A college professor wrote an article aboyt how she thinks American student are lazy. Different people have different oppinions on this subject. Although many believe that american students are lazy and others believe they are not. I think it just depends on your background, and family life. You cant just judge someone by what they dowithout knowing where they come from. Students from different countries have great work ethics, they pay attention well in class, and do really good on their work. most of their effprt comes from relations with family.
For foreign students they come to ameica to study because the education is better so their parents bring them here. Foreign students work really hard , because they came here to study and they think that its a great opportunity. But i have also met some foreign exchange students that are lazy and have really bad work ethics, and i have talked to them and they are having problems at home. Most people tink that american students are lazy, but i have met some really out going Americans. My friend Sarah Doud, she is American and she is a 3. student andshe is a hard working student. I know i kid, his name is lewis. He is a 4. 0 student and is taking way advanced classes and he is american. Those two examples i just gave are American and hard working. And they come from loving families and have loving friends. I have also met some lazy americans as well, but they come from bad families that dont care about their childs grades. There are also the middle students who are American and dont do bad, but dont do good. These students come from families who dont really care about their grades.
And its mostly students whos parents travelor are rarely home because of their work. But the students know better than to let their grades slip. These students are self motivated but i dont think that is enough. I think that they need more motivation. There are many lazy students, and there are also many hard working students. I think it just depends on the students family problems if any. Sure habits are hard to break, but there is a reason in the first place why they have those habbits. American teenages need more motivation, because i dont think they get enough.
