    Occupational Health, Safety, and Injuries among Firefighters in the Western Region of Ghana.
    (ACQUAH, Jonas, 2024-07) ACQUAH, Jonas
    The Ghana National Fire Service (GNFS) was established in 1963 by Act 219 primarily engages in firefighting, extinguishment, and humanitarian services. This study assessed occupational health, safety, and injuries among firefighters in the Western Region of Ghana, drawing from a sample of 270 respondents. The research employed a descriptive cross-sectional design to assess the prevalence of occupational injuries and associated risk factors, and the effect of first-aid training programmemes on occupational health and safety. The key findings revealed that 28.5% of firefighters reported experiencing work-related injuries, with activities such as fighting fires (34.1%) and handling tools and equipment (18.3%). Despite the prevalence of injuries, 45.1% of firefighters took no days off due to their injuries, underscoring potential challenges in injury management and rehabilitation. Work related health issues are also prevalent among firefighters, with 31.9% experiencing post-traumatic stress disorders and 26.3% reporting sleep troubles. While health and safety policies exist within the GNFS, disparities in implementation and adherence are apparent. Notably, while 52.6% of firefighters reported the presence of a documented health and safety policy, only 13.0% indicated having enough personal protective equipment (PPE) for all workers. First aid training emerges as a crucial aspect, with 84.8% of firefighters believing it is essential to learn first aid, and 83.3% agreeing that first aid should be given quick attention in the workplace. However, exposure to biological and chemical hazards underscores the need for continuous training and stringent safety protocols. In conclusion, this study provides valuable insights into the occupational health and safety challenges faced by firefighters in Ghana's Western region. The findings underscore the importance of targeted interventions to enhance workplace safety, injury prevention, and emergency response strategies within the firefighting profession. Policymakers and fire service authorities can utilize these findings to implement measures aimed at ensuring the well-being of firefighters and the efficacy of firefighting operations. Further research is warranted to delve deeper into specific aspects of firefighter safety and health, facilitating continuous improvement in occupational safety practices and operational effectiveness.

    Occupational Health Hazards and their Associated Risks among Medical Emergency Staff in the Western North Region of Ghana.
    (MANU, Prince, 2024-04) MANU, Prince
    Healthcare workers, specifically medical emergency staff, are continuously exposed to disease-causing pathogens, especially blood-borne pathogens. Occupational health and safety adherence helps to prevent the risk of illness and death associated with exposure. Unfortunately, in most Sub-Saharan African countries including Ghana, there are problems with the limited healthcare workers, which has led to overuse of the workforce. This situation is worsened by the frequent shortage of surgical and other hazard-prevention equipment especially in high-risk settings such as the medical emergency ward. This study assessed occupational health and hazards and their associated risk among medical emergency staff in the Western North region of Ghana. This hospital-based cross-sectional study included 390 medical emergency staff working in either government or private hospitals in the Western North Region of Ghana. A well-structured questionnaire was used to collect data on socio-demographic, and occupational health hazard risks exposures and outcomes. Statistical analyses were done using SPSS version 26.0 and Graph-Pad prism 8.0. p < 0.05 was considered statistically significant. This study found that, over ninety percent of participants wore personal protective equipment (PPE) in all procedures (99.5%), followed standard operating procedures (96.9%), reported exposure to occupational health hazards (91.5%) and rate good personal occupational health practice (91.5%) at the work place. Majority had good occupational health and safety practice representing a proportion of 71.0%. Regardless, over ninety percent (96.7%) had been exposed to occupational health hazards and this call for in-depth studies.

    Comparative Study Of The Mr-Sr Based Pimca Model And The Conventional Approach On Students’ Performance And Attitude In Optics
    (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 Concepts Achievement 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 post intervention (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.

    Comparative Effects Of 5E, Differentiation, And Conventional Teaching Methods On Physics Students’ Academic Performance In Thermal Physics
    (2023-11) DARKO ATEKO, Kenneth
    In this study, the comparative effect of 5E Instructional Model, Differentiated Instruction and conventional teaching method on Senior High School (SHS) Physics students’ academic performances in Thermal Physics was investigated. Employing a quasi experimental pretest/posttest non-equivalent control group design, 291 SHS 2 Physics students were employed from six intact classes from 3 randomly selected Senior High Schools in the Mampong Municipality and Sekyere South District. The instrument used for data collection was Thermal Physics Concepts Test (TPCT). The hypotheses were tested using independent sample t-tests, one-way ANCOVA and two-way ANCOVA at α=0.05. The results indicated that, SHS students taught using 5E Instructional Model performed better (M=16.59, SD=5.168) than those taught using conventional teaching method (M=13.34, SD=5.010; t(191)=4.437, p=0.000<0.05). Similarly, SHS students taught using Differentiated Instruction performed better (M=19.12, SD=5.766) compared to the conventional teaching method (M= 13.34, SD=5.010; t(188)=7.362, p=0.000<0.05), and also compared to the 5E Instructional Model (F(1,196)=34.833, p=0.000), after introducing the interventions. However, there was no significant difference in academic performance between male and female SHS Physics students taught using Differentiated Instruction (mean difference=0.233, p=0.765) and 5E Instructional Model (mean difference=0.75, p=0.532), but a significant difference in academic performance between male and female SHS Physics students taught using conventional teaching method (mean difference=8.284, p=0.000). It was therefore recommended, amongst others that SHS Physics teachers should consider Differentiating their students in order to tailor Physics lessons to all students, which will help them perform better in Thermal Physics.

    Inadequate Science Practical Activities In Basics Schools: Impact On Performances Of Students In Integrated Science Education In Senior High Schools
    (2023-12) ADDAI, Sarah
    This study sampled students from three Senior High Schools and science teachers from four basic school in the Old Tafo Municipality for different levels of assessments through questionnaires. Descriptive statistics of frequency counts and percentages were used to analyse the demographic data of the respondent while chi-square test and Pearson corelation test were used to test the impact of science practical lessons in Junior High Schools on performances of students in science in Senior High Schools. Chisquare test and Spearman correlation indicated a significant effect of exposure to science practical lessons in basic schools on student’s ability to do simple practical lessons in Senior High Schools. Results from the responses showed that many Basic Schools do not have some basic scientific equipment. Moreso, there are inadequate field visits, test books and practical guides to support science practical lessons. Inadequate science periods, teachers’ low confidence in some selected science practical topics and large class size of some schools are hindrances to the success of science practical lessons in the Basic Schools. Students who do not get access to practical lessons in Basic Schools are over-shadowed by their other counterparts in the Senior High School science lessons and therefore individual students need proper exposure in Basic Schools before they enter Senior High Schools. Community science laboratories are needed for students to do supplemental practical activities during and after school hours. Stakeholders and other agencies in the education sector need to supply enough science equipment in Basic Schools to increase pupils’ interest in science and then properly adjust them for senior High education.
