Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Foreign language teaching and learning is one of the topics in the field of K-12 education and adult learning. Most of the current research studies tend to focus on the development and training of foreign language learners. However, issues such as teaching strategies, methodologies, classroom management, and personal beliefs of teaching and learning are neglected. As teachers are primary tools to deliver lessons at all different levels, educators and researchers are increasingly concerned about how teachers’ beliefs and personal background may influence classroom management, curriculum and instruction planning and expectations of students. The current study is a literature review of the concept of teachers’ beliefs, followed by a review of studies exploring teachers’ beliefs using different methodologies. The relationship between teachers’ beliefs and teachers’ classroom practices is also discussed, along with factors influencing teachers’ beliefs in teaching professional development courses.
Contribution/ Originality
This study contributes to the existing literature on teachers’ personal beliefs and teaching behaviors. The paper's primary contribution is also to study how teachers’ personal beliefs influence their classroom management, teaching styles, and instructional feature.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Virtualization technology has been around for many years, and its use is increasingly becoming common in education, in general and in computing fields, in particular. This can be attributed partly to its potential to reduce costs, boost efficiency and overcome limited resources through its virtual applications such as servers, storage devices and networks. However, the question is: "would that be at the cost of the quality of learning?" Besides, the way virtualized environments impact motivation needs further clarification, since it is a neglected area of research. This quasi-experimental study tried to address such questions through investigating the impact of virtualized networking software (OPNET Network Simulator) on students' learning and motivation. 116 undergraduate students enrolled in a computer networking class at one of the universities in Egypt participated in this study, who were then randomly assigned to an experimental group (N= 59), which used the OPNET Network simulator, and a control group (N= 57) which studied the same content via the traditional physical lab. Two instruments; a networking test, and a Motivation Scale were administered to both study groups prior and post the intervention. Results showed that students of experimental group who used OPNET Networking simulator had significantly higher grades and greater motivation levels than those of the control group.
Contribution/ Originality
This paper's primary contribution is to find out how virtual learning environments can prove more effective than real environment on both learning and motivation. The current study came to this conclusion by employing a quasi-experimental method, while other studies relied mostly on anecdotal or tentative evidence.

Abstract
Students’ ESL writing skills in general are not at a desirable level. The objective of this study was to determine the effectiveness of utilizing the STAD method to enhance descriptive writing skills among students in an international school in Selangor, Malaysia. This study employed an action research design. The sample consisted of 20 Year 6 students aged between 11 and 12 years. The data for the research was obtained using a pre-test and a post-test, focus group interviews with students, teacher’s reflection and an observation checklist. The action-research was carried out over a period of 6 weeks. The quantitative data was analyzed using descriptive and inferential statistics and the qualitative data (interviews, teacher’s reflections and observations) was analyzed based on emerging themes. The findings from the quantitative data indicated that the STAD method helped to enhance students’ descriptive writing skills. The analysis of the qualitative data revealed that students enjoyed writing in groups and they stressed that they learned a lot from their friends when they wrote in groups. The teacher’s reflection revealed that the STAD method improved students’ writing skills through collaborative learning as they get the opportunity to edit their group essays. Findings from the observation showed that students were actively engaged in the process of writing during group work and their social skills improved too. This study has pertinent theoretical implications, pedagogical implications and practical implications in ESL writing.
Contribution/ Originality
This study is one of very few studies which have investigated the effectiveness of utilizing the STAD method to enhance students’ ESL writing skills in an international school. This study has strong pedagogical implications as it serves as a guide to teachers on how to carry out action research using the STAD method.

