In the manual science teachers can find practical steps and examples of how to use the developed pedagogical tools - models, examples and experiments in their everyday educational process. The manual is based on the approach for development of comprehension in science education, in particular the development of reverse thinking and the fact that its existence is a direct sign of understanding. The manual aims to significantly ease the the job of teachers and give in their hands ready-to-use tools to support learning of students, since it is quite a difficult job to create the right models for each science concept and it may take too long to explain without them the new study subject.
The horizontal ("x") value in a pair of coordinates. How far along the point is. Always written first in an ordered pair of coordinates such as (12,5 ...
The addition of two numbers is the total amount of those values combined.
An ordinary fraction is a pair (a, b) of two natural numbers a and b, with b different by 0. The top number is the numerator and the bottom is the ...
In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angl ...
Is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane.
They are two perpendicular straight lines that intersect in a point called the origin of coordinates (0,0). The X axis is the one that runs horizon ...
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the center; equivalently it is the curve traced ...
A circumference is a curved line where all its points are at the same distance of another one, called center.
Is the number that multiplies the literal part in a monomial.
A geometric sequence is a group of numbers that is ordered with a specific pattern. The pattern is determined by a certain number that is multiplied ...
A cone is a solid object that is formed when a right triangle is rotated around one of its two short sides, the cone's axis. The hipothenuse of ...
Constant means non-varying. Constant may have two different meanings. It may refer to a fixed and well-defined number or other mathematical object. T ...
A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second num ...
A curve (also called a curved line in older texts) is, generally speaking, an object similar to a line but that need not be straight.
The degree of a polynomial is the highest power of the variable that occurs inside that polynomial.
The denomenator shows how many parts the whole was divided into.
The bottom number is the Denominator, it is the number of parts the whole is divided into.
The distance from one side of the circle, to the other, passing through the center.
A divisor of an integer n, also called a factor of n, is an integer which evenly divides n without leaving a remainder.
When the plane forms an angle 0º < a <180º with the axis, it is neither perpendicular nor parallel to the generator of the cone.
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point.
The literal part of an algebraic expression is constituted by the letters (variables) and their exponents.
A multiple of a number is another number which, divided by the number, leaves no remainder.
Multiplication is a mathematical operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, ...
The top number in a fraction is the numerator and shows how many parts were taken from the whole.
In mathematics, an operation is a calculation from zero or more input values to an output value.
The vertical ("y") value in a pair of coordinates. How far up or down the point is. Always written second in an ordered pair of coordinates such as ( ...
Two straight lines are parallel when they are in the same plane but do not intersect, which means that do not have a point in common.
Parallel lines are two lines that are always at the same distance and never touch.
A flat, two-dimensional surface that extends infinitely far.
A point is an exact position or location on a plane surface.
A plane figure with at least three straight sides and angles, and typically five or more.
Is the abbreviation of a product of the same number for itself many times. A power is composed by the base (the number that is multiplied by itself m ...
A straight line from the center to the circumference of a circle or sphere.
Without order. Not able to be predicted. Happening by chance.
A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
An outcome of a random experiment. When we sample a random variable, we obtain one specific value out of the set of its possible values. That particu ...
It is the part of a straight line that is limited by two points.
In mathematics, a set is a collection of distinct objects, considered as an object in its own right.
Two or more monomials are similar if they have the same literal part.
Is the straight line around which the curve rotates.
