    Perception of Farmers on Climate Change on Agricultural Productivity in Ninewa Governorate of Iraq
    (Lead City University Ibadan, 2023) Olaleye Olusoji OJO
    The study examined the perception of farmers on climate change on agricultural productivity in Ninewa Governorate of Iraq and was based on the conservation model and high payoff input model/theory. The study employed a mixed research design employing cross-sectional, descriptive, and correlational research design, which were guided by both qualitative and quantitative data collection approaches. Five-point Likert scale questionnaire and key-informant interview were used for data collection. Simple random sampling and purposive sampling techniques were used to select the respondents for this study. Collected data were analyzed using Statistical Package for Social Sciences (SPSS) version 22.0. The study involved a response rate of 81(76%), which was good and acceptable for subsequent analysis. The study succinctly revealed a negative and statistically significant impact on 2 agricultural productivity. Based on coefficient of determination (r =0.172), the findings imply that the explained variation in agricultural productivity due to water scarcity and drought is about 17.2%. Based 2 on coefficient of determination (r =0.171), the findings imply that the explained variation in agricultural productivity due to declining precipitation is about 17.1%. Based on coefficient of 2 determination (r =0.115), the findings imply that the explained variation in agricultural productivity 2 due to extremely high temperature is about 11.5%. Based on coefficient of determination (r =0.2601) the findings imply that the explained variation in agricultural productivity due to dust and sandstorms is 2 about 26.01%. Based on coefficient of determination (r =0.282) the findings imply that the explained variation in agricultural productivity due to climate change is about 28.2%. Consequently, it is concluded that climate change has a negative and statistically significant impact on agricultural productivity. Based on this, it is recommended that the government should invest massively in environmental protection so as to improve on water precipitation in order to boost agricultural productivity in the governorate.

    Prior Knowledge of Relevant Mathematical Concept as Precursor of Academic Achievement in Chemistry in Oyo Metropolis
    (Lead City University Ibadan, 2023) Olaleye Olusoji OJO
    The study examined if student achievement in chemistry could be enhanced by teaching them selected mathematics concepts prior to chemistry teaching or teaching them selected mathematics concepts simultaneously with chemistry. The sample of the study was three hundred students selected by simple random techniques from 4,853 senior secondary II students in Oyo Educational Zone. The design was quasi-experimental involving three groups. Group Awas taught relevant mathematics concepts before chemistry group B was taught mathematics with chemistry simultaneously while group C received no mathematics lesson. The instrument used to harvest data was chemistry Achievement Test (CAT) adapted from West African examinations Council (WAEC) and National Examination Council (NECO) 2011-2020. The groups were pre-tested with the instrument comprising eighty (80) multiple choices question and post-tested with a reshuffled faction of the pre-test after the experiment. The data obtained was analyzed using t-test. The results of the study revealed that group taught relevant mathematics concept before chemistry lessons performed better than the two other groups. It was recommended that curriculum should be designed in a way that relevant mathematics topics essential for chemistry should be taught earlier in senior secondary.
