Authors: Mufassir Fadiel , Lestari Caecilia Citra
Published: September 2021

In 2018 the total revenue from the digital game market has reached 137.9 billion USD with mobile being the largest segment of the digital gaming market. The games downloaded on Google Play have several categories, one of which is the role-playing category. That's where the opportunity to follow a trend appears by making an Android game that has the roguelike genre, which is a subgenre of role-playing games. Most games with the roguelike genre don’t have a story or it has a linear one with no control over the emotions of the player character, so this game will be made with a branching narrative story structure which allows players to choose the storyline to make it more interesting. A branching narrative offers the player with important choices; every choice offers a unique outcome to a certain scenario even though the number of outcomes in the story is limited. The survey shows that the branching narrative in the game can increase the curiosity of the player to the story in the game, increase the desire of players to play the game again, and that the branching narrative is strong enough to increase the desire of players to make an In-App Purchase.

CONTEXT

Daily outdoor play is encouraged by the American Academy of Pediatrics. Existing evidence is unclear on the independent effect of nature exposures on child health.

OBJECTIVE

We systematically evaluated evidence regarding the relationship between nature contact and children’s health.

DATA SOURCES

The database search was conducted by using PubMed, Cumulative Index to Nursing and Allied Health Literature, PsychInfo, ERIC, Scopus, and Web of Science in February 2021.

STUDY SELECTION

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In all searches, the first element included nature terms; the second included child health outcome terms.

DATA EXTRACTION

Of the 10 940 studies identified, 296 were included. Study quality and risk of bias were assessed.

RESULTS

The strongest evidence for type of nature exposure was residential green space studies (n = 147, 50%). The strongest evidence for the beneficial health effects of nature was for physical activity (n = 108, 32%) and cognitive, behavioral, or mental health (n = 85, 25%). Physical activity was objectively measured in 55% of studies, and 41% of the cognitive, behavioral, or mental health studies were experimental in design.

LIMITATIONS

Types of nature exposures and health outcomes and behaviors were heterogenous. Risk of selection bias was moderate to high for all studies. Most studies were cross-sectional (n = 204, 69%), limiting our ability to assess causality.

CONCLUSIONS

Current literature supports a positive relationship between nature contact and children’s health, especially for physical activity and mental health, both public health priorities. The evidence supports pediatricians in advocating for equitable nature contact for children in places where they live, play, and learn.

Published: September 2021

In this study the individual profiles of seminal plasma proteins (SPP) in rams of three breeds – Merino, Pleven Blackhead and Ile de France - were analysed. The study was carried out with three rams at 3, 6 and 10 years of age, grown and fed under similar conditions. Eighteen ejaculates (6 ejaculates from each ram) were evaluated by Sperm Class Analyzer. The total SPP concentration was measured spectrophotometrically. The separation and characterisation of SPP was performed by HPLC and one dimensional polyacrylamide gel electrophoresis (SDS-PAGE). There were no significant differences between the characteristics of ejaculates and the main kinematic parameters of the sperm in the breeds studied. Chromatograms showed specific profiles with 9, 10 and 11 protein peaks for Merino, Pleven Blackhead and Ile de France breeds, respectively. The total SPP concentration was the highest in the Pleven Blackhead breed and the lowest in Ile de France breed. The major parts of SPP in the three breeds were identical. The seminal plasma of Merino breed contained proteins with molecular mass of 30.3 kDa, 15.7 kDa and 15.2 kDa that were not present in the other two breeds. In the Ile de France and Pleven Blackhead samples only, two proteins with molecular masses of 39.7 kDa and 21.1 kDa, were observed. In conclusion, the detection of specific proteins can be used as a biological marker for sheep breed identification.

