First, we trace the history of second language acquisition (SLA) from early stages in the mid-twentieth century to today. We next consider the status of the field in today's research world with a particular focus on all aspects of methodology and, finally, we take a look at the future and discuss issues related to scientific rigor in light of Open…

We explored how L2 learners of Arabic make use of video-based captions to learn vocabulary. Thirteen students watched a four-minute captioned video twice on a computer equipped with eye-tracking technology. The study included 19 novel words, 2 familiar words with novel meanings, and 2 words with familiar morphological roots (23 total). In this…

The focus in this article is on research in language centers. Four center directors provide examples of the place of research in language centers and focus on how teachers and researchers work together to facilitate large action research projects. The first section describes a survey of instructors in U.S.-based intensive English programs (IEPs).…

The Center for Language Teaching Advancement (CeLTA) at Michigan State University (MSU) was awarded a U.S. federally funded two-year grant in 2014 to investigate the status of proficiency, and the promotion of proficiency, in foreign language programs. The grant was awarded to Paula Winke and Susan Gass, as principal investigators. The purpose of…

This study represents program-level action research. A U.S. university Spanish language program had a goal for students to reach the ACTFL (2012) Intermediate Mid level after 2 years. An empirical question that resulted after regular end-of-year testing was whether the students were doing their best on assessments. To investigate this, 253…

Captions provide a useful aid to language learners for comprehending videos and learning new vocabulary, aligning with theories of multimedia learning. Multimedia learning predicts that a learner's working memory (WM) influences the usefulness of captions. In this study, we present two eye-tracking experiments investigating the role of WM in…

This paper argues for the replication of two studies, both of which consider feedback and working memory. In the first part of this paper, we discuss the role of interaction-based research and working memory research in second language acquisition research. We then describe two studies that have unified these two areas in recent published articles…

Grammaticality judgment tests (GJTs) have been used to elicit data reflecting second language (L2) speakers' knowledge of L2 grammar. However, the exact constructs measured by GJTs, whether primarily implicit or explicit knowledge, are disputed and have been argued to differ depending on test-related variables (i.e., time pressure and item…

This article constitutes the first empirical assessment of methodological quality in second language acquisition (SLA). We surveyed a corpus of 174 studies (N = 7,951) within the tradition of research on second-language interaction, one of the longest and most influential traditions of inquiry in SLA. Each report was coded for methodological…

This study investigates caption-reading behavior by foreign language (L2) learners and, through eye-tracking methodology, explores the extent to which the relationship between the native and target language affects that behavior. Second-year (4th semester) English-speaking learners of Arabic, Chinese, Russian, and Spanish watched 2 videos…

This study investigates whether raters' knowledge of test takers' first language (L1) affects how the raters orient themselves to the task of rating oral speech. The authors qualitatively investigated the effects of accent familiarity on raters' score assignment processes. Twenty-six trained raters with a second language of Mandarin Chinese,…

Second language acquisition (SLA) as a discipline has not had a long history and, as any new discipline, has seen growing pains over the years. This research timeline traces the development of the increased and more sophisticated use of statistics in SLA research and the increasing demands for rigor in their use. Use of statistical procedures has…

This study investigated whether raters' second language (L2) background and the first language (L1) of test takers taking the TOEFL iBT® Speaking test were related through scoring. After an initial 4-hour training period, a group of 107 raters (mostly of learners of Chinese, Korean, and Spanish), listened to a selection of 432 speech samples that…

This study investigated the effects of captioning during video-based listening activities. Second- and fourth-year learners of Arabic, Chinese, Spanish, and Russian watched three short videos with and without captioning in randomized order. Spanish learners had two additional groups: one watched the videos twice with no captioning, and another…

The five papers in this issue cover a range of perspectives on the acquisition and use of the Spanish copulas "ser" and "estar" in a variety of contexts, including language contact, bilingual language acquisition, and classroom second language learning. The fact that these papers cite work in this area as far back as the early part of the 20th…
