DEVELOPMENT OF AN ARTIFICIAL INTELLIGENCE BASED SYSTEM FOR NUTRIENT DELIVERY TO GREENHOUSE GROWN CROPS
Get PDFApplying nutrients to crops either on the field or in a greenhouse has been a manual process, especially in developing countries where farmers or greenhouse attendants introduce nutrients based on intuition, or at specific intervals, not knowing exactly when a crop requires the said nutrients. This is one of many reasons why artificial intelligence has been introduced into the agricultural sector. This project was designed to develop an artificial intelligence-based system for the automatic delivery of nutrients to greenhouse-grown crops. The system was built with an Arduino microcontroller serving as the brain box of the system, a soil Nitrogen, Phosphorus and Potassium (NPK) sensor for reading nutrients level, an organic light-emitting diode which display. +he specific nutrient level in mg/kg, while a solenoid valve was incorporated into the delivery mechanism. T. e da*r was logged onto a secure digital (SD) card via SD module installed on the Arduino board. The microcontroller was configured to interpret the varied states of the soil as relayed by the soil sensor; and this involved data capture from NPK sensor, data processing to determine when to release nutrients, and delivery of nutrients if the solenoid valve is activated. The system was evaluated on soil whose nutrients were leached out, placed in a greenhouse, and the performance was satisfactor
Boundaries of empirical approaches in educational research
No full textThis paper critically reviews the research done in education faculties in Nigerian universities. This research, though categorized in postgraduate schools or colleges as mainly in the liberal arts/humanities and the social sciences, depends on the theories and methodologies from other disciplines. The arts and social sciences are disciplines where undergraduates in education take courses in teaching to earn bachelor’s degrees, the postgraduate level offers varied opportunities for educational research to maximize the uniqueness of mixed method research for education
Decolonising the Nigerian Curriculum: a Path to Self-Reliant Education
Get PDFThe process of education is pivotal to the development of any society as no nation can rise beyond the level of her educational development. Curriculum is an important aspect of education; it determines the quality of educational System of any society. The Nigerian education System has suffered great setbacks due to the dysfunctional curriculum which it operates over the years. It has been established that effects of colonisation can still be felt in the Nigerian education sector which had continued to depend on the curriculum handed over from the colonial masters, which had rendered graduates of various institutions unqualified or 'half-baked' and unfit to meet the demands of their society. There has been economies underdevelopment as well as increased dependence on foreign technology. Previous researches have suggested modification of the curriculum as an antidote; however, this has not really yielded expected results due to poor commitment, perpetual change in policies and politicisation of educational decisions. This study adopted the method of philosophical discourse to examine the need to embark on decolonisation of the curriculum as a necessary means to resolve the situation and promote educational sustainability. The paper recommended that learning contents should be made to fit into the practical experiences of the Nigerian society; vocational skills should be inculcated into school activities/learning experiences, traditional values need to be promoted, while indigenous language should be employed alongside English language as modes of communication in schools to promote better understanding among learners
Effect of multimodal assessment packages on senior secondary school students' english listening proficiency in Ibadan metropolis Oyo State, Nigeria
Get PDFThe study determined the effect of curriculum-based multimodal technique on the listening skills proficiency among secondary school students in Ibadan metropolis. The quasi experimental design was adoptedfor this study. The instruments were Oral-based tests with reliability co-efficient of 0.89, Paper- based tests with reliability co-efficient of 0.70. A total of200 students were randomly selectedfrom public and private schools in Ibadan metropolis and were examined. Half of the students (100) are from public-based secondary schools while the remaining 50% (100) are from private schools. Analysis of variance was used in analysing the main and interaction effects of the data collected. The results revealed that there was no significant different in the overall listening skill proficiency of the students based on either of the school or test type. However, there exists a strong interaction between these independent variables. Students from public schools performed better in Oral-based test (ORT), while private school students tends to have better performance in paper- based tests (PBT). The public school students with a mean performance score of79.38%performed better than the private school students (x— 78.5%) in term of the overall average in the conducted tests Based on thefindings, the new (ORT) technique ofassessing listening skill should be adopted by teachers and all public examining bodies in Nigeria in assessing students listening proficienc

Psychoactive substance consumption and criminality among commercial drivers in selected motor parks in Ibadan metropolis, Oyo State
Get PDFSubstance consumption is a major issue that has taken a deep root in our society. This study examined the effect of substance consumption among commercial drivers in selected parks in Ibadan metropolis. The study employed a descriptive survey design and a multistage sampling technique was also used to select two modem parks at Ojoo and Challenge in Ibadan while simple random sampling was used to select 188 commercial drivers at the two parks. A structured questionnaire was used to gather information from the respondents. The data collected were analysed using simple percentage and frequency counts while Pearson Product Moment Correlation (PPMC) statistical package was used to analyse the hypotheses. Findings revealed that the correlation between substance use and reasons for substance use was not significant but positive and low [0.068 (0.352)] which indicate that substances were taken on account of getting high and to remain awake while driving. Also, the correlation between substance use and implications for substance use was significant but negative and low [-0.228 (0.002)]. Findings also showed that the correlation between substance use and measures for eradicating substance use was not significant as well as negative and low [-0.101 (0.169] which means measures were not enforced by the government agency, hence, rules were not adhered to. The study recommends that government agency should develop a device for testing drivers who test positive to any substances, also, the state and local governments should enact laws and sanction any commercial drivers caught abusing substance
