Comparative effect of collaborative peer and video-based microteaching models on selected female preservice teachers’ science teaching efficacy Awortwe, L. microteaching models in enhancing the science teaching efficacy of selected Ghanaian female preservice teachers. A comparative research design with purposive (criterion-based) sampling was used to select two intact classes comprising fifty-six (56) second-year Early Grade preservice teachers from the Presbyterian Women’s College of Education, Aburi. Participants were assigned to two treatment groups: collaborative peer microteaching and video-based microteaching, with twenty-eight (28) participants in each group. Over a period of six weeks, participants engaged in their respective microteaching sessions. Data was collected using the Science Teaching Efficacy Beliefs Instrument (STEBI-B), the Perception of the Collaborative Peer Microteaching Model (PCPM) questionnaire, and a focus group interview. The STEBI-B was administered as a pre-intervention and post-intervention assessment to measure science teaching efficacy before and after the interventions. Paired-sample ttests showed significant improvements in STEBI-B scores for both the collaborative peer group (t(27) = −3.167, p = 0.004 < .05) and the video-based group (t(27) = −7.906, p = 0.000 < .05), with the larger t-value indicating that the video-based microteaching model was comparatively more effective. An analysis of covariance (ANCOVA) further confirmed that when the collaborative peer and video-based microteaching groups’ pre-intervention STEBI-B assessments are controlled, the video-based microteaching was comparatively more effective in enhancing female preservice teachers’ levels of science teaching efficacy. A two-way ANCOVA also revealed that age, prior teaching experiences, and their interaction had no statistically significant effect on participants’ STEBI-B scores. Additionally, responses from the PCPM questionnaire and focus group interviews indicated that participants generally perceived both microteaching models as effective in enhancing their science teaching efficacy.

Exploring science teachers’ instructional practices across regular, inclusive, and deaf basic schools in Ghana- a multiple case study Osei, J.K. Science education remains central to Ghana’s national development agenda, yet concerns persist regarding how effectively science is taught at the basic school level, particularly within diverse learning environments. Despite curriculum reforms and inclusive education policies, disparities in instructional practices are evident across regular, inclusive, and special schools for the deaf. Limited empirical research has systematically examined how science teachers in these varied contexts plan, deliver, and assess instruction, and how their practices respond to the unique needs of learners. This study therefore set out to explore the instructional practices of science teachers in a regular basic school, an inclusive basic school, and a school for the deaf in Ghana, with a view to identifying strengths, challenges, and context-specific implications for improving science education. A phenomenological research design was adopted to understand and describe the lived experiences of individuals. Semistructured interviews and observations were used for data collection. The sample comprised 30 individuals, including teachers and interpreters from the targeted schools, with data saturation guided by the richness and quality of the data collected. The findings revealed that science teachers possessed varying academic qualifications, from Diplomas to Master's Degrees, influencing their preparedness for teaching. Teachers emphasized the importance of planning, delivery, and assessment in their instructional practices. Regular schools primarily used lecture-based teaching, inclusive schools adapted methods to diverse learning needs, and deaf schools relied on visual aids and sign language. Teachers in inclusive classrooms employed multimodal approaches, individualized instructions, and technology integration, despite challenges like time constraints and resource limitations. There was a significant discrepancy between reported and actual usage of assistive technologies, with barriers like cost and maintenance limiting their effectiveness. Capacity-enhancing activities, including INSET workshops, were crucial but required more specialized training and regular refresher courses. The study recommends that educational authorities and school administrators should collaborate to provide ongoing professional development specifically tailored to the unique demands of inclusive and deaf education. The Ministry of Education and the Ghana Education Service should develop frameworks and support systems that encourage and facilitate further individualization of instruction. This includes organizing professional development workshops focused on advanced differentiated instruction techniques and creating resources to help teachers effectively tailor their teaching strategies to meet individual student needs.

