Nutritional Status and Associated Factors of Pregnant Women Utilizing Traditional Birth Attendants (TBAs) in Ogun State, Nigeria
(Lead City University Ibadan, 2025-12) HalimatAbosede OGUNSANYA
In Ogun State, Nigeria, a significant number of pregnant women utilize the services of Traditional Birth Attendants (TBAs) for their prenatal care and delivery. The nutritional status of pregnant women is a critical determinant of both maternal and fetal health outcomes. The study investigates the socio-demographic characteristics and nutritional knowledge of pregnant women utilizing Traditional Birth Attendants (TBAs) in Ogun State. This study employed a cross-sectional approach. A total of 425 pregnant women were interviewed for this study. Findings shows that majority of pregnant women utilizing TBAs in Ogun State do not meet the recommended dietary intake for several essential nutrients, including energy, iron,
Vitamin B12, and zinc. Only 14.8% of pregnant women have good nutritional status. Findings reveals that BMI was significantly associated with nutritional status, with obese (12 1.383,103.376 p value 0.024) and overweight (5.919(1.138,30.772 p value 0.035) women having higher odds of poor nutritional status. A large proportion of pregnant women who utilize TBAs in Ogun State have poor nutritional knowledge (76.7%). Factors significantly associated with good nutritional knowledge included secondary education level, being married, specific occupations, husbands having secondary or tertiary education, holding certain food taboos and cultural beliefs, consuming 3-4 meals daily, and not skipping meals. The findings
highlight the critical need for targeted interventions to improve the nutritional status and knowledge of pregnant women who utilize TBAs in Ogun State.

(Lead City University Ibadan, 2025-12) Rebecca Iyabo OGUNRINDE
Chief Examiner’s reports of WAEC highlight persistent challenges, particularly in Ecology, where students struggle with critical thinking, analytical reasoning, and real-world application of biological concepts. This study determined the Effects of Team and Project-based learning strategies on senior secondary school students' achievement in Ecology in the Abeokuta Metropolis, Nigeria. Four hypotheses were formulated and tested at 0.05 level of significance. The pretest–posttest control group quasi–experimental design was adopted. The study population comprises 3,680 SS II students (1,706 male and 1,974 female students); from which, a total of 91 participants (44 male and 47 female students) from the three randomly selected schools participated in this study. Ecology Achievement Test (EAT) (KR-20 = 0.76) and Instructional Guides for Teaching and Learning Ecology were used as instruments for data collection. Analysis of Covariance (ANCOVA) was used for data analysis. There was a significant main
effect of Team–based learning strategy on senior secondary school students’ achievement in Ecology (F(1; 55) = 160.770, p < 0.05, partial η² =0.745). There was significant main effect of Project-based learning strategy on senior secondary school students’ achievement in Ecology (F(1;57) = 79.050, p < 0.05, partial η² = 0.581). There was no significant main effect of gender on senior secondary school students’ achievement in Ecology (F(1; 88) = 0.002, p > 0.05, partial η² = 0.000). There was significant interaction effect of Team–based learning strategy, Project-based learning strategy and gender on senior secondary school students’ achievement in Ecology (F(5;84) = 40.191, p < 0.05, partial η² = 0.705). Based on the findings, the study concludes that Team based and Project-based Strategies enhanced students’ achievement. The study recommends the adoption of these innovative strategies in teaching Ecology to promote better academic outcomes among senior secondary school students regardless of gender differences.

Eco-benign Synthesis, Characterization, and Application of Metal-oxide Nanoparticles in Solar Cells and Photodegradation of Neomycin
(Lead City University Ibadan, 2025-12) Oluwole Elijah OGUNBIYI
The quest for renewable energy and cost-effective degradation of antibiotics has led to the synthesis of Metal-Oxide (MO) nano-photocatalyts via eco-benign approach. The metal oxides were synthesized biogenically using Syzygium malaccense leaf extract (as capping and stabilizing agents) and Aluminum sulphate octadecahydrate, Copper sulphate heptahydrate and Zinc sulphate heptahydrate salts as precursors. The synthesized aluminum oxide (Al2O3), Copper II oxide (CuO) and Zinc Oxide (ZnO) nanoparticles (NPs) were characterized using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Energy dispersive x-ray (EDX), X-ray diffraction (XRD), and ultraviolet (UV) spectroscopy. The materials were used for the photodegradation of Neomycin (NEO) and as photoanode, counter electrode and insulating spacer respectively in Dye Sensitized Solar Cells (DSSCs). The FTIR showed absorbance with range value between 400-800 cm-1 which corresponds to Al-O Cu-O and Zn-O vibrational stretch of the MOs. The optical properties of Al2O3 CuO and ZnO NPs were determined using Tauc’s plot with band gap energy values of 2.09, 2.05 and 3.23 eV and maximum UV-Vis absorbance values of 371.61, 370 and 371 nm. The SEM micrographs of Al2O3, CuO, and ZnO NPs showed a consistent spherical shape, with average particle sizes of 27.50 nm, 11.01 nm, and 21.98 nm, respectively. The EDX confirmed the elemental composition of the nanoparticles. DSSCs utilizing Al2O3,CuO and ZnO NPs demonstrated a 1.79, 3.44 and 6.4% power conversion efficiency in an increasing order of ZnO > CuO > Al₂O₃ > Control (Without NPs). After 120 min of UV irradiation, 75 and 95% of NEO were degraded with CuO and ZnO nanoparticles respectively. ZnO photocatalyst proved more effective than CuO photocatalyst at degrading the antibiotic. The kinetic studies shows that K values of CuO and ZnO photocatalysts had the values of 0.0072 and 0.0179 min−1 while R2 = 0.83 and 0.82, respectively. The stability of the photocatalyst showed that the produced material (ZnO biosynthesized nanoparticles) had a major impact on both photocatalytic performance and power conversion efficiency. The findings of this study present the biogenically synthesized MONPs as low-cost, and eco-friendly material for energy conversion and photocatalyst for environmental remediation purposes.

