Rather than a no-homework policy for second graders, Cooper said he would recommend that homework for kids at this age be kept short and simple. It should take no more than about 20 minutes a night for second graders to complete their homework, he said. That means first graders get 10 minutes of homework, second graders get 20 and so on. But too much homework in second grade or assignments that are too hard can have a negative impact on young learners, Cooper said.
Some parents who are extremely concerned about ensuring that their children achieve to their maximal ability may put pressure on educators, and this has led some teachers to assign students too much homework, especially at the high-school level, Cooper said.
But the key is for students to get the right amount of homework — not too much of it and not too little — so that it can have positive effects on learning and school performance, Cooper said.
But other educators are steadfast that the right amount of homework in elementary school may be little to none. Research suggests that homework in elementary school does not have a positive effect on student achievement, and could even have a negative impact, said Etta Kralovec, an associate professor of teacher education at the University of Arizona South, and the author of "The End of Homework" Beacon Press, Science Assignment Help will always prove to be a helping hand to you.
Science Assignment Help is a need of the hour, particularly for students of science. Science Assignment Help will help you with problems from school to college level. Science Assignment Help is a sea of clarity in the sea of madness. The word Science comes from the Latin word Scientia meaning knowledge and in the broadest sense, it is any systematic knowledge-base or prescriptive practice being capable of resulting in a prediction.
This is why science is known as highly skilled technique or practice. The basic purpose of science is to help people understand this world and their surroundings. It satisfies the natural curiosity of human beings by giving them logical answers.
