If there’s one lesson I take from them, it is less class time. I wrote recently about how I’ve and heard of football coaches (like college national champion) holding shorter practices and getting more intense learning in that time. I’ve been in charters where the school day stretched from 7:45am to 4:45pm, and you’re just wearing students out. Real, intense learning is exhausting and we should try to make that time/energy/space sacred. I genuinely think my students’ performance would increase with more time for physical activity, art, theater, music, and even study hall (or a shorter school day).

On the flip side, the downsides of Alpha’s intense motivational mode are broadly documented. I read (and wrote about) Alfie Kohn’s “Punished by Rewards” recently, and I would predict some burnout or reduced post-secondary performance from Alpha’s students with pretty high confidence.

Two thoughts:

1- a lot of the "it's all selection effect" stuff misses that the school not only has kids scoring in the top 1% in absolute terms (which could absolutely be selection effect), but that the kids at every level of performance improve FASTER (2-4x faster) than kids at similar levels of performance every three months.

For example, my daughter was 97th percentile in math in the fall (213). The average kid who was 97th percentile in the fall got to a score of 220 (+7) in the winter (kids at the top end of the scale improve faster than the average 50-percentile kid). Most kids, by definition, stay at roughly the same percentile they were at in the pervious period. But at Alpha the average kid is improving more than 2x that of a kid at the same percentile.

My daughter's winter MAP score was 230 (+17). That now puts her above the 99th percentile, and more than 2x the improvement of other 97th-percentile kids from the fall.

Selection effect could have put her in the 97th percentile, but it would not cause her to improve at 2x the rate of other 97th percentile kids.

2- On Timeback not being more effective than Dash (the old program).

It's possible there are no numbers to support it, but having seen the two programs it is very obvious Timeback is better. We decided to spend three months this winter in Spain, and Alpha wanted us to move back to Dash because it was easier for them to support remotely. I pushed back HARD. I asked my kids too and they freaked out at the idea of going back to Dash. Timeback has buggy issues, but it is clearly much much better than Dash.

Possible reason that the numbers for Timeback are not better than Dash:

- Diminishing returns. IT is a lot easier to take a kid at the 50th percentile and have them improve 2-10x faster than other kids at the 50th percentile. But taking kids at the 99th percentile and trying to get them to improve 2-10x is a lot harder. As Alpha moves more kids into the top percentiles, their acceleration stats are going to drop. The fact they haven't dropped yet is partially because they are adding a lot of students (And many come in at the lower percentiles), and MAYBE because Timeback is better than Dash

- Timeback is new. Kids have only been using it since August at the earliest. So this is the first "cycle" of improvements. It could just be noise

- It is also BUGGY. They fix the bugs as they come up, but it is the reason it's not available for remote use. That could be causing distrations that make learning less efficient and make up for the other gains.

If nothing else I recommend trying ixl math and then trying math academy. If you think the two programs have the same learning effectiveness I will be very surprised.
