The aim of this research was to compare procrastination, learning strategies, and academic emotions between normal and learning-disabled students. The statistical population included normal and learning-disabled students of Qom city in the academic year 2019-1400, who had incorrect writing problems (learning disabilities in spelling). The statistical sample included 60 people (30 normal students and 30 students with learning disabilities). The method of the research was a causal-comparative approach. The tools used were the Takman's academic procrastination questionnaire (1991), Bofard's self-regulation questionnaire (1995), and the Pekruns' academic emotions questionnaire (2005). Data analysis was conducted using multivariate variance analysis test, and two independent samples t-test, using SPSS version 25 software. The results showed that the average academic procrastination of students with learning disabilities was higher than that of normal students. The mean of cognitive strategies, metacognitive strategies, pleasure, and pride of students with learning disabilities was lower than that of normal students. The average anxiety, shame, anger, frustration, and fatigue of students with learning disabilities was higher than that of normal students.

In this study, the possible pathways for the catalytic reaction of hydrogenation of alkenes using GaCl3.H2O catalyst in dichloromethane solvent with the presence of 1 and 4-cyclohexadiene were computationally performed using Density Functional Theory (DFT). The best way to undertake this reaction is to use an organic molecule as a hydride donor in the presence of a metal catalyst instead of working with hazardous hydrogen gas. The most commonly used metal in the field is platinum, whose high price has led scientists to look for a suitable replacement. The 13th group complexes, including gallium, can be good substitutes for platinum to catalyze this reaction. In this regard, three possible pathways were considered: two ways without the interference of the water molecule, including the catalyst binding to the hydride-donor species and the other one through the alkene binding to the catalyst, and the last pathway through the water molecule interference. All calculations have been conducted using Gaussian 2009 software and various computational methods and also, considering the solvent effects in accordance with the practical research that led to the elucidation of the mechanism of hydrogenation of alkenes.

The aim of this study was to investigate the degree of observance of Dubono's lateral thinking criteria in the intended curriculum of the second elementary school.

For this purpose, a quantitative approach was used using the survey method.

The results showed that only 25% of the identified criteria were observed in the textbook of experimental sciences of the second elementary school and despite the importance and possibility of teaching the rest of the criteria, compared to criteria such as 1. concept fan 2. random motivation 3. stimulation And movement 4. Product harvest 5. Motivation 6. Delayed judgment 7. Governing ideas and determinants 8. Random objects 9. Random word 10. Dealing with ideas has been neglected in compiling this book. The results showed that despite the importance of lateral thinking, unfortunately, not only the complete and appropriate presentation of criteria and indicators of lateral thinking in the textbook of experimental sciences of the second period has been neglected, but also in providing appropriate education and these criteria have been taught to students. Has not been. This has provided the ground for secondary school students to have a moderate level of performance in lateral thinking. It seems that the lack of attention to teaching the practices that enhance lateral thinking in the textbook of experimental sciences and the incomplete and non-practical presentation of these teachings, has provided the ground for the educational system and society with risky challenges in areas such as lack of creativity, formation of critical thinking and value thinking. To be.

Maurice Merleau-Ponty is a 20th century French phenomenologist. Merleau-Ponty's phenomenology is a phenomenology of sensory perception and he is trying to describe the essence of human sensory perception as an embodied subject. In this interdisciplinary study, we use Merleau-Ponty's pheno- menology to describe the sensory perception of contemporary human beings in cyberspace. In addition to establishing physical relationships with other people, the current embodied subject creates extensive virtual relationships with other subjects on a virtual platform on the Internet. According to Merleau-Ponty's phenomenology, the embodied subject in virtual relationships faces multiple relations in cyberspace and percept too many objects. The meanings that the embodied subject receives through his modern life in cyberspace from the objects and other embodied subjects in this space are ambiguous and opaque, despite their great extent.