Abstract
This study examines the use of metadiscourse markers among 50 Malaysian and 50 Arab Pre-University students. The findings of this study indicated that there was a significant difference in the use of metadiscourse markers between Malaysian and Arab Pre-University students {?2 (1, n = 100) = 7.17, p-value is .007} where the use of metadiscourse markers among Malaysian Pre-University students was substantially higher than that of the Arab Pre-University students. In the use of interactive markers, the results showed significant differences between Malaysian and Arab Pre-University students in the use of transitions, evidential and code glosses. Additionally, in the use of interactional markers, Malaysian and Arab students differed in their use of hedges, engagement markers and self-mentions. These variances in the frequency and forms of metadiscourse markers utilized by the students could be attributed to the diverse cultural backgrounds of the two groups of students. It is therefore suggested that English language teachers integrate and incorporate cultural elements in their lessons with regard to metadiscourse markers.
Contribution/ Originality
This study documents the examination of metadiscourse markers employed by ESL students and this has offered interesting findings and thought-provoking insights. The discoveries would certainly be enlightening for stakeholders such as syllabus designers of academic writing classes and language instructors.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study applies the theory of Readiness for Organizational Change (Holt et al., 2007) with respect to the Learning Management System (LMS) such as Blackboard. Widely adopted in organizational environments, this theory discusses four types of antecedents: content, process, context and individual differences in order to determine behavioral patterns in change recipients. Based on prior studies, and modifying Holt et al’s model, this paper created a Model for Readiness for Acceptance of Change (MRAC) to meet the requirements of implementing the Blackboard LMS at Prince Sattam bin Abdulaziz University (PSAU), Saudi Arabia. This paper studied three variables: readiness for acceptance for change, change beliefs and resistance to change. 340 respondents, male and female, comprising Faculty and students PSAU from all schools and levels, participated in this study. A questionnaire was prepared to collect data. SPSS software was used to analyze the data. The results suggested that readiness or acceptance for change is a multidimensional variable influenced by factors such as context, change beliefs, individual differences and resistance to change. The results also suggested that respondents were aware of the usefulness of a change, their beliefs were stronger but they lacked readiness for that change.
Contribution/ Originality
This study shall contribute towards motivating Faculty and Students for adoption of Blackboard LMS. It will also provide useful insights to policy makers and university management to take initiatives for developing positive beliefs in Faculty and learners in order to develop Readiness for Change.

Industrialization and Economic Growth in Sub-Saharan Africa: The Role of Human Capital in Structural Transformation

Research Article
Author(s): Kwami Ossadzifo WONYRA
Journal: Journal of Empirical Studies

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The objective of this paper is to analyze the impact of the manufacturing sector on economic growth through the role of human capital. Our data cover Sub-Saharan African (SSA) countries from 1990 to 2015. We use fixed effects, random-effects and Hausman-Taylor estimators. We take into account the unobservable characteristics of countries by including fixed effects or random effects in the model. Our results show that the manufacturing sector through its value added has a positive impact on economic growth in SSA countries. In addition, the interacting models show that the quality of human capital is an accelerator of the role of the manufacturing sector. The coefficient of the catch-up term is negative and significant in all models indicating that countries with a larger productivity gap relative to China are developing faster than countries closer to China. This finding is consistent with the convergence effects usually found in growth model estimates, which are either related to convergences towards a stable state or to a catching-up of growth linked to the international diffusion of knowledge.
Contribution/ Originality
Unlike previous work, this article brings three major innovations. First, the inclusion of the key role of human capital, then the construction of the productivity indicator by considering China as a reference, and finally the consideration of the endowments of natural resources of countries in sub-Saharan Africa as country-specificity.

Research Article
Author(s): Tekam Oumbe Honore, Tchouassi Gerard
Journal: Journal of Empirical Studies

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This article shows that trade policy and democracy positively affect economic development. A panel of 11 Central Africa economies with 176 observations from 1995 to 2010 is used to econometrically test this hypothesis. The use of Generalised Least Squares (GLS) shows that there is a link between economic development, captured using Human Development Indicators (HDI), democracy, imports, exports, inflation and regional integration. Inflation and exports negatively affect the well-being of the population. An increase in the inflation rate causes a reduction in purchasing power. An increase in the exports of commodities tends to decrease the quantity of goods available for the country of origin. Imports have a positive effect on HDI probably because this variable tends to increase the quantity of goods available. Imports and democracy have a positive effect on the level of development in Central African countries. The findings are important to policy makers Central Africa who seek to increase trade within, between and with other democratic countries.
Contribution/ Originality
This study documents that trade policy and democracy contribute positively to economic development.

