The effects of part-task and whole-task instructional approaches on acquisition and transfer of a complex cognitive skill

This study was designed to investigate the effects of two instructional approaches (whole-task versus part-task) and two levels of learner prior knowledge (lower versus higher) on learner acquisition and transfer of a complex cognitive skill. Participants were 51 undergraduate pre-service teachers. In the part-task condition, a complex skill (preparing a grade book using Excel) was decomposed into a series of smaller tasks, each of which was demonstrated and practiced separately. In the whole-task condition, which was based on the 4C/ID-model (van Merriënboer 1997), learners were exposed to the entire complex skill from the beginning of the instruction and were required to practice performing a series of whole tasks throughout the unit. Results indicated that the whole-task group performed significantly better than the part-task group on a skill acquisition test and a transfer test. Possible reasons for these findings and suggestions for future research are discussed.     

＂I don＇t see color,I only see children!＂： A study of teachers＇ color-blindness for Asian students/family

The purpose of this study is to explore USA educators＇ resistance toward cultural awareness for Korean students and families in the New York metropolitan area. The authors aim to challenge teachers＇ color-blindness that is widely spread among USA educators. Guided by critical race theory, the authors show that the perceived fairness of color-blindness could cause struggles for Korean parents and students in American schools. The authors posit USA teachers need to thoroughly understand that if a teacher does not see color, then s/he does not really see children. This study, hopefully, will help educators recognize the necessity of understanding diverse ethnic parents＇ perspectives and needs. Also, this study will provide an opportunity for educators to rethink assumptions that are embedded in color-blindness, and advance muiticultural education that is more culturally relevant and responsive for different ethnic/racial groups＇ needs.     

Decolonizing educational/curriculum studies in East Asia: problematizing shadow education in South Korea

This essay review critically engages Young Chun Kim's book, Shadow Education and the Curriculum and Culture of Schooling in South Korea, by responding to two central questions at its heart: What does decolonization of educational research mean and what does it look like? In what way can cultural studies of countries with histories of colonized educational systems challenge the inertia to recapitulate colonized historical consciousness? Kim provides theoretical and empirical foundations for generating intellectual space that reveals the dialectical relationship between the dominant modes of discourse in educational research and aspirations of the colonized to envision their own educational culture and history.     

Does exercise have a protective effect on cognitive function under hypoxia? A systematic review with meta-analysis

ObjectiveThis study aimed to examine (1) the independent effects of hypoxia on cognitive function and (2) the effects of exercise on cognition while under hypoxia.MethodsDesign: Systematic review with meta-analysis. Data sources: PubMed, Scopus, Web of Science, PsychInfo, and SPORTDiscus were searched. Eligibility criteria for selecting studies: randomized controlled trials and nonrandomized controlled studies that investigated the effects of chronic or acute exercise on cognition under hypoxia were considered (Aim 2), as were studies investigating the effects of hypoxia on cognition (Aim 1).ResultsIn total, 18 studies met our inclusionary criteria for the systematic review, and 12 studies were meta-analyzed. Exposure to hypoxia impaired attentional ability (standardized mean difference (SMD) = –0.4), executive function (SMD = –0.18), and memory function (SMD = –0.26), but not information processing (SMD = 0.27). Aggregated results indicated that performing exercise under a hypoxia setting had a significant effect on cognitive improvement (SMD = 0.3, 95% confidence interval: 0.14 – 0.45, I² = 54%, p < 0.001). Various characteristics (e.g., age, cognitive task type, exercise type, exercise intensity, training type, and hypoxia level) moderated the effects of hypoxia and exercise on cognitive function.ConclusionExercise during exposure to hypoxia improves cognitive function. This association appears to be moderated by individual and exercise/hypoxia-related characteristics.     

Platform Competition in the Video Game Console Industry: Impacts of Software Quality and Exclusivity on Market Share

This study examines impacts of the complementary products on platform competition, in the context of video game consoles. Using 10-year panel data, the results demonstrate that high-quality software has a disproportionately significant effect on hardware demand. The high-quality exclusive software is an important factor affecting consumers’ utility, and it tends to be developed in hardware manufacturers’ vertically integrated subsidiaries. In addition, this study also identifies that high-quality multi-homing software plays a role in platform growth in a platform’s later stage.

Two-Step Approach to Partial Factorial Invariance: Selecting a Reference Variable and Identifying the Source of Noninvariance

To date, no effective empirical method has been available to identify a truly invariant reference variable (RV) in testing measurement invariance under a multiple-group confirmatory factor analysis. This study proposes a method that, in selecting an RV, uses the smallest modification index (min-mod). The method’s performance is evaluated using 2 models: (a) a full invariance model, and (b) a partial invariance model. Results indicate that for both models the min-mod successfully identifies a truly invariant RV (Study 1). In Study 2, we use the RV found in Study 1 to further evaluate the performance of item-by-item Wald tests at locating a noninvariant variable. The results indicate that Wald tests overall performed better with an RV selected in a partial invariance model than an RV selected in a full invariance model, although in certain conditions their performances were rather similar. Implications and limitations of the study are also discussed.     

Parental involvement,children's aspirations,and achievement in new immigrant families

The authors investigated the relationships among multiple aspects of parental involvement (English proficiency, school involvement, control and monitoring of children), children's aspirations, and achievement in new immigrant families in the United States. They used data on immigrant parents and school-age children (N = 1,255) from the New Immigrant Survey to examine immigrant families from diverse backgrounds. Structural equation modeling analyses revealed that parental English proficiency and involvement in school education are related to children's academic achievement, cognitive development, and English language ability, directly as well as indirectly, through children's educational aspirations. Parental control and monitoring is not beneficial to immigrant children's cognitive development, although variations were found across different groups. They also observed intriguing findings regarding gender and racial or ethnic diversity. Based on their findings, they provide recommendations for the fostering of academic success and the design and implementation of educational programs and practices for immigrant children.     

Course-level modeling of preservice teacher learning of technology integration

We introduce an analytic approach to examine preservice teachers' technology integration learning as a process mapped against their technology-related course experience in a technology integration course. The approach assumes that (1) the preservice teachers have common course learning experience; (2) their data are collected pre- and post-course and paired; (3) the sample size is large enough to generate a structural covariance model; (4) the measurement is contextualized to the course characteristics around the types of technology tasks/tools used in the course and whether or not they were explicitly taught. The approach was applied to 368 preservice teachers' paired data to illustrate how the approach addresses the methodological issue of construct validity in TPACK measures, highlights the importance of technology integration course experience, and provides useful insights into a particular technology integration learning to its stakeholders.     

The social,economic and political contexts of adults' participation in undergraduate programmes: a state-level analysis

This study examined the extent to which socially structured factors impact adults' participation in undergraduate programmes in the USA. In a collective sense, this study started with an assumption that adults' decision to participate in educational programmes does not only rely on individual psychological and their adjacent environmental attributes, but it is also, in part, influenced by socially structured contexts surrounding them. Using the state as a unit of analysis, this study analysed the relationships between socio-demographic, economic, educational and political factors and the variation of adults' participation in the undergraduate programmes. Variables from both educational and socio-demographic factors had stronger relationships with adults' participation. Some variables that states can control through policy-related actions were meaningfully associated with adults' participation. Through this sociological understanding of adult participation in higher education, this study will supplement the lack of attention to macro-level perspectives in participation research in adult education.
