Figure 1: Conventional non-shingled writing, on the left, writes data in non-overlapping tracks, width w, with non-magnetized “guard regions”, width g, between tracks. Shingled writing, on the right, leaves residual tracks, width r, less than the width of the written track, width w’, before it writes the next track, largely overlapping adjacent tracks. This increases tracks per inch, increasing...

Introduction All-terrain vehicles (ATVs) are associated with injury, mortality, and healthcare costs. ATV related injuries are less severe when consistent safety practices are followed, however, ATV safety regulations are varied among states. This study sought to survey Kansas ATV dealers and track owners to determine safety promotion practices. Methods A cross-sectional telephone survey was ...

Researchers have extensively studied phenomena that affect a second language learner’s oral production while there is scant evidence about input-related factors. Accordingly, the present study sought to investigate how variation in oral production is caused by the input they receive from different course materials. To this end, the study included a micro-evaluation study of three course materia...

In a series of 5 experiments in 2000 and 2001, several hundred students at two different universities with three different professors and six different teaching assistants took a semester long course on causal and statistical reasoning in either traditional lecture/recitation or online/recitation format. In this paper we compare the pre-post test gains of these students, we identify features of...

SESSION VI: Animal Models Joseph Buxbaum July 23, 2015 // 12:00 pm EST Course Materials The purpose of these materials is to help provide an introduction to the Summer Institute session on animal models. The materials were designed to prepare trainees who are unfamiliar with research using animal models with the general background to get the most educational benefit from Dr. Buxbaum’s presenta...

The introductory materials science and engineering course offered at the college/university level is, for many instructors, very difficult to design and to teach. This presentation discusses challenges for the course, as well as several problematic issues to include: course content, course organization, and course mechanics. The results of two surveys of engineering faculty are presented and di...

Computer-based learning materials eventually forming an entire online course in Statics are presented. The course, developed as part of the Carnegie Mellon Open Learning Initiative (OLI) and available to individual learners and institutions, draws upon the authors’ ongoing work to reorganize Statics instruction to better address the conceptual challenges students face. Comprising approximately ...
