Investigating the Challenges Facing the Teaching and Learning of Science and Technology in Selected Schools in the Ashanti Region of Ghana

The heightening public apprehension about instructional deliveries and the learning of science in Ghanaian schools have taken a different dimension as many shareholders keep interrogating the Government's pledge to ensure equity and quality science education for primary schools in the country. The study explored and defined the standing and quality of teaching, learning, and assessment of science and technology while finding the challenges faced by science educators at the JHS level in selected schools in the Ashanti region. The study randomly sampled science teachers' views and students in 27 schools from the 27 districts in the Ashanti Region in Ghana. Fourteen (14) and thirteen (13) schools were sampled from rural and urban areas. It was found that Government inadequately funds most schools. As a result, few qualified science teachers can handle the integrated science topics, among many other setbacks. It was concluded that the lack of infrastructure, TLMs, and other factors make the teaching and learning of science practically impossible. These challenges can be mitigated when specific, well-defined measures such as the provision of required infrastructure, teaching, learning materials (TLMs), and a few more are urgently implemented

Education and Employment Outcomes in Ghana through the Lens of the Capability Approach

Existing literature on education and employment confirms that in Ghana educational qualification largely influences the type of work. Through the lens of the Capability Approach, which sees human development in terms of the expansion of freedoms and opportunities, this paper identifies, for a cross-section of Ghanaians, the array of employment opportunities between and within education endowments. “Between endowments” refers to differentials in opportunities for individuals with different levels of educational qualifications, while “within endowments” considers the differentials for individuals with the same level of education. The source of data is the 2005/06 Ghana Living Standard Survey (GLSS5). Results show that education is not enough to erase inequalities. Multinomial regression analysis demonstrates that functionings differ according to the individual’s context, household and personal conversion factors. This is explained by inequalities in the requirements for a particular job (between educational endowments) and by job accessibility due to personal characteristics (within educational endowments)

Foreword

The globalization process constantly spawns new ideas, and researchers are generally willing to share and adapt them. It can be recalled that UNDP report no. 1/1990 saw the basic objective of human development as the enlargement of the range of people’s choices, which are not fixed forever. There have been many approaches to the study of human development. For instance, Classical Economics measures human development using the size of a country’s GDP or per capita income. The Welfare Approach uses income and consumption. The Utilitarian Approach focuses on happiness, good and pleasure, while the Basic Needs Approach measures access to water, shelter, food and sanitation, among others. It is impressive that, just ten years later, Amartya Sen managed to pull all these ideas together into a single framework called the Capability Approach. This new concept of measuring human development focuses on freedom as development. Although nowadays widely known, the Capability Approach is still rarely used in population studies and policies, and this is especially true for Africa. This volume is therefore welcome, but in addition it is timely, and this for at least two reasons

The Local Food Environment and Body Mass Index among the Urban Poor in Accra, Ghana

Obesity in the sub-Saharan Africa region has been portrayed as a problem of affluence, partly because obesity has been found to be more common in urban areas and among the rich. Recent findings, however, reveal rising prevalence among the poor particularly the urban poor. A growing body of literature mostly in Western countries shows that obesity among the poor is partly the result of an obesogenic-built environment. Such studies are lacking in the African context. This study examines the characteristics of the local food environment in an urban poor setting in Accra, Ghana and further investigates the associated risk of obesity for residents. Data on the local food environment was collected using geographic positioning system (GPS) technology. The body mass indices (BMI) of females (15-49 years) and males (15-59 years) were calculated from measured weight and height. Data on the socio-demographic characteristics and lifestyle behaviors of respondents was also collected through a household survey. Spatial analysis tools were used to examine the characteristics of the local food environment while the influence of the food environment on BMI was examined using a two-level multilevel model. The measures of the food environment constituted the level 2 factors while individual socio-demographic characteristics and lifestyle behaviors constituted the level 1 factors. The local food environment in the study communities is suggestive of an obesogenic food environment characterized by an abundance of out-of-home cooked foods, convenience stores, and limited fruits and vegetables options. The results of the multilevel analysis reveal a 0.2 kg/m(2) increase in BMI for every additional convenience store and a 0.1 kg/m(2) reduction in BMI for every out-of-home cooked food place available in the study area after controlling for individual socio-demographic characteristics, lifestyle behaviors, and community characteristics. The findings of this study indicate that the local food environment in urban poor Accra is associated with increased risk of obesity through providing access to convenience stores. In order to reduce the risk of obesity in these urban poor communities, there is the need to regulate the availability of and access to convenience stores while also encouraging healthier offerings in convenience stores

“Shaping the family”: Individual’s capabilities to exercise reproductive rights seen through a qualitative survey

