Cognitive activities in complex science text and diagrams 总被引：1，自引：0，他引：1
Jennifer G. Cromley Lindsey E. Snyder-Hogan Ulana A. Luciw-Dubas 《Contemporary educational psychology》2010
Ainsworth’s (2006) DeFT framework posits that different representations may lead learners to use different strategies. We wanted to investigate whether students use different strategies, and more broadly, different cognitive activities in diagrams vs. in running text. In order to do so, we collected think-aloud protocol and other measures from 91 beginning biology majors reading an 8-page passage from their own textbook which included seven complex diagrams. We coded the protocols for a wide range of cognitive activities, including strategy use, inference, background knowledge, vocabulary, and word reading. Comparisons of verbalizations while reading running text vs. reading diagrams showed that high-level cognitive activities—inferences and high-level strategy use—were used a higher proportion of the time when comprehending diagrams compared to when reading text. However, in running text vs. diagrams participants used a wider range of different individual cognitive activities (e.g., more different types of inferences). Our results suggest that instructors might consider teaching students how to draw inferences in both text and diagrams. They also show an interesting paradox that warrants further research—students often skipped over or superficially skimmed diagrams, but when they did read the diagrams they engaged in more high-level cognitive activity. 相似文献

Simulation environments make it possible for science and engineering students to learn to interact with complex systems. Putting these capabilities to effective use for learning, and assessing learning, requires more than a simulation environment alone. It requires a conceptual framework for the knowledge, skills, and ways of thinking that are meant to be developed, in order to design activities that target these capabilities. The challenges of using simulation environments effectively are especially daunting in dispersed social systems. This article describes how these challenges were addressed in the context of the Cisco Networking Academies with a simulation tool for computer networks called Packet Tracer. The focus is on a conceptual support framework for instructors in over 9,000 institutions around the world for using Packet Tracer in instruction and assessment, by learning to create problem-solving scenarios that are at once tuned to the local needs of their students and consistent with the epistemic frame of “thinking like a network engineer.” We describe a layered framework of tools and interfaces above the network simulator that supports the use of Packet Tracer in the distributed community of instructors and students. 相似文献

网络已成为民意表达的重要场所,网络舆情深刻地影响着公共政策的评价机理,其功能正得到前所未有的发挥。其中积极影响的原因包括公共政策评价主体系统的缺陷催热网络问政;网络舆情对公共政策产生强大的舆论压力。消极影响的原因则是政府及其公务人员的角色定位不当;网络舆情的非理性。通过分析提出规范网络舆情发布,加强网民素质教育,增强政策的透明度等对策建议,来充分发挥网络舆情对公共政策评价的积极影响。建立线上快速应急机制以及责任追究制度,以规避网络舆情对公共政策评价的消极影响。 相似文献

新型冠状病毒（COVID-19）疫情爆发期间,涌现出了众多的抗疫意见领袖。通过对意见领袖话题传播和演化进行分析研究,可以为网络舆情治理和疫情防控提供理论和知识支撑。采用N-Gram语言模型和Shingling相似度算法相结合的方式进行话题检测,再通过Neo4j图数据库存储与检索意见领袖、话题、事件等多维实体特征,构建以意见领袖为核心的话题图谱。实验结果表明,话题准确率达82.3%,召回率达81.6%,与传统Single-Pass聚类相似度算法相比均有所提高。通过对图谱分析,能够简单直观地展示出不同实体间多维舆情关系。同时,可以提高检索速度和分析效率,符合舆情传播客观规律。 相似文献

ABSTRACT The purpose of this study is to profile four university science instructors who utilized action research as a means of learning how to develop and integrate a novel curriculum innovation – engineering design – in their science courses. Data included curriculum maps, lesson plans, notes from group meetings, and instructor reflections. Data analysis included document review and content analysis. Findings from this study suggest that action research effectively enabled the instructors to 1) establish shared ownership of the project goal – to improve preservice teachers’ learning of science through engineering design; 2) continuously test, revise, and recalibrate their shared instructional products; and 3) leverage multiple sources of innovation. Knowledge generated and used by the instructors represented different kinds of knowledge and distributed expertise resulting in products that were more useful and of higher quality than products created by individuals working alone. Consequently, this resulted in increased use of the products and increased instructor commitment to improve them over time. By simultaneously engaging in research and consequently taking specific action to inform their practice, science instructors in this study successfully created shared instructional products that both guided and enhanced their classroom teaching. 相似文献

In this study, we used qualitative methods to help us better understand the experiences of instructors as they are persuaded
to adopt a course management system and integrate it into their teaching. We discuss several patterns explaining how instructors
implemented Blackboard, a CMS, by experimenting with individual features, facing both technical and integration challenges,
and attempting to adapt Blackboard features to match their goals and practices. We also give explanations for why instructors
either (a) embraced the tool and grew more dependent on it, (b) reduced their use of the tool to only some features, or (c)
discontinued the tool and actively sought replacement options. In this paper we explain why instructors fell into any one
of these three areas and what implications this may have for training and support needs. 相似文献

In this article, we explore the transition from philosophical and theological manifestos to their practical and educational implementation as we analyze the official American Reform-Judaism discourse as curricular text. This analysis provides a tool for a discussion of the relationships between vision and its implementation particularly for educators and leaders. We highlight the possibilities of dialogue among educators, rabbis-in-training, and leaders to aid in the formation of new visionary documents and, in doing so, affect the dynamics of paving new directions. We demonstrate a model that may be used to investigate such translations from vision to a lived experience and back to reconstruction of a vision. 相似文献

The Mathematics education community has long recognized the importance of diagrams in the solution of mathematical problems.
Particularly, it is stated that diagrams facilitate the solution of mathematical problems because they represent problems’
structure and information (Novick & Hurley, 2001; Diezmann, 2005). Novick and Hurley were the first to introduce three well-defined types of diagrams, that is, network, hierarchy, and matrix,
which represent different problematic situations. In the present study, we investigated the effects of these types of diagrams
in non-routine mathematical problem solving by contrasting students’ abilities to solve problems with and without the presence
of diagrams. Structural equation modeling affirmed the existence of two first-order factors indicating the differential effects
of the problems’ representation, i.e., text with diagrams and without diagrams, and a second-order factor representing general
non-routine problem solving ability in mathematics. Implicative analysis showed the influence of the presence of diagrams
in the problems’ hierarchical ordering. Furthermore, results provided support for other studies (e.g. Diezman & English, 2001) which documented some students’ difficulties to use diagrams efficiently for the solution of problems. We discuss the findings
and provide suggestions for the efficient use of diagrams in the problem solving situation. 相似文献
