Hur integrerar man föräldrarna i matematikundervisningen?

Syftet med detta arbete är att utforma ett material där matematikundervisningens mål och arbetssätt tydliggörs för föräldrarna; detta för att föräldrarna ska bli mer positiva till undervisningen och därmed påverka sina barn positivt. Vi har på två skolor i södra Sverige genomfört en enkätundersökning med 49 elever i skolår 4 och deras föräldrar. Undersökningen visar att föräldrar inte är insatta i matematikundervisningen, att de vill ha mer information om undervisningens mål och arbetssätt samt hur de kan hjälpa sina barns matematik-inlärning. Denna information vill de ha i form av brev och träffar. Vi har utformat ett material för hur informationsträff och ?brev kan läggas upp och vad de kan innehålla.

Teknik och barnböcker : hur kan tekniska system synliggöras genom sagoberättande

SAMMANFATTNINGDetta examensarbete är baserat på en uppgift från Small Domestic Appliances (småhushållsprodukter) på Electrolux. Arbetet har handlat om att få in mer naturliga materialmed ?premium? känsla i deras produkter, annat än plast och rostfritt stål.Materialundersökningen har inkluderat: glas, trä, keramik och dekorativa tillämpningarför metall och plast. Hur en användare upplever ett material har också undersökts.Information har samlats in i två undersökningar; en om trender, marknad ochkonkurrenter samt en om material, leverantörer, tillverknings- och ytbehandlingsmetoder.Tre subjektiva test har gjorts på taktilitet för att få reda på hur vissa material upplevs avanvändare. Testerna utfördes med hjälp av materialprover, frågeformulär ochtestpersoner.Ett objektivt test på friktion utfördes också där friktionskoefficienten mellan ett materialsyta och fingertopparna räknades ut.

Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.

Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad

This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..

Västergarns kammar : en fallstudie av Västergarnskammarna från seminariegrävningarna mellan åren 2006-2010

During the years 2006-2010 Gotland University conducted seminars excavations in Västergarn parish on Gotland. Inside the wall a total of six house foundations have been found and a total of 127 combs have been registered. This thesis is based on a material study of the 127 registered medieval combs. The purpose of this thesis is to analyze the combs and with their chronology illuminate in which period the society of Västergarn was active. And also to find out what the material remains can tell us about the place and its people.

Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Sensory nerve conduction studies in young adults for the expansion of a reference material

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

Slöjdens hårda och mjuka material alltmer sammansmälta : Samarbete inom slöjdens olika material, kan det utveckla ämnet?

Syftet med studien var att undersöka om slöjdlärarnas olika utbildningar spelar roll för samarbetet inom slöjdens mjuka och hårda material och hur ett sådant arbetsätt kan se ut. Undersökningen har även försökt få svar på om eleverna blir mer motiverade av ett arbetsätt där materialen blandas. Dessutom har arbetet handlat om att ta reda på om det finns ytterligare faktorer som spelar roll för samarbetet inom ämnet slöjd. Genom studier av tidigare kursplaner för ämnet i skolan och för slöjdlärarutbildningar har jag fått en historisk tillbaka blick för vad som ingått i både slöjdlärarutbildningar och i undervisning för eleverna i skolan. I mitt sökande efter svar har 8 slöjdlärare intervjuats som läst mot både tidigare och nuvarande läroplan för grundskolan och som har examen från utbildning med behörighet i ett eller båda materialen.

Att uppleva rum - ett utforskande projekt om rumslig gestaltning

This project in an in depth exploration about the basics of creating space in the form of an experimental investigation using my own perceptions as reference. Within a method, especially outlined for the project using descriptive words of opposites, my interpretation of the words has been formed into models of rooms. Four workshops with restrictions and rules acted as a platform for the striving towards the aim of a wider understanding of how space can be experienced. Through analysis I have formulated the different parameters influencing space itself and my perceptions of it. During the project a language for visualizing the interpretations of a room has been further evolved.

Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.
