Morphological description of the glochidia of Buldowskia suifunica (Bivalvia: Unionidae).

Freshwater mussels of the genus Buldowskia (Bivalvia, Unionidae) are distributed from the Amur River basin in Russia and China southward to the Korean Peninsula and some Japanese islands. This work is an integrative morphological study of Buldowskia suifunica glochidia from locations in the Primorsky Territory, the Russian Far East. Glochidia of B. suifunica, taken from the same gill have asynchronous development. The external and internal morphology of its shell has been characterized. The morphology of its sensory system, within three stages of larval development (immature, intermediate and mature glochidia), consists of hair cells as well as nonhair cells. Their muscle system is composed of massive adductor and minor muscle bundles. The FMRFamid-ergic nervous system turned out to be a complex system includes basal cells (neurons), their neurites and anterior neurons. FMRFamide and tubulin was found in all neurons. Glochidia of B. suifunica have only four 5-HT-lir neurons. We concluded that B. suifunica glochidial nervous system differs from those of the larval systems of planktotrophic marine mollusks.

Neuromyths and knowledge about intellectual giftedness in a highly educated multilingual country.

Understanding brain functioning and intellectual giftedness can be challenging and give rise to various misconceptions. Nonetheless, there seems to be a widespread fascination and appetite for these subjects among the lay public and diverse professionals. The present study is the first to investigate general knowledge about the brain, neuromyths and knowledge about giftedness in a highly multilingual and educated country. Starting from and extending two seminal studies on neuromyths, several novel statements on intellectual giftedness have been included in order to explore knowledge and misconceptions concerning giftedness. Our sample (N = 200) was composed of Luxembourgish education professionals, including students in educational science and cognitive psychology, thus allowing to analyze responses in general and according to training and professional profiles. Specifically, Group 1 consisted of teachers and futures teachers (n = 152). Group 2 consisted of other education professionals and psychology students (n = 48). Despite the size and the unbalanced distribution of the sample, our findings indicate a good level of general knowledge about the brain and learning (71.3% of correct responses in average) which does, however, not preclude the presence of the typically observed original neuromyths. Thus, we replicate the classical finding that misconceptions on Learning Styles (70% of error rate) and the Multiple Intelligence Theory (71.5% of error rate) are the most represented, both in (future and in-service) teachers and other education professionals. Moreover, the present sample also revealed a high presence of misconceptions on intellectual giftedness. Limitations and future directions are discussed.

An insight into the fishery, biology and population dynamics of Auxis rochei (Risso, 1810) along the south-west coast of India

Auxis rochei is one of the coastal tunnies contributing substantially to the tuna landings inIndia, with an average (2014-2019) annual catch of 7210 t. Kerala stood first, with an annualaverage landing of 3176 t. The fishery comprised 14.5 - 39.6 cm fork length (FL) size groupswith a mean length of 27.64 cm and a major mode of 26 cm FL. The Length-weight (L-W)relationship of pooled fishes was expressed as W= 0.000003 L3.22 (r2= 0.91). The size at firstmaturity was estimated at 25.8 cm FL when the fish was 1.5 years old. The number of eggsper spawning ranged from 84,562 to 1,33,698 and the ova diameter ranged between 0.1and 0.6 mm, indicating asynchronous oocyte development with multiple spawning. Highergonadosomatic index (GSI) was recorded during April, May and June and coincided withthe minimum gastrosomatic index (GaSI). The recruitment pattern was bimodal, with variedintensity ranging from 0.79-17.89%. Growth was allometric and the von Bertalanffy growthequation derived was Lt=43.5(1-e-0.8(t+0.0212)). The growth performance index (ɸ) was 3.18 andthe longevity of the fish was estimated at 3.7 years. One-year-old plus fishes sustained thefishery (22 - 32 cm FL). Total mortality (Z), natural mortality (M) and fishing mortality (F)were estimated at 3.70, 1.40 and 2.30, respectively, with an exploitation rate (E) of 0.62and the exploitation ratio (U) of 0.60. Beverton and Holt yield per recruit (Y/R) and Biomassper recruit analysis indicated that the Emax was at 0.87, much higher than the present levelof exploitation, reflecting the sustainable fishery along the coast. Standing stock biomass(SSB) was estimated at 7215.7 t, and the spawning stock biomass formed 55.5% of the SSB.Thompson and Bell analysis indicated the MSY as 8125 t, at F-factor, 2.6. The biologicalreference points FCURR/FMSY (0.4) and BCURR/BMSY (1.5) were at safe levels, signifying the scopefor fishery enhancement.

