The polymerase chain reaction (PCR) is a common technique used in high school and undergraduate science teaching. Students often do not fully comprehend the underlying principles of the technique and how optimization of the protocol affects the outcome and analysis. In this molecular biology laboratory, students learn the steps of PCR with an…

Described are techniques used in a course designed to teach biology as a process to improve students' skills in critical thinking, reasoning, and writing. Results which indicate improved performance on subject-content tests, increased student motivation, and understanding of science as a process are stated. (RT)

Described is a simulation game designed to reinforce the biological concepts of poisoning, encourage critical thinking and deductive reasoning, and be enjoyed by the students. Discussed is the plot design, the setting, the characters, the analysis, and results of the simulation. Examples of the data and case histories generated by this game are…

Virology is an integral part of introductory biology courses. Research and experience indicate that, although the topic is a difficult one for many students, the effectiveness of instruction is enhanced when assignments actively engage the students in the generation of scientific explanations. These authors have found that the methods and…

Recent education reform efforts are at the forefront of educators' minds across the nation, science teachers notwithstanding. At least 48 states have developed a mandated standardized test, the majority of which also publish an individual school proficiency report. Washington State's new standardized science test is an example of such reforms…

Teaching methods of genetic analysis such as fluorescence in situ hybridization (FISH) can be an important part of instructional units in biology, microbiology, and biotechnology. Experience, however, indicates that these topics are difficult for many students. The authors of this article describe how they created an activity that effectively…

Explains the use of a modification of an approach known as the Line of Reasoning (LOR) model to critique science news articles. Argues that popular press articles lack scientific evidence to support the claims made and instead focus on evidence-based inference. (DDR)
