This study aims to contribute to empirical and interdisciplinary knowledge on how visual learning analytics tools can support students' cognitive engagement in complex in-class scenarios. Taking a holistic approach, instructional design, learning analytics, and students' perceptions were examined together. The teaching of systematic viewing and…

Accepting applicants with the highest probability of success is a priority for admission committees in institutions of higher education. For programs with limited capacity, selecting candidates with the greatest potential for successful completion of the program and becoming eligible for employment is crucial. Admission criteria that best predicts…

Nontraditional students have personal obstacles they must overcome in their journey through college. These barriers differ from traditional students and can include feelings of isolation and a sense that their chosen institutions are insensitive and inflexible to the particular nontraditional student needs. In this quantitative, causal-comparative…

To examine bone mass in children and adolescents with autism spectrum disorders (ASD). Risperidone-treated 5 to 17 year-old males underwent anthropometric and bone measurements, using dual-energy X-ray absorptiometry and peripheral quantitative computed tomography. Multivariable linear regression analysis models examined whether skeletal outcomes…

Visual expertise covers a broad range of types of studies and methodologies. Many studies incorporate some measure(s) of observer performance or how well participants perform on a given task. Receiver Operating Characteristic (ROC) analysis is a method commonly used in signal detection tasks (i.e., those in which the observer must decide whether…

Advances in three-dimensional (3D) printing allow for digital files to be turned into a "printed" physical product. For example, complex anatomical models derived from clinical or pre-clinical X-ray computed tomography (CT) data of patients or research specimens can be constructed using various printable materials. Although 3D printing…

This study compared bone mineral density (BMD) of the spine obtained by dual-energy X-ray absorptiometry (DEXA), nutritional status, biochemical markers, and gastrointestinal (GI) symptoms in 4-8 year old boys with Autism Spectrum Disorder (ASD) with a group of age-matched, healthy boys without ASD. Boys with ASD had significantly lower spine BMD…

The chest X-ray is the most commonly performed medical imaging study; however, the lateral chest film intimidates many physicians and medical students. The lateral view is more difficult to interpret than the frontal view but provides important information that is either not visible or not as evident on frontal view, and inability to read it may…

Reduced contact hours and access to cadaveric/prosection-based teaching in medical education has led to many doctors reporting inadequate anatomical knowledge of junior doctors. This trend poses significant risk, but perhaps most of all in surgery. Here the opinions of surgeons regarding current and future teaching practices in anatomy were…

The background of the study is that the planar film heterostructures are nowadays the most common objects nanophotonic and nanoelectronic technologies. The authors noted that, among such objects found so-called quantum wells, which are formed by a complex series of nanoscale layers are deposited with differing elemental composition, and simple…

This study looks at the practice of thoracic radiology and follows a group of radiologists and radiophysicists in their efforts to find, discuss, and formulate issues or troubles ensuing the implementation of a new radiographic imaging technology. Based in the theoretical tradition of ethnomethodology it examines the local endogenous practices…

Recently, faculty at Pritzker School of Medicine, The University of Chicago, have made efforts to improve the depth of radiological anatomy knowledge that students have, but no insights exist as to student and resident opinions of how clinically helpful deep anatomical understanding is. A single-institution survey of second- and fourth-year…

This work explores a new approach to demonstrate possible forearm fractures in humans as an educating means for student radiographers. The Design of abnormal bones are not normally available as phantoms; the manufacturer usually produces normal human musculoskeletal models for educational purposes. Hence fractures and abnormalities are usually…

With the projected radiography healthcare worker shortfall, improved program completion is essential in order to meet workforce needs. The purpose and the specific research question addressed in this study was "Is there an association between completing the pre-admission requirements prior to beginning core radiography courses and Radiography…

To prevent radiologists from overlooking lesions, radiology textbooks recommend "systematic viewing," a technique whereby anatomical areas are inspected in a fixed order. This would ensure complete inspection (full coverage) of the image and, in turn, improve diagnostic performance. To test this assumption, two experiments were…
