Preschool

The purpose of the present study was to construct and normalization the pre-school students' learning disability test. A researcher-made visual-spatial test consists of seven sections (symbolization, space status, visual distinction, visual argumentation, visual memory sequence, maze, and rotational form) its content validity is confirmed by psychology professors and then was performed on a sample of 206 preschool students. The questions were analyzed, and their validity, reliability and cut point were determined. This test has enough reliability. To determine the validity of construct and composing component of the tests, the main component by rotation in Varimax normalized method was used. In analysis of the factors of questions in spatial perception subtest, seven of which were namable. Conformity factor analysis was also used to determine the validity of factors: the conformity factor analysis confirmed that the structure of questionnaire had an acceptable fitness to the data. independent t-test demonstrated that there is a significant difference between average scores of the students with learning disability and normal. To investigate convergent validity, we used the checklist of learning disability that simultaneously was completed by the mothers. The results of Chi-Squared test demonstrated that there is a significant relationship between these two variables, the completed checklist by mothers and completed learning disability test by children.

Purpose: The aim of this research was comparison the development of ownership concept in preschool and elementary school children. Methodology: Present study in terms of purpose was applied and in terms of implementation was causal comparative. Research statistical population was all male and female children of preschool and elementary school of Pakdasht township in 2017-18 academic years. The research sample was 100 people (25 people in each grade) who were selected by random cluster sampling method. To collect data used from individually structured interview (31 questions) that the face and content validity of interview questions was confirmed by the educational sciences and psychology experts and its reliability was reported desirable by method of examiners. Data were analyzed by multivariate analysis of variance method in SPSS software version 19. Findings: The findings showed that there was a significant difference between the overall scores of the groups in the objective questions (P<0.05), but there was no significant difference between them in the descriptive questions (P>0.05). Conclusion: The results showed that preschool and first year elementary school children in compared to third and fifth year elementary school children do not have a good understanding and these children, unlike third and fifth year elementary school children, consider the first person who associates with the object as its owner.

Purpose : The present research was conducted with the aim of comparison of psychomotor skills and social adjustment in elementary students with and without preschool history. Methodology : This research in terms of time was cross-sectional, in terms of purpose was applied and in terms of implementation method was causal-comparative. The study population was the first to third grade students of Shiraz Kodak Afarin Educational Complex in the academic years of 2019-2020, which according to the Krejcie and Morgan table number of 144 people (90 people with preschool history and 54 people without preschool history) were selected as a sample by simple random sampling method. Data were collected by psychomotor skills test (Lincoln Oseretsky, 1950) and adaptive behaviors inventory (Lambert et al, 1974) and analyzed by independent t-test in the SPSS software. Finding : The results showed that elementary students with preschool history in compared to elementary students without preschool history significantly had a more favorable situation in terms of psychomotor skills (and all its components including touching, bending on the toe, harmonious tapping of the foots, standing on one foot, walk backwards and finger skills) and social adjustment (and all its components including violent behavior, antisocial behavior, rebellious behavior, unreliable behavior, avoidance, stereotyped behavior, inappropriate social behaviors, bad voice habits, bad or strange habits, hyperactivity tendency and psychological distress) (P<0.01). Conclusion : The results indicated the effect of preschool on psychomotor skills and social adjustment in elementary students. Therefore, to improve the characteristics of students is necessary to use a preschool education course.

Purpose: The present study aimed to describe the elements of the preschool curriculum with a problem-solving approach from the perspective of curriculum planning specialists and educational psychologists.  Methodology: This study was a qualitative study conducted in Tehran. The population consisted of curriculum specialists (n=200) and educational psychologists (n=238) who were selected using the purposive snowball sampling method, and 24 subjects were studied until reaching theoretical saturation. Semi-structured interviews were used to collect data. To analyze and interpret the data, the method of thematic analysis through coding was used. Findings: The findings indicated that from the perspective of curriculum planning specialists and educational psychologists, a problem-solving curriculum for preschoolers includes goals (cognitive, attitudinal, functional), content (organization, presentation methods), teaching methods (traditional methods, attention to learner's age, instructor's characteristics, and active methods), learning activities (individual, group), instructional materials (features and types of resources), space (physical characteristics of facilities), time (duration, attention to the child's preparedness and age), grouping (attention to responsibility, respect for others, attention to ethics considerations, attention to group homogeneity, nature of the problem, group heterogeneity, number of group members, gender, age, personal differences), and evaluation (of the program based on personal, procedural, quantitative, and descriptive differences).  Conclusion: Given the importance of the Comments, it can be continuously applied to and formulated for the preschool level to raise problem-solving skills in children and foster their abilities to understand and reflect on life in the future society.

Scientific thinking is a type of knowledge seeking involving intentional information seeking, including asking questions, testing hypotheses, making observations, recognizing patterns, and making inferences. The purpose of this research was designing a package of scientific thinking training and its ‘effect on problem-solving skill in preschool children. For this purpose, a study was designed in two steps. At first time, based on Kuhn theory and by reviewing and analysing available resources, the scientific thinking training package was designed. This teaching package includes discussions between the researchers and the child about stories with topics related to children's environment that they may not have encountered in everyday situations in the form of questions. At second step, in order to determine the effect of scientific thinking training on problem-solving, 30 children aged 5 to 6 (15 girls-15 boys) with a moderate score in Raven intelligence test was chosen from three primary schools. Subjects were trained individually in scientific thinking for 8 sessions. Data were analysed using repeated measures analysis of variance. Findings showed that teaching scientific thinking significantly improves problem solving skills (p <005) and this effect is stable over time. The results of this study show that preschool education and interaction with teacher is an opportunity to provide stimulus situations appropriate to children's abilities, and provide conditions for improving problem-solving.
