This study investigated the impact of teaching physics via modeling on the acquisition of energy and momentum conservation concepts.

The sample consisted of 91 female students selected from 11th grade female students in two schools in Al-Dakhiliyah Governorate in Oman.

The experimental group (n = 45) was taught via the modeling method, and the control group (n = 46) was taught using a traditional method.

The study lasted six weeks during the second semester of the academic year 2013/2014.

A teacher guide for teaching by models was designed and validated by a group of experts.

To measure the acquisition of physics concepts, energy and momentum, an achievement test was used.

The test consisted of 20 multiple-choice questions.

Its reliability was measured by test-retest method (r = 0.79).

The results revealed a statistically significant difference (p < .05) between the means of the experimental and control groups in favor of the experimental group.

The study recommends that science teachers ought to use models and modeling in their teaching.

Workshops to train supervisors, in-service teachers and pre-service teachers in the construction and development of scientific models need to be conducted.
