Published: September 2023

Background: Pseudomonas aeruginosa is an important environmental, opportunistic, and nosocomial pathogen with a significant threat to public health. Combination therapy has many advantages due to the simultaneous action of two drugs on two separate cellular targets. In the present study, the effect of the combination of doxycycline and natural products against planktonic cells, biofilm, and virulence factors of P. aeruginosa was evaluated. Methods: To perform this work, minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of doxycycline and natural products were determined by broth microdilution method. The microtiter plate assay method was used to determine the minimal biofilm inhibitory concentration (MBIC) and the minimum biofilm eradication concentration (MBEC). The effect of doxycycline and natural products against pyocyanin, swarming motility, and swimming motility was evaluated. The checkerboard method was used to evaluate the effect of the combination of doxycycline with natural products against planktonic and biofilm cells. Results: The MIC of doxycycline ranges between 2 µg/mL and 128 µg/mL with an average of 35.89 µg/mL. Sinapic acid shows the best inhibitory activity against planktonic cells with an average MIC of 27.79 µg/mL. At the sub-inhibitory concentrations, the pyocyanin production, swarming motility, and swimming motility decrease. Out of the six combinations tested, the combination formed by doxycycline and sinapic acid exhibited synergistic activity for the prevention of biofilm formation with a 7-fold reduction in MBIC of doxycycline. Conclusion: This study revealed that the doxycycline and sinapic acid combination could be considered as a promising candidate for the development of therapy against P. aeruginosa infections.
PPP1R14B is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: September 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that protein phosphatase 1 regulatory inhibitor subunit 14B, encoded by PPP1R14B, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. PPP1R14B mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of PPP1R14B in primary tumors was correlated with overall, distant metastasis-free and recurrence-free survival. Modulation of PPP1R14B expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Authors: Nadeem Muhammad
Published: September 2023

In the rapidly evolving realm of higher education, the integration of effective quality assurance mechanisms has become imperative for institutions to ensure educational excellence and meet global standards. Central to this endeavor is the role of leadership, which intricately shapes the implementation and success of quality assurance initiatives. This paper delves into the intricate relationship between leadership and quality assurance in higher education institutions, aiming to uncover the nuanced interplay between leadership styles and quality enhancement efforts. Through a comprehensive literature review and conceptual analysis, a robust framework emerges that illustrates how diverse leadership styles—transformational, transactional, and distributed—intersect with quality assurance mechanisms, subsequently influencing educational quality. The practical implications of the framework underscore the importance of tailored leadership development programs, cultural alignment, and strategic decision-making for effective quality assurance. Furthermore, this paper sets a visionary trajectory by delineating promising avenues for future research, including empirical validation, cross-cultural comparisons, exploration of long-term effects, stakeholder engagement, and adaptation to technological advancements. By bridging theory and practice, this paper not only enriches the discourse on leadership and quality assurance but also offers a navigational guide for educators, administrators, policymakers, and researchers striving to elevate the standards of higher education.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that glutaredoxin 2, encoded by GLRX2, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. GLRX2 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of GLRX2 in primary tumors was correlated with overall, distant metastasis-free and recurrence-free survival. Modulation of GLRX2 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.
Effects on Target Geology
Authors: Rae Auriol , Bray Veronica
Published: September 2023

The process of impact crater formation can fundamentally change the nature of target materials, creating products that can be observed from planetary-scale geophysics all the way down to mineral microstructure. Impact-generated shock waves can vaporise, melt, and permanently deform the materials they pass through. Large quantities of the target are damaged and displaced, ejecting material outside of the crater and redistributing various shock products and brecciated material within the crater. The aim of this chapter is to describe the changes that occur within target materials and the physical processes that produce them during an impact event.
A Tutorial on Unidimensional Unfolding: From Automatic Item Generation to Insightful Inferences
Authors: Franco Víthor Rosa , de Francisco Carvalho Lucas
Published: September 2023

Unfolding theory maps individuals and stimuli into a common latent space, reflecting preferences through proximity. Unlike traditional psychometric methods, unfolding models are complex and computationally intensive, leading to their underuse despite their potential for nuanced insights. This study presents a tutorial on unidimensional unfolding, using ChatGPT to create items and providing R functions for analysis. Structured sequentially, we first describe what AIG is, highlighting the possible improvements allowed by large language models in general. Subsequently, the unidimensional unfolding theory, synonymous with the Coombs system, is introduced as the foundation for our AIG procedure. The following section is a description of our rationale on the approach to training ChatGPT in the creation of items via the binary tree structure, concurrently instructing the reader on how to analyze the data. We then present a practical case study focusing on the measurement of attention-seeking tendencies, with a comprehensive presentation and commentary on the necessary R code. The paper concludes with reflections on future directions for research endeavors.

