The Cognitive Predictors of Computational Skill with Whole versus Rational Numbers: An Exploratory Study

The purpose of the present study was to explore the 3rd-grade cognitive predictors of 5th-grade computational skill with rational numbers and how those are similar to and different from the cognitive predictors of whole-number computational skill. Students (n = 688) were assessed on incoming whole-number calculation skill, language, nonverbal reasoning, concept formation, processing speed, and working memory in the fall of 3rd grade. Students were followed longitudinally and assessed on calculation skill with whole numbers and with rational numbers in the spring of 5th grade. The unique predictors of skill with whole-number computation were incoming whole-number calculation skill, nonverbal reasoning, concept formation, and working memory (numerical executive control). In addition to these cognitive abilities, language emerged as a unique predictor of rational-number computational skill.     

Planning Improves Vocal Fluency and the Appearance of Concern When Communicating Emotional Support

Emotional support is often conveyed to people with cancer; however, not all support messages are effective, leading some potential supporters to fear appearing incompetent when communicating support. Additionally, nonverbal behaviors, such as vocal fluency, pitch variety, eye contact, and conveying concern, have previously been associated with support recipients’ outcomes and perceptions of speaker competence. This experiment determines whether these nonverbal behaviors can be increased through message planning. Participants were randomly assigned to either a planning condition or a distraction task condition before recording emotional support messages for a friend hypothetically diagnosed with cancer. Results showed that planners spoke with significantly more vocal fluency and conveyed significantly more nonverbal concern than nonplanners. Planners also used more eye contact and pitch variety than nonplanners, but these differences were not statistically significant. Results suggest that planning may improve some nonverbal aspects of communicating support, which may in turn improve perceptions of supporters’ competence.     

Approaches to teaching in higher education: the perspective of network analysis using the revised approaches to teaching inventory

Higher Education - Over time, the academics’ approaches to teaching (i.e., content- or learning-focused approach) were intensively studied. Traditionally, studies estimated the shared...     

Racial/ethnic differences in Medicaid expenditures on psychotropic medications among maltreated children

This study quantifies racial/ethnic differences in Medicaid expenditures on psychotropic drugs among a national sample of children with suspected maltreatment. We linked 4,445 child participants in the National Survey of Child and Adolescent Well-Being (NSCAW) – consisting of children investigated for suspected abuse and neglect – to their Medicaid claims obtained from 36 states. We used propensity score matching to construct a comparison group of children without known child welfare involvement, and estimated two-part generalized linear models to examine differences in annual psychotropic drug expenditures per child between children of different races/ethnicities. When compared to a matched sample of children, African American and Latino children incur $292 and $144 less expenditures on psychotropic drugs, respectively, than white children. Among NSCAW children alone, African American children display $614 less spending on psychotropic drugs when compared to white children. Racial/ethnic differences in expenditures on psychotropic drugs occur among all children on Medicaid, but the differences are especially pronounced among African American children in contact with the child welfare system. These findings demonstrate that policymakers will need to pay special attention to the needs of children of color as Medicaid expansions proceed nationwide.     

Student perceptions of the classroom environment: Relations to motivation and achievement in mathematics

This study examined the relationship of 979 middle school students’ perceptions of their mathematics classroom environment to their motivation and achievement. Structural equation modeling indicated that motivational variables (utility, personal achievement goals, efficacy) mediated the influence of perceived teacher expectations, teacher support and use of reform practices on mathematics standardised test scores. Our study provides empirical evidence that students’ perceptions that their teachers believe that they are capable of learning and understanding mathematics positively relate to their Mastery and Performance Goal orientations and mathematics Utility. Further, we found an interaction between students’ perceptions of the frequency of reform practice use in their mathematics classroom and mathematics efficacy. For students with lower mathematics efficacy, their perceptions of more frequent use of reform practices in their mathematics class related to higher standardised test performance. For students with higher mathematics efficacy, perceived use of reform practices did not significantly relate to standardised test performance. These data suggest that frequent exposure to reform practices is especially critical for students who judge themselves as being less capable in mathematics and who are lower performers. This finding differs from prior research that has suggested that reform practice use benefits higher achievers but not lower achievers. An important implication of our study is the need for coordinated, ongoing professional development that highlights reform pedagogy and beliefs while also focusing on student motivation theories and strategies.     

The role of the athletes’ entourage on attitudes to doping

ABSTRACT

The present study investigated athletes’ and coaches’ beliefs about the role of athletes’ entourage in deterring or promoting doping. Competitive athletes and coaches in Greece and Australia took part in semi-structured interviews. Our analysis of the interviews produced five main themes: coach influence, peer influence, doping stance, doping stigma, and entourage’s culture. Overall, coaches and peers having a close and trusty relationship with the athletes were considered most influential with respect to doping-related decisions. The majority of the athletes held a strong anti-doping stance but could not articulate why they held this position. This inability could be ascribed to the stigmatization of doping which led to lack of knowledge and anti-doping education. Finally, an anti-doping culture in the athletes’ environment was considered central to an anti-doping stance. The study findings provide valuable information towards a comprehensive understanding of the role athletes’ entourage can play in shaping athletes’ attitudes and decision for doping.     

The Relationship between Civic Behavior and Civic Values: A Conceptual Model

This study examined the relationships among college students’ civic values and behaviors, college culture, and college involvement, accounting for their pre-college inclinations toward civic responsibility. Using a longitudinal, national dataset comprised of 3,680 college students, the study employed structural equation modeling to identify a model that suggests social activism goals mediate the relationship between co-curricular engagement and charitable involvement behaviors.     

Supplementing literacy instruction with a media-rich intervention: Results of a randomized controlled trial

This study investigates whether a curriculum supplement organized as a sequence of teacher-led literacy activities using digital content from public educational television programs can improve early literacy outcomes of low-income preschoolers. The study sample was 436 children in 80 preschool classrooms in California and New York. Preschool teachers were randomly assigned to implement either a 10-week media-rich early literacy intervention that employed clips from Sesame Street, Between the Lions, and SuperWhy! or to a comparison condition. The media-rich literacy supplement had positive impacts (+0.20 ≤ d ≤ +0.55) on children's ability to recognize letters, sounds of letters and initial sounds of words, and children's concepts of story and print. The study findings show the potential for incorporating literacy content from public media programming into curriculum supplements supported by professional development to impact early literacy outcomes of low-income children.
