This article reports on two studies, testing how three different types of input (skewed first, skewed random and balanced) affect second language (L2) learning of English present counterfactual (IF-Is) and past counterfactual (IF-IIs) conditionals, two constructions differing in complexity. The experiment included a proficiency test, a pretest, a…

This study investigates the effects of input-based and output-based instructions on the acquisition of second language (L2) request modifiers. Four intact classes were randomly assigned to textual enhancement (TE), input flooding (IF), output-based instruction (OI), and control (CO) groups. The TE group watched some captioned videos on requests…

Collaborative writing (CW) has been proven advantageous to enhance the second and foreign language skills of university students. However, little research to date has explored whether CW practices are fruitful for secondary school learners in foreign language (FL) contexts, a population characterized by low language proficiency levels, and few…

The present study employed a mixed methods quasi-experimental design to investigate the effectiveness of applying motivational strategies and mental imagery (i.e. visionary techniques) to facilitate second language (L2) vocabulary learning. Four treatment sessions were integrated into a six-week language course offered to 150 intermediate students…

This study examined the optimal learning schedule for second language vocabulary within an authentic classroom setting in Hong Kong. Following a pretest, treatment, delayed posttest design, fifty-two primary school students (Cantonese first language) studied 20 English adjectives over two learning episodes under spaced-short (1-day interval) or…

Recently, second language (L2) instruction has benefitted from the development of instructional technology such as synchronous computer-mediated communication (SCMC). The present study was conducted to investigate learner perception of the effectiveness of SCMC interactions for L2 learning and building intercultural competence. Students (n = 55)…

This study investigates the effect of instruction on the acquisition of pragmatic routines used in academic discussion, specifically expressions of agreement, disagreement, and clarification. Thirty-seven learners, including an experimental group of 26 students and a control group of 11 students, participated in the study. Five intact classes…

The present study evaluates the relative effectiveness of two types of input-based instruction, structured input instruction (a structured input task only) and structured input instruction with feedback (the structured input task + reactive explicit feedback) for teaching English polite requestive forms, involving 45 Japanese learners of English.…

Experimental second language acquisition research typically investigates the effectiveness of instruction in terms of overall group gains. A particular instructional method may not, however, benefit all learners uniformly. This study, conducted in a New Zealand secondary school, establishes whether there is any relationship between the…
