This study focuses on 11 African American undergraduate seniors in a biology degree program at a predominantly white research institution in the southeastern United States. These 11 respondents shared their journeys throughout the high school and college science pipeline. Participants described similar precollege factors and experiences that…

We describe a simple, yet intellectually challenging model of grazing systems that introduces basic concepts in ecology and systems analysis. The practical is suitable for high-school and university curricula with a quantitative orientation, and requires only basic skills in mathematics and spreadsheet use. The model is based on Noy-Meir's (1975)…

The life scientist's professional activity is much more than just laboratory work. Information search and retrieval and later communication of conclusions are important and substantial matters. How to manage knowledge is essential for the future scientific or technological careers of college students. Nevertheless, knowledge management is…

The study and utilisation of pendulum motion has had immense scientific, cultural, horological, philosophical, and educational impact. The International Pendulum Project (IPP) is a collaborative research effort examining this impact, and demonstrating how historical studies of pendulum motion can assist teachers to improve science education by…

This paper discusses the potential of applying computer-animated instruction (CAnI) as an effective conceptual change strategy in teaching electrochemistry in comparison to conventional lecture-based instruction (CLI). The core assumption in this study is that conceptual change in learners is an active, constructive process that is enhanced by the…

Program-level assessment of the biology curriculum at a small liberal arts college indicates progress in the development of communication skills and content knowledge. The authors propose a mechanism to provide more research opportunities for students, giving them all the tools necessary to do science. (Contains 5 figures.)

Bioscience undergraduates, enrolled on a first-year microbiology module, participated in the introduction of peer-assisted learning (PAL) into the curriculum. The class of 122 students was divided into groups of six to ten, with one volunteer from each group assuming the role of group leader (peer tutor). Group leaders attended a compulsory…

In Astronomy 101 at the University of New Mexico, we carried out a repeated-items experiment on quizzes and tests to investigate the impact of cooperative testing. This trial was the only change in a reformed course format that had been refined over previous semesters. Our research questions were: (1) Did cooperative quizzes result in gains for…

There are many questions to be asked about the pedagogical practice of questioning. Questions provide insight into what students at any age or grade level already know about a topic, which provides a beginning point for teaching. Questions reveal misconceptions and misunderstandings that must be addressed for teachers to move student thinking…

In this article, the author describes three reports conducted by the National Academies, a private, nonprofit organization whose charter is to assist the federal government and the American people in analyzing pressing science and technology policy issues. These reports are: (1) "Rising Above the Gathering Storm: Energizing and Employing…

This article describes how a traditional biology lecture course was transformed into an interactive class. A review the activities used, changes made to grading policy, and practical tips for integration of active learning in the classroom are provided. Analysis of student responses to course assessments indicated that active learning experiences…

A main challenge in educating undergraduate students is to introduce them to the Internet and to teach them how to effectively use it in research. To this end, an Internet assignment was developed that introduces students to websites related to biomedical research at the beginning of a biochemistry/molecular biology laboratory course. The basic…

In contrast to most other thermodynamic data, entropy values are not given in relation to a certain--more or less arbitrarily defined--zero level. They are listed in standard thermodynamic tables as absolute values of specific substances. Therefore these values describe a physical property of the listed substances. One of the main tasks of…

An important learning goal of a molecular biology curriculum is the attainment of a certain competence level in experimental design. Currently, undergraduate students are confronted with experimental approaches in textbooks, lectures and laboratory courses. However, most students do not reach a satisfactory level of competence in the designing of…

The spaces and structures used for undergraduate science often work against new teaching methods and fail to provide environments that attract the brightest students to science. The undergraduate science building often offers little to inspire the imaginations of young minds. The typical undergraduate science building also tends to work against…
