Item Comparison of Four Covariate Adjustment Methods in Analysis of Mathematics Achievement in Randomised Controlled Trials among Senior Secondary School Students(Positive Psychology Association of Nigeria, 2022) Fehintola, J. O"The study investigated the Mathematics achievement of senior secondary school students in Mathematics in Saki using Project Based Learning Method (PBLM) in enhancing the Mathematics achievement in senior Mathematics among senior secondary school students in Saki. To ascertain the degree of treatment efficacy, a randomised sample of 45 senior secondary school students with 30 and 15 participants each from two different senior secondary schools in Saki West Local Government areas in Saki were selected for the purpose. The randomised control trial design was employed, and a randomized randomised sample that undertook training in PBLM and a control group were used. The instrument used for data collection is Mathematics achievement tests sampled from the National Examination Council (NECO) for 2017 & 2018 objective Mathematics papers. Since the instrument was standardised test prepared by Public Examination body there is no need for revalidation. A pair of pre-test and post-test data was obtained from each participant who formed the basis of the findings using ANCOVA for data analyses. This study present the empirical application of four statistical methods (pre and post-treatment scores with analysis of covariance, post-test scores, difference in pre and post-treatment scores and percent difference in pre and post-treatment scores), using data from a randomised controlled trial of post-test among the senior secondary school students on Mathematics achievement using Project Based Learning Method (PBLM), with and without PBLM treatment, a Randomized Controlled Study trials. Analysis of covariance (ANCOVA) was used to determine the effectiveness of treatment, to adjust for baseline measures and to provide an unbiased estimate of the mean group difference of the post-treatment scores in Mathematics achievement among the participants used. Robustness tests were done by comparing ANCOVA with three comparative methods: the post-treatment scores, change in scores, and percentage change from baseline. All the four methods showed similar direction of effect; however, ANCOVA (93.503; 95% confidence interval [CI]: 89.332, 97.668; p = 0.019) and the post-treatment score (94.100; 95% CI: 89.733, 98.467; p = 0.001) method provided the highest precision of estimate compared with the change score (38.300; 95% CI: 34.215, 42.385; p = 0.001) and percent change (68.462; 95% CI: 60.358, 76.565; p = 0.001). The empirical studies provide the best statistical estimation for analyzing the best statistical estimation for analyzing continuous outcomes requiring covariate adjustment. Our empirical findings support the use of ANCOVA as an optimal method in both design and analysis of trials with a continuous primary outcome.Item Multiculturalism: a panacea to the achievement gap in mathematics in public schools in Nigeria(Institute of Education, Obafemi Awolowo Univeristy, Ile-Ife, 2017) Tella, A.Multiculturalism seeks to recognize, understand, and appreciate cultures other than one' own. Educational Researchers over the years have taken advantage of multiculturalism to bridge the achievement gap and inequality that are related to gender, exceptionality, race, class and ethnicity. Students' performance in Mathematics over the years shows that the teaching and learning of the subject has been consistently reported as poor in most of the secondary and primary schools in Nigeria. This poor performance is more profound in public school where the majority of students are enrolled in Nigeria. A critical look showed that the dearth of effective teaching and learning of Mathematics in public schools in Nigeria has been attributed to lack of resources. It is against these backdrops that this paper highlights the potentials of multiculturalism as a yardstick to bridge the achievement gaps in Mathematics teaching in public schools in Nigeria.Item In our match towards scientific and technological advancement, we need nothing short of good performance in mathematics at all levels of schooling. In an effort to achieve this, this study investigated the impact of motivation on students’ school academic achievement in mathematics in secondary schools using motivation for academic preference scale (α = 0.82) as a measuring instrument and achievement test in mathematics (ATM) Two hypotheses were tested for significant at 0.05 margin of error using t-test and analysis of variance (ANOVA) Results showed that gender difference were significant when impact of motivation on academic achievement was compared in male and female students. Also other result indicates significant difference when extent of motivation was taken as variable of interest on academic achievement in mathematics based on the degree of their motivation. Implications, suggestions and recommendations on students, parents, government, counsellors, educational stakeholders, etc were discussed.(MOMENT Kazim Karabekir Cad., Ankara-Turkey, 2007-04) Akinsola, M. K.; Tella, A.; Tella, A.Procrastination is now a common phenomenon among students particularly those at the higher level. And this is doing more harm to their academic achievement than good. Therefore, this study examined the correlates between academic procrastination and mathematics achievement among the university mathematics undergraduate students. The study used a total sample of 150 part 3 and 4 students in the department of mathematics and mathematics education students in the university of Ibadan and university of Lagos, Nigeria. The 35 items academic procrastination scale developed and validated by Tuckman (1991) was used for the collection of data, in conjunction with the subjects GPA scores till date in mathematics. Findings indicates that: a significant correlation was found in the academic procrastination and academic achievement of the subjects in mathematics, significant difference also exists in the levels of procrastination and mathematics achievement of the subjects, with low procrastinators performing better than the moderate and the high procrastinators. Results further reveals the subjects procrastinate the same way irrespective of their gender. Implications of procrastination on academic achievement of students at all levels generally and some effective ways of remediation of procrastination were suggested.
