This article describes how case studies have been successfully implemented in an introductory biology course of 300+ students using available technologies ranging from WebCT, used to assign students to permanent small groups (as well as assign groups to regions of a large lecture hall), to hand-held response systems (aka "clickers"), which…

Using "Science News" as a teaching tool promotes writing about science, talking about science, and broadening students' views about what science is. This article describes an ongoing assignment in which students choose one article from "Science News" each week and write a brief summary and explanation of why they picked that article. (Contains 1…

The time and effort spent during the first days of a new semester are key to the success of the class that lies ahead. What happens during these first days can set a tone that inspires students to work actively and cooperatively to achieve success in the new semester, or to sit back and assume a "here we go again" attitude. In this article, the…

Science education reform requires innovative professional development initiatives. Here we report the success of an interdisciplinary learning circle that met regularly over the course of a year to explore pedagogical theory and develop action research projects with the goal of improving critical-thinking skills in math and science undergraduates.…

I developed writing assignments for an introductory ecology class to encourage nonmajors to improve their writing skills and gain an appreciation for environmental issues. Statistical analyses suggest that during the semester, students' writing skills, their ability to write accurately about the environment, and their environmental behavior all…

The use of a photocopier to archive exams consumes photocopier resources and generates a large amount of waste. As an alternative, I have been using a consumer-grade digital camera to document exams in an upper-division biology course. The approach is inexpensive and offers a number of advantages over photocopies. (Contains 2 figures.)

Many studies show students benefit from working cooperatively. Rarely published in STEM literature are guidelines to help educators effectively incorporate research teams in the classroom. We explain how to create a positive learning experience by explaining group dynamics, and by using group contracts and team-building activities. We also share…

Two geoscience course sections were provided with lecture content in different formats--one with static text that contained no graphics, the other with a link to a virtual lecture. Follow-up quizzes showed no difference in learning between the two sections, yet attitudes and academic performance differed with gender. (Contains 2 figures and 1…

Triangulation involves the careful reviewing of data collected through different methods in order to achieve a more accurate and valid estimate of qualitative results for a particular construct. This paper describes how we used three qualitative methods of data collection to study attitudes of students toward graphing, hands-on activities, and…

The ELMO (Embedded Learning Modules) curriculum reform project has designed science curricula for specific nonscience students that fulfill core requirements and demonstrate how science can be engaging and relevant. ELMO students experience science through active learning and group activities that encourage them to make connections between science…

Demonstrations have long been part of postsecondary science teaching. Teachers understand that in today's constructivist classroom, students must be involved in their learning. This need for active student involvement extends to all aspects of instruction, including learning from demonstrations. Active demonstrations that engage students and…

Evaluation of teaching remains an inaccurate undertaking. Many believe that taking into factor the numbers of classes taught, students taught, graduate students supervised, honors contacts made, and undergraduates mentored are the best quantifiable measures for teaching. However, this author argues that such measures do little to provide a useful…

One effective method to improve the learning of science is through case study teaching. Teachers use realistic or true narratives to provide opportunities for students to integrate multiple sources of information in an authentic context, and may engage students with ethical and societal problems related to their discipline. However, little…

The process of protein synthesis, translation, is difficult for many students to understand. There are two reasons for this: (1) It is difficult to visualize the process, since the components involved in the process are not observable, and (2) There are many details, often dependent on each other and difficult to grasp independently, that are…

A narrative in the form of a courtroom trial is used to compare evidence on the nature of light as part of an introductory college physics course. Prosecuting and defense attorneys present evidence for and against competing wave and particle hypotheses for light behavior while students play the roles of jurors. (Contains 5 figures.)
