Item Workload and professional competence as a correlate of mathematics teachers’ teaching effectiveness in secondary schools in Osun State, Nigeria(2019-06) Tella, A.; Akinleye, O. T.This study is hinged on the balancing of the workload and professional competence of mathematics teachers in secondary schools in Osun State, Nigeria which was premised on cognitive load theory. The study adopted the descriptive survey design. One hundred and nineteen mathematics teachers were randomly selected from both public and private secondary schools in 10 local government areas of Osun State. Instruments used were Workload Scale (r=0.78), Professional Competence Scale (r=0.83) and Teaching Effectiveness Scale (r=0.87). Data were analysed using descriptive statistics of frequency count, percentage, mean, while Pearson product moment correlation, t-test and Analysis of variance were used for analyzing the data at 0.05 level of significance. Professional competence (r=0.39) and workload (r=0.26) had positive significant relationship with mathematics teachers' teaching effectiveness. Mathematics teachers' teaching effectiveness in terms of methodology, curriculum and textbook usage, knowledge of their students, context and self were high as against the threshold of 3.0 as the criterion point. Among other things, it was recommended that there should be re- evaluation of the professional training of Mathematics teachers regardless of where they work.Item Perception and use of youtube by music lecturers and librarians in selected tertiary institutions in Kwara State, Nigeria(Taylor & Francis, 2018) Tella, A.; Okemute, F.; Tella, A.This study examined the music lecturers and librarians use and perception of YouTube in selected Kwara State tertiary institutions. Survey approach was adopted to conduct the study. The sample comprised 35 respondents (20 librarians and 15 music lecturers). Three research questions were answered while data were analyzed using percentage, frequency count, and cross tabulation. YouTube was used by the music lecturers mostly for teaching, research and learning, enhancing learning experience, and engaging students with the contents of music lessons. Librarians on the other hand use YouTube mostly as reference point for events and occurrences, teaching tool for library instruction; and for communicating other libraries.Item Mathematics teachers' usage of inclusive instructional activities in some special schools in Ibadan, Oyo State(Department of Special Education, University of Ibadan, 2018-07) Tella, A.Inclusive Education (IE) is a policy and principle aimed at educating students with disabilities and their counterparts who are without disabilities within the same classroom. It brings all students together in one classroom and community, regardless of their strengths or weaknesses in any area, and seeks to maximise the potential of all students. It is one of the most effective ways of promoting an inclusive and tolerant society. It is known that 73 million children of primary school age were out of school in 2010, this was lower than over 110 million out-of-school children in the mid-1990s, according to new estimates by the UNESCO Institute for Statistics (UIS). This study, therefore, was carried out to investigate the level and extent of mathematics teacher usage of inclusive instructional activities in their teaching in some special schools in Ibadan, Oyo State, with the objective of catering for students with special educational needs. The respondents were 11 mathematics teachers from four purposively selected junior secondary schools that offer inclusive education for students with and without disabilities. The results reveal that mathematics teachers do not use inclusive instructional activities. The awareness and level of usage (2.16) was low. There is a significant difference in the utilisation of instructional activities of male and female mathematics teachers (t = 4.564; p< 0.05), with female teachers having the higher usage of instructional activities. The study, therefore, recommends among others, that mathematics teachers should be trained to use inclusive instructional activities that incorporate the inclusive education.Item Revitalizing mathematics education preparation in Nigeria for national development: an innovative view(Modestum, 2018) Tella, A.Mathematics education currently is not in a good phase as regard its product in term of marketability, teachers’ quality, subject mastery, professional competent, pedagogical acumen among others. National development in the context of teacher preparation and other so called in Nigeria should be seen within perspective of overall progress because national development embodies the overall gross progress people achieve within the context of its economic, political and socio–cultural potential. It has since become an undisputable fact that education is one of the potent tool for social transformation for national development anywhere in the world and in all sphere of political system. It is therefore imperative to look critically at different ways to revitalize Mathematics education preparation in Nigeria with reference to national development and putting up various innovations and think–thank syndrome into pre-service teacher preparation.Item Comparison of professional self esteem of public and private school mathematics teachers in Ibadan metropolis, Oyo State(Department of Guidance and Counselling, University of Ibadan, 2018-06) Tella, A.Professional self-esteem is the appraisal of one’s cognitive, emotional and behavioural capabilities that makes an individual a true professional in real sense. It is to get to know the real essence of a profession, its perquisite along and competencies of a professional. Professional self-esteem of mathematics teachers varied across the level and location of operations of mathematics teachers especially between public and private primary school in Ibadan metropolis, Nigeria evidenced from reports. This study, therefore, investigated the comparison of public and private junior secondary school mathematics teachers’ professional self-esteem because of the noticeable negative behaviour of mathematics teacher at this level. The study also examined apart from the comparison between professional self-esteem of public and private mathematics teachers in junior secondary schools, the differential in professional self-esteem of urban and rural mathematics teachers. The study was anchored on social learning theory by Bandura, while survey design was adopted. Multistage sampling procedures was used. First, all junior secondary schools and mathematics teachers in Ibadan metropolis were enumerated. Schools were then stratified into public and private and also into urban and rural schools. Simple random technique was used to select 150 mathematics teachers from 50 junior secondary schools (Private - 49 and Public - 101). Mathematics Teachers Professional Self-Esteem Scale (r = 0.81) was used to collect data. The data gathering lasted four weeks by the investigator with the assistance of three research assistants. Data were analysed using frequency count, mean, standard deviation and sampled t-test at 0.05 level of