1 Designing Effective Multi - Representational Learning Environments
نویسنده
چکیده
ion has been defined in a number of different ways. One common sense of the term is as ‘subtraction’ where the emphasis is on extracting only a portion of original representation. For example, Giunchiglia & Walsh (1992) in defining abstraction refer to ‘throwing away details’. More completely, they (informally) define abstraction as: 1. The process of mapping.... the ground representation onto a new representations called the abstract representation which: 2. helps deal with the problem in the original search space by preserving certain desirable properties and

Effective Environmental Factors on Designing Productive Learning Environments
Educational spaces play an important role in enhancing learning productivity levels of society people as the most important places to human train. Considering the cost, time and energy spending on these spaces, trying to design efficient and optimized environment is a necessity. Achieving efficient environments requires changing environmental criteria so that they can have a positive impact on ...
متن کاملDesigning Reciprocative Dynamic Linking to improve learners’ Representational Competence in interactive learning environments
Learning from interactive learning environments enriched with multiple external representations (MERs) is often beneficial. The learning benefits of MERs highly rely on the development of Representational Competence. Representational Competence refers to an ability to translate and see relations between MERs. The relevant research findings have consistently reported learners’ difficulty in rela...
متن کاملExamining the Effects of Different Multiple Representational Systems in Learning Primary Mathematics
Multi-representational learning environments are now commonplace in schools and homes. Research that has evaluated the effectiveness of such environments shows that learners can benefit from multiple representations once they have mastered a number of complex tasks. One of the key tasks for learning with multiple representations is successful translation between representations. In order to exp...
متن کامل1 How should we evaluate complex multimedia environments ?
Early research with multimedia environments questioned whether these environments are effective in supporting learning. More recently it has been acknowledged that this question should really be “under what conditions, for which learners, performing which tasks and expecting what outcomes is learning with multimedia environments effective?”. However, while the argument has become more sophistic...

Multiple representations and multi-media can support learning in many dierent ways. In this paper, it is claimed that by identifying the functions that they can serve, many of the con ̄icting ®ndings arising out of the existing evaluations of multi-representational learning environments can be explained. This will lead to more systematic design principles. To this end, this paper describes a fu...
