Literatürdeki çalışmalar daha çok İslami endekslerle konvansiyonel endeksler, İslami hisse senetleri ile geleneksel akranları ve sukuklarla geleneksel tahvillerin karşılaştırılması şeklinde iken, bu çalışmada farklı olarak İslami tahvil (kira sertifikası) ile 2 yıllık devlet tahvili, döviz kuru ve BİST100 endeksinin performans oranları karşılaştırılmıştır. Bu çalışmanın amacı, “kira sertifikasının faiz, döviz kuru ve hisse senedi piyasasından kaynaklanan risklere karşı korunaklı ve portföyde dengeleyici bir finansal varlık olabilir mi?” sorusuna cevap bulmaktır. Çalışmada 2006-2020 dönemi için Sharpe, Bilgi ve Sortino performans oranları kullanılarak kira sertifikasının, 2 yıllık tahvil faiz oranının, ABD doları/TL döviz kuru ve BİST100 endeksinin performans ölçümleri yapılmış ve analiz edilmiştir. Elde edilen bulgulara göre, analiz edilen 5 dönemden dördünde elde edilen performans oranları açısından, kira sertifikası fonunun hisse senetleri, döviz kuru ve faiz oranı riskine karşı korunaklı bir yapıya sahip oldukları görülmektedir. Bu durum özellikle 2. dönem olan 2008-2010 küresel kriz ve sonrası toparlanma döneminde daha bariz olarak görülmektedir.
Software Quality Prediction Method Using Fuzzy Logic
Authors: Et. al. Ritu,
Published: June 2021

: Software Quality is the key priority of today’s marketplace and software development organization to which a system, technique, or factor meets particular requirements and conditions. Soft computing techniques play a vital role in developing software engineering applications. In this paper, we have identified five parameters: Reliability, Efficiency, Usability, Maintainability, and Portability for accessing the level of quality of software. A fuzzy logic-based intelligent identification methodology has been proposed to access the quality of particular software-based on five parameters. The proposed identification scheme takes these five parameters as input and predicts the quality of the software using the fuzzy rule base which is generated using various studies. As this scheme takes five inputs and each input is divided into three regions i.e. ‘Low’, ‘Medium’, ‘High’ and thus a total of 35 i.e. 243 rules has been generated to analyze the software quality. Furthermore, Mamdani fuzzy model has been used as the reference model. To show the effectiveness of the proposed methodology, simulation results have been performed in MATLAB, which shows that the software's quality closely matches with the actual one.

Authors: Pham Huu Kien , Nguyen Hong Linh , Pham Xuan Hien , Nguyen Thi Thuy Linh , Phan Dinh Quang , Giap Thi Thuy Trang
Published: June 2021

In this paper, we perform a simulation about liquid GeO2. The structure and diffusion process are analyzed through the radial distribution function, the distribution of GeOx (x = 4, 5, 6) structural units, length distribution, angle distribution, and data visualization. Simulation results show that the structure of liquid GeO2 composes clusters of GeO4, GeO5, or GeO6. These clusters have sizes depending on pressure and are distributed heterogeneously in space. This result confirms the origin of dynamical heterogeneity in the liquid oxide systems. In addition, the diffusion coefficient of Ge and O decreases upon pressure. We show that the diffusion relates to the breaking bond Ge-O.
Controlled growth and characterization of monolayer MoS2 by using metal-organic chemical vapor deposition
Authors: Do Le Quyen , Nguyen Anh Duc
Published: June 2021

Recently, novel physical properties originating from quantum confinement endow the twodimensional (2D) transition metal dichalcogenides, such as MoS2, or WSe2 to attract a great deal of attention. However, the synthesis of 2D-TMDC has to be still limited, in which the precursors are almost based on high vapor pressure inorganic materials, that produce a smallscale film, and it is mainly performed only on conventional Si\SiO2 substrate. In this work, we successfully synthesize the atomic thickness of 2D-MoS2 films by using metal-organic chemical vapor deposition (MOCVD) on several kinds of substrate, namely silicon (Si), silicon dioxide (SiO2), graphite foil, or fluorine-doped tin oxide (FTO). The morphology of samples is observed by field emission scanning electron microscopy (FE-SEM), and scanning transmission electron microscopy (STEM). The lattice vibrational and optical properties are investigated by Raman and photoluminescence (PL) spectroscopies, respectively. With the same MOCVD growing condition, as-obtained samples exhibit the hexagonal configuration (2H phase), whereas the surface morphology and the thickness show a discrepancy, depending on the substrates.

