Systematic errors are often unavoidable in the introductory physics laboratory. As has been demonstrated in many papers in this journal, such errors can present a fundamental problem for data analysis, particularly when comparing the data to a given model. In this paper I give three examples in which my students use popular curve-fitting software…

This paper outlines the use of "how to" videos, in the form of a screencast using a tablet computer, and posting the videos online. These videos are useful for when students miss a class, for those students who need to review a lesson or examples used in class when doing homework or reviewing for a test, for instructors of online classes, and also…

This article examines the connection between ACRL information literacy standards and constructivist pedagogy. This connection is used to support use of Web 2.0 tools for information literacy instruction. Sample exercises using these tools are provided for each ACRL learning outcome, and the tools' suitability for the constructivist approach is…

Have you ever put your hand on an electric motor or motor-driven electric appliance and felt it vibrate? Ever wonder why it vibrates? What is there about the operation of the motor, or the object to which it is attached, that causes the vibrations? Is there anything "regular" about the vibrations, or are they the result of random causes? In this…

This paper presents an introductory signal processing laboratory and examines this laboratory exercise in the context of problem-based learning (PBL). Centered in a real-world application, a cochlear implant, the exercise challenged students to demonstrate a working software-based signal processor. Partnering in groups of two or three, second-year…

These days, school district budgets are getting hit on both sides: State budgets are facing drastic cuts across the United States at the same time that many schools are dealing with rising insurance premiums and retirement fund payouts. It's no wonder that technology is often an early casualty in district fiscal planning. Unfortunately, in this…

Purpose: The prevalence of virtual learning environments (VLEs) in higher education is well documented and has been promoted in the UK by government funded projects, but there has been little empirical research on the level of involvement of subject librarians with VLEs. A survey was designed to investigate how VLEs are affecting the work of…

This commentary reviews seven papers that study motivation with new media, contained in this special issue of "Educational Technology Research & Development" edited by Ruth Small. For each paper, this commentary summarizes exemplary contributions, offers an assessment of what is exciting, and suggests directions for future research. Some exciting…

For individuals with autism spectrum disorders (ASD), the use of technology to provide intervention, particularly targeting the core social-communication deficits of the disorder, is promising. This literature review will examine studies that have used innovative technology, such as interactive computer programs and virtual reality, to deliver…

This study investigated the online reading performances and the level of visual fatigue from the perspectives of non-native speaking students (NNSs). Reading on a computer screen is more visually more demanding than reading printed text. Online reading requires frequent saccadic eye movements and imposes continuous focusing and alignment demand.…

Learning Management Systems (LMS) are being integrated in the curriculum by many educational institutions to extend teaching and learning beyond classroom. This paper is based on a case study exploring the integration of LMS Nalanda created on Moodle in Effective Public Speaking (EPS) classroom to give students an additional platform to practice,…

A small group of high school students performed a virtual laboratory experiment in Second Life that mimicked a real experiment in both its appearance and procedure. Lab report grades were equivalent to report grades for hands-on experiments, and the quality of students' results was similar. Results of an attitudinal survey show that students…

This study used quantitative analyses complemented by the retrospective data obtained through a stimulated recall procedure to address three interrelated issues: (a) whether second language learners use online planning opportunities to carefully plan their speech to enhance the quality of the language they produce, (b) what kinds of self-repair…

This report is a collaborative research effort between the New Media Consortium (NMC), Concordia International School Shanghai, and NIST International School in Bangkok, Thailand, to help inform international school leaders in Asia about significant developments in technologies supporting teaching, learning, and creative inquiry in primary and…

In this paper, we describe the development and evaluation of a microworld-based learning environment for neuroscience. Our system, BrainExplorer, allows students to discover the way neural pathways work by interacting with a tangible user interface. By severing and reconfiguring connections, users can observe how the visual field is impaired and,…
