Appropriateness of surgery performed for abdominal aortic aneurysm at tertiary hospitals in Spain
2021
Background: The aim of this study was to analyze the appropriateness of the type of repair (open or endovascular) performed for abdominal aortic aneurysm (AAA) in five university hospitals in Spain, according to evidence-based recommendations. Methods: A multicenter, retrospective cross-sectional study of patients with AAA who underwent elective open surgical repair (OSR) or endovascular aneurysm repair (EVAR). Data were collected on demographic and clinical variables and type of surgical repair. A pair of vascular surgeons from each participating hospital performed a blinded assessment based on GRADE recommendations. The concordance between the two evaluators and the agreement between thei…
Enabling Settings for Learning : Observations Related to Design Communication
2020
The paper draws on two cases of learning settings that were converted to meet up-to-date educational requirements within these learning contexts. The authors address the role of stakeholder perspectives. Focusing on the learning situation, they present an articulation tool to aid dialogue between key stakeholder perspectives in a (re)design process. Dialogue is a way to figure out relevant issues and to establish the common ground between participants. The goal of a redesign process is that user requirements are well understood, and the design is embedded into local practices, informed of constraints and aware of potential opportunities regarding educational technology. peerReviewed
Effects of school-based physical activity on mathematics performance in children: a systematic review
2019
AbstractBackgroundThe benefits of physical activity (PA) on children’s health and wellbeing are well established. However, the benefits of PA on academic performance and particularly on mathematics performance warrant systematic analysis. Mathematics is one of the core subjects in school education globally.MethodsWe systematically searched, analysed and synthesized the literature on the effects of school-based PA interventions on mathematics performance in children aged 4–16. A total of 29 studies consisting of randomised trials and other interventions with control groups were identified through a systematic search, and 11 of them provided sufficient data and appropriate design for a meta-a…
Energy Drink Consumption Among Finnish Adolescents: Prevalence, Associated Background Factors, Individual Resources, and Family Factors.
2020
Objectives: Energy drink consumption among adolescents has become a notable global phenomenon, and has been associated with numerous negative health outcomes. In order to understand the popularity of energy drinks among adolescents, and to target interventions, it is important to identify the determinants underpinning consumption. Methods: The nationally representative data (cross-sectional) were drawn from the Health Behaviour in School-aged Children (HBSC) surveys, conducted in 2014 and 2018, each comprising 13- and 15-year-old Finnish adolescents (n = 7405). Results: Weekly energy drink consumption increased among Finnish adolescents between 2014 (18.2%) and 2018 (24.4%), especially amon…
Exploring students’ identity development from the perspective of study difficulties
2020
This work-in-progress paper in research category reports preliminary findings on how students taking introductory computing courses develop identity from the perspective of study difficulties. The motivation was that students identified lack of meaning and prospects (cf. identity) as a study difficulty in a previous qualitative study. The present study further explores this finding by issuing both an identity development and a self-efficacy scale to a larger first-year student cohort. The aim is to characterize the study cohort by the aspects included in the identity development scale, and thereby increase understandings of students’ challenges. Moreover, a correlation analysis between iden…
Motivational sources of practical nursing students at risk of dropping out from vocational education and training
2019
The aim of this study was to contribute to the understanding of the reasons for low or high academic motivation among practical nursing students at risk of dropping out from vocational education and training. The research data consisted of semi-structured interviews with 14 Finnish students, which were analysed by qualitative content analysis. The analysis identified six motivational sources. Two of these sources – Responsible agency and Completing out of necessity – were related to engagement in studying, whereas two other sources – Exhaustion from learning challenges and Tight-roping between competing responsibilities – were related to disengagement from studying. Emotional drive and Soci…
Visual Literacy From the Perspective of the VTS Method
2017
The purpose of this article is to investigate visual literacy from the perspective of the VTS (Visual Thinking Strategies) method. The authors examine the viewpoints of seven American elementary school teachers on visual literacy and its meanings in the context of the VTS method. Data collection was done using a semi-structured questionnaire, which was followed by theory-driven content analysis. The authors emphasize that when supporting holistic development in a teaching context, it is the interconnected nature of aesthetics, growth and the learner’s learning which is more important than developing special skills, like visual literacy. In the teaching context visual literacy and language d…
Higher education teachers’ descriptions of their own learning: a quantitative perspective
2017
In this large-scale study, higher education teachers’ (n = 1028) descriptions of their own learning are examined with quantitative analyses. The study follows up an earlier qualitative study that, using a phenomenographic approach, identified four different ways in which teachers at Finnish universities of applied sciences described their own learning. The purpose of the present study was to find out how teachers’ descriptions were divided into the categories formed in the previous study and to examine whether teachers’ descriptions of their learning differ according to their position, gender and age. The results show that most teachers described their learning as an individual activity. Di…
Visual cues improve students’ understanding of divergence and curl: Evidence from eye movements during reading and problem solving
2019
The coordination of multiple external representations is important for learning, but yet a difficult task for students, requiring instructional support. The subject in this study covers a typical relation in physics between abstract mathematical equations (definitions of divergence and curl) and a visual representation (vector field plot). To support the connection across both representations, two instructions with written explanations, equations, and visual representations (differing only in the presence of visual cues) were designed and their impact on students’ performance was tested. We captured students’ eye movements while they processed the written instruction and solved subsequent c…
Pair interactions in online assessments of collaborative problem solving: case-based portraits
2018
This exploratory case study focuses on how pairs of students can build a shared understanding and acquire collaborative problem-solving (CPS) practices during an online assessment of CPS skills, which is seen in the context of the CPS construct, in a symmetrical and asymmetrical task type. Even though CPS is widely recognised as a core twenty-first-century competency, its nature is not yet well understood. Also, until recently, most of studies have focused on the individual’s solution to a problem or on the skills individuals bring into a problem-solving space. This study extends from an individual- to group-level focus in CPS, emphasising the role and quality of the social aspects in CPS p…