Authors: Doan Van Thuoc , Nguyen Phuc Hung
Published: June 2021

The effect of physical parameters such as temperature and pH on the production, activity, and stability of α-amylase from Bacillus subtilis V37 was investigated. The results indicated that the optimum culture conditions for enzyme activity were pH 7.0 and 35 oC. The optimum pH and temperature for enzyme activity were 6.0 and 70 oC. The crude enzyme was found to be stable in the pH range of 5.0 to 7.0. The enzyme was stable for 1 h at a temperature from 30 to 80 oC; nearly 100% of enzyme activity remained at temperatures of 30 - 40 oC, and about 34% of original activity remained at a temperature of 80 oC. These features demonstrated that α-amylase from B. subtilis V37 can be applied in many areas such as the food, fermentation, and animal feed industries.

Published: June 2021

Perilla frutescens (L.) Britton is well known as an herb and also a medicinal plant in Vietnam and many East Asian countries. Perilla juice (Shiso) is a familiar drink of the Japanese; however, there are very few studies on the alcoholic fermentation of perilla juice to produces alcoholic beverages. In this study, we investigated the growth and fermentation ability of yeast strain NM3.6 in perilla leaf extract to produce a low alcoholic beverage. The results showed that this strain grew well in perilla leaf extract supplemented with sucrose 70 g\L, pH 5. The OD610 value of 18.2 was obtained after 24 hours of cultivation at 30 °C and 180 rpm. This strain also performed a good fermentation ability of perilla leaf extract supplemented with 200 g\L of sucrose, pH 4.5, and 10% of seed culture. After 9 days of the main fermentation at 30 °C and 14 days of the secondary fermentation at 10 °C, alcoholic content reached 3.22% (v\v) and fermentation efficiency reached 57.6%, sensory scored 16.7 points. The fermented perilla leaf extract had unchanged flavonoid content, total phenolic content (0.235 mg\mL) was higher compared to that of the original leaf extract (0.196 mg\mL). This alcoholic fermentation juice met a standard of sensory and quality for low alcoholic drinks fermented from fruit and vegetable extracts.

Authors: Hoang Thi Kieu Oanh
Published: June 2021

This article assesses climatic conditions for tourism by using Tourism Climate Index - TCI, published by Mieczkowsk (1985). This is an experimental synthetic climatic index that evaluates simultaneously the influence of 7 climatic elements as maximum average temperature (oC), minimum average humidity (%), average temperature (oC), average humidity (%), the number of sunny hours, windy speed of Con Dao island. The results of TCI within 12 months in Con Dao island compare to “Classification of advantageous levels of climate for tourism” of TCI (Mieczkowsk, 1985) which shows the advantages of Con Dao for relaxation tourism all year round. The period from December to April is the most favourable time for tourism activities in Con Dao because the TCI index reaches from Good to Very good, while the suitable time is from May to November, due to rainfall and high speed of wind during the rainy season.
The space of V.S. Naipaul’s novels in the light of multicultural theory
Authors: Dinh Thi Le
Published: June 2021

It is a self-evident truth that V.S. Naipaul 's novels hold powerful appeal to readers worldwide thanks to his real-life experience of migration and changes in psychology and lifestyles between multicultural spaces. The writer has successfully created a diversified, rich, traditional hybrid space of the Trinidad and Tobago, an African cultural space before the historical upheavals, and English villages and towns after the the golden age of wealthy nobles and landowners. Studying these spatial dimensions through the prisms of Doreen Massey's multicultural theory will offer an insight into the relationship between place and identity, as well as the artistic talent of V.S. Naipaul, a passionate and gifted writer, who devoted his life to “the history of oppressed peoples”, contributing a great voice to “marginal” cultures.

Authors: Hoang Thi Cuong
Published: June 2021

This paper uses typology methodology to examine the system of topics and themes in anticolonial works written by Nguyen Dinh Chieu. Thepaper contends that in general Chieu’s anticolonial prose and versepresent styles of Confucian scholars struggling against colonialism; and in particular, they bear the characteristics identifyingindividual Nguyen Dinh Chieu as well as the distinct features ofregional South Vietnam. The system of topics and themes in Nguyen Dinh Chieu’s literary works are centered on the very purpose of “observingethics, protecting people, showing loyalty to King and love to country”. Chieu enthusiastically defended Confucianism against other religions. He failed to well understand the nature of Christianity as a reason of limited access to information. The author had adeep-seated aversion to Western civilization for he recognized it in a connection with the invasion of colonials. Like other Confucianscholars of his time, Chieu unsuccessfully pushed his perception further so that he could notice the duality of colonialism.

