Growing up digital.

The Victorian Department of Education and Early Childhood Development [DEECD], Symantec, Cyber Safe Kids and Common Sense Media are currently conducting a pilot collaborative project in which 10 selected schools are trialing a digital citizenship curriculum. This digital citizenship curriculum has been aligned with local/national and international curriculum achievement standards, learning areas, competencies/capabilities. Participating schools will also trial the use of an Incident Response Tool.

Replications in Psychology Research: How Often Do They Really Occur?

Recent controversies in psychology have spurred conversations about the nature and quality of psychological research. One topic receiving substantial attention is the role of replication in psychological science. Using the complete publication history of the 100 psychology journals with the highest 5-year impact factors, the current article provides an overview of replications in psychological research since 1900. This investigation revealed that roughly 1.6% of all psychology publications used the term replication in text. A more thorough analysis of 500 randomly selected articles revealed that only 68% of articles using the term replication were actual replications, resulting in an overall replication rate of 1.07%. Contrary to previous findings in other fields, this study found that the majority of replications in psychology journals reported similar findings to their original studies (i.e., they were successful replications). However, replications were significantly less likely to be successful when there was no overlap in authorship between the original and replicating articles. Moreover, despite numerous systemic biases, the rate at which replications are being published has increased in recent decades.

Facts Are More Important Than Novelty Replication in the Education Sciences

Despite increased attention to methodological rigor in education research, the field has focused heavily on experimental design and not on the merit of replicating important results. The present study analyzed the complete publication history of the current top 100 education journals ranked by 5-year impact factor and found that only 0.13% of education articles were replications. Contrary to previous findings in medicine, but similar to psychology, the majority of education replications successfully replicated the original studies. However, replications were significantly less likely to be successful when there was no overlap in authorship between the original and replicating articles. The results emphasize the importance of third-party, direct replications in helping education research improve its ability to shape education policy and practice.

What One Hundred Years of Research Says About the Effects of Ability Grouping and Acceleration on K–12 Students’ Academic Achievement Findings of Two Second-Order Meta-Analyses

Two second-order meta-analyses synthesized approximately 100 years of research on the effects of ability grouping and acceleration on K–12 students’ academic achievement. Outcomes of 13 ability grouping meta-analyses showed that students benefited from within-class grouping (0.19 ≤ g ≤ 0.30), cross-grade subject grouping (g = 0.26), and special grouping for the gifted (g = 0.37), but did not benefit from between-class grouping (0.04 ≤ g ≤0.06); the effects did not vary for high-, medium-, and low-ability students. Three acceleration meta-analyses showed that accelerated students significantly outperformed their nonaccelerated same-age peers (g = 0.70) but did not differ significantly from nonaccelerated older peers (g = 0.09). Three other meta-analyses that aggregated outcomes across specific forms of acceleration found that acceleration appeared to have a positive, moderate, and statistically significant impact on students’ academic achievement (g = 0.42).

Replication of Special Education Research Necessary but Far Too Rare

Increased calls for rigor in special education have often revolved around the use of experimental research design. However, the replicability of research results is also a central tenet to the scientific research process. To assess the prevalence, success rate, and authorship history of replications in special education, we investigated the complete publication history of every replication published in the 36 journals categorized by ISI Web of Knowledge Journal Citation Report as special education. We found that 0.5% of all articles reported seeking to replicate a previously published finding. More than 80% of these replications reported successfully replicating previous findings. However, replications where there was at least one author overlapping with the original article (which happens about two thirds of the time) were statistically significantly more likely to find successful results.

Studying Intellectual Outliers Are There Sex Differences, and Are the Smart Getting Smarter?

By studying samples of intellectual outliers across 30 years, researchers can leverage right-tail data (i.e., samples at or above the 95th percentile on tests of ability) to uncover missing pieces to two psychological puzzles: whether there are sex differences in cognitive abilities among smart people, and whether test scores are rising (a phenomenon known as the Flynn effect) among smart people. For the first puzzle, data indicate that the high male-to-female ratio among extremely high scorers on measures of math ability has decreased dramatically, but is still likely one factor among many explaining female underrepresentation in some professions. For the second puzzle, data indicate that the right tail has risen at a similar rate as the general (or middle portion of the) distribution; it is thus likely that the entire curve is rising at a relatively constant rate, consistent with the Flynn effect, which may explain why a greater number of gifted students have been identified in recent years. However, the causes for these gains and whether they reflect real gains in intelligence continue to remain a mystery. We show how these two puzzles are linked and stress the importance of paying attention to the entire distribution when attempting to address some scientific questions.

