Two research questions and one null hypothesis were formulated and guided the study. The population of the study was 260 principals and 5,826 teachers in Anambra State. Simple random sampling technique was used to select 90 principals and 690 teachers from six education zones in Anambra State, totaling 780 respondents. The instrument for data collection was 20-item questionnaire. The instrument was validated by three experts, two experts from educational management and one expert from Measurement and Evaluation, all from Faculty of Education in Nnamdi Azikiwe University, Awka. The validated instrument was trial tested to evaluate the grand reliability with the internal coefficient of 0.84. Mean and standard deviation was used to answer the research questions while t-test was used to test the null hypothesis at 0.05 level of significance. The major findings revealed that instructional supervision strategies are panacea in repositioning classroom management in secondary schools. More so, those mentioned strategies must be effectively implemented in order to curb the challenges militating against the advancement of instructional supervision. Based on the findings of the study, it was recommended among others that the school administrators should from time to time organize seminars, symposium and orientation in order to enhance the efficacy of instructional supervision among teachers and non academic staff.</em></p> 2024-12-17T00:00:00+00:00 Copyright (c) 2024 International Journal of Contemporary Research and Review https://ijcrr.info/index.php/ijcrr/article/view/928 STUDY OF THE EFFECT OF PROCESS PARAMETERS ON THE YIELD OF FERMENTABLE SUGAR FROM TUBER PEELS VIA ACID AND ENZYME HYDROLYSIS 2021-11-18T12:44:25+00:00 Ikechukwu Maxwell Onoh maxwell.onoh@esut.edu.ng <p><em>The aim of this work is to study the acid and enzymatic hydrolysis of &nbsp;water yam peels using HCl, H<sub>2</sub>S0<sub>4</sub> acids and cellulase enzyme. The cellulase was secreted from Aspergillus Niger (A.niger) fungi. The proximate analysis of the substrate showed that water yam peel is a lignocellulosic biomass with a cellulose composition of 48%. The effect of the process parameters (time, temperature, acid concentration and pH) on the yield of glucose in acid and enzymatic hydrolysis of the water yam peel was respectively investigated. Maximum glucose yield of 44.5% was obtained after 3 days of enzymatic hydrolysis at 30°C and pH 5. The HCl acid hydrolysis showed a maximum glucose yield of 27.3% at 70°C, 5% HCl after 180 minutes. The glucose yield in H<sub>2</sub>S0<sub>4</sub> hydrolysis was relatively lower than that of the HCl with a maximum yield of 26.5% at 70°C, 5% H<sub>2</sub>SO<sub>4</sub> after 180 minutes. In addition to, the functional groups present in the glucose synthesized from ground water yam peels and the standard glucose were evaluated using Fourier Transformed Infrared (FTIR). The FTIR results showed similarities in the functional groups present in both sugars. Yam peel can be used for the production of glucose and further fermentative process to produce ethanol.</em></p> 2024-12-17T00:00:00+00:00 Copyright (c) 2024 International Journal of Contemporary Research and Review
