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.

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 measureswashing 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.

This study investigated the impact of Ethnobiology-Based instruction Peer Tutoring on Achievement of Senior Secondary School Biology Students in Ogun State. The study employed Explanatory sequential mixed-methods approach. The quantitative approach was quasi experimental pretest-posttest non-equivalent group design. Three research questions and one hypothesis was formulated to guide the study. The population of the study comprised of all Biology students in public Senior Secondary Schools in Abeokuta zone. Purposive sampling technique was used to select six Public Schools from two zones (Abeokuta South and Abeokuta North). Biology students in six intact classes of SSS III took part in the study. The sample size of 313 biology students with 101 students in the experimental group 1 (48 male and 53 female), 117 students in the experimental group 2 (57 male and 60 female) and 95 students in control group (38 male and 57 female) which were taught the same biology content for a period of four weeks. The experimental groups received instructions through the use of Ethnobiology-Based Instruction and Peer Tutoring while the control group was taught using lecture method. The data gathering instruments were Biology Achievement Test (BAT) and Students Semi-structured Interview Guide (SSIG). The reliability coefficient of the BAT was established using test- retest and yielded 0.87. Descriptive statistics in form of mean, standard deviation and histogram plot were used to answer the research question while the hypothesis was tested using ANCOVA at 0.05 level of significance. The inferential analysis of hypothesis one has a significant difference on Students’ academic achievement in Biology (F (2,309) = 386.85; p < 0.05), this indicated that the hypothesis is hereby rejected since a significant difference is obtained. The results from the study revealed that the treatments positively improved the academic achievements of students and the students taught using ethnobiology-based instruction had higher test result and outperformed those in Peer Tutoring and lecture method group, but the students in Peer tutoring group also performed better than those in lecture method group. This implies that Ethnobiology-Based instruction is more effective in enhancing Students’ performance in biology and it helps to break barriers to meaningful learning of biology. Based on the findings of this study, it was recommended that Biology teachers should relate learning to students’ cultural views and encourage peer tutoring.
