ABSTRACT

The study was designed to identify the strategies for enhancing the teaching of Foundry technology in Polytechnic. The study is a survey research design. A structured questionnaire of different strategies for teaching was used for data collection and was administered to 79 teachers of Foundry technology in Kano state Polytechnic, Kano.  Based on the findings conclusion was drawn that the respondents accepted the needs for instructional strategies for enhancing the teaching of Foundry technology in Kano state Polytechnic, Kano. As this will result to producing Polytechnic graduates who are apart from been self-reliant and enterprising will also be jobs providers.Keywords: Strategy, Enhancing, Foundry Technology, Polytechnic

ABSTRACT         

The issue of failure in mathematics especially in the mensuration content of the curriculum despite its practical nature has been of great concern to all stakeholders of mathematics education. This study therefore investigated the difficulties that senior secondary school students encounter while solving problems in mensuration and the influence of gender on the level of difficulty experienced. The study adopted a descriptive survey design using quantitative methods. The sample consisted of 270 SS II students, (of which 144 were males and 126 were females) from two Education Districts in Lagos State.  Three instruments; students’ diagnostic test in mensuration, questionnaire in mensuration for students and questionnaire in mensuration for teachers with reliability coefficients of 0.82, 0.76 and 0.88 respectively were used for data collection. Data collected were analyzed using both descriptive and inferential statistics. Results showed that students’ level of understanding in mensuration was low. It was found that the numerous difficulties that students encounter generally fall into categories; formulae, concept, language and procedure, and skills related difficulties. Acting subtly and indirectly compounding the level of difficulties encountered were some affective factors categorized as psychologically related difficulties. However, gender did not significantly influence the level of difficulty encountered. It was recommended that mathematics teachers should pay attention to these students’ difficulties during instruction. This will enable them to tackle the difficulties and consequently improve students’ achievement in mensuration and by extension, in mathematics.Key words: difficulties, mensuration, problem solving, gender

ABSTRACT

Dimensional analysis is a way of simplifying a physical problem by appealing to dimensional similarity to reduce the number of relevant variables. A multi-parameter problem often has    difficulties in achieving complete similarity.Dimensional analysis gives a useful technique of decreasing difficult physical problems to the easiest, simplest and most economical method before obtaining a measurable solution. This study worked on getting the pi terms or groups involved in two geometrically similar tanks allowing the fluid (water) to be completely drained from them using two temperature values of 26.5℃ and 43.5℃ respectively for each tank using n relevant variables and m independent dimensions which was reduced to a relationship between   n – m non-dimensional parameters , …, . As the values of pi 1 ( terms of the big tank are decreasing, the values of the pi 4 terms are increasing in all cases.

Keywords: Dimensional analysis, Similar tanks, temperature, pi-terms, Measurable, Technique.

ABSTRACT

In this study, the stochastic price movements of stocks are modeled by a geometric Brownian motion (GBM). The model assumptions of the GBM with drift: continuity, normality and Markov tendency, were investigated using four years (2015 – 2018) of historical closing prices of ten stocks listed on The Nigerian Stock Exchange. The sample for the study is based on the eight sectors of The Nigerian Stock Exchange and most continuously traded stocks. The predicted stocks prices have been compared to actual prices in order to evaluate the validity of the prediction model. On stocks prices prediction using geometric Brownian motion model, the algorithm starts from calculating the value of returns, followed by estimating values of volatility and drift, obtaining the stock prices forecast, calculating the forecast Mean Absolute Percentage Error, calculating the stock expected prices and calculating the confidence level at 95%. The results show that the value of the MAPE is 50% and below for the one to two year holding periods, and above 50% for the three year holding period. The MAPE and directional prediction accuracy method provided support that over short periods the GBM model is accurate. Meaning that the GBM is a reasonable predictive model for one or two years, but for three years, therefore, it is an inaccurate predictor.

ABSTRACT

This study aims to examine the effect of human resource management practices on employee turnover intentions among medical practitioners in Nigerian public hospitals. The population of the present study consisted of 1,570 medical practitioners who work in Nigerian public health facilities in Abuja, Niger, and Nasarawa states. Also, simple random probability sampling technique was adopted. The participants returned almost all the distributed questionnaires but 310 questionnaires were valid and used for analysis with statistical package for social sciences (SPSS) used for data analysis. Results demonstrate that employee training is negatively related to turnover intentions. This suggests that a well-trained employee may wish not to leave the hospital. Also, results indicate that a fair and competitive compensation practice may discourage medical practitioners from quitting their employment. This suggests that a well-paid medical practitioner may stay longer than those who are not satisfied with their level of pay. Based on the findings of this study, it is recommended that both federal and state ministries of health need to appraise the HR policies being implemented in various government hospitals to avoid cases of brain-drain. More so, lingering issues bothering on allowances and unpaid salaries in some government-owned hospitals must be attended to. Hence, the researcher concludes that HR policies on employee training and compensation practice are relevant in mitigating turnover intentions among medical practitioners in government hospitals.

Keywords: employee turnover intentions, employee training, compensation practice, and performance appraisal.
