Recently, audio-visual feedback produced through screencast technology has received increasing attention. Yet, as opposed to synchronous (immediate) and bi-directional (a two-way process) audio-visual feedback, most recent research has focused on asynchronous (delayed) and unidirectional (a one-way process) audio-visual feedback. Therefore, this…

A novel technology that employs computer vision (CV) to carry out an automatic titration experiment is presented. The experiment is designed to facilitate understanding of the basics of the CV technology and its application in chemistry among undergraduate students. The standard chemical procedure of titration has been chosen, since it is…

This three-article dissertation explored tutors' perceptions of online writing tutoring. Article One is a literature review of writing programs, culmination with a discussion of online writing tutoring. Article Two is a qualitative case study that investigated how tutors perceive their work using both asynchronous and synchronous modes of tutoring…

Asynchronous online threaded discussions are widely recognized as a tool to enhance learning in the virtual classroom. While they can serve as a mechanism for reinforcing material and promoting a deeper understanding of course content, discussion boards often lack rich and dynamic dialogue, and instead serve as a field of obligatory discourse,…

Online communication forums allow students to collaborate and construct understandings of course material together, but little is known about students' discussion participation across online and blended (hybrid) classroom environments. This study begins to address this research gap by examining students' asynchronous discussions (number and length…

The field of education is experiencing a rapid shift as internet-enabled distance learning becomes more widespread. Often, traditional classroom teaching pedagogical techniques can be ill-suited to the online environment. While a traditional entry-level class might see a student attrition rate of 5-10%, the same teaching pedagogy in an online…
