Femtosecond laser micromachining, at KAIST (Daedeok Innopolis, Daejeon, South Korea), Thursday, January 12, 2012:
talk_1852.pdf
When femtosecond laser pulses are focused tightly into a transparent material, the intensity in the focal volume can become high enough to cause nonlinear absorption of laser energy. The absorption, in turn, can lead to permanent structural or chemical changes. Such changes can be used for micromachining bulk transparent materials. Applications include data storage and the writing of waveguides and waveguide splitters in bulk glass, fabrication of micromechanical devices in polymers, and subcellular photodisruption inside single cells.
Peer Instruction, at Science Education Colloquium, Korea National University of Education (Cheongwon, North Chungcheong, South Korea), Thursday, January 12, 2012:
talk_1851.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 2-hour long workshop, participants will learn about Peer Instruction, serve as the "class" in which Peer Instruction is... Read more about Peer Instruction
Memorization or understanding: are we teaching the right thing?, at Science Education Colloquium, Korea National University of Education (Cheongwon, North Chungcheong, South Korea), Wednesday, January 11, 2012:
talk_1850.pdf
Education is more than just transfer of information, yet that is what is mostly done in large introductory courses -- instructors present material (even though this material might be readily available in printed form) and for students the main purpose of lectures is to take down as many notes as they can. Few students have the ability, motivation, and discipline to synthesize all the information delivered to them. Yet synthesis is perhaps the most important -- and most elusive -- aspect of education. I will show how shifting the focus in lectures from delivering information to synthesizing... Read more about Memorization or understanding: are we teaching the right thing?

Nonlinear optics at the nanoscale, at Chemistry Colloquium, Seoul National University (Seoul, South Korea), Monday, January 9, 2012:
talk_1847.pdf
We explore nonlinear optical phenomena at the nanoscale by launching femtosecond laser pulses into long silica nanowires. Using evanescent coupling between wires we demonstrate a number of nanophotonic devices. At high intensity the nanowires produce a strong supercontinuum over short interaction lengths (less than 20 mm) and at a very low energy threshold (about 1 nJ), making them ideal sources of coherent white-light for nanophotonic applications. The spectral broadening reveals an optimal fiber diameter to enhance nonlinear effects with minimal dispersion. We also present a device that... Read more about Nonlinear optics at the nanoscale

Engaging students one-on-one, all at once; Session 1, at LASPAU/IDIA Short Online Course for the Universidad de los Andes (Chile) (Cambridge, MA), Thursday, January 5, 2012:
talk_1832.pdf
This short-course introduces participants to the ideas of Peer Instruction (PI) and Just- in-Time-Teaching (JiTT), two research-based methods for engaging students, improving conceptual understanding, increasing retention in courses and programs, and enhancing academic performance. Participants will also learn about a new approach to instructional design. Finally, participants will apply the knowledge gained to a specific course module they are (or will be) teaching, by re-designing (or designing) the syllabus for this course module and developing a plan for implementing PI and JiTT. The... Read more about Engaging students one-on-one, all at once; Session 1