A bioelectrical phase transition patterns the first vertebrate heartbeats.

A regular heartbeat is essential to vertebrate life. In the mature heart, this function is driven by an anatomically localized pacemaker. By contrast, pacemaking capability is broadly distributed in the early embryonic heart1-3, raising the question of how tissue-scale activity is first established and then maintained during embryonic development. The initial transition of the heart from silent to beating has never been characterized at the timescale of individual electrical events, and the structure in space and time of the early heartbeats remains poorly understood. Using all-optical electrophysiology, we captured the very first heartbeat of a zebrafish and analysed the development of cardiac excitability and conduction around this singular event. The first few beats appeared suddenly, had irregular interbeat intervals, propagated coherently across the primordial heart and emanated from loci that varied between animals and over time. The bioelectrical dynamics were well described by a noisy saddle-node on invariant circle bifurcation with action potential upstroke driven by CaV1.2. Our work shows how gradual and largely asynchronous development of single-cell bioelectrical properties produces a stereotyped and robust tissue-scale transition from quiescence to coordinated beating.

Dynamics of trace element enrichment in blue carbon ecosystems in relation to anthropogenic activities

Blue carbon ecosystems (BCEs), located at the land-sea interface, provide critical ecological services including the buffering of anthropogenic pollutants. Understanding the interactions between trace element (TE) loads in BCEs and socioeconomic development is imperative to informing management plans to address pollution issues. However, the identification of anthropogenic TE pollution in BCEs remains uncertain due to the complex geochemical and depositional processes and asynchronous socioeconomic development along continental coastlines. Here, priority-controlled TE (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) concentrations in the mangrove, saltmarsh and seagrass soils and plant tissues along the coastline of China were investigated while taking bare flat and upland soils as corresponding references. We demonstrate that blue carbon (BC) soils accumulated markedly higher concentrations of anthropogenic TEs than the reference soils, mainly due to the effective trapping of fine-grained particles and higher binding capacities. We identify the time course of TE changes over the last 100 years which shows increasing anthropogenic TE accumulation resulting from military activities (1930–1950) and the growth of industrial and agricultural activities (1950–1980), then reaching a maximum after national economic reform (1980–2000). Since the 2000s, decreases in TE discharges driven by socioeconomic reform and strengthened environmental regulations have led to a widespread reversal of anthropogenic TE concentrations in BC soils. Based on the current TE flux we estimate that BCEs can filter over 27.3–100 % of the TEs emitted in industrial wastewaters from Chinese coastal provinces annually. However, the uptake of these TEs by plants can be substantially reduced through various mechanisms offered by edaphic properties such as organic carbon, clay, and sulfur contents. Therefore, enhancing TE filtering while preventing TEs from entering food webs through the conservation and restoration of BCEs will greatly aid in achieving the sustainable development goal of the coastal zone under intensified anthropogenic activities.

Exploring and developing diverse potentials and abilities – new perspectives

This article presents novel approaches to exploring and developing children’s diverse potentials and abilities. Traditionally, potential has been understood as an individual’s innate endowment, primarily pertaining to intelligence, facilitating achievement. However, new perspectives encompass a broader spectrum of factors, including psychosocial aspects. This article examines two concepts. The first one is the Theory of Positive Disintegration, which focuses on the personal, emotional, and moral development of individuals. According to this theory, a strong developmental potential and its content play a crucial role in the development of personality and abilities. Gifted individuals exhibit characteristics such as heightened intensity of experiences and sensations, as well as asynchronous development. Education should embrace the unique and individualized growth of gifted individuals, with the aim of facilitating their development towards higher values and a complete personality. The second concept under examination is the Talent Development Megamodel, which focuses on domain-specific abilities. Within this framework, distinct trajectories of talent development are delineated based on an individual’s domain-specific ability and potential associated with abilities and psychosocial skills. The objective of education within the Megamodel is to foster achievements and ultimately exceptional accomplishments among the gifted.

