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

Background: Maturation of prefrontal circuits during adolescence contributes to the development of cognitive processes such as decision-making. Recent theories suggest that these neural changes also play a role in the shift from generalized anxiety disorder (GAD) to depression that often occurs during this developmental period. Cognitive models of…

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.…

This article presents a model of formative task-based language assessment implemented in the Chinese language program at the University of Iowa. The model was conceptualized from both empirical evidence, namely previous research done by other team members and me, and assessment theory, namely task-based learning and testing. Our formative…

This article provides renewed converging empirical evidence for the hypothesis that asking test-takers to respond to text passages with multiple-choice questions induces response processes that are strikingly different from those that respondents would draw on when reading in non-testing contexts. Moreover, the article shows that the construct of…

New information and communications technologies and research in cognitive science have led to new ways to think about and implement learning environments. Among these new approaches to instruction and new methods to support learning and performance is an interest in and emphasis on complex subject matter (e.g., complex and dynamic systems…

The present study looks at the levels of activation of different languages a trilingual language user operates in at the moment of text construction in one of these languages. Forty-eight Portuguese advanced users of English (L2) and intermediate in German (L3) were asked to perform a translation task. The subjects were divided into two subgroups:…

This article reviews previous studies of the effects of implicit and explicit corrective feedback on SLA, pointing out a number of methodological problems. It then reports on a new study of the effects of these two types of corrective feedback on the acquisition of past tense -ed. In an experimental design (two experimental groups and a control…

In the past, multitasking was a juggling act performed by busy adults, as they tried to manage jobs, chores, carpools, and PTA meetings. But recently, teens and tweens have turned into the real experts at multitasking, as their lives become chock-full of organized activities. For them, multitasking has simply become a way of life: "If I couldn't…

The major literature review by Black and Wiliam (1998a) provided strong research evidence indicating that assessment for learning can produce significant gains in students' learning. The present study applied the main aspects of assessment for learning, as highlighted in the Black and Wiliam review, in a specific area of science education, that of…

Misuse of English conjunction related to incoherent writing, according to the literature, comes from learners' first language interference, improper mechanical exercises, and misleading lists of connectors in textbooks demonstrated as if mutually interchangeable without contextual constraints. Form-focused instruction with explicit semantic,…

Utilizing a pre- and posttest research design, with an instructional intervention of good practices in notetaking, the notes taken by examinees during a computer-based listening comprehension test prior to and following the instructional intervention were examined for particular notetaking strategies. Questionnaires probed perceptions of the…