Authors: SHOKOUHIAN Ali , OMIDI Heshmat
Published: September 2021

Seed priming has proved to be an effective method in imparting stress tolerance to plants using natural and/or synthetic compounds to treat the seeds before germination. The present study was designed to investigate the physiological mechanism of seed priming with ZnSO4 (osmopriming) and distilled water (hydropriming) on sugar beet genotypes (‘Shokofa’, ‘Sina’, ‘Paya’, ‘Turbata’, and ‘Aria’) germination indices, seedling growth parameters, and biochemical properties under salinity stress (0, 2, 5, and 12 dS/m NaCl). A significant reduction in germination percentage (33.23%), germination rate (77.2%), chlorophyll a, b, and total contents (43.9, 31.9, and 39.9%, respectively) while, a significant increase in radical, plumule, and seedling length (57.1, 44.4, and 51.2%, respectively), seedling vigour index (48.9%), superoxide dismutase activity (61.3%), proline (54.0%) and sugar (56.3%) contents were achieved at 12 dS/m NaCl in compared to the control treatment. Seed hydropriming and osmopriming caused significant improvements in photosynthetic pigments, antioxidant enzyme activity, and proline content reflected in high germination percentage and rate as well as seedling vigour index and reduced mean germination time under salinity. ‘Paya’ and ‘Aria’ genotypes had a superiority according to the germination percentage and seedling vigour index, respectively. The hydropriming of ‘Paya’ genotype resulted in the highest germination percentage (95%) under high level of salinity (12 dS/m) which 11.84% increase compared to the control treatment. Hydropriming of ‘Sina’ seeds showed the highest chlorophyll a and total, and carotenoids under non-stress conditions (22.89, 31.65, and 2116.6 µg/g FW). Also, hydropriming by increases chlorophyll b content led to the modulation of the negative effects of high salinity stress (12 dS/m). In conclusion, different seed priming treatments in sugar beet seeds improved the salinity tolerance by physiological characteristics nonetheless hydropriming was the most effective treatment to get higher germination indices in ‘Paya’ and ‘Aria’ genotypes.
Identification of SNPs in rice GPAT genes and in silico analysis of their functional impact on GPAT proteins
Authors: SAFDER Imran , SHAO Gaoneng , SHENG Zhonghua , HU Peisong , TANG Shaoqing
Published: September 2021

SNPs are the most common nucleotide variations in the genome. Functional SNPs in the coding region, known as nonsynonymous SNPs (nsSNPs), change amino acid residues and affect protein function. Identifying functional SNPs is an uphill task as it is difficult to correlate between variation and phenotypes in association studies. Computational in silico analysis provides an opportunity to understand the SNPs functional impact to proteins and facilitate experimental approaches in understanding the relationship between the phenotype and genotype. Advancement in sequencing technologies contributed to sequencing thousands of genomes. As a result, many public databases have been designed incorporating this sequenced data to explore nucleotide variations. In this study, we explored functional SNPs in the rice GPAT family (as a model plant gene family), using 3000 Rice Genome Sequencing Project data. We identified 1056 SNPs, among hundred rice varieties in 26 GPAT genes, and filtered 98 nsSNPs. We further investigated the structural and functional impact of these nsSNPs using various computational tools and shortlisted 13 SNPs having high damaging effects on protein structure. We found that rice GPAT genes can be influenced by nsSNPs and they might have a major effect on regulation and function of GPAT genes. This information will be useful to understand the possible relationships between genetic mutation and phenotypic variation, and their functional implication on rice GPAT proteins. The study will also provide a computational pathway to identify SNPs in other rice gene families.

Published: September 2021

Broccoli is highly tremendously as it is enriched with healthy promoting phytochemicals. This research was undertaken to study the feedback of broccoli to different concentrations of un-irradiated and irradiated (50 kGy of gamma rays) titanium dioxide nanoparticles (TiO2NPs). Un-irradiated and irradiated titanium dioxide characterization was accomplished by FT-IR, XRD, TGA, SEM and TEM. Foliar spray of titanium dioxide was applied to the broccoli in regards to the results of the characterizations. The growth traits; plant height, leaves No. per plant as well as stem diameter of plants and physical quality of heads were measured. Also, nutritional components of heads were determined. The results detailed that vegetative growth and physical quality of heads positively responded to foliar application of titanium dioxide compared to those obtained from control and 50 ppm from irradiated titanium dioxide (ITiO2NPs) gave the highest values of all traits. Regarding to nutritional components of heads, the efficiency of photosynthesis increased by using TiO2 (un-irradiated and irradiated) specially, 50 ppm ITiO2NPs. Application of Ti significantly increased the osmolytes concentrations such as proline, total free amino acids and soluble sugars as well as the extracts of heads sprayed with TiO2NPs concentrations displayed a prospective DPPH free radical scavenging action. Likewise, absorption of other nutrient elements and amino acids pool increased by spraying TiO2NPs. It was found that there are several phytochemical constituents identified by GC-MS that contribute to the biological activity of the methanol extract of broccoli heads that were affected by the use of TiO2NPs. It is clear that from above results, the using of ITiO2NPs specially; 50 ppm stimulated growth, resulting in improved quality of broccoli heads which is ultimately reflected in productivity.

