When measuring people’s trust, research show a negative trend where people’s trust over time is declining globally, where digitalization is accelerating the process. Trust is a key component in a democratic society and social studies has the task of communicating democratic values and integrate the students in the democratic process. The aim of the present study was therefore to examine how different aspects of the concept “Trust” are highlighted and portrayed within different fields of knowledge in textbooks for social studies in upper secondary school. Three aspects of trust was analyzed; social capital and trust in one’s surroundings; trust in the political system and its institutions; how the economic system influence people’s trust. The concept of trust was examined through a thematic analysis, with discourse analytical elements that calculated frequencies of latent and semantic value words. The analysis indicate that both textbooks contain a frequent space for discourses of trust, where social trust is highlighted. Furthermore the results showed a big difference between latent reasoning about trust and direct semantic reasoning about trust. When examining study questions and tasks similar results were found, where Arena 123 had the most latent codes in the answer options, while Perspektiv på samhället had the most direct trust frequencies.

Studien behandlar missuppfattningar gällande tre begreppen platsvärde, tallinje och storleksordning inom ämnesområdet tal i decimalform. Syftet för studien är att genom en läromedelsanalys undersöka vilka aspekter av missuppfattningar som motverkas i fyra olika läromedel för den svenska årskursen 5. Ett konceptuellt ramverk används i studien där begrepp sammanlänkas för att förstå ett fenomen, som i denna studie avser missuppfattningar. Metoden som har använts är läromedelsanalys där det genomförts både kvantitativa och kvalitativa analyser av läromedel. De läromedel som har analyserats i studien är: Mitt i Prick Matematik 5A, Koll på Matematik 5A, Matte Direkt-Borgen 5B och Pixel Matematik 5A. Resultatet visar en variation av erbjudanden där samtliga läromedel motverkar missuppfattningar gällande tal i decimalform i olika utsträckning. En slutsats utifrån studien är att läromedel kan vara en möjlig resurs för arbete med tal i decimalform men förutsätter ämnesdidaktiskt medvetna lärare i undervisningen. / The study deals with misconceptions connected to the three concepts place value, order of magnitude and number line in the mathematical field of decimal numbers. The purpose of the study is to investigate, through a learning material analysis, which aspects of misconceptions that are counteracted. The learning material analysis is based on four different learning materials for the Swedish grade 5. A conceptual framework is used in the study where concepts are linked together to understand a phenomenon, in this study misconceptions. The method that has been used is learning material analysis where both quantitative and qualitative analysis of learning materials have been done. The learning materials that have been analysed are: Mitt i Prick Matematik 5A, Koll på Matematik 5A, Matte Direkt-Borgen 5B and Pixel Matematik 5A. The result shows that all teaching materials contributes to counteractions of misconceptions in different ways. A conclusion based on the study shows that teaching materials are a possible resource for the education of decimal numbers in combination with didactical knowledge.
