Genetic and Environmental Etiologies of the Longitudinal Relations Between Prereading Skills and Reading

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming.     

When and How Do Students Benefit From Ethnic Diversity in Middle School?

The effects of school‐based ethnic diversity on student well‐being and race‐related views were examined during the first year in middle school. To capture the dynamic nature of ethnic exposure, diversity was assessed both at the school‐level (n = 26) and based on academic course enrollments of African American, Asian, Latino, and White students (n = 4,302; M = 11.33 years). Across all four pan‐ethnic groups, school‐level ethnic diversity was associated with lower sense of vulnerability (i.e., feeling safer, less victimized, and less lonely) as well as perceptions of teachers’ fair and equal treatment of ethnic groups and lower out‐group distance. Underscoring the role of individual experiences, exposure to diversity in academic classes moderated the association between school‐level diversity and the two aforementioned race‐related views.     

Psychosocial Benefits of Cross‐Ethnic Friendships in Urban Middle Schools

To examine the unique functions of same‐ and cross‐ethnic friendships, Latino (n = 536) and African American (n = 396) sixth‐grade students (M_age = 11.5 years) were recruited from 66 classrooms in 10 middle schools that varied in ethnic diversity. Participants reported on the number of same‐ and cross‐ethnic friends, perceived vulnerability, friendship quality, and the private regard dimension of ethnic identity. Whereas same‐ethnic friendships were uniquely associated with stronger private regard, more ethnic diversity and cross‐ethnic friendships were uniquely associated with less perceived vulnerability. Multilevel structural equation modeling tested whether cross‐ethnic friendships mediated the diversity‐vulnerability relation. Although cross‐ethnic friendships did not significantly mediate this relation at the classroom level, these friendships predicted less vulnerability at the individual student level.     

Prevention: Necessary But Insufficient? A 2-Year Follow-Up of an Effective First-Grade Mathematics Intervention

We present first-grade, second-grade, and third-grade impacts for a first-grade intervention targeting the conceptual and procedural bases that support arithmetic. At-risk students (average age at pretest = 6.5) were randomly assigned to three conditions: a control group (n = 224) and two variants of the intervention (same conceptual instruction but different forms of practice: speeded [n = 211] vs. nonspeeded [n = 204]). Impacts on all first-grade content outcomes were significant and positive, but no follow-up impacts were significant. Many intervention children achieved average mathematics achievement at the end of third grade, and prior math and reading assessment performance predicted which students will require sustained intervention. Finally, projecting impacts 2 years later based on nonexperimental estimates of effects of first-grade math skills overestimates long-term intervention effects.     

Longitudinal Relations Among Parents' Reactions to Children's Negative Emotions,Effortful Control,and Math Achievement in Early Elementary School

Panel mediation models and fixed‐effects models were used to explore longitudinal relations among parents' reactions to children's displays of negative emotions, children's effortful control (EC), and children's math achievement (N = 291; M age in fall of kindergarten = 5.66 years, SD = .39 year) across kindergarten through second grade. Parents reported their reactions and children's EC. Math achievement was assessed with a standardized achievement test. First‐grade EC mediated the relation between parents' reactions at kindergarten and second‐grade math achievement, beyond stability in constructs across study years. Panel mediation model results suggested that socialization of EC may be one method of promoting math achievement in early school; however, when all omitted time‐invariant covariates of EC and math achievement were controlled, first‐grade EC no longer predicted second‐grade math achievement.     

