skills without first learning the lower order thinking skills? I don’t think so. We often forget a large part of first and second-year courses is learning the language of the field. As I have written about previously (The Language of the Field), the same words have a different meaning in different fields. If students don’t understand the meaning of the words, they can’t understand the nuances of theories and methodologies in a field.

The Polymath degree is designed to deal with what some see as problems in higher education. While I think the growth of highly specialized degrees, especially at the undergraduate level, are concerning I don’t think the solution is to create degrees without depth. I would like to see time added to undergraduate degrees to take into account the growth in knowledge. However, until we get a grip on the rising cost of education, lengthening the time of a bachelors degree will not happen.

Polymath degrees are an idea to reform higher education. One way or another, I look forward to seeing real research about student learning in these polymath programs. Maybe I will be wrong, and Polymath degrees will work, I’m not holding my breath. Even if polymath degrees work, there will still be a need for degrees with greater depth, traditional Bachelors degrees.

To Be Digital or Not to Be Digital

“Real knowledge is to know the extent of one’s ignorance.”
Confucius

The debate about textbooks and the cost of textbooks has become so large that governments are getting involved. In 2009 California passed SB 48 An act to add Section 66410 to the Education Code, relating to college textbooks. This bill requires publishers of College textbooks to make the books sold to the State schools (Diversities of California, the California State universities, and the California Community College system) available in digital format by 2020.

In 2011 Florida passed SB 2120 which added similar legislation for Florida schools. Several other states have passed bills relaxing regulations on the money assigned to textbooks to allow digital content to be purchased instead of traditional printed material.

Of course, even with these rules, there are still questions concerning digital books. One question is what do the students think about Digital textbooks? Several surveys have shown that e-textbooks (e-texts) have had slow sales, in 2010 e-texts accounted for only 2-3% of textbook sales, in 2012 e-text sales had grown to only 11%. The slow growth in e-texts sales is different than other types of e-books, as Amazon announced in 2010 that it was selling more digital than print books.

With the growth in sales of fiction and nonfiction e-books coupled with advantages like lower cost, more comfortable transport (weight), and the addition of multimedia and connected content it seems like e-texts should be growing exponentially. So why aren’t they? One reason might be the availability of the reader. While I read all my entertainment books in a digital format, I rarely read them on my laptop or desktop computer. I read them on my tablet or dedicated e-ink reader. According to the 2017 Educause study ECAR Study of Undergraduate Students and Information Technology, 2017 While smartphones have reached near-saturation only about 50% of the students surveyed own a tablet. The presence of pictures, multimedia and formatting make e-texts challenging to use on smartphones; therefore another reading device is needed which 50% of the students don’t have.

If the availability of “reading” devices is the primary reason for the slow adoption of e-texts by students, there is an easy solution for governments and schools wishing to encourage the transition. The schools need to provide “readers” like they provide other educational tools. However, before we run out and change regulations we should ask is the lack of “readers” is the primary reason students are not adopting e-texts?

There is plenty of evidence that suggests there are other reasons students are not adopting e-texts. The current generation of undergraduate students is digital natives. Which means they are familiar and comfortable around technology. We might expect them to flock to e-texts. However, we need to remember that schools are historically slow to change how they do things in the classroom, even if they have the money to make changes. Authors Win Shih and Martha Allen in their article Working with Generation‐D: adopting and adapting to cultural learning and change point out that while the current students are digital natives. The students have not grown up with digital technology in their educational environment. Therefore the slow adoption of e-texts could be the students wish to stick with what they know.

Another interesting thing is that students confidence in their ability to use e-texts effectively has decreased over time. In 2012 60% of surveyed students felt they could effectively use e-texts while in 2016 only 44% said they could effectively use e-texts. (deNoyelles, A. and Raible, J. Exploring the Use of E-Textbooks in Higher Education: A Multiyear Study, EDUCAUSE Review, Monday, October 9, 2017) This decrease in comfort is unusual since students comfort with technology should be increasing as students grow up surrounded by more and more technology.

