The Relation between Short-Term Memory and Vocabulary Skills in Greek Children with Cochlear Implants: The Role of Hearing Experience

Peer reviewed

Direct link

Talli, Ioanna; Tsalighopoulos, Miltiadis; Okalidou, Areti – First Language, 2018

Weak performance in short-term memory (STM) in children with cochlear implants (CI) may have an impact on vocabulary development. Vocabulary, phonological STM (non-word repetition), phonological/verbal STM (digit span) and rapid naming measures were administered to 15 Greek-speaking children with CI (ages 4;6-8;6) and to chronological age (CA) and…

The Effects of "Green Chemistry" on Secondary School Students' Understanding and Motivation

Peer reviewed

Direct link

Karpudewan, Mageswary; Roth, Wolff-Michael; Ismail, Zurida – Asia-Pacific Education Researcher, 2015

As an initial effort to reorient the current Malaysian chemistry curriculum, "green chemistry" was developed. In this study for the purpose of investigating the effectiveness of the green chemistry curriculum on secondary school students' understanding of chemistry concepts a quasi-experimental design was used. One-group pretest posttest…
