for me the ideal student is curious, caring, aspiring to something new. It's alive, with their difficulties, problems, not always with perfect behavior, but it is interesting to all just want to get everything out. And since we are talking about the ideal, he bred, versatile, has developed expertise in different fields can control their time, tasks and execute them, not afraid of difficulties, is respectful to elders and their peers.
Для меня идеальный ученик  - это любознательный, неравнодушный, стремящийся к чему-то новому ребенок. Он живой, со своими трудностями, проблемами, не всегда с идеальным поведением, но ему все интересно, до всего хочется добраться, все узнать. И если уж мы говорим об идеале, то он воспитан, разносторонне развит, обладает знаниями в различных областях, умеет контролировать свое время, ставит перед собой задачи и выполняет их, не боится трудностей, относится уважительно к старшим и своим сверстникам.

There are no ideal pupils, however teachers believe they exist. And their opinions differ from pupils' opinion. Teachers are sure that ideal schoolchildren are never late. Besides, they are always ready for the classes and can give arguments to any question. Grown-ups think that such children listen carefully and don't forget to make notes. They give full and correct answers. But to tell the truth, young people don't always share their image of an ideal child. As for me, those are good schoolchildren who can give a helping hand when you are in a mess, who can raise a hand when the others are not ready and answer the teacher's question. But it is true that one can't always rely on other pupils, so everybody should have to be ideal from time to time.