Where this decrease in comfort is coming from is an interesting question. A possible explanation could be the increased interactive and multimedia content in e-texts. In addition to searching, highlighting, and bookmarking features, e-texts have started to include features to ask questions, annotations, and chat with fellow students and faculty. All of these connected functions are in addition to the multimedia and linked content.

As I have written about previously (Shh I’m hunting (for) Digital Natives) Digital Natives while comfortable with technology do not have a deep understanding of how it works. Many faculty don’t understand this and fearful of looking foolish in front of their students don’t use, demonstrate, and model the educational technology used in their class. Because of this lack of training student might feel like they don’t understand how they should be using the e-texts.

Alternatively, since the use of e-texts has increased 24% over the same period as the students’ comfort has decreased
(deNoyelles, A. and Raible, J.Exploring the Use of E-Textbooks in Higher Education: A Multiyear Study, EDUCAUSE Review, Monday, October 9, 2017) , we might be seeing the Dunning-Kruger Effect . Early on in the adoption of e-texts, the students had so little self-knowledge about the use of e-texts they had no ability to judge their lack of skill and knowledge accurately. As time passed and the students gained experience with the e-texts they began to understand how much they didn’t know about the use of the e-text. More research is needed here.

While schools and governments have been quick to support e-texts for all there advantages, lowers cost, ease of portability, interactive and multimedia tools, and several (often incompletely implemented) accessibility features. Most of these groups have failed to look at the user population, the students. Recent studies from groups like Educause has shown that the ownership of dedicated reader devices like tablets has plateaued and may even be decreasing among college students. Additionally, while students are comfortable with technology the limited use of e-texts in K-12 means that students are more comfortable with regular print texts.

If we wish to continue with the increased adoption of e-texts we need to focus on working collaboratively across the whole of K-16. Students need to be comfortable and familiar with e-texts before they start college if we want e-texts to be used generally throughout college. To increase the successes of e-texts in education faculty also need to use and model e-texts in their classrooms so that students understand how to use them. Lastly, schools need to develop strategies to help students select and acquirer devices that will let the students get the most out of the e-text. Most importantly we need to remember e-texts will only work if the end user, the student, finds them helpful, compelling, and affordable.

Why Do You Teach?

“I never teach my pupils, I only attempt to provide the conditions in which they can learn.”
Albert Einstein

I have been interested in the improvement of education throughout my life. During my late Graduate student and early professional years, I attended many workshops on Discipline-Based Educational Research (DBER). In these early days, the workshops and associated discussions were not well organized and would often range far and wide. The birth of organizations like the Khan Academy, Massive Open Online Courses (MOOCs), and other internet-based educational tools around the same time lead to a plethora of articles announcing that the Face-to-Face university was on its last leg and would soon die.

One of our discussions revolved around why the loss of face-to-face classes would be a tragedy. All the professors started by saying face-to-face classes were always superior to online (something I am not sure I agree with, but that is a different discussion) because of all the advantages the students got. Then for the next hour, the faculty discussed how they always get great ideas from their students, how the students think of things the professors did not, and how they taught so much better when interacting with the students. I remember asking “everything you just talked about are benefits to you what about the students? Shouldn’t we be talking about what they get?” I never got an answer.

Just recently I read an article The Subtle Erosion of Academic Freedom from Inside Higher Ed. The paper starts by saying that President Trump’s executive order about free speech while problematic is also distracting from the real loss of academic freedom. The author Professor Johann N. Neem argues that three things are undermining academic freedom. The first is the decline of tenure and shared governance; the next two surprised me. The second point undermining academic freedom is schools that offer degrees but don’t require “professors” to teach the courses specifically schools like Western Governors University or Southern New Hampshire University’s College for America. The third issue undermining academic freedom is the growing number of students that earn college credit through things like Advanced Placement.

