Abstract [sv]

Världens blickar har under de två senaste decennierna riktas mot östra Asien när lärande och undervisning i matematik står i centrum för diskussioner. En anledning till det ökade intresset är troligtvis att dessa regioner, gång efter annan, placerar sig i topp i olika internationella mätningar som TIMMS och Pisa medan Sverige och många andra OECD-länder hamnar på en mer blygsam placering. Det finns flera tänkbara förklaringar till sådana skillnader. En avgörande faktor för undervisningskvalitet och som ofta lyfts fram är den kinesiska undervisningstraditionen Bianshi Jiaoxue—undervisa utifrån variation av ämnesinnehållet. Denna tradition erbjuder flera intressanta begrepp som kan användas som verktyg för att planera och genomföra undervisning, speciellt med avseende på hur uppgifter kan sammanlänkas för att skapa effektivt och fördjupat lärande i matematik. Vi illustrerar några centrala begrepp inom traditionen genom att lyfta några exempel från en lektion om addition och subtraktion med tal i bråkform genomförd i Shanghai samt från en intervju genomförd med den undervisande läraren. Lektions- och intervjudata kommer från ett av samarbetsprojekt, finansierat av Vetenskapsrådet, mellan forskare från Jönköping University och Hong Kong University. Utgångspunkten relaterat konferensens tema är att en praktisk teori är en viktig komponent för undervisning på vetenskaplig grund.

Abstract [en]

Understanding the object of learning is a significant, yet often elusive, part of analysing a lesson through the lens of variation theory of learning. It involves not only specifying the usual learning objectives in terms of content and how to handle it, but also through identification of critical aspects to be discerned. The role of critical aspects in formulating the object of learning in an elaborate and useful way is the focus of this discussion paper. This is explored by comparing two mathematics lessons in China, designed and conducted by two teachers skilfully with bianshi pedagogy. As the content, textbook resources and students’ characteristics are basically the same, the subtle difference in the observed objects of learning becomes apparent. This difference is reflected in two contrasting sets of critical aspects that are structuring the lessons. In Marton (2015), “the object of learning is described primarily in terms of critical aspects and features to be discerned” for a better precision. Our analysis may contribute to a further discussion about how far the critical aspects constitute the meanings behind the content, which is not commonly addressed when a lesson is mainly analysed in terms of patterns of variation in a mechanical manner.

Abstract [en]

Previous research indicates that manipulatives, like base-ten blocks, not necessarily strengthen students’ understanding of numerical place-value and the decimal numeral system. This study takes its starting point in the hypothesis that to create functional teaching situations with base-ten blocks, it is necessary to first know students’ prior understanding of such manipulatives. Therefore, here we present a phenomenographic analysis of students’ understanding how such manipulative material can be used to represent multidigit numbers. The data was collected from individual interviews with 58 students in grade 1 (6-7 years old).We identify six qualitatively different categories of students’ understanding, and, based on these, suggest implications for the design of teaching situations.

Abstract [en]

When a number sentence includes more than one operation, students are taught to follow the rules for the order of operations to get the correct result. In this context, brackets are used to determine the operations that should be calculated first. However, it seems that the written format of an arithmetical expression has an impact on the way students evaluate this expression. It also seems that a connection exists between this way of evaluation and an understanding of structure. Both issues are examined in this paper. A number of arithmetical expressions in a rational form were given to primary school students from Greece and Sweden. The collected findings strengthen our hypothesis that this rational form of the arithmetical expressions was of critical importance for the students’ decision on how to evaluate these expressions. They temporarily put aside their knowledge about the rules for the order of operations. Instead, the way they evaluated the expressions indicates an implicit use of what we call in this paper “mental” brackets. It is very likely that the use of these “mental” brackets is closely connected with students’ structure sense.

