In the study of kinematics it is often emphasized that freefall time is independent of particular parabolic trajectory, provided that the initial velocity is parallel to the horizontal plane. There are various experiments to prove features of freefall in textbooks and other literature. Using a PC one can make precise measurements of time intervals…

HomeworkNYC Apps is a suite of tools designed to provide around-the-clock help to the estimated 1.3 million children and teens served by the libraries of New York City. Aimed at being a one-stop shop for all things homework related, the HomeworkNYC website offers access to library catalogs and databases, browsable subject guides, and even…

A search of the ERIC and Academic Search Premier data bases, and a comprehensive review of literature suggest that meta-analysis is ignored by career and technical education (CTE) researchers, a situation that is regrettable but remediable. The purpose of this theoretical paper is to provide CTE researchers and consumers with procedures for…

Open education, as embodied in open educational resources (OER) and OpenCourseWare (OCW), has met and dealt with several key problems. The movement now has a critical mass of available content. Leveraging no small amount of funding and associated development, open education has the tools to collect, disseminate, and support the discovery of open…

Self-regulated learning (SRL) with hypermedia environments involves a complex cycle of temporally unfolding cognitive and metacognitive processes that impact students' learning. We present several methodological issues related to treating SRL as an event and strengths and challenges of using online trace methodologies to detect, trace, model, and…

GENIQUEST is a cyberlearning computer program that allows students to investigate biological data using a research-based instructional model. In this article, the authors make the case for using cyberlearning to teach students about the rapidly growing fields of genomics and computational biology. (Contains 2 figures and 1 online resource.)

We use the computing technology digital image processing (DIP) to enhance the teaching of linear algebra so as to make the course more visual and interesting. Certainly, this visual approach by using technology to link linear algebra to DIP is interesting and unexpected to both students as well as many faculty. (Contains 2 tables and 11 figures.)

Collaborative learning must prompt collaborative behavior among students. Once initiated, collaboration then must facilitate awareness between students of each other's activities and knowledge. Collaborative scripts provide explicit framework and guidance for roles and activities within student interactions, and are one method of fulfilling the…

This article urges counseling psychology researchers to recognize and report how missing data are handled, because consumers of research cannot accurately interpret findings without knowing the amount and pattern of missing data or the strategies that were used to handle those data. Patterns of missing data are reviewed, and some of the common…

Understanding what hybrid space is, much less understanding what happens in that virtual realm, can raise difficult questions. For example, our campus's question "How do we define hybrid?" has kept us busy and guessing for over a year now. In this article, we offer a few suggestions on how to proceed with hybrid issues, including how to deal with…

We performed experiments in which a soccer ball was launched from a machine while two high-speed cameras recorded portions of the trajectory. Using the trajectory data and published drag coefficients, we extracted lift coefficients for a soccer ball. We determined lift coefficients for a wide range of spin parameters, including several spin…

Two methods of data analysis are compared: spreadsheet software and a statistics software suite. Their use is compared analysing data collected in three selected experiments taken from an introductory physics laboratory, which include a linear dependence, a nonlinear dependence and a histogram. The merits of each method are compared. (Contains 7…

Schools fear the predatory behavior that lurks around social networking sites, where the exchange of personal information can make users sitting ducks for hackers, thieves, cyberbullies, and scammers. So they're caught in what appears to be an all-or-nothing choice: take advantage of the academic opportunities that social networking sites can…

The main research object of the paper is investigation and proposal of the comprehensive Learning Object Repositories (LORs) quality evaluation tool suitable for their multiple criteria decision analysis, evaluation and optimisation. Both LORs "internal quality" and "quality in use" evaluation (decision making) criteria are analysed in the paper.…

In a time of budget cuts and limited funding, purchasing and installing the latest software on classroom computers can be prohibitive for schools. Many educators are unaware that a variety of free software options exist, and some of them do not actually require installing software on the user's computer. One such option is cloud computing. This…