Authors: Le Hien Chuong
Published: June 2021

During the history of Vietnam in the medieval period, the area of Nghe An - Ha Tinh was often considered the “key land” of the country, but it was also the place where “poor land, poor residents”, suffered with many natural disasters and enemy sabotages. In comparing with the Northern region, the socio-economic development process in Nghe An – Ha Tinh was usually one step behind and more or less different. By the second half of the eighteenth century, in a new context full of events and changes, the land and Nghe An – Ha Tinh people step by step established a new position with many great marks on the national level, especially in the political arena, academic fields, literature. The rise of Nghe An – Ha Tinh during this period showed great changes in the development and correlation of regional forces in Vietnam in the late eighteenth and early nineteenth centuries.

To gradually professionalize social work in hospitals, the establishment of social work units in hospitals is necessary in Vietnam's current context. The study's objective was to evaluate the establishment results of social work units among some hospitals in Vietnam for the period 2011-2020. The study was conducted from December 2019 to March 2020, with 503 hospitals, including hospitals at the central, provincial, and district levels nationwide. Our findings showed that the establishment prevalence of social work units among some hospitals was relatively high (exceeding the initial target). Human resources on social work were why some hospitals have not yet established social work units (accounting for the highest prevalence with 65.0%). The study results also showed that the larger the number of planned beds, the higher the establishment prevalence of social work units. There were four parts under social work units, including the patients’ support (59.6%), the communication (44.9%), the mobilization and resources allocation (40.8%), and the customer care (44.1%). The study also gave some suggestions to the Ministry of Health to establish social work units to be more effective in the coming time at some hospitals nationwide.

A Novel Weighted Ensemble Method to Overcome the Impact of Under-fitting and Over-fitting on the Classification Accuracy of the Imbalanced Data Sets
Authors: Ghulam Fatima  , Saeed Sana
Published: June 2021

In the data mining communal, imbalanced class dispersal data sets have established mounting consideration. The evolving field of data mining and information discovery seeks to establish precise and effective computational tools for the investigation of such data sets to excerpt innovative facts from statistics. Sampling methods re-balance the imbalanced data sets consequently improve the enactment of classifiers. For the classification of the imbalanced data sets, over-fitting and under-fitting are the two striking problems. In this study, a novel weighted ensemble method is anticipated to diminish the influence of over-fitting and under-fitting while classifying these kinds of data sets. Forty imbalanced data sets with varying imbalance ratios are engaged to conduct a comparative study. The enactment of the projected method is compared with four customary classifiers including decision tree(DT), k-nearest neighbor (KNN), support vector machines (SVM), and neural network (NN). This evaluation is completed with two over-sampling procedures, an adaptive synthetic sampling approach (ADASYN), and a synthetic minority over-sampling (SMOTE) technique. The projected scheme remained efficacious in diminishing the impact of over-fitting and under-fitting on the classification of these data sets.

Transvaginal ultrasound for cervical assessment versus digital vaginal examination during active phase of labour
Authors: Hefila Nermeen Mohamed , Elfazari Hisham Adel
Published: June 2021

Background: Ultrasound is found to have many uses in obstetrics. As the transvaginal ultrasound is used to examine the cervix in non-pregnant cases, it’s also can be used in pregnant cases to detect any cervical changes early in pregnancy, in cases of cervical incompetence, or late in pregnancy in labour to detect progression of cervical changes. Vaginal birth occasionally requires urgent medical intervention to avoid harm to the labouring woman and her baby. Intrapartum ultrasound is a simple technique that improves the understanding of abnormal labour and provides a more scientific basis for assessing labour. In this study, two hundred pregnant women, full term, non-complicated, single tone, cephalic presentation, active stage of labour, attending El-Shatby Maternity University Hospital labour ward were recruited for this study.Methods: Intrapartum transvaginal ultrasound is done by the obstetrician followed immediately by digital examination done by a second obstetrician in charge to avoid bias.Results: The results revealed that comparison between mean cervical length measurements assessed by TVUS and digitally revealed statistically significant difference with p<0.001. Also, comparison between mean cervical diameter measurements assessed by TVUS and digitally reveals statistically significant difference with p<0.001.Conclusions: The  TVUS is a suitable alternative to digital examiation  in assessing labour progress because it is well accepted, minimal-invasive, less painful and with minimal infectious risks and good tool for estimating labour progress.

