There have been few studies on topic difficulty in the public administration curriculum of African universities. This is further problematized by non-existent literature on the relationships between gender, future career interest and country of study on student difficulty in the study of public administration. This is a gap in the public administration literature which this study attempts to fill. The work is significant to the extent that our understanding of ‘where the shirt tights’ regarding topics that students find difficult will guide teachers and other stakeholders in applying appropriate remedies. The purpose of the study is to find out (a) what topics in public administration students find difficult to learn; (b) if there are statistically significant relationship between gender and concept difficulty in the study of public administration in African universities; (c) if there are statistically significant relationship between student’s career interest and concept difficulty in the study of public administration; and (d) if there are statistically significant relationship between country of study and concept difficulty in the study of public administration. Quantitative method was employed with sample (N = 650). The study reports bureaucracy, decentralization, public policy and politics as moderately difficult; significant relationship between gender and concept difficulty; and significant relationship between student future career interest and concept difficulty. We suggest curriculum development that would improve students’ knowledge by laying more emphasis on the perceived difficult areas in the study of public administration, gender, and encourage early students’ interest in public sector career choices.
This paper provides glimpses of transactions in chemistry classrooms in five African countries (Burundi, Ghana, Morocco, Nigeria, and Senegal) during the COVID-19 lockdown. Members of the secondary school community in the countries including teachers, students, and school managers were unprepared for the unprecedent demand in shift from a face-to-face to an online delivery system. From a tepid, faltering start in the early days of the lockdown in Morocco, Nigeria, and Senegal, and recognizing that the end of the lockdown may not be in sight, some minuscule progress is being made in exploring virtual delivery of the chemistry curriculum. Four major challenges to online delivery of chemistry education emerged. These are a teacher capacity deficit for delivering online education, poor internet service, an erratic power supply, and severe inadequacies in infrastructure for open and distance education. Taken together along with poor teacher motivation induced by low and irregular wages, these challenges are depressants to quality chemistry teaching during the COVID-19 period. We foresee that these challenges will persist. The harsh effect of COVID-19 on the economy of all African countries is a sign that funds will be unavailable to address these challenges in the near future. A glimmer of hope can be the reprioritization of funding resources by African governments to online delivery of education, noting that blended learning will be the new normal in the coming decades.
This study described the implementation procedure (step-by-step) of the culturo-techno-contextual approach (CTCA) in the classroom with concrete curricular examples for each step. The study then proceeded to explore the potency of CTCA on nuclear chemistry, a traditionally perceived difficult concept among secondary school students in Nigeria, as obtained from the survey phase of the study. Using a quasi-experimental research design, we had a total of 221 senior secondary school two (SS2, the equivalent of grade 11) students from two schools in educational district V of Lagos State, Nigeria, who participated in the experimental phase of the study. After the pretest exercise for both the experimental and comparison groups, we had a four-week treatment where the experimental group was taught with CTCA, and the comparison group was taught with the conventional lecture method. Four weeks after the posttest, a retention test was conducted for both groups using the same Nuclear Chemistry Achievement Test instrument used for the pre-and posttests. Data collected were analyzed using ANCOVA, and the results obtained showed a statistically significant mean difference between the groups [F(1, 218) = 84.12; p < 0.05], indicating that CTCA improved students' performance in nuclear chemistry. We also found no statistically significant difference in the achievement of male and female students in the experimental group. Within the limitations of the study, we concluded that CTCA is a viable culturally relevant tool for teaching chemistry concepts. The future directions of the study were also highlighted.
Chemical safety, a practice of protecting humans and the environment in which they work and live from the deleterious effects of chemical substances, was investigated in this study in Nigerian secondary schools. Using a mixed-method survey, we investigated the awareness level and implementation of the best practices of chemical safety by 1246 senior secondary school chemistry students. Students in rural schools were found to have a lower level of awareness of chemical safety compared to the students in urban schools. Statistically significant differences were found in all except one of the awareness measureswashing hands before practicals and after leaving the chemistry lab. Urban students were more in breach of chemical safety practices than students in rural schools. Most of the observed differences were statistically significant (p < 0.001). Interview (qualitative) data from 20 students show four emerging themes to explain the findings, including a low level of chemistry laboratory resourcing, poor chemical safety training of the teachers, inadequacies in safety tools, charts, and kits, and weak enforcement of safety regulations. Based on the data from the study, recommendations were made for bolstering the awareness level of students in chemical safety and their chemical safety practices. These include the incorporation of chemical safety in the core curriculum, requiring quality assurance entities to enforce resourcing of basic safety equipment to schools, government-directed workshops on the need for chemical safety, and requiring teachers to provide chemical hazards information to students.
Poor performance of students in chemistry shows that they are having difficulties in learning, mastering the content, and applying what they have learned in examinations. The purpose of this study was to find out the difference in (a) retention of information by students taught nuclear chemistry using the culturo-techno-contextual approach (CTCA) and lecture; (b) retention of information by male and female students taught nuclear chemistry using CTCA, and (c) the interaction effects of gender and method on retention of information by students taught nuclear chemistry using CTCA and lecture. Learning theories of Vygotsky’s constructivism theory, Ausubel’s theory of meaningful learning, and CTCA’s philosophical framework were adopted. This study used explanatory sequential mixed methods; quasi-experimental research design was adopted. A total of 91 senior secondary II students (SS2) (equivalent of grade 11 in the American system) participated. Split-half was used to test the reliability of the nuclear chemistry achievement test (NCAT), and a Spearman–Brown of unequal length coefficient value of 0.80 was obtained. A statistically significant difference was found in the retention of information by students taught nuclear chemistry using CTCA and lecture [F(1,88) = 263.06; p = 0.00] which was in favor of the CTCA group (experimental). A statistically significant difference was not found for gender [F(1,46) = 0.39; p = 0.53]. The statistical interaction effect of method and gender was not significant [F(1,86) = 0.25; p = 0.62]. We recommended that the use of CTCA should be adopted by chemistry teachers in secondary schools to enhance learning.
This study is concerned with the persistent underperformance of secondary school students in Nigeria in physics. The study was conducted in two phases. Phase one was a survey of difficult concepts in physics, while phase two explored the potency of culturo-techno-contextual approach (CTCA) in breaking the barriers to meaningful learning of refractive indices, which ranked the most difficult concept in phase one of the study. A total of 1621 SS3 students from Nigeria and Ghana participated in the survey phase. The second phase employed a mixed-methods approach (quasi-experimental and interviews) with a total of 205 SS1 students. The control group was taught with the lecture method and had 96 students (54 males; 42 females), while the experimental group, taught with CTCA, had 109 students (65 females; 44 males). Both groups had a pretest and posttest using the achievement test in refractive indices; treatment lasted four weeks. Data gathered in the survey were analyzed using mean rank analysis, and refractive indices was perceived as the most difficult to learn. Phase two data were analyzed using one-way ANCOVA since intact classes were used. The result obtained showed that the experimental group performed better (mean for experimental = 15.49; control 11.97; F (1, 202) = 64.48; p < 0.01)) than the control group. Implications of the study are highlighted and the need for further studies is recommended.
