Grön kemi och hållbar utveckling : Laborationsdesign för gymnasium och högskola

This thesis is about sustainability within chemistry, the so-called, green chemistry. With this work  I seek to combine green chemistry with sustainable  development  and find methods for teaching green chemistry in a laboratory environement.  I have designed  and tested two labs with ingredients of green  chemistry and sustainable development in my study. I wanted to determine if my design model  leads to conception for the students. The students have through forms and interviews declared their perspective on the education and their conception. In a laboratory environment the pros of a laboratory way of work should be recognized.

Det löser sig! : Förberedelsens betydelse för gymnasieelevers lärande vid kemilaborationer

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

Genetisk artbestämning och karaktärisering av Trypanosoma theileri

Global warming is one of the most debated environmental issues right now, and it could be argued that it is important to study how the phenomenon is treated in schools. 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..

Revision av miljöledningssystemen i statliga myndigheter : Utvärdering av ett verktyg i det systematiska miljöarbetet

The Swedish government decided in 1996 that the governmental authorities are to implemementenvironmental management systems. Each year, the Swedish Environmental ProtectionAgency compiles the authorities? reports on their environmental management systems. Thecompilation shows that not more than 20 % of the authorities perform environmental audits.This study aims to investigate the authorities? view of internal environmental audits, the incentivesof performing them.

Miljödiplomering av HV71

This report is a degree paper made for the Engineering program in Technical Chemistry at the School of Engineering, Jönköping University.The intention of the project which is described, is to answer whether HV71 might become environmentally certified according to the criteria of "miljödiplomering". The project also included an investigation of which further steps and measures must be undertaken by the enterprise in order to achieve the certificate. The final part was to implement the necessary requirements for the certification.The report starts with a short background where the origin and function of environmental management is briefly explained.The report continues with how the practical work with the environmental certification was done according to requirements of Jönköping municipality. Motivations behind each part of the process are given as well as explanations of how each part of the process was carried out.The final result of the project was that HV71 took the measures needed to live up to the required demands. After a revision made by Miljöstrategen i Jönköping AB, HV71 passed the demands and became thereby an environmentally certified business..

Case Pöyry Sweden AB : Miljöprestandaindikatorer för ett tjänsteföretag

The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.

En kvalitativ studie av lärstrategier och perceptionsmodeller inom kemiämnet på gymnasie- och högskolenivå med fokus på de laborativa momenten

The aim of this study is to investigate how chemistry teachers at secondary school anduniversities work with learning strategies and models of perception. This thesis leans on theworks of Lev Vygotskij and his likes but also on the theory of conceptual metaphors by GeorgeLakoff and Mark Johnson as a tool to analyze the collected data.The Empirical data that this study is based upon have been collected through semi-structuredinterviews with teachers as primary respondents.The study has resulted in a two practical assignments for secondary school which are builtaround the concept of open assignments. This thesis has also generated a suggestion for a newstructure of the bachelor programme in chemistry at KTH..

Tillämpningar i kemiundervisningen : en studie av strategier för att presentera och synliggöra tillämpningar

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.

Varför miljöredovisning? : en undersökning av lastbilstransportbolag

Environmental work in preschools : three case studies in Uppsala

Environmental issues are global problems and they are a major challenge for any successful organizational business worldwide. Many challenges and opportunities emerge during the certification process of an EMS. Therefore it is interesting to contribute in understanding these emerging problems during this process.The aim of this study is to explore how the environmental objectives could be achieved at preschools in Uppsala, investigate the perceived challenges and opportunities and to identify the outcome of implementing the ISO 14001, Green Flag at such set up.A qualitative method is used and three Green Flag certified preschools, affiliated to the Uppsala Municipality and located at different geographical location were selected. A structured interview with the environmental representatives from the preschools and the municipality was completed. The so-called PDCA-cycle as a method of evaluating sustainable development and analysing the imperial data is used.The study showed that environmental certification constitutes a great challenge for the municipality of Uppsala.
