Teacher judgement accuracy of technical abilities in primary education

Accurate teacher judgements can enhance pupils' learning about science and technology. This study explored primary school teachers' judgements about their pupils' ability to reconstruct an electrical and a mechanical system. The judgement accuracy of most teachers was poor, gender-biased, and underestimation was more common than overestimation. The teachers’ gender or self-efficacy beliefs do not seem to affect their judgement accuracy, whereas greater technical knowledge and teaching experience might be beneficial. The teachers’ judgements were primarily based on their estimation of pupils’ cognitive abilities and learning behaviour, which both had less bearing on pupils’ performance than the teachers had expected. Diagnostic tasks for technical abilities, like the ones used in this study, can be used by primary school teachers working with children aged nine and above to calibrate their judgement accuracy and adapt their teaching to their pupils’ varying levels of prior knowledge. Pupils’ performance on these non-verbal tasks can reveal unexpected abilities.