Evaluating a bedside tool for neuroanatomical localization with extended‐matching questions

Neuroanatomical localization (NL) is a key skill in neurology, but learners often have difficulty with it. This study aims to evaluate a concise NL tool (NLT) developed to help teach and learn NL. To evaluate the NLT, an extended‐matching questions (EMQ) test to assess NL was designed and validated. The EMQ was validated with fourth‐year medical students and internal medicine and neurology residents. The NLT's usability was evaluated with third‐ and fourth‐year students, and the effectiveness was evaluated with an experimental study of second‐year students, using the EMQ as the outcome measure. Students were taught how to use both the NLT and textbook algorithms (control) to perform NL, then randomized into either group, and only allowed to use their assigned tool to complete the EMQ. Primary outcome was the difference in mean EMQ scores expressed as a percentage of total score. For EMQ validation, students (n = 56) scored lower than residents (n = 50) (76.7% ± 1.7 vs. 83.0% ± 1.6; mean ± standard error of mean, P < 0.009). The EMQ demonstrated good reliability (Cronbach's α 0.85) and generalizability (G‐coefficient 0.85). Third‐ (n = 77) and fourth‐year (n = 42) students found the NLT user‐friendly and helpful in their learning of NL. In the experimental study, scores were significantly higher for NLT group (n = 94) than for controls (n = 101) (42.5 vs. 37.0%, P = 0.014); the effect size (Cohen's d) was 0.36. The EMQ is validated to reliably assess NL and is generalizable, feasible, practical, and of low cost. The concise and user‐friendly NLT for NL was effective in aiding medical student performance of NL. Anat Sci Educ 11: 262–269. © 2017 American Association of Anatomists.     

Spelling deficits in dyslexia: evaluation of an orthographic spelling training

Orthographic spelling is a major difficulty in German-speaking children with dyslexia. The aim of the present study was to evaluate the effectiveness of an orthographic spelling training in spelling-disabled students (grade 5 and 6). In study 1, ten children (treatment group) received 15 individually administered weekly intervention sessions (60 min each). A control group (n = 4) did not receive any intervention. In study 2, orthographic spelling training was provided to a larger sample consisting of a treatment group (n = 13) and a delayed treatment control group (n = 14). The main criterion of spelling improvement was analyzed using an integrated dataset from both studies. Repeated-measures analysis of variance revealed that gains in spelling were significantly greater in the treatment group than in the control group. Statistical analyses also showed significant improvements in reading (study 1) and in a measure of participants’ knowledge of orthographic spelling rules (study 2). The findings indicate that an orthographic spelling training enhances reading and spelling ability as well as orthographic knowledge in spelling-disabled children learning to spell a transparent language like German.     

Loss of Institutional Trust Among Racial and Ethnic Minority Adolescents: A Consequence of Procedural Injustice and a Cause of Life‐Span Outcomes

This research tested a social‐developmental process model of trust discernment. From sixth to eighth grade, White and African American students were surveyed twice yearly (ages 11–14; Study 1, N = 277). African American students were more aware of racial bias in school disciplinary decisions, and as this awareness grew it predicted a loss of trust in school, leading to a large trust gap in seventh grade. Loss of trust by spring of seventh grade predicted African Americans’ subsequent discipline infractions and 4‐year college enrollment. Causality was confirmed with a trust‐restoring “wise feedback” treatment delivered in spring of seventh grade that improved African Americans’ eighth‐grade discipline and college outcomes. Correlational findings were replicated with Latino and White students (ages 11–14; Study 2, N = 206).     

Training Basic Visual Attention Leads to Changes in Responsiveness to Social‐Communicative Cues in 9‐Month‐Olds

This study investigated transfer effects of gaze‐interactive attention training to more complex social and cognitive skills in infancy. Seventy 9‐month‐olds were assigned to a training group (n = 35) or an active control group (n = 35). Before, after, and at 6‐week follow‐up both groups completed an assessment battery assessing transfer to nontrained aspects of attention control, including table top tasks assessing social attention in seminaturalistic contexts. Transfer effects were found on nontrained screen‐based tasks but importantly also on a structured observation task assessing the infants’ likelihood to respond to an adult's social‐communication cues. The results causally link basic attention skills and more complex social‐communicative skills and provide a principle for studying causal mechanisms of early development.     

