    High Throughput Poration of Mammalian Cells using Femtosecond Laser-activated Plasmonic Substrates, at Tokyo Metropolitan University (Tokyo, Japan), Thursday, January 29, 2015:
    talk_2425.pdf
    We present a new cell transfection method that uses femtosecond laser-excited localized surface plasmons (LSPs) on a nanostructured micropyramid array. Our gold-layered micropyramids have nano-apertures at the apex to form high local electric field enhancements, or “hot spots.” These hot spots form microbubbles that temporarily perforate mammalian cell (HeLa S3) membranes and allow dye molecules and plasmid vectors to diffuse through the membrane openings. We optimize our laser parameters for successful poration and high cell viability. Our nontoxic, efficient, and scalable technique...

    The Principles and Practice of Physics, at Webinar (Cambride, MA), Monday, February 9, 2015:
    talk_2416.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 Hope College (Holland, MI), Friday, February 13, 2015:
    talk_2393.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...

    Confessions of a converted lecturer, at University of Florida (Gainesville, FL), Monday, February 16, 2015:
    talk_2417.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

    Nonlinear optics at the nanoscale, at University of Florida (Gainesville, FL), Monday, February 16, 2015:
    talk_2398.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

    Catalyzing Learning using Learning Catalytics, at University of Utah (Salt Lake City, UT), Monday, March 2, 2015:
    talk_2427.pdf
    Most -- if not all -- of the important skills in our life are acquired outside the traditional classroom setting. Yet we continue to teach using lectures where students passively take down information. Instead, we should really focus on the assimilation of that information and shift the focus from teaching to helping students learn. Over the past 20 years, instructors world-wide have begun to adopt Peer Instruction to get students to think in class. With the advent of new technology the process can be significantly improved. A new data-analytics driven audience response system does away with... Read more about Catalyzing Learning using Learning Catalytics

    Effective teaching and how to engage students in the classroom, at Utah Valley University (Orem, UT), Wednesday, March 4, 2015:
    talk_2430.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 Effective teaching and how to engage students in the classroom

    Flat space, deep learning, at Annual Meeting of the Team-based Learning Collaborative (St. Petersburg, FL), Friday, March 6, 2015:
    talk_2364.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...
