Moving beyond the 'one-size-fits-all' approach to assessment practices in South African Grade 10 classrooms: The case of a Johannesburg based school

Abstract

Traditional ‘one-size-fits-all’ assessment approaches remain the predominant assessment methods used in South African classrooms, which is problematic in a country marked by rich cultural, linguistic, and socio-economic diversity. Conventional assessment practices often fail to accurately reflect the full spectrum of learners’ abilities, which in turn poses a barrier to effective teaching and learning. This study explores the use of differentiated assessment strategies as a means to accommodate the diverse needs of learners in Grade 10 classrooms. The overall objective of the study was to explore how differentiated assessment can be utilised to improve learning outcomes and better meet the diverse needs of Grade 10 South African learners at a Johannesburg-based high school. This study focuses on three objectives, which include exploring teachers’ perceptions of differentiated assessment, identifying potential problems faced when implementing differentiated assessment, and investigating and understanding the support required by teachers to make this assessment approach viable in practice. The study is located within an interpretivist paradigm. A qualitative research approach was adopted, employing a case study design to allow for an in-depth exploration of the issue within its real-world context. Participants were selected using a four-step sampling strategy to ensure a representative sample of Grade 10 teachers. I served as the primary tool for data collection while conducting face-to-face semi-structured interviews. Data were analysed thematically to identify recurring themes and patterns that shed light on the complexities of assessment practices in the classroom. Findings from the thematic analysis of the data indicated that teachers at the Johannesburg-based high school recognise the value and potential benefits of differentiated assessment. The findings indicate that although the teachers recognise the value of differentiated assessment, they face significant structural challenges that hinder the practical implementation of differentiated assessment in their Grade 10 classrooms. The barriers faced by the teachers at the Johannesburg-based high school primarily stem from longstanding habits, curriculum pressures, and a reliance on uniform testing methods to meet departmental requirements. Such factors limit the flexibility needed to adapt assessment methods to meet the diverse needs of Grade 10 learners. Although teachers are faced with structural challenges, the study found that with appropriate support and adequate professional development, teachers at the Johannesburg-based high school were willing and capable of adopting more flexible and inclusive assessment strategies. For differentiated assessment to become a reality in Grade 10 classrooms, it is recommended that the Department of Education reduce rigid assessment mandates and adopt a more learner-centred assessment policy framework. Teachers, supported by professional development and systemic backing, would need to shift towards context-sensitive assessments that better cater to the diverse abilities, strengths, and experiences of Grade 10 learners. By empowering teachers through targeted professional development training and advocating for policy reforms, educational stakeholders can cultivate a more inclusive and responsive assessment culture that enhances learners’ potential. Incorporating differentiated assessment practices into Grade 10 South African classrooms would assist in ensuring that every learner, regardless of their unique strengths or challenges, is provided with the opportunity to demonstrate their learning in ways that are meaningful and reflective of their unique abilities. Key words: Differentiated assessment, one-size-fits-all assessment, South Africa, Grade 10, assessment practices.
