In this paper, we seek to evaluate the extent to which students can follow a deductive reasoning chain when it is presented to them. A great deal of instruction in introductory physics courses is centered on presenting students with a logical argument that starts from first principles and systematically leads to a particular conclusion. This…

If an organic chemistry student explains that she represents a mechanistic step because ''it's a productive part of the mechanism,'' what meaning could the professor teaching the class attribute to this statement, what is actually communicated, and what does it mean for the student? The professor might think that the explanation is based on…

The ability to evaluate options and make informed decisions about problems in relevant contexts is a core competency in science education that requires the use of both domain-general and discipline-specific knowledge and reasoning strategies. In this study we investigated the implicit assumptions and modes of reasoning applied by individuals with…

The empirical validity of generalizability theory was investigated by applying two three-facet designs to data obtained in 1988 from administration of the Scientific Thinking and Research Skill Test (STRST). The decision validity of the STRST was also examined. Subjects were 125 fifth-grade and 125 sixth-grade students who were administered the…

Teaching strategies are becoming increasingly oriented toward guiding students' knowledge construction through cooperative learning. Enhancing students' cognitive development is a priority; students must "learn how to think." Inquiry instruction provides students with tools to make decisions based upon available evidence and an opportunity to…
