The limitations of traditional education models and the advancement of technology have revealed the need to transform the learning experience. The "Flipped Learning" approach, born out of this need, is a model where students study learning materials in advance and participate in more interactive and hands-on activities in the classroom.…

Inquiry methods have been successful in improving science literacy in students of all ages. Model-Based Inquiry (MBI) is an instructional model that engages students in the practices of science through the collaborative development of scientific models to explain an anchoring phenomenon. Student ideas are tested through engagement in content-rich…

A classroom demonstration model has been designed, machined and successfully tested in different learning environments to facilitate understanding of the mechanics of truss structures, in which struts are subject to purely axial load and deformation. Gaining confidence with these structures is crucial for the development of lattice models, which…

In traditional classroom discourse, the teacher controls the discussion, asking most of the questions and calling on students to respond. This model does not work well for the inquiry-based classroom, which depends on engagement, peer interaction, and student ownership of learning. In this article, the authors present an alternative framework for…

Teachers know what a daunting job it can be to ensure that all students in a class learn effectively. In addition to the usual difficulties of gaining everyone's attention at once, instructors also run into the issue of preferred learning styles. In any classroom environment, the same topic is taught to multiple students, and each student may…

This article discusses problem solving and how science educators can integrate problem solving into their instruction. The Search, Solve, Create, and Share (SSCS) model was developed based on the findings of problem solving research. (YP)

Discussed are the nature of the development of conceptual relationships, and the structure of concepts. The topics are presented with regard to the importance of combining metaphors with two alternate approaches to learning, the first being rote learning and the other being inductive learning. The paper is intended to be a model of the concept of…

Presents a framework for model development that, when used, will help the student (or professor) avoid the major pitfalls associated with modeling. Includes not properly identifying the controlling factors, lack of model validation and developing a model that is incompatible with its end use. (CW)

Presents a practical model for planning and implementing a field trip as an integral part of the science curriculum. Reviews the literature related to the role of field trips in the learning process; describes the model; and provides an example implementing the learning cycle method. (Contains 17 references.) (MDH)

Explores the applicability of Mulliken's united atom model to a variety of chemical systems and demonstrates its value as a teaching tool. Considers applications to first row hydrides, compounds of the first and second periods, heavy atoms, and cluster systems. (MVL)

Discusses the least squares technique and states the difficulty in finding suitable examples for using it in the chemical laboratory. Provides several least squares equations and the accompanying three dimensional drawings. Notes graphic lecture aids are available from the author as either slides or overheads. (MVL)

Presents three dimensional models of biological pathways for the following cycles: carbon, nitrogen, sulfur, and a combination of the three. Discusses steps involved in each cycle and breaks each cycle into trophic and environmental regions. (MVL)

Reports that young children in the pedestrian accident prone age range of four-eight years hold a variety of naive conceptions regarding speed. Proposes a primary science unit using a conceptual change approach. (MVL)
