Thought experiments are personal and tacit processes of experimentation that scientists perform within their own imagery in formulating new theories or refuting existing theories. However, by viewing learning as a social process, this study aims to show that thought experiments can also be constructed collaboratively and to present a detailed…

In this paper we describe student use of a series of connected online problem-solving activities to remediate atmospheric carbon budget misconceptions held by undergraduate university students. In particular, activities were designed to address a common misconception about conservation of mass when students assume a simplistic, direct relationship…

To meet the immense challenges society faces in areas such as energy, health, and environmental protection, science teachers and teacher educators need to invest in the creation of classroom cultures that turn the intellectual heavy lifting over to the students while developing students' identities as competent learners. The vision is that…

Organic Chemistry is recognized as a course that presents many difficulties and conceptual challenges for students. To combat the high failure rates and poor student attitudes associated with this challenging course, we implemented a "flipped" model for the first-semester, large-enrollment, Organic Chemistry course. In this flipped…

In this article, which includes three video clips, the author argues that the small experiments, inventions, strategies, and pauses in young children's play seen in the clips reveal a legitimate form of scientific thinking. He notes that science and play both represent a frame of mind, an attitude toward the events one observes. (Contains 3…

Compares Reform of Secondary Education (ROSE) students' and nonROSE students' perceptions of five psychosocial dimensions of their science practical tasks: student cohesiveness, open-endedness, integration, rule clarity, and material environment. Contains 17 references. (DDR)

This guide presents current scientific research on the process of human learning and stresses the importance of metacognition. Focus is placed on memory and learning with analogies to photography being employed to aid understanding. This guide also includes background information on human memory; a poster; instructions for the four short term…

Explains tendencies and difficulties experienced by students aged 14 through 17 years during an activity involving measurement in physics. Surveys these tendencies and difficulties through clinical interviews involving data collection, data processing, and data interpretation. Contains 17 references. (DDR)

Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

Discusses the use of problem-solving activities in elementary-level science lessons. Sample activities include "Sparkling Christmas Presents,""Who Left the Message?," and "Parachute Descent". (WRM)

Discussed are science activities appropriate for middle school students. Considerations include the degree of abstractness of the concepts and the need for increased class time for explaining, discussing, and integrating students' activity experiences. (DS)

This teacher's guide presents current scientific research on the process of human learning and stresses the importance of metacognition. Focus is placed on the integrated pair of concepts, emotion and attention, with analogies to traffic conditions being employed to aid understanding. Background information on human emotion and attention, a…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

Two experiments examined how learning from different media--real pulley systems or simple line diagrams--affected mechanical learning and problem solving. The first showed that subjects' learning improved equally in both cases; all subjects showed an increase in quantitative understanding as they learned; and subjects manipulating real pulley…

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)
