Weight changes in children in foster care for 1 year

Objective

The aims of this study of predominately racial/ethnic minority children in foster care (N = 360, birth to 19 years old) in Los Angeles, CA were to examine the (1) prevalence of obesity (≥95 percentile) and overweight/obese (≥85 percentile) upon entrance to foster care (T1) and after 1 year in foster care (T2); (2) comparison of high weight categories to national statistics; (3) relationship of changes in weight status to age, reason for entry into foster care, and placement.

Methods

Chi-square test and McNemar test comparing paired proportions were used to determine whether there were significant changes in the proportion of high weight categories between T1 and T2. Chi-square test or Fisher's exact test were used to evaluate the association between age, placement, and reason for foster care with the change in weight category. Changes in weight were categorized as (1) decreased in weight, (2) remained at overweight or obese, (3) increased in weight, or (4) remained normal.

Results

The proportion of obese and obese/overweight children between ages 2 and 5 were significantly lower at T2 than T1. There were no significant changes in the prevalence of obesity for the total population at T2. Children age 6 or older had a higher prevalence of obesity and overweight/obesity compared to national statistics. Of children at all ages, 64.7% of children of all ages entered foster care with a normal weight and stayed in the normal range during their first year in foster care, 12.2% decreased their weight, 15.4% remained overweight or obese, and 7.7% increased their weight. Age and parental substance use was related to change in weight category from T1 to T2.

Conclusion

Children did not become more overweight or obese in foster care; however 28% of the children were obese or overweight upon entry into foster care. Children who are 6 years or older and obese upon entering foster care should be targeted for weight reduction. The pediatric community and child welfare system need to work together by including weight percentiles in the foster care file and training/monitoring child welfare caregivers in weight reduction interventions.     

Using new vocabulary in writing: Exploring how word and learner characteristics relate to the likelihood that writers use newly taught vocabulary

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word’s orthography, phonology, and semantics based on the word’s characteristics. In addition, a learner’s overall literacy skills should relate to whether they attempt to use words. In the present study, sixth graders (n = 66), seventh graders (n = 60), and eighth graders (n = 41) learned 25 academic vocabulary words in a supplementary academic vocabulary intervention and were then asked to use those words in short persuasive essay drafts. We measured whether these students attempted to use a word (a binary uses outcome) and the number of times a student used a word (a continuous attempts outcome) and used cross-classified random effects models to examine how (a) the orthographic, phonological, and semantic characteristics of words and (b) the students’ literacy-related characteristics related to their uses and attempts. For word characteristics, students were more likely to use and attempt high frequency than low frequency words. For student characteristics, students proficient on the state exam were more likely to use and attempt the words, and students learning English were less likely to attempt the words. Implications for vocabulary intervention and writing instruction are discussed.     

Blocking in autoshaped lever-pressing procedures with rats

Rats will approach and contact a lever whose insertion into the chamber signals response-independent food delivery. This “autoshaping” or “sign-tracking” phenomenon has recently attracted considerable attention as a platform for studying individual differences in impulsivity, drug sensitization, and other traits associated with vulnerability to drug addiction. Here, we examined two basic stimulus selection phenomena—blocking and overshadowing—in the autoshaped lever pressing of rats. Blocking and overshadowing were decidedly asymmetrical. Previously reinforced lever-extension conditioned stimuli (CSs) completely blocked conditioning to auditory cues (Exps. 1 and 2), and previously nonreinforced lever-extension CSs overshadowed conditioning to auditory cues. By contrast, conditioning to lever-extension CSs was not blocked by either auditory (Exp. 3) or lever-insertion (Exp. 4) cues, and was not overshadowed by auditory cues. Conditioning to a lever-insertion cue was somewhat overshadowed by the presence of another lever, especially in terms of food cup behavior displayed after lever withdrawal. We discuss several frameworks in which the apparent immunity of autoshaped lever pressing to blocking might be understood. Given evidence that different brain systems are engaged when different kinds of cues are paired with food delivery, it is worth considering the possibility that interactions among them in learning and performance may follow different rules. In particular, it is intriguing to speculate that the roles of simple cue–reinforcer contiguity, as well as of individual and aggregate reinforcer prediction errors, may differ across stimulus classes.     

Web 2.0 Technologies and Back Channel Communication in an Online Learning Community

Communication, collaboration and community development are processes that contribute to student satisfaction and learning in online courses. This paper describes a study that investigated how campus and distance graduate students in a library science program communicated with one another outside the official boundaries of their courses. We conducted a survey to answer two research questions: 1) What Web 2.0 technologies do students use to communicate with one another outside of the formal structure of their online courses? and 2) What do they talk about in such communication? The results showed that, while students used a variety of technologies to communicate with one another, those enrolled at a distance made greater use of technology to communicate with one another. Moreover, clear preferences emerged according to age. Younger students preferred mobile technologies while older students experimented with a wider range of web-based technologies. We interpret these results and offer recommendations for practice based on our interpretation.     

