Connecting Self-Efficacy And Nature Of Science Shifts In Undergraduate Research Experiences, Gina Quan
Connecting Self-Efficacy And Nature Of Science Shifts In Undergraduate Research Experiences, Gina Quan
Faculty Publications
Undergraduate research can support students’ more central participation in physics. We present analysis of one way this participation may shift: changes in their beliefs about the Nature of Science coupled to changes in a sense of ability to contribute to authentic research. Students in the study worked with faculty and graduate student research mentors on research projects and also participated in a seminar where they learned about research and reflected on their experiences. In videotaped interviews, we asked students to describe their experiences in research. Students developed nuanced views about how the research process works coupled to shifts in their …
Tensions In The Productivity In Design Task Tinkering – Fundamental, Gina Quan, Ayush Gupta
Tensions In The Productivity In Design Task Tinkering – Fundamental, Gina Quan, Ayush Gupta
Faculty Publications
Tensions in the Productivity in Design Task TinkeringTinkering is an ad-hoc approach to a problem and involves the practice of manipulating objectsto characterize and build knowledge about a particular system in an exploratory way, often withthe goal of getting some product/idea to produce desired behavior (e.g. Turkle & Papert, 1991;Berland, 2013; Roth, 1996). Tinkering thus contrasts with more deliberate activity towardsunderstanding how some phenomenon works or towards achieving conceptual understanding.Some researchers have argued that tinkering is an unproductive process because it does notalways lead to progress and/or conceptual learning (Law, 1998; Yeshno & Ben-Ari, 2001).Others view it as productive for …

This report documents a research effort to understand the current practice and issues associated with Bus Rapid Transit (BRT) planning and deployment. It reviewed the design options incorporated into existing BRT deployments across California and the nation. The project team interviewed practitioners of California Department of Transportation (Caltrans) Districts and transit agencies to understand the BRT project approval decision-making process, the impacts of BRT implementation and the Measures of Effectiveness (MOEs) for transit and non-transit system performance. The studies revealed that though Caltrans and transit agencies do use a similar set of MOEs for the evaluation of BRT projects, the …
A General Intuitive Design Pattern For Optimally Sequencing Treatment Combinations In 2k Factorial Experiment And A Simple Estimation Algorithm, H.-S. Jacob Tsao, Minnie Patel
A General Intuitive Design Pattern For Optimally Sequencing Treatment Combinations In 2k Factorial Experiment And A Simple Estimation Algorithm, H.-S. Jacob Tsao, Minnie Patel
Faculty Publications
The number of model parameters of a 2k factorial design grows exponentially. When the number of factors is large, numerous higher-order interactions constitute a vast majority of the model parameters while many of them do not exist or are insignificant. The classic methods of fractional factorial designs, Plackett–Burman designs, Taguchi designs, etc. seek an already developed and often cataloged design that fits exactly the problem being tackled or select a design that fits it the most. Most, if not all, of these designs were developed in absence of convenient computation tools and enjoy computational simplicity. The necessary number of treatment …
A Human-Centered Credit-Banking System For Convenient, Fair And Secure Carpooling Among Members Of An Association, H.-S. Jacob Tsao, Magdalini Eirinaki
A Human-Centered Credit-Banking System For Convenient, Fair And Secure Carpooling Among Members Of An Association, H.-S. Jacob Tsao, Magdalini Eirinaki
Faculty Publications
This paper proposes an unconventional carpool-matching system concept that is different from existing systems with four innovative operational features: (F1) The proposed matching system will be used by members of an association and sponsored by the association, e.g., the employees of a company, members of a homeowner association, employees of a shopping center. This expands the scope beyond commute trips. Such associations can also voluntarily form alliances to increase the number of possible carpool partners and geographical reach. (F2) Service provided by a driver or received by a rider incurs credit or debt to a bank centrally and fairly managed …
