Item Open Access EFFECT OF LABORATORY APPROACH ON JUNIOR SECONDARY SCHOOL STUDENTS' INTEREST IN GEOMETRY AND MENSURATION IN KEFFI EDUCATION ZONE, NASARAWA STATE(Department of education biology, Nasarawa state university, keffi., 2017-08-06) Musa, D.C.This study determined the effect of laboratory approach on junior secondary school students' interest in geometry and mensuration. A sample of 74 JSII students from two randomly selected government owned secondary schools in Keffi Education Zone, Nasarawa state was used for the study. Quasi-experimental of non - equivalent control group design was used. T\yo research questions were answered and two hypotheses were tested. The instrument, Geometry and Mensuration Interest Scale (GMIS) was developed, validated and used for data collection. Data obtained were analyzed using mean, standard deviation and analysis of covariance (ANCOVA). The results revealed that students have high interest in Geometry and Mensuration when taught with laboratory approach and there is no significant difference in the mean interest scores of males and females. The study recommended that teachers should be encouraged to use laboratory approach in teaching so as to improve students' interest in Mathematics and to eradicate the issue of gender differences in having interest in Mathematics. Authors and publishers of secondary school mathematics textbooks should write and publish the books from the point of laboratory approach and other practical approaches. This will make the contents of such books to be in the context of real life situation thereby upholding students' interest in Mathematics.Item Open Access IMPACT OF EBOLA CRISI ON SCHOOLS’ 2014/2015 ACADEMIC CALENDAR IN ABUJA MUNICIPAL AREA COUNCIL OF FEDERAL CAPITAL TERRITORY NIGERIA(Department of education biology, Nasarawa state university, keffi., 2017-07-03) Jibrin, Abdullahi Tanko; Imi, J.R; Ahmad, I.S,; Musa, U.H; Jerry, K.The study investigated the impact of Ebola crisis on schools’ 2014/215 academic calendar in Abuja Municipal Area Council of Federal Capital Territory, Nigeria. Descriptive survey research design was employed. The population of the study comprised all teachers and students of public and private secondary schools in the Area Council. Simple random sampling technique of hat and draw was applied in selecting the sample for the study. Four public and four private secondary schools were randomly selected out of the numerous secondary schools in the Area under study. Consequently, one principal and four teachers from each school with 25 students formed the sample of the study; thus, a total of240 respondents out of the population of 6,182 are used for the study. Questionnaire was the instrument used in the study. 240 copies of the questionnaires were distributed to the respondents and 240 filled were collected. Simple percentage statistical technique was used to answer the research questions and Chi square was used to test the postulated null hypotheses. Among the major findings were that: Ebola crisis had impact on Abuja Municipal Area Council of Federal Capital Territory schools during the 2014/2015 academic calendar. Also, results indicated that, there were interventions by Nigerian Government during the Ebola crisis. Based on these findings, it was recommended that Government should checkmate the movement of people coming from affected countries. Nigerian government should also provide adequate funds and standard medical facilities during crisis or when natural disaster occurs. Public and private schools should be encouraged to make efforts in restoring academic curriculum whenever there is a natural disaster in the academic calendar leading to termination of academic activities and a subject called natural disaster should be introduced into secondary schools' curricula and to be taught by educational psychologists.Item Open Access INFLUENCE OF TEMPERATURE AND RAINFALL VARIABILITY ON MELON (EGUSI) PRODUCTION IN NASARAWA STATE, NIGERIA(Department of Biology, Nasarawa State University Keffi., 2019-03-04) Tebrimam, Gagbanyi Caleb.Melon is an environmental tolerant crop which is produced massively in Nasarawa state. The itudy is aim at examining the influence of temperature and rainfall variability on melon production (output). Temperature and rainfall are two factors, among others, that influence the production of melon in Nasarawa State. This study covers a period of 19 years (1997-2015). Oata were obtained from secondary sources; melon production data was obtained from Nasarawa State Agricultural Development Programme whereas temperature and rainfall data vere obtained from NIMET. The Walter’s method, as modified by Olaniran, was used to calculate the onset and cessation dates of rainfall and temperature. Multiple regression was used o test the hypothesis using standardized time series of melon production, temperature and 'ainfall. Descriptive statistics was used to represent results in charts, graphs at 95%level of significance. The state has a mean temperature that ranges from 26-28°C and annual rainfall between 1100 - 1700mm with onset in April and cessation in October. Temperature is on the ncrease whereas rainfall is on the decrease, although it is statistically not significant at 95% 'evel. Onset and cessation dates do not influence melon production, as result show that these iates are not significant in melon production. Temperature has little influence on melon production when compared to rainfall. They both constitute 24% influence on melon production. Melon requires between 200 - 230mm of rainfall and 26-28°C of temperature. A weak relationship was observed using multiple regression analysis, having an r-square value of0.239. rt is recommended that agro-meteorologists/climatologists should extend their weather forecast lo melon farmers, intensification of irrigation farming to burst melon production and also ^search should focus on developing of melon resilient seed that can withstand climate variability and change. xiItem Open Access PROBLEMS MILITATING AGAINST EFFECTIVE USE OF E-LEARNING DEVICES IN TEACHING BIOLOGY IN SECONDARY SCHOOLS IN FEDERAL CAPITAL TERRITORY, ABUJA, NIGERIA(Department of Education Biology, Nasarawa State University Keffi, 2019-07-19) Chukelu, C.U.The study investigated the problems militating against effective use of e-learning devices in teaching biology in FCT Abuja. Descriptive survey research design was adopted. There are 215 biology teachers in 62 secondary schools in FCT. 20 schools were selected using simple random sampling technique and 120 teachers were selected from the six area councils of Abuja to produce the sample size of the study. Two instruments were used, Availability of Biology E-learning Devices (ABED) check list and Biology Teacher Use of Eleaming Devices Questionnaire (BTUEDQ) was used for data collection. ABED an r BTUEDQ was validated by two experts in Science Education. Cronbach alpa was used to obtain a reliability coefficient of 0.76 of BTUEDQ while mean and standard deviation were ised to answer the research questions. The study revealed that schools are not adequately equipped with e-leaming devices. Also, that the utilization of e-learning devices in delivering biology lessons is very poor. It is therefore recommended that government should provide adequate eleaming devices, power and internet facilities to schools as well as organize seminars, conferences on computer related programmes for teachers.
