The present quasi-experimental study investigated the comparative effects of metalinguistic clue (MC) and metalinguistic explanation (ME) on the accurate use of Japanese transaction expressions. The study recruited 25 learners in a second-semester Japanese course (i.e. non-introduced group) and 17 students in a fourth-semester course (i.e.…

Cognitive psychology research has shown that interleaving, wherein learners practice multiple skills or concepts at once, facilitates learning more than does blocking, wherein learners practice only one skill or concept at a time. Despite the advantage of interleaving over blocking observed across a number of domains, limited attention has been…

This study examined the effectiveness of explicit instruction and feedback, focusing on degrees of prior knowledge of the personal "a" in intermediate level second language (L2) Spanish. On the pretest, participants (n = 58) completed grammaticality judgment and picture description tasks, which found that learners had different degrees…

Learning the writing skill is a challenging task for second or foreign language learners. This difficulty stems from the fact that students required multiple skills and knowledge while writing. They need, for example, enough vocabulary inventory, grammar knowledge, and other discourse strategies to organize the text. Students are also in need for…

The present study investigates the effects of extensive reading on developing the language knowledge and reading abilities of high school learners of English as a foreign language (EFL) over the course of one school year. Participants were divided into control (n = 205) and experimental groups (n = 200), with the former receiving regular grammar…

This study examines the effects of the timing of explicit instruction (EI) on grammatical accuracy. A total of 123 learners were divided into two groups: those with some productive knowledge of past-counterfactual conditionals (+Prior Knowledge) and those without such knowledge (-Prior Knowledge). Each group was divided into four conditions. Two…

This study examines the effects of an online learning environment on preservice teachers' pedagogical content knowledge (PCK), content knowledge (CK) (related to French in primary teacher education), and pedagogical knowledge (PK) in a quasi-experimental design. More specifically, the following research question is addressed: Is a systematically…

This study extends the evidence for implicit second language (L2) learning, which comes largely from (semi-)artificial language research, to German. Upper-intermediate L2 German learners were flooded with spoken exemplars of a difficult morphological structure, namely strong, vowel-changing verbs. Toward the end of exposure, the mandatory vowel…

The field of Instructed Second Language Acquisition (ISLA) has expressed interest in pursuing a research agenda that expands the current heritage language (HL) strand of research to investigate how this heterogeneous population re-learns their family language, and how this experience differs from that of second language (L2) learners. This…

This dissertation tests a grammatical structure, differential object marking (DOM), which is particularly difficult for L2 learners to acquire. DOM is a phenomenon in which some direct objects are morphologically marked to distinguish them from subjects (Comrie, 1979). In Spanish, animate and specific direct objects are marked with the preposition…

Educators are being encouraged to implement new instructional designs in an era where new standards, which promote student-centered learning, are being utilized and all students are expected to be successful on standardized tests. Consequently, there is a need for further research on the effectiveness of student-centered instruction. For that…