Published: September 2021

Spatial genetic variation involves spatial genetic structure (SGS) and genetic diversity is important genetic features of plants. We first evaluated spatial genetic structure (SGS) and genetic diversity among four populations of Alsophila gigantea from Hainan Island, China, using inter-simple sequence repeat (ISSR) markers. Significant but weak FSGS was found in A. gigantea. High genetic diversity was identified at the species level and the population level. AMOVA analysis revealed a low level of genetic differentiation among the four populations with high gene flow. Mantel test showed no significant correlation between genetic distance and geographic distance. It was found that association between annual mean temperature and annual precipitation with FSGS. Combined with these spatial genetic variation, abundant precipitation and suitable temperature create a stable environment for A. gigantea in Hainan Island, which allows the fern to expand rapidly during the LGM. These results further emphasized the role of outcrossing, and history and environmental factors in the evolution of A. gigantea. This study also provided new insights on in local adaptation of A. gigantea to environmental fluctuations, and available genetic data to enhance the conservation for relict tree ferns.

Published: September 2021

CRISPR/Cas is a genome editing technique, permits accurate improvement of fiscally significant yield species by transgenic and non-transgenic strategies. We have reviewed CRISPR/Cas9 with or without DNA solution design in both maize as samples to redesign tolerance against dry season obstruction, improving seed’s oil contents production, and a gift of herbicide strength. Fundamentally, by exploiting the technologies of CRISPR/Cas9, development with late advances in plant tissue culture can be brought directly into monetarily significant genotypes. The various crop species are major agricultural products and play an indispensable role in sustaining human life. Over a long period, breeders strove to increase crop yield and improve quality through traditional breeding strategies. Today, many breeders have achieved remarkable results using modern molecular technologies. Recently, a new gene-editing system named the clustered regularly interspaced short palindromic repeats CRISPR/Cas9 technology has also improved crop quality. It has become the most popular tool for crop improvement due to its versatility. It has accelerated crop breeding progress by its precision in specific gene editing. This review summarizes the current application of CRISPR/Cas9 technology in crop quality improvement. It includes the modulation in appearance, palatability, nutritional components, and other preferred traits of various crops. Assortment created through such CRISPR/Cas9 engaged advanced raising procedures can be muddled from the regularly happening assortment and appropriately should be quickly open for commercialization.

Hydroxycinnamoyl-CoA: shikimate hydroxycinnamoyl transferase (HCT) is mainly associated with monolignol biosynthesis, a central precursor to producing guaiacyl and syringyl lignins in plants. However, the explicit regulatory mechanism of HCT-mediated monolignol biosynthesis in plants still remained unclear. Here, the genome-wide analysis of the HCT gene family in Carthamus tinctorius as a target for understanding growth, development, and stress-responsive mechanisms was investigated. A total of 82 CtHCT genes were identified and characterized. Most of the CtHCTs proteins demonstrated the presence of two common conserved domains, including HXXXD and DFGWG. In addition, the conserved structure of protein motifs, PPI network, cis-regulatory units, and gene structure analysis demonstrated several genetic determinants reflecting the wide range of functional diversity of CtHCT-encoding genes. The observed expression analysis of CtHCT genes in different flowering stages under normal conditions partially highlighted their putative roles in plant growth and development pathways. Moreover, CtHCT genes appeared to be associated with abiotic stress responses as validated by the expression profiling in various flowering phases under light irradiation and MeJA treatment. Altogether, these findings provide new insights into identifying crucial molecular targets associated with plant growth and development and present practical information for understanding abiotic stress-responsive mechanisms in plants.

ABSTRACT Objectives: to analyze hand hygiene determinants of informal caregivers in a hospital environment. Methods: qualitative study conducted with 55 caregivers at a university hospital in the Northeast of Brazil. A semi-structured instrument was used, adapted from Nola Pender's Health Promotion Model, from which the deductive categories were derived. Results: the general behavior included hand hygiene before meals and after using the bathroom. Sensitivity to the requirements for hand hygiene was observed, but the barriers and self-efficacy consisted of the availability of soap or alcohol-based hand sanitizers, the lack of knowledge on the importance of and forgetfulness of the practice. The reinforcement on the importance of the practice and being in a contaminated environment were influencers, and commitment, warnings, and training were indispensable. Conclusions: benefits related to protection from infections were seen as positive determinants for hand hygiene adherence. For non-adherence, factors such as lack of sanitizing supplies, ignorance towards the importance of the activity, and forgetfulness stood out.

