Abstract
Mathematical reasoning is the ability of inductive and inferential reasoning with mathematical concepts that underlying cognitive variables play an important role in explaining it. The purpose of this study is to model the role of divided attention and working memory in mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence in fourth grade elementary students. This study is non-experimental (descriptive) and a type of correlational study in which data were analyzed by Path Analysis. The statistical population of the research included all male fourth-graders of the primary schools in District 4 of Qom from which 213 students were randomly selected by two-stage cluster sampling. The study used different measures and instruments including the Integrated Visual and Auditory Continuous Performance Test-Second Edition (IVA-2 CPT) for measuring different types of attention, the Working Memory Index of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), the Culture Fair Intelligence Test (CFIT), the knowing questions test and the mathematical reasoning questions test of TIMSS 2015. The findings of the study showed that all path coefficients are significant and appropriate model fit indices were obtained. The results indicate that working memory influenced by divided attention predicts mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence. The research helps to develop in mathematics learning and cognitive rehabilitation of mathematical disorders by identifying the role of important cognitive variables in mathematical reasoning.

Abstract
The objective of the present study was to compare the impact of two distinct educational approaches, namely the Montessori and robot-based methodologies, on students' executive functions. The research design was quasi-experimental, with two experimental groups and a post-test and follow-up. A total of 34 available female students from the second elementary grade were selected from the schools where Montessori classes were held. The students were free from physical or mental impairments and did not exhibit learning disorders. Each experimental group received one of the training methods in 12 sessions of 75-90 minutes. Following this, the post-test and follow-up were conducted using the Wisconsin tool to evaluate cognitive flexibility, the Stroop task to evaluate response inhibition, and the Cornoldi task to evaluate working memory. Multivariate mixed-variance analysis was employed to analyze the data. The findings of the study indicated a significant difference between the two educational approaches in enhancing students' executive functions (p<0.01). Additionally, the subscales of executive functions (as defined by Miyake, 2000) demonstrated significant differences, thereby corroborating the efficacy of the Montessori educational method in fostering cognitive flexibility and response inhibition. However, with regard to working memory, the robot-based educational method was found to be of greater importance. Due to the nature of the Montessori education method, which is based on fully targeted tools and activities, the above results are acceptable; Also, due to the sequence of programming in educational robots and the need to use previous information and pay attention to the previous stages of coding, the effectiveness of robot-based education is also acceptable.
