Grading (education)

Grading in education is the process of applying standardized measurements of varying levels of achievement in a course. Another way the grade point average (GPA) can be determined is through extra curricular activities. Grades can be assigned as letters (generally A through F), as a range (for example 1 to 6), as a percentage of a total number of questions answered correctly, or as a number out of a possible total (for example out of 20 or 100).

In some countries, all grades from all current classes are averaged to create a Grade Point Average (GPA) for the marking period. The GPA is calculated by taking the number of grade points a student earned in a given period of time of middle school through high school. GPAs are also calculated for undergraduate and graduate students in most universities. The GPA can be used by potential employers or educational institutions to assess and compare applicants. A cumulative grade point average is a calculation of the average of all of a student's grades for all of his or her complete education career.

Grade (slope)

The grade (also called slope, incline, gradient, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the gradient in calculus where zero indicates gravitational level. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which run is the horizontal distance and rise is the vertical distance.

The grades or slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described. Grades are typically specified for new constructions (such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle circulation routes).

Nomenclature

There are several ways to express slope:

Jet (song)

"Jet" is a song by Paul McCartney and Wings from their album Band on the Run. Supposedly written about a puppy that McCartney owned, the song was the first British and American single to be released from the album. The song peaked at number 7 in both the British and American charts on 30 March 1974, also charting in multiple countries in Europe. It has been released on numerous compilation albums, and has since become one of the band's most well-known tracks.

Along with "Helen Wheels" and "Junior's Farm", "Jet" is another McCartney song where his primary inspiration for composing the song arose in daily life.

Background

Reviewers have reported that the subject of the song is McCartney's Labrador Retriever dog named "Jet". McCartney has also substantiated this claim.

However, in a 2010 interview on the UK television channel ITV1 for the program Wings: Band on the Run (to promote the November 2010 CD/DVD re-release of the album) McCartney explained that Jet was the name of a pony he had owned, although many of the lyrics bore little relation to the subject; indeed, the true meaning of the lyrics has defied all attempts at decryption.

Ground Control (film)

Ground Control (Jet) is a 1998 disaster thriller film directed by Richard Howard and starring Kiefer Sutherland, Bruce McGill, Kristy Swanson, and Robert Sean Leonard. The film also features a cameo by former baseball player Steve Sax in the role of an airline co-pilot.

Plot

Chicago air traffic controller Jack Harris (Kiefer Sutherland) was cleared of liability for an ill-fated flight under his authority which resulted in the loss of all 174 souls aboard. He subsequently left the job and went on to design air control software, until five years later when T.C. Bryant (Bruce McGill), his ex-colleague who had since transferred to Phoenix, pleads for help on New Year's Eve, due to a critical staff shortage and with torrential weather predicted.

Jack's return to the control room is met with both warmth and disdain, particularly when he experiences flashbacks of the crash. The atmosphere rapidly becomes much more serious as the storm approaches and, with the control tower suffering power cuts, the team is forced into manually directing busy air traffic through severe turbulence.