Why does Professor Neem feel AP credit is undermining Academic freedom? Neem states “Yet a moment’s thought makes it clear that AP courses are nothing like college classes. They may be rigorous, but that does not make a course worthy of college credit. A college course is defined by the presence of a professor who is an expert in their subject and the freedom of that professor to pursue truth in the classroom and scholarship. … however, what defines a college course is freedom to seek truth far more than how hard a class is”

This argument that the essential thing in a college course is that the Professors can seek the “truth” drives the remainder of the paper. According to Webster’s dictionary, Truth means


  1. (a)
      i. : the body of real things, events, and facts: ACTUALITY
      ii. : the state of being the case: FACT
      iii. : often capitalized: a transcendent fundamental or spiritual reality

    (b): a judgment, proposition, or idea that is true or accepted as true
    (c): the body of true statements and propositions

So how does truth affect AP courses “ … AP courses, even if more rigorous, are less like college courses than even traditional high school courses because AP teachers must teach to a predesigned test …” lets think about this idea a little if a course can’t be “college worthy” because the teachers don’t have the ability to seek real things, events, and facts what about American Chemical Society (ACS) certified programs. Since ACS certified programs have curricular requirements, does that mean an ACS certified Bachelors degree is not a college education?

One of the arguments as to why schools like Western Governors is not worth a “college” degree as Neem states is “Students themselves do not interact directly with professors but with standardized online modules and learning “coaches” and “mentors” hired to implement a pre-existing curriculum.” While I do not personally know every coach and mentor at Western Governors University the ones, I do know care a lot about education. Many “professors” don’t really care about education. I have lost count of the number of professors at high-end universities that have told me “I do as little teaching as possible,” “teaching is the lest import thing I do,” and “I put as little effort into teaching as I can.” Additionally, graduate students taught 25% -33% of my classes which is not uncommon.

So if High School teachers teaching AP classes are not worthy of college credit because as Professor Neem said “ … high school teachers, who lack the expertise and autonomy to offer college-level instruction, teach such courses.” Then do we need to invalidate all the bachelor’s degrees where graduate students have taught courses?

Just like the discussion I had years ago everything in Professor Neem’s article is about what the professors get not what the students get. Everything presented is opinion with little or no fact backing it up. Where is the evidence that shows students that graduate from schools like Western Governors or students that have AP credit do not do as well or have a “weaker” education than other students? I suspect there is no evidence presented because there is none. After all, when it comes to online education it has already been shown there is No Significant Difference.

If you want to argue that Universities and academic freedom are central to the quality of a students education, explain why with examples and evidence. After all, everything changes over time, just because something is new does not mean its wrong. If seeking the truth is the most important thing in education then instead of just complaining about differences put some real thought into the issue and conduct research to prove it (if you can).

Should You be Replaced By A Computer?

“Any teacher that can be replaced by a computer, deserves to be.”
David Thornburg

Whether as part of a talk, training session, or some other event everyone that has worked in educational technology has probably been asked the question “Are you trying to replace teachers with a computer?” Or heard the statement “You are trying to replace teachers with computers!”

Educational technologists are not trying to replace teachers. Educational technology is meant to enhance the teaching and learning experience. The goal of ed tech is to help the teacher and student so they can focus on learning efficiently. Ed tech is meant to solve problems in the learning environment so that teachers can get back to the job of guiding and interacting with the student. One of the uses of educational technology is to help with basic tasks so the teacher can focus on the things only they can do.

The core idea behind David Thornburg statement “Any teacher that can be replaced by a computer, deserves to be.” Is there are things that only a live teacher can do. Therefore, if a computer can do the things a teacher is doing, there is no point in having the teacher. Teachers should focus on the tasks that only they can do. However, like all types of technology in the classroom, we should discuss the idea of computer run education before it happens.

As a starting point for a discussion of computer run education, we should start with the questions; “what can technology do right now?” The reason for this discussion is that at some point technology is going to reach a point that from at least a financial standpoint people will consider replacing teachers with computers.

There are two places where computers can replace teachers in the face-to-face classroom and the online classroom. Let’s start with the online class. Most online classrooms are asynchronous. That means the students do not have a lot of real-time interactions with their teachers. Most of the communication is through email, text messages, and hopefully phone calls or audio conferences. While it is possible it is difficult to make connections and have real personal interactions with students in this environment.