When Lightning Strikes Twice: Profoundly Gifted, Profoundly Accomplished

The educational, occupational, and creative accomplishments of the profoundly gifted participants (IQs ⩾ 160) in the Study of Mathematically Precocious Youth (SMPY) are astounding, but are they representative of equally able 12-year-olds? Duke University’s Talent Identification Program (TIP) identified 259 young adolescents who were equally gifted. By age 40, their life accomplishments also were extraordinary: Thirty-seven percent had earned doctorates, 7.5% had achieved academic tenure (4.3% at research-intensive universities), and 9% held patents; many were high-level leaders in major organizations. As was the case for the SMPY sample before them, differential ability strengths predicted their contrasting and eventual developmental trajectories—even though essentially all participants possessed both mathematical and verbal reasoning abilities far superior to those of typical Ph.D. recipients. Individuals, even profoundly gifted ones, primarily do what they are best at. Differences in ability patterns, like differences in interests, guide development along different paths, but ability level, coupled with commitment, determines whether and the extent to which noteworthy accomplishments are reached if opportunity presents itself.

Gifted Students’ Implicit Beliefs About Intelligence and Giftedness

Growing attention is being paid to individuals’ implicit beliefs about the nature of intelligence. However, implicit beliefs about giftedness are currently underexamined. In the current study, we examined academically gifted adolescents’ implicit beliefs about both intelligence and giftedness. Overall, participants’ implicit beliefs about giftedness and intelligence were significantly positively correlated while also having statistically significant mean differences, suggesting that they perceived the nature of the two constructs differently. Specifically, many students viewed intelligence as malleable (incremental view) and giftedness as fixed (entity view), whereas very few students viewed giftedness as malleable and intelligence as fixed; however, heterogeneity was observed. The beliefs identified in the current study provide important insight into the domain-specific nature of implicit beliefs of gifted students and suggest that caution be used against using terms like giftedness and intelligence interchangeably.

High-Ability Students’ Time Spent Outside the Classroom:

This study considered how three groups of academically talented high school students—those who attended an academic summer program (TIP), those who qualified for the program but chose not to attend (QNA), and those who did not qualify (DNQ)—spent time outside the classroom. These groupings differentiated students by ability (QNA vs. DNQ) and attendance (TIP vs. QNA). Male–female comparisons were also conducted. By comparing participation rates across a variety of activities and by sex, the current study helps explain the lives of high-ability students outside the arena by which they are defined: their academic ability. Results reveal numerous group and sex differences based on how high-ability students spend their time outside the classroom. Females tended to participate more than males in activities that were generally positively associated with academic achievement, while also participating in more types of activities. Males, however, reported watching more TV and were less likely to participate in any activity. QNA students reported spending more time on academic-related activities, such as homework and academic clubs, than did DNQ students, indicating a generally higher interest in academic endeavors. However, the QNA and TIP groups differed only in their service club participation rates, indicating that attending a summer program is not associated with spending time outside the classroom differently during the school year. This research underscores the heterogeneity of different groups of high-ability students and suggests some caution when generalizing from research findings based only on program participants. Knowing how students spend their time can help parents, educators, and researchers understand and foster adolescent development.

An Introduction to Replication Research in Gifted Education Shiny and New Is Not the Same as Useful

This methodological brief introduces readers to replication methods and their uses. Broadly defined, replication is the duplication of previously conducted research to verify or expand the original findings. Replication is particularly useful in the gifted education context because so much education theory and research are based on general education students and environments; the extent to which this prior work extends to gifted education contexts needs to be evaluated. The rationale, definition, implementation methods, and current state of replication in the social sciences generally, as well as in giftedness and creativity research specifically, are reviewed. Finally, guidance for conducting replications is provided, including recommendations on selecting important topics, engaging original authors, ensuring sufficient power, using appropriate measures and analyses, framing the manuscript, and submission planning.
