The 21st century student learns and communicates in the virtual world. In order to meet the individual instructional needs of the students, virtual science laboratories should be researched to accomplish the goal. This study evaluated the effectiveness of a virtual chemistry laboratory in enhancing students' conceptual understanding as a…

Sport philosophy is in crisis. This subdiscipline of kinesiology garners little to no respect and few tenure track lines in kinesiology departments. Why is this the case? Why isn't philosophy held in greater esteem? Is it possible that philosopher Alasdair MacIntyre's (2009) diagnosis found in "God, Philosophy, Universities" could…

The field of kinesiology has seen growth in terms of the number of highly specialized subdisciplines, such as exercise physiology, motor learning, biomechanics, sport and exercise psychology, and fitness management. While some undergraduate students may be comfortable with a chosen concentration, others may enter the kinesiology curriculum lacking…

Purpose: The aim of this study was to ascertain the effect of Problem Based Learning (PBL) on student oral communication competency gains. Methods: Eighty students from two consecutive undergraduate Kinesiology courses (Spring semesters, 2014-15) formed into 29 small groups and were studied. Oral communication competency was assessed using a…

A simple experiment on the determination of the coefficient of restitution of different materials is taken as the basis of an extendable work that can be done by students in an autonomous way. On the whole, the work described in this paper would involve concepts of kinematics, materials science, air drag and buoyancy, and would help students to…

The disadvantages of the usual linear least-squares analysis of first- and second-order kinetic data are described, and nonlinear least-squares fitting is recommended as an alternative.

A way to promote student interest and engagement in physics is by capitalizing on students' skills in arts and crafts to design and make physics-based toys. This article illustrates how two students (averaging 14 years of age) in the authors' science class designed and fabricated a variation of a physics-based teaching aid that demonstrates the…

Quantum dots (QDs) are useful for demonstrating the particle-in-a-box (PIB) model utilized in quantum chemistry, and can readily be applied to a discussion of both thermodynamics and kinetics in an undergraduate laboratory setting. Modifications of existing synthetic procedures were used to create QDs of different sizes and compositions (CdS…

In this article, we examined Past Kinesiology Doctoral Students' (DS) perspectives on issues related to their career experiences. Using the Kinesiology Doctoral Student (KDS) survey, 56 past DS provided information on nine different aspects related to their current careers. Specifically, the items consisted of (a) type of position, (b) employment…

In this thematic issue, we examined Doctoral Students' (DS) perspectives on six topics: (a) dissertation, (b) teacher training, (c) research training, (d) advisors, (e) doctoral program and department, and (f) career perspectives (past DS). Each topic was viewed through three lenses: (a) status (past and current DS), (b) gender, and (c)…

The classroom jumping ring demonstration is nearly always performed using alternating current (AC), in which the ring jumps or flies off the extended iron core when the switch is closed. The ring jumps higher when cooled with liquid nitrogen (LN2). We have performed experiments using DC to power the solenoid and find similarities and significant…

FlashPhotol is an educational software package that introduces students to the kinetics of transient species and fast reactions. This is achieved by means of a computer-simulated flash photolysis apparatus that comprises all major functional elements and that students can use to perform various experiments. The experimental interface presents a…

An inexpensive enzyme kinetics laboratory exercise for undergraduate biochemistry students is described utilizing tyrosinase from white button mushrooms. The exercise can be completed in one or two three-hour lab sessions. The optimal amounts of enzyme, substrate (catechol), and inhibitor (kojic acid) are first determined, and then kinetic data is…

General chemistry courses are often the foundation for the study of other science disciplines and upper-level chemistry concepts. Students who take introductory chemistry courses are more often from health and science-related fields than chemistry. As such, the content taught and assessed in general chemistry courses is envisioned as building…

In high-school teaching of mechanics, we deal, among other things, with the nature of static and kinetic friction, forces that are proportional to the normal force. Under the influence of frictional forces, a body moves down a rough sloped decline at a fixed rate of acceleration that is independent of its mass. This situation does not apply to…