Published: September 2023

Trotz jüngster gesetzlicher Änderungen in Richtung einer stärkeren Inklusion von LGBTIQ+ Personen (d.h. lesbischen, schwulen, bisexuellen, trans, intergeschlechtlichen und queeren Personen) sind LGBTIQ+ Jugendliche in der Schweiz immer noch mit Ungleichheiten, Ablehnung und Diskriminierung in verschiedenen Bereichen konfrontiert. LGBTIQ+ Jugendliche berichten häufig, dass sie sich „nirgendwo sicher“ fühlen, insbesondere wenn die üblichen Schutzfaktoren - in den Bereichen Schule, Familie und Freund*innenschaft - unzureichend sind (Dayer, 2022). Jugendliche, deren sexuelle und romantische Orientierung nicht ausschliesslich heterosexuell ist, die sich nicht mit dem ihnen bei der Geburt zugewiesenen Geschlecht identifizieren oder die intergeschlechtlich sind, sind häufig das Ziel von Mobbing und Gewalt im Bildungs- und Freizeitkontext. Um bestehende Angebote sowie Lücken und Bedürfnisse zu identifizieren, hat das Team des Swiss LGBTIQ+ Panel im Auftrag des LGBTI Youth Fund einen Überblicksbericht erstellt. Hierbei haben wir Organisationen, Schlüsselakteur* innen, politische Massnahmen und Projekte identifiziert, die die Bedürfnisse von LGBTIQ+ Jugendlichen in der Schweiz adressieren und ihre Rechte fördern möchten. Die Ergebnisse dieses Prozesses geben einen Überblick über die Bandbreite der verfügbaren Unterstützungsangebote und Dienstleistungen und zeigen gleichzeitig die Unterschiede zwischen den Kantonen auf. Wir schliessen mit allgemeinen Empfehlungen zu Lücken oder Herausforderungen, die in den kommenden Jahren angegangen werden müssen, um den sozialen Wandel hin zu einer inklusiven, gerechten und sicheren Gesellschaft für alle Jugendliche in der Schweiz zu fördern.
The Causal Cookbook: Recipes for Propensity Scores, G-Computation, and Doubly Robust Standardization
Authors: Chatton Arthur , Rohrer Julia M.
Published: September 2023

Recent developments in the causal-inference literature have renewed psychologists’ interest in how to improve causal conclusions based on observational data. A lot of the recent writing has focused on concerns of causal identification (under which conditions is it, in principle, possible to recover causal effects?); in this primer, we turn to causal estimation (how do researchers actually turn the data into an effect estimate?) and modern approaches to it that are commonly used in epidemiology. First, we explain how causal estimands can be defined rigorously with the help of the potential-outcomes framework, and we highlight four crucial assumptions necessary for causal inference to succeed (exchangeability, positivity, consistency, and noninterference). Next, we present three types of approaches to causal estimation and compare their strengths and weaknesses: propensity-score methods (in which the independent variable is modeled as a function of controls), g-computation methods (in which the dependent variable is modeled as a function of both controls and the independent variable), and doubly robust estimators (which combine models for both independent and dependent variables). A companion R Notebook is available at github.com/ArthurChatton/CausalCookbook. We hope that this nontechnical introduction not only helps psychologists and other social scientists expand their causal toolbox but also facilitates communication across disciplinary boundaries when it comes to causal inference, a research goal common to all fields of research.
Effectiveness of Multimedia Condition on Learning Second-Language Vocabulary: A Meta-analysis
Authors: Zhang Caihui , Sala Giovanni , Gobet Fernand
Published: September 2023

