2024-06-24T21:17:10+00:00

Effective utilisation of technology in the classroom relies on, among other factors, the roles, and actions of teachers, considering both opportunities and limitations presented by technology in representing the subject matter. Therefore, it is essential to examine the pedagogical practises employed by teachers when using technology to teach science. By use of an explanatory case study design with qualitative data sources such as focus group interviews, lesson artefacts and observations, this research adapted the Technological Pedagogical and Content Knowledge (TPACK) framework as a lens within a professional development framework to examine the pedagogical context of four prospective teachers as they designed and implemented simulation-based physics lessons in pairs. The objective was to gain in-depth understanding of the pedagogical support structures necessary for successful implementation of Physics Education Technology (PhET) simulation-based physics lessons, with a focus on promoting a learner-centred instructional approach in Ghanaian science classrooms. The findings suggest that the provision of minimal guidance through activity sheets, as well as facilitative strategies such as engaging prior knowledge, supervising learner activities, fostering discussion platforms and providing summaries, are crucial pedagogical support structures that drive learner-focused instructional processes when using simulations. The study advocate that central to the success attained with simulation-based lessons was the prospective teachers’ developed TPACK as well as the content-sensitive and interactive affordances offered by PhET simulations, despite acknowledging their inherent limitations as technological tools.

2024-06-24T21:26:05+00:00

Problem-based learning is a student-centered, inquiry-based instructional model in which learners engage with authentic, ill-structured problems that require further research. This study sought to find out the impact of problem-based learning approach to teaching on senior high school students’ performance in solving simultaneous linear equation word problems. The study employed a quasi-experimental research design in which 103 second year science students were randomly sampled from four senior high schools and assigned to a control group (n=51) and an experimental group (n=52). Data were gathered using tests (pre-test and post-test) and analyzed using descriptive and inferential statistics. The study revealed that many SHS students performed poorly in solving word problems involving simultaneous linear equations. This was established from the fact that about ninety-eight (98) of the students representing 95.1%, scored less than half of the total score (100) in the pre-test. However, students that were exposed to Problem-based learning approach of teaching mathematics performed better in the post-test than those taught by the Traditional approach. This suggested that Problem Based Learning has positive effect on students’ performance in solving word problems involving simultaneous linear equations. The study therefore concluded that Problem Based Learning is a more effective approach, which mathematics teachers as well as other subjects’ area teachers need to incorporate into their teaching.

Continuous professional development (CPD) is crucial for enhancing the teaching profession. Biology teachers have gained knowledge, skills and competencies through CPD programs to improve learning outcomes. This study examined the perceptions of biology teachers regarding CPD programs in 12YBES of Kirehe district, focusing on their views, the barriers they face, and possible solutions. It, therefore, aimed to provide the biology teachers’ perception towards CPD programs, barriers and remedies. A mixed methods approach was applied, involving 20 head teachers and 46 biology teachers from 12YBES. Data were collected using questionnaires, interviews and secondary sources, and analyzed using SPSS. The findings revealed that 94% of biology teachers perceived that CPD programs strengthened their teaching methodology and conseqontly impacted their learners’ biology learning outcomes. However, remarkable barriers were identified including shortage of learning aids (61%) and lab equipment (20%). This study highlighted the importance of CPD but not fully utilized, recommending expanded CPD activities across all sectors to improve learning outcomes.

Attitudes and Metacognitive Awareness as Predictors of Undergraduates’ Algebra Scores

2024-09-14T09:07:22+00:00

Research examining students’ attitudes and awareness of how to learn mathematics and their effect on performance is still inconclusive. The study examined the relationship among first year students’ attitudes towards learning algebra, metacognitive awareness and algebra performance at a university in Ghana. Two inventories were adopted and used to collect data from an intact class of 180 first year mathematics education students. These students' end of semester examination scores in first year algebra were used to indicate their performance in algebra. Data was analysed using descriptive statistics, correlation and linear regression analysis at .05 significance level. On the four subscales of attitude, the result shows significantly weak negative relationships between students’ self-confidence and algebra scores, as well as students’ enjoyment for algebra and algebra scores. Also, there was significant positive relationship between students’ metacognitive awareness in algebra and algebra scores. However, students’ value of algebra and motivation were not statistically related to their algebra scores. The regression analysis indicated that students’ attitude towards the learning of algebra (self-confidence and enjoyment) and metacognitive awareness levels predicted students’ scores in algebra. The findings suggest the need for algebra lecturers to enhance first year students’ metacognitive skills and positive attitudes as bases for boosting performance in algebra. The implication, for lecturers providing orientation to first year students on how to learn to think algebraically in their first lecture, is highlighted.

2024-09-20T20:42:25+00:00

Metacognitive learning refers to the process of being aware of and taking control of one's own learning. The effective use of metacognitive learning strategies (MLS) can lead to improved student learning outcomes. It helps student to set SMART goal, monitor their own progress, encouraging students to reflect on their own learning and providing feedback that is specific, constructive, and timely can help students to identify areas where they need to improve. The study focused on mathematics/science student’s metacognition utilization in Colleges of Education in Volta region of Ghana. Of 323 population, 139 were sampled for the study using quantitative exploratory cross – sectional survey design. Twenty – five question items using Metacognitive Learning Utilization Questionnaire (M-LUQ) relating to planning, monitoring, evaluation, self-regulation and comprehension was used for data collection. The latent class analysis (LCA) suggests the three-class solution as the accepted best fitting model, based on statistical fit indicators AIC, BIC, entropy, Gsq, and Chsq. The result revealed that comprehension, monitoring and evaluation were very good, and averagely good respectively utilised by majority while self – regulation and planning were satisfactorily and poorly utilised by students. The variables were tested using one way ANOVA with high, moderate and low-level utilization. There was a statistically significant difference between all three-class based on the mean. The study indicate that comprehension was highly utilized while planning was the lowest utilized component (MLS). Is therefore, recommended student should be supported with metacognitive learning awareness with focus on planning and self-regulation. Other implications of the findings are discussed.
