Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

Students best learn science through a combination of science inquiry and language learning. This article presents a series of chemistry lessons on the naming of compounds. The weeklong unit focuses on patterns across compound names and chemical formulas and addresses several of the "Next Generation Science Standards" (NGSS Lead States…

A remarkable feature of the set of papers in this issue is the consistent pattern of tending to deal with non-linear situations as if they are linear that is shown by students widely differing in age and educational systems, and studying various topics within mathematics. Methodological issues about the difficulty of interpretation of student…

Context is identified as an important factor when considering the learning of informal statistical inferential reasoning, but research in this area is very limited. This small exploratory study in one grade 10 (14 year olds) classroom seeks to learn more about the role context plays in learners' inferential reasoning, where both teacher and…

This technical brief responds to an Arizona Department of Education request to study academic performance in schools receiving funding through the federal Title I compensatory education program, the section of the No Child Left Behind Act of 2001 governing resources for schools and districts serving disadvantaged populations. The brief describes…

This study examines the baseline change profiles of academic performance (math and English) trajectories during the high school transition for the students who went from middle school to high school. Using multidimensional scaling growth profile analysis, we identified a no-change group plus 4 other groups with different change profile types: 1…