Starting with communication can computers answer email, text, and voice chats/calls? Historically, automated computer response systems suffer from the inability to understand common spoken or written language what is called natural language. However, in 2011 IBM’s unveiled an Artificial Intelligence (AI) questions answering system (Q&A) named Watson. The systems competed on the game show Jeopardy and won, you can read about it here. Watson showed that natural language understanding in a computer had arrived. Since then Watson has only improved and is now used in many industries including finance, healthcare, and education.

Two of Watson’s tools are especially useful to education. A one-to-one tutoring tool that gives real-time tutoring to students when its covenant for them. The other is a natural language chatbot. These AI tools allows the students to ask questions and get feedback in real-time. Additionally, both tools can respond to typed and spoken language.

So a natural language Q&A system like Watson can cover the basic communication needs, usually done through email, text messaging, and voice. What about assignments and tests? All current generation learning management systems can already handle multiple choice, true/false, matching, and single word answer questions.

That leaves the short answer, discussion boards, essays, and reports. There is a software tool called General Architecture for Text Engineering (GATE) a natural language text analysis tool that uses both rule-based analysis and neural net learning. Using this tool students would be able to get feedback on written assignments as well as automated grading on final drafts.

The tools discussed here are only some of the options developed in the last 10 to 15 years. However, looking at just the tools discussed in this blog and based on the modern structure of most online classes we already have the means to replace teachers. Again our research and discussions are lagging what we can do.

Concerning face-to-face classes, the national language AI’s are not quite at the point where they can run multiple participant discussions and give lectures — assuming we except lectures out of thin air. However, natural language AI systems will probably have the ability to run multi-person discussions or give lectures within the next 5-10 years. Augmented reality, virtual reality, and projection systems will also provide natural language AI systems the ability to have a physical presence in the next 10 to 20 years.

Contrary to previous times AI systems with natural language understanding are reaching a point where at least in theory they could replace teachers. We are desperately in need of research that shows what impact AI “teachers” have on learning and the classroom. Additionally, now is the time to have real thoughtful discussions about AI tools in education not in a couple of years when government/administration starts adding them to classrooms. We need to decide not merely what we are willing to let the AI system do in education but why we are making these decisions.

We Can Rebuild It, Better, Stronger: The Augmented Textbook

“VR and AR will eventually converge, and smart glasses will take over our digital interactions.”
Carlos López (Founder @ Oarsis)

Augmented Reality (AR) is a process that uses technology to overlay digital content on real-world objects.  The digital content can be provided by, smartphones, glasses, and screens.  While AR is still an emerging technology, the buy-in from major companies like Microsoft with the HoloLens, WebAR support in Google Chrome using ARCore, and Apple’s augmented reality development kit ARKit, likely mean this technology is here to stay.

While the form factor used in AR will undoubtedly go through multiple iterations the primary function overlying digital content will remain constant.  AR is a great place for higher education to embrace technology and stay current rather than playing catch-up.  While wearable AR tech is not yet coming place, we can use the near ubiquitous smartphone with augmented reality.

There are already educational AR tools developed both inside and outside of education.  The Dinosaur 4D+ flash cards by octagon studio bring Dinosaurs to life.  Using an app installed on an Android or Apple device the flash cards allow you to explore and interact with the cards, as you can see here.

The International Society for Technology in Education (ISTE) has a blog post by Larysa Nadolny Worksheets for the digital age: AR interactive print.  The author gives a brief overview of the creation of these AR worksheets using existing technology.  Case Western Reserve is using AR to help teach anatomy, using the Microsoft HoloLens.  Students can see the anatomical process in active 3D.

Publishing companies are also starting to use AR in their books.  Carlton Books has two categories of AR books an educational category including titles like Explore 360: The Tomb of Tutankhamun and iExplore – Bugs that use AR apps to bring the content to life and let the readers interact with it.  They also have a new category of fiction novels they are working on; the first is The Ghostkeeper’s Journal and Field Guide a book that uses AR to enhance the story and engage the reader.

