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
Compositional Analysis of Adsorbed Organic Aerosol on a Microresonator Mass Sensor
No full textAerosol mass measurements are a key air pollution parameter that is regulated in most countries. Beyond mass measurements, the precise composition of the aerosol is essential in identifying sources and impacts on health and climate. The conventional method for simultaneously quantifying mass and composition is to collect aerosol onto filter or impactor samples followed by laboratory analysis. This approach requires long collection times—providing poor time resolution for mass measurements—and long sample preparation prior to analysis. The first limitation can be circumvented with microresonators, which are novel particulate mass sensors with high mass sensitivities and time resolutions. In addition, direct surface analysis techniques, like liquid extraction surface analysis mass spectrometry (LESA–MS), shorten sample preparation times. This work combines, for the first time, the high time resolution mass measurements of a microresonator with the integrated compositional analysis of LESA–MS. Laboratory-produced secondary organic aerosol were collected onto a microresonator via impaction with LESA–MS being used to analyze the chemical composition afterwards. The results were compared with classic filter extraction methods and literature with the final spectra matching the expected reaction products. The combined technique demonstrates an extension to current microresonator applications and illustrates their potential for ambient aerosol studies

North and South islands. Intertidal to 200 m. Endemic. Hosts. The principal host is Atrina zelandica. There are single records of hard-stages from Modiolus areolatus (Gould) and Chione stutchburyi. Waite (1909, p. 52) found that "almost every adult Pinna [= Atrina] taken had its crustacean commensual, Pinnotheres ", as did Stead (1971): in a sample of 87 A. zelandica taken from Whangarei Harbour on 13 May 1982, 83 (95.4%) contained a specimen of P. atrinicola. Remarks. Differences between P. novaezelandiae and Pinnotheres from Atrina zelandica were first noted by Bennett (1964, p. 76), who observed that mature females of "P. novaezelandiae" from A. zelandica were usually larger and had relatively longer legs. Wear (1965) reported zoea larvae of 2 species of Pinnotheres in Wellington Harbour plankton: one he could not distinguish from P. novaezelandiae as described by Bennett (1964, p. 78-79, fig. 92 and 93); the other, he suggested, was probably P. schauinslandi, "as this is the only other adult of the genus Pinnotheres recorded from New Zealand (Bennett, 1964)". Apart from figuring the telson of P. novaezelandiae, Wear did not describe his specimens. Jones (1977) has confirmed that they belong to different species. Using scanning electron microscopy, Jones (1975) compared first-stage zoeae of P. novaezelandiae and Pinnotheres from A. zelandica, noting small differences in the morphology of the rostrum, labrum, and mandibles which led him to suggest that the latter was a different species (Jones 1975, 1978). P. atrinicola is obviously very similar morphologically to P. novaezelandiae. The latter is more common in mytilids, especially Perna canaliculus, while with 2 exceptions P. atrinicola is known only from A. zelandica. Chione stutchburyi is the only host the 2 species have in common. This relative lack of overlap in hosts raises the possibility that the crabs I have recognised here as distinct species are in reality morphs of a single, polymorphic species in which post-planktonic morphology is determined by the identity of the host occupied. However, the morphology of both species is relatively constant, and both P. novaezelandiae and P. atrinicola show no patent morphological changes when found in bivalves other than their respective principal hosts, Perna canaliculus and Atrina zelandica. Further work, such as an electrophoretic study of allele frequencies in pea crabs from these 2 hosts, would help remove any remaining doubt about the status of P. atrinicola. The specific epithet is constructed from Atrina, genus of the type host, and -cola (L.), a suffix denoting one who inhabits.Published as part of Roderic D. M.

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
Opportunities for the development of geometrical reasoning in current textbooks in the UK and Japan
No full textDeveloping a good model of the school geometry curriculum continues to be one of the most important tasks in curricular design in mathematics. This paper reports on an initial analysis of current best-selling textbooks used in lower secondary schools in Japan and the UK (specifically England and Scotland). The analysis indicates that, following the specification of the mathematics curriculum in these countries, Japanese textbooks set out to develop students’ deductive reasoning skills through the explicit teaching of proof in geometry, whereas comparative UK textbooks tend, at this level, to concentrate on finding angles, measurement, drawing, and so on, coupled with a modicum of opportunities for conjecturing and inductive reasoning. The available research suggests that each approach has its own strengths and weaknesses. Finding ways of capitalising on the strengths and mitigating the weaknesses could prove helpful in formulating new curricular models and designing new student textbooks
Book Review: British Grand Strategy in the Age of American Hegemony
No full textAuthor: William D. James
Reviewed by Dr. Frank L. Jones, distinguished fellow, US Army War College
Dr. Frank L. Jones, a distinguished fellow of the US Army War College, provides a useful and comprehensive review of author William D. James’s first book, “an excellent study for members of the defense community who want to understand British grand strategy historically or aspire to policy-making or strategy-making positions and need a sound introduction.” Jones outlines James’s main arguments and the value of the case studies presented, including the “East of Suez” case study, a “vivid example of strategic adjustment where timing, domestic politics, other foreign policy priorities, economic power, and the concerns of allies shape decision making.”https://press.armywarcollege.edu/parameters_bookshelf/1069/thumbnail.jp
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
