Abstract
This research aimed at measuring the impact of a web-based training program in developing professional attitudes and literacy levels about the STEM integration approach among middle school science teachers. The research utilized the experimental approach of one group design with pre-and post-measurement. The participants comprised (16) middle school teachers in Wadi Al-Dawasir, Riyadh, Saudi Arabia. For data collection, the professional attitudes towards the STEM scale and the STEM literacy level scale were applied. Results demonstrated that there were statistically significant differences at (a=0.05) between the mean scores of the experimental group pre-and post-measurements in the scale of professional attitudes towards STEM in favor of the post-measurement and statistically significant differences at (a=0.05) between the mean scores of the experimental group pre-and post-measurements in the STEM literacy level scale in favor of the post-measurement. Recommendations and suggestions were presented.