Authors: Shilong Danaan J. , Bot Gyang M.
Published: June 2021

Background: Intracranial suppurations are rare but can be fatal entities consisting of pus collection within the intracranial cavity.  The aim of the study was to document the clinical and radiological findings in our patients and the outcome of treatment.Methods: A retrospective analysis of all consecutive patients presenting to the Jos University Teaching Hospital from January 2012 to December 2019. Data of interest were retrieved from their folders and entered into SPSS version 22 and descriptive statistics run on the variables.Results: There were 33 patients within this period, but only 21 had complete records and thus used for the analysis. The median age was 18 years (IQR=29), males accounted for 81% of the patients. The median time to presentation was 14 days (IQR=23). The most common cause of abscess in our series was trauma (surgical and non-surgical) in 38.1%, followed by contiguous spread from the ear or paranasal sinuses (23.8%). The most common symptom was fever occurring in 61.9%, followed by headache 42.8%. In two thirds of the patients, the abscess was intra-axial (the frontal lobe being the most common site). Patients were managed surgically with either a craniotomy (28.6%) or a burr whole (71.4%). A positive culture was obtained in 33.3% of cases.Conclusions: Intracranial suppurations are uncommon, but can occur in the setting of predisposing factors. A high index of suspicion is required to clinch the diagnosis.

Published: June 2021

Coronavirus disease 2019 (COVID-19), caused by a strain of coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a global pandemic affecting billions of lives and posing a stiff challenge to the delivery of routine healthcare across the world. The new second wave of COVID-19 in India presents with higher rate of infection and percentage of asymptomatic and mildly symptomatic cases is much higher than before, which means more people are spreading the disease. People with co-morbidities such as pre-existing cardiovascular conditions are at risk of suffering from severe complications of COVID-19 including acute respiratory distress and multi-organ failure. The pandemic has also resulted in people deferring routine care for conditions such as hypertension, diabetes and other cardiometabolic diseases. Initial reports also linked major CV drug classes such as the angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) to adverse outcomes in COVID-19 patients. While subsequent reports have disproved these earlier findings, the science is rapidly evolving and the information overload has served to confuse general practitioners and consultant physicians alike. This review examined the practical considerations in terms of cardiocascular complications, effect of drugs, older adults and tele-consultation for CV care during COVID-19 pandemic.

Authors: Kumar K. Manoj , Jeyabalaji K. M.
Published: June 2021

Background: Prehypertension is a major public health concern. The condition is much prevalent in India and is often associated with other cardiovascular (CV) risk factors and independently increases the risk of hypertension and subsequent cardiovascular events. Several studies have shown microalbuminuria as a sensitive marker for predicting CV risk in pre-hypertensive. The objective of this study was to assess the prevalence of microalbuminuria in prehypertension and to determine its association with electrocardiogram (ECG) and echocardiographic (Echo) parameters indicative of CV risk.Methods: This cross-sectional study included a total of 75 subjects aged between 22 and 50 years, with prehypertension attending the medicine department of a tertiary care teaching hospital in Chennai, Tamil Nadu from April 2012 to November 2012. All the study subjects were evaluated with ECG and echo for cardiac changes. Statistical analysis was performed using SPSS software trial version-16 to determine the association of microalbuminuria with cardiac changes.Results: The prevalence of microalbuminuria among the included subjects was 60%. Mean value of urinary excretion of microalbuminuria was 90±2.1 µg/dl with a male preponderance in this study. Pre-hypertensive subjects with microalbuminuria had significant changes of left ventricular hypertrophy (LVH) as evident in ECG than those without microalbuminuria. Microalbuminuric prehypertensive subjects also had significant echocardiographic changes like LVH and diastolic dysfunction than those without microalbuminuria.Conclusions: The cardiovascular changes like left ventricular hypertrophy and diastolic dysfunction were evident in younger age among pre-hypertensives with microalbuminuria than those without microalbuminuria.

