DNA microarray is an ordered grid containing known sequences of DNA, which represent many of the genes in a particular organism. Each DNA sequence is unique to a specific gene. This technology enables the researcher to screen many genes from cells or tissue grown in different conditions. We developed an undergraduate lecture and laboratory…

Business education, as a discipline and profession, is evolving in response to changes in our domestic and global environment, technology, subject matter content, and needs of the end-user. In response to these changes, business educators continue to evaluate and refine their instructional methodologies and other components of delivery systems…

This Brief Report summarizes case studies of the classroom teaching practices of 2 algebra teachers. The data consist of videotaped classroom observations during 1 academic year. The study identifies and characterizes specific teaching practices that establish the norm that the teacher is the sole arbiter of mathematical correctness in the…

This qualitative case study examines the initial implementation of a problem-based version of an undergraduate course in materials science for the purpose of identifying areas of improvement to the curriculum prior to a planned second implementation. The course was designed around problems that students work in small teams to solve under the…

This brief review is meant to serve as a refresher for faculty teaching respiratory physiology to medical students. The concepts of ventilation and perfusion matching are some of the most challenging ideas to learn and teach. Some strategies to consider in teaching these concepts are, first, to build from simple to more complex by starting with a…

Obstructive sleep apnea (OSA) is a common disorder of upper airway obstruction during sleep. The effects of intermittent upper airway obstruction include alveolar hypoventilation, altered arterial blood gases and acid-base status, and stimulation of the arterial chemoreceptors, which leads to frequent arousals. These arousals disturb sleep…

Teaching students to write persuasive messages is a critical feature of any undergraduate business communications course. For the persuasive writing module in the author's course, students write a persuasive message on the basis of the four-part indirect pattern often used for sales or fund-raising messages. The course text she uses identifies…

Medical education in the United States and Canada continues to evolve. However, many of the changes in pedagogy are being made without appropriate evaluation. Here, we attempt to evaluate the effectiveness of lecture capture technology as a learning tool in Podiatric medical education. In this pilot project, student performance in an inaugural…

Economics is usually perceived as a difficult subject among undergraduate students and the literature suggests that the student's problems with principles of economics are mainly related to the chalk and talk type of teaching, the simplicity of economic models, limited discussions on current economic issues, and on race, gender, and other types of…

This paper was presented on the panel, "Perspectives on Teaching about Radio, Culture, and Society," sponsored by the Radio/Audio Media and International Divisions of the Broadcast Education Association (BEA) at the BEA National Convention. The purpose of the panel was to examine various perspectives - domestic and international - on…

In the past 30 years, university-level chemistry education in China has been experiencing significant changes because of the rapid expansion of its university education system. These changes are reflected in improvements to the existing education goals, classroom teaching methods, textbooks, teaching facilities, teacher profiles, lab activities,…

Many large scientific projects and scientific centres incorporate some kind of outreach programme. Almost all of these outreach programmes include public scientific lectures delivered by practising scientists. In this article, we examine such lectures from the perspectives of: (i) lecturers (7) who are practising scientists acknowledged to be good…

Student performance in lecture-based versus case study-based instruction was compared in this study. Case-based teaching that emphasized problem solving and discussion significantly improved student performance on exams throughout the semester and enhanced students' abilities to correctly answer application- and analysis-type questions. (Contains…

The use of toys in physics teaching is common. This brief review of the physics of toys intends to show that they are not only very useful in lectures and demonstrations in order to motivate students but also very interesting from a scientific point of view. However, since their physics is sometimes too cumbersome, the effect can be the opposite.…

We investigated whether an active learning approach, facilitated by a personal response system, would lead to improved student engagement and learning outcomes in large-group physiology lectures for undergraduate science students. We focused on encouraging students' active learning in lectures, whereas previous studies have made more use of…