Teachers’ Reward Systems and Professional Qualifications as Determinants of Teachers' Productivity in Senior Secondary Schools in Abeokuta Metropolis, Ogun State
(Lead City University Ibadan, 2025-12) Mercy Oreoluwa, ODUYALE
Teachers play a key role in delivering quality education. However, recent evidence suggests a decline in teachers' productivity in Abeokuta, Metropolis, Ogun State, prompting investigations into the factors influencing teachers’ productivity. While previous studies have examined the influence of teacher reward systems and professional qualifications on teachers' productivity separately, limited research has explored their
combined effect. A descriptive survey research design was employed. The population for the study comprised 1,370 teachers and 35 principals of public senior secondary schools in Abeokuta Metropolis, Ogun State. Using a multi-stage sampling procedure, quantitative data were collected from 398 teachers using the TRSPQSSS (α = 0.829) and from 20 principals using the TPSSS. Frequency counts, mean, and inferential statistics of
multiple regression were employed to answer the research questions and test the hypotheses at a 0.05 level of significance. The results revealed that both teachers' productivity (x̄ = 3.28) and the level of professional qualifications (x̄ = 3.28) were high. However, the adequacy of teachers' reward systems was moderate, with an overall weighted mean of 2.64. Multiple regression analysis indicated no significant combined influence of teachers’ reward systems and professional qualifications on teachers’ productivity (R = 0.175, R² = 0.031; F(2,17) = 0.269; p > 0.05). Individually, teachers'
reward systems did not significantly influence teachers’ job productivity (β =-0.055, t= 0.211 p = 0.835.). Professional qualifications also showed no significant influence (β = 0.145, t = 0.555, p = 0.586). In conclusion, while senior secondary school teachers in Abeokuta Metropolis exhibit high productivity levels, reward systems and professional qualifications do not appear to effectively drive their productivity. Based on these findings, it was recommended among others that the government and key education stakeholders review and enhance teachers’ reward systems and professional qualification standards to further increase teachers’ productivity.

Academic Qualifications and School Organisational Climate as Predictors of Junior Secondary School Teachers' Job Performance in Ibadan Metropolis, Oyo State
(Lead City University Ibadan, 2025-12) Goodness Ebunoluwa ODUYALE
Performance of teachers in secondary schools in Nigeria has been a great concern to educational stakeholders. This is due to the pertinent and sensitive role teachers’ play in the attainment of desired educational goals. However, in many Nigerian secondary schools, particularly in Oyo State, concerns have been raised about the declining quality of teaching and the low performance of students in both internal and external examinations. This study therefore investigated Academic Qualifications and School Organisational Climate as Predictors of the Job Performance of Junior Secondary School Teachers in Ibadan Metropolis, Oyo State. The population of the study included 5754 public junior secondary school teachers in the study area. A sample of 574 teachers were selected using proportional and random sampling techniques respectively. AQSOCJSSTJP (α = 0.874) was used for data collection. Descriptive statistics of frequency, percentage, mean and standard deviation, were used to answer the research while the hypotheses were tested with the use of inferential statistics of multiple regression analysis at 0.05 level of significance. The level of teachers' job performance is high at 3.27. A multiple regression revealed that the combined influence of academic qualifications and school organisational climate on junior secondary school teachers’ job performance in Ibadan Metropolis was statistically significant, (R = 0.54, R² = 0.29, F(2, 565) = 114.29, p < .001). Similarly, school organisational climate had a stronger and statistically significant influence on teachers’ job performance (β = 0.54, t = 15.08, p
< .001). However, academic qualifications had no significant relative influence on teachers’ job performance (β =–0.01, t =–0.38, p = .702). It was recommended that the government, school owners and educational stakeholders should enhance the value of academic qualifications through targeted continuous professional development programmes and improve the institutional environment by providing adequately equipped classrooms, laboratories, infrastructural and instructional materials.
