Ethical Leadership and Employee Creativity Among Engineering Employees: Evidence From a Developing Economy
(Benchmarking: An International Journal, 2023-03-31) Tetteh, Stephen; Mensah, Dei Rebecca; Opata, Narh Christian; Mensah, Nyarko Claudia
Purpose– Based on the trait activation theory, the current study systematically integrates how autonomy interacts with proactivity to influence the relationship between ethical leadership style and employee creativity. Design/methodology/approach– Using simple random sampling and questionnaires, a sample of 475 engineering employees of 3 leading telecommunication companies in Ghana were obtained. The analysis was done using structured equation modeling (SEM), using Smart PLS. Findings– The results showed that ethical leadership style provides employees with job autonomy which facilitates individual creativity. Employee proactivity also moderates a positive relationship between autonomy and creativity such that high-proactive employees are well placed to produce more creative outcomes when given autonomy. At the individual level, personal characteristics determine the degree of creativity. Practical implications– The current study implies that telecommunication companies should put in more efforts to train and encourage leaders to be ethical in leaders’ dealings with employees and employees must be rewarded for taking initiative. Originality/value– With a focus on the integrative approach from a developing economy, this work is novel in exploring how contextual and personal features impact creativity.
Enhancing TVET students’ interest in mathematics through the history of mathematics and self-efficacy
(Journal of Applied Research in Higher Education, 2024-12-01) Arthur, Yarhands Dissou; Vittori, Thomas De; Welcome, B. Natalie; Dogbe, Courage Simon Kofi; Asare, Bright
he history of mathematics (HIST) and the interest in mathematics. Design/methodology/approach – A survey research design was adopted, with a quantitative research approach. The study adopted a convenience sampling technique to select 219 Technical and Vocational Education and Training (TVET) students (level 100 to 400) from a public university in Ghana. Structural equation modelling (SEM) and a bias-corrected percentile method of bootstrapping were run in AMOS (v. 23), to estimate the path coefficients. Findings – The study found that the HISTsignificantly influences both the student’sinterest in mathematics and their mathematics self-efficacy. Furthermore, mathematics self-efficacy was found to significantly affect students’ interest in mathematics and partially mediate the relationship between the HISTand students’ interest. Research limitations/implications – The study was confined to TVETstudents in a single public university in Ghana. Future studies may consider TVET students in other disciplines in other universities within or outside Ghana to increase generalization. Originality/value – There is a shortage of empirical studies that specifically examine how self-efficacy mediatesthe relationship between the HISTas a teaching tool and students’ interest in mathematics. Also, while previous studies have examined the role of pedagogical approaches in mathematics education, there is a lack of research focusing on the impact of historical context on students’ interest, particularly within TVET settings.
Inclusive Pedagogies in Mathematics Education: Experiential Learning for Deaf Learners in Specialized Settings
(American Journal of STEM Education: Issues and Perspectives Star Scholars Press, 2025) Hatsu, Edo; Boateng, Francis Ohene; Arthur, D. Yarhands; Akosah, Ernest Frimpong
In this paper, we examined the effects of experiential learning combined with collaborative teaching on the mathematics achievement of deaf learners in specialized classrooms. A quasi-experimental design was employed, comparing pre-test and post-test scores of a control group that received traditional instruction with those of an experimental group taught through experiential learning using collaborative methods. Both groups showed improvement, but the experimental group demonstrated significantly greater gains. Findings confirm the effectiveness of learner-centered approaches in enhancing engagement and understanding among deaf students. The study aligns with global education reform efforts that advocate for inclusive, adaptive teaching practices. It highlights the importance of 98 innovative pedagogies in addressing diverse learner needs and promoting equitable outcomes, particularly in specialized and cross-cultural educational settings.
Optimizing High School Mathematics Achievement through the Lens of Realistic Mathematics Education: The Mediating Role of Teacher Self-Efficacy
(International Journal of Studies in Education and Science (IJSES), 2025) Akosah, Ernest Frimpong; Arthur, Yarhands Dissou; Obeng, Benjamin Adu
This study examines the relationship between teaching quality, teacher self efficacy, and students' mathematics achievement among junior high school students in Ghana, utilizing Realistic Mathematics Education and Self Determination Theory as frameworks. A stratified purposive sample of 507 junior high school mathematics teachers from eight regions was selected, employing a correlational cross-sectional survey design. Structural Equation Modeling (SEM) tested the hypotheses that teaching quality positively affects mathematics achievement, teacher self-efficacy influences teaching quality, and self-efficacy mediates the relationship between teaching quality and achievement. Results confirmed that high-quality teaching significantly improves mathematics achievement, especially when contextualized with RME principles. Teacher self efficacy emerged as a critical factor in enhancing teaching quality and directly influencing student outcomes. Mediation analysis showed that teacher self efficacy strengthens the effect of teaching quality on achievement. These findings highlight the need for educational policies to focus on professional development that boosts teachers' efficacy and promotes realistic, student-centered instructional strategies.

