The Gateway Science Workshop is a peer-facilitated, problem-focused program designed to improve student retention in the sciences. This article discusses its development, implementation, and efficacy, which is demonstrated by higher retention of workshop students in the course sequences. Evidence suggests that the program has particular benefits…

I altered the format of an exercise physiology course from traditional lecture to emphasizing daily reading quizzes and group problem-solving activities. I used the SALGains evaluation to compare the two approaches and saw significant improvements in the evaluation ratings of students who were taught using the new format. Narrative responses…

Outbreak! is an online, interactive educational game that helps students and teachers learn and evaluate clinical microbiology skills. When the game was used in introductory microbiology laboratories, qualitative evaluation by students showed very positive responses and increased learning. Outbreak! allows students to design diagnostic tests and…

This article explores the problem of assigning grades to students engaged in nontraditional activities, especially scientific inquiry. We suggest using scoring rubrics to guide students in their work and to assist teachers with grading. We present the steps involved in the construction of rubrics, and we show sample rubrics. (Contains 5 figures.)

Inquiry is an important learning strategy, even for students who cannot or do not perform actual experiments. We describe two activities, other than experimentation, that we used in introductory biology learning groups to emphasize inquiry abilities. We also provide recommendations for creating additional inquiry activities. (Contains 1 table and…

We conduct research workshops twice each semester in our cell biology lecture course. Instead of solely analyzing data obtained by others, students form groups to design research questions and experimental protocols on a given topic. The main focus is the process of scientific thinking, not simply obtaining a correct product. (Contains 3 tables…

A wonderful way to engage science students is to make them think a demonstration is not turning out the way the instructor intended. Basically, throw a little humor into teaching, and they will be hooked. Described in this article is a demonstration that uses Milk of Magnesia (MOM) as a visual and humorous method to review equilibrium chemistry…

One of the unifying themes of modern biology is evolution. In introductory biology courses, evolution is studied in some detail and used as a focal point for many courses. For many teachers of those courses, the greatest frustration is their inability to help students become Darwinian. Students do not reject evolutionary ideas, but they quickly…

This case was developed for a sophomore organic chemistry lab to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist: Two bodies have been recovered from two different lakes, but because of a mix-up at the morgue, the coroner is unable to…

This case involves a couple deciding whether or not their son should undergo brain surgery to treat a severe seizure disorder. In examining this dilemma, students apply knowledge of brain anatomy and function. They also learn about brain scanning techniques and discuss the plasticity of the brain.

This case explores the genetics and evolution of skin color, using a short story by Kate Chopin called "Desiree's Baby" as a starting point. Students read the story and discuss a series of questions probing the genetics of the family in the tale. Students then read an article about the evolution of skin color and write an essay analyzing the…

This case is based on an article that considered the problems that would arise if a person were to cross over into a mirror-image environment (Yee 2002). Some of the stereochemistry problems posed in that article are woven into this case study. (Contains 8 figures.)

This case teaches students to be skeptical of "scientific claims," especially those that are sensational and fall outside the boundaries of normal scientific explanation. Students read the case scenario and then evaluate data to determine whether they believe there is enough scientific evidence to confirm the existence of extrasensory perception.…

A high school hockey team is playing the last of three games in one day. The game gets rough, and the star player is slammed against the boards. Injured, he is escorted off the ice. This case follows his health as it deteriorates over the next several hours. Students are presented with the hockey player's symptoms, and they use their knowledge of…

In this interrupted case, students read about the alarm-calling behavior of a certain type of ground squirrel and then work in groups to develop hypotheses to explain the behavior and describe data that might be used to test their hypotheses. Students are then given real data and asked to interpret the evolutionary relevance of the results.…
