The point of departure in this study is the question: do teachers who develop theoretical knowledge of the variation theory change the way(s) they offer their pupils the object of learning due to the theoretical framework. The aim of the study is to describe this development, i. e. to find if and how teachers developed theoretical knowledge when planning instruction, and in what way(s) this has an

The aim of this article is to analyse the aspects that teachers intend to focus on in teaching mathematics and the students' needs, i.e. what is critical for student learning. The article develops an argument for the importance of identifying the "critical aspects" as a basis for the teachers to promote student learning of Mathematics from preschool to upper secondary school. The article concludes

The aim of this study is to describe in what ways the object of learning changes shape during its way from the intended (planned), enacted (offered) and lived (discerned) object of learning. The study is based on variation theory, and learning study is used as a model. A total of three preschool teachers, 39 children aged 4-5 years and three researchers participated in the study. Three interventio

Preschool children's learning isthe subject of this study. Three children aged 4, 5 and 6 participated. The data consist of individual interviews with the children before and after the intervention and a videotaped intervention. Our results show that children seem to see a whole as something that is not cut into pieces, no matter what it looks like. They do not necessarily refer to the whole when

In this article a learning study is presented, and the object of learning is sedimentary rocks' formation and decomposition, a part of the rock-cycle. The study included 5 lessons in 5 different groups of 5th grade pupils. 85 students and 7 teachers participated in the study. The lessons were 40 minutes each and the teacher and location of all classes remained constant. 4 lessons were planned base

Although students' understanding of the concept of function has been studied by quite a number of researchers internationally, there has not been a lot of research on the subject in Sweden. This paper is an attempt to analyse what the students are offered to learn about the concept of function both in the classroom and in textbooks and what the students actually learn. The presentation is based on

The aim of this study is to describe in what ways variation can be used in learning situations for pupils with autism to evoke deep understanding of activities in natural settings. The combination of variation and structure was designed to make each pupil discern new aspects of their learning objects. The analysis of the six participants’ learning was based on the variation theory, and focused on

In this article an educational action research study, based on a phenomenographic approach, is reported in which unexpected results have been possible to gather thanks to the inductive design of the study. The aim is to describe the ways in which contrasts of critical aspects of a learning object affect the students' generative learning found by analysing three learning studies based on the theory

Background: The failing heart is traditionally described as metabolically inflexible and oxygen starved, causing energetic deficit and contractile dysfunction. Current metabolic modulator therapies aim to increase glucose oxidation to increase oxygen efficiency of adenosine triphosphate production, with mixed results. Methods: To investigate metabolic flexibility and oxygen delivery in the failing

Although tyrosine kinase inhibitors (TKIs) are effective in treating chronic myeloid leukemia (CML), they often fail to eradicate the leukemia-initiating stem cells (LSCs), causing disease persistence and relapse. Evidence indicates that LSC persistence may be because of bone marrow (BM) niche protection; however, little is known about the underlying mechanisms. Herein, we molecularly and function

The hippocampus is one of the most studied neuroanatomical structures due to its involvement in attention, learning, and memory as well as its atrophy in ageing, neurological, and psychiatric diseases. Hippocampal shape changes, however, are complex and cannot be fully characterized by a single summary metric such as hippocampal volume as determined from MR images. In this work, we propose an auto

The purpose of this thesis is to understand how consumer innovativeness and motivations relate to the decision to adopt green innovations. This thesis examines two forms of green transport innovations, shared e-bikes and e-scooters, which are part of the shared micromobility phenomenon. The penetration of shared micromobility into the market is estimated to increase in the upcoming years, and incr

Importance: It is important to determine the added clinical value for tau positron emission tomography (PET) in the diagnostic workup of patients with cognitive symptoms before widespread implementation in clinical practice. Objective: To prospectively study the added clinical value of PET detecting tau pathology in Alzheimer disease (AD). Design, Setting, and Participants: This prospective cohort

The genomic conflict between the sexes is caused by differences in the optimal male and female reproductive strategies, and is a major contributor to genetic, phenotypic, and life history variation. While early experimental work appeared to strongly support predictions from sexual conflict, recent work has produced more ambiguous results. Recent advances in experimental evolution studies combined

Agricultural expansion and intensification have boosted global food production but have come at the cost of environmental degradation and biodiversity loss. Biodiversity-friendly farming that boosts ecosystem services, such as pollination and natural pest control, is widely being advocated to maintain and improve agricultural productivity while safeguarding biodiversity. A vast body of evidence sh
