The main purpose of this study is to put students? knowledge about global warming in relation with the control documents for chemistry, biology and physics studies. Interviews have been conducted with six students in the 9th grade. The conclusion of the survey indicates that the students generally have a satisfying knowledge about the phenomenon and that they know how they should behave from an environmental perspective..
Hur uppnår vi god inomhusmiljö i förskolan idag?
Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

Enhetschefsposition - Utmaning eller huvudvärk? : Middle Management - A Challenge or a Headache?
AbstractThis is a qualitative study on what motivates personnel to apply for middle management positions within the Värmland County Police Department. This study also looks at whether or not there are differences in motivation between men and women in regards to applying for middle management positions.The study has been conducted through in-depth interviews with 17 employees of the Police Department. The material collected was analysed using the Empirical Phenomenological Method (EPP). 29 categories were generated which were then divided into four themes.The result showed that motivation can be achieved by having a more structured middle management roll whereby, for example, there are clear guidelines on the responsibility and authority you have. Support and encouragement were also named as motivating factors.
Från snopp till kropp : En c-uppsats utformad inom sex och samlevnad
Detta är endast en del av ett stort arbete, på grund av omständigheterna (till exempel möjligheten att publicera en power point) har vi varit tvungna att begränsa vår publikation till lärarhandledningen. Det finns också en elevutgåva, power point-presentation samt ett prov som inte publiceras. För att ta del av dessa krävs möjlighet att komma åt Biologi C för lärares kurswebb Vt-2008 på Södertörns högskolas intranät. .

Påverkansfaktorer i biologiundervisning : En intervjustudie om faktorer grundskollärare upplever påverkar genomförandet av biologiundervisning i årskurs 4-6
Både internationella och nationella kunskapsundersökningar visar att svenska elevers kunskaper i naturvetenskap har försämrats under flera årtionden. Svenska elever presterar relativt bra i naturvetenskap i årskurs 4 men det sker en kraftig förändring när eleverna går i årskurs 8. Intresset bakom studien är därför att se hur den svenska biologiundervisningen genomförs i årskurs 4-6 eftersom elevernas inställning och kunskaper försämras efter dessa årskurser. I läroplanen framhålls ett antal förmågor inom vardera skolämne som eleverna ska utveckla i grundskolan. I biologiämnet finns tre förmågor och den förmåga som jag upplever är viktig för att bibehålla intresset för ämnet handlar om att eleven ska kunna använda biologins begrepp, modeller och teorier för att beskriva och förklara biologiska samband i människokroppen, naturen och samhället.I studien har nio grundskollärare intervjuats för att urskilja faktorer de upplever påverkar elevens möjligheter att utveckla förmågan.
Arbetshanteringen på godsmottagningen hos EFG
The aim of this report is to investigate how the work handling at the department for arriving goods at EFG in Tranås is working, as well as how it could be improved and made more effective. EFG is a corporation who process and sell office furniture. The company is working with a project concerning delivery precision, the subject is therefore particularly interesting from the perspective of delivery accuracy. The number of orders has increased notably during the fall of 2005 and the spring of 2006. This has led to new demands at the department for arriving goods and the topic is as a result of that important also from this point of view.Interviews and investigations have been conducted at location since no written material earlier has been made in the topic.

Kollegialt lärande : En studie av lärare som arbetar utifrån en modell för att utveckla sin undervisning
Syftet med studien är att undersöka vad lärare samtalar om när de deltar i kollegiala träffar enligt NTA Skolutvecklings modell för att förbättra sin undervisning främst inom de naturvetenskapliga ämnena biologi, fysik och kemi. Syftet är också att undersöka handledarens roll vid träffarna, vad som händer i klassrummet mellan träffarna, identifiera möjligheter och hinder för kollegialt lärande samt få ökad förståelse för lärares forskningsanvändning.Studien utgår från kvalitativa forskningsmetoder och material till studien har samlats in genom deltagande observation, transkribering av filmning, samtal, insamling av data och enkät mm. Jag har noggrant och systematiskt bearbetat insamlat material och fördjupat mig i forskning om ämnet.Min undersökning visar att lärare som deltog på dessa träffar var fokuserade på träffens tema. Fokus i samtalen ligger på lärarens egen undervisning och de egna elevernas möjligheter till lärande. Lärarna diskuterade dilemman i klassrummet och reflekterade över händelser i klassrummet.
Föräldrars upplevelser av mångbesök på barnakutmottagningen
Introduction: Frequent attenders is a term used in health care services that define a person attending a health care setting more than four times during a 12 month period. Recently published research concerning frequent attenders in pediatric emergency departments describes their reasons for attending a health care service or characteristics of these individuals but lacks a qualitative approach exploring their experiences. There is a need of these experiences to be shared so that health care personnel caring for this group may gain a greater understanding of their needs and expectations.Aim: The aim of this study is to describe how parents of children defined as frequent attenders experience the care received at a pediatric emergency department.Method: Qualitative approach with semi-structured interviews. A pilot study of four interviews was conducted to test the method. Sampling consisted of parents of children defined as frequent attenders and that were not diagnosed with a chronic illness.
