When working within a meaningful context quite young students are capable of working with sophisticated data. Year 3 students investigate thermal insulation and the transfer of heat in a STEM inquiry, developing skills in measuring temperature by conducting a statistical investigation, and using a stylised graph to interpret their data.

In a series of 3 experiments, the authors investigated the influence of symmetry of variables on children's and adults' data interpretation. They hypothesized that symmetrical (i.e., present/present) variables would support correct interpretations more than asymmetrical (i.e., present/absent) variables. Participants were asked to judge covariation…

The present study used data from the Trends in International Mathematics and Science Study (TIMSS) 2003 to look at the trend in instructional strategies in science teaching and its effect on the science achievement. Based on the analysis, the strategies used by most science teachers were demonstration, practical work and the lecture method. Among…
