Abstract: The purpose of this brief paper is to present an Online Learning Readiness Self-Check (OLRSC) system website and student teachers’ use of the system. The website allows student teachers to evaluate their online learning readiness levels and to identify their strengths and weaknesses of online learning. It also provides explanations of students’ OLRSC scores by presenting an interactive polar chart and individualized feedback with online learning tips. In addition, the system supports students to download a score breakdown picture and an online learning tips booklet to their own devices. A total of 149 student teachers used the OLRSC system website. A confirmatory factor analysis (CFA) was conducted to examine the validity of the OLRSC questionnaire for this group of students. Then students’ average scores and their use of the website are reported.