Historical and Pedagogical Aspect of the Development of the Academic Talent of Students in Abroad Theory and Practice

This article is devoted to the one of the aspects of the students’ academic giftedness development in foreign theory and practice, which related to the history of pedagogy. The purpose of the article is to analyze the historical and pedagogical aspect of the development of academic giftedness of students in foreign theory and practice. The following used research methods were decisive as analysis and generalization of scientific and methodical sources, synthesis of the obtained data. Results. Academically gifted children have been found to have many needs that cannot be met by the standard education system. Therefore, in most educational institutions in Europe and the USA, programs for working with academically gifted children were designed and, in connection with this, the professional training programs for teachers were seriously changed and supplemented. An important role in the development of professional training of teachers who work with gifted and talented children is played by international organizations that research giftedness. Accumulated domestic and foreign experience on this problem shows the relevance of further development of theoretical foundations and practical ways of developing the academically gifted children education system. Conclusions. The peculiarities of the development of the education system for academically gifted children in the USA have been identifies by the author of the article as following: the deepening of profile and level differentiation of education; wide use of internal differentiation methods; the variability of forms of individualization of education; increase in the number of special educational institutions, departments and streams; the use of pedagogical mentoring programs. The specific peculiarities of the education content and methods of teaching gifted children, which consist in the application of accelerated learning and courses of «expansion» and «enrichment» of the program; increasing the role of effective teaching methods, modern technical means in the development of children's intellectual abilities. The author of the article concludes that for the successful intellectual development of children, as long-term practice shows, it is not enough to have a well-organized, systematic, intense general educational work in an educational institution, a necessary condition for this is the use of scientific concepts and methods for the problem of identifying and developing giftedness.

Sex differences in tech tilt and academic tilt in adolescence: Processing speed mediates age-tilt relations

Tilt refers to a pattern of specific abilities and is based on within subject differences in two abilities (e.g., technical and academic), producing relative strength in one ability (technical) and relative weakness in another ability (academic). This study examined sex differences in the development of tilt in adolescence (13- to 17-years) using the National Longitudinal Survey of Youth (N = 6969), a representative sample of adolescents in the United States. Tilt was based on within subject differences in technical (mechanical, electrical, automotive) and academic abilities (math or verbal) on the Armed Services Vocational Aptitude Battery. The differences produced tech tilt (technical > academic) and academic tilt (academic > technical). Consistent with investment theories and sex differences in technical preferences, males showed increases in tech tilt over time, whereas females showed increases in academic tilt over time, with sex differences in tilt increasing with age. In addition, processing speed and general intelligence (g) mediated most age-tilt relations, with age-tech tilt relations generally being stronger for males. The stronger age-tech tilt relations for males support investment theories and sex differences in vocational interests, which assume that stronger technical interests in males accelerate increases in tech tilt over time. The mediating effects of speed and g are consistent with cascade theories, which assume that age-related increases in speed boost g, which in turn boosts tilt. Future research should examine factors that influence sex differences in the development of tilt, including vocational interests (e.g., technical and academic), developmental period (e.g., later adulthood), and exceptional ability (e.g., intellectual giftedness).

Exo-erythrocytic development of Leucocytozoon parasites (Haemosporida, Leucocytozoidae) in song thrushes Turdus philomelos

Leucocytozoon parasites (Haemosporida, Leucocytozoidae) are haemosporidians whose diversity, exo-erythrocytic development and potential vectors are the least studied. The knowledge about their exo-erythrocytic development and pathogenicity is fragmentary, resulting in an incomplete comprehension of the impact of these parasites on avian hosts. For a long time, Leucocytozoon infections were considered benign to wild birds, even though they were virulent in poultry and responsible for some wild bird population declines. This study aimed to investigate the presence of Leucocytozoon species exo-erythrocytic stages in song thrushes Turdus philomelos using conventional histological techniques (sections stained by H&E) and chromogenic in situ hybridization (CISH). Tissues from ten birds (seven naturally infected and three opportunistic samplings) were examined using both methods. Parasite lineages were identified from blood samples using PCR-based techniques. Leucocytozoon species meronts were found in five individuals (in four birds using H&E staining protocol, and in three in CISH-treated histological sections). Meronts were found mainly in the kidneys, but some meronts were also present in the lungs. It was possible to observe different maturation stages of meronts in the same bird individual, indicating an asynchronous development. Cytomeres were readily visible in developing meronts. One megalomeront-like structure was present close to a blood vessel in the heart. It was covered with a prominent capsular-like wall. No inflammatory reaction or necrosis was seen in the tissues surrounding the meronts or the megalomeront-like structure. We could confirm the transmission of three Leucocytozoon lineages (lTUPHI14, lSTUR1 and lTUPHI13) in Europe, and add evidence of the transmission of two Plasmodium lineages, including Plasmodium circumflexum (pTURDUS1), and Haemoproteus asymmetricus (hTUPHI01). We call for further research to better understand Leucocytozoon parasite exo-erythrocytic development.

