The aim of this study was to investigate the predictive ability of the metacognitive thinking strategies and level of processing in problem solving skills among 10th grade students. The sample consisted of (236) female students from the city of Amman. To achieve the aim of the study, two scales were developed; one was developed to assess problem solving skills, the other was developed to assess metacognitive thinking strategies, whereas the scale of the level of processing developed by Biggs and his colleagues was used to assess level of processing. To answer the research questions, first, the coefficients of correlation between participants’ scores on problem-solving, metacognitive thinking strategies, deep processing, and shallow processing were calculated. Second, a simple step wise regression was performed to study the size of variance explained by the predictive variables. The results indicated positive relationship between problem solving skills and each of metacognitive thinking strategies, and deep processing, meanwhile there was negative relationship between problem solving skills and shallow processing, and the main finding indicated that metacognitive thinking strategies explain 44% of the total variation in problem solving skills. These results generally confirm that metacognitive strategies can predict performance in problem solving skills
