Elevers perspektiv på bedömning för lärande
The aim of this study was to examine the students' perspectives on formative assessment, partly about how students perceived the assessment in general, partly about what students' opinions were on formative assessment, and partly about students' view of how assessment could be organized to stimulate learning process. The study consisted of qualitative interviews with six students in grades one in an upper secondary school.The survey showed that students primarily perceived assessment with summative purpose: tests and scores. Majority of the students experienced that there were too many tests occasions. Those high-performing students were positive to tests. However, those lower-performing students felt more negative and became more stressful with the exams.Results showed that they were lack of experience of formative assessment. All the six students thought that they had not got any chance to involve in the assessments process. They realized that they had not got adequate feedback about their learning-situations. With regard to students' wishes about how assessment could be developed in order to improve their learning, it was mainly about more and concrete feedback on tests and assignments.Two models were developed in the final discussion, which showed the author's own perception of formative and summative assessments..
Riktar sig nationella proven till alla elever? : En kvalitativ studie av några lärares upplevelser av arbetet med de nationella proven med elever som inte har svenska som modersmål
The purpose of this study is to illustrate how some teachers in multicultural school environments reflecton and experience the educational work with national tests in the third grade for students who do not have Swedish as their native language. The research questions I have chosen to work with are:How do teachers experience working with national tests in groups of students where there are children with Swedish as a second language?How do the teachers reflect on the students linguistic preconditions relating to the national tests in these groups of students?What strategies in their teaching on national tests do the teachers use when it comes to students with Swedish as a second language?In this study I have chosen to use a qualitative interview method. Since the purpose of the study is to understand how teachers reflect on students with Swedish as a second language the obvious choice was to interview teachers who work in a multicultural school. In my thesis I have chosen to use sociocultural theory, Cummins four quadrant model and context for theoretical approach.
Matematiska arbetsmetoder : En kvalitativ undersökning om undervisningsmetoder i förhållande till nationella matematikprov
The purpose of this study is to provide a description of how mathematics teachers in grades 3 choose to work with mathematics and how it affects of student performance in national tests. The categories I will use are outdoor education, textbooks, learning materials and problem solving. Laboratory materials can be everyday materials and educational materials in which pupils have an abstract understanding of the subject. This survey was conducted through interviews and observations. The survey was also conducted in relation to student performance in national math tests.
Granproduktion på tallmarker! : är produktionen hållbar?
The aim of this report was to investigate the hypothesis that Norway spruce (Picea abies L. Karst), planted on poor ?Scots pine? stands will not have sustained growth during the whole rotation, due to water deficit in the closed stands. In order to investigate this hypothesis, data from 10 Norway spruce stands in southern-eastern Sweden were collected. In 10 plots in each stand, diameter and breast heights were measured on every tree.
Valet av hög revisionskvalité : Vilka faktorer beskriver valet?
This paper analyzes the auditor choices for a sample of 300 predominantly small Swedish firms, all located in Umeå. Our hypothesis was based on the complexity of a firm, the need of external financing, leverage, and the need of extra consultance from the auditfirm. Our definition of auditor quality is based on prior studies, and is frequently used by authors in this area. The assumption is based on that the auditor quality increases with the size of the auditfirm and the degree of the auditor. The auditor quality is therefor depending on the choice between an auditor from the group ?Big 5? or not, and the choice of an auditor with an higher degree.
C, C++, Java och Python - En prestandajämförelse mellan fyra programmeringsspråk
In today?s society computers are getting a much more important role. To get a
computer to work
as intended it has to be programmed. A computer program is written with
programming
languages.
There is an abundance of programming languages available today and there are
many
differences and similarities between them. The different languages have their
advantages and
their disadvantages where some of them are intended for fast performance, some
to be cheap
on memory usage, and some are developed to be easy to program on.
In our thesis we have chosen to compare four of todays most common languages,
C, C++, Java
and Python.
Energieffektivisering i flerbostadshus : En studie av incitament och hinder i Uppsala
The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.
Kan instruktioner om en rättvis och likabehandlande rekrytering leda till minskad diskriminering?

Att få vara med och skriva manus : Att motverka traditionella könsroller genom dramapedagogik i förskolan
The purpose of this thesis is to study how preschool teachers can reach the goal of the swedish educational plan to prevent traditional gender roles for children ages 3-6 through drama in education.This is answered by four hypothesis based on Judith Butler's queer theory, George Herbert Mead's social psychological theory and Gavin Bolton and Dotothy Heathcotes drama pedagogical theories. The hypotheses are tested against four teachers' examples of their work.The hypotheses areHypothesis 1: By using the expert's mantle and active observation in teacher-in-role indrama educational exercises, we can see how the children internalize the heterosexualmatrix and the outline of the internalized other.Hypothesis 2: By using the "mistakes" that occur when children repeat performativeacts that do not fit with the heterosexual matrix, these other possible behaviors can bestrengthenedHypothesis 3: Through drama exercises that are not normative teachers can widen theheterosexual matrixHypothesis 4: Through drama pedagogical methods like teacher-in-role teachers canprovide possibilities of other performative acts and the creation of a more tolerantinternalized other.The analysis show that the respondents work within all these hypotheses in different ways and thathypotheses 2 is the one with the weakest support in the interwievs. The examples are also weakregarding the use of Boltons drama pedagogical methods, but that there are a number of othermethods in use.Some of the conclusions are that more theoretical knowledge in the preschool drama pedagogics tocounteract traditional gender roles and patterns, as well as the drama of educational theory need tobe linked to queer and social psychology research. There is also no monitoring of the long term effects of the work..

Att sätta fingret på emotionell intelligens - En kvalitativ studie om användningen av EQ-test i rekryteringsprocesser
Emotional intelligence (EQ) has been claimed to be the most critical factor in determining a person's success in life, both personal and professional. EQ highly affects academic and job performance, leadership, stress, and well-being but is still not widely accounted for in recruitment processes. During the last 20 years a large number of researchers have shown interest in the concept of emotional intelligence, but few have studied its practical implications and how EQ-tests are used as a selection tool in recruitment processes. To create an understanding of the motivation for using the test, as well as its role in recruitment decisions, qualitative interviews have been conducted with recruiters at companies in Stockholm, Sweden. All interviewed companies use the self-assessment test EQ:i 2.0.
Kortsiktighet i näringslivet : En studie om förhållandet mellan VD, styrelsen, ersättning och avkastning
This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.
