The uberization of everything

Had a discussion at a C2 organized, Michelin sponsored conference on mobility named “Movin’on” (I can’t say I agree with the title choice, but whatever) during which the owner of a trucking company admitted that the coming change in his industry is the “uberization” of the work.

Uberization = the transition from a client-provider relationship to an open bidding process based on an individual request. Instead of hiring a sub-contractor to perform a block of work (say Amazon hires company X for the following block of 14000 loads of merchandise transport), you open a bidding process on a per service basis (Amazon advertises individual loads to move, as they are available with an advertised price they’re willing to pay).

This had me thinking that “uberization”, in a way, is coming to teaching and academia. Youtube didn’t exist when I was a student. Nowadays, students routinely come to class and challenge a given concept with a partial explanation from a youtube video or another website. I’m not using the word “challenge” in an adversarial sense here, but actually as part of the learning process. In other words, the goal of the student is to go from (A) not knowing a concept to (B) understanding and applying a concept. The standard process is usually thought to be

  1. Prof (P) exposes concept (C) to Student (S), (usually in a group).
  2. P completes example of C to S.
  3. S reviews (usually alone) C.
  4. S applies C to simple problem.
  5. S applies C to harder problem.
  6. P tests S on C during exam or project.

The real process is actually a back and forth between prof and student, depending on the level of understanding of the student. This process is what I experienced when I was a student.

  1. P exposes C to S.
  2. P completes example C as demonstration.
  3. S reviews C.
  4. S attempts problems involving C.
  5. S challenges P with partially completed/incorrectly completed problems involving C.
  6. P demonstrates the missing/faulty parts in reasoning.
  7. Go back to step 3 as needed.
  8. P tests S on C during exam or project.

More and more, though, I have students challenging me with outside knowledge. This process is new to me.

  1. P exposes C to S and completes example using C. (This part is often skipped by S.)
  2. S reviews C from P material and from outside material (youtube, Kahn academy, etc).
  3. S challenges P regarding C using material from a variety of sources.
  4. P demonstrates the missing/faulty parts in reasoning and in outside material.
  5. Go back to step 2 as needed.
  6. P tests S on C during exam or project.

The next logical step is that we do away with step 1 altogether and students “pull” information from professors as needed. There’s no class anymore, the student is learning on their own and challenges P (of their choosing) on C using their material. Sherbrooke university actually tried this approach starting some time in 1998-1999. They introduced a pure project based learning approach with no classes. The university eventually “dialed back” the project-based approach and re-introduced more formal classes for, at least, basic concepts. The problem with the pure “pull model” of learning is that

  • a novice does not have the knowledge to know what to look for nor how to look for it
  • without a constant interaction between students and professors, I have less opportunity to direct specific students to specific projects, specific professors, or specific concepts depending on their skill set, interests, etc. (I actually do this. I hire undergraduates to work on research. I have undergraduate students referred to me by other professors to work on projects, etc.)
  • a novice does not have the skills to evaluate whether a given material is indeed correct or incorrect. I routinely get students challenging me with material that is either wrong or that does not correspond exactly to the material covered in the class. Sometimes, nomenclature is murky and different people and sources will name subtly different concepts by the same name. The novice is still learning the skills to spot those differences.

Right now, I would contend that universities are completely unprepared and maybe even unaware of the coming possibility of the uberization of education. In engineering, the only last resort protection of our model is that we have a regulating body enforcing a certain course of studies for students to be able to practice as engineers (at least in Quebec and certain other jurisdictions).

The question is then: “How do we, as universities and academics, adapt our teaching methods to retain an effective learning path for students while conforming to students’ expectations so that they don’t drop out of our system?”

PSA: Cover Letters

I’m guilty of writing shitty cover letters (I’m amazed I ever got a job). NPR Ed has a great write-up about cover letters. While it’s in the context of internship seekers, it all rings true for a job seeker as well. It’s also true for students. My name’s only been on the university website as an assistant Professor for 6 months and I already get 2-10 emails a week that are variations on the theme:

Dear [ respected | beloved | professor Kiyanda |sir ] ,

I have applied to your department at [your university | Concordia University | McGill University ] in [your department | Mechanical Engineering | Aerospace Engineering ] .  I have completed a [undergraduate | master’s ] degree in your field of [mechanical engineering | heat transfer | fluid flow | thermodynamics ]. My file is now complete for the [master’s | phd ] degree and I am looking for a supervisor. I would be delighted to work on the numerous projects you have listed on your website.

