| For example, Duolingo transformed into a tapping app where spaced
| repetition took a backseat and learners are incentivized to tap
| the same lesson until the badge tells them they know the lesson.
| The lessons are skewed towards the easier target->source
| questions because the population finds source->target too hard.
|
| So the app becomes extremely useless to me but I guess useful for
| the masses.

| On the other hand... there are other pressing bottlenecks to
| a Primer. Status quo has people learning the Sun is yellow,
| from Kindergarten teachers, college textbooks, and even
| outreach. With only a very very few of them getting an "oops,
| nope, our bad" correction years later in grad school,
| discussing common misconceptions in astronomy education.
| We're collectively not able, on a timescale of decades, to
| even get Sun color right in the most popular college
| textbooks. So if a Primer is to teach science and engineering
| as a richly interwoven coherent tapestry... we'll need to
| figure out socially how to transformatively improve our
| creation of those stories.
|
| The student in the video is learning the color lavender.
| Learning color is common preK-6. And yet, even first-tier
| physical-sciences graduate students are deeply steeped in
| misconceptions about color. So a motivational peer robot
| might help... at least with equity. But if we aspire to teach
| color _successfully_ , a novel goal, attention seems needed
| elsewhere. But there aren't great incentives to ask "What
| might a greenfield tech-enabled preK-6 _successful_ approach
| to teaching color look like? " Or at least, I've not seen it.
| If anyone knows of a setting for such questions, I'd greatly
| appreciate hearing of it.
