Sedentary Mother Leads to Fatter Offspring

In recent years, corpulence in childhood and adulthood are booming, however, there is also a situation when leaner people still exist. In fact, we are living in an environment that promotes obesity. Edward Archer, a physiologist and obesity theorist, argues that sedentary habits overtake the genes and the eating greediness as the root cause of this. He found enough evidence supporting his theory.

The first one is based on his finding that when two mice, genetically identical, ate identical food resulted in different body mass. So, food and DNA weren't the overweight factors. Then he also found that pregnant mice without wheels practice delivered the fatter descents. This is getting worse in the subsequent generations. Moreover, regarding his literature review, Edward also pointed out the metabolism differences between active pregnant mother and the inactive. The fetuses grow so fast within the inactive cases.

Second, the study of born babies by egg donation convinced that the egg donor's body mass, her own birth weight and the birth weight of her other children have no relationship with the birth weight of the baby from the donated egg.

Overall, the level of physical activities become the underlying aspect of obesity. It is suggested that having physical exercises will lead to a better metabolism within moms-to-be that surely will increase the possibility of bearing healthier children.

Computers Hardly Take Over Teacher's Role in Education

The improvement of information technology and the expanding range of computerization contribute changes in education system. It is believed that no more teacher needed in the classroom. However, I believe that teacher will still exist with three reasons while computer becomes more popular.

First of all, as Indonesia comprises wide range of islands, there are disparities amid one another. It seems difficult to consider all of the islands under one assumption in which having good information technology infrastructure. There are many remote areas where people struggle to have a better education with limited building, poor network connection also a little number of individuals who are familiar using computer. Thus, it is impractical to utilize computers as a primary tool in educating people of these areas. Teachers are still playing important role to assist them.

Second, interaction between teachers and students instills moral values which will affect their interpersonal relationship in the future. Teachers with good communication skill and ability to develop a pleasant learning environment will better attract students so that they will replicate that method in their personal life. Moreover, in an early learning, children will easily do good behavior as their teacher give them good real examples, such as how to politely shake hand, how should they greet other people with a nice way, etc. Since it involves emotion it is nearly impossible to be overtaken by computer media.

 

Lastly, teachers also have an important role as a motivator of their students related to study also a substitute of parents within educating their children. Teachers can benefit from direct interaction with their students to psychologically understand exactly what become learning problems then they can propose a suitable solutions that will motivate their student keep spirit for studying. In addition, when parents entrust children's education to an educational institution, it means that the school should take over half of parents' responsibilities. The existence of teacher make it possible help children in learning activity and take control over them.

All in all, teachers will never been replaceable due to their vital role in education both technical and emotional. For the sake of successful teaching, it seems unthinkable computers will do as good as teachers. It should be used as supporting tools for teachers in learning process as it will benefit in efficiency effectiveness.