Knowledge about COVID-19 between Children and Adolescents with and without High Intellectual Abilities.

Among the characteristics within people with high intellectual abilities, some that stand out are a better handling of information, asynchronous development, high awareness, and sensibility. Therefore, our goal was to learn if, due to these characteristics, the children and adolescents with high intellectual abilities have a better understanding and comprehension about COVID-19 compared to those with average intellectual abilities. A qualitative study was conducted at the beginning of the lockdown with 649 children with and without high intellectual abilities. An online questionnaire was used and three open questions were analyzed with the ALCESTE software. The results showed that both groups had a similar handling of the information regarding COVID-19. Despite this, in the high ability group there is a greater social concern, which coincides with some characteristics associated with a more developed moral conscience. The results are then discussed in terms of the importance of designing actions that allow us to adequately follow the control and intervention strategies, as well as to propose improvements in the communication of relevant information before diverse crises to which the child population may be exposed.

Asynchronous development of memory integration and differentiation influences temporal memory organization.

Adults remember items with shared contexts as occurring closer in time to one another than those associated with different contexts, even when their objective temporal distance is fixed. Such temporal memory biases are thought to reflect within-event integration and between-event differentiation processes that organize events according to their contextual similarities and differences, respectively. Within-event integration and between-event differentiation are hypothesized to differentially rely on binding and control processes, which may develop at different ages. To test this hypothesis, 5- to 12-year-olds and adults (N=134) studied quartets of image pairs that contained either the same scene (same-context) or different scenes (different-context). Participants remembered same-context items as occurring closer in time by older childhood (7-9 years), whereas different-context items were remembered as occurring farther apart by early adolescence (10-12 years). The differential emergence of these temporal memory biases suggests within-event integration and between-event differentiation emerge at different ages. RESEARCH HIGHLIGHTS: Children are less likely than adults to use contextual information (e.g., location) to organize their continuous experience in memory, as indicated by temporal memory biases. Biases reflecting within-event integration (i.e., remembering elements with a shared context as occurring closer together in time) emerged in late childhood. Biases reflecting between-event differentiation (i.e., remembering elements from different contexts as occurring farther apart in time) emerged in early adolescence. The differential emergence of biases reflecting within-event integration and between-event differentiation suggests they are distinct, yet complementary, processes that support developmental improvements in event memory organization.

Climate Competencies of Finnish Gifted and Average-Ability High School Students

In the face of global issues such as climate change, the world needs action competent, transformationally gifted citizens, who are willing to step up and take responsibility for a better future. However, empirical evidence on what supports the development of transformational giftedness is limited. Furthermore, the relationship between academic giftedness and transformational giftedness has not been clearly pronounced. The purpose of this study is to address this research gap by examining students’ climate competencies. A total of 1703 students from five Finnish high schools (grades 10–12) participated in this study. Using a questionnaire, students’ climate change knowledge, values, willingness to take action, sense of responsibility, environmental concern, and perceptions on how climate change issues are dealt with in school were examined. Four of the schools were general education high schools, while one was for students formally identified as gifted students. The findings indicate that academically gifted students in both general education schools and the gifted school show more climate competencies than average-ability students. Furthermore, gifted students that attended the school for gifted students show more climate competencies than the gifted students from general education schools. Based on the findings, the paper discusses how the development of transformational giftedness can be better supported in education.