significance. Qualitative data were content analysed after observing five sessions of focus group discussions with the 25.0% of selected teachers. The results revealed a significant mean difference between public (x = 41.35) and private (x = 29.27); urban (x = 25.41) and rural (x = 21.69); male (x = 6137) and female (x" = 49.53) professional self-esteem of mathematics teachers. The professional self-esteem was higher in term of public, urban, and male mathematics teachers. Mathematics teachers’ professional self-esteem should be sustained and strengthened through incentives, good reward system, marking allowances, teacher gender sensitivities, prompt and timely promotion as at when due.Item Mathematics and curriculum development(2017-12) Tella, A.The unprecedented changes that are taking place in today's world will profoundly affect the future of today's students. To meet the demands of the world in which students will live, students will need knowledge of mathematics to adapt to changing conditions and to learn independently. Mathematics is the abstract study of topics such as quantity (numbers), structure, space and change. Major development in mathematics education in this millennium has been the increased amount of mathematics that all citizens are expected to know. Today’s mathematics curriculum must prepare students for their future roles in society by equiping them with essential mathematical knowledge and skills of reasoning problem solving communication and most importantly, with the ability and the incentive to continue learning on their own. This paper focuses on the mathematics and curriculum development which includes what is mathematics, mathematics processes, curriculum and curriculum development, processes of planning and development of curriculum. Problems and prospects of mathematics teaching in Nigeria secondary schools were also discussed, while recommendations were provided.Item An analysis of perceived usefulness of google scholar by the postgraduate students of the University of Ilorin, Nigeria(AOSIS (Pty) Ltd., 2017) Tella, A.; Oyewole, M.; Tella, A.Background: Google Scholar provides user-friendly information resources and is very effective in finding information to satisfy various information needs, especially by the research students. However, despite its usefulness in satisfying information and research needs of the research students and researchers as a whole, the lingering effect associated with it is drawing students away from libraries. Similarly, there have been limited studies conducted to examine the level of perceived usefulness of Google Scholar by the graduate students, particularly in the context of the University of Ilorin, Nigeria. Objectives: The study examined the perceived usefulness of Google Scholar by the postgraduate students of the University of Ilorin, Nigeria. Methods: A total of 223 postgraduate students selected through simple random sampling from 15 faculties that made up the University formed the sample for the study. A survey approach was adopted using a questionnaire to gather data from respondents. Six research questions were developed to guide the study. Results: The results demonstrate that the majority of respondents strongly agreed and agreed that they were aware of Google Scholar and usually used it. However, the respondents were not satisfied with Google Scholar as it does not either speed up their research or make their research easier. Google Scholar was considered useful because it covers broad topics in the area of interest and usually provides relevant articles related to the respondents’ search done through this platform. Conclusion: The study concluded by recommending, among others, that there is a need for orientation programmes to enhance the use of Google Scholar via the university libraryItem Self-regulated learning strategies as predictors of senior secondary school students’ chemistry achievement in Ondo State, Nigeria(Faculty of Education and Extension Services, Usmanu Danfodiyo University, Sokoto, Nigeria, 2017-12) Tella, A.The study investigated on self- regulated learning strategies as predictors of Chemistry students’ attitude to Chemistry in senior secondary schools in Ondo State. The research adopted survey research design. 400 students were used for the research work which was drawn randomly using simple random sampling technique. The research instruments for the study were SRLS questionnaire containing 10 items on each of the component and students’ attitude to Chemistry (SATC) questionnaire with 25 items. The validity of the instruments was assessed and found to be adequate by the experts. Crobanch alpha was used to determine the reliability of SRLS with a coefficient of 0.86, 0.89, 0.85 and 0.96 and 0.78 for (SATC) at 0.05 level of significance. The data collected was analysed using descriptive and inferential statistics such as: mean standard deviation, Pearson Product Moment Correlation and Analysis of Variance. The study revealed that there was significant relationship between goal setting (r = 0.063; P>0.05) and students’ achievement in Chemistry. Self- monitoring (r = 0.025; P<0.05), self- evaluation (r = 0.012; P<0.05) and self-efficacy (r = 0.064; P<0.05) had significant relationship with students' achievement in Chemistry. The result also revealed that there was no composite contribution of SRLS on students’ achievement in Chemistry (F(4,395) = 0.673; P>0.05). None of the independent variables predicts students’ achievement in Chemistry. Based on the findings it was recommended that students should be encouraged to develop enough self-regulated learning strategies that will facilitates their learning while Government should supply new materials like Chemistry textbooks so that students would be exposed to more facts about Chemistry and teachers on their part should improve themselves academically whenever such opportunity are available so that they can get better.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 Teachers quality as correlates of students learning outcomes in physics in Osun State, Nigeria(Department of Educational Management, University of Ibadan, 2016-09) Tella, A.; Aduramo, O. Y.This study investigated teacher qualities as correlates of student achievement and attitude to Physics among secondary school students in Osun State. A random sampling technique was employed for selecting 55 senior secondary (public and private) schools from two local government areas in Osun State. The sample consisted of 1166 Physics students and 55 Physics teachers. Four instruments were used to gather information. T-test analysis was used as the statistical tool for this study and the findings revealed that the learning outcomes of students do not depend on the qualities of teachers considered which include, qualification of teachers, teaching experience, teachers' use of instructional methods, teachers' use of instructional materials and teachers gender. The study recommended therefore that teachers should be rewarded for their performance. Government should work hand-in-hand to fund secondary schools so as to make learning environment conducive. Parents should not force their children to study the Sciences.