Many applications have been previously reported that laser is used in the field of endodontics. It is used in pulp diagnosis, shaping and disinfection of the root canal, endodontic surgeries, modifying the dentin structures, pulpotomy and pulp capping. Our present study aims to review some applications of laser used in the field of endodontics. According to the evidence from current studies in the literature, vital pulp therapeutic approaches for pulpotomy can significantly lead to efficacious and bloodless outcomes by using laser for the following processes: Coagulation, vaporization, and sealing of the blood vessels with potentially sterile minute wounds with no complications. Many advantages have been previously reported for using laser within endodontic surgical procedures, such as coagulation, sterilization, selective absorption, precision, lower rates of complications as inflammation and edema, getting clean, well-sealed surgical wounds, enhanced disinfection characteristics, reduced painful sensations, decreased required sutures due to better hemostasis, and reduced bleeding. On the other hand, applying some laser modalities might not be adequately efficacious according to previous studies in the literature. We recommend that further human prospective to conduct investigations for further validation of the current evidence.

Published: June 2021

The operational abilities of the members of the army are defined by the factors of morphology, function, levels of motor skills, health, etc. In special brigades, a high level of motor skills is required for the successful realization of assigned tasks. The most important motor skills of the Special Brigades members are endurance, strength, coordination, agility and speed, as well as balance, precision and flexibility. These parameters must be interrelated in order to expect maximum performance. The aim of the research was to determine whether there is a connection between speed and specific motor abilities of the special brigade members in the Serbian Armed Forces(SAF). The sample consisted of 74 respondents, members of the 63rd Parachute Brigade from Nis. To determine the speed, the following tests were used: sprint at 10m, 20m and 30m. Specific motor skills were assessed by the following tests: push-ups on the ground for 2 minutes, lifting the torso off the ground for 2 minutes, 3200m running, 7m rope climbing. The canonical correlation analysis was applied to determine the relationship between speed and the parameters of specific motor abilities. Data processing was conducted using the statistical package Statistica 8.0. The significance level was .05. The results indicated the interrelation of speed and specific motor abilities with one pair of statistically significant canonical factors at the significance level of .01 (p = .000). The isolated pair of canonical factors was explained with 43% of the common variability.

The subject of this research are the motor abilities of track and field athletes and calisthenics practitioners. The aim of the study was to examine the differences in the motor abilities of track and field athletes and calisthenics practitioners. The research was conducted on a sample of a total of 11 participants from the City of Belgrade: 6 track and field athletes (group 1) and 5 calisthenics practitioners (group 2). The standing long jump (SLJ), standing triple jump (STJ), 20 m sprinting, 50m sprinting (20 flying start) tests were used for the assessment of motor abilities. Descriptive and comparative statistical methods were used for data processing. The results of the research showed that track and field athletes perform better in the examined motor abilities. The results of descriptive statistics showed that track and field athletes perform better in all tests that assess the ability of power, speed, and acceleration. The results of comparative statistics, using the t-test for independent samples showed that a statistically significant difference (p <0.05) was found between the groups. These differences can be attributed to the training of track and field athletes, which is more planned, systematic and specific in relation to calisthenics workouts.

The quality of life is a broad concept influenced by the physical health of an individual, their mental state, and the degree of independence, social relations and numerous variables from the environment. Sports and recreational activities can contribute to improving the quality of life of people with disabilities. The main goal of the survey is to determine the importance of sports and recreational activities for people with disabilities. The sample consists of 44 respondents, aged 18-63 (M=34.5) years. Respondents are engaged in various sports (competitive and recreational). Two questionnaires were used in the survey: the General Questionnaire (which contains questions on general socio-demographic data, as well as questions about training, motives for playing sports, the perception of the impact of sports on various aspects of an individual’s life) and the Health Questionnaire (EQ-5D) which examines the health status of the general population and people with chronic diseases and/or disabilities. Based on the obtained results, it was found that people with disabilities perceive sport primarily as an opportunity for socializing and recreation, and half of the respondents view it as a profession. People with disabilities have motivation and desire to play sports and are aware of the positive outcomes that result from sports and recreational activities. The professional and scientific public could contribute to improving the conditions for them. It is necessary to open this topic and point out its importance so that a larger number of people with disabilities could have the opportunity to engage in a variety of sports and recreational activities.

