How do NASA, STEM, and PBL meet the needs of 21st century education?

NASA, STEM, and PBL offer us the tools to meet the needs of 21st centyury education.  The biggest take home message for me has been to teach problem-solving and inquiry skills.  It was very helpful to read through tips on creating a STEM lesson.  My next step is to take a lesson I currently teach and see how I can adapt it within these guidelines.   I am excited that this fits together with my use of technlogy in the classroom.  I will be able to grow in that as well.
