As interest in acquiring programming skills continue to increase, many are turning to discretionary online resources to learn programming. However, researchers and educators need more data to better understand who these learners are and what their needs are to create useful and sustainable learning technologies to support them. In my work, I investigate the factors that make a learning game engaging...
Although there are many systems designed to engage people in programming, few explicitly teach the subject, expecting learners to acquire the necessary skills on their own as they create programs from scratch. We present a principled approach to teach programming using a debugging game called Gidget, which was created using a unique set of seven design principles. A total of 44 teens played it via...
A large size chamber with 450 mm and plasma wall-interaction for the nano-scale feature are needed in semiconductor manufacturing industry recently. However, there are difficulties to experiment and simulate a large scale reactor chamber and nano-scale features. In the simulation case, plasma simulation using particle-in-cell (PIC) method shows very high accuracy compared with fluid simulations. However,...
We have investigated the basic plasma density and electron tempereature by using the collisional radiative model, and also investigated the reactive radical species's densities for hydroxyl OH, superoxide anion O2*− and nitric oxide NO by using the ultravilioet absorption spectroscopy with the deuterium lamp in the atmospheric pressure nonthermal argon bioplasma sources bombarding the water surface...
Support requests are a major source of feedback in software development. However, like sentences whispered in a children's telephone game, as an issue moves through a software development process, it may undergo many changes, making it difficult to ensure that the problem reported was actually fixed. To better understand how software teams preserve the integrity of user-reported issues, we observed...
It is a global trend that those engineers who are proficient with the principles of business and management are rewarded with leadership roles. With the growing interdependence between technology, industry, economy and society, more opportunities will be available for engineers to exercise their potential as leaders, not only in business but also in the nonprofit and government sectors. In this paper,...
