My student experience with computer-based learning

General comparison of live vs. computer learning

Computer learning offers independence from time and place. One positive effect of time in­dependence, is that people have time to think before answering (or asking) questions.

In general, shy students are less shy on the net, than in a large auditorium.

At its best, personal contact is better live.

Netkursus.dk / Sitescape Forum / Paper text book

The course used Sitescape Forum which was not a teaching platform, it was a pure discussion tool. The material was an old-fashioned paperback textbook.

Student's questions were mostly answered by other students. The teacher could lean back, just ensuring that we didn't lead each other astray. (We didn't.) But - some students were clearly un­comfortable with answers that did not come from the teacher, with the teacher's authority.

Rosetta Stone

Rosetta Stone is a language learning tool that is al­most like a boring com­puter game. 'Boring' as in not very de­manding; as long as you use the sys­tem, you keep learn­ing. (Unlike most real class­rooms.)

In my situation - I understand Faroese very well, but dare not speak for fear of inflection errors - tools like Rosetta Stone seem ideal. Making mistakes to - and having them corrected by - a machine, is much less emotionally demanding than making mistakes in interaction with real people. (But Faroese is not one of the languages offered by Rosetta Stone.)

Linguaphone has moved from cassette tapes to the PC platform, but my impression is that they simply copied the material to a new platform, while Rosetta Stone created material that utilize new possibilities on the new platform.

edX


My edX experience is with hard topics (statistics, computer science) in a MOOC setting. MOOC implies that the only way to grade students, is through the answers they submit online. Which again puts limits on what can be said in the discussions. In my case, discussion simply did not start under those rules. I recently finished a course with 22000 students - I might as well have been alone.

Consistent with those rules, edX have isolated discussions on a separate page - not right below each exercise, which might have inspired more discussions.

In a blended learning environment, students may be graded on activities outside of edX, teachers may also have the capacity to look at how the discussions should influence the grades. (I do not yet know if a course designer can allow discussions below each exercise.)

For softer topics, I do not think that answering to a machine is a good idea. Often, your reasoning behind an answer is more important than the answer itself. I doubt if grading a soft-topic MOOC is a good idea.

edX made me take notes. In the old days, I did at most a few highlights and post-it notes in the textbook. But, with the material spread across several videos, labs and PDFs, I really needed to take notes to structure my material.

Live video lecture (demo)


I have attended a video lecture that demonstrated the concept. The lecture was not streamed nor available online, it was shown in a specific auditorium at a specific time.

A live lecture is bound to a specific point in time and space. The only gain in this case, was that the lecture was bound to another (and closer) point in space. But much was lost in terms of sound and video quality, and personal communication. It was so boring that I decided to sneak out, at that point, the guy sitting beside me was soundly asleep.

When moving from one platform to another, you will lose something. Make sure you also get the improvements made possible by the new platform.

A video lecture can and should be independent of time and space, I should be able to see it when and where I want. 

The edX video is much more than a broadcast

For edX videos, I can change the speed, I can stop when­ever I want, I can get sub­titles or a tran­script on screen, I can down­load the tran­script, and I can use the tran­script to start the video at a specific point.

Cerego

Cerego is a memorizing tool. 

If I really need to remember something, I think I will, even without Cerego. And if I don't need some factoid, I think Cerego will have a hard time teaching me. Still, I think it is a useful tool to memorize relevant material.
  • Causes of the Civil War
    Teaches some factoids about the Civil War, but nothing about its causes. On its own, it qualifies the students for quizzes and nothing more. But it is probably developed as a supplement to a history class.
  • Movie Quotes
    Hard to remember the cases where I know neither the movie nor the quote. Video clips might have helped. (Would that be 'fair use' copyrightwise?)
  • Russian Alphabet
    Works. But single letters is maybe not very inspiring. A useful addition for me might be the names of the Russian ships we see in Faroese waters.

Sitater fra Hareide

Hvis jeg skulle skrive en profil på Knut Arild Hareide i ei russeavis, ville det vært et vanskelig valg mellom følgende sitater:
  1. Når ble pingle negativt?
  2. Hallo jenter! Vil dokker ha juling?
Men om jeg visste han skulle bli formann i KrF, måtte jeg nok valgt nummer to.

