Population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). As with any biological population, the size of a human population is limited by the supply of food, the effect of diseases, and other environmental factors. Human populations are further affected by social customs governing reproduction and by the technological developments, especially in medicine and public health, that have reduced mortality and extended the life span

The culture of the classroom can either support or create barriers to student success (Piffner,
2011).

Factors that foster attention, positive behavior, and academic and social success include
establishing positive relationships with students, adopting classroom management techniques,
and creating a physical arrangement that facilitates learning.

It is often a positive relationship with one teacher that facilitates school success for a student
with ADHD (Piffner, 2011).

When teachers connect with students and appreciate their unique skills and interests, students are more likely to strive for achievement and positively respond to classroom rules and procedures.


When using a proactive approach to classroom management, teachers support all students and
create conditions that prepare them for learning (Piffner, 2011).

Some strategies for positive management include clear directions, meaningful feedback, and opportunities for collaboration with peers. Here are some others.

Opportunities to Respond
Students with ADHD often have the most trouble attending during drill-and-practice assignments because of the repetitive nature of the tasks. Peer-mediated approaches such as those enumerated in the next screens are particularly effective for students with ADHD in such cases, because they increase students’ opportunities for engagement and active learning (Piffner, 2011).

Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.

Types of Education. Education goes beyond what takes places within the four walls of the classroom. A child gets the education from his experiences outside the school as well as from those within on the basis of these factors. There are three main types of education, namely, Formal, Informal and Non-formal.
