Membrane transport is a fundamental concept that undergraduate students of cell biology understand better with laboratory experience. Formal teaching exercises commonly used to illustrate this concept are unbiological, qualitative, or intricate and time consuming to prepare. We have developed an exercise that uses uptake of radiolabeled nutrient…

Introduction of new teaching strategies often expands the expectations for student learning, creating a parallel need to redefine how teachers collect the evidence that assures both them and their students that these expectations are in fact being met. The default assessment strategy of the typical large, introductory, college-level science…

In this article, the authors highlight an issue in science education facing many university and college science departments: hiring faculty who can bring to the department specialized expertise in science education. To begin to address this issue, a collaborative team of tenure-track faculty--all of whom are primarily trained in science and have…

Gill-breathing freshwater snails (Family "Pleuroceridae") are ecologically important, abundant in many streams in the United States, and easy to collect and maintain under classroom conditions. These snails can be used in classroom tests to demonstrate effects of pollutants on aquatic organisms. In more advanced classes, students can cage the…

A research writing course was developed to prepare chemistry majors to conduct and report on their capstone research projects. The course guides students through a multistep process of preparing a literature review and research proposal. Students learn how to identify and avoid plagiarism, critically read and summarize a scientific article,…

A laboratory experiment is presented for the upper-level undergraduate physical chemistry curriculum in which the ternary phase diagram of water, 1-propanol and n-heptane is measured using proton nuclear magnetic resonance (NMR) spectroscopy. The experiment builds upon basic concepts of NMR spectral analysis, typically taught in the undergraduate…

Molecular biology concepts can be quite abstract and difficult to grasp for even the most talented student. Reducing potential frustration in the learning process, allowing students to take ownership of the course material, and training students to think critically and analytically are common objectives for educators. In this article, pedagogical…

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…

This article describes a course for nonscience majors that uses the issue of race in humans to stimulate interest in genetics and other sciences. Student outcomes, including valuing and understanding science, plus an ability to discuss the sensitive issue of race, are very positive.

Service learning projects were incorporated into the curriculum of an undergraduate course entitled "Biology of Women". The goals of the service learning projects were: 1) to provide students with the opportunity to consider issues pertaining to human biology in real-world settings; 2) to foster student engagement with the community; and…

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students' general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important…

We present results from a comparative study of student understanding for students who attended recitation classes that used different teaching methods. Student volunteers from our introductory calculus-based physics course attended a special recitation class that was taught using one of four different teaching methods. A total of 272 students were…

This article describes a novel, hands-on method to qualitatively determine the extent of microbial activity in topsoil using ordinary blank paper. Appropriate and scalable for the high school and college level, these experiments expose students to some of the challenges facing environmental researchers and also contribute to curriculum development…

Chemistry Is in the News (CIITN) is an innovative project aimed at enhancing higher-order cognitive skills (HOCS) via connecting university-level chemistry to everyday life and real-world issues. The CIITN project and its related Web tools were presented in a workshop to illustrate their conceptual framework, educational potential, and…

Open Source Software (OSS) has introduced a new dimension in software community. As the development and use of OSS becomes prominent, the question of its integration in education arises. In this paper, the following practices fundamental to projects and processes in software engineering are examined from an OSS perspective: project management;…
