Theoretical frameworks for the learning of geometrical reasoning
No full textWith the growth in interest in geometrical ideas it is important to be clear about the nature of geometrical reasoning and how it develops. This paper provides an overview of three theoretical frameworks for the learning of geometrical reasoning: the van Hiele model of thinking in geometry, Fischbein’s theory of figural concepts, and Duval’s cognitive model of geometrical reasoning. Each of these frameworks provides theoretical resources to support research into the development of geometrical reasoning in students and related aspects of visualisation and construction. This overview concludes that much research about the deep process of the development and the learning of visualisation and reasoning is still needed

1185 Paediatric quality of life in congenital CMV: current knowledge and future directions
No full textBackground: congenital cytomegalovirus (cCMV) is the most common congenital infection. Around 25% of infants with cCMV develop permanent sequelae. However, there is a paucity of research evaluating the quality of life of children with cCMV.Objectives: this study evaluates current evidence regarding long-term effects of cCMV on affected children, and considers methodology used in quality of life studies that could be applied to cCMV and possible impacts on updated health economic evaluations of cCMV.Methods: we reviewed studies that reported long-term effects of cCMV on affected children, studies that measured quality of life in children with cCMV and similar paediatric populations, and studies that reported psychometric properties of quality of life measures.Results: the high prevalence of long-term sequelae amongst children with cCMV is likely to significantly impact quality of life of affected children and their families. Only one existing study assessed quality of life in children with cCMV and their parents, which was subject to bias and only incorporated one quality of life measure. We identified multiple quality of life measures that could be suitable for use in future studies of quality of life in cCMV, with varying psychometric properties and assessing different constructs.Conclusions: further research evaluating quality of life in cCMV is needed. To assess quality of life in cCMV, quality of life measures should be selected based on their relevance to sequelae of cCMV (for example, inclusion of a hearing-specific measure to assess the effect of sensorineural hearing loss), but generic quality of life measures are also important for comparison to the general population. Researchers should consider the importance of spillover effects on quality of life of family members as well as effects on the child’s own quality of life. A national multi-informant cross-sectional questionnaire-based study in the UK is being undertaken, aiming to describe quality of life of children with cCMV and their families. Quality of life data could be used to inform health economic analyses and decision-making regarding cost-effectiveness of interventions for cCMV prevention and treatment
Thinking in 3D with dynamic visualisation software
No full textThinking in 3D involves not only mental images related to external representations, but also various visualisation processes and abilities. In this workshop we explore the ways in which thinking in 3D might be supported through using 3D software applications such as Cabri 3D and small software applications developed in the DALEST project
The shaping of student knowledge: learning with dynamic geometry software
No full textThe focus of this paper is a software genre usually referred to as ‘dynamic geometry’ because of the ability of the user to dynamically manipulate geometrical figures created with the software tool. Using data from a longitudinal study of 12-13 students’ use of dynamic geometry software, the focus of the analysis is on the interpretations the students make of geometrical objects and relationships when using this form of software. The analysis suggests that the students’ mathematical reasoning is shaped by their interactions with the software in that their ability to explain geometrical facts and relationships evolves from imprecise, ‘everyday’ expressions, through reasoning that is overtly mediated by the software environment, to mathematical explanations of the geometric situation that transcend the particular tool being used. Such findings suggest that curriculum initiatives that encourage the use of dynamic geometry software are appropriate but that the incorporation of such software into classroom practices is unlikely to be straightforward

Improving uptake of vaccines in pregnancy: A service evaluation of an antenatal vaccination clinic at a tertiary hospital in the UK
No full textBackground: Vaccination against pertussis and seasonal influenza is recommended for all pregnant women in the UK. More recently COVID-19 vaccination has also been offered to women in pregnancy.Objectives: To evaluate the uptake of vaccines in pregnant women within a midwife-led immunisation clinic and to assess factors influencing pregnant women's decisions about accepting vaccination.Methods: Uptake of vaccines amongst pregnant women referred to a single UK centre for antenatal care between 01/01/19 and 02/10/19 was assessed. Interviews with 20 pregnant women explored views of antenatal vaccination and experiences of the vaccination service.Findings: Amongst 4420 women, uptake was 90.6% for pertussis and 78.8% for influenza vaccines.Factors influencing vaccine-related decision-making amongst 20 interviewed women were: healthcare professional recommendation, perceived susceptibility and risk of infection, and previous experience of vaccination and vaccine-preventable disease.Conclusions and Implications for Practice: Uptake of pertussis and influenza vaccines within a secondary care immunisation service was higher than the national or regional average. The model of vaccine delivery was associated with high levels of satisfaction. This model of vaccine delivery could be implemented elsewhere to increase vaccine uptake, and should be considered for delivery of COVID-19 vaccines in the future
The mediation of mathematical learning through the use of pedagogical tools: a sociocultural analysis
No full textA sociocultural analysis suggests that pedagogical artifacts employed in the teaching and learning of mathematics both enable and constrain learning. This paper summarises three classroom studies of mathematics learning that have utilised a sociocultural approach. Each of the studies indicates how insight can be gained into the ways in which students attempt to make sense of the mathematics they encounter
David Martyn Lloyd-Jones 1899-1981 and twentieth-century evangelicalism.
