Revisiting the integration hypothesis again: High heterogeneity complicates the interpretation of cross-sectional evidence

A recent meta-analytical paper (Bierwiaczonek & Kunst, 2021) sparked a controversy by demonstrating that cross-sectional associations between acculturation preferences and adaptation are weak and heterogenous, and approach zero when assessed over time. Some responses criticized the paper by arguing that small but robust effects can make a real-life difference if applied to millions of migrants. In this paper, we present additional analyses to illustrate how the heterogeneity of correlational integration effects complicates and potentially undermines this notion. We estimate that true effects of integration and heritage culture orientation are negative almost 30 % of the time, and only true effects of mainstream culture orientation seem to be relatively homogenous. We conclude that the combination of a weak effect with high heterogeneity makes integration effects largely unpredictable, meaning that for some migrant groups, adopting the integration strategy will be associated with positive outcomes, and for others with negative outcomes, with no evidence that any of those outcomes are caused by integration.     

Why do people play games? A meta-analysis

During the last decade games have arguably become the largest form of leisure information systems (IS). However, today games are also increasingly being employed for a variety of instrumental purposes. Although games have garnered a substantial amount of research attention during the last decade, research literature is scattered and there is still a lack of a clear and reliable understanding of why games are being used, and how they are placed in the established utilitarian-hedonic continuum of information systems. To address this gap, we conducted a meta-analysis of the quantitative body of literature that has examined the reasons for using games (48 studies). Additionally, we compared the findings across games that are intended for either leisure or instrumental use. Even though games are generally regarded as a pinnacle form of hedonically-oriented ISs, our results show that enjoyment and usefulness are equally important determinants for using them (though their definitive role varies between game types). Therefore, it can be posited that games are multi-purpose ISs which nevertheless rely on hedonic factors, even in the pursuit of instrumental outcomes. The present study contributes to and advances our theoretical and empirical understanding of multi-purpose ISs and the ways in which they are used.     

Comparing response rates in e-mail and paper surveys: A meta-analysis

This meta-analysis examined 35 study results within last 10 years that directly compared the response rates of e-mail versus mail surveys. Individual studies reported inconsistent findings concerning the response rate difference between e-mail and mail surveys, but e-mail surveys generally have lower response rate (about 20% lower on the average) than mail surveys. Two study features (population type and follow-up reminders) could account for some variation in the e-mail and mail survey response rate differences across the studies. For the studies involving college populations, the response rate difference between e-mail and mail surveys was much smaller, or even negligible, suggesting that e-mail survey is reasonably comparable with mail survey for college populations. The finding about follow-up reminder as a statistically significant study feature turns out to be somewhat an anomaly. Other study features (i.e., article type, random assignment of survey respondents into e-mail and mail survey modes, and use of incentives) did not prove to be statistically useful in accounting for the variation of response rate differences between mail and e-mail surveys. The findings here suggest that, in this age of internet technology, mail survey is still superior to e-mail survey in terms of obtaining higher response rate.     

A meta-analysis of comparative studies on Chinese and US students’ mathematics performance: Implications for mathematics education reform and research

US and China are reforming mathematics teaching by shifting from students’ attainment of facts and procedures toward development of competencies in reasoning, communication, connections, and problem solving, and application of these in real life contexts. Differences in students’ overall performance, curricula, and teachers’ knowledge and instruction between US and Eastern Asian countries are often used to support US reform with two obvious limitations. First, their performance has not been delineated into specific areas which raise questions about whether overall higher Asian mathematics performance over US is also evident in the specific US reform competencies. Second, Asians are often used as an indiscriminate group with inattention to different schooling and non-schooling factors between countries that might contribute differently to performances. This meta-analysis examines US and Chinese student mathematics performance studies and identifies the strengths and weaknesses in overall and specific competencies. It raises questions about theoretical assumptions, discusses limitations of research designs, and proposes research that may lead to a critical understanding of the quality of mathematics learning.

A meta-analysis of the effects of Montessori education on five fields of development and learning in preschool and school-age children

This meta-analysis examines the effects of Montessori Education (ME) on five dimensions of development and learning in preschool and school-age children. It includes data from 33 experimental or quasi-experimental studies comparing ME with other pedagogical approaches (268 effect sizes; n = 21,67). These studies were conducted in North-America, Asia and Europe, and published between 1991 and 2021. Effect size estimated using Hedges’ unbiased g, and a 3-level multilevel meta-analytic approach applied due to the dependency among the effect sizes obtained from the same study. Results showed that ME’s effects on development and learning are positive and vary from moderate to high, depending on the dimension considered: cognitive abilities (g = 0.17), social skills (g = 0.22), creativity (g = 0.25), motor skills (g = 0.27), and academic achievement (g = 1.10). Analyses of different moderators did not reveal differences by school level, type of publication and continent.     

Meta-analysis of faculty's teaching effectiveness: Student evaluation of teaching ratings and student learning are not related

Student evaluation of teaching (SET) ratings are used to evaluate faculty's teaching effectiveness based on a widespread belief that students learn more from highly rated professors. The key evidence cited in support of this belief are meta-analyses of multisection studies showing small-to-moderate correlations between SET ratings and student achievement (e.g., Cohen, 1980, Cohen, 1981; Feldman, 1989). We re-analyzed previously published meta-analyses of the multisection studies and found that their findings were an artifact of small sample sized studies and publication bias. Whereas the small sample sized studies showed large and moderate correlation, the large sample sized studies showed no or only minimal correlation between SET ratings and learning. Our up-to-date meta-analysis of all multisection studies revealed no significant correlations between the SET ratings and learning. These findings suggest that institutions focused on student learning and career success may want to abandon SET ratings as a measure of faculty's teaching effectiveness.     

Identifying effective interventions for promoting parent engagement and family reunification for children in out-of-home care: A series of meta-analyses

BackgroundAn important obstacle for family reunification following child placement in residential care and other temporary out-of-home care services is the lack of engagement among parents.ObjectiveThe aim of this meta-analysis is to identify the most effective interventions to promote parental engagement and family reunification.Method and participantsEight studies, for a total of 2996 families, were used to conduct two series of meta-analyses. Each study examined the effectiveness of a goal-oriented parental engagement intervention, relative to a control group made up of parents who received standard services. Six moderators were analyzed: type of clinical modality, number of clinical strategies, sources of motivation for intervention, focus on the child care staff-parent relationship, child care staff training, and strategies to promote access to intervention.ResultsResults indicate that parents exposed to goal-oriented engagement interventions showed greater engagement (effect size d = 0.71, CI: 0.35–1.07, p < 0.001) and likelihood of reunification (effect size OR = 2.49, CI: 1.22–5.10, p < 0.05) than parents who received standard services. In particular, moderator analysis showed that parents who specifically participated in a family-focused intervention showed the highest engagement in comparison to parents involved in other types of interventions or who received standard services (effect size d = 1.08, CI: 0.58–1.59, p < 0.001). No moderators significantly explained heterogeneity of studies on family reunification.ConclusionOverall, the results underline the effectiveness of family-focused interventions to promote parental engagement. Nevertheless, greater knowledge on the mechanisms by which interventions can increase parents’ engagement and family reunification is still needed.
