Encouraging girls in math and science

The objective of this guide is to provide teachers with specific recommendations that can be carried out in the classroom without requiring systemic change. Other school personnel having direct contact with students, such as coaches, counselors, and principals, will also find the guide useful

Changes in United States Latino/a High School Students’ Science Motivational Beliefs: Within Group Differences Across Science Subjects, Gender, Immigrant Status, and Perceived Support

Science motivational beliefs are crucial for STEM (science, technology, engineering, and math) performance and persistence, but these beliefs typically decline during high school. We expanded the literature on adolescents’ science motivational beliefs by examining: (1) changes in motivational beliefs in three specific science subjects, (2) how gender, immigrant generation status, and perceived support from key social agents predicted differences in adolescents’ science motivational beliefs, and (3) these processes among Latino/as in the United States, whose underrepresentation in STEM is understudied. We used hierarchical linear modeling to estimate the changes in 104 (40% female) Latino/a high school students’ physics, chemistry, and biology motivational beliefs from 9th to 11th grade. Subject-specific ability self-concept, interest, and utility were regressed on gender, immigrant generation status, and perceived science support while controlling for family income, parent education, and adolescents’ school. Adolescents’ utility declined from 9th to 11th grade whereas their interest remained stable for all three science subjects. Adolescents’ ability self-concept increased for biology, decreased for physics, but remained stable for chemistry. Gender differences in adolescents’ motivational beliefs at 9th grade only emerged for physics utility as well as physics and chemistry interest; yet, there were no gender differences in how adolescents’ science motivational beliefs changed over time. Contrary to expectations, immigrant generation status was not significantly associated with adolescents’ science motivational beliefs at 9th grade or in terms of how they changed over time. Adolescents who perceived higher science support generally had higher motivational beliefs in 9th grade, but did not differ on their rate of change. Our findings highlight the need to examine specific science subjects, and that typical gender differences in adolescents’ motivational beliefs discussed in the literature may not generalize to all racial and ethnic groups

“You gotta respect”: Mexican-origin Adolescents’ Perspectives on Respect in Organized Activities

Respect is crucial for promoting participation and positive experiences in organized activities, especially among ethnically diverse youth. However, little is known regarding how Mexican-origin adolescents conceptualize respect and specifically how to promote respect in activities. Guided by theory and previous research, we used qualitative content analysis to elucidate perspectives on respect and features involved in the development of respect in activities. Our sample consisted of 18 Mexican-origin 7th graders who resided in the Southwest of the U.S., an area with a history of inter-ethnic group tensions. The adolescents in this study described three different types of respect:  humanity respect, respect for culture, and linguistic respect. Potential features involved in the development of respect were identified, including individual- (e.g., moral virtues), contextual (e.g., welcoming atmosphere), and inter-personal (e.g., shared experiences) features. This study increases out depth of understanding of respect in activities, identifies areas for researchers to pursue in future research, and unveils potential implications for designing activities that promote positive, respectful relationships

Demographic Differences in Patterns of Youth Out-of-School Time Activity Participation

Participation in structured out-of-school time (OST) activities is of growing interest to families, youth practitioners, and policymakers. OST activities benefit youth socially, emotionally, and academically, especially at-risk youth. Yet, little research has explored the characteristics of youth participants. This study examines whether demographic differences exist merely in getting youth “in the door” of activities, or whether differences persist when examining the number of activities and the amount of time youth spend in activities once they are there. Results from two nationally representative datasets showed that disadvantaged youth were less likely to participate in a variety of activities than their peers, and participated in fewer numbers of activities. Among youth who did participate, Blacks and Hispanics participated less frequently in some activities, although Blacks participated more frequently in community-based youth programs. Implications for recruitment and retention are discussed, including the need for activity leaders to enhance efforts to attract and sustain disadvantaged and ethnic minority youth

Silk garments plus standard care compared with standard care for treating eczema in children: A randomised, controlled, observer-blind, pragmatic trial (CLOTHES Trial)

