This lab is a computer simulation of transmission genetics. It presents students with a genetic phenomenon--the inheritance of a randomly--selected trait. The students' task is to determine how this trait is inherited by designing their own crosses and analyzing the results produced by the software.

This research studied a series of videoconference teaching workshops and virtual labs, which formed a component of a school-scientist partnership involving a New Zealand science research institute and year 13 students at a Wellington high school. It explored students' perceptions of the effectiveness of the videoconferences as an interactive…

Undergraduate research experiences are considered an essential component in college curricula, and there is an ideological push to provide these experiences to all students. However, it is not clear whether engagement in research is better suited for higher ability undergraduates late in their programs or for all undergraduates and whether…

In this paper we identify some of the issues and problems that we confronted while developing a new, one-semester, interdepartmental, multidisciplinary capstone design course. We implemented the following changes to the pre-existing capstone design course: (1) Utilized a website to enhance information transfer, (2) Modularized the course and…

This study examines the writings of the French educational psychologist Guy Brousseau to see how his situation-centered theories shed light on the learning in a computer laboratory associated with a community college mathematics class. Like the community college's laboratory, Brousseau's theories intend to help students construct mathematical…

This research entails integrating two novel approaches for enriching student learning in chemistry into the context of the general chemistry laboratory. The first is a pedagogical approach based on research in cognitive science and the second is the green chemistry philosophy. Research has shown that inquiry-based approaches are effective in…

Solubility is challenging for many general chemistry students, and the interactions of aqueous species are difficult to conceptualize. Derived from the pedagogies of Johnstone, Bloom, and Piaget, our primary research questions probe whether students' conceptual understandings of solubility could be enhanced by participation in a concept-building,…

This research investigated the effect of reflective discussions following inquiry-based laboratory activities on students' views of the tentative, empirical, subjective, and social aspects of nature of science (NOS). Thirty-eight grade six students from a Lebanese school participated in the study. The study used a pretest-posttest control-group…

In fall 2001, the University of Pennsylvania opened a public elementary school a few blocks away from its West Philadelphia campus. With the opening of this school, Penn joined the list of colleges and universities that have recently gone into the business of operating elementary or secondary schools. In each situation, the university role differs…

Preservice elementary education students often do not have a good feel for the process of science. Many may be acquainted with the steps of the scientific method but have never been through the scientific process. An exercise was designed using temperature-logging iButtons (Thermochrons) to improve knowledge of and familiarity with the process of…

To determine the carbonation degree of materials used in mineral carbonation experiments, a fast, simple, and sufficiently accurate method is required. For this purpose, a method based on the reaction between carbonates and hydrochloric acid was developed. It was noted that this method could also be used to teach undergraduate students some basic…

A series of online interactive teaching units have been developed that illustrate the use of experimentally measured three-dimensional (3D) structures to teach fundamental chemistry concepts. The units integrate a 500-structure subset of the Cambridge Structural Database specially chosen for their pedagogical value. The units span a number of key…

The success of interdisciplinary research teams depends largely upon skills related to team performance. We evaluated student and team performance for undergraduate biology and mathematics students who participated in summer research projects conducted in off-campus laboratories. The student teams were composed of a student with a mathematics…

This paper presents a wind power system laboratory activity and an outline for evaluating student performance in this activity. The work described here was to design and implement the laboratory to assist teachers in achieving the teaching objective of this activity. The laboratory teaching activities introduce energy sources, wind energy…

President Barack Obama recently issued a call for increased hands-on learning in U.S. schools in an address at the National Academy of Sciences. Obama concluded that the future of the United States depends on one's ability to encourage young people to "create, and build, and invent." In this article, the author discusses National Lab Day (NLD)…
