Background Efforts are made to enhance in-class learner engagement because it stimulates and enhances learning. However, it is not easy to quantify learner engagement. This study aimed to develop and validate an observation tool for instructor and student behaviors to determine and compare in-class learner engagement levels in four different class types delivered by the same instructor. Methods...

Background: Physical self-concept and physical self-esteem are important sources of general selfesteem and overall health. Evidence indicates that exercise leads to an enhancement in physical self-concept and physical self-esteem. Until now however, it remained unclear whether the beneficial effects of exercise were impacted by different types of exercise environments. Thus, the purpose of this...

Today we will talk about some applications of decoupling. The first application is Strichartz inequality on tori. Let T d = R/Z. For a lattice Λ ⊂ R, let TΛ = R/Λ. For instance, we may take the rectangle [0, λ1]× ...× [0, λd] and identify opposite edges. Our goal is to study the initial value problem for Schrodinger’s equation. That is, let u(x, t) : R×R→ C (or T ×R→ C or TΛ×R→ C), where x ∈ R,...

Introduction Many commentators have argued that distance education requires a qualitatively new pedagogy built on a unique relationship between the instructor and the learners. Traditional education or one-way televised learning at a distance often produces boredom. Students learn passively because the instructor is the sage and the source of knowledge (Markel. 1999). Besides, adult learners al...

At its simplest a course management system is a tool that allows an instructor to post information on the web without that instructor having to know or understand HTML or other computer languages. A more complete definition of a CMS is that it provides an instructor with a set of tools and a framework that allows the relatively easy creation of online course content and the subsequently teachin...