Published: September 2021

Durante la pandemia de la COVID-19 a las tradicionales actividades científico-académicas, se sumaron en paralelo el cuidado de los hijos o de los familiares, mayor carga del trabajo doméstico, nuevos retos de educación virtual, incluso manejo de salud mental de colegas, estudiantes y asistentes de investigación. Aunque el virus SARS-CoV-2 no discrimina en género o raza en su contagio, varios estudios demuestran que la pandemia afecta de manera desproporcionada la productividad de la investigación hecha por las mujeres en la academia y ciencia, especialmente a las madres. Antes de la pandemia la perspectiva de género ya era un tema poco abordado en las políticas de ciencia, tecnología e innovación colombianas, por lo que es más que necesario discutir los desafíos que las mujeres científicas colombianas enfrentan como resultado de la pandemia en el país. A partir de la revisión crítica de la literatura disponible sobre los retos ampliados para las mujeres científicas debido a la pandemia, se presentan recomendaciones de posibles acciones y estrategias multisectoriales dirigidas a minimizar el impacto de la COVID-19 en las comunidades históricamente subrepresentadas en la academia y la ciencia en nuestro país. La evidencia ya existente sobre los efectos diferenciados de la pandemia debe generar reflexión sobre cómo apoyar al personal científico en Colombia, en especial a madres y cuidadores. Se requieren estrategias para identificar intervenciones durante y después de la pandemia que estén orientadas a responder equitativamente a los impactos desiguales entre géneros en la academia y la ciencia colombiana.

Published: September 2021

The deformation patterns and failure mechanisms of pressurised cavities at shallow depth are relevant to many geotechnical applications, including tunnelling and horizontal directional drilling. In this paper, an experimental study of a reduced-scale pressurised cavity under geostatic stress is presented, in order to measure the effect of cavity length, vertical stress and soil density on soil deformation and failure. X-ray computed tomography is used to acquire images of the system at key stages of the cavity inflation process. A closed-shaped failure region developed around the cavities, beyond which shear planes of elliptic paraboloid shape formed, extending from the bottom of the cavities all the way to the free surface. The plane-strain assumption did not hold beyond the central portion of the longest cavity tested (L = 6D). The volumetric strain and porosity changes inside the shear bands showed significant dilation in dense specimens, but contraction in loose specimens. The average orientation and the thickness of the shear bands were in agreement with those found in the literature for passive arching mechanisms (anchoring). The orientation of the principal strains around the cavity follows catenary shapes, similar to those displayed in active trapdoor mechanisms.

Authors:   The Tourism Sciences Society Of Korea, Choi Ji-Won , Kim Kyoung-Bae , Lee Hoon
Published: September 2021

Social media has become a place where travelers express their emotions and record travel experiences. However, there has been little research on sharing travel experiences on social media and happiness. The purpose of this study is to understand why people share travel experiences on social media and is to propose a conceptual framework of the relationship between sharing travel experiences on social media and happiness. A systematic quantitative literature review method was applied to explore research trends in sharing travel experiences on social media. Specifically, from the SCOPUS database, a total of 120 articles were extracted followed by the PRISMA checklist. Then, they were coded with several categories, such as publication, keywords, the research contexts, and variables, and were finally exported to a Microsoft Excel spreadsheet and analyzed. Results of the systematic qualitative litterateur review suggest that sharing travel experiences on social media positively influences travel satisfaction and enhances travelers’ self-esteem and happiness. Theoretically, this study developed a new theoretical framework on the relationship between sharing travel experience on social media and happiness. In particular, the framework indicates that even though individuals motivation of sharing travel expediences are different, they may experiences either Hedonia or Eudaimonia by doing so. Results of this study also imply that social media could make practical functions such as advertising travel destination and monitoring current and potential travelers' behaviors.
Evaluation of bio-coagulants for colour removal from dye synthetic wastewater: characterization, adsorption kinetics, and modelling approach
Authors: IA Obiora-Okafo  , OD Onukwuli  , NC Eli-Chukwu
Published: September 2021

