A1 السناني، محمد بن خليفة A2 أمبو سعيدي، عبد الله بن خميس بن علي AB The aim of the current study was to investigate the effectiveness of a proposed training program for grade 11 chemistry teachers to enhance their chemistry conceptual problem posing and solving skills. The sample was based on one group of sixteen chemistry teachers from various schools in the Dakhelyah governorate of the Sultanate of Oman. They were ponded training in a three-day workshop on how to pose and solve chemistry conceptual problems, by using the proposed strategies suggested by the researchers. Pre and post chemistry conceptual problem posing and solving tests were applied to the sample of the study designed by the researchers. The results demonstrated statistically significant differences at ( α= 0.05) on chemistry conceptual problem posing and solving skills, among chemistry teachers between pre and posttests in favor to post tests. Recommendations and suggestions were provided based on the findings.