Ettersom dette er internett, er jeg visst skyldig å komme med konteksten: Begge sitatene er fra Nytt på Nytt. Nr.2 sammenligner Tyrkias nedskyting av et russisk fly, med at unge Hareide går inn i klubblokalene til Bandidos og truer dem med juling.

"Spleiselag"






Spleiselag er et begrep som brukes for å få gjennomført samfunnsmessig ulønnsomme prosjekter. 

La oss si at prosjektet koster 1 000 000, men den samfunnsmessige verdien er bare 800 000. Vi inviterer institusjonene A og B til spleiselag. For A blir så spørsmålet om de vil spandere 500 000 på noe som er verdt 800 000, og svaret er ja. Den samme vurderingen gjør B.

Og summen av det hele er at samfunnet som helhet spanderer 1 000 000 på noe som bare er verdt 800 000.

Ovnsbakt steinbit

Jeg hadde et bokmerke til https://ultra.no/Fisk-og-skalldyr/Oppskrifter-fisk/Hvit-fisk/Ovnsbakt-steinbit/ men meny.no har kjøpt og ødelagt lenken.

Originalen skal være fra http://godfisk.no/, men jeg finner den ikke der.

Update: Jeg fant en kopi på https://jacobs.no/Fisk-og-skalldyr/Oppskrifter-fisk/Hvit-fisk/Ovnsbakt-steinbit/

Takket være Google cache har jeg oppskriften her:

Ingredienser

800grsteinbitfilet
2sssitronsaft
1løk i tynne skiver
2epler i terninger
250grsjampinjong i tynne skiver
1ssfrisk hakket timian eller 1 ts tørket
1,5dleplejuice
2sssmør
salt og pepper
Tilbehør
kokte poteter, ris eller pasta

Slik gjør du


Sett stekeovnen på 180 grader. Skjær fisken i serveringsbiter og legg dem i en smurt ildfast form. Drypp sitronsaft over fisken og dryss salt og pepper over. Stek fisken i ovn ca 12 minutter ved 180 grader. Surr løk og sjampinjong i smør til løken er myk. Tilsett epleterningene sammen med ev. tørket timian og surr videre til eplene så vidt er møre. Tilsett eplejuice og ev. frisk timian og smak til med salt og pepper.

Kayak Coffee

Inspired by Bulletproof Coffee, lactose intolerance, nutritional needs while kayaking, and the fact that peanuts taste good with coffee, here is the recipe for Kayak Coffee:
Kayak coffee
  • Rinse the filter paper with boiling water
  • Use the water to pre-heat a blender and a 0.5 l vacuum flask
  • Brew strong coffee from 500g water and 45g coffee (15s on my Bodum grinder) into the blender
  • Add 25g black syrup
  • Add 25g peanut butter
  • Blend it thoroughly
  • Pour into the vacuum flask
  • Go kayaking
  • Take a break
  • Shake the vacuum flask
  • Serve
  • Enjoy
The peanut butter in my initial test contained 0.7% salt. That didn't seem to matter, we probably got more than that from the salty ocean environment.

Maybe the syrup and nuts dosage can be increased. But if your are not enjoying a break from physical activity, drop the syrup.

Optional: If all guest tolerate lactose, add two teaspoons of whey protein powder.

Er skummet melk sunt?

En liter skummet melk inneholder 1400 kJ.

Den samme mengden energi får man fra 560 g helmelk, 359 g ymer(hvíta) eller 543 g skyr.

Så dosen med skummet melk inneholder nesten dobbelt så mye sukker som det nest søteste alternativet: Helmelk

g g fett g protein g sukker
skummet melk 1000 1 33 46
helmelk 560 17 18 26
ymer/hvíta 359 14 27 14
skyr 543 1 60 20

Sammenligning per liter gir et annet resultat. Men hverken melk, jus eller øl skal drikkes som tørste­slukkere.

The etymology of Rock and Roll

Kenneth Williamson, Faroe Islands, 1941:

"The stupid whales […] in water too shallow for swimming they rocked and rolled without control"
