What was used in the worst school massacre (killed 38 elementary school children),?

Sorry but you're missing the point

The day a strong centralized federal government left the confines of Washington DC, the Constitution; entered into the classrooms where children are being taught and began dictating how the young are educated, is by far the most tragic day for education.

According to your link, dynamite and a 30-30 as a detonator. So, what is your point? Are you disappointed guns did not manage a higher body count or what?

Actually a rifle was used there too. He shot the explosives (pyrotol) to detonate it.

What happened? Pyrotol the explosive he used was banned the following year in 1928.

You may have made the opposite point of what you were trying to make.

What if 20 children died in a school bus accident -- would CNN and FOX milk their dead bodies for ratings?

1926 this fruit loop blew up the school. No guns involved, Just good ole dynomite,