Dye usage for industrial applications has been on the increase and these activities generate large amounts of dye-constituted wastewater that should be treated before environmental discharge or reuse. Various studies have shown the application of natural organic polymer (NOP) coagulants in dye removal from industrial wastewater. In this research, the coagulation performances of Vigna unguiculata (VU) and Telfairia occidentalis (TO) for colour removal from crystal Ponceau 6R dye synthetic wastewater was studied. The proximate compositions, structure, and surface morphologies of the coagulants were investigated using standard methods, i.e. Fourier-Transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). Colour removal was evaluated through the time-dependent decrease in particle concentration and thus growth of flocs. Effects of the process parameters, including pH, coagulant dosage, dye concentration (DC), settling time, and temperature were preliminarily tested and the best range experimentally determined. The optimal operating conditions established were pH 2, 800 mg∙L−1 coagulant dosage, 100 mg∙L−1 dye concentration, 300 min, and 303 K. The order of greatest removal was VUC > TOC with optimum efficiency of 93.5% and 90.7%, respectively. The values of K and α obtained for VUC and TOC were 8.09 x 10−4 L∙mg−1∙min−1, 1.7 and 9.89 x 10-4 L∙mg−1∙min−1, 1.6, respectively. Coagulation time, Tag, calculated and deduced from the particle distribution plot, showed a rapid coagulation process. Coagulation-adsorption kinetics indicated agreement with the pseudo-second-order model deducing that chemisorption is the rate-controlling step. It further indicates that particle adsorption on the polymer surfaces occurred mostly as a mono-molecular layer and according to the chemisorption mechanism. Cross-validation showed good prediction of the experimental data. The selected coagulants have the potential for application as efficient coagulants while also showing significant adsorption characteristics. The application of kinetics and modelling in separation processes involving particle transfer is especially required in wastewater treatment.

Properties of 0+ excited states, generated by the pair and quadrupole-quadrupole interactions in some isotopes of the rare-earth region, are studied. The excitation energies for 0+ states, E (0)- and E (2)-transitions, Rasmussen parameter X and cross sections for two nucleon transfer reactions are calculeted taking into account the mixing of excited states with different values. The contribution of mixing excited states underestimates the values of the calculated physical quantities.

The article is devoted to the development of the theory of nonequilibrium pressure and temperature fields in two-phase thermodynamic systems simulating natural oil and gas reservoirs. Such systems are classified as strongly dissipative, since the flow process is accompanied by the predominant action of internal friction forces. The studies carried out made it possible to significantly clarify the concept of thermodynamic processes and establish new physical laws governing the formation of temperature effects during fluid filtration in real porous media. It is shown that the maximum values of the temperature effect do not reach the value of the integral Joule - Thomson effect for any values of the parameters of the medium and liquid, and in real oil and gas reservoirs, temperature changes are several orders of magnitude smaller than those predicted on the basis of the equilibrium theory.

An experimental setup has been developed for studying magnetophoresis in a layer of a magnetic fluid several millimeters thick by the method of transmission and reflection of light. In the experiment, we used the region of a ring magnet changing in sign of the magnetic field. The clarification of the central portion of the magnetic fluid layer, which is observed for several days, is interpreted by the fact that the concentration of particles is redistributed due to the processes of magnetophoresis of microparticles and diffusion of nanoparticles in an inhomogeneous magnetic field.
La mediación en los proyectos pedagógicos: artistas-docentes como creadores y creadoras de relación desde las artes visuales
Authors: García-Huidobro Rosario , Montenegro Catalina
Published: September 2021

Este artículo, enmarcado en un proyecto de investigación financiado por FONDECYT, sobre las creaciones de los y las artistas-docentes en Chile, busca reflexionar acerca del nuevo hacer de los y las artistas educadoras como quienes promueven la mediación a través de sus propuestas de proyectos artísticos-pedagógicos. Para ello se sitúa a la mediación como un juego de relaciones que se da en el proceso de creación artística y que cuestiona la autoría de la obra, ya que promueve aspectos más vinculados a la escucha y las relaciones reflexivas entre los-as sujetos. Estas ideas se ejemplifican a través del proyecto “La cartografía de los aprendizajes amorosos: reconocimiento de autoridad femenina en los procesos de aprendizaje”, desarrollado en 2018 por una artista-docente en una escuela de Santiago de Chile. A través de la descripción y reflexión del proyecto se señalan cuatro ideas y aportes claves sobre estos tipos de proyectos. Primero es que muestran a la mediación como un lugar para el intercambio y el aprendizaje. Segundo, como una acción que es onto-epistemológica de los y las artistas-docentes contemporáneos. Tercero, la mediación se establece como una característica que los-as sitúa como los-as principales transformadores-as del cambio social desde las artes. Por último, la mediación en estos proyectos se sitúa como una acción política que promueve la subjetividad del estudiantado.

