關於愛，我是個小學生。

寫得很好喔，以下是我些微的修改：
標題部分：
1. investigating 應改為 investigation 較佳。
2. 觀內文得知，本文乃探討學生使用 facebook 之 ｢現況｣，而非 ｢學習｣ facebook 之情形，故標題似應就此修改。
內文部分：
1. 前三分點首句皆無動詞。
2. 第一第二次分點首句主詞部分應為動名詞型。
3. 第五分點介係詞後應接動名詞。

但如果我是妳，我會把全篇寫成這樣：
Investigagations Of Casual Facebook Using By The Case Of HUE
Goal:
The main stem of this research is onto the casual using of general HUE students, through which the following topics are managed to be reached:
1. What is the phenomenon over the normal use of students?
2. How will Facebook using modify the attitude of academic studying?
3. Can Facebook be regarded as of learning strategies?
Sampling:

4. The info in Facebook is considered of lower credibility.
5. Facebook is less recommended by college students as a main method of academic learning info gathering, nor has Facebook become one of the popular platforms for info exchanging. 

以上示例，請斟酌參考援用。