Student Name

File ID number

I usually just file those away in a folder because I have no idea what to do with those. Rarely, I’ll get a transcript. Never have I gotten anyone with even a half-page description of a project they like. Or maybe attach three papers you found interesting and discuss how they relate to each other. Maybe I’m biased because I always had a clear view of why I wanted to do a PhD, so I was never in that situation where I ended up applying to a master’s or PhD degree as a life alternative. That was always the path. I’m not that excited about PhD cold calls for a supervisor in the first place, but if you’re going to do it, you have to show me that you’re minimally interested. Enough to do a google scholar search on my name and figure out that I’m quite involved in detonation research. (Hint: for a young professor within 10 years of graduating, you might want to check their PhD thesis. There’s a high chance they’re looking to capitalize on offshoots of that work.)

Philosophical questions about the current US situation

(cross-posted on Facebook as a public update)
It’s not every day that one gets to have basic philosophical interrogations about a concrete action in one’s everyday, professional life.
 
I have two conferences coming up in the US. There is a (still looking small) number of canadian academics boycotting conferences taking place in the US in response to the US government’s ban, preventing people from certain countries to enter the country. I’m not personally affected and I don’t have students who are affected, but I’m forced to think about this issue. My university’s professional and student body is very diverse with many people from countries affected by the US government’s action. I have several colleagues who have immigrated from Iran. I am an assistant professor, tenure-track, but very much not tenured, so taking certain actions may very well have implications on my future. (Full disclosure: my personal tin-foil hat wearing theory is that the 7 country exclusion is the map of the current US administration’s view of zones under at least some iranian influence and potential conflict zones. My conspiracy theory is that the US administration is drawing the map of engagement in a developing conflict with Iran.)
 
Now, I have to wonder… Are the current actions of the US government legitimate? The administration may have the legal (or even moral) right to refuse entry to nationals of certain countries, but canceling already emitted refugee visas is, at least in my book, immoral. Does the fact that the judicial branch put a stay pending litigation mean that I should limit the level of actions that I take? After all, I may disagree with the administration’s decisions, but there are 3 branches of government in the US. This ban may end up never being put in place.
 
If you’re under 20 and wondering why society is making you take philosophy classes, this is it. The extremes are easy to judge, but times like now are the interesting grey areas that require long and hard thinking.

New “maker space” at Concordia

Really not so much a “maker space” as a “discover space”. It’s basically a library version of a maker space. Find it here: https://library.concordia.ca/locations/technology-sandbox/. An interesting concept if you have no experience with arduino, 3D printing, VR gear and more. I’m told it opens February 22nd 2017. I might just have to go around and have a look then.

I’m now an engineering professor

Well an assistant one at least. I’m already writing grant proposals, so I guess that makes me a real prof nonetheless.

ICDERS 2015 poster

I had a poster at icders 2015 this year on a version 0 of an online database for experimental HE data. I did put the address of my personal webiste on that poster, so you might have ended up here from there.

 

I couldn’t attend, but my colleague was nice enough to put the poster up and probably discuss a bit with some people. The whole point of the poster was to present the first pass at a database that is meant to be, in time, explorative and participative. By that, I mean that the goal is for people to use the interface as an exploration tool and not merely to download data and for researchers to share, submit, download, use data in a (relatively) simple format that facilitates things. The tone of the poster ended up being a little light-hearted, but the content was very real. The main criticism I’ve heard of the participative approach is that some sort of central command is needed to ensure the quality of the available data. I disagree and I gave a few examples, one of which is probably not very well known, yet is very close to what this project aims to be, that is openstreetmap.

OpenStreetMap (OSM)  is a participative and collective database that aims at mapping everything that is permanent in the world. There is no enforced tagging scheme in the database, so you can end up with competing nomenclature in the database. Everything is community decided and nothing is actually technically enforcable. The file format is akin to xml and hence is completely open. Nonetheless, the project is, I would say, unquestionnably succesful. Large organizations use openstreetmap as the backbone of their mapping needs. Some examples of that:

These examples, I hope, will convince you that the participative model can and has lead to high quality, reliable products in the recent past. This database project’s aim is to use a similar model in our field. Hopefully, this will be the start of a fruitful discussion.

Again, ff you want to try the databse, go here.

