本研究旨在探討COVID-19疫情期間,國小學童家長運用即時通訊軟體 LINE(LINE@)與老師進行親師溝通之現況。研究方法採用隨機抽樣,進行問卷調查法,以公立國民小學學童家長為研究對象,回收 173份問卷 ,有效問卷共計 171 份,可用率 98.8%。將問卷調查所得資料,以敘述性統計分析、獨立樣本T檢定、單因子變異數分析、單因子相依變異數分析和皮爾森(Pearson)績差相關分析等方法進行統計分析。本研究結論如下:一、 教育程度較高的國小學童家長對使用 LINE (LINE@)可以增加親師溝通的機會有較高的認同。二、 不同年段的學童家長對運用 LINE(LINE@) 於親師溝通的知覺情形之使用情形有差異,且達到顯著差異。三、 不同學校規模的學童家長對運用 LINE(LINE@) 於親師溝通在知覺有用性有差異,且達到顯著差異。 四、 COVID-19停課期間,國小學童家長每週運用 LINE (LINE@)於親師溝通之時間對知覺易用性有差異,且達到顯著差異。 五、 國小學童家長對運用 LINE(LINE@) 於親師溝通在知覺情形與使用行為意圖呈現正相關。 依據研究結論提出相關建議,研究成果可提供給欲使用即時通訊軟體LINE或相關即時通訊軟體進行親師溝通的國小學童家長和教師作為參考,並提出對未來相關研究之建議。 This study explores the current situation of Parent-Teacher communication using the instant messaging software LINE(LINE@) between parents of elementary school children and teachers during the COVID-19 pandemic.The study method uses random sampling to conduct the questionnaire survey method. The subjects of this study are parents of elementary school children.171 valid questionnaires were collected from 173 questionnaires (valid rate 98.8%).The data obtained from the questionnaires were analyzed using narrative statistics, independent sample T-test, single-factor analysis of variance, Repeated measured ANOVA and Pearson product difference correlation analysis. The conclusions of this study are as follows:1. There were no differences in the perceptions of parents of children from different backgrounds regarding the use of LINE (LINE@) in parent-teacher communication.2. The use of LINE (LINE@) in parent-teacher communication varied among parents of children in different age groups and reached significant differences.3. The perceived usefulness of using LINE (LINE@) for parent-teacher communication varied among parents of children of different school sizes and reached significant differences. 4. During the COVID-19 pandemic, there was a significant difference in the amount of time parents of elementary school children used LINE (LINE@) to communicate with their teachers on a weekly basis regarding perceptual ease of use.5. Parents of elementary school children showed a positive correlation between their perceptions of using LINE (LINE@) in Parent-Teacher communication and the behavioral intentions. Based on the research conclusions, relevant suggestions are made. The research results can be provided to the parents and teachers of elementary school children who want to use the instant messaging software LINE or related instant messaging software for Parent-Teacher communication as a reference, and put forward suggestions for future related research.
