Immersion has been an acclaimed approach for second-language acquisition, but is not available to most students. The idea of this study was to create a mobile immersion environment on a smartphone using a mobile instant messenger, WhatsApp™. Forty-five Form-1 (7th grade) students divided into the Mobile Group and Control Group participated in a…

The current study models reader, item, and word contributions to the lexical representations of 39 morphologically complex words for 172 middle school students using a crossed random-effects item response model with multiple outcomes. We report 3 findings. First, results suggest that lexical representations can be characterized by separate but…

This study aims to investigate the techniques of teaching new lexis which are adopted by non-native teachers of English language. It also aims to investigate the strategies of learning new lexis which are adopted by learners in relation to their level. The work is based on two hypotheses: It is hypothesized that there is a relationship between the…

Twenty-four studies were included in this systematic review of vocabulary research literature. The review corroborates the findings of past studies that several strategies have emerged that increase students' vocabulary knowledge. Findings further reinforce the National Reading Panel's recommendations regarding the context and magnitude of studies…

The purpose of this study was to determine the reading achievement effects of a school-year-long program of sustained silent reading in a middle school. Students' scores on the Stanford Achievement Test, Ninth Edition across three years (2006, 2007, and 2008) were analyzed to test eleven null hypotheses. A 3 x 3 repeated measures factorial ANOVA…

In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n = 85)…

Studies on using still images and dynamic videos in multimedia annotations produced inconclusive results. A further examination, however, showed that the principle of using videos to explain complex concepts was not observed in the previous studies. This study was intended to investigate whether videos, compared with pictures, better assist…
