title: Developing a digital assessment in senior secondary physical education

authors: Penney, Dawn

subjects: physical education

abstract: Background: The Digital Forms of Assessment project is a three-year Australian Research Council Linkage research project being conducted by Edith Cowan University's Centre for Schooling and Learning Technologies (CSaLT) in partnership with the Curriculum Council of Western Australia. The project is investigating the potential for a digital format external examination to rigorously interrogate student learning as demonstrated in and through practical tasks.
Aims: The project has been designed to inform the ongoing development of Physical Education Studies assessment in Western Australia and contribute to national and international developments in assessment in physical education and other areas of education that incorporate a practical and/or performance dimension. It aims to investigate authentic digital forms of assessment with high levels of reliability that are capable of being scaled-up for state-wide implementation in a cost effective manner. It seeks to provide research based insights for physical education teachers concerned to design authentic assessment tasks that maximise opportunities for students' varied knowledge, skills and understandings to be demonstrated.
Method: The project has utilised multiple methods of data collection to gather data relating to the development and implementation of assessment tasks utilising digital technologies, student participation in the assessment tasks, the experience and outcomes arising from marking procedures also utilising digital technologies, and teacher and student responses to the new forms of assessment. It has involved video-recording and computer-based digital capture of student work, participant observation, digital capture of computer-based marking outputs, and interviews with teachers and students. This paper focuses on data from the first two years of the project, relating to the design, implementation and experience of undertaking digital forms of assessment. Discussion draws on data from five teachers and a total of seventy-two students in four schools participating in the first two years of the project, with assessment tasks addressing a range of physical activity contexts.
Results: An assessment task comprising integrated computer-based and practically based components was designed, adapted for varied physical activity settings and successfully implemented in project schools. Students have perceived the assessment task to be authentic and meaningful for the Physical Education Studies course and have liked the way in which ‘practical’ and ‘theoretical’ aspects are combined in the task. Teachers have identified the task as aligning well with the pedagogic intent of the course and as providing a valid means of assessment of students' skills, knowledge and understandings relating to the aspects of course content that it was designed to address. Evaluation of the task implementation has utilised a feasibility framework, addressing technical, pedagogic, manageability, and functional feasibility. Results to date are encouraging in relation to each dimension. Refinements have been made to further enhance the task and implementation processes in the final year of the project.
Conclusion: The study has demonstrated the pedagogic feasibility of digital assessment aligning with the pedagogical intentions of the new course in Western Australia. Issues are discussed in relation to the prospective wider implementation of the technologies employed.

title: Is fish food from aquarium suppliers a vector for non-native zooplankton to New Zealand?

authors: Mahaarachchige, Buddhika Udayangani Perera

subjects: Artemia

abstract: There have been a number of recent records of non-native zooplankton invasions in New Zealand, but the transport vectors leading to their introduction are not well understood.  Commercially available fish foods containing zooplankton are widely used in home aquariums and the aquaculture industry. These foods are either imported to, or cultured within, New Zealand, and sold as freeze-dried, sun-dried or frozen adults, as capsulated or decapsulated cysts, or as live individuals. In this study, fish food containing Daphnia O.F. Müller, 1785  (Cladocera), Artemia (brine shrimp) and Brachionus (rotifers) were bought from a variety of commercial suppliers within the North Island, New Zealand, which were cultured and manufactured domestically or internationally. Live Daphnia samples were identified morphologically and were found to contain a variety of both native and non-native Daphnia species, as well as copepods, ostracods, rotifers and other non-Daphnia cladoceran species. Freeze-dried and sun-dried diapausing eggs of Daphnia and the rotifer Brachionus were incubated in artificial pond water, Aachener Daphnien Medium (ADaM) and filtered pond water, but hatching of these were unsuccessful. In contrast, Artemia bought as both capsulated and decapsulated cysts were successfully hatched in water with a salinity of 25 ppt and temperatures of 20 °C. The resulting Artemia populations were either parthenogenic or sexual, varying by manufacturer. Frozen whole adult Artemia were found to carry eggs but could not be hatched. Due to the risk of misidentifications from morphological identification, a 658-bp fragment from the 5ʹ region of the COI gene was amplified from tissue samples. The phylogenetic tree constructed from the COI gene sequences identified distinct clades corresponding to four species: A. franciscana, A. parthenogenetica (both hatched from eggs as viable populations), A. sinica, and A. salina (both identified in food, but not viable). The BLAST analysis indicated that the capsulated  cysts from USA and German manufacturers contained Artemia franciscana, while the Chinese supply contained A. parthenogenetica. Decapsulated cysts from a Chinese manufacturer hatched into A. parthenogenetica. While A. franciscana can be legally imported into New Zealand, A. parthenogenetica is not listed in the Import Health Standard for ‘Fish food and fish bait’ under the Biosecurity Act 1993. The morphological identifications matched the BLAST analysis data for Daphnia. Non-native Daphnia pulex was recorded from live samples from Te Aroha, Hamilton and Wellington (LID5). An Auckland sample and another Wellington sample comprised of native D. carinata s.l. Overall, commercially available fish food from aquarium suppliers can act as a vector for non-native zooplankton to New Zealand.

title: Maori land in Hauraki

authors: Hart, Philip

abstract: Imagining the Hauraki Peninsula to contain payable goldfields and knowing that land to the south of Thames had great agricultural potential, Pakeha were determined to acquire it, and were frustrated by what was considered to be ‘Maori intransigence’. For their part, Maori landowners were justifiably concerned about losing their land, and hindered and delayed opening it to settlement for as long as possible. A major difficulty for officials seeking to acquire land was how to determine boundaries between different blocks and how to identify the true owners when there were rival claims put forward by hapu and individuals. Land purchase agents used a variety of means to get blocks through the land court and then to individualize the title, notably the controversial ‘raihana’ policy, which benefited some landowners at the expense of others. The expensive legal process involved often forced those who had proved their ownership to sell land to pay for their success, a success which resulted in grantees treating the land as their personal property rather than tribal property. Some Pakeha as well as many Maori protested at the unfair process; even James Mackay, the most effective practitioner of raihana, came to lament his success and its consequences for the younger generation of Maori (he blamed the system, not himself). When far too late, it was urged that land should have been leased rather than sold and that proceeds from sales should not have been squandered.
Instead of having commissions of enquiry, as some suggested, the land court system meant that judges determined ownership on the evidence presented to them, even though some owners were not present nor had their interests represented. Sometimes the evidence was false, as was admitted by some witnesses when their perjury was exposed. And in the case of the Ohinemuri district, for which the records survive, when the land was sold to the Crown some Maori received too much money, some too little, and some missed out altogether. The struggles to open Ohinemuri to miners and settlers is examined in detail, revealing that some rangatira expected economic gain and that Te Hira’s party, who opposed the opening, were undermined by some of Te Hira’s followers: being ‘Hauhau’, they refused to take money from the Crown but instead took raihana, meaning goods which were charged against their land in a way they did not understand. Nor did anyone fully understand the system apart from Mackay, whose policy was eventually repudiated by the politicians who had encouraged it previously. Not all land was lost, but because the government did not assist landowners with advice and finance until well into the twentieth century what land that was retained could not be developed adequately.
