Saint DA, Horton D, Yool A, Elliott A. A progressive assessment strategy improves student learning and perceived course quality in undergraduate physiology. Adv Physiol Educ 39: 218–222, 2015; doi:10.1152/advan.00004.2015.—In 2010, second-year physiology (n 165) had a traditional single 3-h end-of-semester exam. To provide diagnostic feedback earlier, for students enrolled in 2011 (n 128), we i...

BACKGROUND Analysis of clinical studies often necessitates multiple graphical representations of the results. Many professional software packages are available for this purpose. Most packages are either only commercially available or hard to use especially if one aims to generate or customize a huge number of similar graphical outputs. We developed a new, freely available software tool called K...

A three-dimensional thermo-mechanical model is developed for the transient contact between a thermal flying height control (TFC) slider and a disk asperity. The effect of contact conditions is investigated, including the friction coefficient and the circumferential disk velocity. The damage of the read–write shields due to contacts with disk asperities is studied along with the maximum temperat...

Web-based questions for assessment and self-assessment of students’ knowledge are important components of modern E-Learning. Parameterized questions allow to enhance the value of Web-based questions while also decreasing the authoring costs. This paper discusses the problems of implementation and evaluation of online parameterized questions for the domain of object-oriented programming. We pres...

Four classes of the same Industrial Organization class were compared. The test group was taught by the instructor dressed in business attire, while the comparison group was taught by the instructor dressed casually. Results show that the attendance for test students was 8.50 percentage points higher than comparison students and this increase is associated with an improvement in their final exam...

Although most schools offer and/or require a course in spreadsheet and database applications, the amount of meaningful learning derived from the class varies widely. The approach described in this paper involves a combination of demonstration and hands-on practice using two term-long cases to be used in an introductory course in spreadsheet and database applications. These cases, packaged toget...

Refunding efficiency, a measure of the optimality of a refunding decision, is widely used in the call exercise decision for agency, corporate, and municipal bonds. The original definition of efficiency assumes that the refunding bond is optionless. However, in practice, the refunding bond is often callable. We show that the commonly used method of incorporating the value of the refunding bond’s...
