MATHEMATICS AS STORY TELLING (MAST): A FOCUS ON TEACHING AND LEARNING ALGEBRA
Abstract
Mathematics education does not seriously involve indigenous culture of Nigeria, thus students continue to be the most mathematically disadvantaged group especially at the secondary school level. Conventional wisdom with regard to Indigenous Mathematics education is to utilize practical and visual teaching methods, yet the power of Mathematics and the opportunities it brings for advancement lie in symbolic understanding. This paper dwells on a teaching approach Math As Story Telling (MAST) which can assist students understand algebra through creating and manipulating their own symbols for equations. It discusses effective indigenous Mathematics teaching. It describes the MAST approach and analyses its semiotic processes, discusses applications of the approach, and draws implications for indigenous Mathematics learning. The paper recommends that collaboration is required to meet up with language and other problems that the approach will normally encounter when adapted to a new cultural setting which includes political, mathematical content, community based and pedagogical. This collaboration, the author emphasises should be among teachers, researchers and community where the approach is to be adopted.

THE PLACE OF SCHOOL-BASED MANAGEMENT COMMITTEES (SBMC) IN IMPROVING ACCESS TO BASIC EDUCATION IN FAGGE LOCAL GOVERNMENT AREA OF KANO STATE, NIGERIA
Abstract
The increasing number of out of school children in Nigeria is very disturbing. It is observed that many school age children are out of school and are seen on the streets roaming about aimlessly during school hours without access to education. This disturbing trend is a complete negation of one of Nigeria’s philosophies of education which provides that education is a right of every Nigerian irrespective of gender, social status, religion, ethnic background and any peculiar individual challenges. This paper examined the impacts of School Based Management Committees (SBMCs) in improving access to Basic Education in Fagge Local Government Area of Kano State, Nigeria. This review was to address the dearth in available literature for use by researchers, students, ministry of education and other related shareholders who will like to have access to literature to further strengthen and sustain the impacts of SBMC in improving access to Basic Education in Fagge Local Government Area of Kano State, Nigeria. The paper x-rays the strategic contributions of SBMC in improving access to Basic Education in Fagge Local Government Area of Kano State. This is because, children of school age still roam the streets without access to Basic Education in communities where schools do not have functional SBMC. The paper recommended among others that; SBMC should be established and efforts should be made to ensure its effective functions in all basic education institutions in Fagge Local Government of Kano State, the government and community should re-engineer advocacy for awareness and contributions of stakeholders in the provision of education.

BIODIESEL FROM USED COOKING OIL VIA CALCIUM OXIDE LOADED ACTIVATED CARBON CATALYZED TRANSESTRIFICATION REACTION
Abstract
In this study, biodiesel was produced from the used cooking oil using a two-step catalyzed transesterification reaction. A calcined Calcium oxide activated carbon (CaO/AC) impregnation method serve as the composite catalyst. The CaO/AC and corresponding fatty acid methyl ester (FAME) were characterized by FTIR and XRD and for identification of functional groups, crystal structure of catalyst and basicity nature of the catalyst. Esterification and tranesterification processes were optimized using response surface methodology (RSM) based on central composite design (CCD). Under optimal conditions of methanol to oil ratio for 20:1 at reaction temperature of 333K, catalyst loading of 0.3 mg and reaction time of 40 min. The optimal conversion of 92.7% was recorded for the transestrification of used cooking oil and CaO/AC as catalyst. The Physico-chemical analyses carried out on the produced biodiesel gave strong indication that it can serve as an alternative feedstock, having recorded a comparable flash point of 102 °C to American Society of Testing Materials and European Committee for Standardization standards. The acid value of the used cooking oil was (4.09), specific gravity was (0.9711 g/cm3) kinematic viscosity was found to be (9.5mm/s) and the PH was also found to be (8.52). These values indicates that the used cooking oil can be very useful of high yield with zero effect on the environment.
CURBING EXAMINATION MALPRACTICES IN COLLEGES OF EDUCATION THROUGH EFFECTIVE TEACHING AND LEARNING FOR QUALITY ASSURANCE

Abstract
This study sought to determine the effects of flipped learning strategy on NCE Mathematics students’ interest and achievement in trigonometry. The study employed a quasi-experimental 2 x 2 factorial research design. The sample of the study consisted of 60 students, who had a personal computer and Internet access at home. They were randomly assigned into an experimental group of 32 students (22 males, 10 female) and control group of 28 students (20 males, 8 female) The instruments used for data collection during the pre-test and post-test consisted of a trigonometry achievement test (TAT) and trigonometry interest scale (TIS). The TAT was validated by specialists in mathematics education and measurement and evaluation using table of specifications constructed for the multiple choice test items. The multiple choice test had average difficulty and discrimination indices of 0.43 and 0.55 respectively. The reliabilities of the multiple choice test items and trigonometry interest scale were established using the coefficient of internal consistency based on Cronbach Alpha ().The reliability coefficients for the TAT and TIS were 0.68 and 0.75 respectively. The data collected from the pre-test and post-test were subjected to statistical analysis using the Statistical Package for Social Sciences (SPSS). The research questions were answered using descriptive statistics while the hypotheses for the study were tested using t-test statistics and the Analysis of Covariance (ANCOVA) with pre-test scores as covariates at 0.05 level of significance. The findings from the study showed that: flipped learning strategy was more effective than the lecture method in improving students’ academic achievement and interest in trigonometry. The result also shows that there was no significant difference between the achievement of male and female students from the experimental group in trigonometry and that there was no significant interaction effects of treatment and gender on students’ achievement in trigonometry. It was recommended among others that Curriculum planners and educational policy makers should consider a review of the curriculum to incorporate flipped classroom strategy into the Nigeria Certificate in Education Mathematics Curriculum
