Using learner generated examples to introduce new concepts

In this paper we describe learners being asked to generate examples of new mathematical concepts, thus developing and exploring example spaces. First we elaborate the theoretical background for learner generated examples (LGEs) in learning new concepts. The data we then present provides evidence of the possibility of learning new concepts through a symbiosis of induction and abduction from experience and deduction from the relationships generated in exemplification. In other words, experience can be organised in such a way that shifts of understanding take place as a result of learners’ own actions. Actions, in this context, include mental acts of organisational reflection.

Fibonacci数列的性质及矩阵证明

运用矩阵方法证明了Fibonacci数列的通项公式及Cassini公式,并对Cassini公式进行了推广,进而得到一个结论-由连续的m×r个Fibonacci数的k次方所组成的m行r列矩阵D m×rk,当r,m≥k 1,k=1,2,3时,矩阵的秩都为k 1．

西方可持续性理论研究的最新进展及其趋势

过去20年来,可持续性概念在生态、经济、政治、社会等领域广泛应用,它代表着人类社会在资源约束条件下,对自身生存与发展的一种哲学化思考.本文拟从以下三个维度对可持续性理论的文献进行研究:关于可持续性概念涵义的演变:可持续性研究中的全球化语境到区域化语境的转化;关于可持续性指标研究的进展,从而总结出可持续性概念的涵义从泛化应用到哲学化理念的演变路径.     

邓小平社会主义本质论之我见

邓小平社会主义本质论的提出有一个过程.这一论述是对社会主义本质的新概括.对邓小平的新概括,我们不能仅仅限于字面上的理解,而必须历史地、全面地、有针对性地加以理解和掌握.新概括把解放生产力和发展生产力当作社会主义的首要本质,有其深刻原因.新概括没有提实行公有制和按劳分配,有其特殊用意.新概括中的五句话是一个不可分割的有机整体.

Theme-Park Psychology: A Case Study Regarding Human Intelligence and Its Implications for Education

We introduce in this article the construct of theme-park psychology which we define as psychological theory and research drawn only from limited and unrepresentative samples of participants, tasks and situational contexts within the context of worldwide populations. Results obtained from limited populations, tasks, and situational contexts often are inappropriately generalized and then used as a basis for educational policy. In theme-park psychology, easy-to-study populations, tasks, and situational contexts repeatedly may show the same patterns in data, leading to tantalizing generalizations that are nevertheless wrong. We describe studies by ourselves and by others with respect to human intelligence that illustrate our views and that cast doubt on traditional notions.
