Sunyono; Yuanita, L.; Ibrahim, M. – Science Education International, 2015
The aim of this research is identify the effectiveness of a multiple representation-based learning model, which builds a mental model within the concept of atomic structure. The research sample of 108 students in 3 classes is obtained randomly from among students of Mathematics and Science Education Studies using a stratified random sampling…

Chang Rundgren, Shu-Nu; Yao, Bao-Jun – Asia-Pacific Forum on Science Learning and Teaching, 2014
Based on the importance and widely use of visualization in science, this article has a three-fold aim related to the terms of visualization, representation and model that in recent years have been introduced to the field of science education without clear differentiation. Firstly, the three terms are discussed with examples to provide a common…

Bryce, T. G.; Blown, E. J. – Science & Education, 2016
This article notes the convergence of recent thinking in neuroscience and grounded cognition regarding the way we understand mental representation and recollection: ideas are dynamic and multi-modal, actively created at the point of recall. Also, neurophysiologically, re-entrant signalling among cortical circuits allows non-conscious processing to…

Gilbert, John K.; Boulter, Carolyn; Rutherford, Margaret – International Journal of Science Education, 1998
Seeks to identify some of the issues associated with the role of models in scientific explanations. Develops a typology of explanations and explores the notion of appropriateness in scientific explanations. Investigates the nature of models and their contribution to explanations. (DDR)

Greca, Ileana Maria; Moreira, Marco Antonio – International Journal of Science Education, 2000
Reviews science education research into representations constructed by students in their interactions with the world, its phenomena, and artefacts. Features discussions of mental models, conceptual models, and the activity of modeling. (Contains 30 references.) (Author/WRM)

Discenna, Jennifer – 1998
This research study focused on the knowledge structure of the domain of physics by describing the knowledge of experts, intermediates, and novices. In order to investigate these representations, a reiterative categorization task was employed using novice, intermediate, and expert subjects (N=27). The categories were classified as theory-, model-,…

Erduran, Sibel – 1998
This paper reports on an interdisciplinary theoretical framework for the characterization of models and modeling that can be useful in application to chemistry education. The underlying argument marks a departure from an emphasis on concepts that are the outcomes of chemical inquiry about how knowledge growth occurs through modeling in chemistry.…

Coll, Richard K.; Treagust, David F. – Research in Science and Technological Education, 2002
Explores whether exposure to increasingly sophisticated mental models at different points in a chemistry education class showed up in patterns of preference and use of models in interpreting physical properties and phenomena. (Contains 92 references.) (DDR)

Mioduser, David; And Others – Computers in Human Behavior, 1996
Presents a framework characterizing cognitive models generated by sixth-grade students for simple opening/closing control mechanisms, like the elevator door. The students' conceptions, missing conceptions, and misconceptions are analyzed at three levels: device knowledge; perception of the control process; and perceptions of information flow. (LAM)

Camacho, Fernando Flores; Cazares, Leticia Gallegos – Science Education, 1998
Illustrates the construction of conceptual models on pressure and flotation using high school students' previous ideas on these concepts. Identifies three models and uses them to analyze students' ideas about physical phenomena and to recognize the inferential structure they use. Contains 28 references. (DDR)

Kuo, Rita; Lien, Wei-Peng; Chang, Maiga; Heh, Jia-Sheng – Educational Technology & Society, 2004
This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Bishop, Joyce Wolfer – 1997
This study explores seventh- and eighth-grade students' thinking about mathematical patterns. Interviews were conducted in which students solved problems about sequential perimeter and area problems modeled with pattern blocks and tiles, generalized the relationships related to the patterns and represented the relationships symbolically,…
