This hypothesis-driven laboratory exercise teaches how DNA evidence can be used to investigate an organism's evolutionary history while providing practical modeling of the fundamental processes of gene transcription and translation. We used an inquiry-based approach to construct a laboratory around a nontrivial, open-ended evolutionary question…

Laboratory exercises using "Drosophila" crosses are an effective pedagogical method to complement traditional lecture and textbook presentations of genetics. Undergraduate thesis research is another common setting for using "Drosophila." A significant barrier to using "Drosophila" for undergraduate teaching or research is the time and skill…

"Name That Gene" is a simple classroom activity that incorporates bioinformatics (available biological information) into the classroom using "Basic Logical Alignment Search Tool (BLAST)." An excellent classroom activity involving bioinformatics and "BLAST" has been previously explored using sequences from bacteria, but it is tailored for college…

The Rural and Small Schools Conference has made a special effort to address the needs that pertain to science educators in rural and small schools. This publication presents the proceedings from the 1988 science education section of the conference. The content of the conference deals with a diversity of topics. The proceedings include a preface…

This paper discusses the relationship between the work that takes place in science laboratories and the science curriculum that is presented in the schools. The introduction asserts that although science education identifies itself with the scholarly disciplines of science, science educators should devise curricula that fairly represent these…

A survey of 102 New Jersey secondary school science teachers, department chairpersons, and supervisors concerning their laboratory accident-rate was conducted during the 1981-82 school year. Results indicate that accidents occur on a weekly basis even among a sample of experienced teachers who were interested in safety. The number of accidents…

The use of of the Automatic Interaction Detector (program AID3 of the OSIRIS statistical package) to study a university program is discussed. The performance of students who took general physics lecture and laboratory concurrently is compared to the performance of those who took them separately. Five years of data are analyzed, covering 1,997…

This monograph discusses the current practices associated with the conduct of a research and experimentation program in technology education. It describes the background and bases of the program, the role of the teacher of research and experimentation, and advantages of the program. Next, the environment of the program is addressed, including the…

The purpose of this experiment was to compare an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning at two private, midwestern liberal arts colleges. Intact laboratory sections of students enrolled…

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

During the 1984-85 school year, questionnaires were mailed to 358 science teachers in all regions of North Carolina to determine what they thought about the value of laboratory activity as one of their teaching methods and their feelings about the mechanics of using this methodology. Without a follow-up, 52.2 percent (N=187) of the questionnaires…

This booklet, the second in a series, reports on the results of a year-long research project conducted in an experimental school associated with the Learning Research and Development Center, University of Pittsburgh. Specifically, this is a report of findings pertaining to one major setting in the experimental school, the science lab. The science…

The small size of many schools in the Asian Region would cause separate laboratories for chemistry and biology to be underutilized. In many larger schools the curricula include "general science," with contents from biology, physics, and chemistry. This paper describes multipurpose spaces for science activities sufficient for science…

Designed to evaluate the use of microcomputer-based labware (MBL) in junior high school science, the Computer as Lab Partner Project examined classroom experience of using MBL; system features used and curriculum designed; classroom procedures, processes, and interactions; gains and benefits of MBL use; and potential difficulties in MBL…

Discusses the need for more safety instruction in high school and college chemistry courses. Reports on a national survey of 2019 college and university chemistry departments. Includes survey results and the descriptions of 50 accidents which the institutions reported. (TW)
