The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem?The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don?t put much energy to understand the problem before trying to solve it. They have no strategies.

AbstractBy finding out the pupils' choice of strategies for problem solving, we as teachers, can get a better understanding of their way of thinking, and thus also help them develop in their learning of mathematics. In a classroom environment where several different strategies could be found, the pupils' learning is facilitated as they, with the help of classmates, find positive and negative attributes of different kinds of strategies. The pupils are, in other words, each other's resources, rather than competitors. The main point is that the classroom environment, as well as the role of the teacher in the classroom, are both key elements for good mathematics learning.In order to increase the understanding of the pupils' choice of learning strategies, a survey was performed based on two school classes, one third grade and one six grade class at the same school. Both classes received the same mathematical problem to work with, and the strategies observed were analyzed and compared.

This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.

The aim of this study was to design short interventions based on the literature study, which will change the pupils? posture on mathematics and connections between problem-solving in mathematics and everyday life. An experimental group of 17 pupils in fifth grade participated in the study and were educated in everyday mathematics 20 minutes a day during four weeks. The intervention was measured in a pre- and after questionnaire, in order to control the design and discover possible changes in the pupils? posture on mathematics and connections between problems and everyday life.

Title:Knowledge system - a new way of observe the company Authors:Malin Pärmborn och Susanne Gidlöf Tutor:Anders Nilsson Department:Department of Business and Management Blekinge Institute of Technology Problem:How can processes of problem solving in a project contribute to generation of organizational knowledge in a knowledge company? Course:Master thesis in Business Economy Purpose:By describe the processes of problem solving in two different projects of our two chosen knowledge companies, we will clarify whether problem solving contributes to the generation of organizational knowledge. The purpose of this research is to increase the management consciousness concerning everyday processes that will contribute to the creation and transfer of knowledge. This is a condition to transfer human capital to structure capital and thereby decrease the company?s vulnerability. Approach:We gathered the data we needed through conversations and interviews with people on the two knowledge companies.

The purpose of this project was to investigate whether it was possible to develop a type of application, where users would solve chess problems. The main goal of the project was that there would exist an functional application after the study has ended with which users could solve chess problems on a computer. One subgoal of the project was to create corresponding application for mobile phones. The study was limited to require users to have at least Internet Explorer 9 +. For other browsers, there were no corresponding limitations.

Scania Top Team is a competition where the best mechanics in the world are competing against each other. In 2011, the world final was recorded and this material is now used to see which problem solving strategies these top of the line teams are using to solve the realistic problems assembled in front of them. To help them, the mechanics are allowed to use two of Scanias IT-systems: Scania Multi and Scania Diagnose and Programmer 3. This report consists of two parts. The first part is the development of a method to analyze the recorded material.

The purpose of this study is to portray conflict managing associated with children in a small class and what problems they may face each day at school. What types of conflicts and what consequences do teachers practice? This study is based on these following questions:Is there any difference for solving/measure for students with psychosocial problems or ADHD in a conflict or does teachers still works with the same methods?What types of conflict solving does schools use?What is important to consider with students in a small class who has psychosocial problems and ADHD to prevent conflicts?Summary: To answer my questions in this study, I´ve used qualitative methods, interviews and observations. I have used my cellphone for recording the interviews so that all content from the informers are accurate. My theoretical points concerns on having strict rules both inside and outside the classroom.

Syftet med studien var att ta reda på vilka strategier elever väljer när de ska lösaett matematiskt problem. Vi genomförde en observation och nio individuellaintervjuer med elever i årskurs 3. De fick lösa ett matematiskt problem somobserverades. Utifrån elevernas lösningar genomförde vi sedan intervjuer för attta reda på vilka strategier de valt att använda för att lösa problemet. Resultatet avelevernas lösningar visade på flera olika lösningsstrategier.

The purpose of this paper is to create increased understanding of how pupils learn statistics. This includes gaining insight into pupils' use of their own experience and group experience to help to get a better understanding of statistical problem solving. The study's research questions are about how pupils learn to work with data in tables and diagram and how pupils learn to work with measures.The theoretical framework consists of two approaches to studying learning. One approach is based on pupils? cognitive conditions, called set-befores, and the pupils' previous experiences, called met-befores.

The aim of this study was to describe how nurses cope with their daily stress at work. A literature review was made to answer the research question, data was gathered from two databases; Academic Search Elite and Medline (via Pubmed). The result which was based on 20 scientific articles showed that nurses used problem-focused and emotional-focused coping strategies to deal with the stress at work. Most of the nurses used emotional-focused coping strategies by practise some kind of physical activities, avoid and take distance from the problem. Using these strategies was negative correlated with burnout and psychological health.

Guazuigua is a small village in Bolivia, which has had too small water resources, especially for irrigation. A project started after some studies were made, to create a canal to provide the village with water from a nearby town. To make the canal work it had to cross a dried out river. There have been several attempts to cross these dried out rivers, but with poor results. The purpose of the report is to provide a solution for this problem.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.
