Workshop 7: Children's Ways of Knowing
With Dr. Herbert Ginsburg. Children know a good deal of informal mathematics before they enter school. Clinical interviews help teachers understand what children know. In this session, you will see young children’s natural mathematical inclinations and watch as they construct their ideas. Observe Professor Ginsburg helping teachers of young children rethink t

Acceleration Lab Experiment
In this slow motion video for IPS Schools by Clayborn a ball is released on an inclined plane and accelerates due to the force of gravity. At the bottom of the first inclined plane to the beginning of the second inclined plane the ball stops its positive acceleration by nearly maintaining its horizontal speed. On the second ramp the ball accelerates backwards down the slope, or loses speed to a point where it momentarily comes to rest. Therefore this video demonstrates POSITIVE ACCELERATION, ZER

4.7: Quartiles and the interquartile range

The first alternative measure of dispersion we shall discuss is the interquartile range: this is the difference between summary measures known as the lower and upper quartiles. The quartiles are simple in concept: if the median is regarded as the middle data point, so that it splits the data in half, the quartiles similarly split the data into quarters. This is, of course, an over-simplification. With an even number of data points, the median is defined to be the average of the middle two: de

Finding the Hypotenuse
The hypotenuse of a right triangle is the side that is opposite of its right angle. Sometimes we have problems that ask us to find the missing hypotenuse of a right triangle. This video describes how to use the Pythagorean theorem to find the hypotenuse, but only when the length measure of the two legs is known. (1:16)

4.3.2 Removal of CO

Under fuel-lean conditions (excess O2), the oxidation of CO has been studied over a very large range of single crystals and model noble metal catalysts, one of the most intensively investigated examples being the Pd(111) surface. Although this metal is not a component of the current three-way catalyst used in the UK, it is worth considering the results in some detail for a number of reasons. The reaction on metals such as Pt is in many ways similar to that on Pd and, in any

9.3 Linear notes

This is the most common form of note-taking. It involves writing in sequence the points you want to note. As with all note-taking, the aim is to pick out and record the most important points. Avoid simply writing out most or all of the text again.

Try to write your notes in your own words as this will help you understand what you have been reading about. Also add a reference to which page(s) of the text your notes refer so you can easily find your way back to the relevant part of the te

2.2.1 Normal galaxies

Normal galaxies are made up of stars and (in the case of spiral and irregular galaxies) gas and dust. Their spectra consist of the sum of the spectra of these components.

The optical spectra of normal stars are continuous spectra overlaid by absorption lines (Figure 1). There are two factors to consider

3.2 Necessities and luxuries

As the division of opinion between the government and low income people illustrates, definitions of poverty are the stuff of political debate. People in the Rowntree studies tended to focus on ‘paying bills and food’. Most people's list of basic needs would also include adequate food and clean water, clothing, shelter and heating. But are there also less apparently physiological, more evidently social, necessities of life?

2 2 Note taking from an audio visual text

The first important point to make is that note taking is more than a process of summarising everything that you see; it must be an active process of engaging with the material and thinking it through for yourself. In the videos, the multidimensional nature of the visual images and the stories they convey means that you will not be able to take in everything on first viewing. The videos allow us to present visual as well as audio information and in a form that makes it easier for you to revisi

2.3 Other influences on market demand

What about other variables which may affect demand? Let us consider four such variables. As is often the case in economics, the first two points involve understanding some rather formal relationships between variables, in this case price and income.

  1. The price of other goods. Two goods x and y are known as substitutes if the quantity demanded of good x increases after a rise in the price of good y. The

The Science Behind Self-Control
Have you ever wondered why you can't bring yourself to choose the foods that are healthy over the ones you know are unhealthy? Researchers are not only trying to find out why, but what parts of the brain govern behaviors of self-control and how we can work to improve them. Ben Hayden is a neuroscientist and Assistant Professor of Brain and Cognitive Sciences at the University of Rochester. He offers his insights based upon his research and how it has the potential to apply not only to our choice

1.4 Conclusion

In this course, you have learned about boxplots and about ways of dealing with data given in tabular form.

A boxplot is a way of presenting certain summary statistics and other characteristics of a data set in graphical form. It gives a quick graphical impression of the location, dispersion and the general pattern of skewness in data set, as well as drawing attention to unusually large or small values. In comparing two or more data sets, it is often useful to draw comparative boxplots (
