Lens to Learning: Class-wide video analysis of Peer Instruction discussions, at AAPT Summer Meeting 2013 (Portland, OR), Wednesday, July 17, 2013:
talk_2214.pdf
Numerous studies show courses taught using Peer Instruction have higher learning gains than traditional courses on standardized assessments. Yet we have very few measurements of what actually happens during the peer discussion component of this pedagogy. To address this need, we recorded every student discussion in nearly every lecture of an introductory physics course at a major research university. We will present results from analysis of these student conversations, providing insight on discussion behavior over different questions. In addition, we will illustrate the interesting case of "...

Flipping Your Classroom With Peer Instruction: How To Turn Your Students' Worlds Right Side Up, at FlipCon13 (Stillwater, MN), Tuesday, June 18, 2013:
talk_2174.pdf
Instructors all over the globe are turning their students' worlds right side up by flipping their classrooms. In a flipped class, teachers typically move information coverage out of formal class meetings so that they can better leverage in-class time to address student difficulties or misconceptions. Flipped learning is much more than watching videos and doing homework in class. In this session, Dr. Julie Schell will introduce one research-based flipped method called Peer Instruction. A primary goal of Peer Instruction is to radically transform students’ in-class experiences. Originally...

The photovoltaic potential of femtosecond laser textured amorphous silicon, at Photonics West (San Francisco, CA), Thursday, February 7, 2013:
talk_2078.pdf
Femtosecond laser texturing of silicon yields nanometer scale surface roughness that reduces reflection and enhances light absorption. In this work, we study the potential of using this technique to improve efficiencies of amorphous silicon-based solar cells by laser texturing thin amorphous silicon films. We use Ti:Sapphire femtosecond laser systems to texture amorphous silicon in either hydrogen or sulfur hexafluoride ambient gases and we also study the effect of laser texturing the substrate before depositing amorphous silicon. We adjust the thin-film thickness and laser fabrication... Read more about The photovoltaic potential of femtosecond laser textured amorphous silicon
Formation of mixed metal oxides by femtosecond laser irradiation for solar harvesting, at SPIE Photonics West (San Francisco, CA), Tuesday, February 5, 2013
We present a novel method for producing mixed metal oxides using femtosecond laser doping of metallic foil in the presence of oxygen and another metallic dopant. We discuss doping titanium dioxide (TiO2) for above bandgap absorptance by irradiating titanium metal with an evaporated thin film of metal. As a wide bandgap, TiO2 most strongly absorbs in the UV range (?... Read more about Formation of mixed metal oxides by femtosecond laser irradiation for solar harvesting
Optimizing Anatase-TiO2 Deposition for Low-loss Waveguides, at Photonics West (San Francisco, CA), Tuesday, February 5, 2013:
talk_2083.pdf
Polycrystalline anatase-TiO2 thin film possesses desirable properties for on-chip photonic devices that can be used for optic computing, communication, and sensing. Low-loss anatase-TiO2 thin films are necessary for fabricating high quality optical devices. We studied anatase-TiO2 by reactively sputtering titanium metal in an oxygen environment and annealing. By correlating key deposition parameters, including oxygen flow rate, deposition pressure, RF power, and temperature to film morphology and planar waveguiding losses, we aim to understand the dominant source of propagation losses in TiO2...

Using Partnerships to Scale Innovation: UT-Austin’s OnRamps Initiative, at TASA Midwinter Conference (Austin, TX), Wednesday, January 30, 2013:
talk_2071.pdf
OnRamps is a statewide initiative organized by UT-Austin to accelerate students’ preparation for entry-level college courses. Three dual-credit courses are being developed by faculty at UT- Austin and other institutions for launch in fall 2013. This session focuses on how OnRamps has used strategic partnerships— with national experts, institutional and technological partners, and successful programs—to leverage expertise, as well as scale and support statewide innovation.
Using pedagogical innovation to improve student success in first-year courses, at 2013 International HETL Conference, University of Central Florida (Orlando, FL, USA), Monday, January 14, 2013:
talk_2058.pdf
Student retention is a higher education problem that penetrates diverse contexts, including institutional types, subject matter, and geographic region. Theories have historically linked increased retention rates to concepts such as campus involvement and institutional engagement (Tinto, 1993). Most higher education retention interventions thus focus on keeping students who are already at university, enrolled. Attrition is at its highest at the end of the first year of study (Tinto, 1993). One reason students drop out at this stage is because they are struggling academically in large,... Read more about Using pedagogical innovation to improve student success in first-year courses
Lens to Learning: Using Video Analysis to Classify Student Discussions During Peer Instruction, at American Association of Physics Teachers Winter Meeting 2013 (New Orleans, LA), Wednesday, January 9, 2013:
talk_2148.pdf
Numerous studies show courses taught using Peer Instruction have higher learning gains on standardized assessments. Yet we have very few measurements of what happens during the peer discussion component of this pedagogy. When students are told to discuss a physics question with a neighbor, do they do so? If so, do they have a substantive conversation about the physics, or just a brief exchange of answers? To address these questions, we recorded every student discussion in nearly every lecture of an introductory physics course at a major research university. Through both large-scale manual...
