Couch Potato or Inertia Victim?
Students design a simple behavioral survey, and learn basic protocol for primary research, survey design and report writing. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world concepts of rhythm, balance, spin, gravity, levity, inertia, momentum, friction, stress and tension.

5.2 The social construction of reality What do we mean when we say reality is socially constructed? We inhabit a social world. Many of the ‘facts’ of our lives which we take for granted are ‘facts’ only in so far as we hold common mental models about them: for example, common understandings of money, contracts, marriage, the rules of the road, democracy, to name just a few. To understand the nature of social influences on decision making we need to start from this idea that the environment within which we exist a
5.1 Introduction As we noted earlier, both the rational-economic and psychological perspectives on decision making tend to ignore the social context in which we live and work. We turn now to consider this social context. Original Copyright © 2005 The Open University.

4.6 Post-decision evaluation For most normally functioning people, maintaining self-esteem is an important internal goal. This can cause us to filter out or discount information that might show us in an unfavourable light. This is what lies behind the fundamental attribution bias. This is the tendency to attribute good outcomes to our own actions and bad outcomes to factors outside our control. While such defences against loss of self-esteem can be helpful to the extent that they help us persist in the face of adv
4.5.2 Anchoring adjustment Many decisions need revisiting and updating as new information comes available. However, most of us make insufficient anchoring adjustment: this is the tendency to fail to update one's targets as the environment changes (Rutledge, 1993). Once a manager has made an initial decision or judgement then this provides a mental anchor which acts as a source of resistance to reaching a significantly different conclusion as new information becomes available. It is what happens when one has made
4.5.1 Filtering Which of these senses do you usually tune out? From birth we start learning to filter information out and to prioritise, label and classify the phenomena we observe. This is a vital process. Without it we literally could not function in our day-to-day lives. In our work lives, if we did not filter information and discard options we would suffer from analysis paralysis: the inability to make any decision in the face of the complexity and the ambiguity of the real world. However, t
4.5 Deciding: problems of judgement We are constantly bombarded by information. Simply walking though a room risks flooding us with more sensory information that we can possibly process. Stop for a moment and consider all the different things you can see, hear, smell, or feel. Original Copyright © 2005 The Open University.

(1993) tested the effectiveness of the Wilson Reading System for improving spelling in higher education students with dyslexia. They compared this technique to a non-phonic approach that teaches visual memory techniques to help students to remember frequently misspelled words. A control group of students with dyslexia but who had specifically requested no intervention formed the control group. Both intervention groups were tutored in the given technique for two, one-hour sessions 2.4.2 Differences in sensory, perceptual and motor function As we saw in our discussion of cognitive explanations, there has been longstanding debate over the possible contribution of perceptual problems to dyslexia. Subjectively, many children and adults with dyslexic difficulties do report ‘visual symptoms’ when trying to read. These include letters and words appearing to move or ‘blur’ on the page, particular difficulties with small, crowded print, and complaints of ‘glare’ or other kinds of visual discomfort (see Figure Public Domain Music in Connexions Music Activities

An interactive applet and associated web page showing how the AAA similarity test works. Two similar triangles are shown that can be resized by dragging. The other triangle adjusts to remain similar and the angle-angle-angle elements are highlighted to show how they are involved in this test of similarity. (all three interior angles congruent).

An interactive applet and associated web page that demonstrate the concept of similar polygons. Applets show that polygons are similar if the are the same shape and possibly rotated, or reflected. In each case the user can drag one polygons and see how another polygons changes to remain similar to it. The web page describes all this and has links to other related pages.

An interactive applet and associated web page that demonstrate the volume of a cube. A cube is shown where the edge length be changed by dragging. The volume is continuously recalculated as you drag, and a unit cube grid is superimposed on the cube to illustrate the volume graphically. The calculations can be turned off for class discussion. The web page has the formula for the volume calculation, and a discussion about the subtle distinction between the volume of a cube and the volume inside th
An interactive applet that allows the user to graphically explore the properties of a linear functions. Specifically, it is designed to foster an intuitive understanding of the effects of changing the two coefficients in the function y=ax+b. The applet shows a large graph of a quadratic (ax + b) and has two slider controls, one each for the coefficients a and b. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. Applet can be enlarged to ful
