本研究關注高中生的是否具備全球公民意識，以及為其未來的學習做對接，進而探討與全球公民意識關聯的學校因素，以提出提升高中生全球公民意識的具體方式。本研究以2018年臺灣參與國際學生能力評估計畫（Programme for International Student Assessment, PISA）之4,899名高中生學生資料探討學生於學校全球公民素養教育、學校媒體與資訊素養教育與學生全球公民意識之關聯性，以逐步多元回歸進行分析。研究結果發現臺灣高中生普遍具備全球公民意識，學校全球公民素養教育、學校媒體與資訊素養教育與全球公民意識有顯著而正向的關聯，也就是說學生於學校接受的全球公民素養教育較充足、在學校接觸的媒體與資訊素養教育更完善，學生則具有全球公民意識。並針對結果，提出具體建議。

This study examines whether senior high school students have the global citizenship awareness to prepare for their future learning. The goal is to propose specific methods to enhance high school students' global citizenship awareness. The study also explores school factors associated with their global citizenship awareness. The data for this study includes 4,899 senior high school students in Taiwan who participated in the International Student Assessment (PISA) 2018. The purpose is to explore the relationship between students' global citizenship education at school, media and information literacy education at school, and their global citizenship awareness. The analysis was conducted using stepwise multiple regression. The conclusions found out a significant and positive relationship between students' global citizenship education in school, media and information literacy education at school, and their global citizenship awareness among senior high school students in Taiwan. In other words, students who receive more comprehensive global citizenship education at school and media and information literacy education at school tend to have a higher level of global citizenship awareness. Based on the conclusions and discussion of this study, some specific suggestions are provided.
