A chemical laboratory information profile (CLIP) is presented for the chemical, triethanolamine. It summarizes the chemical's physical and harmful features, exposure limits, and symptoms of major exposure for the benefit of teachers and students, who use the chemical in the laboratory.

A laboratory exercise incorporating biological keying into student learning, where students work together in cooperative learning setting is presented. The exercise fosters cooperative learning and accountability because the whole group is responsible for the final product.

The problem with organic chemistry labs is that the educational objectives of lab instructions are often vague and seldom stated. The great majority of organic chemistry labs in American colleges and universities are based on verification experiments.

An experiment developed for an undergraduate organic chemistry laboratory course that can be used to introduce the catalytic hydrogenation reaction, catalysis electrochemical principles and gas chromatography is presented. The organic compounds hydrogenated by the electrocatalytic hydrogenation (ECH) process were styrene, benzaldehyde and…

In this article, the author presents a poem on the distribution and adaptation of blue-green algae (Cyanobacteria). The poem describes some of the diverse habitats of cyanobacteria including examples from extreme and unique environments such as hot springs, and polar bear hair. The poem also describes some of the adaptations of cyanobacteria…

The experience and science expertise of these award-winning authors makes this easy-to-use guide a teacher's treasure trove. This latest edition to the popular What Successful Teachers Do series describes 75 research-based strategies and outlines best practices for inquiry-oriented science. Each strategy includes a brief description of the…

Undergraduate research experiences have been shown to enhance the educational experience and retention of college students, especially those from underrepresented populations. However, many challenges still exist relative to building community among students navigating large institutions. We developed a novel course called "Entering…

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.…

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…

Contemporary science standards stress the importance of highlighting inquiry in the science classroom as one way of learning key concepts. One critical question that needs to be addressed for a range of instructional practices is how opportunities to learn are conceptualized so that students can engage and learn the critical ideas and practices…

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…

The purpose of this study is to prepare inquiry based experimental activities on the photosynthesis, thought to be a very difficult subject by pupils, and to determine the pupil's ideas towards this method. This study was made with 24 pupils from Grade 3 at Ataturk Anatolian High school in Turkey. As data gathering material; seven inquiry…

The use of effective knowledge management is becoming an essential part of technical development projects in order to enable developers to handle the growing complexity of these projects. In this article we discuss an innovative approach to address this concern from the perspective of an undergraduate engineering curriculum. Instead of adding…