Linguistic and Spatial Skills Predict Early Arithmetic Development via Counting Sequence Knowledge

Utilizing a longitudinal sample of Finnish children (ages 6–10), two studies examined how early linguistic (spoken vs. written) and spatial skills predict later development of arithmetic, and whether counting sequence knowledge mediates these associations. In Study 1 (N = 1,880), letter knowledge and spatial visualization, measured in kindergarten, predicted the level of arithmetic in first grade, and later growth through third grade. Study 2 (n = 378) further showed that these associations were mediated by counting sequence knowledge measured in first grade. These studies add to the literature by demonstrating the importance of written language for arithmetic development. The findings are consistent with the hypothesis that linguistic and spatial skills can improve arithmetic development by enhancing children's number‐related knowledge.     

Late Emergence of the First Possession Heuristic: Evidence From a Small‐Scale Culture

Western preschool children often assign ownership based on first possession and some theorists have proposed that this judgment might be an early emerging, innate bias. Five‐ to 9‐year‐olds (n = 112) from a small‐scale group in Kenya (Kikuyu) watched videotaped interactions of two women passing an object. The object's starting position and the women's gestures were varied. Use of the first possession heuristic increased with age, and 8‐ to 9‐year‐olds performed similarly to German 5‐year‐olds (n = 24). Starting position and gestures had no effect. A control study confirmed that 5‐year‐old Kikuyus (n = 20) understood the video material. The findings reveal that the first possession heuristic follows different developmental trajectories cross‐culturally and stress the role of children's sociocultural environment.     

Developmental Trajectories of Maladaptive Perfectionism Among African American Adolescents

This study examined the developmental trajectories of maladaptive perfectionism over a 7‐year period among African American youth living in an urban setting (N = 547). In particular, the study attempted to determine whether two maladaptive aspects of perfectionism (socially prescribed and self‐critical) changed over time and could be distinguished by variables in 6th and 12th grades (M_age at study entry [first grade] was 6.22 years [SD = 0.34]). Four classes best described the developmental trajectories on both measures of maladaptive perfectionism: high, low, increasing, and decreasing. Sixth‐ and 12th‐grade correlates, including measures of internalizing symptoms, mostly confirmed the distinctiveness of these classes. Parallel process analyses suggested that the two processes are complementary, yet distinct. Implications regarding the prevention of maladaptive perfectionism are discussed.     

Learner engagement in MOOCs: Scale development and validation

The purpose of this study is to contribute to a better understanding of the complexity of conceptualising and measuring learner engagement in Massive Open Online Courses (MOOCs). The paper develops and validates a MOOC engagement scale (MES) to measure learner engagement. The initial questionnaire items of the scale were developed by reviewing existing related literature and validated student engagement constructs. This was followed by a modified scale development process, including two focus group interviews (n = 10), an exploratory survey (n = 12), an expert review (n = 10), a pilot survey (n = 15), an item purification study (n = 590) and a construct validation study (n = 303). The final version of the scale is made up of four dimensions: behavioural engagement, cognitive engagement, emotional engagement and social engagement. The paper concludes with recommendations for how the MES can be used to assess the pattern of engagement in MOOCs and to investigate the relationship between learner engagement and other important MOOC teaching and learning factors.     

Learning to Individuate: The Specificity of Labels Differentially Impacts Infant Visual Attention

This study examined differences in visual attention as a function of label learning from 6 to 9 months of age. Before and after 3 months of parent‐directed storybook training with computer‐generated novel objects, event‐related potentials and visual fixations were recorded while infants viewed trained and untrained images (n = 23). Relative to a pretraining, a no‐training control group (n = 11), and to infants trained with category‐level labels (e.g., all labeled “Hitchel”), infants trained with individual‐level labels (e.g., “Boris,” “Jamar”) displayed increased visual attention and neural differentiation of objects after training.     

The Role of Mediators in the Development of Longitudinal Mathematics Achievement Associations

Despite research demonstrating a strong association between early and later mathematics achievement, few studies have investigated mediators of this association. Using longitudinal data (n = 1,362), this study tested the extent to which mathematics self‐concepts, school placement, executive functioning, and proficiency in fractions and division account for the association between mathematics achievement in first grade and at age 15. As hypothesized, a strong longitudinal association between first‐grade and adolescent mathematics achievement was present (β = .36) even after controlling for a host of background characteristics, including cognitive skills and reading ability. The mediators accounted for 39% of this association, with mathematics self‐concept, gifted and talented placement, and knowledge of fractions and division serving as significant mediators.     

