Heart Rate and Behavioral measures of Attention in Six-, Nine-, and Twelve-Month-Old Infants during Object Exploration

In this study we examined the effect of heart rate and behavioral measures of attention on distractibility of 6-, 9-, and 12-month-old infants. The infants were presented with a toy, and a distractor was presented while they attended to the toy. The distractor was presented during heart rate changes indicating sustained attention or attention termination, or during periods of time when behavioral ratings indicated the infant was in focused or casual attention. There were longer distraction latencies during attentional engagement as defined by heart rate changes or behavioral ratings than for periods of inattention. Infants had the longest distraction latencies when heart rate and behavior measures were congruent with respect to attention engagement (heart rate deceleration and focused attention). Conversely, latencies were shortes for congruent values of inattention (heart rate acceleration and casual attention). Infant information processing may be greatest when a heart rate deceleration occurs simultaneously with an episode of focused attention.     

A VBA‐based Simulation for Teaching Simple Linear Regression

In spite of the name, simple linear regression presents a number of conceptual difficulties, particularly for introductory students. This article describes a simulation tool that provides a hands‐on method for illuminating the relationship between parameters and sample statistics.     

The Lamer Social Competence in Preschool (LSCIP) Scale: Structural Validity in a Large Norwegian Community Sample

There is an increasing emphasis on the importance of social competence for children's development, well-being, and learning. Thus age- and context-appropriate measures are needed. This study addresses the structural validity of the Lamer Social Competence in Preschool (LSCIP) scale, developed to accommodate the Nordic model of early childhood pedagogy. The authors specify the theoretical basis for a bi-factor model of social competence. This model is tested in a large (n?=?1157), community based sample of Norwegian children, including teacher- (at age 2, 3, and 4), mother- (at age 4), and father- (at age 3) reports. A model with a main factor for social competence, and three bi-factors fit data across ages and reporters, with factorial, but not strong, invariance over time.     

Inhibitory control by one stimulus after an increase in the frequency of reinforcement associated with another stimulus

Pigeons were trained on a multiple variable-interval 5-min variable-interval 5-min schedule and then shifted to either a multiple variable-interval 1-min variable-interval 5-min or a multiple variable-interval 30-sec variable-interval 5-min schedule. A generalization test was subsequently administered along the dimension containing the stimulus associated with the variable-interval 5-min component. The generalization gradients for subjects that received multiple variable-interval 1-min variable-interval 5-min training were not consistent in shape. However, an incremental gradient was obtained from each subject that received multiple variable-interval 30-sec variable-interval 5-min training. Thus, a sufficiently large reduction in merely the relative frequency of reinforcement during a stimulus resulted in that stimulus’ acquiring inhibitory control over responding.     

Reclaiming Teacher Agency in a Student-Centred Digital World

This article examines the current dilemma faced by many teachers: the drive for a modern day pedagogy advocating student-centred, technology-enabled learning is at odds with teacher comfort zones still nestled in a teacher-talk, print-based classroom. Put another way, the 'techno-reluctance' of many teachers represents a negative reaction to the perception that new technologies represent a threat to their traditional roles and general sense of practical agency in the learning process or classroom. The paper interprets some of the key factors impacting on techno-reluctance as a means of moving beyond such a simplistic view of the connection between digital technologies and changing teacher roles. On this basis, it goes on to discuss the concept of 'technoliteracy' as a means of reclaiming teacher agency in a studentcentred, computer-mediated environment and also reframing teacher attitudes to electronic texts and related literacy practices.     

The Severity of State Truancy Policies and Chronic Absenteeism

ABSTRACT

Since the Common School era, states have maintained truancy laws to ensure that students attend school. However, we know little about the severity of these laws and their relationship to student outcomes, particularly absenteeism. In this study, we survey state education statutes to document the severity of truancy policies. We estimate the relationship between these truancy policies and rates of chronic absenteeism via multilevel models using data on all U.S. public schools from the Office of Civil Rights. We find that most students live in states where they may be referred to legal authorities for levels of absenteeism below federal standards. We find little evidence that states with truancy policies have lower chronic absenteeism after adjusting for demographic and other characteristics. However, while non-White high-school students are overrepresented among chronic absences overall, they have rates of chronic absenteeism comparable to their White peers in states with less severe truancy policies.     

Addressing Physical Education Teacher Socialization Through Standards-based Reform of Physical Education Teacher Education

Research suggests that progress in the physical education profession is slowed by a cycle of nonteaching and dominance of traditional methodologies. Socialization factors operate to preserve and perpetuate the status quo of the profession, which is rooted primarily in team sport content. Teacher education programs are challenged to persuade pre-service teachers to question their initial belief structures while also preparing them for the sociopolitical realities of schools. There is not, however, a formal mechanism through which to accomplish these goals, because current accreditation standards do not include an emphasis on socialization. As a result, the purpose of this article is to stimulate further discussion by reviewing relevant research related to socialization, describe evidence-based practices for overcoming these challenges, and propose an addition to the Society of Health and Physical Educators America (2017) standards for initial physical education teacher education to specifically focus attention on socialization issues.     

Argument and Authority in the Visual Representations of Science

The focus of workplace communication research on visual rhetoric has tended to be the efficient and unproblematically “effective” functioning of visual texts. By suggesting ways in which the visual representations of science are construed by expert readers, this article responds to a call within our discipline for more critically focused contributions to the study of visual literacy. A former editor-in-chief of the American Journal of Botany was asked to explain his interpretation of visuals appearing over an 80-year period in that journal; his responses illustrate how visual explanations testify to their creators' authority and how, once established, such authority actuates the rational arguments of science. Rhetorical appeals within and arrangement of visual texts are considered, as is the persuasive power of legends and captions.
