Can instructional and emotional support in the first-grade classroom make a difference for children at risk of school failure?

This study examined ways in which children's risk of school failure may be moderated by support from teachers. Participants were 910 children in a national prospective study. Children were identified as at risk at ages 5-6 years on the basis of demographic characteristics and the display of multiple functional (behavioral, attention, academic, social) problems reported by their kindergarten teachers. By the end of first grade, at-risk students placed in first-grade classrooms offering strong instructional and emotional support had achievement scores and student-teacher relationships commensurate with their low-risk peers; at-risk students placed in less supportive classrooms had lower achievement and more conflict with teachers. These findings have implications for understanding the role that classroom experience may play in pathways to positive adaptation.     

Quality of Language and Literacy Instruction in Preschool Classrooms Serving At-Risk Pupils

Policy-makers, administrators, researchers, and teachers are increasingly vested in ensuring the quality of preschool instruction, particularly in the areas of language and literacy. This research was conducted to characterize the quality of language and literacy instruction in 135 publicly-funded preschool classrooms serving at-risk pupils. As all teachers in these classrooms were implementing the same language and literacy curriculum, we also studied the interrelationships among procedural fidelity to a prescribed curriculum and the quality of language and literacy instruction, determining whether procedural fidelity is associated or disassociated with quality instruction. Results showed that the quality of language and literacy instruction in classrooms was low, with few teachers delivering high quality instruction. Although teachers were able to implement a prescribed language and literacy curriculum with a high degree of procedural fidelity, this was not associated with quality instruction. Few structural characteristics of classrooms of teachers were systematically associated with quality of instruction. Findings have important implications for professional development of teachers by suggesting a need for a sustained and coherent focus on the process of instruction to elevate instructional quality in language and literacy.     

Effects of web-mediated professional development resources on teacher–child interactions in pre-kindergarten classrooms

As the workforce in state-funded pre-kindergarten programs continues to grow in the United States, the promise of these and other early education opportunities (e.g., Head Start) depends in large part on in-service professional development and training in key instructional and interaction skills. In this paper, we describe effects of MyTeachingPartner (MTP), a web-based system of professional development resources, that include video exemplars and web-mediated consultation on specific dimensions of interactions with children for 113 teachers in a state-funded pre-k program. Teachers assigned to receive on-line consultation and feedback targeted to their interactions showed significantly greater increases in independent ratings of the quality of interactions than did those only receiving access to a website with video clips. The positive effects of consultation were particularly evident in classrooms with higher proportions of children who experienced economic risks. Implications of these findings for models of professional development and widespread needs for teacher access and support are discussed in relation to the effectiveness of early education.     

Measures of classroom quality in prekindergarten and children's development of academic, language, and social skills

This study examined development of academic, language, and social skills among 4-year-olds in publicly supported prekindergarten (pre-K) programs in relation to 3 methods of measuring pre-K quality, which are as follows: (a) adherence to 9 standards of quality related to program infrastructure and design, (b) observations of the overall quality of classroom environments, and (c) observations of teachers' emotional and instructional interactions with children in classrooms. Participants were 2,439 children enrolled in 671 pre-K classrooms in 11 states. Adjusting for prior skill levels, child and family characteristics, program characteristics, and state, teachers' instructional interactions predicted academic and language skills and teachers' emotional interactions predicted teacher-reported social skills. Findings suggest that policies, program development, and professional development efforts that improve teacher–child interactions can facilitate children's school readiness.     

Internalizing and externalizing in adolescence: the roles of academic self‐efficacy and gender

This study examines academic self‐efficacy and gender as predictors of internalizing and externalizing behaviors in adolescence. In addition, the role of gender was considered as a moderator in the relationship between academic self‐efficacy and internalizing/externalizing difficulties. Participants were 4,318 predominantly African American, low‐income high school students who completed self‐report measures on the constructs of interest. Academic self‐efficacy and gender were both significant predictors of risk for internalizing problems, whereas only academic self‐efficacy predicted risk for externalizing (hyperactivity/distractibility) problems. Gender did not predict externalizing difficulties, nor did gender serve as a moderator in any analysis. Implications include focusing on academic self‐efficacy in the development of strategies for prevention and intervention of internalizing and externalizing problems.     

