I’ve been wondering how scalable either my ELementary Engineering Curriculum or any other similar program would be in terms of cost per student. So if we assume 24 kids per class, kids working in pairs, teachers sharing the kits by quarters, schools with 1, 2, 3, or 4 classes per grade, and BeeBot at K, Lego WeDo at grades 1 to 4, and Lego NXT at grades 5 and 6, we get the following results.
1 Class Per Grade $37/student $6232
2 Classes Per Grade $23/student $7672
3 Classes Per Grade $25/student $12,664
4 Classes Per Grade $21/student $13,804
Some configurations result in a better cost efficiencies since the kits are more fully utilized. This only includes the cost of the robotics and does not include professional development or associated laptops.
