Presents a collaborative learning exercise intended to teach the unfamiliar terminology of experimental design both in biology classes and biochemistry laboratories. The exercise promotes discussion and debate, develops communication skills, and emphasizes peer review. The effectiveness of the exercise is supported by student surveys. (SOE)

Investigates students' ideas about gravity beyond the earth's surface. Presents a lesson plan designed to help students understand that gravity can act beyond Earth's atmosphere. Also helps students gain a more adequate intuitive understanding of how natural and artificial satellites stay in orbit. Reports that this strategy changed some students'…

Describes the use of manipulatives to teach the fundamental concept of limiting factors and presents a series of questions that can be used to test whether students are harboring some of the most common misconceptions about limiting factors. Includes applications to discussions of cultural eutrophication and vegetarianism. (JRH)

The results of a study conducted with elementary school students in Tanzania are presented. A number of alternative conceptions were revealed. The role of sociocultural beliefs in forming these conceptions is described, and the implications of these findings for science teaching and teacher education are discussed. (Author/CW)

Discusses the teaching of vectors and the inadequate and inappropriate examples given in many textbooks. Suggests using the motion of a sailboat or the motion of a car moving on the Earth's surface as possible examples. Details a proper vector teaching example. (MVL)

An intervention study with 12- to 13-year-old students which attempts to move students' thinking about matter and the dissolving process toward the school science view by use of activities and group discussion tasks which directly address some of the thinking underlying students' prior ideas is described. Students responses to the strategies…

Discusses how student errors can be utilized to understand the nature of the conceptions that underlie students' mathematical activity. Looks at why errors are made in mathematics, how teachers and students perceive errors, and how to use errors in the classroom. (MDH)

Argues that entertainment media, especially feature films, have a powerful impact in shaping knowledge and beliefs about the world. Presents four ways that teachers can use feature films to enhance the teaching of world history and to counteract misconceptions that students acquire through the mass media. (DB)

Discussed are the implications of the three main stages of conceptual change--"awareness, disequilibrium, and reformulating"--on misconceptions of grade 10 students in Israel. The difficulties and problems encountered with the procedure are included. (KR)

Parrot math (memorization) seeks to control children through external rewards and punishments, rather than harness their intelligence and curiosity. Recent standardized test results document parrot math's failure. Activities-based approaches, supported by a constructivist philosophy (involving classifying, inferring, generalizing, and…

Investigates the effects of both computer animations of microscopic chemical processes occurring in a galvanic cell and conceptual-change instruction based on chemical demonstrations on students' conceptions of current flow in electrolyte solutions. Finds that conceptual change instruction was effective at dispelling student misconceptions but…

Analyzes a teaching episode to determine how a conflict is perceived and overcome by students as a result of verbal interaction between the teacher and the students. Discusses the particulate nature of matter with students aged 15-16 after observing a glass of water containing a rock and an ice cube. (Contains 25 references.) (Author/YDS)

The thinking process does not always start with problem situations that produce cognitive conflict, and the confrontation of students' misconceptions is not always successful as a teaching approach. Contends that curiosity and mystery appear to excite human thinking and could therefore be considered to be the starting point in science teaching and…

Teachers using a constructivist approach to learning are not invisible, as Lawrence Baines and Gregory Stanley suggest in a December 2000 "Kappan" article. Rather, they are an integral part of an active, student-centered learning process. Assisted by teachers, learners select and transform information, construct hypotheses, and make decisions.…

Discusses a study that revealed that science teachers, like their students, are capable of handling positive experimental results but fail to evaluate negative results appropriately. Describes a teaching strategy designed to help teachers develop an understanding of the concept of negative results and to apply the idea to different contexts.…
