Lego also recognized that it had to build a course that'll work regardless of a teacher's fluency in such subjects. So a big part of developing the course was making sure that teachers had the tools they needed to be on top of whatever lessons they're working on. "When we design and we test the products, we're not the ones testing in the classroom," Silwinski said. "We give it to a teacher and we provide all of the lesson materials, all of the training, all of the notes, all the presentation materials, everything that they need to be able to teach the lesson." Lego also took into account the fact that some schools might introduce its students to these things starting in Kindergarten, whereas others might skip to the grade 3-5 or 6-8 sets.

STEM has a bit of an image problem: Despite efforts to make it colorful and friendly, it's still intimidating to a lot of students. When there are parents shoving electronics kits at them while offering no help and teachers insisting that learning to code is fundamental to their future career prospects, some kids end up completely turned off. But now Lego Education has a new $330 kit, Spike Prime, aimed at building coding literacy and overcoming the confidence problem that drives many kids away from STEM before they reach high school. Instead of pointing students toward more complex projects, Spike Prime is about basic knowledge and practicality. As Esben Stærk Jørgensen, the president of Lego Education, said during a press event in New York today, Spike Prime is not about learning to code so much as it is coding to learn.