These results provide key insights for educational policy and instructional strategies aimed at improving learning outcomes through technology
Effects Of Mother Tongue Instruction On Students’ Mathematical Achievement In The Bekwai Municipal
(Education & Learning in Developing Nations (ELDN), 2024-04-08) Abdul-Ganiyu, Fuseini; Obeng, Benjamin Adu; Asare, Bright; Arthur, Yarhands Dissou
The study examined the effect of the mother tongue teaching on students' mathematical achievement. From St. Joseph Senior High Technical School, two experimental classes and one control class were chosen. While the control group was instructed only in English, the first experimental group was instructed exclusively in their native language (Twi), whereas the second experimental class was instructed using mother tongue (Twi) as an additional medium of instruction. The results of the pre-test and post-test were statistically examined using the t-test. The findings showed that using Twi as the sole teaching language and using English as the only training language were equally unsuccessful, while mother tongue (Twi) was found to be statistically significant in improving students’ mathematics achievement.
The Mediating Role of Teacher Effective Communication on the Relationship between Students’ Mathematics Interest and their Mathematics Performance
(International Journal of Mathematics and Mathematics Education, 2024-12) Akendita, Paul Agmabire; Boateng, Francis Ohene; Arthur, Yarhands Dissou; Banson, Gideon Mensah; Abil, Maccarthy; Ahenkorah, Marfo
The study investigated how teacher-effective communication mediated the relationship between students’ mathematics interest and performance. The descriptive survey design, which is anchored on the quantitative research approach of the positivism paradigm, was used, and 200 second-year students of a Senior High School in the Talensi district of the Upper East Region were selected through the means of stratified sampling procedures as well as random selections from the strata. A structural equation model (SEM) with bootstrap samples was used to analyze the gathered data, and it was discovered that students' performance in mathematics was positively and statistically impacted significantly on their interest in the subject. In addition, teacher-effective communication was found to have a significant direct positive statistical effect on students’ mathematics performance. Furthermore, students’ mathematics interests correlated positively with the teacher's effective communication. The findings indicated that there existed a partial mediation effect of teacher-effective communication on the relationship between students’ mathematics interest and students’ mathematics performance. Teachers should be allowed to grow professionally in teaching mathematics to communicate vividly and efficiently in mathematical concepts. This will strengthen their mathematical communication skills and also imbibe in them the abilities to incorporate different kinds of collaborative learning techniques to aid students in making faster progress in their mathematical proficiency.
Innovation, Trade Openness and CO2 Emissions in Selected Countries in Africa
(Journal of Cleaner Production, 2020-11-16) Dauda, Lamini; Xingle, Long; Mensah Nyarko ,Claudia; Salman, Muhammad; Boamah, Baah Kofi; Ampon-Wireko, Sabina; Dogbe, Simon Kofi Courage
Innovation is considered an effective tool for fighting CO2 emissions as it enhances energy efficiency and cleaner production. However, it has received limited attention in the context of Africa. Therefore, the study examines the nonlinear link between innovation and CO2 emissions in nine (9) African nations from 1990-2016 at both panel and individual country level. The cross sectional augmented Dickey Fuller (CADF) panel unit root test affirmed the stationarity of the variables. Westerlund and Johansen cointegration tests established a long-run link amongst the variables. The study employed fixed effect model and generalized method of moments for the panel and ordinary least square for individual country. The results validated an inverted U-shape relationship between innovation and CO2 emission at panel level and in Mauritius, Egypt, and South Africa. Renewable energy use lessens CO2 emissions at the panel level. Human capital decreases CO2 emissions at the panel and in some individual countries. Moreover, both pollution haven hypothesis and pollution halo effect were confirmed. Similarly, at the panel level Environmental Kuznets Curve was confirmed in 4 out of 9 countries. Our findings suggest that regional integration and assimilation of innovation into all stages of development for green growth should be pursued.

