The effect of incorporating geogebra in cycle model of teaching calculus at university of education, Sekondi study centre

With the rapid growth of technology in the 21st century, traditional teaching and learning methods are considered outdated and not suitable for the active learning processes of the constructivist learning approach. The adjustment of existing methods and the development of new ones to teach and learn calculus with the help of technology is needed. This study aimed to investigate the effect of the use of cycle model incorporating GeoGebra software on university students’ learning of calculus in terms of proficiency in calculus and attitudes to using GeoGebra. A quasi-experiment with a pre-test post-test design and questionnaires was used. The study was conducted at a University of Education-Sekondi study center with 66 students. The data were collected over four weeks in semester two of the 2021/2022 academic year. The quantitative and qualitative data were analyzed using SPSS. The results indicated that incorporating GeoGebra in the cycle model of teaching calculus had a more positive effect on students’ conceptual and procedural understanding when compared to students who were taught using a traditional teaching approach. Students in the GeoGebra group showed greater improvement in procedural understanding, with an effect size of d = 1.2 and a percentile gain of 49%; in conceptual understanding of differential calculus. However, the students in non-GeoGebra group showed only slight improvement with an effect size of d = 0.02 and a percentile gain of 2%. Students expressed positive attitudes and perceptions towards the use of GeoGebra for learning differential calculus. While the GeoGebra oriented learning approach to calculus has the potential to improve proficiency, it remains critically important that it should be designed (cycle model) and aimed to fill a specific gap. Based on the results, it is imperatives that students are being taught calculus by incorporating GeoGebra in cycle model.

The effect of inquiry-based learning on Senior High School students’ academic performance in electricity and magnetism concepts

The purpose of this study was to explore how inquiry-based learning impacts the academic performance of senior high school students in understanding electricity and magnetism concepts. The study adopted an action research design and utilised the purposive sampling technique to select an intact class of (52) students for the research. The study sought to answer three research questions: 1. What is the effect of inquiry-based learning on students‘ academic performance in electricity and magnetism concepts? 2.What is the differential effect with respect to gender in inquiry-based learning on students‘ academic performance in electricity and magnetism concepts? 3. What perceptions do students have towards the use of inquiry-based learning approach in the teaching and learning of electricity and magnetic concepts. Data were gathered using achievement tests and questionnaire, and analysed using descriptive and inferential statistics. The findings of the study indicated that students exhibited a notable improvement in academic performance from the pre-test (Mean= 7.51) to the post-test (Mean= 11.52). The t-test analysis revealed a statistically significant difference between the pre-test mean score and the post-test mean score (p = 3.7326 x10-20, sig. at 0.05). Also, the findings revealed that inquiry-based learning approach had a positive and equitable effect on the academic performance of both male (Mean= 11.53) and female (Mean=10.56) (SHS) students in electricity and magnetism concepts. The t-test analysis of the post-test scores revealed no statistically significant difference between the mean academic performance of the male and female SHS students after being taught with differentiated instruction (p= 0.1811521, not sig. at 0.05). Moreover, the findings of the study revealed that SHS students have overwhelmingly positive views on the use of inquiry -based learning approach in the teaching and learning of electricity and magnetism concepts. In light of these findings, it was recommended that science teachers, more specifically physics teachers, should consider incorporating inquirybased learning approach to improve student learning outcomes. Teachers are urged to master various instructional methods and actively seek feedback for continuous improvement. Also, policymakers and educators should collaborate to promote widespread adoption of inquiry-based learning approach, recognizing its positive impact. Support and resources for teacher training in inquiry-based learning approach are recommended, with a focus on professional development programs. Furthermore, government and educational bodies should sponsor workshops and seminars, while curriculum planners are advised to incorporate inquiry-based learning approach in developing the science curriculum. Additionally, publishers are encouraged to produce textbooks using the inquiry-based learning format.