NB: It’s been pointed out to me that there was an overlay mistake in the poster and some words were cut off slightly. Annoingly, everything was fine in the original PPT file and it seems powerpoint screwed something up when the file got converted to a tiff for printing. This is highly annoying as I would kind of expect (and indeed use to trust) powerpoint to get “overlay of objects on a page” right as that’s kind of a core function of the software. Another reason to move towards open source and open data: auditability. The original poster is available here (Icders 2015 poster on HE database) if you’d like to see it.

How surprising is it actually that nurses were infected with Ebola in Texas?

I’ve been using twitter more and more (mostly given that I’m involved in a local Montreal openstreetmap group and I’m one of the two curating that twitter account) and recently got involved in a back and forth with @2closetocall about his following tweet:

@2closetocall: Ebola, this disease that is supposedly so hard to transmit… And yet we now have two nurses infected by one patient. Are the proba. right?

The exchange then went:

@cbkiyanda: @2closetocall yes, probs are right. The 3 Dallas cases are people who handled/medically cared for infected. Not random people on the street.

@2closetocall: @cbkiyanda but ehy also (at leats in theory) took way more protections than a random person

@cbkiyanda: @2closetocall which is why science is preferred (e.g. http://ms.mcmaster.ca/lovric/1LS3/pdfs/ebola_model_paper.pdf ) over asking questions on twitter based on 2 data points.

@2closetocall: @cbkiyanda and ironically, by asking on Twitter somebody provides me with that…

@2closetocall: @cbkiyanda also, these rates still show that two nurses being infected while taking crazy precautions was unlikely it seems

@cbkiyanda: @2closetocall: need contact w/ vomit, blood, feces.  RT @NateSilver538: No, you didn’t catch Ebola on the subway. http://nyti.ms/1wnCzjz

@cbkiyanda: @2closetocall : hence, while they take more precautions, med. staff are also much more likely to come in contact with blood, vomit, feces.

@2closetocall: @cbkiyanda I know all this obviously. I still think you’re missing my point. But thanks anyway

@cbkiyanda: @2closetocall I feel you’re missing mine. Lower likelihood of infection given precaution, comes with increase in likelihood due to task.

I’m not sure I’m so enamored with twitter as a discussion platform, so I figured I’d go back over what I view as the underlying problem in his argument in more than 140 characters. Continue reading How surprising is it actually that nurses were infected with Ebola in Texas?

On grading essays (and procrastination)

If you don’t read tomorrow’s professor mailing list yet, I encourage you to do so. Post 1360 looks at grading (essays specifically, but also just grading in general). The posting ends with sound advice that can be applied probably very generally:

1. Work in moderation, a little bit each day, rather than procrastinating and bingeing.
2. Remain fresh and alert by taking breaks when needed.
3. Practise going a bit faster while maintaining quality.
4. Aim to do what’s good enough, not at perfection.
5. Redesign the task to make it more interesting.

A vs. An

If you’re a non-native English speaker you might have struggled about when to use a vs. an. A previous adviser of mine, after years of corrections, finally managed to make me internalize the basic rule:

If the following word starts with a vowel, use an. If the following word starts with a consonant, use a.

That’s not the actual rule though. The actual rule is

If the following word starts with a vowel sound, use an. If the following word starts with a consonant sound, use a.

You’re confused? Good. Thank Purdue for the easily accessible answer.

My guess is you had to scroll right

An article on La Presse (in french) reports on a study during which researchers asked participants to place Ukraine on a map. If you don’t read french it’s ok, just look at this picture.

carte_ukrain_originalThe original picture looks like this. My first thought, when looking at this image, is “What’s so bizarre in Eurasia that one just stops clicking right of India?” If you don’t see it, look at this updated version with a line, below.

Let’s do a little detective work. The original image size is 1540 pixels wide by 1025 pixels high, or an aspect ratio of roughly 1.5. That corresponds to an aspect ratio of 4.5:3,  13.5:9, or 15:10. None of which sound familiar. My red line is about 1120 pixels from the left edge. 1120:1025 is really close to 1:1 (it’s 1.09:1). My guess is the map was shown within a square box, centered around Greenwich for longitude. There may have been 95 pixels cut from the left side (basically Alaska).

carte_ukraine_with_barThe take home message is that such an error (if I’m right) would have been easily fixable. (I’m also trying to figure out which data was used to make the outline of the continents, but I can’t tell. Both google and openstreetmap show the great lakes at very low zoom settings.)