The study examined the perception of Management Students towards Management Educational Programme (MEP) in the Faculty of Business Studies Education, College of Technology Education, University of Education, Winneba. The study adopted the quantitative research approach through the multi-stage sampling technique to sample 300 management students from the College of Technology Education. Data was analyzed through the use descriptive statistics, Pearson correlation, regression and rank order analysis. The result showed overall positive perception of students towards the educational management programme as each indicator was significant (PUM: p < 0.05). On individual cases, the average values showed that “MEP” has enhanced my leadership qualities” was the most positively perceived statement for respondents. The result indicated a strong positive correlation between Perceived Usefulness of Management Programme and learning outcome/performance (.853, p< 0.001; .850, p < 0.05). Further, the study found that Perceived Usefulness of Management Education Programme strongly predicted students’ performance or learning outcome. The study found that motivation plays a vital role in teaching and learning. Technology utilization and inadequate instructional materials are fundamental challenges that impacted on teaching and learning. The study concluded that the programme has the potential of providing the needed skills, values, attitudes and behaviors needed to meet the national goals as well as developing innovative and knowledgeable students with basic managerial and administrative skills for the world of work.
Is recapitalisation regulation a disrupter? Survival and sustainability of indigenous Ghanaian banks
(Qualitative Research in Financial Markets ©EmeraldPublishingLimited, 2022-01-07) Takyi, lydia; Naidoo, Vannie
Purpose– This study aims to explore how the implementation of the recapitalization by the Bank of Ghana disrupted the indigenous banks’ sources of accessing capital to raise the required amount within the mandatory stipulated time/deadline. Design/methodology/approach– This study used purposive sampling techniques to interview key role players and senior members involved in the bank’s recapitalization process and/or have in-depth information onthe2017–2018 recapitalization period. Findings– This study revealed that government directives significantly shape banks regulations and strategy: accordingly, any state-directed policies must be communicated cautiously, well explained and implemented to reduce any negative consequences. Originality/value– This study makes a significant contribution to knowledge by exploring how directives (arbitrary) of regulatory bodies can influence the business as well as its other stakeholders (such as the depositors, public, among others). Secondly, the study highlights how the delays in government support may not derive the benefits expected by the regulator.
Annual Household Budget Share in Formal Education Expenditure Using the Ghana Living Standards Survey Round Six Data: A Micro-Level Statistical Investigation
(Elsevier, 2024) Addai, Isaac
Using household-level data from the Ghana Living Standards Survey Round Six, this paper focused on examining factors that determine annual household expenditure on formal education in Ghana, using the annual share of household budget in total education expenditure as the dependent variable. The study established that households in Ghana spend an average of 5.6 percent of their annual income on basic education, and the estimated ordinary least squares (OLS) effect shows that rural households spend 6.7 percent less on education than urban households in Ghana. Policy wise, the central government of Ghana must take measures to ensure that household spending on basic education is reduced more and concerted efforts purposefully upgrading infrastructure and human resources in rural areas to a much level comparable to that in urban areas, and annual rural household education expenditure would also see a tangible increase, ceteris paribus, in Ghana.
An Empirical Analysis of Ashanti Region Annual Household Education Expenditure Using the Ghana Living Standards Survey Round Six Data
(Elsevier, 2024) Addai, Isaac
Using data from the 2013 Ghana Living Standards Survey Round Six (GLSS VI), this paper analyses regional variables affecting regional household spending on education using the Tobit model. The results showed that households in the Ashanti region increased their education spending on all the four types of the education categories namely; basic education, secondary education, post-secondary education, tertiary education with the basic education expenditure accounting for 53% of households' education spending. To the author’s knowledge, this is the first study on the Ashanti region of Ghana to analyse the determinants of private education spending using data from the 2013 Ghana Living Standards Survey. This paper was unable to identify several other important factors that determine household spending on education in the Ashanti region because the GLSS VI data were not configured to examine these variables. 53% of Ashanti's private household spending on education goes only to basic education, which is worrying because it undermines the Education for All initiative being promoted by UNESCO.
A Micro-Level Empirical Analysis of Annual Household Food Budget Shares in Ghana
(Elsevier, 2024-02-05) Addai, Isaac
This study examines Ghana's annual household food expenditures and their Engel food curve using data from the 2017-2018 seventh round of the Ghana Living Standards Survey, which covered 14,009 household and lasted for one-year. Household demographics and specific variables influencing annual household food budget decisions in Ghana were examined, including income, household size, educational status of household head, household location, and household connectivity to electricity. The study establishes an inverse relationship between the share of the household food budget and the increase in household income, and a high annual household food expenditure elasticity with 0.49 pesewas out of every one cedi serving as an annual household marginal food budget share in Ghana, on average and ceteris paribus. The study provides additional statistical evidence that characterizes food as a necessity in Ghana and placed the country in the medium food insecurity zone. Economic development in Ghana means achieving food security at all times, which calls on the country to redouble its efforts to meet SDG Goal 2.