Validity of Wrist-Worn photoplethysmography devices to measure heart rate: A systematic review and meta-analysis

ABSTRACT

Heart rate (HR), when combined with accelerometry, can dramatically improve estimates of energy expenditure and sleep. Advancements in technology, via the development and introduction of small, low-cost photoplethysmography devices embedded within wrist-worn consumer wearables, have made the collection of heart rate (HR) under free-living conditions more feasible. This systematic review and meta-analysis compared the validity of wrist-worn HR estimates to a criterion measure of HR (electrocardiography ECG or chest strap). Searches of PubMed/Medline, Web of Science, EBSCOhost, PsycINFO, and EMBASE resulted in a total of 44 articles representing 738 effect sizes across 15 different brands. Multi-level random effects meta-analyses resulted in a small mean difference (beats per min, bpm) of ?0.40 bpm (95 confidence interval (CI) ?1.64 to 0.83) during sleep, ?0.01 bpm (?0.02 to 0.00) during rest, ?0.51 bpm (?1.60 to 0.58) during treadmill activities (walking to running), while the mean difference was larger during resistance training (?7.26 bpm, ?10.46 to ?4.07) and cycling (?4.55 bpm, ?7.24 to ?1.87). Mean difference increased by 3 bpm (2.5 to 3.5) per 10 bpm increase of HR for resistance training. Wrist-worn devices that measure HR demonstrate acceptable validity compared to a criterion measure of HR for most common activities.     

Cognitive validity of students’ self-reports of classroom mastery goal structure: What students are thinking and why it matters

Cognitive interviews were employed to systematically examine the cognitive validity of self-report survey items extensively used to assess classroom mastery goal structure. In a sample of elementary and middle school students, items were identified that functioned according to their intended meaning and those eliciting less accurate interpretations as conceptually defined by mastery goal structure cognitive validity criteria. Evidence suggested that items framed to focus on students’ teachers (i.e., teacher goals) were more cognitively valid than were items that focused students on their classroom context. Items with abstract terms yielded less accurate interpretations. We discuss implications of determining the cognitive validity of scales used to assess achievement goal structure and related self-report instruments.     

Protection from extinction provided by a conditioned inhibitor

Three conditioned suppression experiments with rats as subjects investigated the influence of higher order associations in determining the response potential of a target stimulus. In these experiments, a Pavlovian conditioned inhibitor was compounded with the target cue during extinction treatment. In Experiment 1, strong suppression was observed to the target cue that was given extinction treatment in the presence of a conditioned inhibitor, relative to a target that was extinguished with an associatively neutral cue or was extinguished alone, suggestive of enhanced protection from extinction provided by a conditioned inhibitor. This effect was replicated in a sensory preconditioning preparation in Experiment 2; in Experiment 3, in a sensory preconditioning preparation, this protection effect was retroactively attenuated when the conditioned excitor used to train the conditioned inhibitor was extinguished following extinction of the target. This provides evidence that, at least in a sensory preconditioning preparation, stimuli that are only indirectly associated with the target cue can contribute to the response potential of that target.     

A three-phase examination of academic comparative optimism and perceived academic control

Early academic perceptions are critical to undergraduate students' success in college. This 3-phase study examined stability of and links between academic comparative optimism (ACO; positive expectations about future performance) and perceived academic control (PAC; sense of influence over academic outcomes) among 68 undergraduate students. ACO and PAC were assessed at the start, midway through, and at the end of a semester and a cross-lagged panel analysis tested which academic perception better predicted the other. We also examined early ACO and PAC as predictors of later achievement. Students' ACO and PAC were fairly stable throughout the semester. Regression analyses (controlling for course load, prior achievement, and prior ACO or PAC) indicated ACO predicted PAC more so than the reverse, suggesting students may boost their PAC via optimistic social comparisons. Early ACO predicted later performance. Implications for enhancing ACO and PAC early in the academic year are discussed.
