Developmental Trajectories of Acculturation: Links With Family Functioning and Mental Health in Recent‐Immigrant Hispanic Adolescents

The present study was designed to examine acculturative changes, and their effects on mental health and family functioning, in recent‐immigrant Hispanic adolescents. A sample of 302 Hispanic adolescents was assessed five times over a 2½‐year period. Participants completed measures of Hispanic and U.S. practices, collectivist and individualist values, and ethnic and U.S. identity at each time point. Baseline and Time 5 levels of mental health and family functioning were also assessed. Latent class growth analyses produced two‐class solutions for practices, values, and identifications. Adolescents who increased over time in practices and values reported the most adaptive mental health and family functioning. Adolescents who did not change in any acculturation domain reported the least favorable mental health and family functioning.     

Longitudinal Trajectories of Family Functioning Among Recent Immigrant Adolescents and Parents: Links With Adolescent and Parent Cultural Stress,Emotional Well-Being,and Behavioral Health

This study examined longitudinal effects of adolescent and parent cultural stress on adolescent and parent emotional well-being and health behaviors via trajectories of adolescent and parent family functioning. Recent immigrant Latino adolescents (M_age = 14.51) and parents (M_age = 41.09; N = 302) completed measures of these constructs. Latent growth modeling indicated that adolescent and parent family functioning remained stable over time. Early levels of family functioning predicted adolescent and parent outcomes. Baseline adolescent cultural stress predicted lower positive adolescent and parent family functioning. Latent class growth analyses produced a two-class solution for family functioning. Adolescents and parents in the low family functioning class reported low family functioning over time. Adolescents and parents in the high family functioning class experienced increases in family functioning.     

A design-based research case study documenting a constructivist ID process and instructional solution for a cross-cultural workforce

As the need for instructing a globalized workforce increases, instructional designers must embrace the constraints and the opportunities these projects provide in order to move the field of cross-cultural instructional design (ID) forward. Cross-cultural projects offer multiple avenues for growth in ID practice, overcoming cultural barriers, and a venue to apply and test contemporary models, methodologies, and theories in ID. This design-based research case study employed a rapid prototyping methodology and the constructivist ID model, Layers of Negotiation, to collect critical cultural information for the design of this cross-cultural instruction. Instructional strategies deemed effective for instructing an unskilled workforce in Dubai, United Arab Emirates, included job aids, situated learning and apprenticeship principles consisting of modeling, coaching and scaffolding. Use of the constructivist ID model and instructional solution for a cross-cultural workforce for The Dubai Mall are presented. Evaluation results indicate the success of the instructional strategies varied dependent upon worker culture, and the sequential nature of the instructional strategies.     

A new look in representations for mathematics and science learning

Representations such as formal notations and diagrams routinely figure in students' learning of mathematics and science. However, in light of the extensive research on students' misunderstanding in these subject matters, it is reasonable to ask whether other kinds of representations might help students to reach better understandings. Indeed, a number of educators have developed innovative representations, typically on computers, that supposedly foster understanding through suggestive visual analogies and microworlds to manipulate. Evaluative research on these new look representations as we call them suggests that they indeed can help students to understand.In this review, we focus on exactlyhow these representations aid understanding. We propose that they do so by facilitating the learner's construction of explanations, justifications, predictions, and the like. These constructions require search in problem spaces, in the sense of Newell and Simon (1972). The representations in question reduce the cognitive load of such searches, clarify the structure of the problem spaces that need to be searched, and make certain moves in the problem spaces more immediate. We invoke Gentner's (1983) theory of structure mapping to explain how these advantages are attained. We also examine several characteristic pitfalls of representations in this style.
