This study examines the initial integration of engineering design in an introductory preservice elementary biology content course using a life science design task focused on composting. The task, informed by a three-dimensional learning approach, required preservice teachers to research and model the process and use of composting to help the…

In this article we describe a course on science outreach that was developed as part of our college's goal that all students participate in a meaningful community engagement experience. The Science & Community Engagement course provides a way for students with science or science-related majors to learn how to effectively communicate scientific…

This article showcases how a physics lab course was successfully redesigned to promote important reasoning abilities not explicitly addressed in the typical college setting. Student development of such abilities is essential for sound decision making, particularly when living in an information age. Essential features of our guiding curricular…

We describe a hands-on, collaborative activity designed to illustrate general properties of evolution, provide practice for quantitative skills, promote creativity and collaboration, and enable student self-assessment of learning. During the activity, teams construct bridges using common office supplies. The best-performing bridge becomes the…

This article provides readers with details concerning the implementation of four active learning techniques used to help undergraduate students critically discuss primary literature. On the basis of undergraduate and graduate student perceptions and experiences, the authors suggest techniques to enhance the quality of dual-listed courses and…

One of the concepts taught to science students is the use of hemocytometer. Students in microbiology, genetics, and anatomy and physiology (A&P) classes use the hemocytometer in a variety of activities. In microbiology and genetics classes, it is used to quantify yeast cells, while in A&P classes; students learn how to count blood cells. This…

Two separate writing-to-learn activities in which students wrote to authentic audiences outside of the instructor were used in a college integrated science course, Science of Water. For the first task, students were asked to write to fourth-grade students, and for the second, students were asked to write to their academic advisor. An overview of…

Most students have heard about situations in which the paternity of a child is questioned; in a surprising reversal, in this case study, maternity is in question. Designed for an introductory biology course, the case involves concepts from genetics, inheritance, and the formation of pedigrees. Students develop hypotheses to explain how a mother…

Hypotheses of population genetics are derived and tested by students in the introductory genetics laboratory classroom as they explore the effects of biotic variables (physical traits of fruit flies) and abiotic variables (island size and distance) on fruit fly populations. In addition to this hypothesis-driven experiment, the development of…

Described is an application of educational technology that serves 700 students enrolled in 7 biology courses. Audiovisual and computer-assisted instruction are included. The integration of interactive audio with computer software is highlighted. (CW)

Discusses the use of self-directed learning in a large group class. Describes a workshop for developing group communication skills. (YP)

This research confirms the hypothesis that test achievement in general college chemistry is directly related to student participation in the learning process. (Author/DF)

Examines the following five teaching techniques that have strong motivational value: (1) study groups, (2) group projects, (3) sharing information, (4) computer-assisted instruction, and (5) field trips. (PR)

Describes the goals, procedures, and activities of a Computers in Chemistry course for undergraduate chemistry majors. Provides a listing of topics which have user-friendly programs and of representative activities which have been incorporated into the course. Also includes suggestions for student assignments. (ML)

Describes a laboratory exercise that introduces physics students to graphing. Presents the program format and sample output of a computer simulation of an experiment which tests the effects of sound intensity on the crawling speed of a snail. Provides students with practice in making exponential or logarithmic graphs. (ML)
