Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs. This forms a multidimensional regression discontinuity design (RDD) to analyze the effect of the educational treatment where there are two running variables…

Multilevel models (MLMs) are flexible in that they can be employed to obtain item and person parameters, test for differential item functioning (DIF) and capture both local item and person dependence. Papers on the MLM analysis of item response data have focused mostly on theoretical issues where applications have been add-ons to simulation…

This study explores the effects of various motivational variables operating within 44 English classes on 1-year-long gains in the English reading proficiency of 1,149 Japanese university students. The study adds new knowledge to the recent outcomes of second language (L2) motivational studies in 3 major ways. First, the explanatory variables…

Do undergraduates whose native language is not English have writing deficiencies leading to academic struggles? The present study showed that the answer to this question was "no" at an American West Coast public university. This university's nonresident undergraduates on average earned B- to B+ in their colleges' English…

Literature shows that attendance is an important bidirectional link in engaging students in learning. However, metacognitive awareness eludes many first-year students--particularly the disadvantaged, including those with low admission scores, English as a second language or coming from low socio-economic status (SES), migrant, or first-in-family…

This study examined the influence of prompt characteristics on the averages of all scores given to test taker responses on the TOEFL iBT[TM] integrated Read-Listen-Write (RLW) writing tasks for multiple administrations from 2005 to 2009. In the context of TOEFL iBT RLW tasks, the prompt consists of a reading passage and a lecture. To understand…

Applied linguists have identified three components of second language (L2) performance: complexity, accuracy, and fluency (CAF) to measure L2 development. Many studies researching CAF found trade-off effects (in which a higher performance in one component corresponds to lower performance in another) during tasks, often in online oral language…

Are international undergraduates struggling academically, and are their struggles due to weaknesses in English as a second language? The present study showed that 1) at most 10% of these students in three cohorts (ranging in size from N = 322 to N = 695) at an American west coast public university struggled (quarterly grade point averages below C)…

Imagery training has been shown to improve reading comprehension. Recent research has also shown that the quality of visual mental imagery used is important for reading comprehension. A review of literature shows that there has been relatively little detailed research on the quality of imagery used by learners, especially in the case of students…

This paper provides a discussion of the results of a cross-sectional examination of linguistic variables that are predicted to influence L2 reading fluency. This study is part of a larger, longitudinal mixed-methods study into reading fluency development using online Timed Reading (TR) with participants from a mid-to-high level private university…
