- ItemEnvironmental health determination and assessment of physico-chemical characteristics in Oloshi River, Nigeria(FTST, 2017) Opara, Jacinta A.; Okwodu, Nicholas E.The Physico-chemical characteristics of the surface waters and sediment in Oloshi River, non-tidal fresh water were studied between July and December 2015. The Oloshi River drains and receives effluents from cassava mill treatment (starch mill) factory and oil companies in the area. The inhabitants are predominantly farmers and fishermen. All parameters were analyzed using standard methods for examination of water and waste water (ALPHA 1998). The results of water and sediment physico-chemical parameter lies between a mean range of 4.2- 4.4 for pH, 28.5°C for temperature, 1.4-4.8 NTU for conductivity, 1.4 – 4.9 NTU for turbidity, 3.9 – 4.4 ppm for Po4, 0.2 – 1.2 for No3, BOD= 1.1 ppm. The results showed low physico-chemical levels which do not pose serious health risk except for phosphate levels with a range of 3.89 to 4.4 ppm. With regard to seasonal variation, dry season recorded higher values than rainy season except for pH and No3 of the sediment parameter in which the rainy season recorded higher than dry season. Increased level of pollutants in the Oloshi River may have significant effect on the ecological balance of the River.
- ItemInquiry-Based Learning and Environmental Education in Nigeria: An Analysis of Students’ Acquisition of Manipulative Skills in Geometric Construction(SCHOLARS WORLD, 2017) Opara, Jacinta A.; Nguuma, JiminThis paper perceives geometric construction as an important aspect of environment education. It examined the effect of IBL on students’ acquisition of manipulative skills in geometric construction in education zone B of Benue State, Nigeria. The study also investigated whether the skills acquisition could be affected by gender and ability levels. Sample for the study comprised of 300 Senior Secondary 1 students selected from six schools within Education Zone B of Benue State using a multi-stage sampling technique. The study adopted a quasi-experimental non equivalent pretest-posttest design. Intact classes were assigned to the experimental and control groups. Data was generated using Geometric Construction Manipulative Skills Test (GCMST) which was the research made essay test. The reliability of the instrument was computed using Pearson’s Product Moment Correlation Coefficient and found to be 0.98. The study was guided by three research questions and three hypotheses. Data collected were analysed using descriptive statistics of mean and standard deviation to answer the three research questions and inferential statistics of Analysis of Covariance was used to test the three hypotheses. Hypotheses tested reveals that students exposed to IBL exhibited greater manipulative skills in geometric construction (F=392.69; p=0.002) than those exposed to conventional methods. In addition, male and female students taught using IBL did not differ significantly in acquisition of manipulative skills (F=1.58; p=0.211). Also, High and low ability students did not differ significantly in demonstration of geometric construction skills acquired (F=0.14; p=709). Based on these findings, the study recommended among others that mathematics teachers should use IBL in teaching students practical mathematics skills. It concluded that IBL is a framework for outcome-based education which is a trust towards greater learner-centred pedagogy therefore it should be considered a useful addition to the variety of existing mathematics teaching approaches that attempts to involve learners more in their own learning.
- ItemManagement of Biodegradable Waste among Rural Residents in Southern Nigeria: Implications for Environmental Public Health(Mediterranean Journal of Social Sciences, 2018) Opara, Jacinta A.This work investigated the management of biodegradable waste among residents in a South-East Locality of Nigeria. The design adopted was descriptive survey design. The population size was 270,902 residents in Ahiazu Mbaise Local Government Area. The sample for the study consisted of 840 respondents selected using a multi-stage procedure. Four objectives guided the study. The data collected were analyzed using descriptive statistics of frequency tables and simple percentages. The study revealed that majority(706; 84&%) of the residents agreed on the common types of biodegradable waste generated; majority use broom and bare hand (hand picking) to collect biodegradable waste with the frequencies of 648 (77%) and 560 (67%)respectively; majority agreed on the methods of transporting biodegradable waste with an overall frequency of 584 (70%) and that majority agreed the methods of disposal of biodegradable waste with an overall frequency of 632 (75%). Based on these, it was recommended among others that health educators should be employed in the ministry of environment with mandate of organizing health talks for the residents to enlighten them on the management of biodegradable and that government should provide adequate means and facilities for the management of waste in our surroundings.
