The main intent of the current study was to investigate the effectiveness of the reciprocal-teaching strategy in learning outcomes and attitudes of Qassim-University students in Islamic culture. The study was conducted in Oqlat Al-Soqour Faculty of Sciences and Arts for paucity of research conducted in such a faculty, as well as for being the researcher's workplace which can offer him needed facilities. Statistical analyses of the data revealed that there were statistically significant differences between the mean scores of the experimental and control groups in the post administration of the learning-outcomes test as well as in the attitude scale in favour of the experimental. The magnitude effect was big which proved the effectiveness of the reciprocal-teaching strategy. [A bibliography is included.]
