Holding Them Back: Is Repeating a Grade Ever the Right Thing? PDF Print E-mail
Business - Economics

In recent years, it seems as though more and more young students are being retained, or held back a grade, in their school. For parents who must decide whether to retain a slow learning child or send them into the next grade level, the contributing factors can be wide, varied, and difficult to sort through.

Holding a child back a grade is a choice that’s most often based on one or more of three factors: Standardized test scores, poor social skills, or serious struggles with learning “the basics.”

 When these issues begin to make parents, educators, and school officials begin to consider retention, difficult decisions must be made. The choice to hold a child back a grade should not be taken lightly, as it’s a decision that will undoubtedly go on to impact the child’s education either way. When contemplating retention for your child, it’s important to remember to treat the decision carefully, and to know that some “indicators” might not be telling you to hold your child back at all, but rather to try new methods of instruction.

Triple point

In thermodynamics, the triple point of a substance is the temperature and pressure at which three phases (for example, gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. For example, the triple point of mercury occurs at a temperature of -38.8344 °C and a pressure of 0.2 mPa.

In addition to the triple point between solid, liquid, and gas, there can be triple points involving more than one solid phase, for substances with multiple polymorphs. Helium-4 is a special case that presents a triple point involving two different fluid phases (see lambda point). In general, for a system with p possible phases, there are

triple points.

The triple point of water is used to define the kelvin, the SI base unit of thermodynamic temperature.[2] The number given for the temperature of the triple point of water is an exact definition rather than a measured quantity. The triple points of several substances are used to define points in the ITS-90 international temperature scale, ranging from the triple point of hydrogen (13.8033 K) to the triple point of water (273.16 K).

Science

Amino Acids

Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life.

When proteins are digested or broken down, amino acids are left. The human body needs a number of amino acids to:
 
Break down food
Grow
Repair body tissue
Perform many other body functions
 
Amino acids are classified into three groups:
  1. Essential amino acids
  2. Nonessential amino acids
  3. Conditional amino acids
