The effectiveness of an experimental middle school fraction intervention was evaluated. The intervention was centered on the number line and incorporated key principles from the science of learning. Sixth graders (N = 51) who struggled with fraction concepts were randomly assigned at the student level to the experimental intervention (n = 28) or…

The current study aims to improve primary stage pupils' EFL vocabulary learning and retention skills through using mnemonics. Sixty four 6th grade primary school pupils were randomly assigned into experimental and control groups. The…

Sixth-grade students studying Latin America were placed in experimental and comparison groups to test the effects of map-study repetition on long-term memory. Mean scores on place-name repetition indicated that the experimental (repetition) group out-performed the comparison group at a statistically significant level with respect to both posttest…

Two studies were conducted to explore mathematical precocity in young children. Study 1 examined mathematically gifted first and third graders' working memory development. The results showed that mathematically gifted children's working memory growth was similar to that expected of their age peers. Study 2 examined changes in mathematically gifted…
