    Synthesis, Characterization and Application of Activated Carbon Nanotubes in Removal of Pb, As, and Cd in Groundwaters in Berekum Municipality of Ghana.
    (ANTEPIM, Yeboah Samuel, 2025-09) ANTEPIM, Yeboah Samuel
    Safe, convenient, and cost-effective method of treating water to meet the drinking water needs of human is the key responsibility of upcoming scientist. Heavy metal contamination in water poses significant global challenge affecting both developed and developing nations due to their detrimental effect and health injuries on human and other organisms in the ecosystem. Carbon nanotubes has received the attention of researchers in water treatment and has been detailed premeditated in salt removal, heavy metal removal, removal of cosmetics, removal of antibiotics, removal of potentially toxic elements, and microorganism removal in drinking water. This investigation synthesized carbon nanotubes from graphite powder to remove Pb, As and Cd from ground water. Characterization with SEM, FTIR, UV-VIS and XRD showed polydisperse distribution of carbon nanotubes with particle sizes between 0.0553 µm (55.3nm) to 4.480 µm (480nm). UV showed multiwalled carbon nanotubes and XRD suggested moderate crystallinity. Synthesized carbon nanotubes showed effective adsorbent for removal of selected metal with removal rates of 95.36%, 96.3% and 94.33% for Pb, As and Cd respectively. The adsorption of Pb was best described by the Lagmiur isotherm model whereas the Freundlich isotherm model provided a better fit for As and Cd adsorption, as evidenced by coefficient if determination and chi-square error analysis. The activated carbon nanotubes have exhibited effective adsorption capacity for heavy metal treatment in water with higher maximum adsorption capacity which shows effective treatment of large volumes of water with higher metal contamination. The study suggest that activated carbon nanotubes will be used for water treatment for public due to economic feasibility and environmental sustainability.

    (2023-11) Iddrisu Abdul-Aziz
    The purpose of the study was to explore teacher motivation and its impact on teacher’s retention in Mankranso Senior High School in the Ahafo Ano South District. The objectives of the study were to find out motivational packages existing for teacher, determine how motivational packages affect teachers’ performance and to establish motivational packages that promote teacher retention. A descriptive survey design was used for the study. The population for the study was teachers. The sample size was 90 teachers. Purposive sampling method was used to select all the 106 out of which 90 teachers responded. The reliability test yielded Cronbach Alpha of 0.79. Structured questionnaire was used as data collection instrument for the study. Descriptive statistics were used to analyse the data. The study found that motivational packages existing for teachers include, regular training programme and teachers’ empowerment. Motivational packages that promoted teacher retention were training, education and development and congenial working environment. It is recommended District Directors of Education should organize regular training sessions for teachers to build their capacity to motivate teachers to remain in the service to perform better. Again, he Ahafo-Ano South District Directorate of education should liaise with heads to apply the measures the study revealed to improve motivation in senior high schools.

    Comparative study of the Mr-Sr Based Pimca Model and the conventional approach on students’ performance and attitude in optics.
    (TANKO, Simon, 2024-11) TANKO, Simon
    The study compared the MR-SR Based PIMCA Model and the Conventional Teaching Approach on academic performance and Attitude of Senior High School Physics Students in optics in Mampong Municipality and Sekyere South District, both in the Ashanti Region of Ghana. This research study employed the non-equivalent groups pretest-posttest quasi-experimental design. Samples of 164 SHS two Physics students drawn from four intact classes were used for the study. Two research instruments, known as Optics Concepts Achievement Test (OCAT) and the Optics Learning Attitude Questionnaire (OLAQ) were used to gather data for the study. The study comprised of one research question and three hypotheses. Descriptive statistics such as mean, standard deviation and mean difference were used to answer the research question, while one-way between groups analysis of covariance (one-way ANCOVA) was used to test the hypotheses. The results revealed that students taught using MR-SR Based PIMCA model performed better in the Optics ConceptsAchievement Test (OCAT) than those taught using conventional approach (F(1,161)= 129.090, p=0.000<0.05). There was no gender (F(1,72)= 0.319, p=0.574>0.05) and ability (F(1,49)= 0.44, p=0.835>0.05) differences in academic performance on the use of MR-SR Based PIMCA model. It was also found from the pre-intervention (M= 1.0531, SD= 0.06033) and postintervention (M=3.7686, SD=0.12531) questionnaire responses that the PIMCA model enhanced students’ positive attitude towards Physics. Using the Model was concluded to be more effective than the conventional teaching approach in enhancing SHS students’ academic performance and attitude in optics. It was therefore recommended among others that Physics teachers in the Mampong Municipality and Sekeyere South District should use the MR-SR Based PIMCA model to teach optics and other challenging Physics concepts in the Senior High School.

    (2023-09) Henry Osei
    The purpose of this study was to investigate the impact of school inspection on senior high school students’ academic performance. The target population were workers of the National Schools Inspectorate Authority (NaSIA) – Ejisu district, and teachers of public senior high schools in the Ejisu district which are Ejisu/Technical Senior High School and Church of Christ Seinor High School. The total number of these workers were 155. Random sampling aided in the selection of one hundred and one (111) workers from the population as respondents for this study. The research design used for their study was quantitative method. The study adopted the descriptive approach with quantitative approach to gather and analyze relevant data by means of quantitative approach. The descriptive statistics were employed to analyze the quantitative data. Based on the objectives of this current study, it was concluded that there was a positive rate concerning the characteristics of schools’ inspectors assigned to assess the school. Lastly, there was an impact of inspection on academic performance of senior high school students. There were challenges to the professionalism of school inspectors. The study recommended that feedback to the school be promptly provided by the school inspectorates, School inspection regulations demand that inspection reports be sent to all stakeholders within two weeks after the inspection. It was further suggested that the budget for school inspection should be increased by the government, School heads and academic coordinators felt that more money should be set aside for school inspection.

    (2023) Haruna Fatah Seinu
    The purpose of the study was to look into the management strategies used by junior high school headteachers in Ghana's Upper East Region's Builsa South District. The study aimed to find out headteachers' management practices, identify obstacles they encounter in managing junior high schools, and analyse strategies for enhancing headteachers' management practices in junior high schools located in the Builsa South District. Descriptive survey design using quantitative approach was adopted. All junior high school headteachers and assistant headteachers and teachers were the target population. The 46 headteachers and assistant headteachers and the 23 teachers made up the accessible population. The schools and each of the 46 headteachers and assistant headteachers were chosen through the use of census sampling. A closed-ended questionnaire was used by the researcher. Cronbach Alpha was found to be 0.86 in the reliability test. Frequencies and percentages were used in the analysis of the data. The results of the study showed that headteachers fostered a supportive environment in which educators were encouraged to reach their full potential in order to impart knowledge to students and, when needed, assign tasks to other educators. Managing junior high schools also presented difficulties due to a lack of finance, inadequate educational facilities, and an unsustainable workload. Enhancing junior high school headteachers administration can be achieved through offering rewards such as gift and citation, giving frequent feedback, and showing respect for each individual employee. To address the numerous issues facing headteachers in Builsa South District, it is recommended that the Ghana Education Service and the Builsa South District Directorate of Education should collaborate to equip headteachers of junior high school with good management practices and skills