Many companies are producing AR books. Currently, the publishers are mostly focusing on the children and youth market.  These books have evolved from some simple animations like moving gears and simple 3D animals to full multimedia that include animations, sound, and interactivity.  Some of these books like the previously mentioned The Ghostkeeper’s Journal and Field Guide were written to include the book and its AR content as part of the story.

I have previously discussed how storytelling is a powerful educational tool (you can read about it here), I wish it was used more in textbooks.  If AR can enhance storytelling like these publishers are suggesting it should also enhance learning. While some people think the AR in books is gimmicky, I think anything that increases engagement with books is good.  Also, with regards to AR being gimmicky while Arthur C Clark said: “any sufficiently advanced technology is indistinguishable from magic” technology doesn’t have to be “magical” to be effective in learning.

This discussion of AR and books brings me back to the idea of textbooks.  The addition of augmented reality to textbooks can enhance education.  Let’s start by thinking about the basic content in a textbook.  We could add something simple like sound.  Imagine a music appreciation course; the textbook could describe techniques used in improvisational jazz.  Say for instance arpeggio, where the musician plays the notes of a chord one after the other instead of together.  Think how much easier this would be to understand if the textbook could play clips of music with and without arpeggio.

In biology, we often talk about how seasonal changes affect the local ecology and behaviors of organisms.  A great example of this is the Amazon Floodplain forests.  A large area of the Amazonian forest that is flooded every year in the rainy session when the Amazon river is overflowing its banks. Textbooks will often show flooded, and dry pictures to show the effects of the flooding.  With AR you could show a time-lapse video of the flooding and retreating water to get a better idea of how the water affects the landscape.

Something I remember from my days as an undergraduate in chemistry and biology is the difficulty students have learning to translate a 2D model into 3D.  Molecules are 3D objects when writing about them; we need to represent them on paper.  A simple model would be the wedge and dash model used for methane below.

Structure of Methane By NEUROtiker Downloaded from Wikimedia Commons.
Structure of Methane By NEUROtiker Downloaded from Wikimedia Commons.

In the diagram, the solid wedge means the atom is projecting out of the paper towards you while the dotted wedge means the atom is projecting away. I was one of the lucky students I have always been able to picture the 3D shape of from these drawings rather easily. However, I have known a lot of people that have real trouble seeing the 3D form.

Now imagine if the textbook had AR we could design interactions that not only projected the molecule in 3D but let the students manipulate, rotate, and zoom in and out to examine them.  AR projections would be especially useful when you get into more complex structural issues like stereochemistry, were molecules have the same formula but differ in their shape.

A textbook on public speaking could include actual audio and video clips of famous speeches.  A math book could include video clips were professors solve example problems with explanations.  We already know that publishers are taking advantage of AR especially in the case of books for young audiences.  However, AR textbooks are starting to appear, Introductions to Graphics Communication is a college-level textbook using Ricoh’s Clickable Paper.  Publishing companies in Japan have released textbooks with AR; you can read about them here.

Even with the availability of many AR platforms some of which are Augment, Blippar, HP Reveal, Daqri and Layar that offer educational pricing.  I have not seen any Open Educational Resource (OER) textbooks with AR content even the textbooks developed with large federal or privet grants.  In addition to whether governmental and privet organizations will be willing to pay to update these OER textbooks in a few years, are we also going to end up in a situation where we have different classes of textbooks? Is there going to a case where if you can afford it you get a different textbook?

Augmented Reality is a technology that higher education needs to embrace.  We need to develop not only resources using AR but the tools, preferably in a free and opensource platform, we can use to incorporate into any resource where it makes sense.  Textbooks are a resource where AR makes a lot of sense.  Like I have said before we are in the middle of a revolution regarding textbooks it is critical that we don’t focus on just one aspect of the textbook.  We need to think about what we want a textbook to be in total, and one of the things we should add is AR.
