Flash Calculation

A fast flash calculation of the Rachford-Rice equation is very much needed in many engineering applications, especially in multi-component mixtures. This paper suggests a direct and hands-on calculation by a pocket calculator or a Chinese abacus. The calculation is based on an ancient Chinese mathematics called as He Chengtian average. An example is given to show the simplicity and effectiveness of the ancient Chinese algorithm.

Hands On

We have designed an intensive, three-week robotics program for high school students that combines theory with hands-on practical experience in cutting edge technologies. Conventional approaches to engineering education are bottom-up. Students are first taught the basics and are then courses that build on the basics. Most students do not take coursework on engineering applications, particularly design and systems engineering, until the end of the curriculum. This has the disadvantage of not exposing students to the excitement in engineering until late in the curriculum. Our goal is to develop a top-down curriculum in which students are introduced first to the applications and systems concepts which then leads to the teaching of fundamentals. This approach has the potential to recruit and retain students in engineering while making the curriculum more relevant and rigorous.

Improve Instruction

The Materials Science Department at Iowa State University has developed a laboratory designed to improve instruction in the use of the scanning electron microscope (SEM). The laboratory makes use of a computer network and a series of remote workstations in a classroom setting to provide students with increased hands-on access to the SEM. The laboratory has also been equipped such that distance learning via the internet can be achieved.A view of the laboratory is shown in Figure 1. The laboratory consists of a JEOL 6100 SEM, a Macintosh Quadra computer that acts as a server for the network and controls the energy dispersive spectrometer (EDS), four Macintosh computers that act as remote workstations, and a fifth Macintosh that acts as an internet server. A schematic layout of the classroom is shown in Figure 2. The workstations are connected directly to the SEM to allow joystick and computer control of the microscope. An ethernet connection between the Quadra and the workstations allows students seated there to operate the EDS. Control of the microscope and joystick is passed between the workstations by a switch-box assembly that resides at the microscope console. When the switch-box assembly is activated a direct serial line is established between the specified workstation and the microscope via the SEM’s RS-232.

Teaching Learning

Promoting cultural competence in serving diverse clients has become critically important across disciplines. Yet, progress has been limited in raising awareness and sensitivity. Tervalon and Murray-Garcia (1998) believed that cultural competence can only be truly achieved through critical self-assessment, recognition of limits, and ongoing acquisition of knowledge (known as “cultural humility”). Teaching cultural humility, and the value associated with it remains a challenging task for many educators. Challenges inherent in such instruction stem from lack of resources/known strategies as well as learner and instructor readiness. Kirk (2007) further indicates that providing feedback on one's integrity could be threatening. In current study, both traditional classroom-based teaching pedagogy and hands-on community engagement were reviewed. To bridge a gap between academic teaching/learning and real world situations, the author proposed service learning as a means to teach cultural humility and empower students with confidence in serving clients from culturally/linguistically diverse backgrounds. To provide a class of 51 students with multicultural and multilingual community service experience, the author partnered with the Tzu-Chi Foundation (an international nonprofit organization). In this article, the results, strengths, and limitations of this service learning project are discussed.

Lack Of Knowledge

Telepractice, defined by the American Speech-Language-Hearing Association (ASHA, n.d.) as “the application of telecommunications technology to the delivery of professional services at a distance by linking clinician to client, or clinician to clinician, for assessment, intervention, and/or consultation,” is a quickly growing aspect of practicing audiology. However, only 12% of audiologists are involved in providing services via telepractice (REDA International, Inc., 2002). Lack of knowledge regarding telepractice has been cited as one of the reasons many audiologists do not use telepractice to provide audiology services. This study surveyed audiology doctoral students regarding their opinions about the use of telepractice both before and after their opportunity to provide services via telepractice sessions. The authors expected that by providing students the opportunity to have hands-on training in telepractice with supervision, they would be more open to using telepractice after becoming licensed audiologists. Overall, the data indicates benefits of exposing students to telepractice while they are in graduate school.
