“Here the Scientists Explain What I Said.” Coordination Practices Elicited During the Enactment of the Results and Discussion Sections of Adapted Primary Literature

Adapted primary literature (APL) is a novel text genre that retains the authentic characteristics of primary literature. Learning through APL represents an educational intervention with an authentic scientific context. In this case study, we analyzed the 80-min discourse developed during the enactment of an article from an APL-based curriculum in biotechnology in one class, and examined epistemic practices used by students during their meaning-making of the Results and Discussion sections of the article. Specifically, we examined coordination practices, by which students connected elements belonging to different epistemic status or context (theory, data, experimental stages, biotechnological applications and text). The application of coordination practices was identified more than 70 times during the lesson. In the context of the Results section, the students displayed research-oriented coordination practices, which were frequently associated with claims of comprehension difficulty. In the context of the Discussion section, students displayed text-oriented coordination practices, associated with analysis of the text characteristics. We are suggesting that the research-oriented coordination practices and some of the text-oriented ones enabled the emergence of authentic scientific practices and learning by inquiry. Another type of text-oriented coordination practice enabled reflection on scientists’ experimental processes, enabling learning science as inquiry. The enactment model of APL used here allowed for both the emergence of the two dimensions of inquiry learning and the promotion of scientific literacy in the fundamental and derived senses.     

试析库切小说中的父亲形象

库切小说中对传统父亲形象进行了解构,传统意义上的权威化身的父亲形象沦为软弱无能与丑陋堕落的同义词。父亲形象在叙事策略上也沦为边缘角色甚至处于"无名"状态,这隐喻着殖民主义和白人权威的坍塌和社会伦理结构的重组。     

论《史记》中的智者人格形象

司马迁在《史记》中创造性地塑造了一批异于传统贤者、仁者、勇者——＂智者＂的人格形象。这些＂智者＂洞察时势、筹计画策以成事功,是时代的风云人物,他们有执着的目标,坚定的意志和敏锐的洞察力,能超越世俗常态而直取本质,他们因时因势而起,是时代的弄潮儿。时代造就了智者的人格内涵与取向,同时也在其中打下了鲜明的时代印迹。智者形象是司马迁的发现和创造,是其对文学的一大贡献。

惠女绘画形象创作的反思与拓展

当下,惠女形象的绘画图式,依然以她一贯的坚韧与美丽的图像符号,在国内各种画展频繁出现。在这种近乎模式形象创作的延续下,惠女形象除了本身符号般的象征以及民俗表象意义外,很难进一步揭示惠女更为鲜活的人性元素。本文通过对惠女绘画创作体验以理论的思考,尝试对其文化传承与超越进行补充诠释,从而体现与时代相吻合的文化意识,并期待这个地方典型民俗审美形态的文化得到更好的弘扬。
