Teaching Confidence Intervals Using Simulation

Confidence intervals are difficult to teach, in part because most students appear to believe they understand how to interpret them intuitively. They rarely do. To help them abandon their misconception and achieve understanding, we have developed a simulation tool that encourages experimentation with multiple confidence intervals derived from the same population.     

10,000 Libraries, 4 Years: A Large-Scale Study of E-Book Usage and How You Can Use the Data to Move Forward

Michael Levine-Clark and Kari Paulson examine 2013 worldwide usage data for ebrary and E-book Library (EBL) covering hundreds of thousands of titles. They examine usage patterns across academic libraries globally and establish benchmarks useful to libraries and consortia for local planning. Sessions versus availability, the use of higher-quality e-books, broad disciplinary differences, performance relative to predicted use, and level of immersion are considered. Levine-Clark is in the process of analyzing ebrary and EBL data for a forthcoming white paper, and this presentation and associated discussion will inform the development of that study.     

Exploring the Potential of Computers to Enrich Home and Community-Based Services Clients' Social Networks

Older persons receiving services in community settings, rather than Nursing Homes, are at risk of social isolation. Computer mediated communication offers technological resources that recipients of Home and Community-Based Services (HCBS) might use to reduce their social isolation. The present study involved personal interviews with 40 HCBS clients regarding their interest in communicating with members of their social networks and using computers. At the time of the interview, 30 of the 40 participants did not use computers and reported cost, lack of training, physical limitations, lack of interest and access, and fraud as the reasons for not using computers. After watching a videotape illustrating an easy-to-use computer interface that allows older persons to communicate with families and friends, 90% reported that it would be helpful for people like them. Participants said such a computer would be helpful because it would make communication with friends and family easy, it could accommodate visual and manual disabilities, and would be interesting. Eighty-five percent said they would use a system like the one they were shown if it were available to them.     

Preservice and Inservice Teachers’ Challenges in the Planning of Practical Work in Physics

Practical work in school science plays many essential roles that have been discussed in the literature. However, less attention has been paid to how teachers learn the different roles of practical work and to the kind of challenges they face in their learning during laboratory courses designed for teachers. In the present study we applied the principles of grounded theory to frame a set of factors that seem to set major challenges concerning both successful work in the school physics laboratory and also in the preparation of lessons that exploit practical work. The subject groups of the study were preservice and inservice physics teachers who participated in a school laboratory course. Our results derived from a detailed analysis of tutoring discussions between the instructor and the participants in the course, which revealed that the challenges in practical or laboratory work consisted of the limitations of the laboratory facilities, an insufficient knowledge of physics, problems in understanding instructional approaches, and the general organization of practical work. Based on these findings, we present our recommendations on the preparation of preservice and inservice teachers for the more effective use of practical work in school science and in school physics.     

Children in nature: sensory engagement and the experience of biodiversity

Given concerns for a severely diminished childhood experience of nature, coupled with alarm for a rapidly diminishing global biodiversity, this article considers the potential for childhood nature experience to be an important part of biodiversity understanding. Findings from two studies are integrated and presented as windows into childhood nature experience to illuminate important aspects of sensory rich learning. In one study from Sweden, semi-structured interviews with adults were conducted and analyzed to explore an understanding of the sensory experience of childhood collecting in nature via participant memories. In the second study, direct observations of children’s play and exploration in an outdoor kindergarten in Norway were conducted and analyzed. Bringing these two studies together for shared analysis is useful for investigating biodiversity experience and understanding. Analysis supports the idea that the experience of biodiversity, actual childhood interaction with variation and diversity with living and nonliving items from nature allows children important learning opportunities, inclusive of biodiversity understanding. The results support practical implications for sensory rich environmental education and underscores the practical importance of childhood access to nature.     

School psychologists and autism identification: Present challenges and potential solutions

Although federal law has provided guidelines for autism eligibility for special education, school-based autism assessment and eligibility vary widely across states and identification continues to lag behind national prevalence data. The main role of the school psychologist continues to be conducting evaluations for special education eligibility, and given current barriers, some school psychologists do not feel equipped to make a recommendation for autism eligibility. This article summarizes the barriers school psychologists face when conducting autism assessments in the schools, including systemic barriers, lack of training or professional development, resulting lack of confidence, among others. We conclude by highlighting recommendations for multipronged systemic changes that will improve the capacity of special education teams and specifically support the pivotal role of the school psychologist in conducting autism eligibility evaluations in the schools.
