"Excitement about 3D printing has steadily accelerated over the past decade - but this excitement has largely outpaced innovation and development in the field. As a researcher in 3D printing technologies, I've built 3D printers using all of the major technologies, as well as more experimental ones. What I've learned is that many of these technologies are composed of very well-understood materials, software problems and mechanical systems - things that engineers have been doing for decades. This, then, begs the question: Why isn't 3D printing better? Why are failure rates so high and why is reproducibility so difficult? It's clear that it's not due to working with exotic materials or advanced motion control. What's actually holding back innovation is how we think about those technologies: as separate pieces, rather than as elements of a system. "

" TWEETSHAREEMAIL Over the summer, academics debated the impact of growth mindset, the belief that one's intelligence can be developed with hard work and effort, and whether it can move the needle on academic performance. Even Stanford psychology professor Carol Dweck, who is often credited with the term, chimed in with additional research supporting the efficacy of mindset interventions. An Education Week survey found that the vast majority of educators believe that a growth-oriented mindset can help improve students' motivation, commitment and engagement in learning. But the study found that applying those ideas to practice, and helping students shift their mindset around learning, remains an elusive challenge. Those findings largely coincide with my observations as an administrator, coach, technology implementer, and now founder of an education company. Over the summer, my team ran a series of professional learning community sessions with dozens of educators across the country, focused on instructional practices that foster and support growth mindset. At these events, almost all teachers said they get the big ideas around growth mindset, but over 80 percent said their schools don't implement them well."

"When teachers reexamine how they were taught math and their perceptions of their ability, student test scores and attitudes about math dramatically improve, according to a new study. The research, which appears in the journal Education Sciences, shows that fifth-grade teachers who took an online class designed to give them a different approach to mathematics teaching and learning, achieved significantly higher test results for their students compared with a control group of teachers in the same schools who did not take the class."

Really interesting categorization of today's learners being Digital Orphans, Digital Exiles or Digital Heirs.
