TRENDS IN ACTIVE LEARNING PEDAGOGIES IN BIOLOGY EDUCATION: A SYSTEMATIC DOCUMENTARY CONTENT ANALYSIS OF GLOBAL RESEARCH EVIDENCE
(Jurnal Saintifik (Multi Science Journal), 2026-03-26) Opeyemi Abdullahi ALABI; Abdulraheem Dare GBIGBADUA; Olufunke O KAYODE; Olatunji Yusuf ABDULRAHEEM
Biology education plays a crucial role in developing scientific literacy, critical thinking, and the ability to understand complex biological systems. In response, active learning pedagogies have increasingly been adopted in biology education to enhance student engagement, improve conceptual mastery, and support deeper learning. The purpose of this study was to examine global trends in active learning pedagogies in biology education through a systematic documentary content analysis of empirical research. Specifically, the study sought to identify dominant active learning strategies, analyse methodological patterns and geographical distribution of studies, examine reported learning outcomes, and map the theoretical frameworks underpinning this body of research. The study employed a systematic documentary content analysis design. The selected studies were analysed using a structured coding framework that combined quantitative frequency analysis with qualitative thematic synthesis. The findings reveal a substantial growth in active learning research in biology education, with inquiry-based learning, problem-based learning, flipped classroom models, cooperative learning, and technology-enhanced instruction emerging as the dominant pedagogical approaches. The analysed studies consistently report improvements in academic achievement, conceptual understanding, student engagement, and learning retention. The analysis also indicates that constructivist, sociocultural, and experiential learning theories form the principal theoretical foundations of these pedagogical approaches. Overall, the study contributes to biology education scholarship by synthesising global empirical evidence on active learning practices, clarifying their theoretical grounding, and providing evidence-based insights that can inform instructional practice, curriculum development, and educational policy aimed at improving biology teaching and learning.

Effect of Cow Bone Ash on a Stabilized Lateritic Soil for Road Work
(Neewaj Journal of Multidiciplinary Research and Innovations, 2026) Abdulrauf Toyin KURANGA, Sulaiman Olayinka SUBAIR, and Habeeb SOLIHU
This research investigates the potential of cow bone ash (CBA) as a stabilizer for lateritic soil, aiming to improve its geotechnical properties for road construction and mitigate environmental pollution from bone waste disposal. Lateritic soil samples were collected from Peke Airport Road and stabilized with varying percentages of CBA (0%, 2%, 4%, 6%, 8%, and 10%). Standard laboratory tests, including specific gravity, particle size distribution, Atterberg limits, compaction, and California Bearing Ratio (CBR), were conducted according to British Standards (BS 1377: 1990 and BS 1924: 1990). demonstrating improved geotechnical properties such as increased unsoaked and soaked CBR values (from 51.0% to 57.0% with 10% CBA), reduced Atterberg limits (LL decreased from 44.5% to 30.0% with 10% CBA), and enhanced compaction characteristics (MDD increased from 1660 kg/m³ to 1770 kg/m³ with 10% CBA), while also considering the trade-off of increased optimum moisture content (OMC) from 12.0% to 17.5% with increasing CBA content, necessitating further analysis to determine the optimal CBA percentage for optimal stabilization.

Investigation on Fluoride Concentration in Well Water and Its Health Implications: A Case Study of Gwagwalada, Gwagwalada Area Council, FCT, Abuja
(Journal of Advanced Environmental Research and Technology. Published by Tarbiat Modares University Journals System, 2023) SOLIHU HABEEB, Ismaeel Abdulraheem, Solomon Olakunle Bilewu, & Ganiyu Adeniyi Adeogun
This study focuses on determining the concentration of fluoride ions in selected hand-dug wells and investigating its health implications in Gwagwalada Area Council, Federal Capital Territory, Abuja. The necessity for this investigation arose from observed health issues, including dental and skeletal fluorosis among the residents in the area. Fifteen sampling points (well water sources) were chosen in the study area, and a total of forty-five samples (three per sampling point) were collected. The calorimetric water quality analysis method was employed to analyze these samples in the laboratory. Additionally, the Inverse Distance Weighting (IDW) interpolation method was used to generate a spatial variation map for fluoride ion concentration using ArcMap. The results indicate a concentration range of 0.122 mg/L to 1.910 mg/L across the study area. When compared with the recommendations for fluoride ion concentration key words in the Nigeria Industrial Standard (NIS) for drinking water (0.1 – 1.0 mg/L), approximately 67% of the sampling points (10 out of 15) fall within the recommended values, while 33% fall outside. The areas with higher fluoride ion concentrations include Dupa 1, Dupa 2, Tunga Maje 1, Tunga Maje 2, and Old Kutunku 2. The study concludes that the observed dental and skeletal fluorosis in these areas can be attributed to the consumption of water with high fluoride concentrations.
