Concentration problems have been discussed from a variety of angles and have been problemized in different ways. One approach is to place the major part of the problem on the child independent of its environment. The terms used as an explanatory model are ?attention disorder, impulsiveness, difficulty at finding suitable activity levels, difficulty in understanding rules and instructions? (Kadesjö 2007). Others place the root of the problem in the environment prevalent at pre-school and school.

In Sweden there is a long ongoing discussion about computer and cellphone usage during lectures in school. The discussion has mainly covered elementary school up to college students, but this topic is at least as relevant for university students. Today cellphones are so advanced; you can do everything with one that you previously only could do with a computer, the difference is that everyone is carrying one with them all the time. This study shows how concentration during lectures is affected by the cellphone accessibility and usage. With this study we want to find out how university students perceive cellphone usage affects their own concentration during lectures.

The purpose with this study was to see the relation between gymnastic pause and concentration to find out the students in a first grade experiences and thoughts about gymnastic pauses in the classroom. I have made a qualitative study to fulfill my purpose, I have observed students before and after the gymnastic pauses, carried through gymnastic pauses with the pupils and interviewed pupils in group.Previous research shows that the good working atmosphere and concentration has improved when pupils have had gymnastic pauses but it is difficult to say how it looks in the long term when the research doesn?t show that.In my study, it appears that the gymnastic pauses make it calmer in the classroom. Some of the pupils believe that they have had a better ability to concentrate after the gymnastic pauses while some pupils believe that they have not had a better ability to concentrate. Some pupils say it's good to get a break to carry on with the schoolwork during the entire lesson.

Background·ADHD  is a syndrome characterized by attention deficits, difficulty of concentration, restlessness and lack of control. The number of persons diagnosed with ADBD have increased over the past few years. One reason for the increase is believed to be that the knowledge has increased in recent years and more persons can be diagnosed . As a nurse it is important to know about ADHD and how it affects the persons with it.Aim. The purpose of this autobiography study was to describe the experience of adult persons living with the disability ADHD.Method.

The study evaluated the Mutant Prevention Concentration (MPC) of Pradofloxacin on three Escherichia coli (E.coli) strains, 2 wildtypes and one first-step gyrA resistant mutant. We also measured the value of AUC (Under the Concentration)/MPC that prevents growth of resistant mutants. It is of importance to reach a concentration above MPC that prevent E.coli from developing resistance against the antibiotic.We used an in vitro kinetic model where we added bacteria? and antibiotic. The culture flask was attached to a pump with an adjustable pump-speed.

The purpose of this study is to gain a deeper understanding of how preschool teachers are doing to train children with concentration difficulties to maintain their concentration. That children with concentration difficulties increases is something that emerged in this study. In order to facilitate and help these children in the best possible way, you have to know the underlying causes and the factors that contribute to lack of concentration.Iam usinga qualitativeinterview method withsemi-structuredquestions to getanswersto my questions.Threeteachers fromtwodifferent preschoolsparticipated in the survey. What emerged in the study was that large groups of children, long days at preschool and today?s society with stress are major causes contributing to the increasing number of children with concentration difficulties according those interviewed. The teachersworkedprimarilyonan individualizedmannerin which theyassumed thatallchildrenare different andreact differently to theimpressions andstimulipresent in the environment.

Children with concentration difficulties are to a great extent a problem in schools and therefore it becomes interesting to see how possibilities around these children can appear in pre-school. From a pre-school teacher?s perspective, the study aims to provide a deeper understanding of how outdoor education can influence children with concentration difficulties. The method of the study is a qualitative research run-up with interviews that intends to describe pre-school teachers? views.

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

This scientific essay is based on four self-perceived situations that all takes place in an outdoor environment. The children are aged seven to nine years. At least one of the children in the groups has some type of concentration difficulties. I have combined my practical experience with literature and previous research regarding outdoor education and children with concentration difficulties. Based on this I have tried to interpret and reflect on the opportunities and problems with outdoor education for children with concentration difficulties, especially so called situational concentration difficulties.

This project has aim to examine how students experience their concentration ability during mathematics lessons in the mornings and afternoons, and how students? learning can be in-fluenced by the concentration ability during mathematics lesson in the morning and after-noons respectively? Which role do the methods of learning play in mathematic depending on which time it is carried out during mornings or afternoons with regard to student concentra-tion ability? In order to find out those issues, I used two methods; (interview and observa-tion).Interview with 4 students and 3 teachers and observations of 4 mathematics lessons based on a qualitative method. In order to measure students' concentration ability during ma-thematics education on various times, I distributed questions to 23 students and repeated it during each lesson that I have observed from a quantitative approach in two classes in a sec-ondary school. In the literature I discuss the definition of concentration, and factors affecting the concentration negatively and positively. What is the relationship between concentration, learning and type of activity and how individuals can improve their learning and attention? In addition I studied two earlier studies on the concentration.

In school today pupils come in contact with all kinds of reading books. Education of Swedish reading development sometimes contain reading books organized at different levels of difficulty, with different amount of text. The purpose of the different difficulty levels is to give the less skilled readers an easier book and stronger readers a more difficult book. The purpose with this study is to find out if the book which is classified as more difficult, in reality is the most difficult and if the book which is considered to be easier really is. To find answers to these questions I will examine previous researcher?s theories on difficulty levels in reading books.

Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.

The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.