We analyze here the outcome of focus group discussions and individual interviews conducted in Mali and Ghana. The aim is to identify collective images about family norms and emergence of alternative values, and to examine people’s degree of ambivalence towards norms and their ability to conceive and realize their own family plans. Discourses show that family life plans should not be seen as pre-established. Ability to shape the family appears conjectural both as regards current resources and the position in the family trajectory. In both countries, two types of resources play a key role: schooling and influence/support from the family and network. Results highlight that the least individual freedom is to be found at the start of family life and in gender power relationships; some freedom appears in the timing of fertility; while more room for individual agency characterizes youth and individuals with more personal resources and supportive surroundings

Within-Neighborhood Patterns and Sources of Particle Pollution: Mobile Monitoring and Geographic Information System Analysis in Four Communities in Accra, Ghana

BACKGROUND: Sources of air pollution in developing country cities include transportation and industrial pollution, biomass and coal fuel use, and resuspended dust from unpaved roads. OBJECTIVES: Our goal was to understand within-neighborhood spatial variability of particulate matter (PM) in communities of varying socioeconomic status (SES) in Accra, Ghana, and to quantify the effects of nearby sources on local PM concentration. METHODS: We conducted 1 week of morning and afternoon mobile and stationary air pollution measurements in four study neighborhoods. PM with aerodynamic diameters RESULTS: In our measurement campaign, the geometric means of PM2.5 and PM10 along the mobile monitoring path were 21 and 49 microg/m3, respectively, in the neighborhood with highest SES and 39 and 96 microg/m3, respectively, in the neighborhood with lowest SES and highest population density. PM2.5 and PM10 were as high as 200 and 400 microg/m3, respectively, in some segments of the path. After adjusting for other factors, the factors that had the largest effects on local PM pollution were nearby wood and charcoal stoves, congested and heavy traffic, loose dirt road surface, and trash burning. CONCLUSIONS: Biomass fuels, transportation, and unpaved roads may be important determinants of local PM variation in Accra neighborhoods. If confirmed by additional or supporting data, the results demonstrate the need for effective and equitable interventions and policies that reduce the impacts of traffic and biomass pollution

Prenatal Household Air Pollution Exposure, Cord Blood Mononuclear Cell Telomere Length and Age Four Blood Pressure: Evidence from a Ghanaian Pregnancy Cohort.

Associations between prenatal household air pollution exposure (HAP), newborn telomere length and early childhood blood pressure are unknown. Methods: Pregnant women were randomized to liquefied petroleum gas (LPG) stove, improved biomass stove or control (traditional, open fire cook stove). HAP was measured by personal carbon monoxide (CO) (n = 97) and fine particulate matter (PM2.5) (n = 60). At birth, cord blood mononuclear cells (CBMCs) were collected for telomere length (TL) analyses. At child age four years, we measured resting blood pressure (BP) (n = 97). We employed multivariable linear regression to determine associations between prenatal HAP and cookstove arm and assessed CBMC relative to TL separately. We then examined associations between CBMC TL and resting BP. Results: Higher prenatal PM2.5 exposure was associated with reduced TL (β = -4.9% (95% CI -8.6, -0.4), p = 0.03, per 10 ug/m3 increase in PM2.5). Infants born to mothers randomized to the LPG cookstove had longer TL (β = 55.3% (95% CI 16.2, 109.6), p < 0.01)) compared with control. In all children, shorter TL was associated with higher systolic BP (SBP) (β = 0.35 mmHg (95% CI 0.001, 0.71), p = 0.05, per 10% decrease in TL). Increased prenatal HAP exposure is associated with shorter TL at birth. Shorter TL at birth is associated with higher age four BP, suggesting that TL at birth may be a biomarker of HAP-associated disease risk

Infant Nasopharyngeal Microbiota Subphenotypes and Early Childhood Lung Function: Evidence from a Rural Ghanaian Pregnancy Cohort.

Early life respiratory microbiota may increase risk for future pulmonary disease. Associations between respiratory microbiota and lung health in children from low- and middle-income countries are not well-described. Leveraging the Ghana Randomized Air Pollution and Health Study (GRAPHS) prospective pregnancy cohort in Kintampo, Ghana, we collected nasopharyngeal swabs in 112 asymptomatic children aged median 4.3 months (interquartile range (IQR) 2.9, 7.1) and analyzed 22 common bacterial and viral pathogens with MassTag polymerase chain reaction (PCR). We prospectively followed the cohort and measured lung function at age four years by impulse oscillometry. First, we employed latent class analysis (LCA) to identify nasopharyngeal microbiota (NPM) subphenotypes. Then, we used linear regression to analyze associations between subphenotype assignment and lung function. LCA suggest that a two-class model best described the infant NPM. We identified a higher diversity subphenotype (N = 38, 34%) with more pathogens (median 4; IQR 3.25, 4.75) and a lower diversity subphenotype (N = 74, 66%) with fewer pathogens (median 1; IQR 1, 2). In multivariable linear regression models, the less diverse NPM subphenotype had higher small airway resistance (R5-R20 β = 17.9%, 95% CI 35.6, 0.23; p = 0.047) compared with the more diverse subphenotype. Further studies are required to understand the role of the microbiota in future lung health
