Bad training of the astronauts led to the failure of the student experiments recently on ISS.

Bad training of the ISS astronauts by the company supplying the experiments was the reason the student experiments were never turned on.

“Previous crews were given on the ground review and personal interaction prior to launch,” Manber said. “For this mission, the astronaut received hardware training solely via video while on the space station. Clearly, there was a miscommunication resulting from the video instruction.”
