Positive Affectivity and Fear Trajectories in Infancy: Contributions of Mother–Child Interaction Factors

Fear and positive emotionality were considered in a growth modeling context. Mothers, primarily Caucasian (91.9%) and of middle socioeconomic status, participated in play interactions with infants at 4 months (N = 148). Infant fear and positive affectivity were evaluated at 6, 8, 10, and 12 months of age. A linear trajectory was superior in explaining growth for parent report and observation‐based indicators of positive affectivity and parent report of fearfulness; a piecewise model explained the nonlinear growth of observation‐based fear. Responsiveness in mother–infant interactions emerged as a significant predictor of the fear trajectory, with higher sensitivity predicting lower levels of observed fear. Reciprocity, tempo, emotional tone, and intensity of mother–infant interactions also made significant contributions to temperament development; however, analyses addressing these were exploratory.     

‘Whoops,I forgot David’: children's perceptions of the adults who work in their classrooms

This article reports on the findings of a small‐scale study into the perceptions of 78 primary school children regarding the adults in their classrooms. The data show that children easily differentiate between their own class teacher and other adults, but report a substantial overlap between the activities of teachers and teaching assistants. Some express the difference in terms of status rather than role. Accounts call into question the notion that teaching assistants ‘help’ rather than teach and that there is a clear division of labour between them and teachers. Teachers and assistants are seen as working in an interdependent way, with each making a significant contribution to children's learning. The difficulties of using children's language as evidence are considered and it is concluded that the notion of a ‘remodelled’ primary school workforce needs to take into account the ways in which teachers and assistants maintain fluid working relationships.     

Oh No! They Cut My Funding! Using “Post Hoc” Planned Missing Data Designs to Salvage Longitudinal Research

Having one’s funding cut in the course of conducting a longitudinal study has become an increasingly real challenge faced by developmental researchers. The main purpose of the current work is to propose “post hoc” planned missing (PHPM) data designs as a promising solution in such difficult situations. This study discusses general guidelines that can be followed to search for viable PHPM designs within a given budget restriction. Illustrative examples across different longitudinal research contexts are provided, each showing how PHPM data designs can help salvage longitudinal studies when an unexpected funding cut occurs mid-study. With the illustrative examples, the article also shows how developmental researchers can conveniently identify viable designs using the R package simPM .     

Enhancing Early Childhood Development Through Arts Integration in Economically Disadvantaged Learning Environments

Education in the arts continues to struggle for inclusion in PreK-12 classrooms as public schools face increasing challenges from high stakes testing, Common Core politics, and endless budget cuts. Advocates point to the growing body of research linking art education to academic achievement as justification for arts’ continued inclusion in the curriculum. In its 2005 report, the National Association of State Boards of Education highlighted this research trend and called for stronger emphasis on arts in educational curricula (Meyer in Arts Educ Policy Rev 106(3):35–40, 2005). Yet despite the evidence, school districts across the nation have been slow to include more arts programming within the classroom. This study, however, examines one school district that did. In a collaborative project between a large urban school district and a local arts and science council, an arts integration program called Wolf Trap was implemented in economically disadvantaged pre-Kindergarten and first-grade classrooms at selected schools across the district. Objectives of the program were to: (a) improve school readiness skills among participants; (b) increase capacity of classroom teachers to learn and implement effective arts-based teaching strategies; and (c) increase the capacity of teaching artists to acquire and model effective arts-based teaching strategies. This study evaluates the effectiveness of the program using data from the teaching artists, classroom teachers, and the external evaluators. We discuss the program in detail and explain the methodology used in our evaluation. Finally, we present evidence that indicates the program’s success and we offer recommendations for program stakeholders.

Mental and Psychomotor Task Performance in an Open Ocean Underwater Environment

Abstract

A form for student evaluation of instructional effectiveness was developed and evaluated. The form included two sections: (1) an 18-item section designed to evaluate each of six dimensions of instruction, and (2) an 8-item section designed to assess course outcomes. Analysis of 1382 completed forms from 66 sections of 25 different types of lifetime sports classes demonstrated: (1) alpha coefficients of five of the six scales representing the dimensions of instruction ranged from .68 to .83; (2) ratings on instructional methods were predictive of satisfaction with the instructor and course, but none were predictive of progress toward course objectives (participation, competence and attitude); and (3) enthusiasm for the subject matter, and sensitivity to class progress were most predictive of course outcomes. Followup questionnaires from students who had been enrolled in highly rated classes yielded significantly higher scores on participation and teaching activity levels as well as satisfaction with the course and instructor than questionnaires from those who had been enrolled in low rated classes. Potential for elimination of items to develop a shorter survey form was explored.     

Coach Selections and the Relative Age Effect in Male Youth Ice Hockey

Relative age effects (RAEs; when relatively older children possess participation and performance advantages over relatively younger children) are frequent in male team sports. One possible explanation is that coaches select players based on physical attributes, which are more likely witnessed in relatively older athletes. Purpose: To determine if coach selections are responsible for RAEs by comparing RAEs in male players who played competitive versus noncompetitive ice hockey. Method: Using chi-square, we analyzed the birth dates of 147,991 male ice hockey players who were 5 to 17 years old. Players' birth dates were divided into four quartiles, beginning with January to March, which coincides with Hockey Canada's selection year. Results: There were strong RAEs (p < .001) when players were selected to competitive teams by coaches through a tryout system. On noncompetitive teams that did not have coach selections, there were strong RAEs (p < .001) from 5 to 8 years old, but not 9 to 17 years old. Conclusions: Although coaches might perpetuate RAEs, other influential social agents might include parents, which ought to be investigated in future research.
