In this study, the aim has been to investigate how different educational materials in the nature science subjects are designed with the intention of how many and what types of laboratory activities the pupils will encounter to contextualize the abstract nature of science to develop their understanding of the content and working methods of science. In order for the pupils to have the opportunity to develop a scientific understanding, it is necessary that they have the opportunity to use their senses to interpret the text that is presented to them. Through various sensual, experimental, and practical activities, pupils can gain an understanding of the abstract phenomena, concepts, and explanatory models of natural science. In today's schools, there are many teachers who use educational materials as their point of departure when teaching science. Educational materials have an important role in science teaching, but depending on how the educational materials are designed, they provide different conditions for learning. In this study, the number of laboratory activities, that appear in different educational materials for science teaching, is investigated, as well as whether these laboratory activities are designed in terms of their degree of freedom and openness. The following questions have been addressed in order to achieve the purpose of the study: - How many laboratory activities can be found in the various educational materials?-  Are there more laboratory activities in any of the three nature-oriented subjects, biology, physics, or chemistry? - What types of laboratory activities do the pupils encounter in the educational materials and what degree of openness and freedom do they include? The investigation has been carried out through a qualitative and quantitative text and content analysis where various educational materials have been analyzed based on the context-based learning (CBL) theory and the theory of laboratory classification. The results of the qualitative and quantitative text and content analysis showed that certain educational materials give the pupils more opportunities to connect the scientific content to real experiences. The results also showed that some educational materials have a greater variety of different laboratory forms where the pupils have the opportunity to develop an understanding of the different working methods and content of the natural sciences. The conclusion that can be drawn after this study is therefore that it is important that teachers carefully review the various2educational materials to gain insight into their design. Through insight into the design of the educational materials, the teacher can then supplement the educational materials with, for example, laboratories of varying degrees of openness and freedom to give the pupils the opportunity to fulfill the goals in the curriculum.

The engineering education has changed and evolved over decades in harmonywith societies challenges. Today, sustainable development is of great importanceand one way of equipping future engineers with the competencies to tackle these challenges is through Challenge Driven Education (CDE). CDE is a relatively new educational concept which brings together universities andexternal stakeholders to jointly foster the engineers of tomorrow. The research focuses on the challenge owner’s perspective, which is a sub-category of external stakeholder. The challenge owner could be a company or organisation providing the students with challenges and also takes an active role in the students path to solve them. Through qualitative interviews in Sweden and Tanzania this study investigates some aspects of the CDE concept and develops a product in the form of a guide.First, it was investigated which competencies for sustainability that could be considered important in future engineers, according to interviewees. It was also investigated which competencies were developed during CDE projects. Results show that UNESCO’s key competencies correlates well with interviewees views, justifying the legitimacy of the framework. However, some skills and attributes mentioned in interviews lie outside of UNESCO’s framework but where still considered important. This implies the need to supplement orevolve the framework in order to be a more comprehensive tool for improving CDE and the engineering education. Secondly, several differences on how CDE is portrayed and executed where found in the interviews. From the Tanzanian context a somewhat limited view of the challenge owner was identified and findings show possibilities of broadening the perspective of the challenge owner role. Also, findings shows a need to emphasise the importance of sustainable development and societal contributions in the future development of CDE. Lastly, in order to facilitate communication with potential challenge owners in future CDE collaborations in Tanzania, the need for a guide was identified. Using an iterative design method, a guide based on interviewees feedback and the findings from this study was created. The main purpose is to present a widened view of CDE and to inspire potential challenge owners to join. / Ingenjörsutbildningen har, i linje med samhälleliga förändringar, ändrats och utvecklats i årtionden. Idag är arbetet mot hållbar utveckling av hög prioritet och ett sätt att utrusta framtidens ingenjörer med kompetenser för att ta sig an dessa utmaningar är genom Challenge Driven Education (CDE). CDE är ett relativt nytt utbildningskoncept som för samman universitet och externa intressenter för att gemensamt fostra morgondagens ingenjörer. Studien utgår från de så kallade challenge owners perspektiv, vilket är en underkatergori till de externa intressenterna. Challenge owners kan vara företag eller organisationer som förser studenterna med utmaningar och som även tar en aktiv roll i studenternas arbete med att lösa dessa. Genom kvalitativa intervjuer i Sverige och i Tanzania undersöker denna studie några aspekter av CDE-konceptet och utvecklar en produkt i form av en guide:Först undersöktes vilka nyckelkompetenser för hållbar utveckling var relevantaför framtida ingenjörer enligt intervjupersonerna. Det undersöktes ävenvilka kompetenser som utvecklades under CDE-projekt. Resultaten visar att UNESCO’s nyckelkompetenser korrelerar väl med de intervjuades syn på vad som behövs, något som ger legitimitet till ramverket. Dock visar resultaten att några färdigheter och egenskaper som ansågs viktiga ligger utanför UNESCO’s ramverk. Det antyder att det finns ett behov att komplettera eller utveckla ramverket för att göra det till ett mer heltäckande verktyg i syfte att förbättra CDE och ingenjörsutbildningen i stort. I intervjuerna identifierades sedan flera variationer i hur CDE beskrivs och tillämpas. Från den tanzanska kontexten identifierades en något begränsad syn på vad en challenge owner är och resultaten visar på möjligheten att bredda synen på challenge owner-rollen. Resultaten visar också på vikten av att betona hållbar utveckling i CDE-projekt samt att CDE kan bidra till samhällsutvecklingen. Något som ansågs viktigt för att utveckla och ta CDE-konceptet vidare. Slutligen identifierades ett behov att underlätta kommunikation med potentiella challenge owners i framtida CDE-samarbeten i Tanzania. Genom att använda en iterativ design metod skapades en guide. Guiden är baserad på feedback från intervjudeltagarna samt resultat och slutsatser från denna studie. Det övergripande syftet med guiden är att presentera en breddad bild av CDE samt att inspirera potentiella challenge owners att engagera sig i CDE.
