On Deciding The Aims and Content of Public Schooling

In this paper, John Tillson defends an approach to deciding the aims and content of public schooling from the critique of Public Reason Liberalism. The approach that he defends is an unrestricted pairing of the Epistemic Criterion and of the Momentousness Criterion. On the Epistemic Criterion, public schooling should align students' credence with credibility. On the Momentousness Criterion, public schooling ought to include content that it is costly for children to lack the correct view about, where they are otherwise unlikely to have it. Public Reason Liberals seek to restrict both the Epistemic and Momentousness Criteria to within a range that is acceptable to politically reasonable citizens. In response, Tillson argues, first, that the considerations that encourage Public Reason Liberalism instead motivate unrestricted versions of the Epistemic and Momentousness Criteria; and, second, that Public Reason Liberalism faces a dilemma, that it either entails absurd consequences or must undermine itself in addressing these.     

The influence of three approaches to feedback on L2 writing task improvement and subsequent learning

This research examined the effects of using rubrics, exemplars, and self-assessment as forms of feedback in an L2 writing development course in English with Chinese speakers. The sample consisted of 114 L2 students at a university in Macau. Participants were randomly assigned to treatment groups and provided feedback on an English writing task using either rubrics, exemplars, self-assessment, or a control condition. The efficacy of these treatments was examined for both performance (on the writing task at hand) and learning (as demonstrated by performance on a new, similar writing task). Results indicate that rubrics and exemplars were effective as compared to the control condition, but the self-assessment approach was not.     

An evaluation framework for cross-lingual link discovery

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9.

Accounting for structure and agency in ‘close-up’ research on teaching,learning and assessment in higher education

This paper examines research into teaching, learning and assessment (TLA) in higher education in terms of structure and agency. It argues that although issues of structure and agency are seen as crucial in social theory, they are very little discussed in research into TLA in higher education and that a consideration of structure and agency raises some important questions about this research and the quality of the explanations that it generates. It is therefore time to reconsider this research from the standpoint of structure and agency so that more sophisticated approaches to researching, and generating explanations of, teaching, learning and assessment in higher education can be developed.     

Assessment for learning: a catalyst for student self-regulation

The development of students as lifelong, self-regulating learners is a valued outcome of higher education. To this end, the current project investigated how students in an undergraduate course experienced and responded to a teaching–learning environment where they were expected to take responsibility for their learning. The pedagogic environment of this course was grounded in strategies and activities associated with assessment for learning (AfL). As such, students were expected to participate in activities that provided them with opportunities to exercise control over their learning. Data gathering comprised individual semi-structured interviews and the collection of artefacts. Findings indicated goals helped students know where they were going; exemplars provided insights into what was expected and what constituted quality work; course activities elicited evidence of learning; dialogic interactions around these generated feedback about understandings and progress; the evaluation of exemplars developed evaluative knowledge, skill and expertise; peer review and feedback provided an authentic context for evaluation and monitoring of works-in-progress. It was concluded that, while each of the AfL strategies contributed to student self-regulation, the full impact of AfL as a catalyst for self-regulated learning was realised in the cumulative and recursive effect these strategies had on students’ thinking, actions and feelings.     

山东省禹城市粮食生产资源利用效率评价

粮食生产资源利用效率研究是实现粮食稳产、高产的前提，也是保障国家粮食安全的理论基础。对不同条件下的作物生产潜力准确估算和适宜的资源利用效率评价是粮食生产资源利用效率研究的核心内容。本文采用PS123作物生长模型进行作物生产潜力计算，根据山东省禹城市实际状况，确定了模型输入参数，计算了研究区玉米、小麦和大豆的光合、光温、气候和气候－土壤生产潜力，采用作物结构订正计算区域粮食生产潜力。考虑粮食生产中光热资源、水资源、土地资源、社会经济资源等方面，从准则层和因子层两个层面构建了粮食生产资源利用效率评价模型，确定了各评价因子的目标值和权重，对禹城市粮食生产资源利用效率进行评价。研究结果表明：　①山东省禹城市光合生产潜力52 784kg/hm²，光温生产潜力11 023kg/hm²，气候生产潜力8 377kg/hm²，气候-土壤生产潜力6 450kg/hm²，对这3种作物的实际产量进行结构订正得到该市1999年～2001年粮食平均现实生产能力为6 244kg/hm²，禹城市粮食生产潜力较大；　②制约粮食生产稳产、高产主要自然因子为水资源的不合理利用，劳动生产率、化肥利用率和产投比的低下是主要的社会经济限制因子。根据不同的限制性因子，本文提出了单项资源利用技术改进措施。