No full textThe purpose of this thesis was to demonstrate the significance of the life and ministry of David Martyn Lloyd-Jones in post-war British evangelicalism and to show that, so far as Protestant churches in England and Wales were concerned, no history of the period can afford to ignore him. It is our contention that despite differences of opinion and self- marginalization Lloyd-Jones was and has remained a major force in evangelical thinking. In order to understand how this developed the thesis has been structured along thematic lines highlighting events, persons and questions. The study begins by setting the stage with a biographical chapter and goes on to examine the kind of impact that Lloyd-Jones's preaching had on Christians of all denominations. He believed preaching to be the greatest need of the day and the position of this thesis is that preaching was Lloyd-Jones's greatest contribution to twentieth- century Christianity. As a preacher he attracted one of London's largest congregations and in chapter three we look at the history and nature of Westminster Chapel comparing it with neighbouring ministries, and establishing the kind of people who went to hear him. Chapters four and five ascertain the factors which shaped Lloyd-Jones's views on the church and show how his Reformed evangelicalism led in a separatist as opposed to an ecumenical direction and finally, to a position which was neither Congregational nor Presbyterian. Our further argument is that while he favoured unity among believers his separatist ecclesiology only exacerbated the situation and left evangelicals more divided than before. Chapters six to eight evaluate Lloyd-Jones's background, the nature of his leadership and the extent of his influence - factors which either shaped or were the outcome of his ministry - and looks at the issues which these questions raise
Forecasting the combined effects of climate and land use change on Mexican bats
No full textAim: Climate and land use change are among the most important threatening processes driving biodiversity loss, especially in the tropics. Although the potential impacts of each threat have been widely studied in isolation, few studies have assessed the impacts of climate and land cover change in combination. Here, we evaluate the exposure of a large mammalian clade, bats, to multiple scenarios of environmental change and dispersal to understand potential consequences for biodiversity conservation. Location: Mexico. Methods: We used ensemble species distribution models to forecast changes in environmental suitability for 130 bat species that occur in Mexico by 2050s under four dispersal assumptions and four combined climate and land use change scenarios. We identified regions with the strongest projected impacts for each scenario and assessed the overlap across scenarios. Results: The combined effects of climate and land use change will cause an average reduction in environmental suitability for 51% of the species across their range, regardless of scenario. Overall, species show a mean decrease in environmental suitability in at least 46% of their current range in all scenarios of change and dispersal. Climate scenarios had a higher impact on species environmental suitability than land use scenarios. There was a spatial overlap of 43% across the four environmental change scenarios for the regions projected to have the strongest impacts. Main conclusions: Combined effects of future environmental change may result in substantial declines in environmental suitability for Mexican bats even under optimistic scenarios. This study highlights the vulnerability of megadiverse regions and an indicator taxon to human disturbance. The consideration of combined threats can make an important difference in how we react to changes to conserve our biodiversity as they pose different challenges.</p
