    Abstract: In recent years there has been increased attention paid to the importance of assessment in Geographical Education, the chosen subject for this book. Assessment is an important tool for collecting information about student learning and for providing timely data to inform key stakeholders including students, teachers, parents and policymakers. To be effective, assessment needs to be valid, reliable and fair. Validity is about ensuring that we assess what we claim we are assessing. Reliability is about measuring performance and understanding in a consistent way. Without validity and reliability, assessment is unlikely to provide equitable opportunities for students to demonstrate what they know and can do. As geography educators it is therefore important that we identify the core concepts and skills in geography that we want students to master. We need a clear understanding of what the progression of learning looks like for each concept and skill so we can develop fit for purpose assessments that track and improve student learning. While there is a substantial literature on evidence-based assessment in secondary school contexts, research exploring best-practice assessment in geography is rare. This is a concern given the distinctive nature of geography and the important role of assessment in the learning process. This scholarly collection seeks to address this issue by connecting research in educational assessment with the domain of geography. The chapters are written by leading researchers in Geographical Education from across the globe. These chapters provide examples of innovation through the collective voices of geography teacher educator scholars from across Australia, USA, South Korea, Germany, Switzerland and Singapore. What unifies the work in this book, is that each chapter focuses on a key feature of the discipline of geography, providing scholarly examples of evidence-based practices for assessing student’s knowledge and skills. .

    Description: Ferromanganese oxide crusts are members of a family of manganese and iron oxide precipitates that are widely distributed in the lithosphere. They can be defined as encrustations forming largely on hard substrates that are at least periodically kept free from detrital sedimentation by strong currents, steep slopes, or both. In near-shore or hydrothermal environments where metal supply is much greater than it is in most of the open ocean, crusts may also form on soft sediments. The pioneering German "Midpac I" investigation of cobalt-rich ferromanganese oxide phases in the Central Pacific in 1981 lead to the development of interest in the processes causing cobalt enrichment in seamount "nodules" and crusts and the recognition of the possible resources in cobalt rich crusts within 200 miles of U.S. and territorial coasts. Crusts pose specific problems because unlike nodules they tend to occur in a highly localized manner. They also generally adhere to hard substrates in such a fashion that they cannot easily be separated from underlying substrate during recovery; And finally, their elemental composition varies from nearly pure manganese or iron oxides (both frequently hydrothermal in origin) to the fairly consistent admixtures that characterize cobalt-rich crusts. The main effort of this study has been to collect and evaluate all available samples and information, to analyze new samples by means of well-controlled and defined analytical procedures, and to present all information through the end of 1987 in a consistent and complete form. As a part of this effort, all data were classified and normalized for mapping purposes so that information from diverse sources could be compared over larger geographic areas. For resolving the difficult problem of contamination and water treatment a basic procedure was chosen that normalizes data to a constant Fe+Mn content in order to draw ocean wide conclusions on the distribution and chemical properties of ferromanganese crusts. Investigators who wish to use other means of dealing with the comparability problem have the complete basic information in the published database to create their own models.

    Description: This dataset provides first results of the ongoing search for cryptotephras in the International Continental Scientific Drilling Program (ICDP) sediment core 5017-1 retrieved from the deep northern DS basin in 2010/11. 56 samples from sediments and rock salts were collected between 89.30 and 94.09 m sediment depth below lake floor from cores 5017-1-A-43 and 5017-1-A-44, focusing on the Lateglacial time period (~15-11.4 cal. ka BP), when Lake Lisan – the precursor of the DS – shrank from its glacial high-stand to the Holocene low levels. Sampling was performed in contiguous 5 cm steps with sample volumes of 5 cm³ and excluding mass-transported deposits thicker than 5 cm. The cryptotephra glass-shard extraction protocol followed established separation procedures (Blockley et al. 2005, doi:10.1016/j.quascirev.2004.12.008), and has been further adapted to the extreme salinity and sediment recycling of the DS. Glass shards were picked using a 100 μm-diameter gas-chromatography syringe attached to a micromanipulator (Lane et al. 2014, doi:10.1016/j.jas.2013.10.033), embedded in Araldite 2020 epoxy resin and ground and polished for electron probe microanalyses (EPMA). Major-element composition of individual glass shards was measured using a JEOL JXA-8230 electron microprobe at GFZ Potsdam, Germany (15 kV, 5-10 nA, 5-10 µm beam size). Instrumental calibration used natural mineral standards and the precision and accuracy of measurements during analytical runs were monitored using the glass standards Lipari obsidian (Hunt & Hill 1996, doi:10.1016/1040-6182(95)00088-7; Kuehn et al. 2011,doi:10.1016/j.quaint.2011.08.022) and MPI-Ding glasses ATHO-G, StHs-6-80-G and GOR-132-G (Jochum et al. 2006, doi:10.1029/2005GC001060). From six glass samples at least 10 glass shards per sample were measured by EPMA and for three samples replicate measurements on different glass shards were performed. After removal of glass geochemical measurements with totals 〈90%, 102 glass shard measurements remain in total. In general, cryptotephra is abundant in the Dead Sea record (up to ~100 shards per cm³), but often glasses are physically and/or chemically altered. The glass shard measurements reveal a heterogeneous geochemical composition, with mainly rhyolitic and some trachytic glasses potentially sourced from Italian, Aegean and Anatolian volcanoes. These first results demonstrate the great potential of crypto-tephrochronology in the DS record for improving its chronology and connecting the Levantine region to the Mediterranean tephra framework.

    Description: This dataset provides the data for the four glass standards used for monitoring of the precision and accuracy of electron probe microanalyses (EPMA) during analytical runs of cryptotephra glass-shards in the International Continental Scientific Drilling Program (ICDP) sediment core 5017-1 (see first dataset). For each EPMA run, all four glass standards were measured. The major-element composition of the glass standards was measured using a JEOL JXA-8230 electron microprobe at GFZ Potsdam, Germany (15 kV, 5-10 nA, 5-10 µm beam size). Instrumental calibration used natural mineral standards. Glass standards were Lipari obsidian (Hunt & Hill 1996, doi:10.1016/1040-6182(95)00088-7; Kuehn et al. 2011, doi:10.1016/j.quaint.2011.08.022) and MPI-Ding glasses ATHO-G, StHs-6-80-G and GOR-132-G (Jochum et al. 2006, doi:10.1029/2005GC001060).
