摘要
当前的几何改革试图通过让学习者“掌握空间”(Freudenthal, 1973;Hansen et al., 1998, p. 241)。本研究接受了这一挑战,在Flatland周围的一系列调查中,对21名参与空间和维度概念的八年级学习者进行了问题化活动作为一种体现现象的调查。使用现象学研究方法,我们研究了课堂话语、学习者的博客文章、生活经验描述和访谈。分析揭示了问题化活动的三种表现形式:挑衅、僵局、质疑和猜测活动。当学习者将自然连续空间与K - 12设置中强调的离散空间概念并置时,通过感知-运动-想象活动证明了体现。
Manifestations of Middle School Learners’ Problematization Activity as an Embodied Phenomenon
Current reforms in geometry seek to challenge prevailing ideas about “what it means to do mathematics” (Stephan et al., 2015, p. 139) by engaging learners in “the grasping of space” (Freudenthal, 1973; Hansen et al., 1998, p. 241). This study takes up this challenge by investigating problematizing activity as an embodied phenomenon among 21 eighth-grade learners who engaged with spatial and dimensional concepts during a series of investigations around Flatland. Using a phenomenological research approach, we examined classroom discourse as well as learners’ blog postings, lived-experience descriptions, and interviews. The analysis revealed three manifestations of problematizing activity—provocation, impasse, and questioning and conjecturing activity. Embodiment was evidenced through perceptuo-motor-imaginary activity as learners juxtaposed naturally continuous space with discrete notions of space emphasized in K−12 settings.
