Effects of The Use Guided Discovery Method On Solving Linear Equation in One Variable Word Problem Among Junior High Shool Form 2 Students (Published)
The study sought to assess the effect of guided discovery approach of teaching Junior High School Form 2 students’ ability of translating and solving of linear equation in one variable word problems. Data were collected by administering pre-test and post-test of five linear equation in one variable word problems to 23 students. The purpose of the pre-test and post-test assessment was to measure change in students’ knowledge and skills of translating and solving linear equation in one variable word problems. The results revealed that majority of the students failed to identify the unknown part of the problem, represent it with defined variable and write correct expression and then transform the expression into linear equations, find the value for the variable and substitute the value of the variable into the equation to verify their answers. With the implementation of the guided discovery approach, the students made sufficient gains in post-test scores when they solved five linear equation in one variable word problems. Paired sample t-tests analysis also revealed a significantly increased the pre-service teachers’ abilities of translating linear equation one variable word problems into algebraic forms and solving them. Consequently, it was recommended that mathematics teachers should make frantic effort and teach students the skills of identifying unknown part of linear equation word problems and representing with defined variable, and then form linear equations. Since one of the most important stages of problem-solving heuristic reasoning processes is to look back, students should be encouraged to make it a point to verify their answers and choose the right answer(s) only.
The Difficulties Encountered by Undergraduate EFL Students with Their Listening Comprehension Skills in PAAET, Kuwait (Published)
The study identifies the difficulties encountered by EFL students with their listening comprehension skills in the English department at the College of Basic Education, Public Authority of Applied Education and Training (PAAET). The study was conducted using the descriptive approach which contained a sample of 357 EFL students. The results found that students encountered moderate difficulties during the three stages of listening: perception, parsing, and utilization. The strongest difficulty was during the first stage, perception, followed by parsing and utilization. These findings can shape classroom policies by constructing an EFL curriculum that emphasizes the role of listening comprehension and integrates listening skills in classroom activities.
Functional properties and sensory evaluations of ‘chin-chin’, bread and biscuits produced from composite flours from African yam bean, Orange fleshed sweet potatoes, plantain, cocoyam, maize, and wheat. (Published)
The aim of this study was to produce ‘’chin-chin’’, bread and biscuit from composite flours of African yam bean (AYB), plantain, maize, orange fleshed sweet potatoes (OFSP), wheat and cocoyam. AYB seeds were fermented in citric acid medium (0.5%). Maize seeds were fermented in tap water for 48hrs. Green matured plantain fruit, cocoyam corm and OFSP tubers were processed into flour. The functional properties of the flours were determined using standard laboratory methods. Products were developed from the composite flours using conventional methods. Sensory evaluations of the products were performed using a 9-point hedonic scale. Descriptive statistics was used to analyze data. Bulk density, water absorption capacity, swelling index, foaming capacity, Potential of Hydrogen, oil absorption capacity, gelation capacity and solubility of the flours differed, while the products had variable degree of acceptability. The standardized recipes will ensure products of predictable quantity and quality.
Business Intelligence System Strategies and Organizational Success in Public Hospitals in Rivers State, Nigeria (Published)
This paper examined business intelligence System strategies and organizational success of public hospitals in Rivers State, Nigeria. The objective was to investigate the relationship between data mining, Online Analytical Processing, Querying System, Report System and organizational success of the public hospitals in Rivers State. Primary data were sourced from a sample size of two hundred and thirty four medical personnel. The test for the internal consistency of the instrument was conducted using Pearson Product Moment Correlation Coefficient (r) which yielded a reliability index of 0.89. Mean and standard deviation were used to examine the extent to which business intelligence affect performance; Spearman’s rank order correlation coefficient was used to test the null hypotheses. The findings of this study found data mining, online analytical processing, querying systems and reporting systems significantly relate to the success of public hospitals in Rivers State; there is a significant relationship data mining, online analytical processing, querying systems, reporting systems and quick decision making as well as time saving, significantly moderates relationship between business intelligence systems and organizational success in public hospitals in Rivers State. The study therefore conclude that business intelligence have significant effect on performance of the hospitals. We recommend that federal and state government should overhaul the health services and bring them into the mainstream of business intelligence scheme.
Business Benefit Concerns of Women Processors of African Locust Bean Seeds for Poverty Reduction in Enugu State-Nigeria (Published)
The study was carried out to find solution to the business benefit concern of women processors of African locust bean seeds for poverty reduction in Enugu state-Nigeria. Three research questions guided the study. Survey and Quasi-experimental design was adopted by the study. The sample for the study was 326 made up of customers from Ogbete (150), Obollo-afor (80 and Ogige (96) markets all in Enugu state. The instruments for data collection were interview schedule, counterfactual questionnaire items, interest inventory and experimental records. Data were collected by the researchers with the help of two assistants selected based on their familiarity with the study area and ability to interpret the questionnaire items in local dialects of the respondents. Percentage was used for quality analysis of the interview schedule (phase 1A), mean was used to answer research questions one (phase 1B) and three while market record was used to answer research question two. The study found out that customers rejected machine processed locust bean because of sour taste, low keeping quality and contamination among others. The study also showed that when the limitations of machine processed locust bean were eliminated through experiment, customers’ demand for the product increased which was indicated by the interest inventory data. The study therefore recommended that workshop should be organized at the local levels by extension officers for re-training of women processors and machine operators using the identified steps in the experimented processing of locust bean seeds to help overcome the business concerns of the women for poverty reduction in the Enugu state.

Effects of Various Processing Methods of Ripe and Unripe Plantain Diets on Blood Glucose Level (Published)
Ripe and unripe plantain was processed by frying, roasting and boiling. 30 human volunteers consumed individually 161g of different plantain diets prepared equivalent to 50g available carbohydrate or glucose after 10-12 hours over night fast. The venous blood samples were drawn at 30 minutes intervals for 2 hours after fasting blood glucose test. Using the glucose oxidase method, the blood glucose levels after feeding were determined. The areas under curve were calculated by trapezoid method. The glycemic index values for ripe plantain were found to be 56,54 and 55 for fried, boiled and roasted respectively while the glycemic indices for unripe plantain diets where 46, 44 and 46. For fried, boiled and roasted respectively. There were significant differences (P <0.05) in the glycemic indices of ripe and unripe plantain diets although both ripe and unripe plantain diets are within the low glycemic index range. Looking at the different processing methods the results of this study suggest that boiled unripe plantain has more promising control effect on blood glucose level and better glycemic control in carbohydrate related metabolic disorders than other processing methods.
