This article presents a cohesive, empirically grounded categorization system differentiating the types of generalizations students constructed when reasoning mathematically. The generalization taxonomy developed out of an empirical study conducted during a 3-week teaching experiment and a series of individual interviews. Qualitative analysis of data from teaching sessions with 7 seventh-graders and individual interviews with 7 eighth-graders resulted in a taxonomy that distinguishes between students' activity as they generalize, or generalizing actions, and students' final statements of generalization, or reflection generalizations. The three major generalizing action categories that emerged from analysis are (a) relating, in which one forms an association between two or more problems or objects, (b) searching, in which one repeats an action to locate an element of similarity, and (c) extending, in which one expands a pattern or relation into a more general structure. Reflection generalizations took the form of identifications or statements, definitions, and the influence of prior ideas or strategies. By locating generalization within the learner's viewpoint, the taxonomy moves beyond casting it as an activity at which students either fail or succeed to allow researchers to identify what students see as general, and how they engage in the act of generalizing. 相似文献

论教育目标分类学中的“马氏理论”对“布氏框架”的超越 总被引：1，自引：0，他引：1
布卢姆的分类学开创了教育目标分类学研究的先河,影响了20世纪的教育。在当代教育体系中,"分类而教"已成为教学设计者的共识。2001修订版的布氏分类学沿袭了1956版的基本思路,对各要素进行了重新思考,强调有意义的学习,有着较强的科学性和实用性,是布氏分类的重大发展。而与2001修订版产生于同期的马扎诺分类,则以更为独特的视角,从人的行为模式出发,以人的意识控制程度作为依据,将人类学习活动的自我、元认知、认知和知识四大系统纳入一个统一的系统,构筑了一种层次分明而又合为一体的教育目标分类学。新分类力图打破布氏分类的"框架"局限,致力于"理论"的构建。他的分类理论反映了信息社会主流的知识观和以学习者为中心的教育理念。追求统一的心理学基础,提升了学习者学习过程中元认知的地位与作用,并把"自我"作为教育目标分类的最高层次,具有开拓性的意义,突破了以往教育目标分类"要素模式"的局限,丰富了分类学研究的内涵,体现了对原有的"布氏框架"的超越。 相似文献

Active learning pedagogies play an important role in enhancing higher order cognitive skills among the student community. In this work, a laboratory course for first year engineering chemistry is designed and executed using an inquiry-based learning pedagogical approach. The goal of this module is to promote higher order thinking skills in chemistry. Laboratory exercises are designed based on Bloom's taxonomy and a just-in-time facilitation approach is used. A pre-laboratory discussion outlining the theory of the experiment and its relevance is carried out to enable the students to analyse real-life problems. The performance of the students is assessed based on their ability to perform the experiment, design new experiments and correlate practical utility of the course module with real life. The novelty of the present approach lies in the fact that the learning outcomes of the existing experiments are achieved through establishing a relationship with real-world problems. 相似文献

This article presents a beginning effort to build a taxonomy for constructed-response test items. The taxonomy defines the categories for various item formats in three distinct dimensions: (a) type of reasoning competency employed, (b) nature of cognitive continuum employed, and (c) kind of response yielded. Each dimension is described, and the reasons for incorporating it into the taxonomy are explained. A theoretical rationale for the taxonomy is developed, and advantages and shortcomings of its use are noted. 相似文献

I present an expanded taxonomy of sorting algorithms that is based upon Merritt's inverted taxonomy [1] and Lau's logic‐based derivations [2, 3]. The inverted taxonomy was based on a higher level, more abstract, and conceptually simple top‐down approach to sorting than the traditional taxonomy such as that given by Knuth [4], Work done in automatic program synthesis suggested the approach. Sorts were divided into two categories, hardsplit/easyjoin and easysplit/hardjoin, of which quicksort and mergesort are the canonical examples, respectively. Lau's [2, 3] logic‐based derivations strengthen the inverted taxonomy by deriving comparison‐based sorting algorithms that fall into the two categories of hardsplit/easyjoin and easysplit/hardjoin. Moreover, they expand the taxonomy by deriving distributive algorithms in a symmetric way. 相似文献
