The purpose of this study is to develop an inquisitive learning strategy based on a version of the scientific model with a reinforced co-construction factor. This strategy will be applied to the acquisition of chemical change and physical change concepts to better understand the modalities of learner model-building and social interactions. A modeling acquisition strategy was developed, based on a modified and supplemented version of Halloun’s Model Learning Cycle. The developed modeling acquisition strategy was introduced into sessions at the N Education Center for Gifted Children. Class observation, recording and activity analysis sheet analysis formed the base for analyses of learner model-building processes and interaction modalities, and a survey was performed to study learner perceptions of the modeling acquisition strategy. The study showed that the modeling acquisition strategy was effective in acquisition of non-visual phenomena and abstract scientific concepts. Learners were found to perform model-building based on their own subjective rationale, and to explain observed phenomena using the so-built models. Also, differences in model selection and modification were observed according to differences in group interaction modalities. Analysis of models suggested by learners is expected to allow for the understanding of learner reasoning systems, which will in turn contribute valuable information to deciding the direction of scientific acquisition. In order for effective modeling acquisition to take place, a cooperative classroom atmosphere must be created, and conditions need be made to allow for all group members to actively participate in class sessions.
