Elevers samtalsaktiviteter och matematiska lärande då datorer används som läromedel : En litteraturstudie om elevers samtalsaktiviteter och matematiskas lärande då de använder bärbara datorer och handdatorer som läromedel

Under de senaste åren har det skett en integrering av informations- och kommunikationsteknik (IKT), exempelvis datorer, i såväl samhället som i skolans undervisning. Syftet med den aktuella litteraturstudien är att undersöka vilka samtalsaktiviteter som eleverna deltar i då de använder bärbara datorer eller handdatorer under matematiklektionerna, samt att belysa vilka möjligheter och hinder som framträder. Som teoretisk utgångspunkt ligger ett sociokulturellt perspektiv på lärandet där språket, den miljö som eleven befinner sig i och de redskap som används beskrivs som betydelsefulla aspekter för lärandet. I läroplanen förtydligas att elever ska ges möjlighet att delta i kommunikativa samspel och att modern teknologi ska användas så att eleven kan inhämta, lära och utveckla sin förmåga att kommunicera matematik. Tidigare forskning kring matematik visar att elevers kollaborativa lärande och användande av IKT främjar elevernas matematiska kunskaper och delaktighet i samtalet.

Vardagsmat eller domedag? Marknadsföring av ekologiska varor genom svaga och starka rädslor

In a time when concern for the environment is a topic that is met with both love and hatred, organic goods and services become increasingly common on the market. Communication efforts with the purpose of increasing the proportion of organic products consumed are being conducted by both private and public actors. However, achieving attitudinal and behavioral change within complex areas such as this comes with many difficulties.Within public opinion change, a common way of achieving a change in behavior is to use fear appeals and scare tactics. Earlier studies have shown that messages prompting a low level of fear can be more effective than messages prompting a high level of fear, since a high level of fear tends to raise defense mechanisms in the consumer. The purpose of this essay is to examine whether fear and defense mechanisms is a problem when it comes to making consumers choose organic products, as well as studying whether messages prompting low levels of fear are more effective than those prompting high levels of fear.This quantitative study is conducted in the form of a questionnaire-based experiment, comparing the effectiveness of two messages prompting different levels of fear.

Jämförelse av olika presentationsteknikers inverkan på precisionsbedömningar gällande avstånd i virtuella och verkliga miljöer

Denna rapport behandlar skillnader i bland annat visuell information (som olika djupledtrådar) vilka kan ha betydelse för den visuella upplevelsen och inverkan på till exempel precisionsbedömningar gällande avstånd i både virtuella och verkliga miljöer.Rapporten lyfter fram tre olika presentationstekniker som presenterar visuell information i olika utsträckning. Två av presentationsteknikerna, Desktop och CUBE, presenterar två virtuella miljöer. Den tredje presentationstekniken, Verklig, presenterar en verklig miljö. De tre presentationsteknikerna ställs mot varandra i en undersökning gällande eventuella skillnader i precisionsbedömningar (avståndsbedömningar mellan och på olika objekt). Resultatet visar att det föreligger signifikanta skillnader vad gäller precisionsbedömningar mellan den virtuella presentationstekniken Desktop och Verklig samt mellan den virtuella presentationstekniken CUBE och Verklig.

poäng IKT i ett projektbaserat arbetssätt ? en jämförande studie av informationssökning som social praktik

Our study emanates from a socio?cultural perspective on learning and aim to describe and comparetwo different upper secondary school classes and their work with information literacy as a socialpractice in project work and their use of ICT (information and communication technologies). Thequestions at issue in the study are; how the pupils handle information seeking processes, whatdifferences and similarities can be observed in the two social practices and which consequences thesedifferences have in an project work environment.Our choice of research methods to collect data consists of both observations and interviews withpupils and teachers. The interviews performed in the study can be categorized as qualitativeinterviews, and in addition we recorded and took notes during the interviews and transcribed thematerial.The study shows the importance of a good learning environment when it comes to working withinformation seeking processes, that the instructor?s role is of outmost importance and that the pupilsfundamental knowledge of information seeking processes and their information literacy are keysuccess factors when it comes to project work linked to ICT to be productive.

Produktutvecklingsprocessen : En djupstudie i hur ekonomer, designers och designchef samarbetar i en produktutvecklingsprocess.

Competition in the market of interior design during the last several years has drastically increased. The consumers of today are very conscious about what the market can offer and therefore they have high demands on the products. It is not only the function of the product that matters but also the design that makes a difference. Companies are becoming more aware of this and as a result they have to find a way to set themselves apart in order to attract customers. This realization has led designers and economists to cooperate in a different way than before.

Makten, skolan och Johnny

The workplace has a direct impact on the physical, psychological, economic and social well-being of the workers. A healthy workplace leads to increased health among the employees which also makes the employees more productive (Källestål, 2004). A poor working environment can have negative consequences for individuals, companies and society (SOU, 2009:47).This is a qualitative study that investigates companies? view of health promotion and how they practice health promotion in working life. Five private and five public companies, with representatives from the management were interviewed.

Är fytoremediering en realistisk metod för att rena marken runt Glasriket på arsenik, kadmium och bly?

Phytoremediation is a technique using the ability of plants to absorb pollutants in their biomass from contaminated soils and remediate it. The plants are then harvested and the soil gets purified. This method is more environmental-friendly than the normally used methods for soil remediation. Glasriket in Småland is an area with large amount of pollutants including arsenic, cadmium and lead. This area must be cleaned from these metals because of the high threat to the environment ant the health of people who live here.

Psykosocial arbetsmiljö : En arbetsgivares respektive arbetstagares ansvar för den psykosociala arbetsmiljön 

Arbetsmiljö är ?summan? av både fysiska, sociala och psykiska upplevelser som en arbetstagare möter i arbetslivet. Dessa upplevelser skapas eller formas av olika faktorer som arbetstagaren dagligen möter på sin arbetsplats. Då psykosocial arbetsmiljö idag är en relevant och aktuell fråga är uppsatsen inriktad på detta ämnesområde.I uppsatsen framställs den psykosociala arbetsmiljörätten ur tre olika perspektiv - rättsdogmatiskt, historiskt och empiriskt. Det rättsdogmatiska perspektivet är grunden för uppsatsen då det undersöks hur den psykosociala arbetsmiljön regleras i arbetsmiljölagstiftningen, samt vilket ansvar arbetsgivare respektive arbetstagare har gentemot den psykosociala arbetsmiljön.

Arvets betydelse för mjölkkors beteende :

It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.

Återuppbyggnad av en kollapsad stat - En fallstudie av återuppbyggnaden av staten Afghanistan

The purpose of this thesis is to explore and analyze the processes and efforts involved in rebuilding the war-torn state of Afghanistan. The examined period span from the fall of the Taliban regime in 2001, to the elections in 2005. This period, commonly known as the Bonn-process, sets out the initial time for the reconstruction of the state.A theoretical framework, which considers the necessary mechanisms for successful state-building, will be used to analyze Afghanistan's re-building process. The mechanisms include the prerequisite of a stable security environment, emerging from a cease-fire, together with the development of a well-functioning economy, re-introduction of rule of law and rejuvenating civil society.The failure to establish a secure environment has had a devastating impact on all analyzed aspects of the re-building process. It is therefore crucial that the international society continuing to assists the Afghan government in its efforts to strengthen its capacity, in order to improve the security situation.

Interorganisatoriska interaktioner inom Inkubatorer : En studie om kunskapsutbyte och inkubatorsystem

BackgroundIncubators are important facilities for economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.
