Effects of a Supplemental Vocabulary Intervention on the Word Knowledge of Kindergarten Students At Risk for Language and Literacy Difficulties

The purpose of this study was to examine the effectiveness of a vocabulary intervention designed to supplement research‐based classroom vocabulary instruction, implemented with students who may be at risk for language and learning difficulties. Participants included 43 kindergarten students who received research‐based classroom vocabulary instruction. Students with the 20 lowest scores on the Peabody Picture Vocabulary Test‐III administered at pretest received additional small‐group supplemental vocabulary intervention. Results of within‐subjects comparisons indicated that, overall, at‐risk students made greater gains in word knowledge on target words that received the supplemental intervention as compared to words that received only classroom‐based instruction. In addition, at‐risk students who received the supplemental intervention demonstrated word‐learning gains that approached those of their peers who received classroom instruction alone. Implications along with limitations of the current study and directions for future research are discussed.     

Validity of Activity Trackers in Estimating Energy Expenditure During High-Intensity Functional Training

ABSTRACT

Purpose: The purpose of this study was to evaluate the agreement of five commercially available accelerometers in estimating energy expenditure while performing an acute bout of high-intensity functional training (HIFT). Methods: Participants (n = 47; average age: 28.5 ± 11.6 years) consisted of recreationally active, healthy adults. Each participant completed a session of HIFT: a 15-minute workout consisting of 12 repetitions each of air-squats, sit-ups, push-ups, lunges, pull-ups, steps-ups, and high-knees; performed circuit-style by completing as many rounds as possible. During this session, each participant wore the Cosmed K4b2 portable metabolic analyzer (PMA) and five different accelerometers (ActiGraph GT3X, Nike Fuelband, Fitbit One, Fitbit Charge HR, and Jawbone UP Move). Results: Four of the five activity trackers reported lower (p < .05) total EE values compared to the PMA during the acute bout of HIFT. The waist-mounted device (ActiGraph, 182.55 ± 37.93 kcal) was not significantly different from, and most closely estimated caloric expenditure compared to the PMA (144.99 ± 37.13 kcal) (p = .056). A repeated-measures ANOVA showed that all activity trackers were significantly different from the reference measure (PMA) (p < .05). Systematic relative agreement between the activity trackers was calculated, exhibiting a significant ICC = 0.426 (F [46,230] = 5.446 [p < .05]). Conclusion: The wrist- and hip-mounted activity trackers did not accurately assess energy expenditure during HIFT exercise. With the exception of the ActiGraph GT3X, the remaining four activity trackers showed inaccurate estimates of the amount of kilocalories expended during the HIFT exercise bout compared to the PMA.     

Teaching Through Collaboration: Flexibility and Diversity in Caregiver–Child Interaction Across Cultures

Teaching supports the high-fidelity transmission of knowledge and skills. This study examined similarities and differences in caregiver teaching practices in the United States and Vanuatu (N = 125 caregiver and 3- to 8-year-old child pairs) during a collaborative problem-solving task. Caregivers used diverse verbal and nonverbal teaching practices and adjusted their behaviors in response to task difficulty and child age in both populations. U.S. caregivers used practices consistent with a direct active teaching style typical of formal education, including guiding children’s participation, frequent praise, and facilitation. In contrast, Ni-Vanuatu caregivers used practices associated with informal education and divided tasks with children based on difficulty. The implications of these findings for claims about the universality and diversity of caregiver teaching are discussed.     

Teacher-Directed Decoding Practice with Manipulative Letters and Word Reading Skill Development of Struggling First Grade Students

We compared the effects of two approaches to decoding on the word reading skills of struggling first-grade students: decontextualized, teacher directed decoding practice with manipulative letters and embedded, incidental decoding practice. Participants were 98 students at risk for reading disability. We randomly assigned participants to three groups: (1) treatment, (2) comparison, and (3) control. The treatment group received 30 sessions of small-group instruction using manipulative letters to practice decoding skills. The comparison group received the same small-group reading instruction without the additional decoding practice. The control group did not receive supplemental small-group instruction. Analyses indicated that students who received the additional decoding practice with manipulative letters scored significantly better on phonological awareness, decoding, and word recognition skills than students who received incidental decoding practice.     

Researching early intervention and young children's perspectives – developing and using a ‘listening to children approach’

This article, by Alice Paige‐Smith and Jonathan Rix, considers the current context of early intervention in England from the perspective and experiences of two families and in particular focuses on two young children identified as having Down syndrome. This case study research has emerged from previous research conducted by the authors, both of whom are Senior Lecturers at the Open University and have a wealth of experience across all phases of education. Their previous research involved interviews with parents of children diagnosed as having Down syndrome, which raised further questions about early intervention and the pedagogical relationship between the parent and the child, and recognised that ‘early intervention’ can be more than structured activities led by professionals. The research in this article, which has been funded by the British Academy, used ethnographic methodology to understand the process of early intervention with two young children with Down syndrome and their families. The methodology developed to include narrative first‐person observation of the child and photography. In addition to this a method of reflecting on the process of early intervention developed that included the researchers, the parent and the child. The development of this research methodology is considered in detail in this article.     

PRESCHOOL CHILDREN'S INTEREST,SOCIAL–EMOTIONAL SKILLS,AND EMERGENT MATHEMATICS SKILLS

This cross‐sectional study examined the relationship between interest, social–emotional skills, and early math skills in preschool children. Math‐specific interest and global interest in learning were measured using teacher report and a play‐based observation task. Math skills were assessed with a test of math achievement, and social–emotional skills were assessed using a teacher‐report measure. Children with higher global interest in learning, math‐specific interest, and observed goal‐directed play demonstrated higher math skills. Furthermore, social‐emotional skills were associated with global interest in learning and math skills, but not with math‐specific interest. Overall, findings support the relevance of interest and social‐emotional skills for school readiness in young children.