Reproductive traits, dynamics of oogenesis and embryonic developments in the deep-sea shrimp Plesionika semilaevis from the southeastern Arabian sea

Reproductive traits are a crucial biological indicator of a population's resistance to anthropogenic and environmental pressures. The reproductive biology of Plesionika species from temperate and sub-tropical regions is relatively well known. However, a knowledge gap exists regarding the species' reproduction and life strategies in tropical waters like the Indian Ocean. This paper covers the reproductive period, ovarian and embryonic development, embryo size, brood size and size at sexual maturity of Plesionika semilaevis, a commercially important species from the tropical waters of the southeastern Arabian Sea. Histological analysis revealed asynchronous oocyte development with multiple oocyte stages present in each ovary sample, although with varying proportions. Maturation of the ovary was seen during the embryo incubation phase, which indicates that females are able to spawn several times during a reproductive cycle. A total of 1802 females of P. semilaevis were examined and sorted into ovigerous and non-ovigerous stages, and the embryos were divided into four stages of development. Although ovigerous females were present in every month's samples, the main reproductive season is from November to February, as evidenced by the larger percentage of ovigerous females during this time. Based on the percentage of embryos in various stages, the spawning and hatching periods were estimated to be December to February and March to May, respectively. Embryo size increased with the developmental stage (p = 0) but was independent of body size (p > 0.05). A positive correlation was observed between brood size and female body size in all four stages of embryo development but, as the embryos developed a significant decrease in brood size was noticed. Based on the size at which 50% of the females had matured ovaries and 50% were ovigerous, the size at sexual maturity, CL50ov and CL50em, was calculated to be 15.51 mm and 15.07 mm in carapace length, respectively. The brood size ranged from 2093 to 12887 embryos with a mean size of 0.51 × 0.40 mm following spawning and 0.66 × 0.50 mm prior to hatching.

Non-Cognitive Specificities of Intellectually Gifted Children and Adolescents: A Systematic Review of the Literature.

For several years, there was a growing interest in intellectual giftedness and in particular in the non-cognitive specificities of gifted individuals. This topic attracted much public attention and sometimes led to contradictions with the scientific literature. The current review synthesizes a broad set of results related to non-cognitive specificities of intellectual gifted in children and adolescents. This synthesis of scientific research on giftedness and its associated non-cognitive features does not support the conclusion that there is a stable profile across gifted individuals that would consistently separate them from non-gifted individuals. A few specificities in some areas are noted, but they are not necessarily being systematic. These specificities often turn out to be in favor of gifted youth, contrary to the view sometimes defended in the general public that gifted individuals suffer from major everyday difficulties. Finally, methodological issues are listed regarding the designs of existing studies, with recommendations for future research in the field.

Determining Sexual Development and Size at Sexual Maturity of Sardinella tawilis and its Implications on Management

Reproductive biology is important in formulating management interventions for fish stocks. Limits on catch size are established based on the identified size at first sexual maturity of the target fish species, which can be accurately determined through histological analysis of gonads. The study investigated the reproductive characteristics of the endangered Sardinella tawilis and determined the size at first sexual maturity based on histological analysis. Between 2017 and 2018, 312 fish samples with different lengths were collected in Taal Lake's northern and southern basins. The length-weight relationship of S. tawilis shows that the species exhibits negative allometric growth. Female S. tawilis, characterized by larger sizes, are significantly more abundant in our catches than male individuals (mean sex ratio p<0.05) and exhibit an asynchronous oocyte development. Histological analysis of gonads showed that the size at sexual maturity for both male and female S. tawilis were at 75 to 79 mm FL, which was smaller than the reported size at sexual maturity based on morphological analysis. Smaller average and maximum lengths, as well as the size at first sexual maturity, could suggest that S. tawilis has experienced growth overfishing and a slowly degrading lake environment through time. Results highlighted the importance of ensuring that immature S. tawilis can enter sexual maturity and contribute to the population through reproduction. It is also highly recommended that the size of S. tawilis to be targeted by fisheries are individuals above 100 mm FL, which exhibited the highest proportion of spawning capable individuals.

"Mom, I want to learn English" - a developmentally asynchronous, linguistically gifted 1st grade pupil in the English language education process

The article presents the problem of functioning of a language-gifted pupil in the 1st grade of primary school during English lessons, showing features of asynchronous development. The goal of the research was to indicate to what extent the implemented core curriculum and teaching methods meet the needs of a 7-year-old boy in the experiences of the child and his parents. In the scientific inquiry, an individual case study was used with the use of a semi-directed, problem-focused interview. The results of the conducted research haveshown that the curriculum and educational methods do not enable individual development of the child in the language area while arousing reluctance to participate in the education process. which results in the appearance of emotional difficulties.The conducted research encourages discussion on the need for changes in the organization of the education process of talented, developmentally asynchronous students in various areas of education and to search for practical solutions.