El presente artículo de investigación presenta parte de los resultados de un proyecto desarrollado por el Grupo de Investigación en Educación Científica Intercultural (Grupo IECI) del Instituto CeFIE de la Facultad de Ciencias Exactas y Naturales (FCEN) de la Universidad de Buenos Aires (UBA). Para su realización se intervino en algunas instituciones educativas a las que asisten estudiantes, mayoritariamente, del pueblo originario qom. Siendo parte de una investigación-acción sobre Educación Científica Intercultural (ECI), el objetivo específico de este trabajo fue encontrar puntos de contacto o vínculos entre conocimientos científicos y vernáculos, mediante una temática común; con este fin, se decidió trabajar con una comunidad qom de las provincias de Chaco y Formosa, Argentina. Asimismo, se diseñaron una serie de actividades didácticas exploratorias con la intención de develar la aparición de componentes culturales científicos y vernáculos sobre el agua, uno de los elementos más importantes para la vida humana. Esto se desarrolló al poner en diálogo tres relatos ancestrales donde intervinieron distintos seres de la cultura qom relacionados con el tópico elegido y los procesos que atraviesa el agua desde la mirada de la ciencia escolar. Parte de los objetivos generales de la investigación fueron la creación de materiales didácticos interculturales para generar conciencia de la diversidad cultural que integra nuestra sociedad.

Bu araştırmanın amacı, ortaokul altıncı sınıf öğrencilerinin kesirler konusunda sahip oldukları bilgiyi geri çağırırken nasıl bir süreç izlediklerinin belirlenmesidir. Araştırmaya 2019-2020 eğitim öğretim yılı Güz döneminde bir devlet okulunda altıncı sınıfta öğrenim gören on beş öğrenci katılmıştır. Araştırmanın verileri, öğrencilerin kesir kavramına ait kodlama ve geri getirme süreçlerini belirlemek amacıyla yapılan görev temelli görüşmeler kapsamında elde edilmiştir. Veriler içerik analizi yöntemiyle analiz edilmiştir. Bulgular “anahtar kelime yöntemi” ve “etkinlik yöntemi” olarak iki tema altında sınıflandırılmıştır. Elde edilen verilere göre, öğrencilerin bilgiyi geri getirme süreçleri farklılık göstermektedir. Öğrencilerin büyük bir kısmının sorular içindeki belirli kelime gruplarını, belirli ekleri veya öğretmenlerin işlemler hakkındaki söylemlerini ipucu olarak belleğine kodladığı ve bu sayede nasıl bir çözüm yolu seçeceğini belirlediği görülmüştür. Öte yandan sınıf içinde konuların öğretimi sırasında uygulanan etkinliklerin de öğrencilerin bilgiyi geri getirme sürecinde etkili olduğu tespit edilmiştir.

Bu araştırma ortaokul çağındaki öğrencilerinin matematiksel yetkinliklerinin çeşitli değişkenler açısından incelenmesi amacıyla yapılmıştır. Nicel araştırma yöntemine ve tarama araştırması desenine uygun olarak yürütülen araştırmanın verileri 2020-2021 eğitim öğretim yılının bahar döneminde Ankara ili merkez ilçelerinde bulunan ortaokullarda öğrenim gören 758 öğrenciden elde edilmiştir. Araştırmada dört boyut 34 maddeden oluşan “Ortaokul öğrencileri için matematiksel yetkinlik ölçeği” kullanılmıştır. Araştırmanın amacı doğrultusunda katılımcılardan elde edilen verilerin analizinde SPSS 23 paket programından faydalanılmıştır. Elde edilen veriler üzerinde betimsel istatistiklerden frekans, yüzde ve aritmetik ortalama ve bağımsız değişkenler arasındaki farklılıkların tespiti için t-testi ile Anova testlerinden yararlanılmıştır. Toplanan veriler üzerinden yapılan analizler sonucunda katılımcıların matematiksel yetkinliklerinin cinsiyet, matematik dersinden özel ders alma, matematik dersi için dershaneye/kursa gitme gibi değişkenlere göre farklılık göstermediği tespit edilirken, katılımcıların yer aldıkları sınıf değişkenine ve matematik dersi başarı notlarına göre matematiksel yetkinliklerinin anlamlı bir şekilde farklılaştığı saptanmıştır. Bu sonuçlardan yola çıkarak ortaokul kademesindeki öğrencilerin matematiksel yetkinliklerinin sınıf düzeylerine ve matematik dersi başarı notlarına göre neden farklılaştığını tespit etmeye yönelik farklı yöntem ve desenlerde tasarlanmış çalışmaların yapılması önerilmektedir.
