3.2 Organisational memory systems Without a memory, humans are paralysed in the present moment, unable to reflect on lessons learned or to anticipate the future. You will notice that the heading given to the framework in Figure 3 is corporate memory. The whole dynamic system of people and technologies is conceived as constituting an organisation-wide resource that will enable it to become a more intelligent, learning organism, to pursue the anthropomorphic metaphor. The organisational memory challenge goes beyond tradi
2.4.1 From Heidegger to knowledge technologies Because each transformation from one ‘knowledge state’ to another (Figure 2) is an act of interpretation, there is no such thing as objective knowledge representation, or indeed objective classification or codification of any sort (in software or any other medium): there is always a viewpoint. This leads to the view that information and communication systems cannot be thought of as neutral; in their formal structures and operations they embody the goals and perspectives of their deve
2.3.1 From tacit pre-understanding to symbolic representation This section reflects many of the critiques that have been made of efforts to apply technology to knowledge work without taking seriously the differences between human and artificial knowledge representations. Stahl (1993a,b) has presented an informative analysis of the transformation of knowledge from tacit to explicit to formally codified representations in computer-interpretable form, emphasising the centrality of interpretation situated in the workplace (Figure 2). Stahl also seeks
3.3 Limited positive characterization The painted portrait was, however, perceived to be more than a mere ‘map of the face’. It was also meant to reveal aspects of the inner as well as the outer being. Classroom Triangles Form vs. Function Sneaking Up On Sneakers Snakes Go to Great Lengths to Fool Predators-Find Out How! Every Picture Tells a Story: K-4 Introduction People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance. Communication networks have become very important, and modern society depends on them for the smooth operation of economic and social activities.

Alternatively you may have been recruited to the role for that very purpose. Perhaps you lie somewhere in the middle, having joined the body of teaching assistants just as the role was being reviewed and bearing witness to its expansion and development. In the final section of this unit, we focus with a degree of detail on the practice of teaching assistant Caroline High 3.4 Evolving roles in teaching The impact of the expanding contribution of teaching assistants on the teacher's role is generally recognised as being positive. It is worth acknowledging, however, that many teachers have had to make adjustments to their practice in order to work with teaching assistants as team colleagues. Despite the presence of assistants in primary schools, the focus of much initial teacher training is on teachers working in classrooms on their own rather than as collaborators with other adults. While th 3.1 What is the value of teaching assistants? Hilary Cremin et al. (2003) in their evaluation of the ways in which teachers and teaching assistants can work together in teams, suggest that, while there is enthusiasm for additional support, little attention is given to how this actually works in classrooms. It is true that learning support staff have been introduced into classrooms without clear research evidence that they can make a difference to children's learning, but then life often moves faster than the supply of research evidence.< 2.2 Profile of teaching assistants: an overview Traditionally the primary education sector has employed a high proportion of women teachers. In England and Wales in 1980, male teachers constituted around 23 per cent and female teachers 77 per cent of the workforce (DES, 1980). By 1999 the number of men had decreased to 17 per cent and that of women had increased to 83 per cent (DfES, 2002). There is reason to think that this trend is continuing. Primary teaching is certainly a ‘feminised’ workforce, but there are also anomalies re 1.6 Teaching assistants in Europe Teaching assistants and other related learning support staff are also to be found in the schools for children of British armed forces posted overseas, in the schools of other European countries and, indeed, further afield in countries such as the USA, Canada and Australia. A survey conducted by the National Union of Teachers (NUT, 1998) highlighted some interesting support roles found in European schools, and it is worthwhile to consider these in the light of the developing role of teaching a 1.5 Growth of the teaching assistant workforce In all four UK countries there has been a growth in the number of teaching assistants working alongside teachers in primary classrooms. As we have indicated, the seeds of this development were sown some thirty years ago when support staff were employed to support the inclusion of children with special educational needs in mainstream classrooms. Teaching assistants (then and now called ‘special needs assistants’ and ‘learning support assistants’) were recruited to provide ind 1.3 Shift in core duties Over the last ten years, many teaching assistants across the UK have experienced a notable change in their day-to-day involvement in schools. A student on The Open University's specialist teacher assistant (STA) course, who started working in schools in 1975, described the shift in her role as ‘from pencil sharpener to work planner’. Another student who had extensive experience of working with children with special educational needs talked of moving ‘from just caring, to learn 1.2 Titles, terminology and core duties As we have said, in the UK there are a number of terms in current use to describe those who provide learning support to children. It would be wrong to suggest that these terms describe the same roles and responsibilities. Rather, they relate to important role distinctions and are significant because they reflect the wide variety of work that learning support staff do. To get a sense of this variety, we made telephone contact with eight schools across the UK to ask what titles they assi
In this activity, students will use bearing measurements to triangulate and determine objects' locations. Working in teams of two or three, students must put on their investigative hats as they take bearing measurements to specified landmarks in their classroom (or other rooms in the school) from a "mystery location." With the extension activity, students are challenged with creating their own map of the classroom or other school location and comparing it with their classmates' efforts.
Students model and design the sound environment for a room. They analyze the sound performance of different materials that symbolize wallpaper, thick curtains, and sound-absorbing panels. Referring to the results of this analysis, they then design another room based on certain specifications and test their design.

The goal is for students to understand the basics of engineering associated with the design of different types of athletic shoes. Sneakers are one of the most commonly worn shoes in our American culture. They provide comfortable support for our feet as we go about our active lives as students, athletes, educators, and engine

These activities are designed to create a sense of disequilibrium in the visual perception of students to make them aware of different ways to to view a picture. The students will view the images, decide what they see in each, record their ideas, and write a story based upon these findings.