Analysing household expenditure on education in Ghana: An update
(Elsevier, 2023) Addai, Isaac
The study analysed household-level data derived from the latest GLSS VII collected as part of a 2016-2017 national survey in Ghana and focused on examining households' annual expenditure on education. The driving force behind this study was the lack of an empirical analysis of household spending on education using this most recent data. The study results are that an increase in annual household income of 100 cedis per year increases actual household expenditure on education by about 26 cedis. Households in the Savannah Zones in Ghana show positive annual expenditure on education, while the Forest and Accra Zones show negative correlations with education expenditure. The positive education budgets of rural households have the potential to bridge an unequal society, as rural students' access to education leads to greater inequality in the production of specialized human capital in Ghana and this is a significant finding. And policy-makers in Ghana must take pragmatic steps to drastically reduce the 36 percent of households that do not spend on education as a public education policy measure to achieve SDG4.
Performance and Efficiency Analysis of Public Polytechnic Institutions in the Academic Year of Transition to Technical Universities in Ghana
(Elsevier, 2024) Addai, Isaac
Purpose: The paper investigates the production and efficiency of 10 public polytechnic institutions multi-production in their transition to public technical universities in the 2015-2016 academic year in Ghana. Design/methodology/approach – Data Envelopment Analysis (DEA), a linear programming model, is applied to study the relative multi-production efficiency of the polytechnic institutions. Findings – The paper established that 50% of the public polytechnic institutions must continue to expand the enrolment of students into their programmes once they have transitioned into technical universities, since they enjoy economies of scale in their multi-productions and there are potential gains through efficiency. Research limitations – The research findings are stated with caution, given the small average size of public polytechnics in terms of Full-Time Equivalence student numbers. Practical implication – Matching inputs and outputs data for polytechnic institutions as higher education institutions (HEIs) to evaluate their efficiency and to encourage benchmarking as a means of improving performance in the academic year transiting them into public technical universities and beyond in Ghana, is thus welcome and unique and responds appropriately to the AU Agenda 2063 calls for evaluating the efficiency of higher education institutions on the continent. Social implication- The paper addressed a significant gap in the current public higher education literature in Ghana. Originality – To the author's knowledge, this is the first study using original data allowing analysis of multi-product efficiency in the 10 public polytechnic institutions in Ghana before their transition to public technical universities.
TARIFF REFORMS, FOOD PRICES, AND CONSUMER WELFARE IN GHANA DURING THE 1990S
(2011) Ackah, Charles; Oladeji, S.I. and Abiodun, Adewale Adegboye; Oduro-Mensah, Daniel; Tawiah, E.O.; Dodoo, Naa Dodua; Addai, Isaac; Tetteh, Peace Mamle; Kpoor, Albert; Amoakohene, Margaret Ivy; Biveridge, Fritz
In this paper, we analyse the effect of food price changes on household consumption in Ghana during the 1990s and assess the extent to which changes can be explained by trade and agricultural policy reforms. The measurement of the total household welfare effect, one that jointly considers first order effects as well as consumption responses, is the object of this study. Food consumption behaviour in Ghana is analyzed by estimating a complete food demand system using the linear approximate version of the AIDS model with household survey data for 1991/92 and 1998/99. The estimated price elasticities are then utilized to evaluate the distributional impacts of the relative food price changes in terms of compensating variation. The results indicate that the distributional burden of higher food prices fell mainly on the urban poor.
The Predicaments of Non-Residential Students in Ghanaian Institutions of Higher Education: A Micro-Level Empirical Evidence
(IISTE. No 1 Central, Hong Kong Island, Hong Kong SAR, 2015) Addai, Isaac
This paper in the field of capacity building and students’ affairs used the external survey assessment techniques of the probit model to examine the predicaments of non-resident students of the College of Technology Education, University of Education, Winneba. Considering the very limited residential facilities and the growing demand for tertiary education, being a tertiary residential student is gradually becoming a mirage in most Ghanaian public universities. This paper argued that the College of Technology Education, either through direct provision or indirectly through private providers, should take all steps to ensure that future non-residential student housing projects are conceived as an integral part of the academic community by taking direct and pragmatic steps to mitigate against the difficulties and problems non-resident students encounter at their various places of residence.
An Empirical Analysis of Gender Earnings Gap in the Ghanaian Informal Sector Using the 1998/1999 Ghana Living Standards Survey
(2011-07-30) Addai, Isaac
This study used the 1998/1999 Ghana Living Standards Survey (GLSS 4), a new nationally representative survey carried out by the Ghana Statistical Service (GSS) and applied the Oaxaca (1973) decomposition to empirically analyse the phenomenon of gender gap in earnings in the informal sector labour market. The findings suggest the existence of discrimination in gender earnings in the Ghanaian informal sector labour market, and that females in the Ghanaian informal sector labour market are on average and ceteris paribus more skilful by 36%. However, males having sample average female characteristics earn on average and ceteris paribus 87% more in log monthly wages than their female counterparts.
