Developing pre-service teachers’ noticing of students’ understanding of the derivative concept

This research study examines the development of the ability of pre-service teachers to notice signs of students’ understanding of the derivative concept. It analyses preservice teachers’ interpretations of written solutions to problems involving the derivative concept before and after participating in a teacher training module. The results indicate that the development of this skill is linked to pre-service teachers’ progressive understanding of the mathematical elements that students use to solve problems. We have used these results to make some suggestions for teacher training programmes.

50 years of the ‘twin engine’. Franco-German reconciliation, European integration and reflections for Asia. EU Centre Singapore Background Brief No. 8, March 2013

On 22 January 2013, French President François Hollande and German Chancellor Angela Merkel gathered in Berlin to celebrate the 50th anniversary of the signing of the Élysée Treaty, the document that ended centuries of rivalry and warfare between their two countries. It is all too easy to forget the importance of Franco-German reconciliation. The 1950 Schuman Declaration, which led to the creation of the European Union’s (EU) predecessor, the European Coal and Steel Community (ECSC), sought to render the prospect of war between France and Germany ‘not only unthinkable but materially impossible’. Over 60 years later, when the EU was awarded the Nobel Peace Prize, the Norwegian Nobel Committee noted that indeed, ‘war between Germany and France is unthinkable’. Halfway around the world in Asia, the other theatre of World War II, tensions between China and Japan have arisen, with Taiwan and South Korea also in the fray. Nationalist movements in these countries have grown. This background brief lays out the issues for a timely reappraisal of the applicability, or otherwise, of the European integration and reconciliation processes to East Asia. The brief seeks to outline the contours of the historic act of Franco-German reconciliation, and its consequences ever since. Starting from a brief look at the history of rivalry and war between the two countries, the brief examines the events leading to the signing of the Élysée Treaty in 1963, and the development of Franco-German exchanges that have cemented the relationship. Difficulties between the countries are also raised. A timescale analysis of the opinion of the two publics is considered, as a measure of the success of Franco-German reconciliation.

Taiwanese Lobbying in the European Union: ‘Workable Diplomacy’ and its Limitations. EU Diplomacy Paper 8/2015

The policy of the European Union (EU) towards Taiwan has mostly been analysed either as a by-product of EU-China relations or with reference to the general lack of a European geopolitical approach towards East Asia. By adopting a lobbying approach which focusses on Taiwan’s different ‘channels of influence’ within the complex European foreign policy system in Brussels, this study provides new insights into the functioning of EU-Taiwan relations. It also sheds new light on the implications of the radical change in Taiwanese diplomacy after 2008, when Chen Shui-bian’s assertive and identity-based diplomacy was replaced with the Kuomintang’s new dogma of ‘workable diplomacy’. Based on semi-guided interviews with Taiwanese and European actors, this paper examines why Taiwanese lobbying in Brussels, albeit very active and professional, is not salient enough to meet the challenges arising from the overwhelming Chinese competition and from the increasing proliferation of regional trade agreements – with active EU participation – in the Asia-Pacific region. It argues that the pragmatic ‘workable diplomacy’ approach, while smoothing out working-level relations between Taiwan and the EU, fails to attract a sufficient degree of political and public attention in Europe to the Taiwan question and thus fosters the neglect of Taiwan by European foreign policy-makers. The main challenge faced by Taiwanese diplomacy, however, is not simply one of convincing through technical arguments, but one of agenda setting, that is, of redefining European priorities in Taiwan’s favour.

Sedimentology and geochemistry of ODP Site 184-1144

We analyzed sediment from Ocean Drilling Program (ODP) Site 1144 in the northern South China Sea to examine the weathering response of SE Asia to the strengthening of the East Asian Monsoon (EAM) since 14 ka. Our high-resolution record highlights the decoupling between continental chemical weathering, physical erosion and summer monsoon intensity. Mass accumulation rates, Ti/Ca, K/Rb, hematite/goethite and 87Sr/86Sr show sharp excursions from 11 to 8 ka, peaking at 10 ka. Clay minerals show a shorter-lived response with a higher kaolinite/(illite + chlorite) ratio at 10.7-9.5 ka. However, not all proxies show a clear response to environmental changes. Magnetic susceptibility rises sharply between 12 and 11 ka. Grain-size becomes finer from 14 to 10 ka and then coarsens until ~7 ka, but is probably controlled by bottom current flow and sealevel. Sr and Nd isotopes show that material is dominantly eroded from Taiwan with a lesser flux from Luzon, while clay mineralogy suggests that the primary sources during the Early Holocene were reworked via the shelf in the Taiwan Strait, rather than directly from Taiwan. Erosion was enhanced during monsoon strengthening and caused reworking of chemically weathered Pleistocene sediment largely from the now flooded Taiwan Strait, which was transgressed by ~8 ka, cutting off supply to the deep-water slope. None of the proxies shows an erosional response lasting until ~6 ka, when speleothem oxygen isotope records indicate the start of monsoon weakening. Although more weathered sediments were deposited from 11 to 8 ka when the monsoon was strong these are reworked and represent more weathering during the last glacial maximum (LGM) when the summer monsoon was weaker but the shelves were exposed.

Age model of ODP Site 184-1146 (Table 1)

Clay mineral assemblages at ODP Site 1146 in the northern South China Sea are used to investigate sediment source and transport processes and to evaluate the evolution of the East Asian monsoon over the past 2 Myr. Clay minerals consist mainly of illite (22-43%) and smectite (12-48%), with associated chlorite (10-30%), kaolinite (2-18%), and random mixed-layer clays (5-22%). Hydrodynamic and mineralogical studies indicate that illite and chlorite sources include Taiwan and the Yangtze River, that smectite and mixed-layer clays originate predominantly from Luzon and Indonesia, and that kaolinite is primarily derived from the Pearl River. Mineral assemblages indicate strong glacial-interglacial cyclicity, with high illite, chlorite, and kaolinite content during glacials and high smectite and mixed-layer clay content during interglacials. During interglacials, summer enhanced monsoon (southwesterly) currents transport more smectite and mixed-layer clays to Site 1146 whereas during glacials, enhanced winter monsoon (northerly) currents transport more illite and chlorite from Taiwan and the Yangtze River. The ratio (smectite+mixed layers)/(illite+chlorite) was adopted as a proxy for East Asian monsoon variability. Higher ratios indicate strengthened summer-monsoon winds and weakened winter-monsoon winds during interglacials. In contrast, lower ratios indicate a strongly intensified winter monsoon and weakened summer monsoon during glacials. Spectral analysis indicates the mineral ratio was dominantly forced by monsoon variability prior to the development of large-scale glaciation at 1.2 Myr and by both monsoon variability and the effects of changing sea level in the interval 1.2 Myr to present.
