Homework

Homework, or a homework assignment, is a set of tasks assigned to students by their teachers to be completed outside the class. Common homework assignments may include a quantity or period of reading to be performed, writing or typing to be completed, problems to be solved, a school project to be built (such as a diorama or display), or other skills to be practiced.

Main objectives and reasons for homework

The basic objectives of assigning homework to students are the same as schooling in general: to increase the knowledge and improve the abilities and skills of the students. However, opponents of homework cite homework as rote, or grind work, designed to take up children's time, without offering tangible benefit. Homework may be designed to reinforce what students have already learned, prepare them for upcoming (or complex or difficult) lessons, extend what they know by having them apply it to new situations, or to integrate their abilities by applying many different skills to a single task. Homework also provides an opportunity for parents to participate in their children's education.

General officer

A general officer is an officer of high rank in the army, and in some nations' air forces or marines.

The term "general" is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of captain general, which rank was taken from Middle French capitaine général. The adjective general had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction.

Today, the title of "General" is known in some countries as a four-star rank. However different countries use different systems of stars for senior ranks. It has a NATO code of OF-9 and is the highest rank currently in use in a number of armies.

General officer ranks

The various grades of general officer are at the top of the military rank structure. Lower-ranking officers in land-centric military forces are typically known as field officers or field-grade officers, and below them are company-grade officers.
