काक चेष्टा बक: ध्यानं, स्वान् निन्द्रा तथैव च ।अल्पाहार: ब्रह्मचार्यम्, विधार्थी पंचलक्षणम् ॥

So what does the shloka says? What are the qualities which an ideal student should possess. The two lines above has lot to say. Which I have tried to list down as follows:
1) perseverance of a crow,
2) concentration of a swan,
3) light sleeper like a dog,
4) light eater,
5) staying away from home (means noise,emotions).
Kakcheshta means-similar to a thirsty crow who keeps struggling for water to satisfy its thirst, a student must work tirelessly to earn knowledge.
Bakdhaynam means-similar to a heron bird which meditates on its prey like a statue, a student must remain focused to earn knowledge
Swannidra means– similar to a dog which sleeps very less and remains alert, a student must not become lazy and remain attentive all the time.
Swalpahaari means– since food could be both nourishment as well as addiction a student must avoid eating too much.
Striyastyagi means-a student must practice self-restraince and observe celibacy.
In India, old system of education followed Gurukul system, where above qualities where stressed on.More detail about Gurukul education in India can be found here
