常微分方程理论中的一个经典问题

实解析微分方程x=f(t,x0的解不一定实解析，实多项式微分方程x=p(t,x)的解一定实解析，文章修正了在复微分方程到微分方程的推理中引起的一个误解。     

How schools can move beyond exclusion

Healthy learning environments for young people are underpinned by respectful relationships. Unfortunately, Australian students who do not form reasonable relationships with peers and staff are unlikely to benefit from being at school. These students tend to disengage and are often excluded. However, a growing number of Australian schools have moved beyond exclusion as their default response in dealing with such students. In asking themselves After exclusion what? some Australian schools have found that one answer is to create an onsite enabling space as an integral part of their student well-being practice. Drawing on an Australian Research Council-funded research project involving the University of Melbourne, Hands On Learning Australia and a wider team of partners, this paper introduces the conceptual framework of enabling spaces to explore respectful relationships through the tripartite lens of connection, control and meaning. Enabling spaces, built on respectful relationships, foster a sense of belonging in students, encourage and develop self-efficacy, and provide a context for students to derive a sense of purpose. In this way, they can help young – often disadvantaged – people maintain their connection with mainstream schooling. We argue that these elements are common features of all enabling spaces, and discuss the Hands On Learning method as an illustrative case study.     

Online peer-assessment quality control: A proactive measure,validation study,and sensitivity analysis

Despite the generally positive learning effects of peer-assessment (PA), there are some undesirable signs and troublesome behavior needed to be addressed (e.g., biased judgments, superficial-level engagement). Anchoring on the concept of individual accountability and assessment validity, while attending to other important elements (including both subjective and objective criteria, individuals’ differentiation ability across the points on the assessment scale, and completion rate), a measure was proposed for PA quality control. This measure consists of four indexes/variables and enables the quantification and appraisal of the peer-assessor’s performance. A validation study involving two classes of undergraduate students (N = 103) engaged in the assessment of peers’ oral presentations was conducted to evaluate the effects of the proposed measure. The statistically significant results confirmed the efficacy of the proposed measure to promote better online PA performance. Additionally, to assess its applicability, sensitivity analysis targeting different aspects of our proposed measure (i.e., different plausible weighting for each of the associated indexes/variables, different correlation values between peers’ and the teacher’s ratings, and different bound values for the scale) was conducted. All significant results of the 281 test cases further substantiated the applicability and efficacy of our proposed measure under various assessment schemes for PA quality control.