Authors: Milićević-Marinković Bojana
Published: June 2021

The application of adapted sports activities has been increasingly prevalent and accepted with the aim of rehabilitation and occupational therapy of persons with developmental difficulties and disabilities. The importance, the positive effects and the wide spectrum of impacts on psycho-physical abilities are equally relevant for persons with disabilities, and the positive impact on social skills of this population is also beyond any doubt. The subject of this paper is a theoretical review of the research concerning the impact and application of adapted sports activities on motor and social abilities of persons with Down syndrome. The aim of the paper is to point out the adapted sports activities that have essential importance and impact on the overall progress of persons with disabilities and developmental difficulties. Sport, physical activity, and any kind of rehabilitation based on movement and exercise, will undoubtedly have a positive impact on users. The bibliographic speculative method was used as a research method, various literature was consulted and data relevant to the work were collected. Down syndrome as a genetic problem accompanied by many complications, from physical to intellectual ones, can be alleviated exactly by including sports activities in everyday life of persons with Down syndrome. If an adapted sports activity is individually tailored to the psychosomatic abilities of a person, as well as towards the goal they should reach, positive effects will undoubtedly show, both in physical and social functioning of persons with Down syndrome, with the ultimate goal being to improve the life quality of this population. The paper includes some studies in the fields of sports, medicine and psychology, which prove that appropriately dosed, applied and adapted sports activity can have a positive impact on persons with Down syndrome and that its application is very much desirable throughout entire life of this population.
Body composition analysis: The most common test models and research methods
Authors: Đurđević Dragan
Published: June 2021

Accurate and valid analysis of body composition is important for the diagnosis of nutritional status, training impact assessment, the body's response to nutritional and therapeutic interventions, growth and development of the organism, and health risk assessment. With the increasing prevalence of chronic non-communicable diseases, obesity, the need for different models and methods of body composition analysis has also increased. This review paper aimed to show the most commonly used methods for body composition analysis and to give a brief insight into the current techniques. The methods for analysing body composition vary in their accuracy and reliability and in practice the use of appropriate methods depends on the interest and the required accuracy, e.g. dual-energy X-ray absoptiometry (DXA) as the gold standard for determining bone mineral density, or magnetic resonance imaging (MRI) as the gold standard for soft tissue and organ analysis. These methods, along with computed tomography (CT), hydrodensitometry and plethysmography, are routinely used in clinical medicine, and due to their complexity, availability and high prices, they are mostly used in sports medicine for research purposes. In sports medicine, the anthropometric method and bioelectrical impedance analysis (BIA) are mostly used, due to their simplicity and comfort for the examinees. The best assessment of body composition can be obtained by a combination of several methods - a multi-component model, which can increase the accuracy and reliability of the obtained data, and health risk can be assessed with greater certainty.

Also, the most influential causes of drug abuse among them were Peer influence at 90.1%, family background at 57.1% and availability of drugs at 30.8%. Lastly, 89.6% of the students had poor grades due to drug abuse alongside 78.6% of them affected by low concentration span and lack of interest in studies. The study, therefore, inferred that there is a high of drug ab prevalence use amongst secondary school students with family, peers as well as availability contributing to the onset of drug abuse.The study concluded that drug abuse interferes with academic performance indicators of secondary school students in Teso South Constituency.
The Impact Of The Question-Driven Technique On Developing Efl Jordanian Seventh Graders' Grammatical Competence
Authors: Al-Zawahrah Ahmad
Published: June 2021

This research paper is aimed to examine the impact of the question-driven technique on developing EFL Jordanian seventh graders' grammatical competence. To this end, the researcher has redesigned the targeted grammatical material and constructed a grammar test focusing mainly on those grammatical themes given in the seventh grade textbook. The researcher has selected two sections (A & B) of the seventh grade; section A was assigned as a control group, the other one was assigned as an experimental group. The results of the study revealed that the students who have been taught inductively through the Questioning technique had gained better scores than those who have been taught deductively. It has also shown that the majority of the experimental group had more willingness and desire to participate in the class discussion. Also, it can be noticed that the use of the questioning technique is suitable for all types of learning styles and proficiency levels. Another important aspect to which the results of this study could be attributed is the adequate number of opportunities given for students to practice the targeted grammatical rules. In this regard, it sounds important to raise the strong effect of the scaffolding and modelling strategies in facilitating and easing the implementation of the questioning technique while teaching grammar.
