AU - محمود، حسن فاروق AU - السعدون، سرحان بن حمدان AB - The current research aimed to reveal the effectiveness of a proposed program based on participatory training across the web in developing mathematical representations among mathematics teachers at the primary level. To achieve the goals of the research, the researchers prepared the research tools, which were: a survey questionnaire to determine the patterns of mathematical representations and an achievement test to measure the cognitive aspects related to the performance of mathematics teachers for mathematical representations, and a note card that measures the performance of mathematics teachers when teaching with mathematical representations. The results of the research revealed the presence of statistically significant differences between the mean scores of the teachers of the experimental group in the pre and post measurements on the achievement test of the cognitive aspects related to the performance of mathematics teachers for mathematical representations, as well as the presence of statistically significant differences between the mean scores of the teachers of the experimental group in the pre and post measurements On a note card for the performance of mathematics teachers at the primary level when teaching with mathematical representations. The results revealed the effectiveness of the program based on participatory training across the web in developing mathematical representations for elementary mathematics teachers.
