Most researchers have studied students' academic self-concept within native language and mathematics, indicating the multidimensional nature of academic self-concept. However, there is a shortage of studies that examined the twofold multidimensional structure of verbal self-concept within the internal/external frame of reference (I/E) model of two…

This study explores the reading strategies (RSs) of bilingual and monolingual young learners in their first and second languages (L1 and L2, respectively)--either Kazakh or Russian as the L1 and L2--and English as a foreign language (L3). It also examines the influence of RSs on the learners' performance on reading comprehension tests in the three…

The internal/external (I/E) frame of reference entails high, positive association of mathematics and verbal achievements with matching academic self-concepts but negative or near-zero correlation with their nonmatching self-concepts. This study aimed to extend the traditional I/E model by contrasting the mathematics domain with two foreign…