© 2017 Thomas et al. Background: The role of clothing in the management of eczema (also called atopic dermatitis or atopic eczema) is poorly understood. This trial evaluated the effectiveness and cost-effectiveness of silk garments (in addition to standard care) for the management of eczema in children with moderate to severe disease. Methods and findings: This was a parallel-group, randomised, controlled, observer-blind trial. Children aged 1 to 15 y with moderate to severe eczema were recruited from secondary care and the community at five UK medical centres. Participants were allocated using online randomisation (1:1) to standard care or to standard care plus silk garments, stratified by age and recruiting centre. Silk garments were worn for 6 mo. Primary outcome (eczema severity) was assessed at baseline, 2, 4, and 6 mo, by nurses blinded to treatment allocation, using the Eczema Area and Severity Index (EASI), which was log-transformed for analysis (intention-to-treat analysis). A safety outcome was number of skin infections. Three hundred children were randomised (26 November 2013 to 5 May 2015): 42% girls, 79% white, mean age 5 y. Primary analysis included 282/300 (94%) children (n = 141 in each group). The garments were worn more often at night than in the day (median of 81% of nights [25th to 75th centile 57% to 96%] and 34% of days [25th to 75th centile 10% to 76%]). Geometric mean EASI scores at baseline, 2, 4, and 6 mo were, respectively, 9.2, 6.4, 5.8, and 5.4 for silk clothing and 8.4, 6.6, 6.0, and 5.4 for standard care. There was no evidence of any difference between the groups in EASI score averaged over all follow-up visits adjusted for baseline EASI score, age, and centre: adjusted ratio of geometric means 0.95, 95% CI 0.85 to 1.07, (p = 0.43). This confidence interval is equivalent to a difference of −1.5 to 0.5 in the original EASI units, which is not clinically important. Skin infections occurred in 36/142 (25%) and 39/141 (28%) of children in the silk clothing and standard care groups, respectively. Even if the small observed treatment effect was genuine, the incremental cost per quality-adjusted life year was £56,811 in the base case analysis from a National Health Service perspective, suggesting that silk garments are unlikely to be cost-effective using currently accepted thresholds. The main limitation of the study is that use of an objective primary outcome, whilst minimising detection bias, may have underestimated treatment effects. Conclusions: Silk clothing is unlikely to provide additional benefit over standard care in children with moderate to severe eczema. Trial registration: Current Controlled Trials ISRCTN77261365

The association between treatment adherence to nicotine patches and smoking cessation in pregnancy: a secondary analysis of a randomised controlled trial

IntroductionIn non-pregnant ‘quitters’, adherence to nicotine replacement therapy (NRT) increases smoking cessation. We investigated relationships between adherence to placebo or NRT patches and cessation in pregnancy, including an assessment of reverse causation and whether any adherence: cessation relationship is moderated when using nicotine or placebo patches. MethodsUsing data from 1050 pregnant trial participants, regression models investigated associations between maternal characteristics, adherence and smoking cessation. ResultsAdherence during the first month was associated with lower baseline cotinine concentrations (beta -0.08, 95%CI -0.15 to -0.01) and randomisation to NRT (beta 2.59, 95%CI 1.50 to 3.68). Adherence during both treatment months was associated with being randomised to NRT (beta 0.51, 95%CI 0.29 to 0.72) and inversely associated with higher nicotine dependence. Adherence with either NRT or placebo was associated with cessation at one month (OR 1.11, 95%CI 1.08 to 1.13) and delivery (OR 1.06, 95%CI 1.03 to 1.09), but no such association was observed in the subgroup where reverse causation was not possible. Amongst all women, greater adherence to nicotine patches was associated with increased cessation (OR 2.47, 95%CI 1.32 to 4.63) but greater adherence to placebo was not (OR 0.98, 95%CI: 0.44 to 2.18). ConclusionWomen who were more adherent to NRT were more likely to achieve abstinence; more nicotine dependent women probably showed lower adherence to NRT because they relapsed to smoking more quickly. The interaction between nicotine-containing patches and adherence for cessation suggests that the association between adherence with nicotine patches and cessation may be partly causal

Patterns of out-of-school time use around the world. Do they help to explain international differences in mathematics and science achievement

International studies suggest that the U.S. ranks below many Asian and European countries in the 21st century in terms of mathematics and science achievement. Few have looked beyond the classroom to understand these differences. Absolute and relative time spent in various out-of-school time (OST) activities may provide one explanation. This study used the Trends in International Mathematics and Science Study (TIMSS), which includes data on the OST and achievement of 8th graders from nearly 50 countries worldwide. OST variables included technology-based (e.g., using the internet), labor (e.g., chores), and leisure activities (e.g., sports, playing with friends). Students completed an internationally standardized mathematics and science achievement test. Results for absolute OST suggest that, beyond the large contribution of a country\u27s human development index, OST is an important predictor of achievement. Further, relative OST is an important predictor, such that, those countries whose profile of time use was highest in technology also had the highest achievement scores. Future research should consider a broader view of education and related contexts that includes understanding the variability in OST use both within and between nations. (DIPF/Orig.

Do Friends and Nonfriends Behave Differently? A Social Relations Analysis of Children’s Behavior

Children behave differently with friends and nonfriends. The goal of the current study was to examine these differences more closely with effect sizes and the Social Relations Model (SRM). One hundred twenty-three triads (target children, friends, and unacquainted peers) participated in a round-robin design during 4th grade with partial replication during 5th grade (N112). Results indicated that children’s negative behavior, positive behavior, and play sophistication with friends and nonfriends were significantly different, but the effect sizes of these differences were typically small. SRM was used to divide children’s behavior with friends and nonfriends into three components: actor, partner, and relation- ship/error. The actor and partner effects significantly accounted for variance in children’s behavior with friends and nonfriends
