       | This is a good article. Dan Meyer, like his PhD supervisor Jo
       | Boaler, is very much in the camp that traditional classroom
       | education is good, and that improvements come by working through
       | school districts, administrators and classroom teachers.
       | 
       | I'm not saying this to cast doubt on any of the facts in the
       | article. Just pointing out that Dan, in general, has a less
       | optimistic view of AI in education, than I'd expect of the median
       | HN commenter.
       | 
       | That said, I'll share my thoughts on Alpha School, based on
       | everything I've read (both things published by the school, and
       | things I've read from parents online and in private forums):
       | 
       | - the '2x growth' in their marketing is way oversold; their
       | typical 4th grader isn't doing math at the level of a typical 8th
       | grader.[0]
       | 
       | - the '2 hours/day' in their marketing is oversold; students
       | often work longer than that.
       | 
       | - only 25% of their students use Math Academy. The rest use IXL
       | or ALEKS.
       | 
       | - in their charter school application, the amount they proposed
       | charging for their software platform was unreasonable, given the
       | minor role it plays in outcomes (10% according to Matt Bateman,
       | who works there) [1]
       | 
       | - the core idea of their 'timeback' platform (that monitors
       | student activity in realtime via video camera and screen
       | recording) is good, but I have not seen it and have no idea
       | whether it's real or how good it is
       | 
       | More of my thoughts from back in April:

         | The intellectual pedigree actually explains everything. Jo
         | Boaler is the one responsible for charging $5k/hr to advise
         | schools to end middle school algebra. In an amusing confluence
         | of concepts, Garry Tan (CEO of YC - whose site we're on)
         | describes her as "infamous and disgraced"[0].
         | 
         | I don't know about that, but when I discovered that San
         | Francisco schools weren't teaching algebra I was at first
         | impressed that American children were doing Group Theory in 8th
         | grade (something we only learn in the 12th standard in Tamil
         | Nadu in India where I'm from) and figured moving that to 9th
         | isn't a big deal only to find that they meant the basic stuff
         | (linear equations and the like, what we learn in the 7th
         | grade).
         | 
         | Honestly, I can't take anyone seriously who would try so hard
         | to set back children from learning what is fairly basic
         | Mathematics at that age. Children are capable of learning this.
         | Or at least a sufficiently large amount are that we should be
         | teaching them to a high standard.
         | 
         | For Alpha School, I think the Slate Star Codex review is likely
         | more informative than this clearly polemic article.

         | tl;dr This is from the people who want to delay Mathematics
         | education to later in a child's life (algebra to 9th grade
         | onwards)

         | Kids have always been low attention span. Things are probably
         | better than before because we have ADHD treatments that work
         | that we just ignored in the past. Blaming tech is just the
         | latest thing, but you can always find parents blaming low
         | attention span on whatever the latest fad to blame it on is.
         | Truth is kids are not really "designed" to sit in a classroom
         | for hours every day - but it is still the best way we have to
         | set them up for a modern life so we force it anyway.
