Do emotions and prior performance facilitate the use of the learner-generated drawing strategy? Effects of enjoyment,anxiety, and intramathematical performance on the use of the drawing strategy and modelling performance

The use of self-generated drawings has been found to be a powerful strategy for problem solving. However, many students do not engage in drawing activities. In this study, we investigated the effects of the enjoyment of the drawing strategy, anxiety about the drawing strategy, and prior intramathematical performance on the use of the drawing strategy and modelling performance. We explored the role of the drawing strategy as a mediator between emotions and modelling and whether intramathematical performance moderated the effects of emotions (N = 220, mean age 14.5 years). Enjoyment and anxiety with respect to generating drawings and intramathematical performance predicted the use of the drawing strategy. Enjoyment positively affected modelling performance indirectly via the use of the drawing strategy. Anxiety negatively affected modelling performance via the use of the drawing strategy for students with lower intramathematical performance. Our findings demonstrate that experiencing activating emotions (i.e., enjoyment and anxiety) with respect to strategies and prior intramathematical performance are important for strategy use and modelling performance. Implications for the theory of self-generated drawing and the control-value theory of achievement emotions and practical implications for training and supporting the drawing strategy are discussed.     

Signs,symbols and schemas: understanding meaning in a child’s drawings

This paper examines the schematic underpinnings in the drawings of a four-year-old girl, Thea. The paper reviews literature on graphic representations, signs and meaning-making before discussing schematic form in children’s drawings, the theoretical background for the study. The paper discusses ethical issues and methodological approaches to the study where data include drawings made at home and school, Thea’s recorded talk about drawings, and video recordings of her drawing sessions over a four-month period. These were coded manually and using NVivo to identify schemas. The paper discusses examples of Thea’s exploration of enclosure and trajectory schematic form, which are represented by rich content derived from her experiences and imagination. The paper concludes that Thea’s drawings included many schematic signifiers with clear evidence of complex thinking around enclosures and of vertical and horizontal trajectories. The paper evidences the importance of listening to children’s talk as they draw in order to understand more fully, the meanings they are making. Through signs, symbols and personal narratives, Thea used drawing as a meaningful semiotic space where her persistent schematic concerns were manifest.
