The introduction of Green Chemistry (GC) into school science curriculum is considered an important step that encourages students to build connections between chemistry, other school subjects, and different aspects of their daily lives. The concepts associated with GC can be applied throughout the various levels of education with different degrees…

The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

This dissertation is the product of several individual multi-disciplinary investigations that cover a variety of topics in mathematics, physics, geology, and geoscience education. The first chapter formulates a better understanding of the timings, magma source, and relationships between dikes and associated magmatic bodies of the Red Bluff…

The present article analyses the changes in practices, ideas, and attitudes proposed by a group of novice science teachers during a further education teacher training program. The research on which it is based is focused on monitoring the training program and its impact on the participating teachers. The training program has as its starting point…

The National Science Foundation funded a synthesis study on the status, contributions, and future direction of discipline-based education research (DBER) in physics, biological sciences, geosciences, and chemistry. DBER combines knowledge of teaching and learning with deep knowledge of discipline-specific science content. It describes the…

Four science programs at our public urban liberal arts college have struggled to attract and retain majors: physics, environmental studies, geology, and teaching science. The Brooklyn Opportunities in Science and Careers (BOSC) program aims to increase student participation in these majors using a new career-focused strategy to recruit students.…

The intention of this study was to determine how science instructors in the university laboratories spend time on instruction. The study, was guided by three research questions and two hypotheses tested at 0.05 level of significance. The study employed a non-participant observation case study design. 48 instructors teaching lower and higher levels…

Using visual models is common in science and should become more common in classrooms. Our research group has developed and completed studies on the use of a visual modeling tool, the Concept Connector. This modeling tool consists of an online concept mapping Java applet that has automatic scoring functions we refer to as Robograder. The Concept…

The purpose of this study was to understand how Thai scientists from four disciplines viewed nature of science (NOS). The sixteen participating scientists were chosen from the areas of chemistry, physics, biology/life sciences, and geology/earth sciences and were separated into novice and expert groups. The scientists' understandings about NOS…

Described are several aspects and methods of quantitatively measuring geologic time using a constant-rate natural process of radioactive decay. Topics include half lives and decay constants, radiogenic growth, potassium-argon dating, rubidium-strontium dating, and the role of geochronology in support of geological exploration. (DS)

Discusses common as well as uncommon minerals that are attracted to a hand magnet. Included in the discussion are answers to the following questions: (1) What causes this attraction? and (2) How many different minerals respond to a hand magnet? (ZWH)

The use of accelerators as mass spectrometers puts the work horse of isotope dating on a new, more useful footing. (Author/BB)

Describes a college level exercise in physics for measuring the earth's resistivity. (SL)

Suggests an integrated approach to make science teaching and learning more effective, interesting and motivating to students. Argues that team teaching by physics and geology departments enables students to learn concepts and principles of physics and apply them to solve geological problems facing the local community. Reports that a typical…
