    (Sharon) From Paper:
    Intelligent Tutoring Systems with Multiple Representations and Self-Explanation Prompts Support Learning of Fractions (by Martina A. RAU,Vincent ALEVEN, and Niko RUMMEL)

    "In the educational psychology literature, there is a substantial amount of evidence demonstrating that the use of multiple representations of learning content (MRs) can significantly enhance student learning in complex domains, compared to learning with only a single representation. However, simply providing a learner with multiple representations (e.g., textual description plus graphic, or multiple graphical representations [MGRs]) does not necessarily result in flexible knowledge acquisition. It has been argued that learners must perform a number of cognitive tasks in order to benefit from MRs. In particular, learners acquire a deep understanding only if they are able to link MRs of the same concept and to coordinate between them. If students fail to integrate the information from the different representations, their learning may be jeopardized. Unfortunately, it has been demonstrated that most students do not spontaneously attempt engage in integration activities."

    (Sharon)BASIC MRs introduction in Physics education area

    Why do you want to use MRs?
    • Multiple Intelligences
    Students learn in different ways. Different representations are compatible with different learning styles.
    • Visualization for the brain
    Physical quantities and concepts can often be visualized and understood better using concrete representations.
    • Help construct another type of representation
    Some concrete representations help in constructing a more abstract (often mathematical) representation.
    • Some representations are useful for qualitative reasoning
    Qualitative reasoning is often assisted by using a concrete representation.
    • Abstract math representations are used for quantitative reasoning
    A mathematical representation can be used to find a quantitative answer to a problem.

    （Sharon）From Paper: Multiple Representation Skills and Creativity Effects on Mathematical Problem Solving using a Multimedia Whiteboard System (by Wu-Yuin Hwang, Nian-Shing Chen, Jian-Jie Dung, Yi-Lun Yang)

    “The meaning of representation can be different in different contexts. There are external representations (real world) and internal representations (mind). In psychology, representation means the process of modeling concrete things in the real world into abstract concepts or symbols. Jonassen (2000) also interpreted mental models as complex mental representations composed of numerous kinds of mental components including metaphorical, visual-spatial, and structural knowledge.”

    “Some students favor visual or concrete representations, while others favor symbolic or abstract representations. Normally, students with good problem solving abilities are those that can skillfully manipulate their language translation and representations (vocal), picture representation (picture, graphic) and formal representation (sentence, phrase, rule and formula). On the other hand, students with low problem solving abilities are always having difficulty with translation and representation in problem solving. Furthermore, different students have different learning styles for acquiring knowledge. It is better for teachers to adopt different teaching strategies to promote students performing multiple representations in class, thereby enhancing learning performance (Cai & Hwang, 2002).”

    Using multiple representations within a viewpoint

    You could download this paper from:

    "The objective of this research is to aid this reconciliation and integration within the context of information systems design. That is, to facilitate the use of multiple modelling representations for describing a phenomenon. To achieve this objective, the author has chosen an approach based upon translating descriptions of a phenomenon between different representations. This thesis provides several important contributions in the area of information system design using multiple representations. Related work in the area is reviewed, and from this review is derived a terminology based on viewpoint-oriented methods that provides a consistent framework for the discussion of multiple representations."