Abstract [en]

Learning study is an adapted version of lesson study developed in Hong Kong and Sweden. It has commonalities with lesson study but is framed within a specific pedagogical learning theory – variation theory. Central in variation theory is the object of learning and what is critical for students’ learning. Hence, as with lesson study, it is a collective and iterative work where teachers explore how they can make the object of learning available to students, but what characterises learning study is the use of a specific learning theory. In this process, special attention is paid to the critical aspects of the object of learning. We argue that to identify the aspects that are critical, the aspects need to be verified and refined in classrooms. In this chapter, we demonstrate how teachers gain knowledge about such critical aspects. Particularly, we show how these critical aspects cannot be extracted only from the mathematical content or the students pre-understanding alone, but evolve during the learning study cycles. For this we use a learning study about the mathematical topic of rate of change in grade 9 in Sweden as an illustration. We describe how an analysis of how students solved tasks in pre- and post-test and during the lessons, as well as how the mathematical content was presented in lessons, helped the teachers identify what was critical for learning to understand and express the rate of change for a dynamic situation.

Abstract [sv]

Syftet med denna studie är att jämföra olika frågeställningars betydelse för hur elever relaterar och uttrycker relationer mellan olika storheter i uppgifter om förändringstakt i matematik. Genom en kvalitativ analys jämför vi hur elever i årskurs 9 besvarar två olika typer av uppgifter om hur snabbt vätskevolymen i två medicinska droppåsar förändras. Analysen pekar bland annat på att en jämförande uppgift (”vilken förändras snabbast?”) kan öppna ett brett utfallsrum, där vi kunde observera fem kvalitativt skilda sätt att lösa uppgiften. Vidare verkar en uppgift som efterfrågar ett värde (”hur snabbt förändras den?”) kunna leda eleverna mot multiplikativa jämförelser, som ligger nära den vedertagna matematiska innebörden i begreppet förändringstakt. Avslutningsvis diskuterar vi de olika frågeställningarnas potential för att lyfta olika aspekter av begreppet förändringstakt och hur de skulle kunna användas av lärare för olika syften i undervisningen.

Abstract [en]

The aim of this study is to compare the impact of different phrasings of questions as of how students relate and express relations between different quantities in student tasks concerning rate of change. Through a qualitative analysis we compare how students in ninth grade (age 15) respond to two different framings of questions, concerning how fast the volume of fluid in two medicine bags change. The analysis indicates that a comparing question (”which changes fastest?”) can open up a wide outcome space, in which we could observe five qualitatively distinct ways of solving the task. Furthermore, a question that requests a value (“how fast does it change?”) seem to encourage students to make multiplicative comparisons, which is close to the mathematical meaning of rate of change. Finally, we discuss the potential of each question for pointing to different aspects of rate of change, and how they could be used by teachers for different purposes in teaching situations.

Abstract [en]

How do secondary school science teachers justify the model of a particulate nature of matter, and how do the arguments they use relate to historical arguments? To find out, we individually interviewed 11 in-service secondary school science teachers (certified to teach chemistry and/or physics in secondary school, and with 2–30 years of teaching experience) regarding their arguments for the particulate nature of matter and experiments that could demonstrate the existence of particles. The collected data were qualitatively analyzed. Three qualitatively different categories of arguments could be constructed from data: philosophical argumentsindirect experimental arguments, and direct experimental arguments. The indirect experimental arguments, which is the largest category, could be further divided into qualitatively different subcategories: non-specific research and experiments, and chemical, physical and subatomic experiments. Even though several experiments and arguments were suggested by the informants in our study, the arguments regarding the validity of the experiments were quite uncertain and vague. The experiments and arguments were used to corroborate the particulate nature of matter and taken for granted in advance rather than used to justify a model with particles. The outcome was discussed in relation to scientific arguments and experiments and in view of results from previous science education research. Based on our data, teacher education and in-service teacher training, as well as teacher guides, were suggested to be more elaborate regarding contemporary knowledge, with direct experimental evidence for the particulate nature of matter being presented.