Dual coding theory suggests that combining verbal and visual information enhances learning and memory by utilizing two distinct cognitive channels. However, the predictions of this theory have only been partly supported in multimedia second language (L2) vocabulary learning. To examine which are the effective elements in multimedia inputs and identify the most effective learning condition, the present study further clarifies the “domains” in multimedia L2 vocabulary learning. Considering that the learning target (L2 vocabulary) belongs to the verbal domain, the meaningful inputs are then constructed as within-domain (L1-based), cross-domain (picture-based), and mixed-domain (L1+picture-based) conditions. The present investigation conducted three meta-analyses: (a) within-domain vs. cross-domain (20 studies, 51 effect sizes), (b) within-domain vs. mixed-domain (21 studies, 55 effect sizes), and (c) cross-domain vs. mixed-domain (9 studies, 27 effect sizes), for a total of 2,056 participants. The results indicate that the mixed-domain condition consistently outperforms the within-domain condition (g = 0.343, p < 0.001) and the cross-domain condition (g = 0.393, p < 0.01) by more than one-third of a standard deviation. Compared with adults, children benefit more from the mixed-domain condition than the within-domain condition. These findings highlight the benefit of incorporating both L1 words and pictures into L2 vocabulary learning programs.
A few words on the modification of the ruling in the part concerning compensatory damages
Authors: Bróżek Patrycja
Published: September 2023

An important issue that requires in-depth consideration in the context of the issue of enforcement of judgments on the obligation imposed on the perpetrator to compensate for the damage inflicted or to make reparation for the harm suffered by the aggrieved party is the issue of the possibility to modify them (change the manner, scope or even revoke them) in enforcement proceedings. This raises the question: Is the executing authority entitled to make any changes (and if so, what changes) to the part of the judgment that concerns the obligation to compensate for the damage or harm suffered? Whether or not on the grounds of criminal law it is permissible to apply the institutions regulated in Article 453 of the CC, that is, datio in solutum (the essence of which consists in the fact that an obligation expires if the debtor, with the creditor’s consent, performs another service in order to be released from it), as well as in Article 509 of the Civil Code, the so-called assignment of claims (under which the creditor may, without the debtor’s consent, transfer a claim to a third party, unless this would be contrary to the law, a contractual stipulation or the nature of the obligation) and in Article 365 of the CC, that is, alternate obligations, or even in Article 506 of the Civil Code, that is, renewal (novation)? Whether and which amendments, if any, may be made by the court on the basis of Article 13(1) of the EPC? How much influence does the will of the aggrieved party or the will of the offender have on the manner in which such an obligation is to be performed and any modification thereof? The issues outlined are, among others, the subject of a broader analysis within this publication.

This study investigates the modification of pencil lead graphite electrodes with polyglutamic acid using an effective and fast static method to develop a sensor for the detection of enrofloxacin (ENR). The successful fabrication of pGA on the electrode surface was confirmed by scanning electron microscopy, energy dispersive X-ray analysis, and Fourier-transform infrared spectroscopy. The conditions of electrochemical modification, including the applied potentials and number of cycles in the potentiostatic process, were systematically investigated to determine their effects on the ENR electrochemical response. The pH of the electrolyte media was also explored to elucidate the electrochemical reaction mechanism of ENR. The developed electrochemical sensor was evaluated using square wave stripping voltammetry for ENR detection. Under optimal conditions, the sensor demonstrated good reproducibility with a relative standard deviation of 4.3% (from five measurements) for ENR signal detection. A linear relationship between ENR concentration and its peak current was observed in the concentration range of 0.1 to 5 μM, with a high correlation coefficient of 0.9988. The limit of detection for ENR using the sensor was 0.12 μM. Our findings provide valuable insights into the design and optimisation of pencil lead graphite electrode-based sensors for ENR detection in aqueous media.

