The use of William Perry's (1970) model of cognitive development during the college years to restructure an abnormal psychology course is described. The model provides a framework for students and teachers to understand the confusion and frustration they sometimes experience. Perry proposed that students enter college with tacit epistemological…

Presents a project that explored student choice of a solution method for quadratic inequalities. Students were first instructed in the use of the case, critical-number, and graphical methods using the graphing calculator. The majority of students chose graphical methods of solution. (DDR)

The concepts of social cognition and cognitive structures are important aspects of constructivism and human communication theory. By asking students to listen to different musical selections and fill in a simple rubric, different schemas become apparent. This creates an opportunity to discuss how cognitions relate to communication. Students who…

Discusses the difficulties that some students have in understanding the concept of chemical reactions. Proposes that instructors try to consider the various difficulties during a chemistry course when students form their concepts of element conservation. (TW)

Examines quantitative models in school physics, looking particularly at the degree to which they match the real world. Explores the positive aspects of a mismatch between models and real world conditions. (DDR)

Shows how box diagrams and AVOW diagrams may be used to solve problems concerning networks of resistors that obey Ohm's Law. Presents outcomes and feedback from students and teachers. Concludes with suggestions as to how these techniques might be incorporated into the teaching of basic circuit theory. (Contains 22 references.) (DDR)

This paper advocates for the improvement of presentational methods of teaching and expository learning, based on David Ausubel's theory of Meaningful Verbal Learning and its derivative, the Advance Organizer Model of Teaching. This approach to teaching enables teachers to convey large amounts of information as meaningfully and efficiently as…

Explains the philosophy that forms the basis of a high school physical science course based on astronomy and the activity-based textbook that accompanies it. Cites specific examples of misconceptions related to astronomy and recommends various diagnostic and concept change strategies. (DDR)

Proposes a theory for organizing information and activities in educational hypermedia systems and evaluates theory effectiveness based on implementation of a multimedia learning environment. Results suggest that self-paced interactive learning environments, multimedia information access, and constructive activities organized into cognitive media…

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Points out a misconception that is reinforced in many elementary and advanced chemistry texts. Discusses the general limitations of the orbital concept. Notes misconceptions related to the transition elements and their first ionization energies. (MVL)
