Black silicon and the quest for intermediate band semiconductors, at Laser-Based Micro and Nano Processing VIII, Photonics West 2014 (San Francisco, CA), Thursday, February 6, 2014:
talk_2198.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 process has two effects: it structures the surface and incorporate dopants into the sample to a concentration highly exceeding the equilibrium solubility limit. This femtosecond laser "hyperdoping technique" enables the fabrication of defect- and bandgap engineered semiconductors, and laser texturing further enhances the optical density through excellent light trapping. Hyperdoped silicon opens the door for novel... Read more about Black silicon and the quest for intermediate band semiconductors

Multidimensional Measurement in Education, at Harvard Physics Research Scholar Retreat (Charlestown, MA), Friday, October 18, 2013:
talk_2213.pdf
Many of the Mazur Group Education research projects focus on measurement. Four areas of current interest to the group are learning, metacognition, interaction, and self-efficacy. This talk outlines some of our projects that measure interaction between students in and out of the classroom.
Science outreach: too little, too late, at 10th Science and Technology in Society Forum (Kyoto, Japan), Monday, October 7, 2013:
talk_2128.pdf
The goal of science outreach should be continued fueling of the curiosity of the mind not the reawakening of it. In order to achieve that goal we need to re-think our approach to teaching and above all our approach to assessment in science.

Leveraging Technology to Enhance Evidence-Based Pedagogy: A Case Study of Peer Instruction in Norway, at Universidad del Norte (Barranquilla, Colombia), Friday, March 22, 2013:
talk_2104.pdf
Peer Instruction (PI) is an evidence-based, interactive teaching method developed by Eric Mazur at Harvard University in the 1990s. PI has been adopted across the disciplines, in every institutional type, and in classrooms throughout the world. A global community of innovative educators, the Peer Instruction Network connects users worldwide and provides opportunities for sharing and learning about PI. While PI can be implemented using basic classroom tools, it is enhanced when paired with educational technologies. In this presentation, PI expert and Peer Instruction Network co-founder, Dr....

Catalyzing Learner Engagement Using Cutting-Edge Classroom Response Systems in Higher Education, at 2013 International HETL Conference, University of Central Florida (Orlando, FL), Tuesday, January 15, 2013:
talk_2057.pdf
In this presentation, we introduce a cutting-edge technology for enacting and measuring learner engagement in novel ways. We will open by problematizing traditional approaches to learner engagement and offer a research-based solution in a new classroom response system developed at Harvard University—Learning Catalytics. The presentation will include an overview of key cognitive science principles tied to research on how students learn best. We will link those principles with the functionality of Learning Catalytics to connect learning theory to teaching practice. We will then provide an...