This study successfully developed Co2SnO4@rGO nanocomposites at various composite ratios of Co2SnO4 and rGO using the sol-gel method. These nanocomposites were then used as heterogeneous catalysts to activate PMS in the heterogeneous catalytic oxidation of Co2SnO4@rGO/PMS as well as the hybrid ozonation system O3/Co2SnO4@rGO/PMS to degrade cefalexin (CFX). The physical-chemical characteristics of the fabricated catalysts were evaluated through nitrogen adsorption-deadsorption, SEM images, EDS mapping, and XRD. The catalytic activity of the nanocomposite was investigated in a degradation reaction of CFX from an aqueous solution. Besides this, CFX degradation kinetics were determined by fitting experimental data with a first-order model. The results showed that at the composite ratio of 2-Co2SnO4 and 1-rGO for CFX degradation had the highest efficiency reaching 95.07 and 99.07% for Co2SnO4@rGO/PMS and O3/Co2SnO4@rGO/PMS systems, respectively. The degradation of CFX in the O3/Co2SnO4@rGO/PMS system was higher than that of Co2SnO4@rGO/PMS. The results were due to a remarkable increase in SBET in 2-Co2SnO4@1-rGO compared to both Co2SnO4 and rGO, facilitating a catalytic reaction occurring on the catalyst’s surface. Moreover, the coupling between O3 and Co2SnO4@rGO/PMS generated a synergetic effect leading to the generation of more *SO4- and *OH radicals, which enhanced the CFX degradation rate in the hybrid ozonation system. These primary findings illustrated that the nanocomposite catalyst 2-Co2SnO4@1-rGO was feasible for the activation of PMS in hybrid ozonation to effectively degrade antibiotic residues from wastewater.

The current study was designed to investigate the anti-hypertensive effects of a standardised flavonoid extract from Diospyros kaki L.f leaves (DK extract) on cortisone acetate-induced hypertensive rats. Hypertension was induced in Wistar rats by subcutaneously injecting 2.5 mg cortisone acetate daily and by maintaining the rats on a 1% sodium chloride diet for a period of 28 days. The hypertensive rats were treated daily with DK extract (50 and 100 mg/kg of body weight; p.o.) or captopril (20 mg/kg of body weight; p.o.), a reference drug, for 14 consecutive days. The blood pressure and heart rate of awake rats were measured using a non-invasive tail-cuff method. The heart weight and left ventricular wall thickness of rats were measured. In vitro angiotensin-converting enzyme (ACE) inhibition activity of the DK extract and captopril were analysed. DK extract significantly and dose-dependently reduced systolic and diastolic blood pressure in the hypertensive rats. There were no significant changes observed in heart rate. The cortisone acetate-induced hypertensive rats had increased heart weight and left ventricular wall thickness. These actions were attenuated by the treatment of DK extract (100 mg/kg) and captopril. Moreover, DK extract inhibited ACE activity in vitro with an IC50 of 4.71±0.53 μg/ml. Our findings demonstrate that DK extract exerted anti-hypertensive effects and alleviated ventricular hypertrophy in the cortisone acetate-induced hypertensive rats and these actions occurred at least in part via ACE activity inhibition.

Terjadinya penyimpangan biaya dan waktu yang signifikan mengindikasikan adanya pengelolaan proyek yang buruk. Dengan adanya indikator prestasi proyek dari segi biaya dan waktu ini memungkinkan tindakan pencegahan agar pelaksanaan proyek berjalan sesuai dengan rencana yang telah dibuat. Pengendalian merupakan salah satu fungsi dari manajemen proyek yang mempunyai tujuan agar pekerjaan-pekerjaan yang dikerjakan berjalan sesuai dengan  sasaran yang telah ditetapkan tanpa banyak penyimpanganKonsep “earned value” merupakan salah satu alat yang digunakan dalam pengelolaan proyek yang mengintegrasikan biaya dan waktu. Tujuan mengetahui kinerja yaitu untuk melakukan monitoring proyek dan mengendalikannya, sehingga jika terjadi penyimpangan dapat segera di ambil tindakan. Konsep earned value menyajikan tiga dimensi yaitu penyelesaian fisik dari proyek (the percent complete) yang mencerminkan rencana penyerapan biaya (budgeted cost), biaya aktual yang sudah dikeluarkan atau yang disebut dengan actual cost  serta apa yang yang didapatkan dari biaya yang sudah dikeluarkan atau yang disebut earned value. Dari ketiga dimensi tersebut, dengan konsep earned value, dapat dihubungkan antara kinerja biaya dengan waktu yang berasal dari perhitungan varian dari biaya dan waktu (Koppelman, 1994).Hampir sebagian besar proyek hanya mengandalkan kurva S untuk mengendalikan proyek atau kinerja waktu sementara kurva S tidak bisa menginformasikan biaya. Dengan adanya kinerja biaya nyaris tidak pernah terpikirkan untuk di teliti.Pada saat ini Pembangunan Gedung tersebut mengalami percepatan waktu. Dengan melihat data lapangan pada time schedule, pelaksanaan proyek mengalami percepatan. Kumulatif rencana sampai dengan akhir minggu ke-8 adalah 53,98% sedangkan kumulatif realisasi baru mencapai 80,95% sehingga terdapat percepatan sebesar 26,97%. Waktu pelaksanaan dalam kontrak mulai tanggal 20 Januari 2022 sampai dengan tanggal 19 April 2022.
An Investigation into the Practice of Human Naming
Authors: P. M. Suresh Kumar
Published: September 2023

