This research investigates students' achievements in algebraic thinking using Demetriou's test across 7th (approximately 12-13 years old), 8th (approximately 13-14 years old), and 9th (approximately…

Adolescence is a developmental period when youth are increasingly likely to turn to their peers for support, and it is also a time of increased salience and development of ethnic-racial identity (ERI).

With China's rapidly developing economy and increasing urbanization, many adults from rural areas migrate to urban areas for better paid jobs.

The SELF Foundation engaged 287 students at Key, Revere, and Welch middle schools in afterschool tutorials and enrichment activities to support their academic, social, and emotional development. Program impact was measured using reading and math performance, attendance, and disciplinary actions of SELF Foundation students compared to…

In this article we present a new method for estimating children's total vocabulary size based on a language corpus in German. We drew a virtual sample of different lexicon sizes from a corpus and let the virtual sample "take" a vocabulary test by comparing whether the items were included in the virtual lexicons or not. This enabled us to…
