Educating: One on one, all at once, at 60th Reunion, Harvard University (Cambridge, MA), Wednesday, May 27, 2015:
talk_2489.pdf
I thought I was a good teacher until I discovered my students were just memorizing information rather than learning to understand the material. Who was to blame? The students? The material? I will explain how I came to the agonizing conclusion that the culprit was neither of these. It was my teaching that caused students to fail! I will show how I have adjusted my approach to teaching and how it has improved my students' performance significantly
Educating the Innovators of the 21st Century, at Chulalongkorn University (Bangkok, Thailand), Monday, May 25, 2015:
talk_2464.pdf
Can we teach innovation? Innovation requires whole-brain thinking — right-brain thinking for creativity and imagination, and left-brain thinking for planning and execution. Our current approach to education in science and technology, focuses on the transfer of information, developing mostly right-brain thinking by stressing copying and reproducing existing ideas rather than generating new ones. I will show how shifting the focus in lectures from delivering information to team work and creative thinking greatly improves the learning that takes place in the classroom and promotes independent...

Black silicon and the quest for intermediate band semiconductors, at Siam Physics Congress 2015 (Krabi, Thailand), Thursday, May 21, 2015:
talk_2462.pdf
Shining intense, ultrashort laser pulses on the surface of a crystalline silicon wafer drastically changes the optical, material and electronic properties of the wafer. The resulting textured surface is highly absorbing and looks black to the eye. The properties of this 'black silicon' make it useful for a wide range of commercial devices. In particular, we have been able to fabricate highly-sensitive PIN photodetectors using this material. The sensitivity extends to wavelengths of 1600 nm making them particularly useful for applications in communications and remote sensing.
Teaching Physics, Conservation Laws First, at Siam Physics Congress 2015 (Krabi, Thailand), Thursday, May 21, 2015:
talk_2485.pdf
The Principles and Practice of Physics is a groundbreaking new calculus-based introductory physics textbook that uses a unique organization and pedagogy to allow students to develop a true conceptual understanding of physics alongside the quantitative skills needed in the course. The book organizes introductory physics around the conservation principles and provides a unified contemporary view of introductory physics. In this talk we will discuss the unique architecture of the book, the conservation-laws-first approach, and results obtained with this book.
Assessment: The silent killer of learning, at Siam Physics Congress 2015 (Krabi, Thailand), Wednesday, May 20, 2015:
talk_2461.pdf
Why is it that stellar students sometimes fail in the workplace while dropouts succeed? One reason is that most, if not all, of our current assessment practices are inauthentic. Just as the lecture focuses on the delivery of information to students, so does assessment often focus on having students regurgitate that same information back to the instructor. Consequently, assessment fails to focus on the skills that are relevant in life in the 21st century. Assessment has been called the "hidden curriculum" as it is an important driver of students' study habits. Unless we rethink our approach to...

Peer Instruction, at Brigham Young University - Idaho (Rexburg, ID), Friday, May 15, 2015:
talk_2407.pdf
The basic goals of Peer Instruction are to encourage and make use of student interaction during lectures, while focusing students' attention on underlying concepts and techniques. The method has been assessed in many studies using standardized, diagnostic tests and shown to be considerably more effective than the conventional lecture approach to teaching. Peer Instruction is now used in a wide range of science and math courses at the college and secondary level. In this workshop, participants will learn about Peer Instruction, serve as the "class" in which Peer Instruction is demonstrated,... Read more about Peer Instruction
Flat space, deep learning, at Brigham Young University - Idaho (Rexburg, ID), Friday, May 15, 2015:
talk_2405.pdf
The teaching of physics to engineering students has remained stagnant for close to a century. In this novel team-based, project-based approach, we break the mold by giving students ownership of their learning. This new course has no standard lectures or exams, yet students’ conceptual gains are significantly greater than those obtained in traditional courses. The course blends six best practices to deliver a learning experience that helps students develop important skills, including communication, estimation, problem solving, and team skills, in addition to a solid conceptual understanding...

How student learning transformed my teaching, at Brigham Young University - Idaho (Rexburg, ID), Friday, May 15, 2015:
