Schultheiss, Joshua. „Att representera tal i decimalform : En kvalitativ intervjustudie om hur lärare undervisar för att elever ska skapa förståelse för tal i decimalform genom olika representationsformer“.

Der volle Inhalt der QuelleThe curriculum for mathematics describes that pupils should be given conditions to interpret everyday and mathematical situations by using mathematical different forms of expression. The concept of forms of expression can be equated with representation. The aim of this study is to find out how teachers use representations to give pupils the opportunity to create an understanding of decimal numbers. This study is using qualitative interviews that are focusing on teachers’ description of their teaching of decimal numbers. The collection of data was conducted through semi-structured interviews with eight teachers. As a starting point in this study, a theoretical framework has been used in order to analyze the collected empirical data tough a processed thematic analysis. The analysis shows that teachers use different kinds of representations in their teaching. The results show what teachers consider as relevant for pupils to know to create an understanding to enhance their knowledges of decimal numbers and how teachers choose to teach in the area. The most common representation the teachers chose to include in their teaching was the number line, but base-ten materials and other laboratory materials are also used.

Der volle Inhalt der QuelleIn grades 4–6, students must undergo a progression to learn how rational numbers and numbers in decimal form are structured. Research has shown that there can be several difficulties and misconceptions about the area, including knowing the different place value of numbers. This study has been inspired by a previous study, conducted by Jarl and Johansson (2014). The aim of this study is to compare whether the same critical aspects identified in Jarl and Johansson (2014) studies also show up in other student groups. The subject of interest in this study was: What critical aspects can be identified in a grade 4 and a grade 5 around numbers in decimal form? In order to be able to answer the question, the students in this study have had to complete a worksheet with tasks linked to numbers in decimal form. Thereafter, qualitative interviews were conducted to gain a broader insight into what critical aspects the students have or have not distinguished. The choice of method in the study has elements of the theory of variation where the students need to see the necessary details (in the study called critical aspects). The results of the study show that all critical aspects that were identified in Jarl and Johansson's (2014) study were also critical in this study. However, a new critical aspect was identified: Students need to understand that numbers on each side of the decimal point together must become a number. Knowledge of critical aspects can be seen as special knowledge for teachers to know what can be misunderstood about the mathematical field. This knowledge cannot generalize, but it can be transferable so that a critical aspect can be identified in other student groups.
Sandin, Sara. „Elevers olika uppfattningar av tal i decimalform i en svensk kontext. : - En studie som bygger på kategorisering av elevers uppfattningar framtagen av tidigare forskning inom det matematikdidaktiska forskningsfältet“.

Der volle Inhalt der QuelleIn this study earlier international research has been used from a Swedish perspective to investigate the field of decimal numbers. A theoretical framework for students’ various perceptions of decimal number has developed from the mathematical didactic research field. Earlier studies have done different attempts to categories students’ various perceptions of decimal numbers (Moloney & Stacey, 1997; Resnik et al., 1989; Sackur-Grisvard & Léonard, 1985; Stacey & Steinle, 1998). Sackur-Grisvard and Léonard (1985) categorization focus on students’ earlier knowledge in the mathematical field. Their theoretical framework involves the use of three different rules; the whole number rule, the fraction rule and the zero rule. Sackur-Grisvard and Léonard’s (1985) theoretical framework has not been used much in the Swedish research field. In this study the framework has been used to investigate if it can be used as a tool to categorise students in grade 4 and grade 5 various perception of decimal numbers. In this study the method triangulation has been used which involves a written test and semi-structure interviews. In the written test all students got tasks where they would compare and order different decimal numbers. The students result from the test were used to choose a few students from grade 4 and grade 5 to do the semi-structured interviews through a target-driven selection. The result showed that the theoretical framework did have some limits and several students´ did not belong to only one category, several students did use more than one of the three rules in the written test. The students result showed a progression where students from grade 6 performed best on the test followed by students from grade 5, students in grade 4 performed worst.

Der volle Inhalt der QuelleThe aim of the study is to obtain a deeper understanding of students' knowledge of the decimal number system. The subject of interest is what different approaches can be identified when students describe how they have solved operations that deal with the decimal number system? This study has used a qualitative content analysis, where the students' different approaches to solving tasks have been analyzed. The study has borrowed words such as understanding and qualitative differences from the phenomenographic research approach. In the study, 17 students participated and completed a worksheet. Subsequently, 10 students were randomly selected for further interviews. The presented results are based on the data where there are differences in student responses. Through the task and the subsequent student interviews different approaches were identified. The main result is that the students solved the tasks with different approaches. In the discussion section, the student responses have been compared with previous research. Furthermore, the relevance of the result for the professional role and how the mathematics teacher is also problematized can use the results to plan and carry out their teaching.
