Children's Use of Converging Obliques in their Perspective Drawings

This paper investigates children's use of converging obliques in their drawings of objects. Adults and adolescents, as well as 7‐year‐old children, were not very successful in using converging obliques in their drawings of small‐scale objects; they tended to use parallel edges. When confronted with the apparent convergence of a real road receding into the distance adults and adolescents switched to using converging obliques; 7‐year‐olds still drew parallel roadsides. Children were induced to use converging obliques, however, when asked to copy from a line drawing of a road or from a photograph, particularly when the convergence of the road in the photograph was more dramatic.     

Young Children's Ability to Adapt their Drawings of the Human Figure

5‐year‐olds, 7‐year‐olds and 9‐year‐olds were asked to draw three figures, one standing still and facing them, one standing still in profile and one running in profile. Half drew from imagination and half drew from models. The 5‐year‐olds made fewest distinctions in the way they drew the figures, the most notable being the greater spread of the legs of the running figure. With increasing age, more features were used to differentiate the three figures. There was little evidence of 5‐year‐olds adapting their figures in the presence of a model. Only among the older children was there a significant effect of the presence of a model when the 7‐year‐olds and, to a greater extent, the 9‐year‐olds drew their running figure with bent arms and legs and also with more transparencies and partial occlusions.     

Distributed Cognition in Sports Teams: Explaining successful and expert performance

Abstract

In this article we use a hybrid methodology to better understand the skilful performance of sports teams as an exemplar of distributed cognition. We highlight key differences between a team of individual experts (an aggregate system) and an expert team (an emergent system), and outline the kinds of shared characteristics likely to be found in an expert team. We focus on the way that shared knowledge contributes to expert team performance. In particular, we suggest that certain kinds of shared knowledge (both embodied and declarative) and shared skill, potentially developed through a team’s history of playing and training together, facilitate successful coordination. These kinds of shared knowledge and skill may be less developed in a team of experts without a shared history. Exploring the expert performance of sports teams informs our understanding of distributed cognition and collaboration more generally and creates avenues for further philosophical and empirical investigation.     

Organizational Surveys: A System for Employee Voice

Although surveys are often used to assess and track employee attitudes and opinions over time and are used quite frequently by applied communication researchers, the use of surveys as a channel to voice employee attitudes and opinions has not been fully explored in the employee voice or basic organizational communication literature. With the increased call for accountability, effective applied communication researchers can play an important role in ensuring that organizations engage in the survey process in a manner that is “safe” for employees, and ethical and practical for the organization. Because the question of how to accomplish this task is complex and cannot be fully addressed within the constraints of a commentary, I offer three general principles to guide future researchers in helping overcome organizational communication problems:

1. Build trust in the organizational survey process, the researcher(s), and the organization.

2. Eliminate the adversarial relationship that often exists between management and employees who speak up.

3. Provide evidence that the organization does more than purport to value the things that it says it values.

     

Fast-Paced,Romantic, Set in Savannah: A Comparison of Results from Readers' Advisory Databases in the Public Library

Readers' advisory databases are used by public librarians to assist patrons in finding books based on the facts of the plot, the factors used to describe the appeal of the book, or read titles similar to another book they have read. Librarians depend on these databases to give a complete view of the titles available given these limiters, and may assume that identical searches in each database would give similar results. This study compares search results from four databases to see the extent of crossover within those results, using fact-based searches, appeal factor searches, and read-alike searches.     

Coordinating principles and examples through analogy and self-explanation

Research on expertise suggests that a critical aspect of expert understanding is knowledge of the relations between domain principles and problem features. We investigated two instructional pathways hypothesized to facilitate students’ learning of these relations when studying worked examples. The first path is through self-explaining how worked examples instantiate domain principles and the second is through analogical comparison of worked examples. We compared both of these pathways to a third instructional path where students read worked examples and solved practice problems. Students in an introductory physics class were randomly assigned to one of three worked example conditions (reading, self-explanation, or analogy) when learning about rotational kinematics and then completed a set of problem solving and conceptual tests that measured near, intermediate, and far transfer. Students in the reading and self-explanation groups performed better than the analogy group on near transfer problems solved during the learning activities. However, this problem solving advantage was short lived as all three groups performed similarly on two intermediate transfer problems given at test. On the far transfer test, the self-explanation and analogy groups performed better than the reading group. These results are consistent with the idea that self-explanation and analogical comparison can facilitate conceptual learning without decrements to problem solving skills relative to a more traditional type of instruction in a classroom setting.     

An Ethical Exercise for the Social Studies Classroom: The Trolley Dilemma

The Trolley Problem as defined in this paper is a series, or continuation, of increasingly difficult ethical riddles successfully implemented in a classroom environment to spur complex, critical thinking and dialogue. The activity is designed upon the scenario of a runaway train with different and challenging choices, segueing neatly into group discussions of ethics while limiting potential disruptions or controversies. It fits nicely with multiple standards, goals and/or outcomes and can be accommodated to multiple grade levels and courses. It is a powerful, yet easily implemented classroom exercise for educators to develop higher order thinking and dialogue for their students.
