Background/Context: Many children of immigrants are not enrolled in high schools that sufficiently meet their needs, and subsequently, many are not making a successful transition to, and/or successfully completing, higher education. As immigration grows in the United States, educators and policy makers must understand how the educational processes…

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Addresses the importance of recognizing the prior knowledge and misconceptions of science educators. Provides perspectives on the nature of knowledge, conceptions of learning, nature of science and of teaching, and the relationship between general principles of learning and teaching. (ML)

Explains the differences between successful and unsuccessful problem solvers' exploration of a problem, translation of information into different forms, approach to devising and executing a plan, and rechecking work. (RT)

Analyzes the concept of teaching from various aspects. Reviews research on students' conceptions of natural phenomena, conceptual change, and teacher thinking. Suggests an appropriate conception of teaching science. (YP)

It is difficult for students to unlearn misconceptions that have been unknowingly reinforced by teachers. The examples "multiplication makes bigger,""pi equals 22/7," and the use of counter examples to demonstrate the numerical property of closure are discussed as potential areas where misconceptions are fostered. (MDH)

To make elementary science students grasp the scientific concepts being taught, teachers must not ignore their preconceived ideas. Instead, teachers must identify misconceptions then help the students test them. The article presents a step-by-step approach that can serve as a model for teaching any science concept. (SM)

Provides perspectives on information technology and science education. Reviews the major changes that have occurred during the last 20 years in the study of the mind that are relevant to science education. Focuses on the impact of computers and information technology. (ML)

Discusses the causes and effects of conceptual errors inadvertently introduced and nurtured by scientists, teachers, and textbook writers. Cites ways to prevent the communication breakdowns that prevent the learning of science. (RT)

Describes a teaching experiment that uses the Learning Cycle to achieve the reorientation of physics' students conceptual frameworks away from commonsense perspectives toward scientifically rigorous outlooks. Uses Archimedes' principle as the content topic while using the Learning Cycle to remove students' nonscientific preconceptions. (JRH)

Discussed is an alternative teaching strategy to uncover and assess a common misconception in the life sciences and to articulate its use in teaching a unit on angiosperm reproduction. The learning cycle is described, and a concept map on reproduction on angiosperms is included. (KR)

Recent research in cognitive science and science education suggests that science-naive individuals have an understanding of the natural world based on their interpretation of everyday experience. This can make the process of conceptual change difficult. This paper presents ideas related to the acquisition of knowledge in astronomy. A theoretical…

Describes a multiple-choice instrument that reliably and validly diagnoses secondary students' understanding of photosynthesis and respiration in plants. Highlights the consistency of students' misconceptions across secondary levels and indicates a high percentage of students have misconceptions regarding plant physiology. (CW)

Described is a study of 147 students that indicated a high proportion of students did not understand the concept of limiting factors. Textbook presentations that create problems are discussed. Strategies which may be more effective in teaching the concept are suggested. (CW)
