    Imagine you are floating in space on a huge NASA spacecraft. A satellite is on a collision course with your spaceship. You have just been told by your commanders on Earth to evacuate. You and your teammates have to make rapid decisions for your escape and survival.

Engaging children in a NASA mission (任务) is a lesson that 23 pre-service teachers (职前教师)were taught to carry out at a recent Pre-Service Teacher Institute (PSTI) summer workshop (讲习班)at NASA’s Ames Research Center.

At this two-week workshop, these college students were given hands-on activities designed to increase their skills in teaching STEM (science, technology, engineering and math) . They were shown how to include NASA missions and research into their lesson plans. They met with NASA engineers and were given tours of NASA facilities (设施)by the latter to help them develop and teach a problem-based lesson to children.

“NASA is pleased to support college students who want to teach STEM to young children,” said Lewis Braxton, director of the research center. “It was exciting to see PSII students fully engaged in developing new skills in STEM to meet the challenges of a space-related teaching task,” said Steve Price, the principal investigator of PSTI at California State University, Fresno.

“PSTI has provided me with the necessary tools and techniques to fully develop my skills as a teacher. I’ll use what I’ve learned to help my students succeed in their studies,” said Elijah Carnillo, one of the pre-service teachers.