Abstract
Powders from five elite plant materials (nutmeg, Myristica fragrans; red hot chilli pepper, Capsicum annuum; ginger rhizome, Zingiber officinale; black pepper, Piper nigrum and alligator pepper, Aframomum melegueta) at 1.5 % w/w concentration were assessed against cowpea bruchid, Callosobruchus maculatus infestations on stored cowpea seeds under laboratory environmental conditions in three agro-ecological zones in Nigeria by members of the Research Group. The conventional synthetic insecticide, permethrin was included as standard check, while untreated seeds served as the control. Adult mortality, oviposition rate and adult emergence were the indices considered in the experiments. For the first three days of exposure, black pepper (P. nigrum) powder caused the highest percentage mortality (68.8, 78.0 and 83.8 % respectively) of the bruchid adults and differed significantly (P < 0.01) from the rest of other treatments with the exception of permethrin that caused 78.8, 85.0 and 91.3 % mortality respectively. Similarly, black pepper powder and permethrin treatments differed significantly (P < 0.01) from the rest on number of eggs laid and emerged adults with the exception of Z. officinale rhizome, which did not differ significantly from P. nigrum on number of eggs laid. The results therefore suggest that black pepper powder has higher insecticidal potential over other plant materials and could serve as a biotechnological substitute to the synthetic insecticides in the control of C. maculatus infestations and damage in stored products.
Contribution/ Originality
The paper’s primary contribution is finding that some bioinsecticides derived from medicinal plant materials could serve as substitute to the hazardous synthetic insecticides at economically justified concentration in the control of C. maculatus infestation and damage in stored cowpea seeds.

Research Article
Author(s): Muntasir Murshed
Journal: Journal of Tourism Management Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Tourism can somewhat be compared to the Cinderella industry, much because of its development being unattended despite having immense potentials in generating development within an economy. This paper aims to fill the gap in the literature by modeling tourist demand in Bangladesh as a function of its real fundamentals using time series data over the period 1980 to 2017. Augmented Dickey-Fuller (ADF) unit root tests along with the Autoregressive Distributed Lag (ARDL) bounds testing approach to cointegration and causality analyses are considered. The results reveal that the relative cost of living in Bangladesh and travel costs negatively affect international tourism demand while the relative cost of living in India, national income and exchange rate are found to be positively associated to tourism demand in Bangladesh. Moreover, long run causalities stemming from all the explanatory variables to tourism demand are also established in light of the statistical evidence found. Thus, it is pertinent for the government to escalate tourism development in Bangladesh which can also play a pivotal role in the diversification of the nation's export basket.
Contribution/ Originality
To the best of knowledge there is no empirical paper focusing on the international tourism sector of Bangladesh economy. This paper fills that gap by employing a multivariate framework to determine the demand side factors influencing tourism in Bangladesh.

Abstract
This study have examined the determinants of corruption in Nigeria's public sector using ten local government areas in Lagos State and Federal Capital Territory in Abuja during the period 2017-2018. Plethora of studies has analyzed the relationship between corruption and economic growth using different econometric techniques and statistical simulation. This study, however, departed from the common methodological approach by conducting a survey of corruption in public sector to ascertain its determinants. Findings from a survey of one thousand and seventy six (1976) subjects were documented and multiple variables emanated as critical determinants of corruption in public sector. The study recommends that policy makers should intensify efforts at re-orientating the society against the ills of corruption by establishing high ethical standards to which all and sundry must adhere.
Contribution/ Originality
This study contributes to the existing body of literature by adopting a survey technique to ascertain the determinants of corruption in Nigeria's public sector by exploring ten (10) local government areas in Lagos State and Federal Civil Service in Abuja. A large number of studies in this area have employed theoretically established and econometric expositions to validate the determinants of corruption. The study uses common statistical technique to analyze both the causal and determinate variables motivating corruption.

