Wireless Internet technology is gaining a foothold on more and more campuses, yet few studies have investigated how wireless Internet supports and enhances a student-centered learning environment. This study seeks to fill the gap by developing an instrument to measure how wireless Internet supports student-centered learning. A web survey was designed and administered at a public university in the USA where participants were student wireless Internet users. Structural equation modeling employing Partial Least-Squares approach was used to test the research model. The model explains 77% of the variance (R [squared]) in student-centered learning environment. The survey results suggest that wireless Internet has a positive and significant influence on student-centered learning in three dimensions: pedagogical, technological, and cultural learning.
