Concept cartoons as a formative assessment instrument in physics – a case study

Studies have shown that the practice of formative assessment is a challenge for many teachers in South Africa. Teachers are either entrenched in their old habits and methods of assessment, or they have not been adequately trained and supported to apply formative assessment in the instructional process. The aim of this research was to explore Physical Sciences teachers’ perceptions of formative assessment and the usefulness of Concept Cartoons as a formative assessment instrument to assist teachers in their practice of formative assessment. The perceptions of eight Grade 11 Physical Sciences teachers on formative assessment were sought before and after an intervention. During the intervention, the teachers were trained to use Concept Cartoons as a formative assessment instrument. The teachers’ perceptions were also sought after an implementation phase where they implemented Concept Cartoons as a formative assessment instrument in their own classrooms. The teachers were purposefully selected from six schools in the Port Elizabeth area. A qualitative case study approach, informed by a constructivist perspective, was applied in this study. Data were collected through open-ended questionnaires, semi-structured interviews, and the participants’ post-implementation written reflections. These data were analysed and presented in both narrative and tabular formats, supported by verbatim quotes from the participants. The conclusion that can be drawn from this study is that the use of Concept Cartoons as a formative assessment instrument had a substantially positive influence on the Physical Sciences teachers’ understanding and practice of formative assessment. The data also suggest that Concept Cartoons supported both learner- and teacher learning, thus functioning as an Educative Curriculum Material (ECM). Another finding in this study was that a relatively short intervention (i.e. a workshop) could make a difference in teachers’ learning and professional development. Support, however, is needed, particularly in the form of teaching resources or materials, so as to ensure the translation of knowledge into practice. Though the findings are presented within the context of the six sampled schools, and focussed on Grade 11, further research may determine these findings to be informative for other institutions within similar settings
