Exploration of the Relative Contributions of Domain Knowledge and Search Expertise for Conducting Internet Searches

The relative contributions of expertise in search skills and domain knowledge were examined when using the Internet to find information. Four conditions were compared: expert searchers/high domain knowledge; expert searchers/low domain knowledge; novice searchers/high domain knowledge; and novice searchers/low domain knowledge. Search outcomes and verbal protocols were analyzed. The combination of search expertise and high domain knowledge yielded the most efficient searches. Higher search expertise yielded access to sites rated more accurate and credible. High domain knowledge yielded sites rated more thorough. Verbal protocols depicted searching as a complex decision process. Findings have implications for instructional support.     

Special and inclusive education in the Republic of Ireland: reviewing the literature from 2000 to 2009

Provision for pupils with special educational needs in Ireland has undergone considerable change and review in the first decade of the twenty‐first century. In response to international demands for a more equitable education system that recognises diversity and considers how schools might address the needs of pupils who have been previously marginalised, Irish legislation has focused upon the development of inclusive schooling. Researchers during this period have endeavoured to understand how responses to the demand for greater inclusion have impacted upon the perceived need for change. This paper reviews the research literature for this period and identifies four key themes under which research has been conducted. The literature pertaining to these themes is explored and a possible agenda for future researchers identified.     

Peer-Instruction-哈佛大学物理课程教学新方法

Peer-Instruction教学方法是哈佛大学著名教授Eric Mazur创立,使用专门设计的用于揭示学生错误概念和引导学生深入探究的概念测试题(ConcepTests),借助计算机投票系统(Computerized Voting System),组织大班课堂教学,变传统单一的讲授为基于问题的自主学习和协作探究,有效地改变了传统课堂教学手段、教学模式.在大班课堂教学中实现学生自主学习、合作学习、师生互动、生生互动.本文旨在介绍这种教学方法,阐明其教育意义和促进学生学习方面的作用,综述了PI教学方法的广泛应用和相关研究结果.     

Using literature and innovative assessments to ignite interest and cultivate critical thinking skills in an undergraduate neuroscience course

Science education reform initiatives emphasize 1) the value of concepts over facts; 2) the benefits of open-ended, inquiry-based problem-solving rather than protocols leading to a single correct answer; and 3) the importance of a multidisciplinary approach to teaching that is not confined by departmental boundaries. Neuroscientists should be at the forefront of this movement by the very nature of the discipline we study. Neuroscience is a relatively new field that integrates diverse subjects (anatomy, physiology, pharmacology, molecular biology, computer science, and psychology) and experimental advances are constantly changing and expanding our understanding of brain function. How can we convey this excitement in the classroom? The project described in this article uses nonscientific literature to introduce a scientific topic of study. In addition, the multitask assignment requires the acquisition of content knowledge and the development of critical thinking skills. As students explore the topic from multiple perspectives, they recognize the interconnectedness of science and society and confront ethical and moral issues related to science. A comparison of exam scores, essay responses, engagement level, as well as students' own reflections, demonstrates that inclusion of the project does not sacrifice content knowledge, rather it enhances the overall learning process.     

Past experience,recency, and spontaneous recovery in choice behavior

Pigeons’ responses on two keys were recorded before and after the percentage of reinforcers delivered by each key was changed. In each condition of Experiment 1, the reinforcement percentage for one key was 50% for several sessions, then either 70% or 90% for one, two, or three sessions, and then 50% for another few sessions. At the start of the second and third sessions after a change in reinforcement percentages, choice percentages often exhibited spontaneous recovery—a reversion to the response percentages of earlier sessions. The spontaneous recovery consisted of a shift toward a more extreme response percentage in some cases and toward a less extreme response percentage in other cases, depending on what reinforcement percentages were previously in effect. In Experiment 2, some conditions included a 3-day rest period before a change in reinforcement percentages, and other conditions included no such rest days. Slightly less spontaneous recovery was observed in conditions with the rest periods, suggesting that the influence of prior sessions diminished with the passage of time. The results are consistent with the view that choice behavior at the start of a new session is based on a weighted average of the events of the past several sessions.     

The Evidence Base for Mental Health Consultation in Early Childhood Settings: A Research Synthesis Addressing Children's Behavioral Outcomes

Research Findings: Early childhood mental health consultation aims to reduce problem behaviors and improve social skills in young children primarily through changes in the classroom environment and teacher practices. We conducted a systematic review of the literature and identified 14 rigorous studies that reported on child-level outcomes. These studies had at least one of the following characteristics: publication in a peer-reviewed journal, use of a randomized control trial design, or inclusion of a comparison group. Across these studies, there was variation in the approaches to consultation, qualifications of the consultants, and intensity of the services provided. Overall, early childhood mental health consultation services were consistently associated with reductions in teacher-reported externalizing behaviors. Findings related to reductions in internalizing behaviors were mixed. Teacher ratings of prosocial behaviors were improved in the majority of the studies that reported on this domain. Practice or Policy: This research synthesis underscores the importance of documenting the specific approaches to early childhood mental health consultation that are being implemented to allow for replication of effective models. Areas for future research improvement include increasing rigor through studies that contain independent assessments of children's behaviors, isolating key components of effective consultation, and identifying consultant qualifications and characteristics that lead to child behavior changes.
