Modeling Theory

Modeling theory is a research-based, pedagogical theory, grounded in cognitive science and the philosophy of science. It holds that conceptual models, which represent patterns in the structure or behavior of physical systems, are the best vehicles of thought for students and scientists alike, and that science education is most effective when it focuses on model construction and deployment just like scientific research does.


From a scientific perspective, modeling theory holds that model construction and deployment are major processes of scientific inquiry, and that scientific theory is put together in a middle-out, model-centered structure. A scientific model is a conceptual system mapped, within the framework of a given theory, onto a specific pattern in the structure or behavior of a number of physical systems so as to reliably represent the pattern in question, and serve specific functions in its regard. A model may serve an exploratory function (pattern description, explanation, post-diction and/or prediction), and/or an inventive function (pattern reification through control or change of existing physical systems and phenomena, and/or invention of new ones).


From a cognitive perspective, modeling theory maintains that the most meaningful knowledge about the physical world is experiential knowledge (i.e., knowledge acquired through transaction with physical systems and phenomena) that people develop through reflective thinking and self-regulation. Through such transaction that may involve engagement with other people, every person develops a particular paradigm for representing, thinking about, and interacting with, physical systems and phenomena.


Students’ paradigms are grounded more in naïve realism than scientific realism. The object of science education is thus to help individual students curtail naïve realism and build up scientific realism to realistic levels. According to modeling theory, this can best be achieved in experiential learning cycles, under teacher mediation, that explicitly aim to help students develop necessary tools and skills of modeling inquiry, and structure the content of any course of science around a few basic models.


Prof. Halloun began his work on modeling theory in 1981, at Arizona State University, as part of his PhD dissertation, The Use of Models in Teaching Newtonian Mechanics (1984).

In an analysis of research published in the eighties and nineties, Taconis, Ferguson-Hessler & Broekkamp (JRST, 2001) came to the conlusion that Halloun’s modeling approach tops the list of best practices for improving student problem solving abilities in science.

A special double issue of Science & Education appeared on modeling in 2007 (Vol. 16, Nos. 6, 7).



Modeling Theory in Science Education. (2004/2006). Dordrecht: Kluwer Academic Publishers / Springer.

Any scientific theory can be organized around a limited set of basic models that represent particular patterns in the structure or behavior of physical realities. Students develop sustainable, meaningful and productive understanding of scientific theory when they are engaged in structured experiential learning cycles for model construction and deployment, and explicitly guided to reflect on, and insightfully regulate their own naïve knowledge and mental processes.   Synopsis


Apprentissage par Modélisation : La Physique Intelligible. (2001). Beyrouth, Liban : Phoenix series / Librairie du Liban Publishers.

Toute théorie scientifique peut être organisée autour d’un nombre limité de modèles de base qui représentent des patterns particuliers dans la structure ou le comportement de réalités physiques. Les étudiants de tous niveaux apprennent la physique d’une façon intelligible lorsqu’ils sont dirigés à s’enquérir de la réalité par modélisation suivant une dialectique réflexive et régulatrice qui leur permet de transcender leur sens commun et évoluer vers le monde de la science.   Synopsis

From Modeling Schemata to the Profiling Scheman: Modeling across the Curricula. (2011). In: Khine & Saleh (Eds), Models and Modeling in Science Education. Boston: Springer.

This chapter outlines the cross over to Profile Shaping Education from Modeling Theory, a research-based pedagogical theory developed by this author that promotes mediated experiential learning of model-laden theory and inquiry in science education. Modeling schemata are generic tools that students use for systematic construction and deployment of scientific concepts and models. Under PSE (and subsequently under SCE), these schemata have been extrapolated beyond the boundaries of science, and a single profiling schema (system schema under SCE) has emerged as a major tool to set and deploy benchmarks or outcomes that need to be accomplished in any educational field, and at any grade level.   Full Text


Technologies de modélisation pour un apprentissage intelligible des sciences. (2008). Les TIC et l’émergence des stratégies technologiques dans l’enseignement supérieur. Baabda, Liban : Université Antonine.