Evaluation of the chemistry curriculum implementation in Senior High Schools in the Eastern Region of Ghana Sedegah, S. This study evaluated the classroom implementation of the Senior High School elective chemistry curriculum in the Eastern Region of Ghana. A cross- sectional descriptive survey design was used for the study. The target population comprised all the public Senior High Schools in the Eastern region of Ghana that offered elective chemistry. The accessible population consisted of seventy-one public Senior High Schools out of which 21 schools were selected making up 30% of the accessible population. The schools were selected through purposive sampling from ten districts and municipalities in the Eastern Region. A random sample of 366 students offering General Science in form three were involved in this study. There were 73 chemistry teachers, 21 HODs science and 21 assistant heads for academics in the selected SHSs who were purposively selected to be part of the research. The chemistry teachers and chemistry students chosen have used the curriculum materials extensively in the teaching and learning process not less than two years. The main instruments used for the research were interview, observation and questionnaire and document analysis. The data from questionnaire was analysed quantitatively using SPSS version 22 and the data from interview guide, observation guide and document analysis were analysed qualitatively. The findings revealed that most teachers who were the chemistry curriculum implementers had the required academic and professional qualifications needed to implement the chemistry curriculum. However, there were a few teachers without the required qualifications. The findings showed that there were dedicated laboratories for chemistry practical. However, there were major challenges associated with the adequacy of facilities and chemicals. The lessons observed were typical teachercentred. The focus of the lessons were on the transmission of knowledge from the teacher to the students. The study found that the challenges of chemistry curriculum implementation identified by both teachers and students involved in the study were overloaded chemistry content, large class sizes, inadequate chemistry teachers, inadequate instructional resources, and inadequate practical activities. It was recommended that the SHS institutions should allocate dedicated time slots within the school timetable for practical activities. This would help teachers to engage students in practical activities regularly. There is a need for the government and stakeholders to join hands to build well-equipped laboratories with adequate chemicals and necessary facilities such as water, electricity. It is suggested a study should be conducted to assess how teacher training programmes influence the quality of SHS chemistry curriculum implementation. Also, survey should be conducted to explore the relationship between the implementation of the SHS chemistry curriculum and students' academic achievements in chemistry.

Using Culturo – Techno Contextual Approach (CTCA) to enhance upper primary pupils’ performance and knowledge retention in science Dabanka, C.P. This study explained how the Culturo Techno Contextual Approach (CTCA), a method of teaching, could help to enhance pupils in upper primary six performance and knowledge retention in science. The research design used was the action research under the spiral model touted by Kemmis and McTaggart. The mixed method study approach was considered adequate for the study. The targeted population included all the primary six pupils and teachers in the Kumasi Metropolitan area but the accessible population consisted of upper primary six teachers from the old Tafo M/A primary B school in the old Tafo submetro in the Kumasi Metropolis. The sample size was 52 pupils who happens to be the entire class size of class six. The instruments used were document analysis, test, observation and interview schedules. The study involved three main intervention stages during the data collection procedure, the pre - intervention, intervention and postintervention. Five lessons on selected science concepts were designed and taught using the CTCA. Five craftsmen, three women and two men were interviewed on their indigenous economic activities to determine the science processes and the science concepts that were associated with each. Data collected was put into themes and analysed. The finding of the study suggested that there are several indigenous economic activities in the research area and its environs and for each one there were science processes and concepts associated with it. Some of the identified indigenous activities are charcoal burning, palm oil preparation, pito brewing and craft and artisanal production. Each of these activities were associated with indigenous processes. For instance, charcoal burning is associated with indigenous processes such as cutting of wood, arrangement of wood, covering of wood with leaves and burning of wood. The study again identified some specific skills that were inculcated in the learners during the use of the CTCA. The skills were grouped as basic and integrated skills. The basic skills identified were observation, communication and classification, and the integrated also included cultural sensitivity, technological integration and contextual understanding. The study indicated that pupils' conceptual understanding and retention of the concept taught using the CTCA improved based on the pre and post test scores obtained. Based on the findings of the study, it was recommended that community involvement in curriculum design must be encouraged, and indigenous knowledge must be integrated into the basic school science curriculum.