Journal: The Economics and Finance Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This work was set out to measure the responsiveness of foreign reserves to exchange rate variables with a focus on the Nigerian economy. Foreign reserve was used as a dependent variable and all the exchange rate related variables used as independent variables. Time series data spanning 1996 to 2016 was used. A combined use of the Auto Regressive Distributed Lag Model (ARDL) and correlation matrix were employed. It was found that a positively significant relationship exists between real exchange rate and reserves with nominal exchange rate sharing a positive but non-significant relationship with foreign reserves. This makes a case for proper policy direction in the management of exchange rate in a manner that produces the best economic results for the Nigerian economy. The results are considered useful for economies in the shape of Nigeria for generalization and policy direction in the management of foreign reserve and its interface with exchange rate and its related factors.
Contribution/ Originality
This study contributes to the existing literature by uncoupling exchange rate into nominal and real in measuring the nexus with foreign reserves. This study uses new estimation methodology which is the ARDL approach unlike prior studies that used OLS predominantly. The paper contributes the first logical analysis by carrying out pre-test, estimation proper and diagnostic analyses. The paper's primary contribution is that it exposes the fact that a nexus exists between foreign reserves and changes in exchange rate.

Abstract
Anxiety in the classroom presentation has a debilitating effect on students’ success in learning a foreign language (FL) or a second language (L2). This article aimed at investigating students’ Anxiety in classroom presentation in Teaching – Learning Interaction of English as a Foreign Language for Students of Indonesian Study Program in general at higher education levels in Indonesia. The participants of this study were the students of Indonesian Education and Literature Department, Faculty of Education and Literature, Universitas Negeri Makassar (N = 62). There were 55 or 88.71% females and 7 or 11.29% males from the seventh (42 or 67.75%) and ninth (20 or 32.25%) semesters. The findings reveal that the most frequent source of students’ anxiety was attending disorganized classroom presentation. The implication of the study is that anxiety is an interesting phenomenon in language study which potentially contributes to students’ failure. Therefore, teachers at a school need to manage the class well, while the lecturers at the university need to give a lot of time for students to learn the topics for discussion.
Contribution/ Originality
This study contributes to the existing literature on Anxiety in classroom presentation in teaching - learning interaction in English as a Foreign Language in Indonesia. As one of contributing factors to classroom low achievement, Anxiety syndrome needs to be understood by teachers and learners at the university.

Abstract
This study aims to examine employers’ expectations of knowledge and skills in accounting graduates before hiring them. Using a qualitative approach on accounting practitioners and academics, this study shows that the expectations employers place on accounting students in the Industry 4.0 environment is set to change significantly, particularly in technologies used in the preparation, reporting and dissemination of financial information. Specifically, this study showcases the strong views expressed by a panel of experts comprising accounting practitioners, particularly on the subjects of job redundancies and the degree of replacement of human activities by electronic devices and machines. The replacement of physical human activities by machines is therefore expected. In addition, accounting practitioners see the need for accounting graduates to focus on continuous learning and education, particularly in acquiring knowledge and skills in IT. Hence, there is a need for academics and universities to incorporate various accounting technologies and simulations that are applicable to the Industry 4.0 environment, in their teaching and learning activities. This study contributes to existing education literature by providing new findings on the expectations of employers of future accounting graduates. In addition, this study contributes to the further understanding of academics and universities in strategizing ways and innovating new teaching and learning approaches so that accounting graduates’ employability can be enhanced and the needs of the current market for accountants can be accommodated.
Contribution/ Originality
This study is the first to provide findings on the expectations of employers of future accounting graduates in the era of Industry 4.0 in a Malaysian context.