Effect of internal control systems on Ghanaian manufacturing firms’ performance a moderating role of internal audit effectiveness

The aim of this study is to assess the effect of internal control systems on the performance of Ghanaian manufacturing firms with a moderating role of internal audit effectiveness. A sample of 145 employees in the internal controls and audit department of the firms were used. This is a quantitative study that rides on an explanatory research design and partial least squares structural equation modelling estimation. The findings indicate that most Ghanaian manufacturing firms have been efficacious in their internal control systems. This is because they have achieved a high level of efficiency as far as their control environment as characterized by adherence to high ethical standards and organizational policies are concerned. It was further revealed that internal control system has a significant and positive effect on Ghanaian manufacturing firms’ performance. This revelation is validated by the fact that the firms’ commitment to making effective their control environment, risk assessment, control activities, information and communication and monitoring has had a significant influence on their performance. This implies that any firm having weak internal control mechanisms has the tendency of experiencing declining performance. It was finally found that internal audit effectiveness plays a significant moderating role in the causal relationship between internal control systems and Ghanaian manufacturing firms’ performance. It was thus recommended to policymakers, managers/board of directors and other key stakeholders in the manufacturing industry to institute a well formidable and resourced internal audit department necessary to strengthen the firms’ internal control systems which will eventually help improve their performance.

Effect of irregular road maintenance on the life project cycle cost (case study of government urban road in Accra municipality)

The purpose of this study was to improve key stakeholders’ understanding of the effects of irregular road maintenance on urban road project costs. The study adopted the survey research design. Quantitative research method was used to gather primary data. The population for the study was 23 consisting of Urban Roads Management experts at the Urban Roads Department in Accra specifically Okaikoi –North, Okaikoi –South, East Ayawaso and Osu-krotey. The researcher used purposive sampling technique to select 23 respondents for the study. Interview guide, questionnaires and observations were used to gather primary data. In analyzing the data collected, both the descriptive and quantitative methods were used. Tables, frequencies, percentages, Pie and bar charts were used to present and analyze data collected from the field. The key findings of the study concluded that there seems to be little acceptance that constant care of a road would result in prolonging the time when a major input of funds is required to solve the problem caused by the lack of routine maintenance. The social and economic impacts of urban roads are well established. Urban roads improve urban access, which facilitates marketing, schooling and health services. Better access provides the opportunity for increased income and employment opportunities and can also contribute to the alleviation of poverty. Still, maintenance of urban roads is seriously neglected in Ghana. Areas with poor road access are generally more disadvantaged than areas which are better served. Investments in rural roads can therefore often be justified from both a socio-economic and a poverty reduction point of view. The study recommended that, the government and development partners should invest in routine road maintenance activities to sustain the Accra Metropolis road network. The Ministry of Roads and highways should conduct periodic road maintenance

The effect of language contact on Gbi- Dzigbe dialect of Ewe

This work seeks to find out the causes of language contact in the Gbi Dzigbe community. It is also to identify the languages that are in contact with Gbi Dzigbe Dialect of Eʋe (GDDE), and whether those languages have had any effect on the GDDE, if they have, what effects have they had the on the GDDE. Data was collected through observation and interview. The indigenous people of Gbi Dzigbe (GD) were used. The study showed that Gbi Dzi Traditional Area (GDTA) is a multilingual environment, and people with different language backgrounds have settled there for economic, social, and religious reasons. Languages in contact with GDDE have some effects on the GDDE. Among the effects are lexical and structural changes. Interestingly, the dominant language in GD is being influenced by the non-Eʋe languages spoken in GD. Moreover, when indigenous people speak their language variety in a multilingual environment, they would be able to maintain their language and pass it on to the younger generations. Traditional rulers should encourage their subjects to perform the necessary traditional rites when the need arises. This will help the younger generation to acquire and use appropriate vocabulary items and expressions. Besides, this work has other linguistic researches that are related to language contact.

Effect of leadership behaviours on employee performance the case of Guinness Ghana Limited

This study was purposed to investigate the effect of leadership behaviors on employee performance. Specifically, the study identified the leadership behaviors exhibited by managers in Guinness Ghana Breweries Limited (GGBL) in enhancing employee performance and specific behaviors that affected the performance of the employees. The study was conducted with the effect of three main leadership behaviors in mind, namely, job-centeredness style, people centeredness style and democratic style on the performance of employees. The data for this study was obtained by administering questionnaire to the personnel in GGBL. The data received from the respondents were analyzed with the help of statistical software program SPSS_17. To test for the hypothesis, Pearson Coefficient correlation analysis was conducted to examine whether the hypothesis was accepted or rejected. It was observed that strong correlation existed between a job-centeredness leadership behavior exhibited by managers in Guinness Ghana Breweries Limited and it’s employee performance. The job-centeredness leadership behavior had significant positive effective on employee performance and hence productivity. It implies the managers were very particular in attaining results and thus only remunerated employees to give their best in order to increase their productivity. People-centeredness and democratic behaviors were very insignificant and a few negative correlations suggested a decrease in performance by employees, probably due to management acting with strict internal rules to achieve results. It was recommended to have a balanced leadership style to equally reflect much interest in people to enhance employee performance for a competitive advantage.