Maternal Support of Children's Early Numerical Concept Learning Predicts Preschool and First‐Grade Math Achievement

The primary goal in this study was to examine maternal support of numerical concepts at 36 months as predictors of math achievement at 4½ and 6‐7 years. Observational measures of mother–child interactions (n = 140) were used to examine type of support for numerical concepts. Maternal support that involved labeling the quantities of sets of objects was predictive of later child math achievement. This association was significant for preschool (d = .45) and first‐grade math (d = .49), controlling for other forms of numerical support (identifying numerals, one‐to‐one counting) as well as potential confounding factors. The importance of maternal support of labeling set sizes at 36 months is discussed as a precursor to children's eventual understanding of the cardinal principle.     

Developmental Relations Between Vocabulary Knowledge and Reading Comprehension: A Latent Change Score Modeling Study

The present study followed a sample of first‐grade (N = 316, M_age = 7.05 at first test) through fourth‐grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and reading comprehension to test for the presence of leading and lagging influences. Univariate models indicated growth in vocabulary knowledge, and reading comprehension was determined by two parts: constant yearly change and change proportional to the previous level of the variable. Bivariate models indicated previous levels of vocabulary knowledge acted as leading indicators of reading comprehension growth, but the reverse relation was not found. Implications for theories of developmental relations between vocabulary and reading comprehension are discussed.     

The Ghost in the Touchscreen: Social Scaffolds Promote Learning by Toddlers

This study examined the effect of a “ghost” demonstration on toddlers’ imitation. In the ghost condition, virtual pieces moved to make a fish or boat puzzle. Fifty‐two 2.5‐ and 3‐year‐olds were tested on a touchscreen (no transfer) or with 3D pieces (transfer); children tested with 3D pieces scored above a no demonstration baseline, but children tested on the touchscreen did not. Practice on the touchscreen (n = 23) by 2.5‐ and 3‐year‐olds prior to the ghost demonstration did not improve performance. Finally, children who learned the puzzle task via a social demonstration and were tested on the touchscreen (n = 26) performed better than the ghost conditions. Taken together, these studies demonstrate that social demonstrations enhance learning from novel touchscreen tools during early childhood.     

The development of place value concepts: Approximation before principles

Place value concepts were measured longitudinally from kindergarten (2017) to first grade (2018) in a diverse sample (n = 279; M_age = 5.76 years, SD = 0.55; 135 females; 41% Black, 38% White, 8% Asian, 12% Latino). Children completed three syntactic tasks that required an explicit understanding of base-10 symbols and three approximate tasks that could be completed without this explicit understanding. Approximate performance was significantly better in both age groups. A factor analysis confirmed that syntactic and approximate tasks tapped separate latent variables in kindergarten, but not in first grade. Path analyses indicated that only kindergarten approximate performance predicted overall first-grade place value understanding. These findings suggest that explicit understanding of base-10 principles develops from implicit, partial knowledge of multidigit numbers.     

Ethnic Differences in Associations Among Popularity,Likability, and Trajectories of Adolescents' Alcohol Use and Frequency

Two‐part latent growth models examined associations between two forms of peer status (popularity, likability) and adolescents' alcohol use trajectories throughout high school; ethnicity was examined as a moderator. Ninth‐grade low‐income adolescents (N = 364; M_age = 15.08; 52.5% Caucasian; 25.8% African American; 21.7% Latino) completed sociometric nominations of peer status and aggression at baseline, and reported their alcohol use every 6 months. After controlling for gender, aggression, ethnicity, and socioeconomic status, popularity—but not likability—prospectively predicted alcohol use trajectories. However, these effects were moderated by ethnicity, suggesting popularity as a risk factor for alcohol use probability and frequency among Caucasian and Latino, but not African American adolescents. Results suggest that developmental correlates of peer status should be considered within cultural context.