Teaching, learning and assessment during covid-19: challenges and prospects of the University of Ibadan ert
Get PDFThe Covid-19 pandemic has brought extraordinary challenges and has affected the educational sectors in all ramifications. This, therefore calls for the need to sustain and provide quality education despite its challenges and forced many institutions to reposition their educational practices which predominantly adopted the conventional methods of teaching and learning, as well as assessment which was on venue-based and restricted in terms of online accessibility, swiftness, assessment and materials interaction. In the new normal period, there is much emphasize to reposition our institutions for teaching and learning in terms of the mode of instruction and assessment. Many countries, Nigeria inclusive were forced to migrate to a more robust innovative online teaching and learning, and different forms of online instruction and assessment using diverse platforms such as Emergence Remote Teaching (ERT), google meet, zoom, Microsoft team and others. These online teaching platforms have implications for lecturer-student interaction, satisfaction, engagement, and success in curriculum planning and implementation issues. Seventy-five lecturers in the faculty of Education from the 11 departments partake in the study. Questionnaires and structured interviews were used to collect data. Data collected were analyzed using the descriptive statistics of mean, while the qualitative data was content analyzed. This study identified the challenges of teaching staff and students in teaching and learning using ERT, University of Ibadan as a case study. Challenges idented includes: internet connectivity, technological experiences, power supply,and lack of access to reliable internet connection .The perceived benefitswere a reduction in transportation costs, effective distance learning, stability in communication and lecturers' familiarisation with online emerging technology. ERT platforms should be designed with engaging and interactive content, instructors and students' learning activities to maintain students’ interest during the lesson session were recommended
The role of social work in mental health and academic performance of students.
No full textSocial workers have an important role in the field of mental health, and social work programs have a responsibility to prepare students for practice in the field. However, it seems that various societies, groups and individuals have questioned the role of social workers in mental health. An increasing number of students entering university are identifying themselves as having mental health issues and those with higher levels of cumulative trauma tend to have more difficulty adjusting personally and emotionally to the transition, and abuse is linked to an increased probability of dropping out of collegeas well as to increased rates of depression and suicide. This paper examines the role of social workers in mental health and academic performance of students. Social workers have a key role in helping community participation and engagement, alongside other primary healthcare workers in delivering mental health support. It is recommended that activities such as case scenarios and role plays be used to prepare the student first, and that students be given the opportunity to practice these skills in actual practice settings as well. School authorities should not wait or watch till a student academic performance degrade totally before he or she is handed to a social worker with mental health experience. Periodic sessions should be organized by school authorities to gauge student mental stability from time to time to avoid any epidemic of mental breakdown which in tum affects their academic performance

Appraisal of impact of NYSC’s skills acquisition and entrepreneurial development programme (SAED) on entrepreneurial development of ex-corps members
No full textThe study assessed NYSC's Skills Acquisition and Entrepreneurship Development programme (SAED) on the entrepreneurial development of ex-corp members that served between 2015 and 2020. In this study, three research questions were posed and addressed. This study adopted a survey research design. 250 masters' students that have undergone NYSC were randomly selected at the University of Ibadan. Three validated instruments were used to collect data for the study: NYSC's Skills Acquisition and Entrepreneurship Development Programme Scale (ANYSCSAEDPS) (r = 0.76), Benefits and Challenges of NYSC's Skills Acquisition and Entrepreneurship Development Questionnaire (BNYSCSAEQ) (r = 0.84). Data were analyzed using descriptive statistics of frequency counts, percentages, mean and standard deviation. The findings revealed that majority of the ex-corp members during NYSC's (SAED) Programme were exposed to educational skills, tourism and cosmetology, while few were exposed to horticulture and landscaping 15 (5.6 percent), power and energy 14 (9.6%), and automobile 8 (3.2 percent). The study also revealed that SAED was beneficial and very good for youth empowerment. It can therefore, be concluded that the SAED programme is beneficial to graduates' empowerment and the reduction of unemployment among youths, although its contribution to the development of entrepreneurial skills was not adequate enough due to some challenges facing its implementation. Consequently, the government should devote more attention to the programme by making resources available for its smooth implementation. Corps members should be re-oriented on the benefits of participating in SAED through their commitments when enlisting for entrepreneurship training during service, among other things