Features of the microscopic structure of the intestinal wall in females of the ixodic tick of the genus Dermacentor during the feeding period

Ixodic ticks of the genus Dermacentor are parasitomorphic ticks that are carriers of a number of dangerous zooanthropozonoses, have a wide distribution. The intestine of an adult contains several types of cells: digesting, secretory, reserve and yolk cells. Digestive cells of types 1 and 2 are involved in the process of intracellular digestion and are the main components of the wall of the middle intestine. After insemination, yolk cells begin to form in the intestine, regulating the development of oocytes. The research was carried out on the basis of the Department of Parasitology and Veterinary and Sanitary Examination, Anatomy and Pathanatomy named after Prof. S. N. Nikolsky and at the Scientific Diagnostic and Therapeutic Veterinary Center of the Stavropol State Agrarian University, as well as on the basis of veterinary clinics of IP Zaichenko "Veterinary Center named after Pirogova". The object of the study was ixode mites, the material for the study was the digestive system of females, in particular the middle part of the intestine. Macroscopic examination of the nourished females of the Dermacentor tick helped to reveal that the intestine is an unpaired tubular organ divided into three sections: the esophagus, the sac-like meatus and the small intestine. With the arrival of blood, the intestine expands, as a result of which reserve cells begin to grow and differentiate into primary digestive ones. By the time egg laying begins, digestive cells of type I degenerate and are replaced by digestive cells of type II, differentiated from reserve cells. In nourished females, with an active process of vitellogenesis, the presence of specialized yolk cells is noted. Thus, with the beginning of the feeding period in ixodic mites, an increase in the intestine occurs due to the asynchronous development of digestive cells of type I and II. During digestion, secretory cells are focally exfoliated into the intestinal cavity filled with the host's blood, which characterizes the acceleration of the process of erythrocyte hemolysis. In the final phase of digestion, and the beginning of the vitellogenesis process, yolk cells are formed that regulate the development of oocytes.

Genome-wide identification and comparative analysis of DNA methyltransferase and demethylase gene families in two ploidy Cyclocarya paliurus and their potential function in heterodichogamy

BackgroundDNA methylation is one of the most abundant epigenetic modifications, which plays important roles in flower development, sex differentiation, and regulation of flowering time. Its pattern is affected by cytosine-5 DNA methyltransferase (C5-MTase) and DNA demethylase (dMTase). At present, there are no reports on C5-MTase and dMTase genes in heterodichogamous Cyclocarya paliurus.ResultsIn this study, 6 CpC5-MTase and 3 CpdMTase genes were identified in diploid (2n = 2 × = 32) C. paliurus, while 20 CpC5-MTase and 13 CpdMTase genes were identified in autotetraploid (2n = 4 × = 64). 80% of identified genes maintained relatively fixed positions on chromosomes during polyploidization. In addition, we found that some DRM subfamily members didn’t contain the UBA domain. The transcript abundance of CpC5-MTase and CpdMTase in male and female flowers of two morphs (protandry and protogyny) from diploidy was analyzed. Results showed that all genes were significantly up-regulated at the stage of floral bud break (S2), but significantly down-regulated at the stage of flower maturation (S4). At S2, some CpC5-MTase genes showed higher expression levels in PG-M than in PG-F, whereas some CpdMTase genes showed higher expression levels in PA-M than in PA-F. In addition, these genes were significantly associated with gibberellin synthesis-related genes (e.g. DELLA and GID1), suggesting that DNA methylation may play a role in the asynchronous floral development process through gibberellin signal.ConclusionsThese results broaden our understanding of the CpC5-MTase and CpdMTase genes in diploid and autotetraploid C. paliurus, and provide a novel insight into regulatory mechanisms of DNA methylation in heterodichogamy.

Özel Yetenekli Öğrencilerin Belirlenmesinde Sınıf Öğretmenlerin Rolü

In order for a country to advance in science and art and to shape its own future, it is necessary to raise well-informed, intellectual and enlightened individuals with critical thinking and problem-solving skills. In this context, gifted students are the most important potential of the country in terms of human resources. Gifted students, who can learn faster than their age group and have a higher intelligence, will undoubtedly be the artists and scientists of the future when they receive an education appropriate to their level. These students should be identified by their classroom teachers during their primary school education and directed to Guidance Research Centers in order to maximize their potential in areas such as intelligence, creativity and artistic talent, and then they should be provided to take the Science and Art Centers Student Selection Examination. Key Words: Education, Classroom Teacher, Gifted Children
