This research aimed to effect an adaptive navigation system according to the learning style in a multimedia environment on the development of problem solving skills of prep-school stage pupils in the science course, where the developmental research approach was used to lay the foundations, principles and criteria for designing an adaptive navigation system according to the Holistic and analytical learning style, then developing, using, and evaluating it, and the tools for research consisted in the scale of the Holistic and analytical learning style, and a test for problem solving skills, and the pre-post experimental design was relied upon for two equal groups, where the research sample was determined from (63) pupils from the second year of prep-school stage at Muhammad Issa Al-Alimi Preparatory School in Shama, This sample was divided into two groups, one of which is an experimental first and exposed to a navigation system. Adaptive according to the Holistic learning style and consists of (30) students, the other is a second experimental system and is exposed to an adaptive navigation system according to the analytical learning method (33) students Then, conducting a basic research experiment, applying appropriate statistical treatment methods, and several results were reached, the most important of which is that the mean scores of the two experimental groups in the post application of the problem solving skills differed by a statistically significant difference from the pre-application scores, as well as the absence of a significant difference Statistically among the mean scores of the first and second groups in problem solving skills in the dimensional application.
