Expectancy-value motivation profiles were identified in a sample of US ninth-grade students in 2009 (n = 19,259) using latent profile analysis. Of four distinct profiles, two were high, one typical, and one low in math and in science. In each area, the two high profiles were distinguished by (1) high self-efficacy with lower utility value and (2)…

Findings are presented from a large two-phase research study exploring (a) the identification and (b) programming for mathematically gifted students with learning difficulties (MG/LDs) in Jordan. The second phase of the research, which is the focus of the current article, investigates the effects of two programs of instructional practices on the…

In this study, psychometric properties of the test of the three-mathematical minds (M3) were investigated. The M3 test was developed based on a multidimensional conception of giftedness to identify mathematically talented students. Participants included 291 middle-school students. Data analysis indicated that the M3 had a 0.73 coefficient as a…
