手機成癮的重要性, 根據研究與報告的顯示，高中學生上網和玩遊戲的時
間大於120分鐘的話，有33.4%會失眠且經常有上課遲到及課堂中打瞌睡情況，並且其中38.9%在學業表現上是落後的。為了探討並了解其中相關的變素的影響機制,本研究將透過學校現場與學生的初步訪談來確立了研究問題,希望透過量化的調查了解整體的實務狀況。
本研究探討技術高中機械群的學生手機成癮的狀況與成績相對於家長和導
師管理這些條件來做相關分析，並分析成績和手機成癮之相關性，研究的樣本採用立意班級抽樣，抽取高雄市某所技術高中機械群學生，總數的有效樣本為60人，以「手機成癮量表」及「家長手機管理」、「導師手機管理」進行問卷調查。所得資料經描述性統計、獨立樣本t檢定、 單因子變異數分析、相關與多元迴歸進行分析。
研究結果發現以下幾點的結論：(1)個別檢視導師與家長管理嚴格程度對
學生成績並無顯著差異 (2)整體檢視家長與導師同時存在的模型中,家長管理對學生網路使用管理越嚴，成績則顯著更高。代表如果要探索手機成癮議題是需要考量學生更完整的生活情境 (3)在使用習慣方面，在家使用手機時間長短對成績好壞有顯著差異 (4)學生手機使用的流量方案,不管是限制或無限制都對學生成績沒有顯著差異。
針對本研究最後結果，一共有三項建議可以供教師、家長參考。家長在學
生手機流量選擇上均不影響到成績，可與小孩充分溝通,因流量是否限制對成績無顯著影響。給老師的建議，因同學可以互相分享網路,故在重要的考試期間，可以取得家長同意而集中保管另外在與學生溝通方面，透過研究數據分析呈現給學生，若未來想要考取理想大學與成績進步，手機使用時間長短與成績有正相關的。最後因老師的影響力較弱，家長與老師需好好溝通學生使用手機的管理方式，這樣才有可能有效的幫助學生成績的進步。

According to the survey, cell phone addiction is a critical issue. Students who spend more than two hours on the Internet playing games have insomnia. In turn, students are late to class, dozing off in class, and doing or performing unwell in academic performance. This study established the research questions through preliminary interviews with students and observation on teaching occasions. This study investigated the current status of cell phone addiction among technical high school students and analyzed the correlation between grades to both parents' and teachers' management. The data obtained was analyzed by descriptive statistics, independent sample t-checking, one-way variance analysis, correlation, and multiple regression.
The following conclusions were obtained from this research. (1) There was no significance in different teachers' and parents' discipline on student grades. (2) In terms of usage habits, there was a significant difference between the length of time students used cell phones at home and their grades. (3) Mobile internet plan will not influence students' grades.
