The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.

The purpose of this study is to investigate how teachers approach communication in their mathematics instruction. The communication involves concepts such as teachers' mathematical language, incorrect answers, and various interaction patterns. In line with this, the study also examines how these types of communication may affect students in the classroom. Furthermore, observations and interviews were conducted with five different teachers in Sweden using an observation scheme and an interview guide. The results reveal that four out of the five teachers use both child-directed and adult-directed language when addressing students at different levels of mathematical understanding.

The aim of this thesis is to examine how the history of mathematics can be used in teaching and whether pupils? attitudes to mathematics can be affected by this. In order to do this a school project about the history of mathematics is planned, implemented and analysed.The following questions are addressed:? Why use the history of mathematics in teaching?? How can the history of mathematics be used in teaching?? Can a historical perspective in teaching affect pupils? views on mathematics?The school curriculum emphasizes the importance of history in teaching. Literature, scientific articles and government inquiries call attention to the positive effects of including a historical perspective in teaching.The school project, which underlies this thesis, is put to practice by 25 pupils in a mathematics science profile class.

During my practice as a teacher trainee at an upper secondary school it became clear to me that many pupils had difficulties with mathematics. I was surprised to find that many pupils seemed to get stuck on the level of attainment for the senior level of the nine-year compulsory school. As I have not studied anything about difficulties in Mathematics during my training to become a qualified teacher, I would like to get to know more about this.After studying research done on this subject I made the following approach to the problem:? What fields regarding Mathematics do the pupils themselves find most difficult?? What factors have been contributory causes to these problems?? What are the factors that have helped pupils with difficulties in Mathematics to reach the goals for the syllabuses in Mathematics?The answers to my questionnaire and interviews resulted in the following conclusions:? Pupils find theory of equation and conversion of units as most difficult at senior level of the nine-year compulsory school.? Teaching should be done in special instruction groups to give the pupil the opportunity to develop his/her skills on an individual level.? Pupils find it hard to deal with all moments in Mathematics during the time given for each course.? The pace for teaching Mathematics is too high according to the pupils.? Pupils wish for instructions on a lower level.? There is often a lack of contact between teacher and pupil.? The teacher should use more time to help the pupil receive good self-confidence and increase the motivation for instructions in Mathematics..

This study examines how formal mathematics can be taught in the Swedish secondary school with its new curriculum for mathematics. The study examines what a teaching material in formal mathematics corresponding to the initial content of the course Mathematics 1c could look like, and whether formal mathematics can be taught to high school students.The survey was conducted with second year students from the science programme. The majority of these students studied the course Mathematics D. The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented with formal mathematics. This both in terms of requirements for content and students being able to comprehend this content.

Research indicates that a more hands-on education in mathematics could improve how students relate to mathematics. Laboratory mathematics is a way of making mathematics more concrete.  How is the purpose of laboratory mathematics perceived? This thesis has its focus on the pupils? perceptions of the purpose of laboratory mathematics, but the intention of the teacher involved is also investigated. The main research questions asked were:What is the teacher's definition of laboratory mathematics?Which is the teacher's purpose in using laboratory education?How do the students perceive the purpose of the laboratory teaching of mathematics?To answer the questions, I conducted a series of qualitative interviews.

The purpose of my study is to investigate teachers? opinions about learning difficulties in mathematics.I have read relevant literature on this subject. I have conducted interviews with seven class teachers, one special-needs teacher, a psychologist and one special-needs teachers who specifically worked with investigations concerning pupils with difficulties in mathematics.The result of my study shows that learning difficulties in mathematics can/might be prevented if children in pre-school are introduced to mathematics as early as possible. This should be done in a delightful way in their daily activities and while there are playing. I didn?t find any complete method to help children with mathematics difficulties in compulsory school.

Syfte: Syftet med studien är att undersöka sambandet mellan socioekonomiska faktorer, oral hälsa och oral hälsorelaterad livskvalitet. Material och metod: Det gjordes en systematisk litteratursökning som gav totalt 454 träffar varav 24 artiklar var relevanta. Artiklarna granskades efter relevans och kvalitet och inkluderades därefter i studien. Resultat: Socioekonomiska faktorerna inkomst, utbildning, yrke, social status, kön och etnicitet var associerade med oral hälsa, dock var inkomst och utbildning det som var mest korrelerat med oral hälsa. Sämre oral status kunde verifieras med klinisk undersökning som oftast undersökte antal tänder, karies och parodontit, vilket antogs kunna påverka oral hälsorelaterad livskvalitet.

This is an empirical study of how the mathematical talk of adult learners constructs/reconstructs different mathematical discourses. The study is to be regarded as an attempt to develop a discursive approach within the field of mathematics education and to complicate the status of mathematics in education and in society in general. My theoretical underpinnings consist of three possible mathematical discourses ? coercive, regulative and emancipative mathematics. From a discursive psychology perspective, I let these discourses function as analytical interpretive repertoires in relation to the adult learners? rhetorical use of mathematics and their claiming of mathematical subject-positions, named the coerced, the self-regulating and the responsible mathematician.

This study examines how formal mathematics can be taught in the Swedishsecondary school with its new curriculum for mathematics. The study examineswhat a teaching material in formal mathematics corresponding to the initialcontent of the course Mathematics 1c could look like, and whether formalmathematics can be taught to high school students.The survey was conducted with second year students from the science programme.The majority of these students studied the course Mathematics D.The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented withformal mathematics. This both in terms of requirements for content and studentsbeing able to comprehend this content. The curriculum also requires thatthis type of mathematics is introduced in the course Mathematics 1c.The results also show that students are open towards and want more formalmathematics in their ordinary education. They initially felt it was strangebecause they had never encountered this type of mathematics before, but somestudents found the formal mathematics to be easier than the mathematicsordinarily presented in class.The study finds no reason to postpone the meeting with the formal mathematicsto university level.

The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.

The school inspectorate surveys illustrates problems and difficulties for teachers to suit individualized instruction. Therefore, the purpose of the study to investigate whether and in what ways some pedagogues experiences and practice offers the individualized instruction that the governing documents require. The study is based on a qualitative method in the form of semi-structured interviews and observations with four experienced pedagogues. I have been using Piaget's theory of the concrete material's importance for learning and also Vygotsky's theory of the proximal development zone. The results showed that pedagogues understand the importance of individualized instruction.

The aim is to find out how teachers apply the knowledge they get from mathematics pilots in preschool and from mathematics developer in the municipality, as well as how they work further towards the children with mathematics.The study is based on qualitative interviews with two teachers, one mathematic pilot and one mathematic developer. I used the semi-structured interview questions.The results show that teachers believe that mathematics pilots will inspire the teachers in their work with mathematics in preschool. One of the teachers who were interviewed said:?Mathematics pilots should be those that have the strongest glasses and coming up with new ideas and they push the rest of the teachers in their work with mathematics in relation to children in preschool?.The teachers use the correct terms for mathematical concepts with the children. They also stressed how important it is to point out to the kids that it is mathematics that they are doing.The conclusion of the study is that the teachers agree that it is their approach towards the children that is important and how they can lead the children?s interest of mathematics forward.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