The effect of leadership styles of heads of senior high schools on teacher job performance in the Kumasi metropolis

This study sought to assess ‗how‘ leadership styles of the headmasters and headmistresses in five selected schools affect the performance of teaching staff in those schools. The study was to find ‗why‘ certain leadership styles of the heads result in certain job performances on the part of the teachers. Both qualitative and quantitative research approaches were adopted for this study. The type of question used for the interview was exploratory in nature. In terms of the quantitative aspect however, a survey approach that relied on the use of questionnaires was adopted. Two sets of instruments (Semi-structured Interview guide and questionnaire) were used in gathering data for the study. The questionnaires were distributed among the teachers of the selected schools for the needed information. The population of this study was all headmasters and headmistresses as well as teachers who teach in Senior High Schools in the Kumasi Metropolis. Five headmasters/headmistresses from the five selected study schools in the Kumasi Metropolis were chosen using the nonprobability technique of purposive sampling. Also, in selecting 230 teachers for the survey questions, the study adopted the probability sampling method of simple random sampling. The results gathered were then subjected to statistical computations using frequencies, percentages and graphs. The study concluded that if the appropriate leadership styles and positive relationships are adopted by school heads, teachers are likely to cooperate and work hard to give optimum performance that will help achieve the goals of their schools. It is therefore recommended that performance appraisal should be conducted for Senior High School heads and their teachers in a regular fashion to provide a ready reference on the performance of each school.

Effect of locally available phosphorus sources on soil phosphorus fractions, phosphorus uptake, maize dry matter production and grain yield on a typic plinthustuulf

The study was conducted to assess the effect of different locally available phosphorus sources on agronomic P use efficiency, P utilization efficiency, P recovery efficiency, total dry matter production, grain yield of maize and soil P fractions in a locally available amended Typic Plinthutuuf in 2017 and 2018 minor cropping seasons. The study involves nine treatments each replicated three times in a Randomized Complete Block Design (RCBD). The treatment combinations were: No amendment (T1), 1.30 kg/ plot Urea+ 1.92 kg/ plot TSP + 0.38 kg/plot KCl (T2); 49.56 kg/plot EFB Mulch + 0.25kg/plot Urea + 1.03 kg/plot TSP (T3) , 24.80 kg/plot EFB Mulch + 0.25kg/plot Urea + 20.16kg/plot EFB Compost+ 1..05 TSP (T4), 53.76 kg/plot RH Biochar + 0.19 kg/plot Urea + 1.38 kg/plot TSP + 22.68 kg/plot EFB Compost (T5), 28 kg/plot EFB Mulch + 28 kg/plot RH Biochar+ 0.19 kg/plot Urea+ 1.25 kg/plot TSP (T6), 40.6 kg/plot EFB Compost + 0.25 kg/plot Urea + 1.3 kg/plot TSP (T7), 49.2kg/plot RH Biochar + 28.08 kg/plot EFB Compost + 1.91 kg/plot RP (T8) , 21.3 kg/plot EFB Mulch + 28.08 kg/plot EFB Compost + 1.15 kg/plot RP (T9). The data were analyzed by ANOVA and LSD at 5 % level of significance was used to separate the means. The maize grown on T2 enhanced the highest agronomic P use efficiency and grain yield in 2017 as well as total dry matter production and growth parameters in both 2017 and 2018. T5 was also observed to promote maize plant with the highest total P uptake and P recovery efficiency in both 2017 and 2018 minor cropping seasons. The highest soil P fractions, the soil properties as well as the P utilization efficiency and the P harvest index were obtained from organic P sources and integrated P sources. Across all the treatment, maize plant performed better in 2018 minor cropping season than in 2017 minor cropping season probably due to the higher rainfall and temperature in 2018. In conclusion, the application of NPK, rice husk boichar and its compost and rock phosphate promoted the highest grain yield and total dry matter production and therefore is recommended for adoption by all farmers.
