How to Measure and Explain Achievement Change in Large-Scale Assessments: A Rejoinder

In this rejoinder, we discuss substantive and methodological validity issues of large-scale assessments of trends in student achievement, commenting on the discussion paper by Van den Heuvel-Panhuizen, Robitzsch, Treffers, and Köller (2009). We focus on methodological challenges in deciding what to measure, how to measure it, and how to foster stability. Next, we discuss what to do with trends that are found. Finally, we reflect on how the research findings were received.     

Diamonds in the Rough: Bridging Gaps in Supports for At-Risk Immigrant and Refugee Youth

Immigrant youth come to Canada with enormous potential to make a significant, positive contribution to the future of their adopted country. In many cases, this potential is realised; in others, it is not. The ease with which immigrant youth and their families integrate into Canadian society has a strong impact on their futures; those who become marginalised during this process risk becoming alienated or involved with the criminal justice system. Interviews were conducted with 12 stakeholders (including representatives from social service agencies, community groups and the criminal justice and forensic mental health systems) who frequently come into contact with immigrant and refugee youth involved in criminal and/or gang activity. Based on the family, individual, peer, school and community risk and protective factors reported to have an influence on immigrant and refugee youth, recommendations are made for bridging gaps in programming and policy initiatives to support at-risk youth.     

Differential susceptibility experiments: going beyond correlational evidence: comment on beyond mental health, differential susceptibility articles

Reviewing the studies on differential susceptibility presented in this section, we argue that the time is ripe to go beyond correlational designs to differential susceptibility experiments. In such experiments, randomization prevents hidden moderator effects on the environment and guarantees the independence of moderator and outcome, while the environment is manipulated and assessed in standard ways. Correlational studies generate a priori expectations about crucial moderators (e.g., temperament, biological sensitivity, and genetics). We discuss the differential susceptibility experiments available up until now and conclude that these experiments are feasible and contribute in unique ways to our conceptions of differential susceptibility.     

Bimodal bilinguals co-activate both languages during spoken comprehension

Bilinguals have been shown to activate their two languages in parallel, and this process can often be attributed to overlap in input between the two languages. The present study examines whether two languages that do not overlap in input structure, and that have distinct phonological systems, such as American Sign Language (ASL) and English, are also activated in parallel. Hearing ASL-English bimodal bilinguals' and English monolinguals' eye-movements were recorded during a visual world paradigm, in which participants were instructed, in English, to select objects from a display. In critical trials, the target item appeared with a competing item that overlapped with the target in ASL phonology. Bimodal bilinguals looked more at competing item than at phonologically unrelated items and looked more at competing items relative to monolinguals, indicating activation of the sign-language during spoken English comprehension. The findings suggest that language co-activation is not modality specific, and provide insight into the mechanisms that may underlie cross-modal language co-activation in bimodal bilinguals, including the role that top-down and lateral connections between levels of processing may play in language comprehension.
