The purpose of this study is to find out teachers view on manipulatives as a way to concretize a certain mathematical content and to highlight knowledge and experiences within the range of using manipulatives to concretize. By answering the questions below different approaches a teacher may have towards the manipulatives and how that may impact on student?s learning will also be discussed in comparison to mainly traditional and socially constructive theories of learning.What is the teachers view on manipulatives as a way to concretize?What purpose do they have when using manipulatives?According to the teachers, what does it mean to concretize a certain mathematical content?According to the teachers, what connection is there between manipulatives and concretizing?Through interviews and observations conclusions can be made that the teachers are in general positive towards using manipulatives as a way to concretize a certain mathematical content although the definition of what a manipulative is differ somewhat between the teachers. The teachers working with manipulatives do it in a well thought out fashion but more research is needed to furthermore define the purpose of using manipulatives. Few countries spend so much time concretizing and working with manipulatives as Sweden do, but still Sweden score below the OECD-average on the mathematical PISA-tests.

The capability to know what knowledge there is and where it resides within an organization is becoming increasingly important in the new knowledge-based economy. This paper takes on a practise-based view of knowledge in order to decide on a course of action for how to successfully implement knowledge management within a knowledge-based company. By considering all knowledge as more or less contextual and socially constructed, knowledge is divided into three dimensions depending on the degree to which it is tacit, namely: information, knowledge and skills. The paper then discusses inhibitors and enablers for transferring knowledge via these three dimensions respectively. The empirical findings are based upon a case study of Faveo. It is shown that Faveo, like most organizations, has til now focused on the collection of codified knowledge, i.e.

This study is based on a proposition about the legislation regarding sexual offences prepared by a commission initiated by the Swedish government in 1972 which was presented in 1976. The purpose of this study has been to ascertain the commissions views on rape based on their representation of the problem, their presuppositions and assumptions regarding it and future consequences in behavior for victims and offenders of the crime. The key results of this study is that the commission regarded the ?problem? of the then current legislation to be non-consistently with the time being. In their opinion the legislation needed to be loosened from its moral strings and be adjusted to the ?new? sexually liberal era.

The purpose of this study is to highlight play and learning in the lower school ages in organized and non-organized break actives. The premise is that the break is a part of the schoolday and that the school has responsibility to live up to the goals and guidelines of the curriculum even in recess. Leisuretime-pedagogy and the professional competence the pedagogs possess about games and the social relations of children are also in focus in this study. The study is a qualitative study where the empirical material consists of observations in a schoolyard environment during one week and interviews with children. The material has then been interpreted and analyzed using Lev S.

In recent time, agile methods have been devoted much attention, and the concept is widely used in the IT industry in particular. An increasing number of companies are interested in this way of working. The following report is the result of a study on the ability to create value for customers in business development through the use of agile methods. We ask what the advantages and limitations of agile methods are in the creation of customer value. Grounded Theory and an initial literature review was used to answer this question.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

The aim of this thesis is to describe the thoughts and attitudes that parents have regarding reading aloud. In today?s society the positive effects of reading aloud are often pointed at and in the perspective of the new learning theories I found the issue even more interesting.The two main questions posed are: How do the parents describe the practice of reading aloud?Is the parents? life situation and background visible in their descriptions and in that case how does it show in their thoughts about reading aloud?The theoretical perspective of the thesis is sociocultural and can be divided into two themes. The first theme concerns the learning process that can be the result of reading aloud and the second theme focuses on social aspects. The results of the study show that parents think that reading aloud is valuable and positive.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

This essay discusses the subjective observations and opinions on the Swedish concept of stegintegrering, a form of mixed grade education in the subject modern languages at upper secondary level. I interviewed two headmasters, four teachers and conducted an online survey with 39 pupils in order to find out what effects the concept of stegintegrering has on teaching and learning from a teacher and pupil perspective. Due to the extent of this essay no general conclusions can be made but certain connections could be found. For once there was a connection between group size and the possibility of teaching each group separately during one lesson per week and the attitude of the concerned teachers and pupils towards stegintegrering. While both headmasters and teachers claimed that the cooperation between pupils across all levels was the main purpose of stegintegrering as it helps their learning and understanding, my study showed that many pupils did not really want to cooperate and that teachers often find it hard to construct tasks that stimulate every group.

We have made a suggestion for a map based search tool used with a database containinginformation on natural disasters. The database is being developed by NCO (SwedishCentre for Lessons Learned from Incidents & Accidents).We examined both Swedish and international examples of databases on naturaldisasters. The examples that we found were often hard to get the hang of, due to poorcompilation. The problem, that is typical of the international examples, is that the processof data collection is not standardized, as it is performed by different organizations andcompanies with diverse demands on and needs for the database. Therefore, to keep itsymmetrical, there ought to be only one department with the overall responsibility for anational database on natural disasters in Sweden.The natural disaster we based our study on was the flooding in Arvika in the year 2000.We inspected the availability of data about the flooding, and found it to be satisfying.Through contact with the municipality of Arvika, by mail and telephone, and a visit at theArvika municipality office, we acquired reports on the flooding and the joint rescueoperation that followed, and also GIS layers showing the extension of the flooding..

Healthcare in Sweden are in need of a drastic change to meet the requirements of highly developed societies, and information technology is seen as an essential part to get there. However, the Swedish healthcare have to challenge their traditional innovation approaches as well. For example, it has become more common to engage patients in the innovation process through web-based platforms. We have been focusing on an approach called co-creation by studying a workshop, in which potential users and other stakeholders are cooperating creatively to come up with innovative solutions in order to improve healthcare practice. Our findings suggests that co-creation may increase the mutual understanding between different stakeholders, for example healthcare professionals and IT developers, enable horizontal learning through and outside the organization and also to raise concepts and actions that are responding to healthcare needs.