Implementation of Bug-in-Ear Coaching by Community-Based Professional Development Providers

Research Findings: Bug-in-ear coaching implemented under highly controlled situations has a promising research base. Yet few researchers have examined its effects when implemented within less controlled environments using authentic professional development conditions. The purpose of this study was to examine the implementation and effects of bug-in-ear coaching when staff from a community organization served as community coaches for early childhood educators. We found that community coaches implemented bug-in-ear methods, but additional supports may be necessary to increase the intensity and quality of feedback provided. Effects of the intervention were observed for 1 of the 6 targeted outcomes for educators. However, effects did not translate to children’s communication outcomes. Practice or Policy: Bug-in-ear coaching is 1 method of providing early childhood educators with performance-based feedback. One benefit is that while community coaches observe educators live, they provide feedback that educators can immediately use to improve practice. However, bug-in-ear coaching poses challenges with respect to reviewing goals and reflecting on one’s performance. Community coaches and educators should systematically plan for reflection so that educators can create new implementation goals to improve their practice. Changing educator practice is a complex endeavor, but bug-in-ear coaching is a promising tool for doing so in a supportive manner.     

A Statewide Analysis of North Carolina Public Libraries and Their Response to the Opioid Epidemic

ABSTRACT

This study sought to investigate the opioid epidemic impact on North Carolina public libraries. Libraries in half of all 100 counties were chosen through a random, geographically systematic process, and structured interviews were completed with library directors. Twenty directors were interviewed, representing 28 counties. All reported their communities were affected; nine reported direct impacts on library function. Fifteen directors felt libraries should be involved in response; some felt Narcan administration was beyond library purview. Two libraries reported having Narcan available; five reported providing staff training. Given librarians’ willingness to respond, it is time to provide necessary support for those efforts.     

Does the Arrangement of Embedded Text Versus Linked Text in Homework Systems Make a Difference in Students Impressions,Attitudes, and Perceived Learning?

Students in a first-semester general chemistry course at a large southwestern university completed a 3-week homework assignment using MindTap, a Cengage Learning product. MindTap is the first major electronic system that has homework questions embedded in the text, such that students read a short section of the textbook and then answer a question set. Prior to MindTap, electronic homework systems were stand-alone or contained questions with links to the textbook. Next, students completed two 2-week homework assignments in Online Web Learning (OWL) version 1 also from Cengage Learning. The OWL system shows homework questions with a link to the textbook in a separate window. Both the MindTap and OWL systems contain the same or similar questions. After the students used both homework systems, a survey was given that included Likert-scaled and open-response questions that dealt with students’ perceived level of understanding using the different systems, how easy the systems were to use, and the advantages/disadvantages of each system. A delayed survey was given at the end of the second semester of general chemistry, during which students had used OWL for the complete semester. This paper investigates the effects of the arrangement (embedded vs. linked) on student preferences and perceived learning in this pilot study with a 300-person class. Based on the results of the study, it was found that students perceived that they learn more with MindTap and prefer the embedded text in MindTap over the linked text in OWL.     

Narratives of ‘doing,knowing, being and becoming’: examining the impact of an attachment-informed approach within initial teacher education

The Scottish Government’s vision of improving outcomes for children prioritises attachment theory and research in promoting children’s well-being across children’s services. This theme is also noted as increasing international relevance. Our narrative research springs from the experience of designing and delivering the first course within initial teacher education in Scotland to focus on the application of attachment theory to the role and identity of the teacher – particularly, in supporting children vulnerable through experiences of trauma and adversity. We capture students’ ‘real time’ learning moments through reflective journaling during school experience within the analytic ‘Doing, knowing, being and becoming’. Emergent themes include: looking behind and responding to behaviours, making links with ‘lived lives’, understanding teachers’ potential as attachment figures and ‘secure base’, understanding the relevance of adult attachment theory and resilience/self-care to teachers’ emotions and their own attachment experiences.     

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.     

One size does not fit all: Understanding the variation in charter management scale-up

The prevalence of charter management organizations (CMOs)—networks of charter schools overseen by a home office—has exploded in recent years but there is a paucity of research into how CMOs approach growth and the factors that influence their growth plans. In this qualitative study, we examine how a set of 25 older, more established CMOs approached growth. Findings suggest that strategies for scale-up varied depending on the external policy environment and the internal organizational capacity of the CMO. In addition, CMOs approached growth from one of three styles: premeditated, opportunistic, or organic. Finally, longitudinal data reveal that CMOs often struggled to meet their growth targets; fewer than half of the sample CMOs met or were on track to meet their projected scale-up targets. From these findings emerged a key source of tension: On one hand, CMOs are facing pressure from policymakers and foundations to grow and expand rapidly. On the other hand, scaling-up too quickly or in ways that fall outside of the CMO’s mission can lead to serious consequences for the organization, its schools, and students. Our research aims to contribute to this debate by demonstrating that “one size does not fit all” for CMO scale-up, a lesson important for policymakers, educators, and researchers alike.
