Strategies and Procedural and Conceptual Knowledge of Addition of Unlike Denominator Fractions: The Case of Grade 8 Children in Two Districts of the Central Region of Ghana

By Ebo Amuah

This study investigated children’s knowledge of the addition of fractions with unlike denominators. It focussed on the strategies used by children to add fractions with unlike denominators. A cross-sectional survey of Grade 8 children in schools in two districts in Ghana was used. A test on the addition of fractions with unlike denominators was administered to 543 high-, average- and low-achieving children, and their responses were categorised based on the characterisation of correct strategies by Braithwaite et al. and Siegler and Pykes. Cluster bar charts and analysis of variance were used to analyse the data. The results showed that the children’s use of correct strategies for adding proper fractions with unlike denominators was higher than their use of correct strategies for adding improper fractions with unlike denominators. Thus, the children’s procedural knowledge of the addition of proper fractions with unlike denominators was higher than that of improper fractions with unlike denominators. Conceptual knowledge of the addition of fractions with unlike denominators was much lower than procedural knowledge of the same. The less advantaged (females, rural and low achievers) used fewer correct strategies and demonstrated less procedural and conceptual knowledge. Among other recommendations, curricula and classroom teaching should emphasise conceptual knowledge and its support for procedural knowledge of the addition of fractions with unlike denominators. Research interventions focussed on the less advantaged are advised. © 2023 Southern African Association for Research in Mathematics, Science and Technology Education (SAARMSTE).

Exploring preservice teachers' digital skills, stress, and coping strategies during online lessons amid covid-19 pandemic in Ghana

By Christopher Yaw Kwaah

There are concerns about the association between the level of students' digital skills and the amount of stress they experience. However, evidence from both cross-sectional and longitudinal studies is limited. The main aim of this study was to address this gap in the literature by examining the relationship between preservice teachers' digital skills and stress. The study employed an online cross-sectional survey, which was completed by 661 pre-service teachers enrolled in colleges of education in Ghana. The findings showed that preservice teachers' low digital skills were associated with higher stress levels during the period of online teaching and learning necessitated by the COVID-19 pandemic. The study further revealed that preservice teachers' limited access to resources was a significant cause of stress. Preservice teachers' main coping strategies for reducing stress were positive framing, such as seeking advice from friends and family, seeing something good in what is happening and learning from the experience. Recommendations include providing more training on digital technologies during the initial preparation for teachers.