La théorie de modélisation est une théorie d’apprentissage et d’enseignement des sciences qui pourrait permettre à la technologie d’améliorer la qualité de l’apprentissage. Conformément à cette théorie, le but principal de la technologie en éducation scientifique est d’ouvrir la boîte noire qui se présente dans l’enseignement traditionnel, et qui comporte les processus de pensée et de recherche scientifiques les plus importants, les processus de modélisation.   Texte Intégral


Mediated modeling in science education. (2007). Science & Education, 16 (7), 653-697.

Modeling theory is a pedagogical theory that promotes mediated experiential learning of model-laden theory and inquiry in science education. Students develop experiential knowledge about physical realities through interplay between their own ideas about the physical world and particular patterns in this world. Under teacher mediation, they represent each pattern with a particular model that they develop through a five-phase learning cycle, following particular modeling schemata of well-defined dimensions and rules of engagement.   Full Text


Model-centered, assessment-guided learning and instruction in science. (2007). Proceedings of the 5th Greek Conference on Science Education and Technology. Ioannina, Greece.

Meaningful and equitable learning of science is achieved when: (a) course materials are aligned with scientific theory and inquiry, and (b) instructors systematically rely on assessment to insightfully mediate student learning. Our research shows that this can best be achieved when modeling schemata are systematically used: (a) to structure course content around a few basic models, and promote model construction and deployment in the classroom, and (b) to systematically assess and regulate student knowledge throughout well-structured modeling cycles.   Full Text


Modeling theory for paradigmatic evolution. (2004). Proceedings of the 12th annual meeting of the Southern African Association for Research in Mathematics, Science and Technology Education. Cape Town, South Africa: SAARMSTE.

Modeling theory promotes evolution of student paradigms about the physical world through mediated learning of scientific theory and inquiry. Students are guided through learning (modeling) cycles to structure the content of any scientific theory around a few basic models through insightful, reflective, and collaborative inquiry. Each cycle is devoted to the progressive construction and deployment of a specific model and its conceptual building blocks in accordance with particular modeling schemata and following particular modeling schemes.   Full Text


Model-laden inquiry: A prescription for effective physics instruction. (2000). THEMES, 1 (4), 339-355.

Physics students often fail to transcend the realm of common sense and evolve into the realm of science following conventional instruction of lecture and demonstration. In contrast, practice shows that this evolution can be made possible through model-based, reflective inquiry. In such a process, students are empowered with scientific tools and habits to reconstruct every physics theory around a few basic models.   Full Text


Schematic concepts for schematic models of the real world: The Newtonian concept of force. (1998). Science Education, 82(2), 239-263.

A scientific concept can be defined explicitly with five schematic dimensions: domain, organization, quantification, expression and employment. Students’ cognitive evolution into the scientific realm can take different directions ranging from reinforcing existing concepts to constructing novel ones on completely new foundations. Such evolution is best achieved in student-centered, model-based instruction. The Newtonian concept of force is discussed for illustration, along with the results of tutoring two groups of Lebanese students to develop this concept in a schematic modeling approach.  Full Text


Interactive Model-Based Education: An Alternative to Outcomes-Based Education in Physics. (1998). South African Journal of Science, 94, 313-318.

South Africa has recently opted for Outcomes-based Education (OBE) in its primary and secondary school curricula. Interactive model-based education (IME) is an approach for teaching and learning science that is aligned in some respects with OBE, but that differs in others. Major tenets of OBE are first discussed and compared to those of IME. The effectiveness of IME in improving learners’ understanding of physics is then shown so as to present it as a viable alternative to OBE.   Full Text


Schematic modeling for meaningful learning of physics. (1996). Journal of Research in Science Teaching, 33(9), 1019-1041.

Models are at the core of scientific knowledge, and modeling is a major process for constructing and employing this knowledge. A model is defined by its composition and structure, and situated in a theory by its domain and organization. Modeling involves model selection, construction, validation, analysis and deployment. Two groups of Lebanese high school and college students participated in problem solving tutorials that followed a schematic modeling approach. Both groups improved significantly in problem solving performance, and course achievement of students in the college group was significantly better than that of their control peers.   Full Text


Teaching model construction for solving physics problems. (1994). Recherches Pédagogiques, 19, 5-17.

A dialectic teaching method is proposed that prescribes how to develop appropriate physico-mathematical models for solving physics problems. Secondary school and college students who were trained following this method showed a significant improvement in solving mechanics problems. Furthermore, the achievement in a university physics course of college trainees was significantly better than that of a control group.   Full Text
