This study aims to highlight and analyze eight secondary teachers' views and thoughts on mathematics. Hopefully this study will provide a deeper understanding of how teachers think and reason about their subject and how this affects their teaching. The study was conducted using a qualitative interview method, based on interviews with eight middle school teachers who teach in school mathematics for grades 6 - 9. The interviews were recorded and then transcribed and analyzed. After the interview analysis one can conclude that the teachers? thoughts concern three main themes: the importance of mathematics, children?s lack of basic knowledge and the teachers? lack of time.In discussion and analysis the teachers conceptions of the own subject is being analyzed, and that is the foundation of this study.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

This survey is a case study with the purpose to find out the teacher´s perceptions about students´ motivation to mathematics. Further this study aims for the teacher´s vision on how they consider students´ motivation in mathematics in secondary school. To collect research data I have used semi structured interviews with four secondary school teachers. The result constructs according to categories that depict the purpose of the study. These categories define students? motivation like achieving different goals, students? basic knowledge, abilities and perceptions of mathematics and external factors that affect students? motivation.

This paper investigates the methods used by teachers when teaching elementary mathematics to children with Swedish as their second language. The original mathematical terminology derives from Latin, Greek and Arabic, this terminology is not of great importance in this paper, the everyday language spoken in elementary classes when teaching mathematical concepts and calculations to younger children is. The use of everyday language is an advantage for children with Swedish as their second language as mathematical problems presented in a more plain language is easier to comprehend and solve than problems in mere numerals. Special teachers in home language classes often have the task of clarifying the mathematical concepts, introduced to the children during mathematical lessons, in the pupils first acquired language. A qualitative method was used in this study.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

The purpose of this study is to see how some teachers in primary school creates and adapts their mathematics teaching for students with special mathematical abilities. It also aims to identify opportunities and challenges that teachers see in creating a teaching adapted to these students.In this study, qualitative interviews has been done to collect data. The interviews were conducted with five teachers who all are active in the primary school.The study results show that there is great variation in how the interviewed teachers create their mathematics teaching for students with special mathematical abilities. The use of mathematics book proved to be significant for how this adaptation took place. The result also shows that the teachers? explanations for the choice of the adaptations that they make in teaching vary.

The purpose of this study is to gain a deeper understanding of how teachers and other people working with mathematics in a school context perceive inclusion in terms of education. In addition,the purpose is to describe their experiences of inclusive education in mathematics and to identify factors of importance for an inclusive approach to teaching mathematics. The starting point was the significance of inclusive education as regards the education system and research on the implementation of inclusive education internationally and in Sweden. The theoretical approach is founded in a special education perspective on teaching and the theory of optimal experience. The people interviewed for this study are directly or indirectly involved in the teaching of mathematicsat a school that explicitly works from an inclusive perspective.

Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.

The aim of this study was to examine if there was a relative age effect in students grade in mathematics. The study was built on regression analysis and Spearman rho on student?s month of birth and their grades. It was found that there is a relative age effect in the student?s grades.

This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

The purpose of this thesis is to try to find out what effect subject oriented projects like Energiutmaningen has on the teachers, with a focus on teachers? physics education. What was the experience for the teachers who participated and what effects did the project have on them. Four teachers were interviewed through qualitative interviews. From the result it showed that the most experienced teachers, who have been teaching physics for many years, gained a new perspective of their teaching, through their participation a development showed in their education.

This study aims to provide a comprehensive understanding of interdisciplinary collaborations between Art and Mathematics within the Arts program at the upper secondary school level. Grounded in sociocultural theory, this study explores learning through language, action, and context, drawing on the works of theorists such as Lev Vygotsky (1995/2016), John Dewey (1897/2011) and Roger S?lj? (2020). Through semi-structured interviews, educators in both Art and Mathematics discuss shared subject content and explore opportunities and obstacles in fostering a collaborative culture within the Arts program at the upper secondary school level. The study reveals common subject content in Art and Mathematics suitable for interdisciplinary collaboration.

The purpose of my study is to examine how four preschool teachers go about using the term play in children's early mathematical development. In order to fulfill the purpose of this study, I have the following questions:How the preschool teachers visualize mathematics in children?s play?What reflections have the preschool teachers about the importance of play for children's mathematical learning in preschool?How do the preschool teachers see on their own role in the children's play?In this study, I have conducted a semi-structured qualitative interviews based on the interviews with four preschool teachers from various departments in a preschool. I have also conducted some observations to complete my study. Whereas in my analysis of the researched material, I have used Vygotsky's theory.The survey shows that the preschool teachers are aware of the use of mathematical language and concepts in children?s different activities which were conducted daily in the preschool.
