Presents a programed method that inventories and classifies hazards. 8iscusses the following topics: (1) student and hazard source, (2) elimination of the source, (3) adaptation of the source, (4) isolation of the source, (5) adjustment of the surroundings, (6) isolation of man, and (7) personal protective equipment. (MVL)

Provides a point of view that the organic lab is a good place for the student to use and learn problem solving skills while performing the cookbook experiments. Notes that an equilibrium between the theoretical and practical aspects of organic chemistry should be established. (MVL)

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Describes the Alabama Science in Motion Program (ASIM) which provides hands-on science laboratories to high school students. Discusses the benefits of the program for host teachers and its impact on students and preservice teachers. (YDS)

Internet learning opportunities via the National Science Foundation-supported New Jersey Networking Infrastructure in Education project are described. Their data-centered approach to science and math skills instruction is illustrated by two examples from each of the three styles of activities: (1) collaboration; (2) using public domain databases;…

This article discusses the rules science teachers need and how to implement these rules in the class. What should my science classroom rules be? Ideally, this question is asked prior to the teacher's entry to the classroom during their teacher training and revisited throughout their coursework preparation and student teaching. A science teacher…

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The…

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

We describe an eight-week summer Young Scientist in Training (YSIT) internship program involving middle and high school students. This program exposed students to current basic research in molecular genetics, while introducing or reinforcing principles of the scientific method and demonstrating the uses of mathematics and chemistry in biology. For…

As students apply their knowledge of scientific concepts and of science as a method of inquiry, learning becomes relevant. This laboratory exercise is designed to foster students' understanding of the genetics of quantitative traits and of the nature of science as a method of inquiry by engaging them in a real-world business scenario. During the…

We report on the development of students' ideas of probability and probability density in a University of Maine laboratory-based general education physics course called "Intuitive Quantum Physics". Students in the course are generally math phobic with unfavorable expectations about the nature of physics and their ability to do it. We…

Some learning scientists are beginning to investigate social and cultural aspects of learning by examining the interactions between a learner and the environment as well as with other people in the learning environment. This article proposes conversational analysis (CA) as a tool to analyze interactions between learners and instructors in…

This study aimed to identify the types of arguments promoted in various contexts common to a high school chemistry classroom, including lecture-discussion and laboratory activities. The study was guided by the following research question: What types of argument structures and schemes, if any, are promoted and engaged by students within various…

For the thirty-sixth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Anaheim, California. The Proceedings of AECT's Convention are published in two…

Increasingly, national stakeholders express concern that U.S. college graduates cannot adequately solve problems and think critically. As a set of cognitive abilities, critical thinking skills provide students with tangible academic, personal, and professional benefits that may ultimately address these concerns. As an instructional method, writing…
