The assumption that students will acquire positive attitudes toward science as they learn more science is no longer valid. This study confirmed the reliability of the Biology Attitude Scale. Whether a student is a biology major or nonmajor is not a determining factor when measuring the effect an introductory course has in changing attitudes toward…

Presents an active-learning technique in which students design their studies that was found to be successful in an animal behavior laboratory course. Divides the laboratory course into three components: (1) structured and technique-oriented exercises; (2) open-ended and student-designed investigations; and (3) independent projects. Explains…

Argues for the use of instruments in introductory level chemistry and presents multiple perspectives on the issue. Reasons for employing instrumentation include the ability of introductory classes to reach a large number of students, the need to model situations in which scientists work, and student expectations regarding the use of technology.…

College students learned how to design the roots, stem, and leaves of plants to survive in five different virtual reality environments through an agent-based multimedia educational game. For each student, the agent used personalized speech (e.g., including I and you) or nonpersonalized speech (e.g., 3rd-person monologue), and the game was…

This study explores how individuals make use of scientific content knowledge for socioscientific argumentation. More specifically, this mixed-methods study investigates how learners apply genetics content knowledge as they justify claims relative to genetic engineering. Interviews are conducted with 45 participants, representing three distinct…

One of the challenges in teaching biochemistry is facilitating students' interest in and mastery of metabolism. The many pathways and modes of regulation can be overwhelming for students to learn and difficult for professors to teach in an engaging manner. We have found it useful to take advantage of prevailing interest in popular yet…

We describe an innovative bioinformatics course developed under grants from the National Science Foundation and the California State University Program in Research and Education in Biotechnology for undergraduate biology students. The project has been part of a continuing effort to offer students classroom experiences focused on principles and…

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…

This article describes the curriculum for a highly student-centered human biology course constructed around a series of themes that enables the integration of the same basic paradigms found in a traditional survey lecture course without sacrificing essential content. The theme-based model enhances student interest, ability to integrate knowledge,…

The Senior Seminar in Biology course at Kean University teaches students who have taken core biology courses and achieved senior status to research primary literature on current topics in biology and produce a traditional seminar presentation that includes a written report and a clear and comprehensive oral talk with ensuing discussion. Senior…

In this interrupted case study, based on a journal article on the parenting behavior of American coots, students are given information and data from which they must develop hypotheses and design experiments, mimicking the way that scientists conduct research. The case is appropriate for courses in biology, especially those focusing on evolution…

A university in Buffalo introduced its students to evolution by providing them with information on evidence of evolution, mechanisms for evolution, principles of genetics, selection, adaptation, evolution and sociobiology. This method of teaching with technology enabled students to improve and expand their learning opportunities.

The rapidly changing field of bioinformatics is fuelling the need for suitably trained personnel with skills in relevant biological "sub-disciplines" such as proteomics, transcriptomics and metabolomics, etc. But because of the complexity--and sheer weight of data--associated with these new areas of biology, many school teachers feel…

Leaves of higher terrestrial plants have small pores--stomata--responsible for gas exchange. The opening of each stoma results from the osmotic uptake of water by two specialised cells--the guard cells. Because of the involvement in this mechanism of ATPase-proton pumps and active transport of ions across membranes, we have designed an Exploring…

Our pre-university chemistry students face problems achieving sufficient quality in chemical inquiry. To try to enhance the quality of student performance in chemical inquiry, Dutch pre-university chemistry students (age 17) carried out an authentic research project on "Diffusion of ions in distilled water." The learning materials for this student…
