This study aims to explore the validity of measuring joint attention through gaze coordination in computer-supported collaborative learning (CSCL) research. Gaze coordination, aligning visual attention in social contexts, aids comprehension and communication. Many CSCL researchers use gaze coordination to gauge joint attention quantitatively.…

Interaction has received attention in different fields of applied linguistics. In the field of Second Language Acquisition (SLA), scholars have perceived interaction as a platform where L2 learners can engage in language experimentation. It has been considered in light of Long's (1981) Interaction Hypothesis, which posits that negotiation of…

Online courses must focus on the quality of interaction. As an…

This dissertation examines the patterns and types of mistakes students make on a large-scale mathematics assessment, and puts these patterns into perspective based on the textbook used and the specific content covered in a student's classroom. In order to investigate the nature of these patterns, I employ a method of analysis originally designed…