Abstract
Preservatives have been frequently used to improve the shelf life of food. The preservation of eggplants was determined using three chemical preservatives; ascorbic acid, sodium benzoate and sodium metabisulphite applied at different concentrations. The microbial load was determined to ascertain the efficacy of the preservatives. The microbiological population and diversity of the eggplant was assessed before and after treatment using standard methods. The plate count techniques was adopted to determine the total colony forming unit of the sample. Antimicrobial activities revealed that sodium benzoate inhibits the growth of bacterial and fungal species even at low concentration. Sodium metabisulphite was effective on bacteria while ascorbic acid showed a stimulatory response on the growth of fungi and bacteria. Four bacteria species namely, Staphylococcus aureus, Bacillus subtilis, Micrococcus luteus and Enterococcus faecalis and four fungal species, namely, Saccharomyces, Fusarium, Aspergillus and Rhizopus were isolated. Most of the isolates are soil and water borne which could serve as vehicle for contamination of the eggplants. Some of the isolates like Staphylococcus and Bacillus are involved in food spoilage and borne infections while Aspergillus and Fusarium species are notable causes of mycotoxicoses in man and animals. This study shows that preservatives applied at appropriate concentrations can create adequate protection from spoilage microorganisms, and therefore recommends the use of sodium benzoate to enhance the keeping quality of eggplants.

Abstract
In this study, the prediction issue of oil viscosity, on oil samples taken from Guneshli oil field of Azerbaijan has been viewed applying empirical correlations as Beggs-Robinson, Labedi, modified Kartoatmodjo, Elsharkawy and Alikhan, Al-Khafaji. The correlation models used in the evaluation of viscosity of Azerbaijan oil have been implemented in the Python software environment. The obtained values on empirical correlations have been compared to experimental data obtained from Guneshli oil field. The result of prediction has been evaluated using statistic functions as absolute average deviation (AAD), mean absolute error (MAE), correlation coefficient, root mean square error (RMSE). According to statistical analysis, it has been known that the Beggs-Robinson model has shown the lowest value on AAD (10.5614%), MAE (12.4427 %), RMSE (20.0853 %). The Labedi model has presented the worst result on every four criterions. Even though the Elsharkawy-Alikhan model has presented the highest result (99.9272%) on correlation coefficient, in the evaluation of viscosity of Azerbaijan crude oil, the Beggs-Robinson model can be considered more acceptable.

The study had a sample size of 136 obtained using the Cochran statistical formula. The study employed a survey research design. The instrument used for data collection was the questionnaire. The data from the responses were presented in frequencies, simple percentages. Three hypotheses were tested using the chi-square X2 and t-test statistical tools. The study found out that: Employee participation in decision making significantly improves job productivity (X2 cal = 2.554 > X2 0.5 = 0.6763); employee participation in decision, making relates to employee motivation (Fc – test = 21 .56 > ft 1 = 2.01); the policy of employee participation in decision-making is significant in organizational goal attainment (X2 Cal = 1.887 > X2 0.5 = 0.6763) The study, based on the above findings, concluded that for the goal attainment of any organization to be achieved successfully depended on the extent to which the organization integrated the workers into the policy formulation and implementation. The study recommends that organizations should adopt the ring show management theory as a way of survival.
Contribution/ Originality
This study is one of the very few studies which have investigated employees’ participatory decision making and organisational goal attainment. Currently there are paucity studies in Abuja that examine organisational goal attainment. This study contributes an important additional dimension in the search for sustainable organisational goal attainment in Nigeria.

Abstract
The current research presents corrosion inhibition activity of expired Fluoxymesterone drug on the mild steel (MS) in the 3 M HCl solution. The atomic absorption spectroscopy, Tafel polarization and AC impedance spectroscopy studies have been done to verify the corrosion protection efficiency. The surface studies were carried out by scanning electron microscopy (SEM) technique. Atomic absorption spectroscopy results show that, the amount of iron content is low in the presence of corrosion inhibitor when compared with bare system. Tafel plots clearly hint the mixed corrosion inhibition property (inhibition of both anodic and cathodic corrosion process) of expired Fluoxymesterone drug over the MS surface in the acidic environment. From the AC impedance spectroscopy technique, it is observed that, the charge transfer resistance values enhances with a rise in the concentration of the corrosion inhibitor. Surface studies by SEM also support the atomic absorption spectroscopy, potentiodynamic polarization (Tafel plot) and AC impedance spectroscopy results.