Every human being on earth is designated with a name. This eventually means that the crores of people comprising both men and women have their own names, and put together it is an endless number.  With such a multitude of names, compiling a vast repository is rather impossible to conceive. Among the enormous variations, there are resemblances although very few are exactly the same in all respects. Although used as a practice to establish identity since time immemorial, one could see some emerging patterns that distinguish traditional names from modern names. What is most astonishing is that names have meanings. These meanings signify certain objects, characters, features, or symbolic representations of notions. This points to the need for an effort to bring out the basis of such vast nomenclature. Naming looks simple but it evolves out of a careful choice and complex process involving search, screening, selection and rejection, acceptance and approval, and finally decision on suitability. This happens slowly and silently. Name is assigned at the babyhood or early childhood. It becomes a person's lasting identity never to be erased by time. The thesaurus of nomenclature opens up a voracious glossary of names. It may be country-specific or region-specific, religion-specific or culture-specific. It has linkages with the educational and occupational class, ancestry and lineage, culture of the group, kinship, fashion, auspicious, or fantasy. Names that are universal transcend the boundaries of region and religion. This study is an attempt to examine the process of nomenclature as a universally accepted practice based on an extensive sample of over two thousand names spread over three generations from among the Hindu population of Kerala. The paper also aims to delineate various typologies by attempting a classification. Although the study was conducted among the Hindus in Kerala, the findings largely apply to the whole of the country.

Nitrogen fertilization in Virginia tobacco monitored by a multispectral platform boarded in a remotely piloted aircraft
 
ABSTRACT: Tobacco production is one of the main activities of small farming in Southern Brazil, due its high economic value. Brazil is ranked as the second largest producer and the largest exporter in the world. The objective of this work was to apply Precision Agriculture tools, good management practices and variable rate nitrogen fertilization in Tobacco Virginia. The study was carried out in a commercial field of Virgínia ​​tobacco cultivar in the municipality of Agudo/RS. Aerial images were carried out to obtain the MPRI, NDRE, NDVI and NDWI vegetation indexes using multispectral images from the RedEdge-Mx sensor onboard a Remotely Piloted Aircraft, and the indices were also generated with data from the FieldSpec-HH2 spectroradiometer, in various phenological stages of the tobacco. Data analysis was performed using multivariate statistics with the Factor Analysis method. The rates of nitrogen input in the experiment were adequate to obtain a range of nitrogen content in the leaves, yield and vegetation indices. The results showed that PA tools applied in tobacco crops could reduce nitrogen rates in relation to farmer business as usual, and have the potential to increase economic returns, productivity, leaf quality and net income.

Higher Education Internationalization and English Language Instruction. Xiangying Huo. Springer, 2020
Authors: Chen Qinghua
Published: September 2023

The book "Higher Education Internationalization and English Language Instruction" is an autoethnographic work that examines the intersectionality of race and language in the Canadian higher education system. Through personal stories and narratives, the author explores themes such as native-speakerism, writing centre tutoring, multicultural education, and social justice. The book makes two significant contributions: first, it amplifies the voice of racialized individuals through the application of Critical Race Theory to personal experiences and diaries, serving as a springboard for thought and an invitation to dialogues on transformation. Second, it demonstrates the potential of personal narratives to reveal ideas that are often overlooked in positivist approaches, providing insight into methodological approaches that graduate students and young researchers can adopt. The book concludes with practical implications for addressing discriminatory systems and practises in universities to promote diversity and inclusiveness. The book follows a standard format for scholarly works and provides a useful background on the internationalisation of higher education and the significance of English as a medium for multiculturalism in Canada.

