1 Forces for development

Working in mathematics education involves a sense of both past and future, and how the two combine to influence the present. It may seem that, because the past has already happened, it cannot be altered; however, you can alter how you perceive the past, and what lessons you take from it. Each of us has a personal past in mathematics education—the particular events of our personal lives, who taught us, where, what and how they taught us, and what we took from the experiences. Each of us also

MAS.450 Holographic Imaging (MIT)
MAS.450 is a laboratory course about holography and holographic imaging. This course teaches holography from a scientific and analytical point of view, moving from interference and diffraction to imaging of single points to the display of three-dimensional images. Using a "hands-on" approach, students explore the underlying physical phenomena that make holograms work, as well as designing laboratory setups to make their own images. The course also teaches mathematical techniques that allow the b

6.4 The principle of proportionality

This principle has been developed and refined by the ECJ and is also covered by Article 5 EC:

Any action of the Community shall not go beyond what is necessary to achieve the objectives of this Treaty.

However, given that the objectives of the Community are defined very widely in Article 2 EC, the principle of proportionality is not always the easiest tool for curbing EU legislative enthusiasm.

6.3.1 Prototyping

The first prototypes may be made of any convenient material, such as clay, plaster-of-Paris or wood. Plastic models can also be made by fabrication or vacuum forming of thin sheet. Their primary function is to ensure that the product has ‘customer appeal’ when considered in aesthetic or ergonomic terms. This is particularly important for products which are to be consumer durables. It may be the first time in the design process that the concept sketches and initial engineering drawings are

Applications of Linear Equations
This video clip describes how math is applied to the real world situations through word problems. The applications of linear equations are seen throughout all our math courses after Algebra. To understand applications of linear equations we need to have an understanding of slope, how to interpret a graph, and how to write an equation. In upper-level Algebra, we apply systems of linear equations to these problems as well. (1:45)

3.1.4 (D) Cause and correlation

Pupils should be taught to distinguish between two types of relationship in science – causal, where there is a known mechanism relating an effect to a cause; and correlational, where identified variables are associated statistically but for which there is no well-established causal link.

Introduction

This unit is concerned with two main topics. In Section 1, you will learn about another kind of graphical display, the boxplot. Boxplots are particularly useful for assessing quickly the location, dispersion, and symmetry or skewness of a set of data, and for making comparisons of these features in two or more data sets. The other topic, is that of dealing with data presented in tabular form. You are, no doubt, familiar with such tables: they are common in the media and in reports and
