This physical chemistry lecture demonstration is designed to aid the understanding of intramolecular energy transfer processes as part of the presentation of the theory of unimolecular reaction rates. Coupled pendulums are used to show the rate of migration of energy between oscillators under resonant and nonresonant conditions with varying…

The click chemistry uses only the most reliable reactions to build complex molecules from olefins, electrophiles and heteroatom linkers. A variation on Huisgen's azide-alkyne 1,2,3-triazole synthesis, the addition of the copper (I), the premium example of the click reaction, catalyst strongly activates terminal acetylenes towards the 1,3-dipole in…

The aim of this study is to find out and analyze the role of gender and age on the perceptions of students to the distant online program offered by Vocational High School in Sakarya University. The research is based on a questionnaire as a mean of data collection method to find out the role of age and gender on the student's perceptions toward…

Recent cases have demonstrated that plagiarism is a hot-button issue. It is also pervasive, occurring in universities, four-year colleges, community colleges, secondary schools, graduate programs, international classrooms, multicultural classrooms, writing centers, writing-across-the-curriculum programs, scholarly publications and the popular…

This research effort compared and contrasted two conceptually different methods for the exploration of human anatomy in the first-year dissection laboratory by accomplished students: "physical" dissection using an embalmed cadaver and "digital" dissection using three-dimensional volume modeling of whole-body CT and MRI image sets acquired using…

The purpose of this study is to explore the learning effect related to different learning styles in a Web-based virtual science laboratory for elementary school students. The online virtual lab allows teachers to integrate information and communication technology (ICT) into science lessons. The results of this experimental teaching method…

This study examines the practical work of a pair of students and an instructor using probeware in a mechanics lab. The aim of the study is to describe and discuss a type of interactional sequence that we refer to as "dark matter", the ordinary backdrop to the extraordinary sequences that are easily recognizable as clear-cut instances of learning.…

Combining field experience with use of information technology has the potential to create a problem-based learning environment that engages learners in authentic scientific inquiry. This study, conducted over a 2-yr period, determined differences in attitudes and conceptual knowledge between students in a field lab and students with combined field…

Researchers argue that teachers' beliefs are the final barrier that prevents technology integration. To affect change in teacher candidates' beliefs of technology integration, we created a pedagogical laboratory as well as a field experience program that operates within the pedagogical laboratory. This article presents a qualitative study of…

The purpose of this study is to investigate the effect of the use of group works and demonstration experiments based on conceptual change approach in the elimination of misconception about the subject of photosynthesis and respiration in plants in pre-service science teachers. This study was conducted with 78 pre-service science teachers including…

The Information Group at Millipore has been successfully using a digital rights management tool to secure the email distribution of archived laboratory notebooks. Millipore is a life science leader providing cutting-edge technologies, tools, and services for bioscience research and biopharmaceutical manufacturing. Consisting of four full-time…

The Department of Biological Sciences at the University of Wisconsin-Parkside has developed and implemented an innovative, multidisciplinary undergraduate curriculum in Molecular Biology and Bioinformatics (MBB). The objective of the MBB program is to give students a hands-on facility with molecular biology theories and laboratory techniques, an…

A number of tools and techniques have been developed to assist students with blindness and visual impairment who are studying in secondary and post-secondary science laboratories. Commercial electronic probes and their associated software packages allow real-time viewing and collection of data using a personal computer; however, until now, these…

Having established the "Writing Lab" at James Madison University in 1974, the author has watched the evolution and proliferation of Writing Centers in colleges and universities over the past 32 years. Common to support services at the beginning of her career as a writing specialist and in the present Writing Center are two primary areas…

The term "blended learning" is being used increasingly to describe the learning and teaching activities which involve a mixture of online teaching and face-to-face teaching. This paper describes the requirements of distant learning engineering courses, and proposes that a blended learning model suits best to the needs of such courses…