Keissl. 3.45, Nigrospora oryzae (Berk. & Broome) Petch. 18.77. As a result of the conducted studies, it was identified that bacteria Bacillus methylotrophicus 10 had an inhibitory effect on Fusarium sporotrichioides Sherb. 23.2 ‒ 77,4%, Alternaria alternata (Fr.) Keissl. 3.45 ‒ 66.6% and Nigrospora oryzae (Berk. & Broome) Petch. 18.77 ‒ 86.7%, while bacteria Phyllobacterium ifriqiyense 1 showed activity against phytopathogens by 45.1%, 63.1%, and 65.0%, respectively. Thus, both strains of dominating rhizospheric bacteria have high antagonistic activity against phytopathogenic micromycetes, which gives grounds for their further study

The high yield of grafted grape seedlings and their quality depend on many factors, including the quality of the grafting and rootstock components, which is also determined by proper care of the parent grafted and rootstock vines. Their agricultural techniques should be aimed at better growth and maturation of shoots. The technological technique of breaking off the shoots is mandatory on parent vines, partial removal of inflorescences is not so common in the agrotechnics of parent vines, but it has a positive effect on the overall development of plants. Parent plantings should be irrigated, if possible, since insufficient moisture supply adversely affects the condition of vines throughout the growing season and wintering. This paper investigated the effect of partial removal of inflorescences (inflorescence load of 100%, 75%, and 50% of their total number) on parent vines and the effect of different irrigation regimes (pre-irrigation soil water levels of 90%, 80%, and 70% of the minimum water content) on the state of parent vines were investigated, specifically on physiological, biochemical, and biometric indicators of plants. It was shown that irrigation of vines and reducing the load of inflorescences to 50% and 75% of their total number stimulated the accumulation of chlorophyll in the leaves of parent plants, improved the watering of leaf tissues, and contributed to an increase in the intensity of respiration during active growth and development of grapes. A positive effect of irrigation and a reduction in the load of vines with inflorescences up to 50% and 75% on the agrobiological indicators of parent vines was noted. The highest values of the total length of the shoots and the degree of their maturation were found in the vines of the variants with PSWL 90% MWRC 50% inflorescences, 80% MWRC 50% inflorescences, 70% MWRC 50% and 75% inflorescences. Therefore, effective irrigation regimes and reducing the load of vines with inflorescences contributed to the growth of medium and strong full-fledged shoots, which are more productive

An error analysis study was conducted in order to investigate the errors of fourth grade Turkish students with regard to English speaking skill. Demirel (2012) stated that among the skills in foreign language teaching, the speaking skill might be the most difficult skill to acquire. There are various reasons behind the scene such as learning difficulties in speaking a foreign language, the continuum of these learning problems in the following years, hesitation of students to speak English and attend English courses, exam-oriented learning and teaching environment, and not putting the information into the long-term memory. Considering these reasons, the present study showed an attempt to examine errors in the speaking skill of primary school students. Error analysis is employed to find the sources of errors by making an in-depth investigation (Corder, 1974). In the current study, via a quasi-experimental research design, a 9-week implimentation was carried out to improve the speaking skills of the participants. Descriptive analysis was used to analyze of the data. The results of speaking pre-tests and post-tests in the experimental (n=17) and control groups n=(15) were utilized. "English Speaking Skills Rubric for Primary School Students" was used as a measurement tool. The outcomes were analyzed by employing Man Whitney U test. In the error analysis focusing on the development of students' speaking skills based on the difference scores, the type of sub-dimension that the students were found to be more successful, respectively, as follows: Task achievement 10.7 difference points (out of 20 points) 53.5%, Comprehension and expression 4.7 difference points (out of 10 points) 47%, Fluency 7 differences points (out of 15 points) 46.2%, Vocabulary 8 differences points (out of 20 points) 40%, Grammar and structure 8 differences points (out of 20 points) ) 40%, Intelligibility 6 points (out of 15 points) 39.6%. In this situation, while the most errors were detected in the intelligibility sub-dimension, the least errors were observed in the task achievement.
