The study sought to determine the relationship between problem-solving skills and measure of working memory and attention span of science students of low ability level. The study adopted correlational survey research design. The population for the study comprised all Secondary School I (SSI) that offered physics, chemistry and biology as school…

In this study, we test an information-processing model (IPM) of problem solving in science education, namely the working memory overload model, by applying catastrophe theory. Changes in students' achievement were modeled as discontinuities within a cusp catastrophe model, where working memory capacity was implemented as asymmetry and the degree…
