Use of External Representations in Reasoning about Causality
This research investigated if diagrams aid in deductive reasoning with formal causal models. Four studies were conducted exploring participants' ability to discover causal paths, identify causes and effects, and create alternative explanations for variable relationships. In Study 1, abstract …

Individual differences in learning strategies and external representations
… specifically taught and in this thesis called 'representations' are used by individuals to work out problems. There are two parts to the thesis. The first part used wordlists and learning strategies to assist subjects in learning lists of words. The second part of the thesis used problems and no …

Measuring the effect of user-generated external representations during sensemaking in electronic environments
… whether stored internally as a mental model or externally by using maps or tables, for example. The latter is generally assumed to be helpful, but little is known about the way in which external representations actually affect the sensemaking process. Despite the literature explicitly …

Kooperatives Lernen in Videokonferenzen
… scripts enhance the construction of shared external representations and foster learning outcomes. The results indicate that content schemes as well as cooperation scripts foster the construction of shared external representations. Furthermore, the learners with a cooperation script had …

Hand-Held Cognition: Does Learning Suffer When an External Representation Interface Style is Used?
Previous research has shown that external representation of information facilitates cognitive processing by requiring less recall and reducing the need for working memory. The assumption is that all task types are better performed with an external representations interface style. Research conducted …

USE OF BIOMETRICS TO DETERMINE BIOCHEMISTRY KNOWLEDGE LEVEL DIFFERENCES IN READING AND PROCESSING METABOLIC PATHWAYS
… areas of chemistry and biochemistry commonly use external representations to enhance learning for students. The use of schematics and representations for illustrating metabolic pathways is a familiar image in most biochemistry textbooks. These external representations can be the key to student …

Perspectives of the role of the body in the design process : observations from an experiment
… self. It is through the body that we construct external representations (embodied in drawings or gestures) that are essential to the design thinking process. The conclusion considers how these observations should impact design inquiry undertakings, in particular the necessity of fostering a more …

Exploring middle school students' sensemaking of a gesture-augmented computer simulation depicting thermal conduction
… which shows how students converted the external representations of the simulation into internal representations, revealed how and when students talked about external representations of the simulation as part of their conceptual modeling. Third, the framing dimension involved two …

Synthetic social relationships for computational entities
… two main questions: *What kinds of internal and external representations are necessary for computational entities to form social relationships like those formed by animals? *How can people participate in and direct the relationships of these entities? To explore these questions, I designed and …

Unterstützung multimedialen Lernens : Instruktionsdesign zur Förderung der Kohärenzbildung beim Wissenserwerb mit Texten und dynamisch-interaktiven Bildern
In multimedialen Lernumgebungen werden Informationen meist sowohl in sprachlicher als auch in bildhafter Form dargeboten. Insbesondere bildhafte Informationen sind dabei häufig dynamisch gestaltet und können von Lernenden interaktiv verändert werden. Mit diesem Einsatz multipler dynamischer und …

Distributed thinking across mind and media: creative design in traditional tools and generative design
… the iterative reasoning across internal and external visual representations, is the engine for creative design across engineering, architecture, and art. This highlights the distributed nature of visual thinking across mind and media. Internal resources such as visual working memory and …

Las representaciones pictóricas como problema de aprendizaje: el caso de equilibrio químico
… are not equivalent, but complementary; 3) external pictorial representation are full of content but the relationship between Sign and Referent is abstract and arbitrary in academic contexts, so cultural processes are necessary for an individual to establish that relationship. However, …

Unterstützung des Design Problem Solving: Einsatz und Nutzen einfacher externer Hilfsmittel in den frühen Phasen des konstruktiven Entwurfsprozesses
… is largely associated with the use of simple external representations such as sketches and material (physical) models. In the represented thesis the use and functions of such external aids were investigated at first with a questionnaire study consulting designers (N = 106) of different …

Effects Of Interdisciplinary Designers Reflecting-In-Action During Design
… they took stock in and reacted to external representations, which were rich in context, information, and constraints. Participants interacted with information and a lack of information, which kept the design project moving forward. Participants moved the design forward toward …

Unterstützung von Kohärenzbildung beim kooperativen und individuellen Lernen mit externen Repräsentationen
Folgende Forschungsfragen lagen der Arbeit zugrunde: (1) Ist das Interpretieren oder das Konstruieren externer Repräsentationen (ERn) lernförderlicher? (2) Profitieren Lernende von einer Anleitung zur Elaboration des Zusammenhangs alternativer Repräsentationen?. (3) Ist kooperatives Problemlösen …

Enhancing learning through opening the group model in a synchronous computer-based environment.
… Bar charts and textual explanations are used as external representations of learning performance as a group. The system was implemented and tested in two versions: paper-based, for the plausibility of the content and the user interface; and computer-based, for comparing the learning results among …
